ZnO/Al2O3 layered structures deposited by RF magnetron sputtering on glass: growth characteristics, optical properties, and microstructural analysis
(2021)
In this study, Al2O3 thin films of different thicknesses (50 nm, 100 nm, 150 nm, 200 nm, and 250 nm) were, first, grown using RF magnetron sputtering technique on glass substrate at 30 °C temperature, with 120Wpower value. ...
Modeling of Schottky diode characteristic by machine learning techniques based on experimental data with wide temperature range
(18 Ekim 20)
In this study, 4 common machine learning methods have been used to model the I–V characteristic of the Au/Ni/n-GaN/undoped GaN Schottky diode. The current values of previously produced Au/Ni/n-GaN/undoped GaN Schottky diode ...
A comparative study of hardness/scratch/wear properties of TiCN and TiAlN coatings on DIN 1.2842 steel by CA-PVD method
(2021)
In the present study, TiCN and TiAlN were deposited on DIN 1.2842 (AISI O2) steel, and their mechanical properties was compared by investigating coating thickness, adhesion strength, microhardness, and elastic modulus. To ...
A Novel and Eco‑friendly Approach for the Simultaneous Recovery of Copper and Diamond from Waste Cutting Segments via Electrodissolution/Deposition
(2021)
A new approach is brought to diamond recovery from waste cutting segments. Unlike the commonly used hydrometallurgical processes, this approach offers the simultaneous recovery of copper with diamond. Besides, instead of ...
The efect of microwave and ultrasound activation on the characteristics of biochar produced from tea waste in the presence of H3PO4 and KOH
(Springer, 14.08.2021)
The mechanism of chemical and physical activation during biomass pyrolysis is crucial for the more efective use of biomass
and the preparation of functional porous biochemical materials. In this study, raw tea waste (RTW) ...
Preparation and characterization of nanosized Fe3O4-biochar electrocatalysts with large surface area for H2O2 sensing
(Elsevier, Nisan 2022)
A nanoscale Fe3O4-biochar (Fe-BC) composite material was prepared using hazelnut shell (HNS) biochar and
FeCl2. Biochar was prepared by phosphoric acid (H3PO4)-assisted pyrolysis (BCA) and H3PO4 + microwave
(MW)-assisted ...
Mechanochemical Pretreatment for Waste-Free Conversion of Bamboo to Simple Sugars: Utilization of Available Resources for Developing Economies
(05.01.2022)
In this work, mechanochemical pretreatment of Bambusa vulgaris is evalu-ated for waste-free production of renewable sugars for subsequent fermen-tation. After a 60 min mechanochemical pretreatment followed by enzyme ...
Effects of Heavy Iodine Atoms and π-Expanded Conjugation on Charge Transfer Dynamics in Carboxylic Acid BODIPY Derivatives as Triplet Photosensitizers
(2022)
Borondipyrromethene (BODIPY) chromophores are composed of a functional-COOH group at meso position with or without a biphenyl ring, and their compounds with heavy iodine atoms at −2, −6 positions of the BODIPY indacene ...
Investigation of structural, morphology, and conduction mechanism of GO–Fe3O4–TiO2 composite material
(23.08.2023)
The graphene oxide composite (GO), iron oxide (Fe3O4), and titanium dioxide
(TiO2) were prepared by the sol–gel process. The surface of GO is coated with
TiO2 and Fe3O4 nanoparticles, and the composite contains 10.26% ...
Synthesis and characterization of molybdenum trioxide with an orthorhombic crystal structure for supercritical water gasification application
(01.03.2023)
Supercritical water (SCW) catalytic gasification is promising for the production of synthetic gas from biomass. However, maintaining the activity of heterogeneous catalysts under high pressure and hydrothermal conditions ...
