Diacylglycerol lipase-alpha and -beta control neurite outgrowth in neuro-2a cells through distinct molecular mechanisms.

peer reviewedLe but de cet article est dâoffrir une approche de la philosophie derridienne et
de sa âpoliticitĂ©â Ă partir dâune enquĂȘte sur la spĂ©cificitĂ© de son geste philosophique,
formulé en termes de délinéarisation du corpus philosophique traditionnel. Il remet en
perspective cette pratique herméneutique non-linéaire avec le travail derridien sur la
photologie, lâembryologie (prenant position pour lâĂ©pigĂ©nĂ©tique contre le prĂ©-formisme) et la ligne graphique, montrant lâimportance de sa rĂ©ception de la philosophie post-kantienne pour la relecture derridienne de ces motifs. Il propose alors dâenvisager la philosophie derridienne comme la recherche dâune Ă©nergie renouvelable du sens
Ceramic Barrier Layers for Flexible Thin Film Solar Cells on Metallic Substrates: A Laboratory Scale Study for Process Optimization and Barrier Layer Properties
Flexible thin film solar cells are an alternative to both utilityâscale and building integrated photovoltaic installations.
The fabrication of these devices over electrically conducting lowâcost foils requires the deposition of dielectric
barrier layers to flatten the substrate surface, provide electrical isolation between the substrate and the device, and avoid
the diffusion of metal impurities during the relatively highâtemperatures required to deposit the rest of the solar cell device
layers. The typical roughness of lowâcost stainlessâsteel foils is in the hundredânanometer range, which is comparable
or larger than the thin film layers comprising the device and this may result in electrical shunts that decrease solar cell
performance. This manuscript assesses the properties of different singleâlayer and bilayer structures containing ceramics
inks formulations based on Al2O3, AlN or Si3N4 nanoparticles and deposited over stainlessâsteel foils using a rotogravure
printing process. The best control of the substrate roughness was achieved for bilayers of Al2O3 or AlN with mixed particle
size, which reduced the roughness and prevented the diffusion of metals impurities but AlN bilayers exhibited as well the
best electrical insulation propertiesPeer reviewe
