Glass-forming nonsymmetric DWK-dyes with 5,5,5-triphenylpentyl and piparazine moieties for light-amplification studies
(SPIE, 2018)A series of 2,6-bis-styryl-4H-pyran-4-ylidene fragment containing glass-forming organic compounds with bonded amorphous phase promoting bulky triphenyl moieties through piperazine structural fragment [2-(2-(4-(bis(2-(tri ... -
Glyphosate Sensor Based on Nanostructured Water-Gated CuO Field-Effect Transistor
(MDPI, 2022)This research presents a comparative analysis of water-gated thin film transistors based on a copper oxide (CuO) semiconductor in the form of a smooth film and a nanostructured surface. A smooth CuO film was deposited ... -
Grain Boundary Wetting Phenomena in High Entropy Alloys Containing Nitrides, Carbides, Borides, Silicides, and Hydrogen: A Review
(MDPI, 2021)In this review, we analyze the structure of multicomponent alloys without principal components (they are also called high entropy alloys—HEAs), containing not only metals but also hydrogen, nitrogen, carbon, boron, or ... -
Grain growth in Na0.5Bi0.5TiO3-based solid solutions
(Taylor and Francis Ltd., 2019)This paper discusses effects of different dopants, sintering technique and parameters on microstructure and properties of pure and Yb, Er-doped Na0.5Bi0.5TiO3 (NBT). All stoichiometric compositions follow the abnormal grain ... -
Graphene Hybrid Metasurfaces for Mid-Infrared Molecular Sensors
(MDPI, 2023)We integrated graphene with asymmetric metal metasurfaces and optimised the geometry dependent photoresponse towards optoelectronic molecular sensor devices. Through careful tuning and characterisation, combining ... -
Growth and characterization of PbI2-decorated ZnO nanowires for photodetection applications
(Elsevier B.V., 2020)In this study, we demonstrated for the first time the growth of ZnO nanowires (NWs) decorated with highly crystalline few-layer PbI2 and fabricated two-terminal single-nanowire photodetector devices to investigate the ... -

Hardening of Steel Perforated Tape by Nd:YAG Laser
(Trans Tech Publications Ltd., 2017)One of the directions of application of the perforated metal material is their use as cutting elements in the production of processing tools. In this case it is necessary to carry out hardening of cutting surfaces to ... -
Hardness and modulus of elasticity of atomic layer deposited Al2O3-ZrO2 nanolaminates and mixtures
(Elsevier B.V., 2020)Atomic layer deposition was used to produce 90–105 nm thick alumina-zirconia mixtures and nanolaminate structures on soda-lime glass substrate. The resultant chemical and structural compositions of the thin films were ... -
Heat capacity and thermal conductivity of multiferroics Bi1-xPrxFeO3
(Taylor and Francis Ltd., 2019)The heat capacity and thermal conductivity of multiferroics Bi1–xPrxFeO3 (0 ≤ x ≤ 0.50) has been studied in the temperature range of 130–800 K. A slight substitution of praseodymium for bismuth is found to lead to a ... -
Heritage-making: Written Texts in the Transmission of Traditional Knowledge of Natural Dyeing
(The Museum of the Romanian Peasant Anthropology, 2022)Natural dyeing is an element of intangible cultural heritage which is gaining new relevance today. Heritage-making as a set of purposeful activities has become an object of interest for researchers relatively recently, ... -
High Entropy Alloys for Energy Conversion and Storage: A Review of Grain Boundary Wetting Phenomena
(MDPI, 2022)The multicomponent alloys with nearly equal concentration of components, also known as high entropy alloys (HEAs), were first proposed 22 years ago. The HEAs quickly became very important in materials science due to their ... -
