Abstract:

AbstractStructural coloration using metasurfaces has been steadily researched to overcome the limitations of conventional color printing using pigments by improving the resolution, lowering the toxicity, and increasing the durability. Many metasurfaces have been demonstrated for dynamic structural coloration to convert images at the visible spectrum. However, the previous works cannot reach near-zero scattering when colors are turned-off, preventing it from being cryptographic applications. Herein, we propose a completely on/off switchable structural coloration with polarization-sensitive metasurfaces, enabling full-colored images to be displayed and hidden through the control of the polarization of incident light. It is confirmed that the nanostructure exhibits the polarization-dependent magnetic field distributions, and near-zero scattering is realized when the polarization of incident light is perpendicular to the long axis of the nanofins. Also, the metasurfaces are made up of triple-nanofin structures whose lengths affect locations of resonance peaks, resulting in full-color spectrum coverages. With such advantages, a QR code image, a two-color object image, and an overlapped dual-portrait image are obtained with the metasurfaces. Such demonstrations will provide potential applications in the fields of high-security information encryption, security tag, multichannel imaging, and dynamic displays.

Abstract:

TiO2/SiO2 complex nanofilm with high transmittance on solar cell glass was prepared by sol-gel method. Particle diameters, surface structures, the thickness of nanofilm and the transmittance of light from 400nm to 1100nm were tested with AFM, UV2550 and other instruments. The mole percents of TiO2 in SiO2 and their ratio influences on the transmittance of glass, aging ability and other properties of nanofilm were investigated. The AFM photos demonstrated that the TiO2/SiO2 film with high transmittance were composed of nanoparticles with 10nm to 30 nm diameters and their structures were meshes with many holes whose diameters were from 300nm to 500nm. The results revealed that as the mole percents of TiO2 in SiO2 increased the transmittance of solar cell glass with TiO2/SiO2 nanofilm decreased but the aging, adhering and wearing abilities increased and as the diameters of nanoparticles decreased the transmittances of solar cell glass with TiO2/SiO2 nanofilm increased under the condition of TiO2/SiO2 nanofilm with meshes of 300nm to 500m diameters of holes. When the mole percents of TiO2 in SiO2 were 0.1%~0.3%, the average diameters of particles in TiO2/SiO2 nanofilm were about 10nm and the structures of TiO2/SiO2 nanofilm were the meshes with many gaps and the diameters of holes were 300nm to 500nm. The increased transmittances were the greatest about 3.6%, increased value of solar cell efficiency about 3.8% and the aging, adhering and wearing abilities of TiO2/SiO2 nanofilm were best for 20 year life through rapid aging tests.

Abstract:

It is very essential to know mechanical properties in different regions of nanobio membrane as one of the most important parts of living systems. Here the coarse-grained (CG) simulations method have been used to study the pressure profile in a system including nanobio membrane and water. CG simulations have become an important tool to study many biomolecular processes, exploring scales inaccessible to traditional models of atomistic resolution. One of the major simplifications of CG models is the representation of the solvent, which is either implicit or modeled explicitly as a van der Waals particle. The effect of polarization has been ignored in the initial CG water molecules model. Given the important role of water as a solvent in biological systems, its treatment is very important to the properties derived from simulation studies. Till now two models have been parameterized to simulate water: i) standard MARTINI water and ii) polarizable coarse-grained water model. Both of mentioned water models are proper to be used in combination with the CG MARTINI force field. In this work both of these models have been used for simulation. One micro second CG molecular dynamics simulation has been done for two separate systems. Each system includes water and hydrated 1-palmitoyl-2-oleoyl-1-sn-3-phosphatidylcholine (POPC) lipid nanobio membrane. The difference between two systems is in simulated water models that one system has standard MARTINI water and the other one has polarizable water. In each case pressure profile calculation has been done via Virial pressure theorem. Results indicate that using polarizable water model leads to higher picks in pressure profile in water region near surface of nanobio membrane. This can be related to density of polarizable water and also may play role as a small barrier.

