All-aromatic hyperbranched polyesters with hydroxy endgroups were functionalized with aliphatic n-alkyl carboxylic acids. The length of the n-alkyl chain as well as the degree of modification were varied and the resulting, partially amphiphilic polymers were characterized by differential scanning calorimetry (DSC). Wi…

Amorphous powders were synthesized by spray‐drying aqueous solutions of calcium and aluminum nitrates, followed by calcination in order to completely decompose the salts. The formation of pure calcium aluminates—C 3 A, C 5 A 3 , C 12 A 7 , CA, CA 2 , and CA 6 (C = CaO and A = Al 2 O 3 )—has been studied by DSC and XRD…

Reaction of indole with Br2 led to isolation of an indole trimer 2, formed by linking the 2- and 3-positions of each indole to form a central aromatic ring, and brominated at the 5- and 6-positions of each indole. The X-ray structure of [2]·acetone·2DMF showed π-stacking of the planar aromatic molecules with two diffe…

The performance of a single‐chamber solid‐oxide fuel cell (SOFC) made from an yttria‐stabilized zirconia solid electrolyte with a (GDC)‐containing Ni anode and a cathode was found to be significantly enhanced by the deposition of Mn, Ga, Cr, Ce, and Lu oxide layers on the YSZ surface. In particular, the deposition of…

A relatively detailed search for the optimum composition of phosphor was achieved by the pseudocombinatorial chemistry method (PCCM). The optimum ratio of BaO to was first found in terms of emission. As a result, the maximum luminance was obtained at the ratio of 1.3/6. Based on the host composition determined as , th…

Islamic star patterns are a beautiful and highly geometric art form. Many analyses have been done of their complex structure and symmetries. We pick up one line of analysis based on placing stars and rosettes in a formation dictated by a tiling of the plane, and develop a software implementation of the technique. We d…

In contrast to what is often expressed in the literature, reversible and irreversible solid(s)-solid(s) transitions in binary system of non-racemizable enantiomers are not always referred to as polymorphism. Order-disorder phenomena, miscibility gaps with critical temperatures and transitions in which three-phases or…

The partial discharge (PD) measurement is a sensitive method for testing and monitoring the insulation condition of HV apparatus. Digital PD measurements have become state of the art. Computer-based PD diagnostic systems nowadays can be used to increase the reliability of modern gas-insulated system (GIS). Also on-lin…

Methanol can be selectively decomposed to carbon monoxide and hydrogen at a reaction temperature as low as 433 K over ceria-supported palladium catalysts prepared by deposition–precipitation and by impregnation methods, with the former method resulting in the higher catalytic activity. Cationic palladium species can b…

Three low-molecular weight polyesters, poly(L-lactic acid) (PLA), copoly(lactic acid/glycolic acid) (PLGA) and poly(delta-valerolactone) (PV), were used to prepare water-soluble sodium diclofenac-loaded microspheres by using the oil-in-oil (o/o) emulsification-solvent evaporation method. Their micromeritic and physico…

2-Methacryloyloxyethyl phosphorylcholine (MPC) polymers, which have excellent biocompatibility, have been receiving increasing attention in biomedical and bioengineering fields; however, the mechanical strength of the hydrated MPC polymers is not sufficient for use in these fields as a bulk material. Therefore, we hyp…

An interpenetrating polymer network (IPN) of poly(acrylamide-co-ethylene glycol) (p(AAm-co-EG)) hydrogel was covalently grafted to polyethylene terephthalate (PET) angioplasty balloons to increase surface hydrophilicity and improve lubricity. A 2-step graft polymerization protocol was followed to first polymerize and…
