Abstract The chytrid fungus Batrachochytrium dendrobatidis has caused the most prominent loss of vertebrate diversity ever recorded, which peaked in 1980s. Recent incursion by its sister species B. salamandrivorans Europe raised alarm for a new wave declines and extinctions western Palearctic urodeles. European Commission responded restricting amphibian trade. However, private collections, main end consumers, were exempted from legislation. Here, we report how invasion released, exotic newt...
Aluminium-doped (3%) zinc oxide thin films (AZO) were prepared, using pulsed laser deposition, with varying deposition times. The target was fabricated from compacted aluminium-doped nano-powder produced by sol–gel. had a growth consisting of nanostructures in the form columns sharp ends which, for certain times, resemble nano-flowers or nano-leaves. small spheroid-like particles created during columnar act as seed other AZO needles, resulting appearance lotus-like flowers and even smaller...
Abstract In this work, a series of WC/C nanostructured films were deposited on silicon substrates by changing the ratio sputtering power applied to graphite and WC magnetron sources ( P C / : 0, 0.1, 0.5, 1). The thermal stability coatings was followed in situ means X‐ray diffraction measurements up 1 100 °C vacuum (10 −1 Pa). Initially, film microstructure is composed nanocrystalline 1− x W 2 phases. As increases crystallinity decreases, becomes predominant phase from = 0.1. results show...
Nanocrystalline chromium nitride and ternary aluminium thin films were deposited by reactive magnetron sputtering of Cr Al targets in argon/nitrogen atmosphere varying the power gas composition. The coatings characterized terms crystal phase, chemical composition, microstructure, mechanical properties x-ray diffraction, photoelectron spectroscopy, including x-ray-induced Auger electron transmission microscopy, selected-area energy-loss cross-sectional scanning ultramicrohardness tester....
Gold nanoparticles (NPs) have been prepared with three different capping systems: a tetralkylammonium salt, an alkanethiol, and thiol-derivatized neoglycoconjugate. Also gold NPs supported on porous TiO(2) substrate investigated. X-ray absorption spectroscopy (XAS) has used to determine the electronic behavior of capped/supported systems regarding electron/hole density d states. Surface size effects, as well role microstructure, also studied through exhaustive analysis EXAFS (extended fine...
Influence of surface roughness on the friction TiC/a-C nanocomposite coatings while sliding against bearing steel balls in humid air was examined by detailed analyses wear surfaces and scar ball counterparts atomic force microscopy, optical, confocal microscopy. It observed that essentially determines behavior counterpart, which consequently influences transfer film formation. A rough coating causes abrasive during running-in period, impedes formation a stable leads to higher values...
This paper concentrates on an extension of a rather new methodology to determine local residual gradients at enhanced lateral resolution using the so-called slit milling technique. The method is based stress relaxation by making focused ion beam and displacements are measured through digital image correlation so as calculate stress. Our novel approach consists multiple fitting procedure along length instead commonly applied averaging method. applicability our demonstrated when exist. In...
