The European Union has implemented breeding programmes to increase scrapie resistance in sheep. A similar approach can be applied also in goats since the K222 allele provides a level of resistance equivalent to that of ARR in sheep. The European Food Safety Authority stated that breeding for resistance could be offere…
Keratin is a natural polymer found in hair fibers, skin, and nails. It has been investigated as a biomaterial since the 1970s, and has more recently been shown to have applications in healthcare such as medical devices and tissue engineering. Keratins are one of few intermediate filament forming proteins and demonstra…
Abstract Nature's energy needs are met by systems of renewable resources. Light is used to activate reduction of CO 2 while water is oxidized producing energy storage molecules like carbohydrates. Emulating such systems is a challenge. Here we report a visible light driven hybrid soft‐oxometalate based catalyst system…
Cobalt–carbon bond cleavage is crucial to most natural and synthetic applications of the cobalamin class of compounds, and here we present the first direct electronic and geometric structural characteristics of intermediates formed following photoexcitation of methylcobalamin (MeCbl) using time-resolved X-ray absorpti…
LOW DENSITY Fe-Mn-Al-Si STEELS Th e work presents the results of investigations into the structure and phase composition of newly developed high manganese steels of the X98MnAlSiNbTi24-11 and X105MnAlSi24-11 type. The average density of such steels is 6.67 g/cm 3 , which is 15% lower as compared to typical structural…
Nodal diffusion is currently the preferred neutronics model for industrial reactor core calculations, which use few-group cross-section libraries generated via standard assembly homogenization. The infinite-medium flux-weighted cross sections fail to capture the spectral effects triggered in the core environment by no…
We report on the photovoltaic parameters, photophysical properties, optoelectronic properties, self-assembly, and morphology variations in a series of high-performance donor–acceptor (D–A) π-conjugated polymers based on indacenodithiophene and quinoxaline moieties as a function of the number-average molecular weight (…
Abstract Metal/metaloxide based composite materials have wide spread applications in electrochemical sensors and fuel cell applications. Hence, the present work is directed towards the fabrication of cost effective and highly sensitive electrode material for cysteine sensing. In this work, Co‐Gd 2 O 3 nanocomposite is…
The adsorption of cis and trans 2-butenes on Pt(111) has been studied as a function of hydrogen coverage θ H by means of calculations based on density functional theory (DFT) with the inclusion of dispersion forces. All hydrogen coverages have been considered, from 0 to 1.00 monolayer (ML). For each case, the di-σ and…
The aim of this study is to investigate influence of selected parameters of gas tungsten arc welding on microstructure of MAR-M247 nickel based superalloy originating from turbine vane. MAR-M247 is a precipitation-strengthened superalloy which is widely used in aerospace engines. The main strengthening phase in this m…
The aerial parts of extensively used ethnomedicinal plant Mikania cordata (Burm. f.) Robinson growing wild in Bangladesh were investigated to isolate and characterize compounds responsible for the bioactivities of the plant. In the present study, a new derivatives of betulinic acid, 16-hydroxy betulinic acid [3β,16-di…
The behavior of grounding systems against waves with high-frequency content such as lightning or very fast transient overvoltages is completely different from the steady state. This paper presents a more flexible model of a grounding system with respect to frequency dependency of electrical parameters of soil and mois…
On-surface metalation of metal-free phthalocyanine derivatives is a simple and solvent-free way to fabricate MPc compounds. Using phthalocyanine (H 2 Pc) molecules on Ag(111) as an example, we investigated the atomic-scale mechanisms of on-surface metalation processes using first-principles calculations based on densi…
Bone loss is one of the serious health issues in bedridden patients or young generation due to lack of physical activities.Mechanical forces are exerted on the bones through ground reaction forces, liquid loadings and by other contraction activities of the muscles.We are assuming an isotropic half-space with mechanica…
Purpose Transport is an integral part of the nuclear fuel cycle. The procedures employed are designed and conducted to ensure the public and environment protection both routinely and when transport accidents occur. According to this, the purpose of this paper is to focus on a coupled thermal-drop impact analysis-based…
Novel cobalt, nickel and copper complexes were synthesized by regular reflux method and nano sized Co(II), Ni(II) and Cu(II) metal complexes were synthesized by a facile hydrothermal method using green solvent at various temperatures without the addition of any capping agent. The structural characterization was done b…
The effect of the retrogression and re‐aging (RRA) heat treatment on the corrosion behavior of B206 aluminum‐copper casting alloy in artificial seawater employing electrochemical experiments such as electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization, weight loss measurements and microstructu…
Electromagnetic stirrer generates swirling fluid flow, boosts the mixing of molten steel near the solidification front and enhances the quality of the continuously cast products.In the present investigation, attention is paid towards studying the effect of in-mold electromagnetic stirring on fluid flow and solidificat…
In this study, we fabricate a metal- and vacuum-free electrode composed of aligned multiwall carbon nanotubes (MWCNTs) as top electrode in inverted type polymer solar cells. Simply drawn MWCNT sheets from vertically grown arrays were directly transferred over the top layer (PEDOT:PSS) of the device as an anode materia…
In order to develop an efficient resonance self-shielding method that can model the complex resonance-interference effects in depleted fuel compositions, an improved Pseudo Resonant Isotope Model (PRIM) has been developed by incorporating a number density–perturbation technique in the resonance cross-section tables fo…
