Abstract:
Purpose A model of hybrid fillet welding is built and solved. No additional material (welding rod, etc.) is used. Heating of the welded parts is realized by laser beam with induction preheating and/or postheating. The purpose of these operations is to reduce the temperature gradient in welded parts in the course of both heating and cooling, which reduces the resultant hardness of the weld and its neighborhood and also reduces undesirable internal mechanical strains and stresses in material. Design/methodology/approach The complete mathematical model of the combined welding process is presented, taking into account all relevant nonlinearities. The model is then solved numerically by the finite element method. The methodology is illustrated with an example, the results of which are compared with experiment. Findings The proposed model provided satisfactory results even when some subtle phenomena were not taken into account (flow of melt in the pool after irradiation of the laser beam driven by the buoyancy and gravitational forces and evaporation of molten metal and influence of plasma cloud above the irradiated spot). Research limitations/implications Accuracy of the results depends on the accuracy of physical parameters of materials entering the model and their temperature dependencies. These quantities are functions of chemical composition of the materials used, and may more or less differ from the values delivered by manufacturers. Also, the above subtle physical phenomena exhibit stochastic character and their modeling may be accompanied by non-negligible uncertainties. Practical implications The presented model and methodology of its solution may represent a basis for design of welding processes in various branches of industry. Originality/value The model of a complex multiphysics problem (induction-assisted laser welding) provides reasonable results confirmed by experiments.

Abstract:
Composite sandwich structures offer several advantages over conventional structural materials such as lightweight, high bending and torsional stiffness, superior thermal insulation and excellent acoustic damping. One failure mechanism in a composite sandwich structure is the debonding of the composite facesheets from the core structure. A well-formed adhesive fillet at the interface of the honeycomb core cell walls and the laminate is a significant factor in preventing bond failure. In the present work, honeycomb composite sandwich panels are manufactured using a low-cost vacuum-bag-pressure-only out-of-autoclave manufacturing process. CYCOM®5320 out-of autoclave prepreg is used for the facesheet laminates and FM® 300-2U film adhesive is used for the facesheet-to-core bond. The manufactured composite sandwich panels are of aerospace quality with a facesheet laminate void content of around 1%. In this study, adhesive fillet formation and adhesive mechanical strength are evaluated as a function of several different sandwich construction design variables. Both aluminum and aramid Nomex® honeycomb core materials are considered to study the effect of core cell size and core material. The effect of film adhesive thickness is studied. A process for reticulation of the adhesive is applied and studied. A quantitative investigation of the adhesive fillet geometry is carried out for all the panels. Manufactured panels are evaluated for flatwise tensile strength in accordance with test method ASTM C297. Optimized combinations of core material, core density, cell size and adhesive thickness are identified. Results show that the reticulation process improves fillet formation and increases flatwise tensile properties.

Abstract:
Cutting force is one of the most important factors in the ultrasonically assisted grinding (UAG) of hard and brittle materials. Many theoretical and experimental studies show that UAG can effectively reduce cutting forces. The existing models for UAG mostly assume an ideal grinding wheel with abrasives in both the end and lateral faces to accomplish material removal, whereas the important role of the transition fillet surface is ignored. In this study, a theoretical cutting force model is presented to predict cutting forces with the consideration of the diamond abrasives in the end face, the lateral face, and the transition fillet surface of the grinding tool. This study analyzed and calculated the vibration amplitudes and the cutting forces in both the normal and tangential directions. It discusses the influences of the input parameters (rotation speed, feed rate, amplitude, depth and radius of transition fillet) on cutting forces. The study demonstrates that the fillet radius is an important factor affecting the grinding force. With an increase in fillet radius from 0.2 to 1.2 mm, the grinding force increases by 139.6% in the axial direction and decreases by 70% in the feed direction. The error of the proposed cutting force model is 10.3%, and the experimental results verify the correctness of the force model.

