Abstract:
Aim: We report our single-center experience with the retrieval and replacement of the chronically implanted Micra transcatheter pacing system (TPS). Material and Methods: We included 6 patients with an implanted the Micra TPSs who subsequently underwent transvenous method of retrieval at our institution. The indication for device retrieval was pacemaker syndrome in two patients, battery depletion in three patients, and need for upgrade to biventricular pacing in one patient. Results: After an implantation duration of 555 ± 373 days, the overall retrieval success rate was 83.3%, 5 of 6 patients. No procedure-related adverse device events occurred. In the single patient with unsuccessful retrieval, intracardiac echocardiography revealed that the Micra TPS was embedded within the cardiac wall and surrounding tissue. After retrieval, four patients received a new Micra TPS. Conclusions: Late retrieval of an implanted Micra TPS was safe and feasible, which indicates the possibility for their safe and elective replacement with a new leadless pacing device.

Abstract:
Abstract Aims Leadless pacing has become an alternative approach for patients requiring a single-chamber pacemaker. Conventionally, leadless Micra Transcatheter Pacing System (TPS) pacemakers are implanted via a right femoral venous access. However, due to various reasons, a left-sided femoral venous approach may be necessary. We hypothesized that a left-sided femoral venous approach is as safe and effective when compared with a right-sided approach. We assessed indications, procedural characteristics, safety and mid-term outcomes of Micra TPS implantation via a left femoral venous approach when compared with the conventional right-sided approach. Methods and results In this retrospective single-centre analysis, 143 consecutive patients undergoing Micra TPS implantation were included. 87% (125/143) underwent Micra TPS implantation via a right, and 13% (18/143) via a left femoral venous access. The mean age at implantation was 79.8 ± 7.5 years. Acute procedural success, mean procedure and fluoroscopy times as well as device parameters at implantation and follow-up (mean 15 ± 11.5 months) were similar between the two groups. Five major complications (3.5%) were encountered, all using a right-sided approach. After a transfemoral TAVI procedure, left femoral venous access was used in 42% of cases when compared with 8% in the remaining population (P = 0.003). Conclusions A left femoral venous access for Micra TPS implantation is safe and effective with an excellent implantation success rate similar to a conventional right femoral venous access without longer implantation and fluoroscopy times. The most frequent reason for choosing left vs. right femoral venous access was a previous transfemoral TAVI procedure.

Abstract:
This case report records a novel indication for implantation of a leadless Micra transcatheter pacing system (TPS). We present the case of a 66 year-old man suffering from Parkinson’s disease who was admitted to the hospital with a third degree heart block which developed into cardiac arrest. Due to two previously implanted deep brain stimulation devices, which occupied the space where a standard pacemaker impulse generator would be located, placement of a standard pacemaker was deemed inappropriate. The patient was therefore qualified for a leadless Micra TPS implantation. The procedure was uneventful and the patient was discharged after undergoing extensive treatment of an underlying fungal pneumonia.

Abstract:
Atrioventricular nodal conduction abnormalities are common after open heart surgery and more so during or after valve surgery. The incidence of atrioventricular (AV) block after tricuspid valve (TV) surgery is higher than what is observed following coronary artery bypass surgery or left sided valve interventions due to the proximity of the TV annulus to the AV node and hence requirements for cardiac pacing are high. However, the mechanical interference between pacing leads and TV leaflet mobility and coaptation can result in regurgitation rendering such an approach counterintuitive. We report a case of Micra Transcatheter pacing system (TPS) implant under direct visualization at the time of tricuspid valve surgery performed via a right mini-thoracotomy approach.

Abstract:
People over 65 years old account for almost one fifth (19%) of the European population. A percentage of the oldest old in this group also increases. Patients over 80 years old are burdened with a number of comorbidities with the lead of cardiovascular diseases (CVD). An aging organism creates demanding conditions for pacemaker implantation and surgery in general. We report a case of a 102-year old patient with tachycardia-bradycardia syndrome and syncope who has had MicraTM Transcatheter Pacing System (Micra TPS, Medtronic, Minneapolis, MN, USA) implantated.

