Hydrothermal treatment of KMnO4 and graphene flakes (GFs) leads to MnO2 nanosheets decorated on GFs. The resulting MnO2/GF (MG) composite has been tested as a supercapacitor electrode in aqueous electrolyte and found to exhibit good cycling stability with a specific capacitance of 147 Fg−1 at a current density of 5 Ag…
The use of hot-melt extrusion for preparing homogeneous API-excipient mixtures is studied for miconazole-PEG-g-PVA [poly(ethylene glycol)-poly(vinyl alcohol) graft copolymer] solid dispersions with a 5 cm(3) table-top, twin-screw corotating microcompounder (DSM Xplore). Phase behavior of PEG-g-PVA, miscibility of mico…
The aim of this work is to describe the resistance of ultra high performance fibre reinforced concrete (UHPFRC) to projectile impact. The main goal is to find an optimum fibre content in the UHPFRC mixture with respect to the resistance to projectile impact, strength and workability. In addition, the authors describe…
The changes in fast dynamics of HP35 with a double CN vibrational dynamics label (HP35-P(2)) as a function of the extent of denaturation by urea were investigated with two-dimensional infrared (2D IR) vibrational echo spectroscopy. Cyanophenylalanine (PheCN) replaces the native phenylalanine at two residues in the hyd…
The reactivity of Cu monolayer (ML) and bilayer films grown on Ru(0001) towards O(2) and H(2) has been investigated. O(2) initial sticking coefficients were determined using the King and Wells method in the incident energy range 40-450 meV, and compared to the corresponding values measured on clean Ru(0001) and Cu(111…
Abstract A Pd‐modified hydrogen storage alloy was investigated as the anode electrocatalyst of direct borohydride fuel cell. The modification of the MmNi50.6 Co10.2 Mn5.4 Al1.2 hydrogen storage alloy with Pd was carried out by a self‐reduction reaction method. The morphology and the distribution of Pd on the surface o…
We measured the thermal conductivity of spinel MnV${}_{2}$O${}_{4}$ and Al-doped samples with an applied magnetic field, and they exhibited orbital and spin ordering at low temperatures. We found that the thermal resistivity (reciprocal thermal conductivity) in the orbital-disordered phase is enhanced when the system…
Shaping planner: Monodispersed Pt nanodecahedrons and nanoicosahedrons in high shape selectivities (>70 %) were synthesized by a general and facile solid–liquid interface mediated reduction method. The unique structure of the linear precursors with PtII chains possessing strong metal–metal interactions and their week-…
The basic conceptual idea is to use UHPFRC only in those zones of the structure where the outstanding UHPFRC properties in terms of durability and strength are fully exploited; i.e. UHPFRC is used to “harden” the zones where the structure is exposed to severe environmental conditions (f.ex., deicing salts, marine envi…
Abstract Since their first development in the 1960s, phase change (PC) memory materials have become essential components of optical memories (DVD‐RW, Blu‐ray Disc, …) used in countless households worldwide. They are now poised to play a decisive role in future non‐volatile computer memories. PC memory materials are re…
We have fabricated a series of thin (~50 nm) erbium-doped (by ion implantation) silicon-rich oxide films in the configuration that mitigates previously proposed mechanisms for loss of light emission capability of erbium ions. By combining the methods of optical, structural and electrical analysis, we identify the erbi…
A laterally azo-bridged trimer ferroelectric liquid crystal (FLC) incorporating a strong chromophore along its polar axis was synthesized and characterized by polarized-light optical microscopy, differential scanning calorimetry, two-dimensional X-ray diffraction analysis, electro-optical measurements, and nonlinear o…
The present article reports photophysical studies on supramolecular interaction of a zinc phthalocyanine derivative, namely, zinc-2,9,16,23-tetra-tert-butyl phthalocyanine (1) with C(60) and C(70) in solvents having varying polarity, i.e., toluene and 1,2-dichlorobenzene (DCB). The interesting feature of the present w…
We report a detailed density functional analysis of the spin exchange interactions and the magnetic structure of the high-temperature multiferroic CuBr${}_{2}$ and compare the results with magnetic susceptibility measurements. CuBr${}_{2}$ shows one-dimensional antiferromagnetism and undergoes long-range antiferromagn…
There is more than foam: Optical microscopy images (with false colouring, see picture) depicting quick destabilization (within minutes) of foamulsions due to the coalescence of densely-packed oil droplets when heated at higher temperatures (65 °C).
High-grade gliomas (glioblastomas) are the most common and deadly brain tumors in adults, currently with no satisfactory treatment available. Apart from de novo glioblastoma, it is currently accepted that these malignancies mainly progress from lower grade glial tumors. However, the molecular entities governing the pr…
Crystal structures of divalent metal-dependent pyruvate aldolase, HpaI, in complex with substrate and cleavage products were determined to 1.8-2.0 Å resolution. The enzyme·substrate complex with 4-hydroxy-2-ketoheptane-1,7-dioate indicates that water molecule W2 bound to the divalent metal ion initiates C3-C4 bond cle…
Dilute phosphoric acid pretreatment of moso bamboo materials was studied for producing high quality dissolving pulp for textile applications. The dynamics of dilute acid pretreatment were considered. The Saeman model was found to describe well the acid hydrolysis of moso bamboo hemicelluloses to their monomers under d…
Höchst einflussreich: Eine einzigartige diskontinuierliche Eigenschaft und eine aktive Phase wurden für Legierungskatalysatoren aus Ni und geordnetem Ce2Zr2Ox (x=7–8) bei der Methandampfreformierung beobachtet. Die katalytische Leistung von Ni/Ce2Zr2Ox hing erheblich von der Phase und dem Sauerstoffgehalt des Ce2Zr2Ox…
Abstract Photoluminescence (PL) of porous silicon (PSi) particles can be significantly enhanced in some organic solvents (i.e., ethanol or dimethyl sulfoxide) under microwave irradiation. Fourier transform infrared spectra, dynamic‐light‐scattering measurements, and scanning electron microscopy had been adopted to exp…
