Chemical-state analyses of Ni, Zn, and W ions in NiWO4–ZnWO4 solid solutions by X-ray photoelectron spectroscopy
(Elsevier, 2022)
The chemical states of Ni, Zn, and W in microcrystalline NiWO4–ZnWO4 solid solutions were studied by X-ray photoelectron spectroscopy. The recorded spectra of the Ni 2p, Zn 2p, and W 4f photoelectron lines and Ni L2M23M45, ...
Kinking in Semiconductor Nanowires: A Review
(American Chemical Society, 2022)
The growth direction of nanowires (NWs) can change during synthesis as a result of stochastic processes or modulation of certain growth conditions. This phenomenon is known as kinking. Although deviations from a uniform ...
High-pressure synthesis of boron-rich chalcogenides B12S and B12Se
(Elsevier, 2022)
Two boron-rich chalcogenides B12S and B12Se isostructural to α-rhombohedral boron were synthesized by chemical reaction of the elements at high-pressure – high-temperature conditions. The crystal structures and stoichiometries ...
Pulsed Electric Fields Alter Expression of NF-κB Promoter-Controlled Gene
(MDPI, 2022)
The possibility to artificially adjust and fine‐tune gene expression is one of the key mile-stones in bioengineering, synthetic biology, and advanced medicine. Since the effects of proteins or other transgene products ...
Unraveling the Structure and Properties of Layered and Mixed ReO3–WO3 Thin Films Deposited by Reactive DC Magnetron Sputtering
(American Chemical Society, 2022)
Tungsten trioxide (WO3) is a well-known electrochromic material with a wide band gap, while rhenium trioxide (ReO3) is a “covalent metal” with an electrical conductivity comparable to that of pure metals. Since both WO3 ...
Sol-gel assisted molten-salt synthesis of novel single phase Y3–2xCa2xTaxAl5−xO12:1%Eu garnet structure phosphors
(Elsevier Ltd, 2022)
Strong absorption and emission are the key the features of any phosphor. The results obtained during this study demonstrate the difficulty of the incorporation of tantalum ions into the garnet structure and reveal that ...

Photophysical and Electrical Properties of Highly Luminescent 2/6-Triazolyl-Substituted Push-Pull Purines
(American Chemical Society, 2022)
New push-pull N(9)-alkylated 6-piperidino-2-triazolylpurine and 2-piperidino-6-triazolylpurine derivatives are synthesized, and their optical and optoelectronic properties are comprehensively characterized with experimental ...
Effects of Electron Correlation inside Disordered Crystals
(MDPI, 2022)
We propose a novel approach for characterising the electron spectrum of disordered crystals constructed from a Hamiltonian of electrons as well as phonons and a diagram approach for Green’s function. The system’s electronic ...