Abstract:
Background and objectives: Leadless pacemakers are less invasive but are as effective as conventional pacemakers and are increasingly implanted in elderly patients. However, the implantation procedure is sometimes challenging in patients with abnormal anatomy, particularly those with an enlarged right heart. We aimed to determine the right heart parameters that were associated with longer procedure times for leadless pacemaker implantation. Materials and Methods: Among 19 consecutive patients in whom Micra leadless pacemakers (Micra TPS, Medtronic, Minneapolis, MN) were implanted, the diameter and area of both the right atrium and right ventricle were measured by transthoracic echocardiography before the procedure. The right heart parameters that were associated with a procedure time > 60 min were investigated. Results: In the 19 patients (median 81 years old, 10 male) who underwent implantation of the Micra system, 6 (32%) required a procedure time > 60 min. Among the baseline right heart echocardiographic parameters, right atrial diameter and area were significantly associated with a procedure time > 60 min (odds ratio 11.3, 95% confidence interval 1.09–1.17, p = 0.042; and odds ratio 1.57, 95% confidence interval 1.05–2.34, p = 0.029, respectively) at a cutoff of 4.0 cm and 17.0 cm2, respectively. Conclusions: Patients with an enlarged right atrium may not be good candidates for leadless pacemakers given the longer procedure time, and conventional pacemakers should perhaps be recommended as an alternative.

Abstract:
In questa tesi viene descritta l'evoluzione dei pacemaker, dal primo introdotto nel 1958 fino ai giorni nostri con l'arrivo di tecnologie sempre più efficienti e miniaturizzate. In particolar modo per chi soffre di bradicardia è stato introdotto in commercio dal 2015 il pacemaker più piccolo al mondo: il Micra TPS (Transcatheter Pacing System). Questo pacemaker monocamerale viene inserito nel ventricolo destro del paziente attraverso un sistema di ancoraggio, permettendo una miglior praticità per il paziente rispetto al classico pacemaker "scatola e filo". I vantaggi principali di questo pacemaker sono: dimensioni,durata batteria,materiali e compatibilità con applicazioni per smartphone e tablet.

The need of producing polymeric artifacts increasingly powerful and versatile but which have increasingly lower biodegradation times motivates the scientific community to seek combinations of natural and synthetic polymers in order to meet both aspects. The manufacture of the blend LDPE/TPS Starch / Chitosan aims to go against that objective. The biodegradation occurs mostly in the soil. Trying to understand the dynamics of the biodegradation process in soil, this paper monitored the effects caused by deposition of the blend, analyzing different parameters, such as organic carbon, organic matter and microbial carbon, indicating levels of soil quality.The blends were prepared with different concentrations of chitosan, with values set to 0, 7, 5 and 15% of total mass and buried in pure soil and soil treated with humus. The analysis periods were 10, 40, 70, 100 and 130 days, with samples being exposed to the environment. Infrared analysis were performed using Fourier transform, X-ray diffraction, scanning electron microscopy with spectroscopy dispersive energy before and after biodegradation mass loss, after the biodegradation process of the blends. Organic carbon, organic matter, microbial carbon, pH and moisture in the soil.The results obtained after analysis in blend showed that with the passage of time, the biodegradation process happened, considering that carbon levels dropped considerably and oxygen were increased in accordance with the EDS analysis. The FTIR analysis confirmed this fact by showing that there was an intese oxidative process, especially in the initial 70 days in all samples. The X-RD analysis showed that there was a variationin crystallinity, but always with a decrease of this paramenter. The weight loss was also significant and progressive in all samples. Soil results showed that the same is resilient and can recover its characteristics during the biodegradation process. At the beginning of the experiment, especially in the first 40 ays, all evaluated paramenters declined considerably, but returned to baseline levels and maintained these values by the end of the experiment. Experimental design was made and it showed that none of the dependent variables influenced the biodegradion process.
