Compartmentalization is a major prerequisite for the origin of life on earth according to Wächtershäuser "Iron-Sulfur-World". The hypothesis is mainly based on an autocatalytic inorganic energy reproducing redox system consisting of iron and sulfur as requirement for the subsequent synthesis of complex organic structu…
Metal catalyst free carbon nanotube (MCFCNT) whiskers were first used as an electrode modification material on a gold electrode surface for zinc voltammetric measurements. A composite film of Nafion and MCFCNT whiskers was applied to a gold electrode surface to form a mechanically stable sensor. The sensor was then us…
This article mainly focusses on the improvement of metal forming die tooling for equal channel angular extrusion (ECAE) processes through nonrectangular 2θ-dies of classical Segal geometry. The technological appropriateness of workpiece deformation through 2θ-dies using inclined oblique 2θ-punches has been evaluated w…
A series of high strength weld metals with varying Al content are studied. The inclusions are characterised using energy dispersive X-ray analysis and electron diffraction. The tendency for alignment of the microstructure is characterised quantitatively using electron backscatter diffraction and a recently developed p…
Osteopontin (OPN) is an acidic, glycosylated and phosphorylated protein that plays an essential role in determining the aggressiveness and oncogenic potential of several types of cancer, including lung cancer. The OPN function is highly dependent on post-translational modification (PTM) and regulation of the processes…
Critical wetting transition for short-range forces in three dimensions ($d=3$) is reinvestigated by means of Monte Carlo simulation. Using an anisotropic finite size scaling approach, as well as approaches that do not rely on finite size scaling, we show that the critical wetting transition shows clear deviation from…
Abstract magnified image In this work we demonstrate that, based on a simple and versatile fabrication method, the collective use and integration of high aspect ratio (AR) nanostructures, here Si and ZnO nanowires (NWs), is possible and addresses multiple application fields, including light detection, active materials…
Recently, graphitic carbon nitride (g-C3N4) materials have received a great attention from many researchers due to their various roles as a visible light harvesting photocatalyst, metal-free catalyst, reactive template, nitrogen source of nitridation reaction, etc. g-C3N4 could be prepared by temperature-induced polym…
FtsZ polymerizes to form a cytokinetic ring at the center of a bacterial cell, which engineers bacterial cell division. FtsZ consists of N-terminal and C-terminal core domains followed by a C-terminal spacer and a conserved C-terminal tail region. Though it has been reported that both N- and C-domains can fold indepen…
The effects of structural isomerism and stereoisomerism in molecular adsorption at surfaces are studied through the reaction of four cyclohexanediamine isomers— cis -1,2-, trans -1,2-, cis -1,4-, and trans -1,4-cyclohexanediamine—at the Ge(100)-2 × 1 semiconductor surface. Using a combination of X-ray photoelectron sp…
Flexible thin film super-capacitors with the silver paste current collector were printed and their electrochemical characteristics were investigated to apply for a low cost solution-based printing process. The silver paste current collector was printed on a flexible Polyethylene Telephtalate (PET) substrate and the ac…
The Src family of tyrosine kinases (SFKs) regulate numerous aspects of cell growth and differentiation and are under the principal control of the C-terminal Src Kinase (Csk). Csk and SFKs share a modular design with the kinase domain downstream of the N-terminal SH2 and SH3 domains that regulate catalytic function and…
A series of 1,3‐bis(2′‐hydroxyethyl)imidazolium ionic liquids is reported where 1H NMR chemical shift values and thermal stabilities (Td), as determined by thermogravimetric analysis, are correlated with the hydrogen bonding capability of various anions ([Cl−], [Br−], [CF3CO2−], [NO2−], [MsO−], [NO3−], [TfO−], [BF4−],…
The photoelectrochemical effects of a series of phenylalkanoic acids as co-adsorbents along with a ruthenium sensitizer, cis-diisothiocyanato-bis(2,2'-bipyridyl-4,4'-dicarboxylato) ruthenium(II) bis-tetrabutylammonium dye (N719), were investigated in dye-sensitized solar cells (DSSCs). All the co-adsorbents used in th…
As one of the promising adsorbents, activated carbon fibers were modified in order to enhance their sulfur dioxide removal efficiency by depositing strong oxidants. Potassium permanganate (KMnO 4 ) was found to be an effective promoter for activated carbon fibers. The optimum content of KMnO 4 on activated carbon fibe…
The influence of the transparent conducting oxide (TCO) topography was studied on the performance of a silicon oxide intermediate reflector layer (IRL) in a-Si/μc-Si tandem cells, both experimentally and by 3-D optical simulations. Therefore, cells with varying IRL thickness were deposited on three different types of…
ATPases associated with various cellular activities (AAA+) form a superfamily of ring-shaped motor proteins that utilize cyclical allosteric motions to remodel or translocate substrate proteins (SP) through a narrow central pore. The p97 ATPase is a homohexameric, double-ring member of this superfamily that encloses a…
GaN-based light-emitting diodes (LEDs) on patterned sapphire substrate (PSS) with patterned composite SiO(2)/Al(2)O(3) passivation layers and TiO(2)/Al(2)O(3) distributed Bragg reflector (DBR) backside reflector have been proposed and fabricated. Highly passivated Al(2)O(3) layer deposited on indium tin oxide (ITO) la…
Preparing new ternary compounds via traditional high temperature synthesis techniques is essentially limited to ternary compounds that are thermodynamically more stable than any mixture of binary compounds because binary compounds typically form as reaction intermediates. By using a precursor having elemental layers t…
We investigate the nuclear isotropic shielding constants σ((13)C) and σ((17)O) of isomers of retinoic acid and retinal in gas-phase and in chloroform, acetonitrile, methanol, and water solutions via Monte Carlo simulation and quantum mechanics calculations using the GIAO-B3LYP∕6-311++G(2d,2p) approach. Electronic solu…
