Certain doping concentrations caused half-metallic graphene
(Elsevier B.V., 2017)The singly B and N doped graphene systems are carefully studied. The highly concentrated dopants cause a spin polarization effect in the systems. The spin polarization limits are affirmed in the singly B and N doped graphene ... -
Challenges in automated estimation of capillary refill time in dogs
(SPIE, 2018-02-20)Capillary refill time (CRT) is a part of the cardiorespiratory examination in dogs. Changes in CRT can reflect pathological conditions like shock or anemia. Visual CRT estimation has low repeatability; therefore, optical ... -
Changes in freshwater sediment microbial populations during fermentation of crude glycerol
(Pontificia Universidad Catolica de Valparaiso, 2021)Background: This work studied how the exposure to an unusual substrate forced a change in microbial populations during anaerobic fermentation of crude glycerol, a by-product of biodiesel production, with freshwater sediment ... -
Changes in structure and conduction type upon addition of Ir to ZnO thin films
(Elsevier B.V., 2017)Zn-Ir-O (Zn/Ir ≈ 1/1) thin films have been reported to be a potential p-type TCO material. It is, however, unknown whether it is possible to achieve p-type conductivity at low Ir content, and how the type and the magnitude ... -
Chapter 8: EPR in glass ceramics
(Elsevier B.V., 2019)The development of novel materials requires a profound understanding of the relationship between a material's performance and its structural properties. Electron paramagnetic resonance (EPR) is a well-established technique ... -
Characterization of CdxTeyOz/CdS/ZnO Heterostructures Synthesized by the SILAR Method
(MDPI, 2023)CdxTeyOz/CdS/ZnO heterostructures were obtained by the SILAR method using ionic electrolytes. A CdS film was formed as a buffer layer for better adhesion of the cadmium-tellurium oxides to the substrate surface. In turn, ... -
Characterization of crystalline structure and morphology of Ga2O3 thin film grown by MOCVD technique
(Trans Tech Publications Ltd., 2017)Growth of gallium oxide thin film was realized with MOCVD on (0001) sapphire substrate. Structural and compositional properties of thin film were studied employing trimethylgallium and water as precursors, carrier gases ... -
Characterization of electrospun poly(lactide) composites containing multiwalled carbon nanotubes
(SAGE Publications Inc., 2019)The main aim of this work was to obtain conductive polymer-based materials by incorporation of different amounts of multiwalled carbon nanotubes (MWCNTs) into poly(lactide)(PLA) using the electrospinning technique. Fiber-based ... -
Characterization of Mechanical Oscillations in Bismuth Selenide Nanowires at Low Temperatures
(MDPIO, 2023)A single transistor preamplifier circuit was designed to facilitate electrical detection of mechanical oscillations in nanoelectromechanical systems (NEMSs) at low temperatures. The amplifier was integrated in the close ... -
Characterization of Structural Stability of Magnetron Sputtered Tungsten-boron Thin Films at Elevated Temperatures
(Kaunas University of Technology, 2023)In the divertor of the tokamak type fusion reactors tungsten and tungsten-covered plasma facing materials are currently among the selected materials. However, metallic, high-Z plasma facing materials require plasma mitigation. ... -
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, ... -
Chlorine Adsorption on TiO2(110)/Water Interface: Nonadiabatic Molecular Dynamics Simulations for Photocatalytic Water Splitting
(MDPI, 2023)Chloride is one of the most abundant ions in sea water, which is more available than fresh water. Due to lack of H2O adsorbate states near the valence band maximum (VBM) edge, the difficulty of water dissociation incidents ... -