Abstract:
Fish is a food that is consumed by many people because fish contain high nutrition. Fillet products are diversification of fishery products that are quite popular with the community. That is because fillet products are easy to consume and have good nutritional content. However, fish fillet products are easily degraded during transportation. So that triggers traders to use hazardous materials in the form of formalin to increase the shelf life of fillet products. The shelf life of fish fillet products needs to be improved in order to obtain good quality and not be easily damaged by storing fillets at low temperatures and the addition of active ingredients in the form of honey. Honey also has antimicrobial properties so that it can be used as a food preservative. Honey can inhibit the growth of bacteria that cause decay. The purpose of this study was to determine the effect of adding honey with different concentrations on the shelf life of white pomfret (Pampus argenteus) fillets at cold temperatures. This research was experimental by making honey solutions with different concentrations (0%: 10%; 11%). This research uses a completely randomized design (CRD). The shelf life test is done by calculating the value of TPC, Protein, pH, Tvbn, and organoleptic. TPC, Protein, pH, TVBN, and organoleptic test results showed that the addition of honey with different concentrations had a significant effect on the shelf life of white pomfret fish fillets. The best concentration of adding honey is at a concentration of 5%. While the shelf life that can be accepted by consumers can reach 6 days shelf life. The results showed that honey can be used as an alternative preservative in fish fillet meat that functions as an antimicrobial and fat oxidation prevention.

Abstract:
The nanoindentation technique was used to measure the hardness and Young's modulus of semiconductor and metal thin films on a Si(100) substrate under cyclic loading. The results showed that in all instances and at a constant cyclic load that the loading curves overlapped the previous unloading curve and had a small displacement after each cyclic nanoindentation. It was observed that the plastic energies of metal materials from the first loading–unloading cycle were much larger than that observed in semiconductor materials. Furthermore, the hardness and Young's modulus of the thin films decreased when the number of cyclic nanoindentations was increased. The effect of the cyclic loading on the hardness and Young's modulus of semiconductor material was much larger than that of the metal material. Young's modulus, the hardness and the contact stiffness of thin films conform to the relationship that Young's modulus was proportional to the contact stiffness and the square root of the thin film's hardness.

Abstract:
A failure analysis has been conducted on a diesel engine crankshaft used in a commercial vehicle, which is made from 42CrMo forging steel, and the crankshaft was after induction hardening process. The fracture occurred between the 4th journal and the 4th crankpin, fracture section indicates that fatigue is the dominant mechanism of failure for this crankshaft. In order to find the failure causes, the dimension of journal boss fillet, material chemical compositions, surface hardness and depth of hardness layer were evaluated. Chemical compositions of crankshaft material, surface hardness and the depth of hardness layer are within the specified range, however the dimension of journal boss fillet is less than specified, and the transition zone of hardness layer was found on the journal boss fillet. Heavy segregation and many non-metallic inclusions aggregate zones were found from metallographic, these would lead to the reduction of endurance bending strength. FEA analysis results suggest that the dimension of journal boss fillet have an important effect on the stress and stress amplitude of the crankshaft. So the disqualification machining and material property are the main causes for the crankshaft fatigue fracture.

Abstract:
Till studien har under våren 2017 sex lärare intervjuats på tre olika skolor som är belägna i södra Sverige. De frågor som ställdes till lärarna var fokuserade på hur de använder sig av filmat material i relation till bedömning och betygsättning. Resultatet som gavs utifrån dessa studier pekar på att användningen av filmat material i skolan är ett bra verktyg för att närma sig sambedömning och likvärdig bedömning. Filmat material lyfts fram som en framgångsfaktor i förhållande till dokumentationssyfte, bedömning och betygsättning enligt de informanter som ställde upp i denna undersökning. Dock identifierade lärarna inte endast positiva saker med filmat material. De lyfte bland annat fram att elever kan uppleva ett obehag med att de filmas under lektionerna. Ett tillvägagångssätt som vissa lärare i studien använt sig av för att lätta på pressen för eleverna är att låta eleverna själva äga det filmade materialet.

