Syntheses, crystal structures, hirshfeld surface analyses and electrochemical etoposide/camptotechin sensor applications of acetaldehyde oxime derivatives
(Elsevier, 2022)
(E)-2-(4-Hydroxyphenyl)-2-oxoacetaldehyde oxime monohydrate (I) and (E)-2-(4 Nitropheny1)-2oxoacetaldehyde oximes (II) were synthesized from 4'-hydroxyacetophenone and 4'-nitroacetophenone, respectively. Their structures ...
Comparative analysis of energy costs of asymmetric vs symmetric encryption-based security applications
(IEEE, 2022)
Public key algorithms are heavily used in many digital applications including key establishment schemes, secure messaging apps, and digital signature schemes in cryptocurrencies. Recent developments in the field of quantum ...
Characterization of macro mechanical properties and microstructures of cement-based composites prepared from fly ash, gypsum and steel slag
(MDPI, 2022)
Using solid wastes (SWs) as backfilling material to fill underground mined-out areas (UMOAs) solved the environmental problems caused by SWs and reduced the backfilling cost. In this study, fly ash (FA), gypsum and steel ...
Editorial: Advances in the design and implementation of cementitious backfills
(Frontiers Media, 2022)
Backfill plays an essential role in the most modern mining industries worldwide. It is usually applied
in the cementitious form to fill underground mined-out openings (stopes and/or voids)
Electrochemical properties of coumarin 500 encapsulated in a liquid crystal guided electrospun fiber core and their supercapacitor application
(Amer Chemical Soc., 2022)
Here, we first report a study on coumarin 500 and liquid crystal including polyacrylonitrile nanofibers in terms of synthesis, characterizations, and supercapacitor performances. SEM, POM, FTIR, and DSC measurements showed ...
Assessment of the thermo-hydraulic efficiency of an indoor-designed jet impingement solar thermal collector roughened with single discrete arc-shaped ribs
(MDPI, 2022)
This study illustrates the impact of single discrete arc-shaped ribs (SDASR)-type artificial roughness on the performance of a jet impingement solar thermal collector (JISTC). The impact of parametric variations of SDASR ...
Prospects and challenges of renewable energy-based microgrid system in Bangladesh: a comprehensive review
(Springer, 2022)
Global energy demand is continuously increasing where the pollution and harmful greenhouse gases that originated from the burning of fossil fuels are alarming. Various policies, targets, and strategies are being set to the ...
A comprehensive review on recent advancements in cooling of solar photovoltaic systems using phase change materials
(Oxford University, 2022)
Due to the increasing demand for energy worldwide, photovoltaic (PV) cooling systems have become an important field of research in recent years. The most important factor affecting the performance of a solar PV cell is its ...
Strength, acoustic, and fractal behavior of fiber reinforced cemented tailings backfill subjected to triaxial compression loads
(Elsevier, 2022)
Overall, solid materials like CTB (i.e., cemented tailings backfill) give out low-level seismic signals as they are under stress in underground mining applications involving ground control, rock burst, and coal bump ...
On the plane receding contact between two functionally graded layers using computational, finite element and artificial neural network methods
(Wiley, 2022)
The frictionless double receding contact problem for two functionally graded (FG) layers pressed by a uniformly distributed load is addressed in this paper. The gradation in the layers is assumed to follow an exponential ...
