Tuning the Photoresponse of Nano-Heterojunction: Pressure-Induced Inverse Photoconductance in Functionalized WO3 Nanocuboids
(John Wiley and Sons Inc., 2019)
Inverse photoconductivity (IPC) is a unique photoresponse behavior that exists in few photoconductors in which electrical conductivity decreases with irradiation, and has great potential applications in the development of ...
Low temperature X-ray absorption spectroscopy study of CuMoO4 and CuMo0.90W0.10O4 using reverse Monte-Carlo method
(Elsevier Ltd, 2019)
Reversible thermochromic phase transition between α- and γ-phases was studied in CuMoO4 and CuMo0.90W0.10O4 using X-ray absorption spectroscopy in the temperature range of 10–300 K. Reverse Monte Carlo modelling with ...
Ab initio calculations of Li2(Co, Mn)O8 solid solutions for rechargeable batteries
(World Scientific Publishing Co. Pte Ltd, 2019)
Current commercially available rechargeable Li-ion batteries, for example LiCoO2, are working mostly in the 4 V regime. One often suggested possibility to improve the effectivity of Li-ion batteries are the creation of the ...
Electronic processes in doped ZnO nanopowders
(Institute of Physics Publishing, 2019)
ZnO nanocrystals, undoped and doped with Iridium or Indium were prepared by solar irradiation in Heliotron reactor in PROMES CNRS facilities, France. The comparative analysis of the excitonic spectra of ZnO single crystal ...
Afterglow, TL and OSL properties of Mn2+-doped ZnGa2O4 phosphor
(Nature Publishing Group, 2019)
Zinc gallate (ZnGa2O4) spinel ceramics doped with Mn2+ ions was prepared by a solid-state reaction at 1200 °C in air. Manganese concentration was equal to 0.05 mol.% of MnO with respect to ZnO. Ceramics produced in this ...
Abrupt elastic-to-plastic transition in pentagonal nanowires under bending
(Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2019)
In this study, pentagonal Ag and Au nanowires (NWs) were bent in cantilever beam configuration inside a scanning electron microscope. We demonstrated an unusual, abrupt elastic-to-plastic transition, observed as a sudden ...
Computer Simulations of the Band Structure and Density of States of the Linear Chains of NaCl Ions
(Sciendo, 2019)
The paper presents the results of first-principles computer simulations of the band structure, the density of states, and the total energy of NaCl (NaCl, Na2Cl2, Na3Cl3, Na4Cl4, Na6Cl6) linear chains of atoms. Modelling ...
Enhancement of photosensitivity in azo-epoxy resists for direct holographic recording
(National Institute of Optoelectronics, 2019)
Azo-epoxy resist is promising material for direct holographic recording due to good photosensitivity and possibility to modify structure of molecule during synthesis – obtained polymer polymerization index easily can be ...

First-Principles Evaluation of the Morphology of WS2 Nanotubes for Application as Visible-Light-Driven Water-Splitting Photocatalysts
(American Chemical Society, 2019)
One-dimensional tungsten disulfide (WS2) single-walled nanotubes (NTs) with either achiral, i.e., armchair (n, n) and zigzag-type (n, 0), or chiral (2n, n) configuration with diameters dNT > 1.9 nm have been found to be ...