A necessidade de produzir artefatos polim?ricos cada vez mais vers?teis e ?performantes? e que apresentem caracter?sticas de biodegrada??o cada vez mais acentuadas tem motivado a comunidade cient?fica a buscar combina??es entre pol?meros sint?ticos e naturais com o objetivo de atender esses aspectos. O desenvolvimento de blendas de polietileno de baixa densidade/amido termopl?stico/quitosana (PEBD/TPS/Q) e de amido termopl?stico/quitosana (TPS/Q) visou ir de encontro a tal objetivo, procurando entender a din?mica do processo biodegradativo no solo. O presente trabalho acompanhou os efeitos causados pela deposi??o dessas blendas, analisando diferentes par?metros, como carbono org?nico total, massa org?nica total e carbono de biomassa microbiana, que indicam n?veis de qualidade do solo, al?m da perda de massa ap?s cada per?odo de biodegrada??o. As blendas de PEBD/TPS/Q e TPS/Q foram preparadas com diferentes concentra??es de quitosana, com valores definidos em 0, 7,5 e 15% da massa total e enterradas em solo puro e solo tratado com h?mus. Os per?odos de an?lise de biodegrada??o foram de 10, 40, 70, 100 e 130 dias, com as amostras sendo expostas ao ambiente. As blendas foram analisadas por espectroscopia de infravermelho com transformada de Fourier (FTIR), difra??o de raios-X (DRX), microscopia eletr?nica de varredura com espectroscopia de energia dispersiva (MEV/EDS), e quanto a perda de massa, antes e ap?s o processo de biodegrada??o. Tamb?m foram realizadas an?lises de carbono org?nico total, massa org?nica total, concentra??o de carbono de biomassa microbiana, pH e umidade dos solos utilizados. Os resultados comprovaram o processo biodegradativo das blendas com o passar do tempo, tendo em vista a diminui??o dos n?veis de carbono e aumento consider?vel dos n?veis de oxig?nio das blendas de PEBD/TPS/Q, de acordo com as an?lises de FTIR e EDS, e total biodegrada??o das blendas de TPS/Q. As bandas de FTIR comprovaram a ocorr?ncia do processo oxidativo, principalmente nos 70 dias iniciais, nas amostras de PEBD/TPS/Q. As an?lises de DRX mostraram que houve uma varia??o da cristalinidade, com a tend?ncia de diminui??o deste par?metro. A perda de massa tamb?m foi consider?vel e progressiva para todas as amostras. Os resultados de an?lise das amostras de solo mostraram o poder de recupera??o da atividade microbiana dos mesmos (resili?ncia) durante o processo biodegradativo. No per?odo inicial do experimento, em especial nos primeiros 40 dias, todos os par?metros avaliados sofreram decaimento de seus valores, por?m retornaram aos patamares iniciais e mantiveram esses valores at? o final do experimento. O planejamento experimental realizado mostrou que nenhuma das vari?veis independentes influenciou no processo de bioatividade do solo.

Abstract:
Micro-affordance effects have been reported for several different components of the reach-to-grasp action during both on-line and off-line visual processing. The presence of such effects represents a strong demonstration of the close relationship between perception, action, and cognition. In this thesis 7 experiments are described, which investigate different aspects of that relationship, with particular attention on the nature of object representations. In 5 behavioural experiments as well as in 1 Transcranial Magnetic Stimulation (TMS) experiment a stimulus-response compatibility paradigm is employed to examine the presence of micro-affordance effects arising during language processing of object names. The power and precision component of the reach-to-grasp action is investigated in relation to the compatibility of an object for grasping with either a power or a precision grasp. Overall, the results of the experiments discussed in the present thesis suggest that: a) object representations activated during language processing of object names are able to potentiate actions arising from the component of the reach-to-grasp action under investigation; b) such representations might be more semantic or „propositional‟ than depictive in nature, therefore more related to stored semantic knowledge of the object and its associated actions than to its detailed visual properties; c) this semantic information about objects seems to be automatically translated into specific motor activity, even in the absence of any intention to act; d) finally, such semantic, non-visual motor potentiation seems to be rapid and relatively short lived.

