Synthesis and acetylcholinesterase enzyme inhibition properties of axially disubstituted silicon phthalocyanines and their quaternized derivatives
(Elsevier, 2022)
In this paper, axial 1,3-bis[4-(4-acetylpiperazin-1-yl)phenoxy]propanoxy and {2-[4-(4-acetylpiperazin-1-yl)phenoxy]ethoxy}ethoxy groups substituted silicon(IV) phthalocyanines ( PP-D-Si, PP-OH2-Si) and their quaternized ...
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 ...
A panel hidden cointegration analysis on the political stability and tourism receipts
(Taylor & Francis Ltd., 2022)
In the present study, the asymmetric relationships between political stability and tourism receipts in 14 MENA countries were investigated using panel data analysis with annual data of the period between 2002 and 2018. For ...
Metallo-phthalocyanines containing triazole substituents: Synthesis, spectroscopic and photophysicochemical properties
(Taylor & Francis Ltd., 2022)
Magnesium(II) (4), lead(II) (5) and zinc(II) (6) phthalocyanines were prepared. The structures of 4-6 were confirmed by the spectroscopic characterization such as FT-IR, H-1-NMR, MALDI-TOF mass, UV-vis and fluorescence ...
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 ...
Synthesis of novel thiosemicarbazone derivatives as antidiabetic agent with enzyme kinetic studies and antioxidant activity
(Taylor & Francis Ltd., 2022)
Novel thiosemicarbazone derivatives were synthesized via condensation reactions between the corresponding thiosemicarbazides and 4-(methylsulfonyl)acetophenone. The chemical structures of all compounds were elucidated by ...
An acoustic survey in the southeastern Black Sea in the assessment of trachurus mediterraneus (Steindachner, 1868) distribution
(Springer, 2022)
Horse mackerel (Trachurus mediterraneus, Steindachner, 1868) is an important commercial fish distributed along the coast of Turkey. Although, the variety of catching amount of the species fluctuate by years, it is obvious ...
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 ...
Numerical evaluation on the effects of interceptor layout and blade heights for a prismatic planing hull
(Elsevier, 2022)
Planing hulls are exposed to effects such as trim and resistance that have a negative impact on their hydrodynamic performances. Interceptors are one of the systems to find solutions to reduce these negative effects. In ...
