Total scattering data of nanocrystalline gahnite (ZnAl 2 O 4 , 2–3 nm) have been collected with three of the most commonly used instruments: (i) ID31 high-resolution diffractometer at the European Synchrotron Radiation Facility (ESRF) ( Q max = 22 Å −1 ); (ii) ID11 high-energy beamline at the ESRF ( Q max = 26.6 Å −1…
Crystal structures of the thermostable meso-diaminopimelate dehydrogenase (DAPDH) from Ureibacillus thermosphaericus were determined for the enzyme in the apo form and in complex with NADP(+) and N-tris(hydroxymethyl)methyl-2-aminoethanesulfonic acid. The main-chain coordinates of the enzyme showed notable similarity…
An approach is demonstrated for the manufacturing of a microfibrillated cellulose (MFC) composite paper. A key element in the manufacturing paradigm is the use of high consistency suspensions to improve retention and minimize the need for water removal after forming. The rheological characterization of the composite f…
The review of thermodynamic data of ruthenium oxides reveals large uncertainties in some of the standard enthalpies of formation, motivating the use of high-level relativistic correlated quantum chemical methods to reduce the level of discrepancies. The reaction energies leading to the formation of ruthenium oxides Ru…
We investigate quasiparticle band structures of rutile and anatase phases of ${\mathrm{TiO}}_{2}$ and cubic ${\mathrm{SrTiO}}_{3}$ using various levels of $GW$ approximations such as ${G}_{0}{W}_{0}, G{W}_{0}, GW, QPG{W}_{0}$, and $QPGW$. It is found that the quasiparticle band gap increases as the self-consistency le…
A straightforward multitemplate carbonization method for producing nanoporous carbons has been implemented using magnesium citrate as the carbon source and magnesium powder as the template. Notably, the crystallinities of the carbon materials were greatly enhanced with increasing carbonization temperatures. Sample C-4…
In this work, centimeter-scale macrocrystals of nonpolar colloidal quantum dots (QDs) incorporated into anthracene were grown for the first time. The exciton transfer from the anthracene host to acceptor QDs was systematically investigated, and anisotropic emission from the isotropic QDs in the anthracene macrocrystal…
Abstract α‐Form Co x Ni 1– x hydroxides with different Co/Ni ratios were synthesized by a chemical co‐precipitation method under mild conditions. The effects of Co/Ni ratio on the structure, morphology, and supercapacitive properties of α‐form Co x Ni 1– x hydroxides were investigated in detail. α‐Form Co x Ni 1– x hy…
In this study, the mutagenicity and genotoxicity of indium tin oxide (ITO) nanomaterial were assessed using two standard genotoxicity assays, the Salmonella reverse mutation assay (Ames test) and the in vitro micronucleus (MN) assay. Seven different concentrations (12.5, 25, 50, 75, 100, 125, and 150 µg/plate) of this…
The results of investigations of the phase composition, structural parameters, static and dynamic magnetic properties of BaCo 0.7 Zn 1.3 Fe 16 O 27 hexaferrites obtained by the method of self-propagation high-temperature synthesis in combination with mechanochemical activation and radiation-thermal post-sintering are…
By applying Eu3+/Tb3+-doped phosphate glass as photovoltaic (PV) precursors, the performance of conventional amorphous-silicon and multicrystalline silicon (mc-Si) PV solar cells was improved. Rare-earth glass absorbs light at ultraviolet bands and subsequently emit light at visible bands. The shorter wavelength of th…
Liquid crystal displays are playing a crucial role in current information era. Many of them are edgelit, where light is produced by a light source at the edge of the display and is spread out to illuminate the entire display through a light waveguide plate (LWGP). We developed a novel polarizing LWGP from polymer stab…
The strontium ferrite radiation-thermal synthesis process due to heating by intensive electron beam is described. The radiation-thermal and thermal strontium ferrite synthesis processes kinetics were studied and compared.
Directional driving of a droplet can be achieved on a gradient‐exhibiting, nanostructured microhump (GNMH) surface at low temperature and high humidity. The GNMH surface is fabricated using a commercial carbon fiber plate with an array of microscale hump structures; nanotechniques are used to form varying nanostructur…
In this study, we focus on refractive-index and Abbe-number improvements to optical polyesters. First, we modify polymers by introducing sulfonyl groups and removing phenyl groups in the monomer structure. In this manner, new polymers with Abbe numbers higher than 40 are synthesized. To further increase the refractive…
A (001)-epitaxial-BiFeO3/CoFe2O4 bilayer was grown by self-assembly on SrTiO3 (100) substrates by just coating a mixture precursor solution. The thickness ratio of the bilayer could be controlled by adjusting the composition ratio. For example, a BiFeOx:CoFe2Ox = 4:1 (namely Bi4CoFe6Ox) mixture solution could make a t…
In this work, new glass compositions were prepared in the ternary system GeO 2 – K 2 O – Ta 2 O 5 . Potassium oxide was added to reach the complete melt of the starting mixture and two composition series were investigated: the first one with a constant K 2 O molar content of 10% in the ternary system (90– x ) GeO 2 –1…
One of the promising systems to realize quantum computation is a hybrid system where a superconducting flux qubit plays the role of a quantum processor and the nitrogen-vacancy- $({\mathrm{NV}}^{\ensuremath{-}})$ center ensemble is used as a quantum memory. We have theoretically and experimentally studied the effect o…
Controlling the nature and size of cobalt(II) polynuclear precursors on γ-alumina and silica-alumina supports represents a challenge for the synthesis of optimal cobalt-based heterogeneous catalysts. By density functional theory (DFT) calculations, we show how after drying the interaction of cobalt(II) precursor on γ-…
Precise manipulation of water is a key step in numerous natural and synthetic processes. Here, a new flexible and transparent hierarchical structure is determined that allows ultra‐dexterous manipulation and lossless transfer of water droplets. A 3D nanomesh is fabricated in one step by scalable electrospinning of low…