Abstract:
De nombreuses mesures cosmologiques et astrophysiques tendent à montrer que notre galaxie serait englobée par un halo de matière sombre non-baryonique. La détection directionnelle vise à mesurer la direction du recul nucléaire issu d'une interaction avec une particule de matière sombre. Cela permettrait de mettre en évidence la forte dépendance angulaire de la distribution de reculs due à la rotation du système solaire autour du centre galactique. Cette thèse aborde la détection directionnelle par une approche multi-thématique : phénoménologie, expérimentale et analyse de données. L'objectif des études phénoménologiques est de montrer l'apport d'un détecteur directionnel en terme de recherche de matière sombre. Grâce au développement de méthodes statistiques dédiées, on montre qu'un détecteur tel que celui proposé par la collaboration MIMAC, devrait permettre de découvrir la matière sombre avec une grande significance jusqu'à des sections efficaces 2 à 3 ordres de grandeur en dessous des limites actuelles. La mise en place d'une méthodologie d'analyse de données directionnelles constitue un second objectif de cette thèse car la reconstruction 3D des traces mesurées est un point clef de cette nouvelle stratégie de détection. On présente ainsi une nouvelle méthode d'analyse basée sur une approche par vraisemblance, permettant d'optimiser l'estimation des paramètres de chaque événement mesuré: position dans le détecteur et direction. Dans le cadre de la discrimination du bruit de fond électronique, on a mis en place une étude basée sur la topologie de la trace et utilisant une analyse par arbres de décision boostés qui nous permet d'obtenir des facteurs de rejet environ 20 fois supérieurs à ceux obtenus avec des analyses séquentielles. Du point de vue expérimental, on présente une méthode originale de la mesure de vitesse de dérive des électrons permettant d'obtenir des incertitudes de l'ordre du pourcent et de contraindre simultanément les coefficients de diffusion longitudinale. On termine enfin sur l'analyse des données obtenues auprès du champ de neutrons AMANDE permettant de valider la stratégie de détection du projet MIMAC.

Abstract:
Le collisionneur linéaire international (ILC) est prévu pour être le prochain grand projet de la physique des hautes énergies. ILC est proposé avec deux détecteurs, International Large Detector (ILD), et Silicon Detector (SID). Cette thèse s’est déroulée dans le cadre de l'ILD. L'un des principaux composants du détecteur ILD est la chambre à projection temporelle (TPC). Cette thèse se concentre sur le développement de la lecture de la TPC, basée sur l'intégration des détecteurs de gaz Micro-pattern (Micromegas) et de puces CMOS pixels ("Timepix"). Ce nouveau type de dispositif est appelé "Ingrid". Les exigences principales pour "Ingrid" sont d’atteindre la sensibilité aux électrons uniques et d’obtenir une très haute résolution spatiale (~ 30 µm). Avec une TPC, on reconstruit les traces en utilisant le profil 2D des charges sur la plaque a l’extrémité de la TPC et la troisième coordonnée est dérivée du temps de dérive. Dans le cadre de cette thèse, une mini-TPC a été construite a Saclay dans le but de tester plusieurs prototypes de détecteurs "Ingrid". En outre, un système compose de 8 puces nommé "Octopuce" a été construit pour développer des algorithmes de reconstruction de traces. Nous avons effectué plusieurs mesures à l'aide de source radioactive à Saclay. Par ailleurs, de grands modules ont été testés avec un prototype de grande TPC (LP) sur un faisceau de test à DESY. Les résultats obtenus avec deux modules différents ont été présentés et les résultats sont en bon accord avec la prédiction théorique. La présence de la matière noire fournit une bonne indication d'apparition de nouveaux phénomènes a proximité de l'échelle électrofaible, et l'hypothèse populaire d’existence des WIMP doit être testé. Comme les couplages des WIMP aux différentes espèces de particules du modèle standard sont a priori inconnus, la recherche de la production de WIMP en collisions e+e- est complémentaire à la production dans les collisions pp ou a la détection directe de WIMPs primordiaux par leur diffusion sur des nucléons. Dans ce travail, nous étudions possibilité de découverte (ou l'exclusion) de production de paires de WIMPs avec l’ILC. Dans