Abstract High‐density polyethylene was functionalized using a thermolysis method in the presence of functionalized peroxides at different temperatures and at various peroxide concentrations. It was found that both percentage cross‐linking (% CL) and percentage functionalization (% Fn) increased with an increase in per…
Cu(3)Bi(2)S(3)I(3) was crystallized during an attempt to synthesize Cu-Pb-Bi sulfosalts with iodine as the transport medium. The crystal structure was solved from a black needle-like crystal on a four-circle diffractometer with a CCD detector. The solution was obtained by direct methods and subsequent difference-Fouri…
Abstract High‐density polyethylene was thermolysed with short‐chain organic compounds (additives) with an ester functional group in the presence of free radical initiator such as dicumyl peroxide at 160°C. The experimental results inferred that an additive with a hydrogen donor containing a thiol group showed better e…
Abstract Endoscopic palliation for the obstructive jaundice caused by biliary or pancreatic malignant tumors is a commonly used medical treatment. However, plastic biliary stents are occluded by sludge deposition caused by bacterial adhesion in 3–5 months. Chitosan, which has both good biocompatibility and antimicrobi…
The goal of this work was to investigate the dynamics of human plasma fibronectin (HFN) at the oil-water interface and to characterize its interactions with human serum albumin (HSA) by total internal reflection fluorescence microscopy (TIRFM). Among key results, we observed that fibronectin adsorption at the oil-wate…
Abstract The growth of silicon macropores under high current densities and high HF concentrations is studied. A new growth mode for porous Si has been found where pores resemble the so‐called current line oriented pores previously discovered in InP. For the achievement of that the electrolyte had to be optimized in re…
Abstract Reactive mineral powders were prepared with a vinyl monomer as an intercalating agent, which was grafted onto the surface of nanoclay layers, to offer crosslinking points between the nanoclay layers. According to IR characterization, the vinyl group of (3‐acrylamidopropyl)trimethylammonium chloride, grafted o…
Laterally structured hybrid assemblies composed of genetically engineered polypeptides and fused-ring organic molecules were used to guide the assembly of gold nanoparticles in a site-selective fashion (see image). Gold-binding protein was covalently bonded onto a self-assembled monolayer of preformed, π-conjugated th…
The superstructure recently discovered in [Fe(pic) 3 ]Cl 2 .EtOH at temperatures inside the step region of the high-spin–low-spin transition curve sheds new light on the anomalous transition behaviour in spin crossover compounds. The structure of the metastable LIESST state of [Fe(pic) 3 ]Cl 2 .EtOH at 10 K has been m…
Abstract A series of glycol dibenzoates was synthesized by transesterification of glycols with methyl benzoate. PVC films were prepared from suspension grade PVC and the dibenzoates at a constant content of the dibenzoates. The mechanical properties of the films were measured. In addition, the extractability and the a…
To study the microtrack signal, noise and track “skirts” a time-domain technique [A. Taratorin, M. Xiao, and K. Klaassen, IEEE Trans. Mag. 40, 129 (2004)] was used. It shows that the standard microtrack preparation (two-sided dc erasure) suffers from demagnetization caused by the write head fringe fields. Low density…
Abstract The effect of electron beam irradiation on ethylene‐propylene terpolymer (EPDM) was investigated. A 50‐part oil‐extended EPDM with high termonomer (ENB) content (iodine number of base polymer) 19, was selected for this study. An increase in irradiation dose from 0 to 200 kGy resulted in increased crosslinking…
Spektakuläre Größen (fast 1000 Atome) und Molmassen (ca. 33 000 g mol−1) sowie sphärische Symmetrie kennzeichnen die beiden titelgebenden Polyoxowolframate mit X=P, As (siehe Bild; Sn blau, C grün). Die Strukturen bestehen aus 12 Keggin-Fragmenten A-XW9O34 (gelb, rot), die durch 36 Dimethylzinn-Gruppen verbunden sind…
Cr-doped AlN thin films were epitaxially grown on Al2O3(001) substrates at low temperature by reactive magnetron sputtering,and their magnetic properties were investigated. Extensive x-ray diffraction studies indicated that the films have a wurtzite-type hexagonal structure and are (001) oriented, with an epitaxial re…
In this paper we calculate the magnetocaloric effect in the compound MnFeP 0.45 As 0.55 . We use a microscopical model in the picture of the band theory, including a magnetoelastic interaction. The theoretically calculated isothermal entropy changes upon magnetic field variations are in good agreement with the availab…
Conformational structure changes in concanavalin A (Con A), a legume lectin protein which is composed of 18 beta-strands, induced by dissolving in 50% trifluoroethanol (TFE) were monitored at neutral and low pH by far- and near-UV circular dichroism (CD), fluorescence, and FTIR under equilibrium conditions. Stopped-fl…
The structure, stability, and conformational dynamics of an assembly of two pentameric bundles made of collagen-like triple helical segments are explored using 1.2 ns molecular dynamics simulations in three environments: 8.0% (v/v) formaldehyde/water solution, 1.4% (v/v) gallic acid/water solution, and pure water. Sta…
The ordered perovskite Sr(2)YTaO(6), distrontium yttrium tantalum hexaoxide, has been reported as showing an unusual triclinic structure, at odds with the results from a recent group-theoretical analysis. A new investigation establishes that Sr(2)YTaO(6) and the isostructural Sr(2)YNbO(6), distrontium yttrium niobium…
Abstract Peanuts have been cultivated worldwide for hundreds, if not thousands, of years. However, most peanuts are sold without the shell, and so large quantities of peanut shells remain as byproducts in the field, not being used properly. In this work, the feasibility of making particleboard from milled peanut shell…
Abstract An infrared spectroscopy method was devised to uncover evidence of hydrogen bonding and intermolecular interaction between components in solid poly(lactic acid) (PLA) and poly(hydroxyester ether) (PHEE) blends. The method compares Gaussian/Lorentzian deconvoluted infrared spectra of the polymer blends with de…
