I. INTRODUCTION Liquid detergents make a major contribution to the overall detergent and cleaners market, due in part to their handling characteristics and their ease of use. However, in numerous cases, the formulations would lack either consumer appeal or essential physical properties if they did not include additive…
The RCSB validates PDB data while considering the evolving nature of data and nomenclature standards. In order to provide the community with high quality data, the RCSB Protein Data Bank (www.pdb.org) has developed a number of tools that support the deposition and processing of X-ray and NMR structures and that are ba…

We have prepared sodium tellurite glasses doped with europium. Emission intensity of the europium-doped glass is at least 500× more than that of the undoped glass. Fluorescence features exhibited dependence on the pump laser wavelength. Persistent spectral hole burning was observed in the F07→D05 transition of Eu3+. M…
In the vicinity of their resonance frequency, piezoelectric resonators are highly sensitive to small perturbations. The present report is focused on the magnetic field as a perturbation source. Magnetocapacitance modulation of more than 5% is achieved at room temperature on both ferroelectric single crystals and quart…

Polymer blends are capable of providing materials which extend the useful properties beyond the range that can be obtained from single polymer equivalents. Blends of Acrylonitrile-Butadiene- Styrene (ABS) and Polycarbonate (PC) were prepared in different ratios by melt blending technique which was carried out using a…
Abstract The development of reliable and reproducible chemistries for the immobilization of biomolecules to a conducting polymer is a key challenge in the design and preparation of a CP‐based biosensor. In this article, the syntheses and electropolymerization of a series of new 3‐alkylthiophene derivatives functionali…
Abstract Binary melt blends of two thermoplastics—poly(trimethylene terephthalate) (PTT) and polyamide‐12 (PA12)—having a large difference in zero‐shear viscosity values, were prepared in different blending ratios (PTT/PA12 90/10, 75/25, 25/75, 10/90) by means of a twin‐screw extruder. Scanning electron microscopy (SE…
Abstract A further study on mechanical properties and morphology evolution of high density poly (ethylene)/ethylene‐vinyl acetate/and organically‐modified montmorillonite (HDPE/EVA/OMT) nanocomposites exposed to gamma‐rays (0–200 kGy) has been achieved. The results showed that nanocomposites have superior irradiation‐…
Studies of Mg2Cu6Ga5 reveal that this compound contains incomplete Bergman clusters in its structure and shows a pseudogap and empty bonding states just above the Fermi energy according to band calculations. Under a rigid band assumption, such a compound may be tuned to approximant and quasicrystal phases in which the…
Abstract Cationic polyelectrolytes with pyridinium and 1,2‐dimethylimidazolium functionalities based on a hyperbranched polyglycerol scaffold with a narrow polydispersity were prepared by a polymer analogous reaction in a one‐pot synthesis. By the variation of the spacer lengths between the cationic functionalities an…
The mono/bifunctional and metallo/non-metallo properties of Bacillus subtilis DAHPS (3-deoxy-D-arabino-heptulosonate 7-phosphate synthase) have been controversial for several decades. The present study investigated the DAHPSs from both the B. subtilis parent Marburg strain and the derivative strain 168 in detail and c…
Abstract The upconversion luminescence in Nd 3+ ‐doped bismuth–borate glass, excited by 0.8 µm light, was studied in the visible spectral region. Four distinct emission bands were found. From their kinetics, two mechanisms can be shown to be responsible for all four lines: energy‐transfer upconversion, slightly domina…
We report the x-ray photocurrent response of a coplanar chemical vapor deposition diamond detector fabricated using a metal-less graphitic ohmic contact. Ion implantation of 70 keV boron ions to a dose of 2×1016cm−2 was performed through a patterned photoresist to produce a coplanar graphitic contact structure. The de…
We have measured the solubilities of manganese dioxide and aluminum oxide in isobutyric acid + water along its critical isopleth at temperatures above the upper critical solution temperature at 26.2 degrees C. Both oxides are basic anhydrides that react with isobutyric acid to produce the metal isobutyrate and water.…
Abstract Es wird ein Überblick über den Stand der Technik, der experimentellen Analyse und der modellmäßigen Erfassung der im Pkw‐Bereich wichtigsten Abgasreinigungsverfahren – 3‐Wege‐Katalysatoren für λ‐geregelte Otto‐Motoren, NO X ‐Speicherkatalysatoren und Dieselrußfilter – gegeben. Während der serienmäßig eingeset…
Purpose To investigate the inhibitive effect of Congo red dye (CR) for aluminium corrosion in strong alkaline solutions and evaluate the synergistic effect of halide ions on the inhibition efficiency. Design/methodology/approach Corrosion rates of aluminium test coupons were determined by gravimetric technique at 30 a…
Ni(x)Pb(1-x) nanowire arrays were successfully fabricated by AC electrodeposition within the nanopores of ordered porous alumina films prepared by a two-step anodization. Transmission electron microscopy analyses showed that the Ni-Pb nanoarrays are polycrystalline with dimension uniformity around 20 nm in diameter an…
Abstract The synthesis and characterization of a new series of aromatic polyesters based on D‐mannitol and galactitol are described. These polyesters were obtained by polycondensation reaction of the terephthaloyl chloride or isophthaloyl chloride and 2,3,4,5‐tetra‐ O ‐methyl‐D‐mannitol or 2,3,4,5‐tetra‐ O ‐methyl‐gal…