ce processus, un unique photon est rayonne dans l'état initial et une énergie manquante est requise. Nous montrons que l’ILC peut découvrir cette signature, même si l'annihilation en paires électron-positon contribue faiblement au taux d’annihilation de la matière noire dans l'univers primordial. Nous avons traduit la sensibilité en terme d’échelles de masse pour différents types d’opérateurs effectifs et montré que la masse et les couplages des WIMPs peuvent être mesurés avec une précision de l’ordre de 1% si leur détection est avérée. En outre, des études de production de WIMPs avec l’ILC sont complémentaires aux études avec des états finaux mono-X au LHC, car ils testent le couplage WIMP-lepton. Au LHC, le couplage WIMP-proton est testé a une l'échelle de 1 TeV. Avec l’ILC, en utilisant une luminosité intégrée de 500 fb⁻¹, une énergie dans le centre de masse de √s = 500 GeV et avec des faisceau non polarisés, une limite pour l’échelle sur l'interaction de contact Λ de l’ordre de 2 TeV est accessible. De plus, les configurations de polarisation appropriées permettent d'améliorer la sensibilité pour les recherches de matière noire à l’ILC, en supposant que le couplage des paires de WIMP aux électrons et aux positons dépend du choix de l'opérateur
The International Linear Collider (ILC) is planned to be the next major project in the High Energy Physics. ILC is proposed to have two detectors, namely International Large Detector (ILD), and Silicon Detector (SiD). This thesis is done in the framework of the ILD. One of the main components of the ILD detector is the Time Projection Chamber (TPC). This PhD thesis concentrates on the development of TPC readout, based on integration of the Micro-pattern gas detectors (Micromegas) and CMOS pixel chips ("Timepix"). This new type of device is named "InGrid". Main requirements for "InGrid" is to achieve sensitivity to single electrons and a very high spatial resolution (~30 μm). In TPC one reconstructs tracks using 2D-charge profile on the TPC endplate and the third coordinate is derived from the drift time information. In Saclay mini-TPC was built. Using this mini-TPC, several prototype "Ingrid" detectors have been tested in the course of this PhD. In addition, 8-chips system named “Octopuce” was built to develop track reconstruction algorithms. We have performed several measurements using laboratory radioactive source in Saclay. In addition, the large modules were tested at a Large TPC Prototype (LP) in a test beam area at DESY. Results with two different modules were presented. Obtained results well agreed with theoretical prediction. The existence of Dark Matter provides a strong indication for the appearance of new phenomena near the electroweak scale, and the popular WIMP hypothesis is out there to be tested. Since the couplings of WIMPs to different species of Standard Model particles are a priori unknown, the investigation of WIMP production in e+e- collisions is fundamentally complementary to production in pp collisions or direct detection of primordial WIMPs scattering on nucleons. In this work we investigate the discovery (or exclusion) reach of the ILC based on the production of a pair of WIMPs, which recoils against an energetic photon from initial state radiation. We show that the ILC can discover this signature even if annihilation to electrons provides only a small fraction of the total dark matter annihilation rate in the early universe. We translated the sensitivity into mass scales of various effective operators and showed that the WIMPs mass and couplings can be measured at the percent level in case of an observation. Furthermore, WIMPs studies on ILC are complementary to current LHC in the mono-X final states, because they test WIMP-lepton coupling. LHC studies WIMP-proton coupling at the scale of 1 TeV. ILC could reach limits up to 2 TeV on the contact interaction scale Λ for the vector operator by using an integrated luminosity at 500 fb⁻¹, at the center-of-mass √s = 500 GeV with unpolarized beams. Moreover, proper polarization configurations allows to improve sensitivity for the Dark Matter searches at the ILC, assuming WIMPs pair couple differently to electron and positron for different operators

Abstract:
