A general comparison of fundamental distinctions between the FeO(2+) and FeS(2+) complexes in an identical cyanide or isocyanide ligand environment for methane hydroxylation has been probed computationally in this work in a series of hypothetical [Fe(IV)(X)(CN)5](3-), [Fe(IV)(X)(NC)5](3-), (X = O, S) complexes. We hav…
Dielectrophoresis has been used as a technique for the parallel localization and alignment of both semiconducting and metallic carbon nanotubes (CNTs) at junctions between electrodes. A variation of this technique known as floating potential dielectrophoresis (FPD) allows for a self-limiting number of CNTs to be local…
Thiol peroxidase (Tpx) is an atypical 2-Cys peroxiredoxin, which has been suggested to be important for cell survival and virulence in Gram-negative pathogens. The structure of a catalytically inactive version of this protein in an orthorhombic crystal form has been determined by molecular replacement. Structural alig…
The bifunctional enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2) is a key regulator of carbohydrate metabolism in liver. The goal of this study was to elucidate the regulatory role of Ser-32 phosphorylation on the kinase domain mediated dimerization of PFK-2/FBPase-2. Fluorescence-based ma…
„I like refereeing because it allows me to deploy my fault-finding talent. The biggest problem that scientists face is being misjudged geniuses. …︁“ This and more about Martin Jansen can be found on page 8420.
Superiority of the hydriding combustion (HC) technique over conventional metallurgical approach to the synthesis of cost-effective Mg based hydrides, which show promise as hydrogen storage materials, is well known. In the present research, we report further improvements in HC prepared Mg -based materials, achieved by…
{101̄1} semipolar GaN-based light-emitting diodes (LEDs) grown on 1° miscutm-plane sapphires substrates via metal organic chemical vapor deposition showed undulated surface morphology with ridges and valleys. On the ridge regions, two dominant emission peaks, one at a shorter wavelength (∼438 nm) and one at a longer w…
Dynamics of $S=1$ antiferromagnetic bond-alternating chains in the dimer phase, in the vicinity of the critical point with the Haldane phase, is studied by a field theoretical method. This model is considered to represent the compound Ni(C${}_{9}$H${}_{24}$N${}_{4}$)(NO${}_{2}$)ClO${}_{4}$ (abbreviated as NTENP). We d…
The cloud chambers described here are large, made from readily available parts, simple to set up and always work. With no source in the chamber, background radiation can be observed. A large chamber means that a long rod containing a weakly radioactive material can be introduced, increasing the chance of seeing decays…
Abstract To realize the full potential of carbon nanotubes (CNTs) in polymer/CNT nanocomposites, many complicated chemical treatments have been developed to modify the CNTs. Nevertheless, the reinforcing efficiency is still not satisfactory in most cases. In this study, a dramatically improved mechanical enhancement i…
The host compound 9-(3-trifluoromethyl)-9H-xanthen-9-ol forms inclusion compounds with dimethylformamide, dimethylsulphoxide and 1,4-dioxane. The structures of the inclusion compounds as well as that of apohost have been elucidated. The kinetics of enclathration and of desorption have been analysed.
The NADPH-dependent carbonyl reductase S1 from Candida magnoliae stereoselectively catalyzes the reduction of ethyl 4-chloro-3-oxobutanoate (COBE) to ethyl (S)-4-chloro-3-hydroxybutanoate (CHBE), which is a chiral compound valuable as a building block for pharmaceuticals. Carbonyl reductase S1 was expressed in Escheri…
We address the problem of geometry, dynamics, and electronic structure of single-stranded DNA oligonucleotides (ssDNA) inside semiconducting carbon nanotubes (CNTs) from a theoretical and numerical perspective. Atomistic molecular dynamics simulations coupled with electronic structure theory calculations based on an e…
In this study, the authors have proposed and developed a new forming process—rolling with shear (RS-technology) characterized by volume stressed state with severe plastic deformation. A hereditary effect of the rod structure on the physical–mechanical properties and structure of wire made by RS-technology has been inv…
Polymer-coated surfaces may provide a low-cost route for processing and fabricating organic-based electronic devices.
Background: Human mesenchymal stem cells (hMSCs) show potential for therapeutic cellular cardiomyoplasty. However, a range of delivery methods, including direct intramyocardial injection, have resulted in poor engraftment in vivo. We used the in vivo rat heart model to study hMSC engraftment and retention in a normal…
A-site-ordered perovskites LaCu(3)(Ge(3/4)Ga(1/4))(4)O(12) and DyCu(3)(Ge(3/4)Ga(1/4))(4)O(12) were synthesized, and their magnetism was investigated. Ferromagnetic ordering of the square-planar-coordinated Cu(2+) spins was observed at 12-13 K in both compounds, and the Dy(3+) moment in DyCu(3)(Ge(3/4)Ga(1/4))(4)O(12)…
We propose a way to determine the pairing state of the iron pnictide superconductors exploiting the momentum ($\mathbit{Q}$) scan of the neutron scattering data. We investigate the spin susceptibility in the ${s}_{\ifmmode\pm\else\textpm\fi{}}$ and ${s}_{++}$ superconducting states for various doping levels using the…
We introduce a complete implementation of viscoelastic model for numerical simulations of the phase separation kinetics in dynamic asymmetry systems such as polymer blends and polymer solutions on a graphics processing unit (GPU) by CUDA language and discuss algorithms and optimizations in details. From studies of a p…
Abstract Fuel‐cell‐based auxiliary power units benefit from the high power density and fuel flexibility of solid oxide fuel cells (SOFCs), facilitating straightforward onboard fuel processing of diesel or jet fuel. The preferred method of producing the fuel gas is autothermal reforming, which to date has shown the bes…