O estudo das correlações entre as propriedades estruturais e magnéticas de filmes finos e ultrafinos é hoje assunto de grande interesse tanto científico como tecnológico, sendo que, dada a disponibilidade de materiais e a importância das aplicações atuais e potenciais, filmes magnéticos compostos por metais e ligas de metais de transição 3d estão entre os materiais mais investigados. O Co é um metal de transição 3d, ferromagnético, e que, em volume, apresenta estrutura hexagonal compacta (hc). Entretanto, tanto esta fase como as fases cúbica de face centrada (cfc) e cúbica de corpo centrado (ccc) podem ser estabilizadas à temperatura ambiente na forma de filmes ultrafinos, ou ainda em forma de estruturas multicamadas, e as propriedades magnéticas dos mesmos apresentam uma complexa correlação com a estrutura cristalina. Existe um grande numero de trabalhos a respeito de Co crescido sobre superfícies de Cu (cfc, parâmetro de rede a = 3,615 Å) e outros monocristais, mas nada há na literatura sobre monocamadas de Co depositadas sobre Cu90Au10, uma liga cfc com parâmetro de rede (3,66 Å) expandido de 1,0% em relação ao Cu. Investigamos aqui o crescimento, em condições de epitaxia de feixe molecular (MBE), e a estrutura de filmes de Co depositados a temperatura ambiente, com espessuras entre uma e cinco monocamadas atômicas (ML) depositadas sobre a superfície (100) da liga Cu90Au10. A composição química e a pureza da superfície do monocristal e dos filmes foram determinadas por espectroscopia de elétrons excitados por raios X (XPS). A cristalinidade da superfície do substrato, bem como a forma de crescimento e a estrutura dos filmes foram determinados por difração de elétrons de baixa e alta energia, LEED e RHEED. A morfologia da superfície do cristal de Cu90Au10(100) e das primeiras monocamadas do filme de cobalto foram determinadas através de medidas de microscopia de varredura por tunelamento (STM). Medidas de magnetometria por efeito Kerr magneto- óptico foram utilizadas para se estabelecer, em caráter preliminar, uma correlação entre a estrutura e o magnetismo dos filmes de Co sobre Cu90Au10(100) Nossos resultados indicam o crescimento de Co com estrutura tetragonal de face centrada (tfc), e uma evolução, com o aumento da espessura de cobalto, de formação de ilhas para crescimento camada a camada. Além disso, nota-se para os filmes de Co uma rápida contração do parâmetro de rede no plano, atingindo aproximadamente 2,5% para ~ 4,0 ML, quando comparado ao substrato de Cu90Au10 (100). Medidas de magnetometria por Efeito Kerr Magneto-ótico indicam magnetização no plano do filme. Este trabalho eminentemente experimental representou um amplo aprendizado no uso e exploração das potencialidades de técnicas múltiplas (LEED, RHEED, XPS, AES, STM e MOKE) para a adequada caracterização e investigação das propriedades estruturais e magnéticas de superfícies e nanoestruturas heteroepitaxiais preparadas em UHV, em condições de epitaxia de feixe molecular (MBE), bem como o primeiro estudo do crescimento de monocamadas de Co depositadas sobre Cu90Au10(100).
The investigation of correlations between structural and magnetic properties of thin and ultrathin films is of great scientific and technological interest presently. Due to importance of their actual and potential applications, films of 3d metals and their alloys are among the most investigated materials. Co is a ferromagnetic 3d metal that in bulk has a hexagonal compact structure (hcp). For Co films or multilayers, the hcp as well as the face-centered (fcc) and bodycentered cubic (bcc) phases can be stabilized at room temperature, depending on the used substrate. It is known that the preparation method can affect decisively the structural and magnetic properties of Co monolayers. There is a big amount of work on Co films grown on different Cu surfaces (fcc; lattice parameter a = 3.615 Å) and other substrates but, to the best of our knowledgement, there is no studies on Co monolayers deposited on Cu90Au10(100), a fcc alloy with lattice parameter of about 3.66 Å. In this work we investigate the epitaxial grow and the structure of Co films with thickness up to 5 atomic monolayers (ML) deposited on Cu90Au10(100). The goal of the study was to investigate the modifications in the magnetic properties of the Co films provided by small distortions in the lattice, since Cu90Au10 presents cfc structure with a lattice parameter ~1% larger than the one of the pure Cu. The sample preparation and the majority of the experimental analysis has been done in ultra high vacuum under molecular beam epitaxy conditions. The studies were conducted in situ, in UHV, by using x-ray photoelectron spectroscopy (XPS), high and low energy electron diffraction (RHEED and LEED), and scanning tunneling microscopy (STM). Preliminary magnetic measurements on the correlation structure - magnetism were conducted by magneto-optical Kerr effect (MOKE). Our results indicate the growth of a tetragonal distorted face centered (fct) Co lattice and an initial formation of islands followed by a layer-by-layer grow starting from 2 ML Co. The lateral lattice parameter shows a fast contraction with increasing thickness when compared to the CuAu substrate, reaching ~ 2.5% at 4 ML Co. Surface magnetometry by Magneto-optical Kerr effect indicated in-plane magnetization of the Co films. This experimental work represented a broad and extensive learning process on preparation and characterization of heteroepitaxial nanostructures by multiple techniques (LEED, RHEED, XPS, AES, STM, and MOKE) under MBE conditions (UHV) and the first investigation of Co monolayers on Cu90Au10(100).

