Synthesis, Identification, and Evaluation of Antibacterial Activity of Some New 4,5-Dihydro-1H-Pyrazoles, Derivatives from Substituted Chalcones

In this work, a series of new 4,5-dihydro-1H-pyrazole derivatives (M21-M25) has been synthesized successfully via the reaction of different aldehydes with ketones to produce chalcones, followed by the reaction with hydrazine and phenyl hydrazine. The prepared compounds were identified using FT-IR spectroscopy, 1H NMR spectroscopy, and 13C NMR spectroscopy.

Antibacterial Matte Glass-Ceramic Coatings with Satin Texture for Ceramic Tiles

Antibacterial satin glass-ceramic coatings for ceramic tiles have been developed by one-stage firing on the basis of high-calcium zinc aluminum silicate frits, which are modified with heavy metal cations. The antibacterial effect of the developed matte glass-ceramic coatings with a satin texture was established due to the effect of potentiating the antibacterial activity of the combined action of the hardystonite crystalline phase and fillers of zinc and tin oxides.