A área de microfabricação de dispositivos de interesse em química analítica tem se expandido muito ao longo dos últimos anos. Uma série de produtos e processos tem sido proposta, tendo como base as tecnologias da área de microeletrônica. Muito destes processos são bastante sofisticados, estando além das necessidades para produção de alguns dispositivos relativamente simples e que são bastante úteis para a química analítica. Este é o caso, por exemplo, dos microcanais para implementação de sistemas eletroforéticos ou micro sistemas em fluxo. Neste contexto, surge a proposta deste trabalho, qual seja desenvolver processos e produtos de interesse nesta área. Esse objetivo foi alcançado pelo desenvolvimento de dois processos: um para produção de microcanais em resina de poliéster através de moldagem e outro de corrosão de vidro utilizando toner de impressora laser como resiste. O primeiro partiu de fotolito para produção de molde em silício através de processo de corrosão por plasma de SF6. Peças de resina de poliéster isoftálica são produzidas por polimerização sobre este molde. Para garantir a desmoldagem não traumática e boa reprodução de detalhes, foi incorporado óleo de silicone durante a preparação da resina. Com este procedimento, foi possível obter canais com 14,0 µm de profundidade e irregularidades superficiais de 1,4 µm para um molde com 15,3 µm de elevação e 0,5 µm de irregularidades superficiais. Com o uso de uma manta flexível de silicone como contraparte, foi possível gerar microcanais cuja altura foi avaliada como sendo da ordem de 5 a 7 µm. Esta avaliação foi conseguida através de medida de condutância após o preenchimento do microcanal com solução de KCl. No segundo processo, toner de impressora laser foi utilizado como resiste para corrosão de vidrO. O layout era diretamente impresso sobre papel aditivado com maltodextrina ou papel utilizado como suporte para etiquetas autocolantes através de uma impressora HP LaserJet 6L com resolução de 600 dpi. Após a transferência térmica da imagem para lâminas de vidro alcalino de 1,0 mm de espessura, a corrosão em ácido fluorídrico permitiu obter canais com 7,1 µm de profundidade e irregularidades de 1,0 µm. Embora este segundo processo apresente desvantagens com relação à resolução tanto no plano da lâmina como na profundidade do canal, quando comparado ao primeiro, deve-se ressaltar a extrema simplicidade, rapidez e baixo custo do processo que deve ser interessante para a produção de protótipos. Já para o primeiro processo, destaca-se a adequação à produção em pequena escala de dispositivos microcanais de baixo custo.
Several processes and products have been proposed to build and use microstructures for chemical purposes. Most of these processes were adapted from microelectronic technologies, which resulted in products with excellent resolution and quality. However, there are some devices that could be generated by simpler and rougher processes. In this work, two processes were developed in order to allow producing simple devices based on microchannels. The first process is a method to produce polyester based devices. A conventional microelectronic process was used to produce a silicon matrix. This matrix was used to produce blocks of isophthalic resin by in situ polymerization. The best results were obtained by adding 1 % (w/w) silicone oil during the polyester resin preparation. This additive improves the mold relief and the smoothness of the device surface. Channels 14.0-µm depth and roughness of 1.4 µm were obtained with a mold with structure height of 15.3 µm and roughness of 0.5 µm. A flexible sheet of silicone allows forming enclosed microchannels with depth of 5-7 µm. This dimension was evaluated by conductance measurement after filling the channel with KCl solution. A process for glass corrosion, using laser printer toner as resist, was proposed. In this method, the layout is printed over a special sheet of paper using a HP LaserJet 6L laser printer. The paper is used to transfer the toner to a soda-lime glass lamina by a thermic process. Hydrofluoric acid solution was used to promote the selective glass corrosion. Channels 7.1-µm depth and roughness of 1.0 µm were obtained. Although this second method does not give the saroe resolution and aspect ratio as the first one, it is suitable to easy and fast prototyping. Gn the other hand, the first method is suitable for low-cost production of devices in small scale.