Abstract:
Dispositivos spintrônicos baseados no transporte de corrente polarizada em spin, torque de spins e em outros fenômenos representam grandes promessas no cenário da tecnologia de miniaturização dos dispositivos eletrônicos da atualidade. Materiais magnéticos de grande relevância tecnológica para diferentes áreas envolvem, apesar de exceções, filmes e estruturas multicamadas com alta complexidade. Avanços nesta área exigem o da estrutura das mesmas, em escala atômica, possibilitando o ajuste de suas propriedades físicas. O propósito deste trabalho é a preparação de estruturas multicamadas por sputtering, bem como o estudo de fenômenos magnéticos envolvidos nestas estruturas. O objetivo é produzir uma válvula de spin. Esta é uma estrutura multicamada composta por dois filmes ferromagnéticos separados por um espaçador não magnético. A magnetização de uma das camadas ferromagnéticas é livre para girar sob efeito de pequenos campos externos, enquanto a magnetização da outra camada ferromagnética permanece fixada por meio de acoplamento de troca com uma camada antiferromagnética. A estrutura é ajustada para permitir que pequenos campos magnéticos aplicados possam chavear a magnetização das camadas ferromagnéticas, de um estado antiparalelo à um estado paralelo, resultando na variação da resistividade elétrica da estrutura (efeito GMR). Otimização das condições de deposição foi necessária para obter estruturas com acoplamento por polarização de troca, e acoplamento antiferromagnético através do espaçador não magnético. A correlação entre as condições de deposição e as propriedades magnéticas dos filmes foi estudada. O trabalho apresentado nesta dissertação tem contribuído para a caracterização de filmes finos magnéticos, quais podem ser utilizados na produção de sensores magnéticos, e do novo sistema de sputtering montado no Laboratório de Física Aplicada do CDTN.