Abstract:

A polypeptide nanofilm made by layer-by-layer (LbL) self-assembly was built on a surface that mimics nonwoven, a material commonly used in wound dressings. Poly-L-lysine (PLL) and poly-L-glutamic acid (PLGA) are the building blocks of the nanofilm, which is intended as an enzymatically degradable lid for release of bactericides to chronic wounds. Chronic wounds often carry infection originating from bacteria such as Staphylococcus aureus and a release system triggered by the degree of infection is of interest. The dry nanofilm was studied with ellipsometry. The thickness of the nanofilm was 60% less in its dry state than in its wet state. The measurements showed that a primer was not necessary to build a stable nanofilm, which is practically important in our case because a nondegradable primer is highly unwanted in a wound care dressing. Added V8 (glutamyl endopeptidase) enzymes only showed adsorption on the nanofilm at room temperature, indicating that the PLL/PLGA “lid” may remain intact until the dressing has been filled with wound exudate at the elevated temperature typical of that of the wound.

Abstract:

We have observed surface plasmon resonances (SPR) in Au thin films between 18 nm to 27 nm thick deposited onto glass substrates. The observed resonance angles are between 15.5 to 18.75 degrees, which are lower than predicted theoretical values for thicker films. The shift of resonances with the change of refractive index of surrounding confirms its application for nanobio-sensing. A thorough topological surface analysis and transmitted spectra were performed. Au thin films were annealed in Argon and the analysis repeated and compared with those from pre-annealing. The annealing process will cause a sharper appearance of surface plasmon resonances which will make these thin film devices a more suitable candidate for nanobio-sensing applications.

Abstract:

Abstract Background Improvements in skin erythema and elasticity have been observed with topical application of platelet-rich plasma after fractional laser (FXD) treatment. Injections of nanofat via small needles into the dermis improves tissue thickness, discoloration and wrinkle depth. Objectives The aim of this study was to evaluate improvements in skin following a nonablative FXD treatment combined with the application of a novel topical nanofat biocrème, called neo-U. Methods Fifty patients were treated with a nonablative FXD followed by application of a topical nanofat biocrème. Harvested fat was processed into nanofat, which was compounded with a transdermal liposomal delivery vector to produce a topical biocrème. In 2 patients, postauricular skin punch biopsies were performed before and after treatment and examined for histologic changes. Photographs of a historical group treated with only the FXD were compared with photographs of patients treated with a combination of topical nanofat biocrème and FXD. Skin types were evaluated for improvements in nasolabial folds, wrinkles, and skin texture. Results Findings from postauricular skin biopsies show the skin exposed to FXD with nanofat biocrème had more elastin fibers and a slight increase in the thickness of the epidermis. Patients treated with FXD plus nanofat biocrème had a statistically significant improvement in the degree of wrinkles, nasolabial fold depth, and texture compared with historical controls. Conclusions Transdermal delivery of nanofat topical biocrème applied after FXD treatment can serve as a delivery system to improve fine lines, nasolabial fold depth, and overall texture of the tissue to a greater degree than laser resurfacing alone.

Abstract:

Nanoestruturas metálicas são alvo de frequentes estudos devido ao seu potencial, tanto para aplicações em dispositivos tecnológicos miniaturizados, quanto para fins de compreensão básica de suas propriedades, que são por vezes muito distintas daquilo que observamos na escala macroscópica. Nesse contexto, uma classe importante de estrutura são os nanofios, que são definidos ou como um tarugo com décimos de nanômetros, com uma das dimensões maiores do que as demais, ou como uma cadeia linear suspensa (LAC – Linear Atomic Chain), que consiste em uma cadeia de átomos únicos ligados par a par em uma direção. Efeitos devido ao empilhamento da rede cristalina e ganhos em energia de superfície influenciam e alteram a morfologia e a formação de nanofios. Buscamos nesse trabalho estudar computacionalmente, através de simulações numéricas, a formação de nanofios, via processo de alongamento, efetivamente simulando o efeito do puxamento de uma barra nanométrica. Usamos código próprio desenvolvido em linguagem C-CUDA para realizar as simulações. Para ligas metálicas de NiTi, alguns desafios que se apresentam são: a incorporação de condições de contorno, velocidades de puxamento, assim como o fato de que transições de fase ocorrem no material durante a dinâmica, transições essas que caracterizam o chamado efeito de memória de forma que o material apresenta.