Abstract:
Neste trabalho são apresentados processos de microfabricação de estruturas contendo microcanais e sistemas de manipulação hidrodinâmica e eletroosmótica de fluídos. Foram desenvolvidos processos de microfabricação utilizando toner sobre poliéster, toner sobre vidro, toner como resiste, além de métodos alternativos de perfuração de lâminas e selagem de microestruturas em vidro, desenvolvimento de microestruturas para eletroforese capilar e espectrometria de massas com ionização por eletronebulização. A caracterização dos materiais e processos permitiu uma ampla visão das potencialidades e alternativas dos processos de microfabricação, tendo sido demonstrado que os dispositivos produzidos em toner-poliéster são quimicamente resistentes às substâncias tipicamente utilizadas em eletroforese capilar. Neste trabalho, um detector condutométrico sem contato foi implementado em microestruturas de toner-poliéster e a separação eletroforética de alguns metais alcalinos é demonstrada. A microestrutura foi projetada no formato padrão em cruz, tendo o canal de separação 22 mm de comprimento, 12 µm de profundidade e largura típica. A cela condutométrica foi construída sobre o canal de separação utilizando-se fita adesiva de cobre (1 mm de largura) como eletrodos. O sinal aplicado na cela foi de 530 kHz e 10 Vpp . A separação de K+, Na+ e Li+ na concentração de 100 µmol L-1 foi efetuada em torno de 0,8 min, utilizando-se 1 kV como potencial de separação. Foram desenvolvidos microchips para análise por espectrometria de massas com introdução de amostra por eletronebulização, sendo determinado cluster do íon cloreto em concentração de 1 mmol L+. Também solução com 1 mmol/L de glucosamina em água/metanol 1: 1 (v/v), sob corrente de 100 nA gerou sinal estável e livre de descarga corona. Utilizando detecção amperométrica, obteve-se eletroferogramas mostrando a separação de iodeto (10 mmol L-1) e ascorbato (40 mmol L-1) em potencial de separação de 4,0 kV (800 V cm-1 potencial de detecção de 0,9 V (vs. Ag/AgCI), injeção com 1,0 kV/1°s, tampão borato de sódio 10 mmol L+ com CTAH 0,2 mmol L-1, pH 9,2. Obteve-se eficiência de 1,6.104 pratos/m e foi possível obter limites de detecção de 500 nmol L-1 (135 amol) e 1,8 µmol L-1 (486 amol) para iodeto e ascorbato, respectivamente. O processo de fabricação utilizando toner como material estrutural para microchips em vidro foi bem estabelecido, assim como os modos de detecção fotométrico e condutométrico foram demonstrados. Foram obtidos eletroferogramas par detecção condutométrica sem contato de solução 200 µmol L-1 de K+, Na+ e U+, em tampão histidina/ácido lático 30 mmol L-1 9:1 (v/v) água:metanol, injeção eletrocinética de 2,0 kV/5,0 s, potencial de separação de 1 kV, 530 kHz de frequência e tensão de 2,0 Vpp. Também foi implementado um sistema de detecção fotométrico para microchip operando em 660 nm, tendo sido utilizado para a detecção de azul de metileno 1,0 mmol L-1 em tampão de corrida de barato de sódio 20 mmol L-1 (pH 9,2), com o detector posicionado a 40 mm do ponto de injeção e com injeção eletrocinética a 2,0 kV por 12 s com picos bem resolvidos em menos de 1 min.