The purpose of this work is the preparation of multilayered structures by sputtering, as well the study of magnetic phenomena involved in this structures. The aim is to produce a spin valve. This is a multilayer structure composed of two ferromagnetic layers, separated by a non magnetic spacer. The magnetisation of one of the ferromagnetic layers is free to rotate under the effect of small external fields, whilst the magnetisation of the other ferromagnetic layer remains fixed by means exchange coupling to a antiferromagnetic layer. The structure is tailored to allow the small applied magnetic fields to switch the magnetisation of the ferromagnetic layers from antiparallel state to a parallel state resulting in the variation of the electrical resistivity of the structure (GMR effect). Optimization of deposition conditions was required to obtain structures with exchange bias coupling, and antiferromagnetic coupling through a non magnetic spacer. The correlation between the deposition conditions and the magnetic properties of the films was studied. The work presented in this dissertation has contributed to the characterisation of both magnetic thin films, which can be used on the production of magnetic sensors, and the new sputtering system assembled in the Applied Physics Laboratory of CDTN.

O material estudado neste trabalho é um híbrido orgânico-inorgânico denominado di-ureasil formado por uma cadeia tipo poliéter unida em ambas extremidades a um grupo siloxano por pontes de uréia. As curvas de SAXS mostram um pico de interferência característico, atribuído a uma correlação espacial existente entre as partículas de siloxanos. Um complexo formado entre zircônio e ácido metacrílico foi adicionado ao material base e o aumento do teor deste complexo leva a um alargamento das bandas e um deslocamento de q para valores maiores. O alargamento é devido ao aumento na dispersão das distâncias interpartículas e o deslocamento pode ser devido a interação do zicônio com a região polimérica levando a uma diminuição das distâncias entre as partículas de siloxanos. As mesmas informações podem ser obtidas a partir das curvas de difração de raios X. A desconvolução gaussiana das curvas experimentais indica a formação de nanodomínios de óxido de zircônio. As curvas de transmissão na região do infravermelho mostram a interação dessas espécies de zircônio com a região polimérica da matriz híbrida. Entretanto, a competição pela água do meio reacional entre espécies de Zr e Si levam a uma diminuiçào no grau de condensação das espécies de siloxano evidenciada pelo aparecimento de bandas relativas a silanóis residuais apenas para amostras com alta concentração de zircônio. Este fato é confirmado pelas análises de RMN de 29Si. As propriedades ópticas dos di-ureasis também foram estudadas. Uma banda larga de emissão que cobre a parte do visível do espectro eletromagnético é devida à combinação de duas componentes atribuídas à processos de recombinação doador-aceptor, que ocorre entre grupos NH das ligações uréia e nos centros de siloxanos.
The base material studied is the organic-inorganic host termed di-ureasil formed by poly(ether)-based chains grafted at both ends to a siloxone backbone through urea cross linkages. SAXS curves display a characteristic interference peak attributed to the spatial correlation between siloxane nanoparticles. A methacrylate modified zirconium alcoxide (Zr- AMA) was added to this base host and the increasing addition leads to broadening and q shift to higher values. Broadening is due to increasing dispersion in the interparticle distances and the shift could be due to zirconium interaction with the polymeric part leading decreasing distances between siloxane particles. Essentially the same information is obtained from XRD curves. Gaussian deconvolution of the experimental curves indicate the formation of zirconium oxide based nanodomains. FT-IR spectra analysis have shown the interaction of the zirconium based species with the polymeric part of the hybrid host. Moreover competition for water between Si and Zr species lead to decrease on the condensation degree of siloxane species as evidenced by the appearence of characteristic silanol bands only for higher Zr content. This fact is confirmed by 29Si NMR. The optical properties of the di-ureasils were also studied. A broad emission band covering the visible part of the electromagnetic spectrum is attributed to the convolution of two components assigned to radiative recombination processes typical of donor-acceptor pairs occurring in the NH groups of the urea cross-links and in the siliceous nanodomains. With the addition of Zr-AMA broadening is observed. Luminescence spectroscopy shows that the addition of highly emitting Eu3+ â -diketonate complex [Eu(tta)3(H2O)2] (where tta stands for thenoiltrifluoribetadiketonate) to the di-ureasil host has lead to interesting features.

