Surface chemical modifications are presented for supporting primary neurons in culture. The initial substrates for culture were glass and gold. The surface modifications were based on self assembled monolayer (SAM) approaches. Glass surfaces were initially modified by silanisation with either 3-aminopropyltrimethoxysi…
Lichtmikroskopie wird durch die Beugung von Licht auf eine Auflösung von etwa der halben Wellenlänge des Lichtes begrenzt. Neuere Methoden der Fluoreszenzmikroskopie umgehen diese Beugungsgrenze, indem die Position einzelner fluoreszierender Moleküle mit einer Genauigkeit bestimmt wird, die weit über der Auflösungsgre…
The comparative study of the influence of stitch length and fabric structure on the pilling, crease recovery and drape properties of 100% cotton, 50/50 and 67/33% polyester/cotton fabrics in interlock and single pique structures were studied. It was found that drape and fabric pilling increased with increase in stitch…
The repair of bone defects and fracture non-unions remain a challenge for clinicians. Current materials have limitations regarding quality, availability and there are long-term complications. Alternative graft materials, often in combination with growth factors have been investigated, but, poor retention of growth fac…
Le principe du controle non destructif par Flux de Fuite Magnetique (FFM) consiste a magnetiser une piece a controler par un champ magnetique intense et a detecter a l’aide d’un capteur magnetique les fuites des lignes de champ qui resultent de la presence d’un defaut dans la piece. Les methodes de controle FFM sont t…
We have theoretically and experimentally investigated the formation of both active and passive surface relief gratings on two kinds of photosensitive polymers: negative photoresist and azobenzene copolymer. The common mechanism of the structures formation was attributed to mass transport effect, which however pushes t…
The electrical properties of organic solar cells (OSC) have been investigated to understand the charge loss mechanisms impacting the over all efficiency. The power conversion efficiency of a solar cell is dependent upon the short-circuit current density (J SC ), open circuit voltage (V OC ) and the fill factor (FF). T…
The above article in the Journal of Biomedical Materials Research Part B: Applied Biomaterials, published online on 7 June 2013 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal Editor in Chief, Jeremy L. Gilbert, and Wiley Periodicals, Inc. The retracti…
The technological advances in areas such as automotive and aerospace industries require materials capable of withstanding demanding conditions. Surface treatments are effective tools to improve the surface properties of materials while preserving their bulk properties. Besides many conventional processes, laser treatm…
Single unit cell films of iron selenide (1UC FeSe) grown on SrTiO3 (STO) substrates have recently shown superconducting energy gaps opening at temperatures close to the boiling point of liquid nitrogen (77 K), a record for iron-based superconductors. Towards understanding why Cooper pairs form at such high temperature…
Combustion synthesis leverages the exothermic reaction between a fuel and an oxidizer to provide the energy needed to form crystalline refractory oxides. In many cases combustion syntheses are less energy intensive and require fewer processing steps than traditional ceramic oxide processes. However, the properties of…
The aim of this project is to develop a new class of orthopaedic implant materials that combine the excellent biocompatibility of pure titanium with the outstanding biomechanical compatibility of Ti-Ni-based shape memory alloys. The most suitable candidates for such a role are Ti-Nb-Zr and Ti-Nb-Ta near-beta shape mem…
Lipid nanoparticles (LNPs) are used to deliver siRNA to hepatocytes via endocytosis and subsequent endosomal release.With 99% of the LNPs taken up by the cell via endocytosis, only 1% of the siRNA is actually released into the cell cytosol.To improve the effectiveness of LNPs association with and disruption of endosom…
Existen multiples razones para abordar el estudio, la optimizacion y la mejora de las ecuaciones que rigen los procesos de la fluencia plastica en estado estacionario o en estados transitorios, tanto en su aspecto de ecuaciones de estado como de ecuaciones algebraicas constitutivas. Una de ellas, y no menos importante…
\n No presente trabalho foram estudados os fenômenos de encruamento e, principalmente, transformação de fases, recuperação e recristalização, presentes na liga U-7,5Nb-2,5Zr (Mulberry alloy) e no urânio não ligado. Realizou-se a fusão da liga por dois métodos: plasma (menor massa) e indução (maior massa). A caracteriz…
Au cours de ce travail de these, nous avons developpe un procede plasma-catalyse d'elimination de l'acetaldehyde en utilisant un processus diphasique couplant un catalyseur nano-structure et a plasma a la pression atmospherique. L’elaboration du catalyseur nanostructure a ete d'abord etudiee. Puis la performance de de…
La modélisation numérique des décharges plasma joue un rôle important dans la compréhension des mécanismes physiques ou chimiques ayant lieu dans les dispositifs assistés par plasma. Une grande partie de ces mécanismes est déjà prise en compte dans les codes actuels. En revanche, beaucoup d'entre eux ne permettent pas…
A principal contribuição para a exposição externa aos seres humanos provem da radioatividade natural presente em solos, principalmente do 40 K e das séries do 238 U e 232 Th.No presente trabalho foram determinadas as concentrações de atividade de 226 Ra (série do 238 U) , 232 Th e 40 K em amostras superficiais de arei…
This work is devoted to the study of interactions between fuel, flame and water droplets generated by water mist systems. It is completed by an extinction model development in FDS (Fire Dynamics Simulator) software, which is a CFD code widely used by the scientific and engineering communities. Knowledge on physical ph…
The socio-economic benefits anticipated with the use and production of nanomaterial and nanoparticles in consumer products are linked to the fulfillment of the requirement for sustainability during the whole material life cycle. Engineered nanoparticles (ENP) can be of environmental concern, both due to the possible h…