Microfabrication processes and devices for hydrodynamic and electroosmotic manipulation were developed based on toner-polyester, toner-glass and toner-as-resist techniques. Additionally, techniques to perforate glass slides and sealing of glass devices were introduced. Microdevices for capillary electrophoresis and electrospray for mass spectrometry were developed using these techniques. The characterization of the materiais and the processes demonstrated that the devices obtained by the toner-polyester process are compatible with the media used for capillary electrophoresis. The detection of alkaline ions with capillary electrophoresis with contactless conductivity detection was demonstrated. The typical cross shape microstructure was designed with a 22-mm long and 12-µm deep separation channel. The conductivity cell was implemented with 1-mm wide adhesive copper stripes. The applied signal was 530kHz and 10Vpp . The separation of 100µmo1L-1 K+, Na+, and Li+ was accomplished in 0.8 min under a voltage of 1 kV. Another toner-polyester microchip was developed to demonstrate its usefulness for electrospray/mass spectrometry. Solutions of 1 mmol L-1 potassium chloride and 1 mmol L-1 glucosamine in water/methanol 1:1 (v/v) were introduced with stable current of 100 nA without corona discharge. Capillary electrophoresis with amperometric detection was also demonstrated. The separation of iodide (10 mmol L-1) and ascorbate (40 mmol L-1) was carried out at 4.0 kV (800 V cm-1) with detection potential of 0.9 V (vs. Ag/AgCl), electrokinetic injection at 1.0 kV/10 s, running buffer of sodium borate 10 mmol L-1 with CTAH 0.2 mmol L-1 , pH 9.2. The efficiency was 1.6.104 plates/m and the limits of detection were 500 nmol L-1 (135 9mol) and 1.8 µmol L-1 (486 amol) for iodide and ascorbate, respectively. The toner-glass process was proposed and conductivity and photometric detections were demonstrated for the devices generated by this new technique. The separation of 200 pmol L-1 K+, Na+, and Li+ was achieved in buffer histidine/lactic acid 30 mmol L-1 water/methanol 9: 1 (v/v), electrokinetic injection at 2.0 kV/5.0 s, separation potential of 1 kV, and contactless conductivity detection at 530 kHz and 2.0 Vpp. The photometric detection of methylene blue at 660 nm was carried out in sodium borate 20 mmol L-1 (pH 9.2).

Abstract:
The Thin Plate Splines (TPS) theory is modified and employed in the reconstruction of 2D 1/2 unfolded micro-topographical surfaces. The modified TPS allows the reconstruction of MEMS structures based on sampled digital elevation model (DEM). The developed algorithms are implemented in MATLAB and applied to restore bad samples, enhance surface reconstruction, and compensate for surface irregularities for micromachining purposes. In addition, the restored surface reveals the scale components of the real surface (roughness, waviness and form). The irregularity of meso, micro and nano surfaces is then characterized into slope, curvature, strike, dip, azimuth and energy surfaces. It is concluded that the simplicity, differentiability of TPS and roughness components relaxation make the proposed theory advantageous on reconstruction and characterization of micro surfaces for a variety of applications.

Abstract:
The mixing of two fluids is important in enhancing chemical reactions in a micro TAS. Some devices or methods are needed to enhance the mixing, because the Reynolds number is very low, on the order of 1. In the present research, we studied the possibility of using micro-bubble emission boiling. A heater made of a platinum wire of 30 micrometer was installed in a Y-shaped micro-channel whose cross sectional area was 2 mm × 0.5 mm. The heater was directly powered by electric current up to 1.5 A. The maximum heat flux was 7.47 MW/m2, which was well above the burnout heat flux. The subcool was 80 degrees and the velocity of fluid (colored water) was changed from 0.5 to 2.0 mm/s. When micro-bubble emission boiling occurred, the mixing was improved drastically. The mixing efficiency reached above 90% at v = 2.0 mm/s and q = 7.47MW/m2. In contrast, the mixing efficiency was poor in the case of normal nucleate boiling. The effect of the mixing chamber was also examined.
