Der Anteil von auf Proteinen basierenden Arzneimitteln am Arzneimittelmarkt nimmt stetig zu. Hierbei handelt es sich häufig um monoklonale Antikörper, welche zur Behandlung von Autoimmun- und Krebserkrankungen eingesetzt werden. Da es sich um hoch potente Arzneimittel handelt ist es wichtig, sie während aller Herstell…
The study sought to bring a solution to the slow and tedious process of knotting abaca (Musa textiles Nee) which is still processed by hand by a large number of abaca weavers and farmers. “Tinagak” is the local term for knotted Manila hemp, and is the basic component in the production of “sinamay” or dyed and stiffene…
Tout au long du siècle dernier, l’électronique s’est révélé être un progrès technologique majeur, et ses applications sont tellement nombreuses qu’elles ont envahi notre vie de tous les jours. De par leurs propriétés bien spécifiques, les semi-conducteurs organiques représentent une remarquable alternative aux matéria…

The behavior of water droplets on copper and aluminum surfaces has been examined in this work.This study reports a simple technique to move water droplets on hydrophobic copper surfaces containing a hydrophilic aluminum background.The copper is rendered hydrophobic using a self-assembled monolayer that has a higher se…
Ce travail avait pour buts d'évaluer la responsabilité des processus de diffusion, effusion et ionisation dans la transformation atome-ion, de mieux comprendre le comportement temporel des dispositifs ISOL, et d'en faire bénéficier les développements de systèmes de production ISOL. Ces buts ont été en partie atteints…
This thesis is a comparative experimental and theoretical work focused on the mechanical properties of Bombyx mori silk on macroscopic and molecular levels. We did study the response of silk to a mechanical perturbation by monitoring changes of the microscopic structure in the crystalline regions as well as the molecu…
This work deals with structural and electronic properties of trihydroborane -carbonyl BH3-CO as a donor-acceptor molecular system. B3LYP density functional theory was employed with various basis sets to calculate some structural and electronic properties for this system. The calculations include the bond length and an…
We report a new strategy to remove the reflections resulted from the finite embedded transformation-optical design by proposing an impedance-tunable coordinate transformation, on which the functions of impedance coefficients can be derived in the original space without changing the refractive index. Based on the new a…
Sven Behrens presented a lecture at the Nano@Tech Meeting on December 10, 2013 at 12 noon in room 1117 of the Marcus Nanotechnology Building.
Intravenous infusion is a necessary mode of delivery for many pharmaceuticals currently on the market or undergoing clinical trials. The technique of prolonged intravenous delivery in conscious, free-moving animal models has broadened the opportunity to study and evaluate the safety and efficacy of these therapeutic p…
Moderne Kraftwerke sind mit automatischen Synchronisationseinrichtungen ausgestattet. Daher gehört die Fehlsynchronisation zu den seltenen Störfällen. Bei Versagen der Automatik zählt sie jedoch zu den schwersten Störfällen. Sie kann zu schweren Schäden am Generator, an den Turbinen und am Blocktransformator führen, w…
Neutron activation of nanoparticles (NPs) can be a valid method to create radioactive NPs for biological and environmental tracers studies in a way that permits to overcome problems of high natural background of chemically equivalent materials in such matrices. Activation of NPs by neutron flux is mainly performed by…
Flexible powdered alloy sheets of different compositions were prepared by tape casting method , and the coating was prepared on the surface of 45 steel by hot pressing sintering .The microstructure and properties of the sintered layer was studied by using optical microscopy ,scanning electron microscopy and EDS .The e…
Методом монокристального рентгеноструктурного анализа исследованы два образца минерала мариинскита и установлены их формулы: Сr1.43Al0.64Be0.9O4 (образец 1) и Сr1.32Al0.74Be0.9O4 (образец 2). Параметры ромбических ячеек соответственно равны: a = 4.487(1), b = 5.629(1), c = 9.732(2) A; a = 4.478(1), b = 5.620(1), c = 9…

Abstract In the present study, nanocrystalline diamond (NCD) nanowire films were synthesized on silicon substrates, using microwave plasma-enhanced chemical vapor deposition (PECVD) with a CH4/Ar/N2 gas mixture at moderate temperatures. The influence of nitrogen concentration on the formation of NCD was investigated.…
Методом монокристального рентгеноструктурного анализа с привлечением данных рентгеноспектрального микроанализа и спектроскопии комбинационного рассеяния уточнена кристаллическая структура карбонатсодержащего апатита альбидной ткани позднедевонских конодонтов рода Polygnathus (отряд Ozarkodinida) апатит-органического…
Membranes made of composite polymer material are widely employed to separate gas mixtures in industrial processes. These membranes have better performance than membranes consisting of polymer alone. To understand the mechanism and therefore aid membrane design it is essential to explore the penetrant transport in the…
High temperature deformation and dynamic recrystallization behavior of Cu-Cr-Zr-Ce alloy at 0.01-5 s-1 and 600-800 ℃ were performed on Gleeble-1500 D simulating machine .The results show that the flow stress increases with the increase of strain rate and decreases with the increase of deforming temperature .Considerin…
