The fresnoite-type compound Sr2TiO(Si2O7), distrontium oxidotitanium disilicate, has been prepared by high-temperature solid-state synthesis. The results of a Rietveld refinement study, based on high-resolution synchrotron X-ray powder diffraction data, show that the title compound crystallizes in the space group P4bm…
Hierarchical core–corona porous γ-Al2O3 nanostructures have been synthesized through the reaction of toluene diluted TMA with water by controlling the methane leaching. The obtained γ-Al2O3 core–corona nanostructures exhibit high thermal stability and excellent performance for polluted water treatment.
The chiroptical, linear, and second-order nonlinear optical (NLO) properties of chiral mononuclear and dinuclear zinc complexes have been investigated for the first time at density functional theory level. The calculated electron absorption energies and oscillator strengths are in reasonable agreement with the experim…
ZnO/MgZnO quantum-well (QW)-based light-emitting diodes using the metal–insulator–semiconductor (MIS) structure have been demonstrated and characterized in this study. ZnO near-band-edge UV emission peaked at ∼372 nm is observed at room temperature and the average energy conversion efficiency is obtained about 0.51%.…
The existence of a shadow Hamiltonian H̃ for discrete classical dynamics, obtained by an asymptotic expansion for a discrete symplectic algorithm, is employed to determine the limit of stability for molecular dynamics (MD) simulations with respect to the time-increment h of the discrete dynamics. The investigation is…
The electronic and vibrational properties of EuFe(2)As(2) in the tetragonal phase between 0 and 5 GPa have been investigated using (57)Fe Mössbauer spectroscopy and (57)Fe nuclear resonance inelastic scattering, respectively. We find a discontinuous increase of the center shift around 2.3 GPa, reflecting a change of t…
This paper describes the use of an electrochemical Hull type cell adapted for protein crystallization evaluating three inclination angles (45°, 60° and 90°). For optimization experiments, classical platinum wire electrodes were used and once the best geometry was known, they were replaced with 0.5 mm diameter low-cost…
Herein we systematically probed the atom-leaching mechanism of Pd nanoparticle-driven Stille coupling to further elucidate the fate of the highly active Pd0 atoms released in solution. In this regard, initial oxidative addition at the particle surface results in Pd atom abstraction for reactivity in solution. As a res…
Abstract A series of amphiphilic graft copolymers based on polyaspartamide were synthesized by successive aminolysis reactions of polysuccinimide using 2‐diisopropylaminoethyl ( DIP ), O ‐(2‐aminoethyl)‐ O ′‐methylpolyethylene glycol ( PEG ) and lauryl amine as pH ‐sensitive, hydrophilic and hydrophobic groups, respec…
In a solid-oxide fuel cell (SOFC), a thermoelectric material used as the cathode can generate extra electric power from the temperature gradient caused by the cell ohmic energy loss. Such a thermoelectric SOFC is an effective strategy to enhance the efficiency of fuel utilization by consuming waste heat. In this work,…
Abstract For the epoxidation of cyclooctene with hydrogen peroxide (H 2 O 2 ), the catalytic activity of a dinuclear peroxotungstate, [{WO(O 2 ) 2 } 2 (μ‐O)] 2– , is strongly dependent on additives, and HClO 4 is the most effective. The reaction of [{WO(O 2 ) 2 } 2 (μ‐O)] 2– with HClO 4 (0.5 equiv.) gives a protonated…
We find remarkably strong absorption due to magnetic polarization in common colloidal and lithographic metallic nanoparticles. Our analysis is based upon a thorough examination of the dipolar electric and magnetic polarizabilities for representative combinations of nanoparticle composition, size, and morphology. We il…
Wood fiber/poly(lactic acid) composites with 70 wt% wood fiber were prepared using a super mixing-hot press method. The biodegradability of composite panels made with one unmodified and three types of modified poly(lactic acid) was evaluated by comparing the mechanical strength, molecular weight, thermal properties an…
Abstract Polyoxometalates (POMs) are anionic metal oxides and encompass a diverse family of nanosized compounds with an unmatched range of architectures and physical properties. The use of the pyramidal sulfite anion, with its numerous coordination modes, has introduced structural diversity into the POM‐based chemical…
At present, intensive investigation aims at the creation of optimal valvular prostheses. We introduced and tested the applicability and functionality of two advanced cell-plus-matrix seeding technologies, spray-assisted bioprocessing (SaBP) and laser-assisted bioprocessing (LaBP), for autologous tissue engineering (TE…
We present studies of the photoelectrochemical characteristics and interfacial charge transfer dynamics of two (4,4′-difluoro-4-bora-3a,4a-diaza-s-indacene) BODIPY dyes (BODIPY-1 and 2) attached to nanostructured TiO2 electrodes. BODIPY-1 bears two carboxylic acid groups at its 2 and 6 positions and BODIPY-2 is modifi…

The Compressed Baryonic Matter experiment at the future Facility for Antiproton and Ion Research will use a time-of-flight (TOF) wall for hadron identification, based on the MRPC technology. The wall will be placed at 10m distance from the target covering an area on the order of 150m 2 . We propose here a realistic de…
The role of the Hf nanoclusters as near-UV, nanosecond-pulse laser-damage initiators in HfO<sub>2</sub> and SiO<sub>2</sub>-pair–based multilayer coatings remains speculative. In this work we use photothermal heterodyne imaging (PHI) to investigate absorption in HfO<sub>2</sub> and SiO<sub>2</sub> monolayers containin…
