It is of interest to explore transfer of fluid through nanopores because of widespread applications for such systems. Carbon Nanotubes (CNTs) with their exceptional properties are the best candidates as building blocks for nanostructures. Water transfer in lots of biological systems acts as an important role for keepi…
Synthesis and properties of photochromic acylated 2‐(N‐arylaminomethylene)benzo[b]thiophene‐3(2H)‐ones are described. Their structure largely depends on the nature of acyl migrant and in a less degree on N‐aryl substituent.
In order to fight oxidative stress we developed antioxidant nanoreactors based on encapsulation of Cu/Zn superoxide dismutase or its mimics in amphiphilic copolymer nanovesicles whose membranes are oxygen permeable. The nanovesicles, made of poly-(2methyloxazoline)poly(dimethylsiloxane)-poly(2-methyloxazoline), succes…
Synthesis of two lignin derivatives, lignophenol and lignin-aminophenol, were presented in this article. The chemical structure and the func-tional groups of lignin derivatives were charac-terized through FT-IR analysis. The immobiliza-tion of three proteases (papain, trypsin and pepsin) on lignin and lignin derivativ…
A semi-probabilistic methodology for predicting the remaining strength of submarine pipelines subjected to internal corrosion based on Recommended Practice RP-F101 by Det Norske Veritas (DNV) is described in this paper. It is used to estimate the maximum allowable operating pressure of the corroding pipelines based on…
The electrochemical oxidation of the chemically prepared polymer poly[2-(3-thienyl)ethyl acetate] (PTEtAc), its partially hydrolyzed derivative PTEtAcOH and the fully hydrolyzed compound poly[2-(3-thienyl)ethanol] (PTEtOH) was studied by in situ electron spin resonance (ESR)/UV-Vis-NIR spectroelectrochemistry. The spe…
Several technologies are being used in distributed generation applications with variable degree of success. Among those are: wind turbines, small-scale hydropower plants, biomass, microturbines, photovoltaic arrays and fuel cells. In a fuel cell, the chemical energy incorporated in the fuel is converted directly to el…
Potential energy surfaces (PESs) for transition metal nanoparticles of Pt, Au, and Ag were derived using the artificial neural network (ANN) method. Three feedforward neural networks were constructed to fit the nonlinear relationship between the binding energy and the nanoparticle information, i.e. size and atomic coo…

The interaction of hydrogen with cerium nickel and aluminium-based mixed oxides (CeNi1OY and CeAl0.5Ni1OY) has been studied by catalytic hydrogenation and Inelastic Neutron Scattering (INS). The mixed oxides are large catalytic hydrogen reservoirs called oxyhydrides and the presence of Al allows increasing hydrogen st…
Although air transport is responsible for only about 2% of all anthropogenic CO2 emissions, the rapidly increasing volume of air traffic leads to a general concern about the environmental impact of aviation. Future aircraft generations have to face enhanced requirements concerning productivity, environmental compatibi…
Journal of Inequalities and Applications is a peer-reviewed open access journal published under the brand SpringerOpen. The aim of this journal is to provide ...
Masses of highly uniform silica-shelled carbon nanotube (CNT) coaxial fibers are synthesized in a single step by the catalytic gas-flow reaction method. This method involves the generation of CNTs in the gas flow from the injection catalytic gas flow reactions and the in situ deposition of silica over the gas disperse…
It plaster moulds gets casted the alloys of following metals: Al, Cu, Ag, Au in precise and artistic founding. The investigation of the crystallization of bronzes in hot plaster moulds the method of the thermal analysis and derivative (TDA) was not realized out so far. Probe TDAg and tripod enabling the execution of m…
The theoretical analysis, design and fabrication of PDMS-prism-coupled Kretschmann surface plasmon resonance (SPR) sensor were presented. The optical properties of very thin metal films have been evaluated by Fresnel analysis, with optical boundary conditions pertaining to the surface plasmon resonance at the gold/wat…
Streszczenie. Artykul przedstawia potencjalne korzyści, m.in. znaczące obnizenie strat energii, wynikające z zastosowania materialow amorficznych w magnetowodach transformatorow rozdzielczych. (Nowoczesne materialy rdzeniowe dla wydajnych transformatorow rozdzielczych).
Parmi les nombreux nanomatériaux existants, les nanotubes de carbone (NTC), dont la production mondiale annuelle atteint plusieurs centaines de tonnes, font partie d’une \ncatégorie de matériaux à part, tant leur potentiel d’application est vaste et leurs propriétés exceptionnelles. La toxicité des NTC est depuis peu…
Introduction In ASDEX Upgrade, the transition from carbon based plasma facing components towards a full tungsten machine offers the opportunity to study the erosion and transport of a high-Z element. In H-mode discharges with type-I ELMs, the tungsten production at the plasma facing components is dominated by the eros…
Se determina el comportamiento mecnico de laminaciones simples y escalonadas modeladas por elementos finitos en condiciones no lineales de esfuerzo-deformacin, para comprender la secuencia de la interaccin de los campos de esfuerzos en los extremos de la grietas. Se estableci una matriz de simulacin variando la extens…
Due to insufficient experimental restraints, a biologically critical loop region in PrP(c) (residues 167-171), which is a potential binding site for Protein X, is under-determined in most mammalian species. Here, we show that by adding information about distance constraints derived from a database of high-resolution p…