Abstract:

Aflatoxicosis is a cause of economic losses in broiler production. In this study, the effect of one commercial nanocompound, Nanocid (Nano Nasb Pars Co., Iran) was evaluated in reduction of aflatoxin effects on the growth and performance indices in broiler chickens suffering from experimental aflatoxicosis. For this, a total of 300 one-day-old broiler chicks (Ross strain) were randomly divided into 4 groups with 3 replicates of 15 chicks in each separated pen during the 28-day experiment. Treatment groups including group A: chickens fed basal diet, group B: chickens fed 3 ppm productive aflatoxin in basal diet, group C: chickens fed basal diet plus 2500 ppm Nanocid, and group D: chickens fed 3 ppm productive aflatoxin and 2500 ppm Nanocid, in basal diet. Data on body weight, body weight gain (BWG), feed intake, and feed conversion ratio (FCR) were recorded at weekly intervals. Also cumulative data were assessed. Results showed, although supplement of Nanocid to conventional diet had no effect on performance but addition of Nanocid to diet containing 3 ppm aflatoxin increased significantly the cumulative BWG, cumulative feed consumption and decreased FCR in the last 2 weeks of experimental period. The improvement in these performance indices by supplement of Nanocid to diet containing aflatoxin showed the ability of Nanocid to diminish the inhibitory effects of aflatoxin.

Abstract:

In order to take good advantage of polysilicon nanofilm, optimized technical characteristics of the polysilicon nanofilm are very necessary to investigated. In this paper, the polysilicon nanofilms were prepared under different technical parameters, including thickness and doping concentration, which are very important for preparation of the nanofilm. The experimental results of piezoresistive and temperature characteristics show that the optimized technical characteristics are followed, the thickness is about 90nm, and the doping concentration is about 4.1×?1019cm-3 or between 2.0×?1020cm-3 and 4.1×?1020cm-3 from different point of view. The investigations of optimized technical characteristics are very useful for application of the polysilicon nanofilm to piezoresistive sensor.

Abstract:

Nanofer zerovalent iron (nanofer ZVI) is a new and innovative nanomaterial capable of removing organic as well as inorganic contaminants in water. It displays a decrease in agglomeration, when it is coated with tetraethyl orthosilicate (TEOS). TEOS imparts an increase in reactivity and stability to nanofer ZVI. Characteristics of nanofer ZVI were determined using scanning electron microscope/electron dispersive spectroscope (SEM/EDS), transmission electron microscope (TEM), and X-ray diffraction (XRD). Nanoparticle size varied from 20 to 100 nm and its surface area was in the range of 25–30 m2g−1. The present study examined its structure before and after kinetic experiments. Kinetic experiments indicated that adsorption of heavy metals [Pb (II), Cd (II), and Cu (II)] and TCE is very rapid during the initial step which is followed by a much slower second step. Removal rates of 99.7% for Pb (II), 99.2% for Cd (II), 99.9% for Cu (II), and 99.9% for TCE were achieved in less than 180 minutes. Lagergren models (LM), liquid film diffusion model (LFDM), and interparticle diffusion model (IDM) were used to understand the removal mechanism associated with nanofer ZVI. In this study, interactions of nanofer ZVI with individual metals as well as TCE are examined.

Abstract:

Graphene has been extensively investigated in advanced photodetection devices for its broadband absorption, high carrier mobility, and mechanical flexibility. Due to graphene’s low optical absorptivity (2.3%), graphene-based photodetection research so far has focused on hybrid systems to increase photoabsorption. However, such hybrid systems require a complicated integration process and lead to reduced carrier mobility due to heterogeneous interfaces. Crumpled or deformed graphene has previously been reported in electronics and optoelectronics. However, a depth study on the influence of the morphology of nanofilms (e.g., graphite or graphene) related to light absorption in photodetection devices has not been demonstrated yet. Here, we present an interesting study in terms of the effect of the deformable surface and the smooth surface of a nanofilm transferred onto Si through two transfer strategies using isopropanol injection and nitrogen blowing (to form a deformable nanofilm surface) and deionized water injection and van der Waals interaction (to form a smooth nanofilm surface). As a result, optical detection in the case of the deformable nanofilm surface was enhanced significantly (~100%) compared with that of the smooth nanofilm surface in the visible laser wavelength (532 nm). In addition, evidence from the computational simulation also firmly affirms an advancement in the optical detection of deformed nanofilm-surface-based photodetection devices compatible with the experimental results.

