FeNi binary nanowires with gradient composition are fabricated by the electrodeposition method. The energy dispersive spec-trometer line-sweep results show that the composition changes gradually along the wire axis. The gradient FeNi nanowires exhibit polycrystalline and crystal twinning at different areas along the n…
It is shown that the performance of inverted organic solar cells can be significantly improved by facilitating the formation of a quasi‐ohmic contact via solution‐processed alkali hydroxide (AOH) interlayers on top of n‐type metal oxide (aluminum zinc oxide, AZO, and zinc oxide, ZnO) layers. AOHs significantly reduce…
Since the iron-age and throughout the industrial age, humans have been exposed to iron oxides. Here, we review the evidence from epidemiology, toxicology, and lung bioavailability as to whether iron oxides are likely to act as human lung carcinogens. Current evidence suggests that observed lung tumors in rats result f…
The P3HT:PCBM (P3HT = poly(3-hexylthiophene, PCBM = phenyl-C61-butyric acid methyl ester) bulk-heterojunction (BHJ) organic photovoltaic (OPV) cells using the AB diblock and ABA triblock copolymers (A = polystyrene derivative with donor-acceptor units (PTCNE) and B = P3HT) as compatibilizers were fabricated. Under the…
A slow pyrolysis of pinewood was investigated in this paper. Through the briquette process, the pinewood sawdust becomes molded biomass. The molded bio-char was produced from molded biomass with different pyrolysis factors, and the bio-char's heating value, char yield rates, and physicochemical and morphological prope…
Chloride ion penetration is the main cause of steel corrosion in reinforced concrete, and significantly aggravates the degradation of concrete durability. With the development of concrete structures that are hydraulic or situated in the ocean, concrete is more often subjected to environments with high hydrostatic pres…
Abstract A nanocomposite of polyaniline (PANI)/mesoporous tungsten trioxide (m‐WO3) was synthesized by the chemical oxidation polymerization of aniline coated onto an ordered m‐WO3 and investigated as an anode material for lithium‐ion batteries. The nanocomposite was characterized by using X‐ray diffraction, Fourier t…
Abstract A simple yet versatile binder‐free electrophoretic deposition method is developed to fabricate a carbon‐coated Si/reduced graphene oxide (Si@C/rGO) nanocomposite as a high‐performance anode for lithium‐ion batteries. In this nanostructure, high specific capacity Si nanoparticles are uniformly coated with the…
We report about the use of trapped-field HTS bulk Maglev above a PM guideway. Guideway and superconductors need a robust design and safe operation at LN2cryogenic temperatures. Cryogenic refrigeration in compact cryostat design has been successfully proved. First generation of 40-cm-long bulk vacuum cryostats are capa…
Abstract In this article, the catalytic activity of titania‐supported gold nanoparticles (Au/TiO2) was studied for the selective oxidation of amines into nitroso compounds using hydrogen peroxide (H2O2). Gold nanoparticles deposited on Degussa P25 polymorphs of titania (TiO2) have been found to promote the selective f…
This study presents a coupled electric–magnetic–thermal–mechanical analysis of busbar systems under short‐circuit currents. The analysis is carried out by making use of the finite‐element method, which enables one to closely model two‐way interactions among separate continuum physics. In contrast to previous works, wh…
OBJECTIVES: This article uses conventional and newly extended solubility parameter (δ) methods to identify polymeric materials capable of forming amorphous dispersions with itraconazole (itz). METHODS: Combinations of itz and Soluplus, Eudragit E PO (EPO), Kollidon 17PF (17PF) or Kollidon VA64 (VA64) were prepared as…
We used static DFT calculations to analyze, in detail, the intramolecular hydrogen bonds formed in low-molecular-weight polyethylene glycol (PEG) with two to five repeat subunits. Both red-shifted O-H⋅⋅⋅O and blue-shifting C-H⋅⋅⋅O hydrogen bonds, which control the structural flexibility of PEG, were detected. To estim…
The reaction mechanism, the equilibrium composition, the temperature range of stability of formed intermediates as well as the kinetics and thermodynamics of activated state during the formation of monoclinic strontium-aluminum-silicate feldspar stroncian (SrAl2Si2O8) via the ceramic route from the mixture of SrCO3, A…
Hepatic metastasis is the leading cause of mortality of colon cancer, which is still lack of an effective therapy. A new delivery system, pluronic P85 block copolymers, conveying chemotherapeutic agent 5-fluorouracil (5-Fu) for inhibiting growth and metastasis of colon cancer was designed and developed. In this study,…
The protein universe consists of a continuum of structures ranging from full order to complete disorder. As the structured part of the proteome has been intensively studied, stably folded proteins are increasingly well documented and understood. However, proteins that are fully, or in large part, disordered are much l…
Deciphering the extracellular signals that regulate SMC differentiation from stem cells is vital to further our understanding of the pathogenesis of vascular disease and for development of cell-based therapies and tissue engineering. Hyaluronan (HA) has emerged as an important component of the stem cell niche, however…
Pulse electron paramagnetic resonance (EPR) is gaining increasing importance in structural biology. The PELDOR (pulsed electron-electron double resonance) method allows extracting distance information on the nanometer scale. Here, we demonstrate the efficient extraction of distances from multimeric systems such as mem…
Cryo-electron tomography (cryo-ET) provides great insights into the ultrastructure of cells and tissues in their native state and provides a promising way to study the in situ 3D structures of macromolecular complexes. However, this technique has been limited on the very thin specimen, which is not applicable for most…
GeTe has been predicted to be the father compound of a new class of multifunctional materials, ferroelectric Rashba semiconductors, displaying a coupling between spin-dependent k-splitting and ferroelectricity. In this paper, we report on epitaxial Fe/GeTe(111) heterostructures grown by molecular beam epitaxy. Spin-pu…
