We examine the structural and electronic properties of LaNiO${}_{3}$ and NdNiO${}_{3}$ epitaxial thin films grown on cubic (001) SrTiO${}_{3}$ from the viewpoint of bulk crystal symmetry and misfit strain. X-ray scattering and polarization-dependent x-ray absorption spectroscopy measurements are performed to determine…
In order to obtain high thermal conductivity materials for efficient heat sink applications, diamond particles dispersed CuB alloy matrix composites (CuB/diamond composites) containing diamond as high as 90 vol.% were produced by a high temperature–high pressure infiltration method. The thermal conductivity of the C…
Cu2O is an interesting semiconductor with extraordinary high exciton binding energy, however exhibiting weak room temperature excitonic luminescence. The issue was addressed in literature emphasizing a detrimental role of native point defects responsible for optical quenching. Resolving the problem, we propose a metho…
Sr 2– y – z Ca z Si(O 1– x N x ) 4: y Eu 2+ (SCSON:Eu 2+ ) solid solutions were prepared by substituting N 3-, Eu 2+, and Ca 2+ ions into Sr 2 SiO 4 (SSO). These ions contributed differently to the evolution of luminescence of SCSON:Eu 2+ . SSON:Eu 2+ ( z = 0) has two activation centers: Eu(I) and Eu(II). The nitridat…
Bi 2 O 3 thin films deposited by RF magnetron sputtering have been studied in situ by using photoelectron spectroscopy. UV/VIS transmission spectroscopy and XRD measurements were carried out to determine the optical and structural properties of the films. Thin film solar cells were built up with ITO|Bi 2 O 3 |Au layer…
Ionothermal reaction of DyCl3·6H2O with 1,4-benzenedicarboxylic acid (H2BDC) in 1-ethyl-3-methylimidazolium bromide (EMIM-Br) leads to a novel compound {(EMIM)[Dy3(BDC)5]}n (1). Compound 1 consists of the extraframework charge-balancing cation [EMIM]+ and the [Dy3(BDC)5]nn− anionic framework with hex topology. The 3D…
Aliphatic polyesters poly (ε-caprolactone) (PCL) and foam plastic have been shown to be biodegradable by microorganisms, which possess cutinolytic enzymes. Pseudozyma japonica-Y7-09, showed both high growth and enzyme activity on Yeast malt (YM) medium fed with PCL film than on YM medium. The hydrolytic enzyme activit…
The kinetic Monte Carlo simulation was used to predict the characteristics of the polymer network formation during pre- and postgelation regimes of free-radical cross-linking copolymerization. The simulation naturally considers the presence of multiradicals, primary and secondary cyclization with no preassumptions. Th…
The paper presents results of ab initio modelling of formation energies of vacancy–hydrogen complexes VHn and an extended variant of thermodynamic theory describing equilibrium concentrations of such complexes. A single H atom is shifted from vacancy to a neighbouring O-site by 1.19 Å. Two H atoms in a vacancy form a…
We investigate the electric field-induced assembly of Janus colloids composed of silica rods patterned with gold patches in both side- and tip-coated motifs. These shape and chemically anisotropic particles assemble into reconfigurable chains, whose structure depends on patch location, AC electric field strength, and…
Phthalocyanines (Pc) are dyes in widespread use in materials science and nanotechnology, with numerous applications in medicine, photonics, electronics and energy conversion. With the aim to construct biohybrid materials, we here prepared and analyzed the structure of two Pc-loaded virus-like particles (VLP) with diam…
Zn 1– x Mn x O nanostructures were synthesized via the microwave-assisted hydrothermal method, which rapidly produces particles of controlled size and morphology. Samples were analyzed considering the effects of manganese ion concentration. XRD revealed that all samples had wurtzite-type structure with Mn 2+ ions inco…
In this paper, the removal of congo red (CR) dye by adsorption on coinage nanoparticles [silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs)] coated activated carbon (AC) has been discussed. The effect of various process parameters has been investigated by following the adsorption technique. Equilibrium adsorp…
Besser als die Natur: In einem Hybridkatalysator bestehend aus Lipase B aus Candida antarctica und einer Nanopalladiumspezies in mesoporösem Siliciumoxid befinden sich die Metallnanopartikel und das Enzym in den Hohlräumen des Trägers in unmittelbarer Nähe. Der Katalysator ahmt ein Metalloenzym nach und ermöglichte di…
A novel linear-dendron-like polyampholyte, poly(L-lysine)-b-D2-poly(L-glutamic acid) [PLL-b-D2-(PLGA)4], where D2 is the second generation of poly(amido amine), was prepared by hydrolyzing poly(ε-benzyloxycarbonyl-L-lysine)-b-D2-poly(γ-benzyl-L-glutamate) copolymer which was synthesized via a combination of ring-openi…
Mussel-inspired synthetic poly(dopamine) thin films from dihydroxyphenylalanine (DOPA) and lysine, structurally similar to natural melanin, have drawn extensive interest as a versatile surface functionalization and coating material for use in a broad range of applications. In order to gain a better understanding of it…
The role of surface and subsurface O vacancies for gold adsorption on crystalline CeO2(111) films has been investigated by scanning tunneling microscopy and density functional theory. Whereas surface vacancies serve as deep traps for the Au atoms, subsurface defects promote the formation of characteristic Au pairs wit…
Supramolecular gelators comprising 1,3,5-benzenetricarboxylic acids and amino acid methyl esters (glycine, L-alanine, L-valine, L-leucine, L-methionine, and L-phenylalanine) for ionic liquids were developed. Ten types of ionic liquids were gelated using the above-mentioned gelators at relatively low concentrations. Fi…
A new tellurium-substituted Lindqvist-type polyoxoniobate [H2TeNb5O19](5-) was synthesized as a tetramethylammonium salt. When irradiated with a Xe lamp, a water-methanol solution of this cluster showed exceptionally high H2-evolution activity suggesting cocatalysis by the hexaniobate cluster and metallic tellurium, b…
This work investigates the application of ultrasound for improving the antisolvent crystallization of benzoic acid. The main objective of applying ultrasound is to enhance the crystal productivity and modify the morphology as compared to the conventional stirred crystallizer. The effect of the sonication on the crysta…