Abstract:

Lavandin essential oil (LEO), a natural sterile hybrid obtained by crossbreeding L. angustifolia × L. latifolia, is mainly composed by active components belonging to the family of terpenes endowed with relevant anti-proliferative activity, which can be enhanced by proper application of nanotechnology. In particular, this study reports the chemical characterization and the screening of the anti-proliferative activity on different human cell lines of pure and nano-formulated lavandin essential oil (EO). LEO and its formulation (NanoLEO) were analyzed by HS/GC-MS (Headspace/Gas Chromatography-Mass Spectrometry) to describe and compare their chemical volatile composition. The most abundant compounds were linalool and 1,8-cineole (LEO: 28.6%; 27.4%) (NanoLEO: 60.4%; 12.6%) followed by α-pinene (LEO: 9.6%; NanoLEO: 4.5%), camphor (LEO: 6.5%; NanoLEO: 7.0%) and linalyl acetate (LEO: 6.5%; NanoLEO: 3.6%). The cytotoxic effects of LEO and NanoLEO were investigated on human neuroblastoma cells (SHSY5Y), human breast adenocarcinoma cells (MCF-7), human lymphoblastic leukemia cells (CCRF CEM), human colorectal adenocarcinoma cells (Caco-2) and one normal breast epithelial cell (MCF10A) by the MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide)-assay. Caco-2, MCF7 and MCF10A normal cells resulted more resistant to the treatment with LEO, while CCRF-CEM and SHSY5Y cells were more sensitive. The antiproliferative effect of LEO resulted amplified when the essential oil was supplied as nanoformulation, mainly in Caco-2 cells. Scanning and transmission electron microscopy investigations were carried out on Caco-2 cells to outline at ultrastructural level possible affections induced by LEO and NanoLEO treatments.

Abstract:

Ag/TiO2/Eu-MCM composite was prepared by a nanofilm of silver coating on a nanofilm of anatase TiO2assembled onto the internal and external pore surface of a hierarchical micro/meso/macroporous molecular sieve Eu-MCM. The composites Ag/TiO2/Eu-MCM exhibited significant photocatalytic characteristics with more than four times higher UV-Vis-induced catalytic degradation for phenol than that of pure TiO2. The result is attributed to the composites possess vast specific surface areas, big pore width in favor of mass transfer, strong absorbance of nanofilm silver to UV-Vis light, rapid photoelectron transfer from excited nanofilm of TiO2to silver nanofilm, and reduction of the recombination probability of hole and photoelectron. There exists an excellent linear correlation with a correlation coefficient 0.979 between photocatalysis and fluorescence of the composite. A photocatalytic intermediate benzoquinone was measured using HPLC techniques during the process of photocatalytic degradation phenol under a weak UV-Vis radiation condition that indicated organic phenol was first oxidized into benzoquinone and finally degraded into inorganic species of carbon dioxide and water.

Abstract:

AbstractBackgroundNanofats could improve photoaging. Stromal vascular fraction (SVF) and adipose-derived stem cells (ADSCs) may play pivotal roles. However, SVFs and ADSCs in nanofats processed by conventional methods cannot be enriched. Some researchers have found that after centrifugation, the SVF/ADSC density increases from top to bottom.ObjectivesThe authors hypothesized that centrifugation can be used to obtain SVF/ADSC-concentrated nanofats that are superior to conventional nanofats in improving the photoaging of skin.MethodsAfter a photoaging model was successfully established in nude mice, the back of each mouse was divided into 4 areas and randomly injected with conventional nanofat, centrifuged nanofat (either the middle or lower layer of centrifuged nanofat), or normal saline. Wrinkles, dermis thickness, dermal collagen content, and elastic fiber morphology were measured and compared at weeks 4 and 8.ResultsCompared with the wrinkles in the physiological saline injection areas, the wrinkles in the areas injected with the 3 nanofats (lower and middle layers of centrifuged nanofat and conventional nanofat) were significantly reduced. All 3 nanofat groups showed increased dermal thickness, increased collagen content, and a more regular distribution of elastic fibers compared with the saline injection areas.ConclusionsThe study established the efficacy of nanofats in improving photoaging by reducing wrinkles and increasing the thickness of dermal collagen, making nanofats a promising novel treatment for photoaging. The SVF/ADSC-concentrated nanofats exhibited the most improvement.

