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 ...
Half inverse problems for the impulsive quadratic pencil with the discontinouty coefficient
(Turkish Journal of Mathematics, 2021)
In this paper, we study the inverse spectral problem for the quadratic differential pencils with discontinuity
coefficient on [0, π] with separable boundary conditions and the impulsive conditions at the point x =

(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 New Enrichment Method for Quantification of 5-Hydroxymethylfurfural by Indirect Flame Atomic Absorption Spectrometry in Honey and Jam Samples
(OXFORD UNIV PRESS INCJOURNALS DEPT, 2001 EVANS RD, CARY, NC 27513, 2021)
Background: Because of increasing amounts of 5-hydroxymethylfurfural (5-HMF) in processed foods and the complexity of the matrix, monitoring of trace 5-HMF requires accurate and reliable methods. Hence, an efficient sample ...

Selective extraction and enrichment of 5-hydroymethylfurfural from honey, molasses, jam and vinegar samples prior to sensitive determination by micro-volume UV-vis spectrophotometry
(CADEMIC PRESS INC ELSEVIER SCIENCE525 B ST, STE 1900, SAN DIEGO, CA 92101-4495, 2021)
In this study, a new method was developed for the extraction/enrichment of 5-hydroxymethylfurfural (5-HMF) from sample matrix prior to analysis. The method is based on the selective formation of the imine adduct and ionpair ...
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 ...
