Modification of the existing polymers leads to improvement of many desirable properties. Hence, prepared hyperbranched polyurethane was modified with different amounts of bisphenol-A based epoxy resin. The modified system was cured by cycloaliphatic amine hardener at 120 °C for a specified period of time. The curing r…
Novel, highly stable Bi2S3 and Bi2−xMnxS3 quantum dots (QDs)–glass optical nanosystems were architectured successfully. These advanced nanosystems were characterized by High Resolution Transmission Electron Microscopy (HRTEM), UV-Vis-NIR spectroscopy and room temperature photoluminescence (PL) measurements. HRTEM of t…
The organic–inorganic hybrid charge-transfer salt of BETS and a two-dimensional oxalate–metalate: BETS3[Cu2(C2O4)3](CH3OH)2 (1) was obtained by the electrochemical oxidation of neutral BETS in the presence of [(C2H5)3NH]2Cu(C2O4)2 in a C6H5Cl–CH3OH solution. 1 crystallizes in a triclinic crystal system with cell param…
The radiation damage rates to crystals of 15 model macromolecular structures were studied using an automated radiation sensitivity characterization procedure. The diffracted intensity variation with dose is described by a two-parameter model. This model includes a strong resolution-independent decay specific to room-t…
In the present study, Fe2O3 was used as catalyst for the removal of NO in a hybrid plasma- catalytic reactor. The catalyst was located either directly inside the hybrid plasma-catalytic reactor or in a separate catalytic reactor, which followed ozone producing and injecting plasma reactor. Ozone production in such a r…
We have used Monte Carlo simulations to study the formation of the MCM-41 mesoporous silica material, with a new lattice model featuring explicit representations of both silicic acid condensation and surfactant self-assembly. Inspired by experimental syntheses, we have adopted the following two-step "synthesis" during…
Abstract Two new isostructural compounds, M 2 Cd 3 B 16 O 28 (M = Rb, Cs), have been synthesized by a high‐temperature solid‐state reaction for the first time. M 2 Cd 3 B 16 O 28 (M = Rb, Cs) crystallize in the monoclinic space group C 2/ c , with a = 21.4856(10) Å, b = 7.6852(4) Å, c = 13.3694(8) Å, β = 91.705(3)°, Z…
We perform charge self-consistent density functional theory combined with dynamical mean field theory calculations to study correlation effects on the Fermi surfaces of the iron pnictide superconductors LaFePO and LiFeP. We find a distinctive change in the topology of the Fermi surface in both compounds where a hole p…
Temperature-dependent photoemission spectroscopy in Li(0.9)Mo(6)O(17) contributes to evidence for one-dimensional (1D) physics that is unusually robust. Three generic characteristics of the Luttinger liquid are observed: power law behavior of the k-integrated spectral function down to temperatures just above the super…
Abstract An acrylamide‐type copolymer containing catechol, amino, and hydroxyl groups was synthesized as a mimetic of the natural mussel adhesive protein (MAP). The obtained copolymer in a phosphate buffer solution (pH = 8.0) formed a hydrogel within 2 h under air, whereas gelation did not proceed under argon atmosphe…
Nanosheets are a peculiar kind of nanomaterials that are grown two-dimensionally over a micrometer in length and a few nanometers in thickness. Wide varieties of inorganic semiconductor nanosheets are already reported, but controlling the crystal growth and tuning their thickness within few atomic layers have not been…
Poly(styrene-block-4-vinylpyridine) (PS-b-P4VP) nanospheres are prepared in an aerosol phase where the self-assembly is induced by initial solvent evaporation and subsequent thermal annealing. The block copolymers self-assemble into different structures within solid aerosol nanospheres depending on the relative length…
The effects of the pore properties and the ionic sizes on the electric double-layer capacitances have been investigated by using the monolithic carbon electrodes with different pore properties. The carbon monoliths with high surface areas which possess homogeneous pore properties in the whole monoliths were prepared f…
Gamma-ray energy absorption buildup factors of gaseous mixtures; neon (95%) + argon (5%), argon (95%) + acetylene (5%), argon (95%) + methane (5%), argon (95%) + carbon dioxide (5%), methane (70%) + pentane (30%) and argon (90%) + methane (10%) were studied by Geometrical Progression (G-P) fitting for the photon energ…
In the present work, we report on a chemical phase separation in crystalline superconducting K${}_{0.65}$Fe${}_{1.74}$Se${}_{2}$, investigated by means of magnetization experiments, scanning electron microscopy, electron backscatter diffraction, and energy-dispersive x-ray spectrometry. It is shown that the crystal co…
A new class of chiral and potentially biodegradable poly(ester–imide)s containing natural amino acids in the main chain was synthesized. In this investigation, N,N′-(3,3′,4,4′-benzophenonetetracarboxylic)-3,3′,4,4′-diimido-bis-(L-tyrosine methyl ester) as a novel diol and synthesized pyromellitic dianhydride-derived d…
In the present paper, YbVO4 microcrystals with diverse morphologies, sizes and dimensions have been synthesized via a mild and controllable hydrothermal process using trisodium citrate (Na3Cit) as an organic additive. The phases, morphologies, sizes, and photoluminescent properties of the as-prepared products were wel…
Fission gas retention or release has a critical impact on the function of advanced nuclear materials. Helium trapping in, and release from, radiation defects induced by neutrons and by \ensuremath{\alpha} decay in YSZ (yttria-stabilized zirconia) is experimentally simulated using synchronized Zr${}^{+}$ and He${}^{+}$…
Upon 808 nm excitation, an intense broadband near-infrared emission from Cr4+ has been observed in 80GeS2-20Ga2S3 chalcogenide glass-ceramics (GCs) containing Ga2S3 nanocrystals. The emission band peaking at 1250 nm covers the O, E, S bands (1000-1500 nm). The formation of Ga2S3 nanocrystals (∼20 nm) increases the emi…
Abstract The X‐ray structures and magnetic properties of three new iron(II) coordination polymers with the general formula [FeL1(L ax )] n are presented.