Full text

Abstract:

In the paper, molecular dynamics simulation with the modified analytical embedded atom method (MAEAM) is applied to study the size effect on the elastic properties of the B 2- NiAl nanofilm. The simulation results indicate that there is a critical thickness, which is about 5.38 nm, to distinguish the size dependence of the elastic properties of the nanofilm. On the one hand, these properties, such as the averaged cohesive energy and the bulk modulus, change evidently as the size is smaller than the critical thickness and the change tendency is tightly controlled by the surface atom composition. On the other hand, as the nanofilm size exceeds the critical one, the calculated values of the elastic properties are almost independent of the film thickness. Relatively, the bulk modulus magnitude of the nanofilm is apparently larger than that of the corresponding bulk material. Finally, the inherent mechanisms of the size impacting on the elastic properties of the B 2- NiAl nanofilm have been discussed in more detail. The strengthening effect of the bulk modulus results from the smaller multilayer relaxation of the interlayer distance as compared to those of the bulk materials.

Abstract:

The development and use of nanotechnology in the food industry (nanofood) have grown steadily. While visions for nanofood suggest that the applications will improve quality and safety, they are also controversial for several reasons including potential health risks coupled with difficulty in assessing low-dosage nanoparticle risks as well as values-based objections. In recent years, debate over nanofoods has sparked inquiry into factors that predict public attitudes and purchase intentions. Such studies have investigated the roles of demographics and sociographics, value predispositions toward science and technology, preferences for natural products, trust in regulatory agencies, scientific knowledge, and media attention. This study assesses the role of each of these factors in shaping public attitudes toward nanofood and improves the predictive models by evaluating concepts from protection motivation theory. We find that incorporating threat and coping appraisals provides the best predictive models of public attitudes and intention to purchase nanofood products.

Abstract:

The removal of TCE by nanofer zero valent iron (nanofer ZVI) coated with tetraethyl orthosilicate (TEOS) in the presence of Cu(II) at different environmental conditions was studied. The kinetics of TCE degradation by nanofer ZVI was determined. At a dosage of 10 mg of nanofer ZVI, almost 63% of TCE was removed, when Cu(II) and TCE were present. It contrasts with 42% degradation of TCE in the absence of Cu(II). SEM/EDS images indicated that Cu(II) is reduced to formCu0and Cu2O. These formations are considered to be responsible for enhancing TCE degradation. Direct reduction involves hydrogenolysis andβ-elimination in the transformation of TCE, while indirect reduction involves atomic hydrogen and no direct electron transfer from the metal to reactants. The reduction of activation energy was also noted indicating that the rate limiting step for TCE degradation in the presence of Cu(II) is surface chemical reaction rather than diffusion. Most of iron present in nanofer ZVI get dissolved causing the generation of localized positive charge regions and form metal chlorides. Local accumulation of hydrochloric acid inside the pits regenerates new reactive surfaces to serve as sources of continuous electron generation. No significant effect of TCE was noticed for Cu(II) sequestration.

Abstract:

The integration of engineered nanomaterials (ENMs) in the food and agriculture industry is now common and rampant among giant food manufacturers to enhance the quality, functionality, and physicality of food products. However, consumers have not been consulted and informed on the use of ENMs in food despite various potential safety and health risks associated with oral exposure of ENMs illustrated from scientific studies. In the European Union, the food law was amended to include provisions on nanotechnology after conducting a public consultation to explore public awareness and perception of nanotechnology. In the absence of a specific regulatory framework for nanofood in Malaysia, this study aims to analyse consumers’ awareness and knowledge of nanofood. The result from the study serves as an invaluable input to the regulatory authority in framing any regulatory reform to regulate nanofood. A survey was conducted using a closed-ended questionnaire distributed online. The result indicates that the awareness and understanding of nanofood are still lacking and not satisfactory.