Abstract:
Neste trabalho calculamos inicialmente as propriedades ópticas de filmes compósitos de Me-NiO e Me-CoO, sendo os metais Me = Au, Ag, Cu, Ni, Pd e Pt, a partir da teoria de meio efetivo de Maxwell Garnett. Este estudo teórico possibilitou avaliar a viabilidade de se obter experimentalmente um material colorido na região do espectro visível, com absorção seletiva numa estreita faixa de comprimentos de onda. Os resultados mostraram que o candidato ideal para tal fim é o compósito a base de Au. A partir deste resultado iniciou-se o crescimento de filmes finos compósitos de Au-NiO e Au-CoO, utilizando diferentes estratégias experimentais: (i) deposição por DC magnetron sputtering reativo, (ii) deposição do filme de NiO, por DC magnetron sputtering reativo e Au pelos métodos de sol-gel e dip coating e (iii) deposição de ambos os filmes, NiOxHy e Au, por sol-gel e dip coating. Os resultados mostraram uma seletividade pequena (-5-10%) nos filmes crescidos pelo método de sputtering, devido ao caráter atomístico desse tipo de técnica, que conduz à formação de pequenos aglomerados de Au (menores que -3 nm), ao invés de agregados com tamanhos da ordem de algumas dezenas de nanômetros, obtidos facilmente pelo método sol-gel. O crescimento na forma de multicamadas proporciona uma melhor seletividade, em torno de 1 5%. Pós-tratamentos térmicos em filmes compósito s obtidos unicamente por sputtering induzem a aglomeração do Au, mas destroem as propriedades eletrocrôrnicas. No caso de filmes de Au crescidos por sol-gel, a seletividade espectral, decorrente da presença do Au aumenta, indo de 15% a 20% em filmes depositados sobre a matriz óxida crescida por sputtering e por sol-gel, respectivamente. Mediante processos eletroquímicos, os filmes de NiOxHy crescidos por sol-gel e dip coating apresentaram os melhores resultados de variação de transmitância (70%), devido à maior porosidade desses filmes.
In this work we initially calculated the optical properties of cermet films of Me-NiO and Me-CoO, being the metals Me = Au, Ag, Cu, Ni, Pd and Pt, by means of the Maxwell Garnett effective medium theory. This theoretical study allowed evaluating the viability to obtain, experimentally, a colored material in the visible spectrum region, with selective absorption in a narrow range of wavelengths. The results showed that the ideal candidate for such goal is the Au cermet. Looking at this result, the growth of Au-NiO and Au-CoO thin films was initiated using different experimental strategies: (i) deposition by reactive DC magnetron sputtering, (ii) deposition of the NiO, film by reactive DC magnetron sputtering and Au by the sol-gel and dip coating methods and (iii) deposition of both films, NiOxHy and Au, by sol-gel and dip coating. The films grown by sputtering showed a small selectivity (-5-10%), due to the atomistic character of this type of technique. It leads to the formation of small clusters of Au (smaller than -3 nrn), instead of aggregates with sizes of the order of some tenths of nanometers, easily obtained by the sol-gel method. Better selectivity, around 15%, is obtained in films deposited as multilayers. Post thermal annealing of the cermet films grown by sputtering induces the agglomeration of Au, but destroys the electrochromic properties. In the case of Au films grown by sol-gel, the spectral selectivity increases, due to the presence of Au, going from 15% to 20% in films deposited on the oxide matrix, deposited by sputtering and sol-gel, respectively. Under electrochemical processes, the NiOxHy films grown by sol-gel and dip coating presented the highest transmission variation (70%), due to larger porosity of these films.

