Portable low-cost open-source wireless spectrophotometer for fast and reliable measurements
(Elsevier Ltd, 2020)
We demonstrate a low-cost standalone portable spectrophotometer for fast and reliable measurement execution. The data acquired can be both displayed via a dedicated smartphone application or a computer interface, allowing ...
Identifying iron-bearing nanoparticle precursor for thermal transformation into the highly active hematite photo-fenton catalyst
(MDPI AG, 2020)
The hematite photo-Fenton catalysis has attracted increasing attention because it offers strong oxidation of organic pollutants under visible light at neutral pH. In the present work, aqueous synthesis of hematite photo-Fenton ...
Low temperature afterglow from SrAl 2 O 4 : Eu, Dy, B containing glass
(Acta Materialia Inc, 2021)
SrAl2O4: Eu, Dy, B particles were added in a phosphate glass (90NaPO3-10NaF (in mol%)) using the direct doping method. For the first time, the composition of the particles prior to and after embedding them in the glass was ...
Dynamics of Singlet Oxygen Molecule Trapped in Silica Glass, Studied by Luminescence Polarization Anisotropy and Density Functional Theory
(American Chemical Society, 2020)
The lowest excited electronic state of the O2 molecule, a1Δg, the "singlet oxygen", is of utmost importance for photochemistry and photobiology. For O2 trapped in silica glass, the lifetime of this state and the associated ...
The boron effect on low temperature luminescence of SrAl2O4:Eu, Dy
(Elsevier Ltd, 2020)
Temperature dependence of the afterglow of persistent luminescence material SrAl2O4:Eu,Dy is a major problem for outdoor low temperature applications. Therefore this publication deals with tailoring the material for better ...
Synthesis and characterization of GaN/ReS2, ZnS/ReS2 and ZnO/ReS2 core/shell nanowire heterostructures
(Elsevier B.V., 2021)
Layered 2D van der Waals (vdW) materials such as graphene and transition metal dichalcogenides have recently gained a great deal of scientific attention due to their unique properties and prospective applications in various ...
Antibacterial Activity of Positively and Negatively Charged Hematite (α-Fe2O3) Nanoparticles to Escherichia coli, Staphylococcus aureus and Vibrio fischeri
(MDPI, 2021)
In the current study, the antibacterial activity of positively and negatively charged spherical hematite (α-Fe2O3) nanoparticles (NPs) with primary size of 45 and 70 nm was evaluated against clinically relevant bacteria ...
Gallium Concentration Optimisation of Gallium Doped Zinc Oxide for Improvement of Optical Properties
(De Gruyter, 2021)
The near-band luminescence of doped ZnO is promising for advanced scintillators; however, the dopant type and concentration effects require a detailed study. Undoped and Ga-doped ZnO nanopowders were prepared by a ...
Membrane-less amphoteric decoupled water electrolysis using WO3 and Ni(OH)2 auxiliary electrodes
(Royal Society of Chemistry, 2022)
Energy storage and delivery play a crucial role in the effective management of renewable power sources such as solar and wind. Hydrogen energy is proposed to be one of the major substitutes to fill the gap between the ...
Magnetotransport Studies of Encapsulated Topological Insulator Bi2Se3 Nanoribbons
(MDPI, 2022)
The majority of proposed exotic applications employing 3D topological insulators require high-quality materials with reduced dimensions. Catalyst-free, PVD-grown Bi2Se3 nanoribbons are particularly promising for these ...
