Abstractauthoren Lithium/potassium borohydride LiK(BH) was recently synthesized and reported to be in a Pnma phase at ambient conditions. Subsequent theoretical studies show that this phase is metastable at finite temperatures up to 400 K. Studying the Pnma phase of LiK(BH) by first-principles calculations, we show th…
Aim: During the process of wound healing it is really important to keep the area safe from bacteria infections and treat possible inflammation incidents. Model antiseptic and anti-inflammatory agents can be encapsulated into a drug delivery carrier for combined treatment. Electrospinning (E-Spin) has been acknowledged…
Negative-tone block copolymer (BCP) lithography based on in situ surface chemical modification is introduced as a highly efficient, versatile self-assembled nanopatterning. BCP blends films consisting of end-functionalized low molecular weight poly(styrene-ran-methyl methacrylate) and polystyrene-block-Poly(methyl met…
Abstractauthoren The method of estimation of the square modules for the -pole components of the crystal-field Hamiltonian , prior to its conventional parametrization, is presented. The method is founded on the additivity of the squares of the multipolar second moments of the CF splittings to the square of the global s…
Ein Graph für Graphene: Die Erwartungen bezüglich der Anwendungsmöglichkeiten von Graphen sind enorm. Ein klares System zur Bezeichnung von Graphenderivaten fördert eine präzise Fachsprache für die Familie der graphenbasierten Materialien. Im Rahmen des GRAPHEN-Flagship-Projekts der EU wurden drei physikalisch-chemisc…
The magnetization reversal mechanisms of small rings have been investigated as a function of the geometry. Stepped and non stepped hysteresis loops were obtained and four different reversal mechanisms were identified. In spite the important information that is possible to get from the hysteresis loops, in some cases i…
ABSTRACT Fluorine‐containing vinyl ether monomer is a combination of UV‐curing technology and low surface energy materials. In this article, a type of fluorine‐containing vinyl ether monomer was synthesized by the reaction of fluorinated alcohols, hexafluorobenzene, 2‐vinyloxy ethanol, and sodium hydride. These monome…
ABSTRACT Network formation was monitored by shear storage modulus (G′) during free radical crosslinking polymerization to investigate the effects of pH and ethylenediaminetetraacetic acid (EDTA; a complex agent). Three types of acrylic monomers, acrylic acid (AAc), 2‐acrylamidoglycolic acid (AmGc), and 2‐acrylamido‐2‐…
SUMMARY Whenever a power transformer in a no‐load condition is manually tripped, a residual flux appears in the transformer core, which causes an inrush current when the transformer is later re‐energized. However, the true nature of residual fluxes has not yet been experimentally elucidated. The authors interpreted th…
This is the second case in literature of posterior reversible encephalopathy syndrome (PRES) in a twin pregnancy complicated by preeclampsia-eclampsia. A 27-year-old primigravida with dichorionic diamniotic twin pregnancy was admitted at 36 weeks of gestation for induction of labour due to preeclampsia. On the second…
The stereospecific oxidative decomposition of urate into allantoin is the core of purine catabolism in many organisms. The spontaneous decomposition of upstream intermediates and the nonenzymatic racemization of allantoin lead to an accumulation of ( R )-allantoin, because the enzymes converting allantoin into allanto…
Electrical resistivity and alternating current susceptibility measurements were performed for the spin–ladder compound SrCa13Cu24O41 under hydrostatic pressure up to 8 GPa. The superconducting transition was observed below TC = 14.7 K at pressures above 2 GPa. By using high-quality single crystals, the bulk supercondu…
Commercial grade AM50 magnesium alloy was diecast to varying wall thickness using both the RheoMetal process and conventional liquid casting. The resulting microstructure and pore structure were analysed. The rheocast material had larger pores than the conventionally cast material, scattered over the central 50% of th…
A Salmonella typhimurium (S. typhimurium) biosensor based on a fluorescence resonance energy transfer between upconversion and gold nanoparticles is reported. NaYF4:Yb,Er nanoparticles were synthesized and modified with a S. typhimurium target DNA complementary sequence to form the sensor. Gold nanoparticles were modi…

Materials which can augment and repair the function of damaged bone are required. Metals, ceramics and plastics have been widely used as artificial bone implants, although their material properties are not optimally matched to those of the native bone tissue. New materials, and methods of production, are being extensi…
Biomaterials for Scaffolds: Natural Polymers - 1
We have prepared polycrystalline Co2FeSi thin films on a number of seed layers to optimize their structural and magnetic properties. Using a Cr/Ag combined seed layer, films have been produced with extremely low interfacial roughness (<1 nm) and controllable coercivities in the range 12–27 Oe. Such a structure would b…
ABSTRACT Rare earth elements can improve the performance of polymers because of their special 4f orbitals. The nucleation and stabilization of radical groups of rare earth particles can affect the structure of polypropylene (PP) and its properties. In this study, samarium oxide (Sm2O3) particles were used as a cocatal…
Abstract The metal‐organic framework {[Zn2(CAM)(μ2‐OH)(bpp)]·2H2O}n (1) [H3CAM = 4‐hydroxypyridine‐2,6‐dicarboxylic acid, bpp = 1,3‐bis(4‐pyridyl)propane], was hydrothermally synthesized and characterized by elemental analyses, infrared spectroscopy, and single‐crystal X‐ray diffraction. Compound 1 presents a three di…