Resumo: O composto acetilacetonato de alumínio, AAA, é normalmente utilizado para sintetizar filmes de alumina pelo método de deposição química de vapor (Chemical Vapor Deposition, CVD). Estudos recentes têm demonstrado também a possibilidade de se criar filmes à base de alumínio a partir do sputtering reativo deste composto em plasmas de radiofrequência de misturas de argônio e oxigênio. O objetivo do presente trabalho foi avaliar a possibilidade de utilizar tensão contínua pulsada, DC, diferentemente dos relatos da literatura, para depositar filmes à base de Al pelo sputtering reativo do AAA. Esta proposta é justificada pelo fato da excitação com tensão contínua pulsada na configuração elétrica aqui empregada, permitir o simultâneo aquecimento do composto precursor e das amostras, ao mesmo tempo em que proporciona o estabelecimento do plasma. Além de favorecer a criação de estrutura estequiométrica, pela remoção de orgânicos, o aquecimento pode possibilitar a precipitação de fases cristalinas da alumina. Para realização deste trabalho foi utilizado um reator capacitivamente acoplado em que o pó do AAA foi acondicionado no centro do eletrodo inferior e os substratos acomodados ao seu redor. O plasma foi estabelecido pela aplicação de sinal DC pulsado (-300 à -400 V, 20 kHz, pulsos 48/50 µs) no único eletrodo (porta amostras) enquanto toda a carcaça e tampa superior permaneceram aterrados.

Abstract: The aluminum acetylacetonate compound, AAA, is usually used to synthesize alumina films by the chemical vapor deposition method (CVD). Recent studies have also demonstrated the possibility of creating aluminum-based films from the reactive sputtering of this compound in radiofrequency plasmas of argon and oxygen mixtures. The purpose of the present study was to evaluate the possibility of using pulsed DC voltage, another the literature reports, to deposit Al based films by AAA reactive sputtering. This proposal is justified by the fact that pulsed continuous voltage excitation in the electrical configuration employed here allows the simultaneous heating of the precursor compound and samples, while providing the establishment of the plasma. In addition to favoring the creation of a stoichiometric structure, by the removal of organic, the heating may allow the precipitation of crystalline phases of the alumina. To perform this work, a capacitively coupled reactor was used in which the AAA powder was conditioned at the center of the lower electrode and the substrates accommodated around it. Plasma was established by applying pulsed DC signal (-300 to -400 V, 20 kHz, pulses 48/50 μs) on the single electrode (sample holder) while the entire housing and top cover remained grounded. Two different conditions were investigated. The first one evaluated the effect of plasma excitation signal power, P, varied from 200 to 500 W and the effect of time, t, on films produced with plasma (200...

