Some semicarbazide derivatives and their antimicrobial activity
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1993 Various semicarbazides and thiosemicarbazides (1-5) and their cyclised products, triazoles, oxadiazoles and thiadiazoles (6-9) have been reported to possess antibacterial, antitubercular and antifungal activities. Based on these findings it w as of interest to prepare some new arylsemicarbazide and arylthiosemicarbazide derivatives and to evaluate ...

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.High‐consistency silicone rubbers can be foamed with various chemical and physical blowing agents. However, due to the toxic and, therewith, harmful effects of chemical blowing agents, physical blowing agents are becoming increasingly important. In this thesis, the influence of the viscosity adjusted via the silica content of different high‐consistency

SusMat, Volume 5, Issue 6, December 2025.This review summarizes advances in tin (Sn)‐based perovskite solar cells, a promising lead‐free alternative. It examines the main causes of Voc and fill factor losses, including Sn2+ oxidation, undercoordinated sites, and deep‐level traps. Strategies such as molecular coordination, surface passivation, compositional tuning, interface engineering, and ...

Improvement Upon a Largely Forgotten Method for the Synthesis of N-Alkyl Urazoles
ReactionsN-Alkyl urazoles are important heterocyclic compounds that serve as important precursors to potent N-alkyl 1,2,4-triazoline-3,5-dione electrophiles. Traditional methods for urazole synthesis rely upon the use of toxic isocyanates.

Convulsant Effects of Semicarbazide in Epileptic Monkeys.
Experimental Biology and Medicine, 1956 Summary(1) Threshold convulsant dosages to rapid intravenous injection of semicarbazide were significantly lower in chronically epileptic monkeys than in normal unoperated controls. (2) Clinical seizures following intravenous injection of threshold convulsant doses of semicarbazide occurred after a latent period of 2 to 3 1/2 hours. With suprathreshold
