Andean wetlands are characterized by their extreme environmental conditions such as high UV radiation, elevated heavy metal content and salinity. We present here the first study on UV tolerance and antioxidant defense of four Acinetobacter strains: Ver3, Ver5 and Ver7, isolated from Lake Verde, and N40 from Lake Negra…

Electromagnetic radiation of 1 - 10 THz range has been found at room temperature in a structure with a point contact between a ferromagnetic rod and a thin ferromagnetic film under electric current of high enough density. The radiation is due to nonequilibrium spin injection between the structure components. By estima…

The set of experimental data on the X-ray-excited luminescence and X-ray induced conductivity of ZnSe are compared to the data on the photoluminescence and photoconductivity. It is experimentally established that the current-voltage characteristics and the kinetics of phosphorescence and current relaxation depend on t…

While diverse fracture characteristics have been observed in liquid metal embrittlement (LME) depending on the solid-liquid metal pairs, the penetration of nanometer-thick liquid metal films along the grain boundary has been identified as one of the key mechanisms for embrittlement in many classical LME systems, such…

La microscopie à force atomique exploite les interactions entre une sonde et un échantillon. Les nanotubes de carbone représentent la sonde idéale, ils sont: fins, robustes, peu réactifs et ont un haut rapport d'aspect. L'utilisation à grande échelle des sondes à nanotubes de carbone passe par l'étude de leur comporte…

Die vorliegende Arbeit beschäftigt sich mit der Erarbeitung der Möglichkeit eines in-situ Wiederherstellungsprozesses der dielektrischen Eigenschaften von plasmageschädigten, porösen low-k Materialien. Bei Plasmaätzprozessen tritt eine Kohlenstoffffverarmung und Verdichtung der Schichten auf. Damit steigt die Permitti…

The hydrolytic activity of enzymes produced by Trichoderma asperellum, immobilized biodegradable films, as growth inhibitor of microorganisms was tested. The inhibitory activity was demonstrated on Aspergillus niger, Penicillium sp. and Sclerotinia sclerotiorum, microorganisms usually related to the attack and/or food…

First shells of hydration and bulk solvent plays a crucial role in the folding of proteins. Here, the role of water in the dynamics of proteins has been investigated using a theoretical protein-solvent model and a statistical physics approach. We formulate a hydration model where the hydrogen bonds between water molec…

We discuss two types of defects in two-dimensional lattices, namely (1) translational dislocations and (2) defects produced by a rotation of the lattice in a half-space. For Lipschitz-continuous and $\Z^2$-periodic potentials, we first show that translational dislocations produce spectrum inside the gaps of the period…