Resumo: Os tratamentos de superfície a plasma são amplamente usados em diversas áreas de tecnologia, tais como: indústria metalmecânica, microeletrônica, plástico e medicina, para o crescimento de filmes finos, camadas protetoras em instrumentos e ferramentas de corte, funcionalização de superfícies plásticas, tecidos sintéticos, esterilização de instrumentos cirúrgicos e plasma reativo em semicondutores. Há alguns anos, uma nova família de filmes duros e protetores com baixo atrito compostos por nanoestrururas, tem sido intensamente pesquisada por apresentar propriedades particularmente interessantes, do ponto de vista da físico-química básica, como possíveis aplicações tecnológicas em que a demanda por desgaste, altas temperatura, e resistência mecânica são necessárias. A deposição de filmes finos, constituídos por nanocompósitos, e a compreensão de propriedades (mecânicas, elétricas, ópticas) desses novos materiais, gera um leque de possíveis aplicações tecnológicas. A partir de tais premissas, focalizamos o objetivo do trabalho em estudar a obtenção e caracterização das propriedades físico-químicas de filmes finos nanoestruturados (nanocompósitos), que contêm compostos de Ti, C, N, e O, utilizando a técnica de Deposição Química pela Decomposição do precursor líquido tetraetóxido de titânio (Ti(OC2H5)4) (PECVD, na sigla em inglês). Ressalta-se que o interesse em obter esses materiais, a partir do reagente em questão, reside no fato de que ele poderia substituir o uso de outros precursores de difícil manuseio, tais como o tetracloreto de titânio (TiCl4), o qual é normalmente utilizado em numerosas aplicações de deposições de filmes compósitos, mediante a técnica de PECVD, e cujo subproduto da reação gera reagentes altamente corrosivos. Em resumo, este trabalho contempla a caracterização da composição química, micro e nano estrutura de compósitos que contêm os compostos mencionados, em função das variáveis mais importantes de deposição. O presente estudo foi bem sucedido em obter nanocompósito e correlacionar a dependência das ligações químicas do material com os parâmetros mais importantes de deposição
Abstract: Plasma surface treatments are widely used in several technological areas (e.g., metallurgic industry, microelectronic, plastic industry, medicine) in order to obtain hard coatings on cutting tools and instruments, funtionalization of plastics and synthetic materials used in the textile industry, sterilization of chirurgic instruments, etching by reactive plasma in the semiconductor industry, etc. Recently, a new family of coatings deposited by plasma assisted techniques owing interesting physical chemical properties such as super-hardness, low friction and wear resistant, temperature and corrosion resistant, known as nano-composites, have been intensely studied.The objectives of this work is developing a nano composite containing Ti, C, N e O and understand as far as possible its physical and chemical properties. The material is obtained by plasma assisted enhanced chemical deposition (PECVD) using Titanium(IV) ethoxide ( (Ti(OC2H5)4) and N as precursors of the reaction. The importance of the attempt to use the cited precursor resides in the fact that it is a friendly liquid without corrosive o major toxic effects, as the normal precursors used in the actual industrial process (e.g., titanium tetrachloride, TiCl4). Summarizing, this work is focusing the research in the deposition and study of the physical and chemical properties of thin films nano composites obtained from Titanium(IV) ethoxide precursor. The study shows that the deposition procedure allows obtaining a material containing nanoscopics size crystallites of the compounds cited above. Finally, the relation of the material properties with the more important deposition parameters is discussed and presented

Abstract:
For crystal materials, thermal conductivity (TC) is proportional to T3 at low temperatures and to T−1 at high temperatures. TCs of most amorphous materials decrease with the decreasing temperatures. If a material is thin film, boundary will influence the TC and then influence the temperature dependence. In this paper, we calculate the TC of crystal and amorphous SiO2 thin films, which is a commonly used material in micro devices and Integrated Circuits, by NEMD simulations. The calculation temperatures are from 100K to 700K and the thicknesses are from 2nm to 8nm. TCs of crystal thin films reach their peak values at different temperatures for different thicknesses. The smaller thickness the larger peak values obtained. But for amorphous thin films, the results show that the temperature dependence of thin films is the same as bulk materials and not relative to their thicknesses. The obtained temperature dependence of the thin films is consistent with some previous measurements and the theory predictions.

Abstract:
Magnetic responsive materials can be used in a variety of applications. For structural applications, the ability to create tunable moduli from relatively soft materials with applied electromagnetic stimuli can be advantageous for light-weight protection. This study investigated magnetorheological composite materials involving carbonyl iron particles (CIP) embedded into two different systems. The first material system was a model cementitious system of CIP and kaolinite clay dispersed in mineral oil. The magnetorheological behaviors were investigated by using parallel plates with an attached magnetic accessory to evaluate deformations up to 1 T. The yield stress of these slurries was measured by using rotational and oscillatory experiments and was found to be controllable based on CIP loading and magnetic field strength with yield stresses ranging from 10 to 104 Pa. The second material system utilized a polystyrene-butadiene rubber solvent-cast films with CIP embedded. The flexible matrix can stiffen and become rigid when an external field is applied. For CIP loadings of 8% and 17% vol %, the storage modulus response for each loading stiffened by 22% and 74%, respectively.
