Design, synthesis, and theoretical analysis of anthracene-based sensitizers for enhanced dye-sensitized solar cell efficiency Open
In this theoretical study, we systematically designed and analyzed a series of anthracene-based donor–π–acceptor (D-π-A) sensitizers for dye-sensitized solar cells (DSSCs) using Density Functional Theory (DFT). Four dyes ( Mn-1 to Mn-4 ) f…

Condensed Fukui function and experimental evaluation of the corrosion inhibition properties of some antipyrinyl‐imidazotriazole and their derivatives for copper in an acidic environment Open
The effectiveness of synthesized antipyrinyl‐imidazotriazole and its derivatives as inhibitors for the corrosion of copper alloy in 0.5 M H 2 SO 4 solution was tested using weight loss, electrochemical impedance spectroscopy (EIS) and pote…

Synthesis and antitumor activity of some new pyrazolo[3,4-d]pyrimidine and pyrazolo[3,4-b]pyridine derivatives Open
A new series of pyrazolo[3,4-d]pyrimidine-3-carbonitrile and pyrazolo[3,4-b]pyridine-3-carbonitrile derivatives was synthesized by the reaction of 5-amino-1-tosyl-1H-pyrazole-3,4-dicarbonitrile as a key starting material with various elect…
