In Situ Study of Zinc Peroxide Decomposition to ZincOxide by X-Ray Absorption Spectroscopy and ReverseMonte Carlo Simulations
(Wiley, 2022)
The Zn K-edge X-ray absorption spectroscopy is used to investigate in situ the decomposition of zinc peroxide ((Formula presented.)) to zinc oxide (ZnO). Principal component and linear combination analyses of the extended ...
Metal–Organic Frameworks (MOFs) Containing Adsorbents for Carbon Capture
(MDPI, 2022)
In this study, new composite materials of montmorillonite, biochar, or aerosil, containing metal–organic frameworks (MOF) were synthesized in situ. Overall, three different MOFs—CuBTC, UTSA‐16, and UiO‐66‐BTEC—were used. ...
Ab Initio Computations of O and AO as well as ReO2, WO2 and BO2-Terminated ReO3, WO3, BaTiO3, SrTiO3 and BaZrO3 (001) Surfaces
(MDPI, 2022)
We present and discuss the results of surface relaxation and rumpling computations for ReO3, WO3, SrTiO3, BaTiO3 and BaZrO3 (001) surfaces employing a hybrid B3LYP or B3PW description of exchange and correlation. In ...
A non-enzymatic electrochemical hydrogen peroxide sensor based on copper oxide nanostructures
(Beilstein-Institut, 2022)
This article describes the synthesis of nanostructured copper oxide on copper wires and its application for the detection of hydrogen peroxide. Copper oxide petal nanostructures were obtained by a one-step hydrothermal ...
Microwave-assisted synthesis and characterization of undoped and manganese doped zinc sulfide nanoparticles
(Elsevier, 2022)
Undoped and Mn-doped ZnS nanocrystals were produced by the microwave-assisted solvothermal method and characterized by X-ray diffraction, photoluminescence spectroscopy and scanning electron microscopy with energy-dispersive ...
Liquid-assisted grinding/compression: a facile mechanosynthetic route for the production of high-performing Co–N–C electrocatalyst materials
(Royal Society of Chemistry, 2022)
Worldwide implementation of energy conversion devices such as metal–air batteries and fuel cells needs an innovative approach for the sustainable design of noble metal-free electrocatalysts. A key factor to be considered ...
CO2 and CH2 Adsorption on Copper-Decorated Graphene: Predictions from First Principle Calculations
(MDPI, 2022)
Single-layer graphene decorated with monodisperse copper nanoparticles can support the size and mass-dependent catalysis of the selective electrochemical reduction of CO2 to ethylene (C2 H4 ). In this study, various active ...
Experimental Confirmation of C-Rate Dependent Minima Shifts in Arrhenius Plots of Li-Ion Battery Aging
(The Electrochemical Society, 2022)
Li-ion batteries show a minimum of their aging rate at a certain temperature. This minimum in the corresponding Arrhenius plot expresses the longest cycle life at a certain C-rate. By characterizing aging of laboratory-made ...
Ion-Track Template Synthesis and Characterization of ZnSeO3 Nanocrystals
(MDPI, 2022)
ZnSeO3 nanocrystals with an orthorhombic structure were synthesized by electrochemical and chemical deposition into SiO2/Si ion-track template formed by 200 MeV Xe ion irradiation with the fluence of 107 ions/cm2 . The ...
Synthesis, structural and luminescent properties of Mn-doped calcium pyrophosphate (Ca2P2O7) polymorphs
(Nature Research, 2022)
In the present work, three different Mn2+-doped calcium pyrophosphate (CPP, Ca2P2O7) polymorphs were synthesized by wet co-precipitation method followed by annealing at different temperatures. The crystal structure and ...
