We report a sonochemical method for the fabrication of stable TiO₂–chitosan hybrid microspheres possessing nanoporous structure and antimicrobial properties.

The initial growth of acoustic cavitation activity is important in some applications such as therapeutic and diagnostic medicine. has been investigated using sonoluminescence sonochemical (sonochemiluminescence) at 358 kHz, 647 kHz 1062 5 W, 15 W 30 applied power levels. sonochemically active bubble population found to be much faster than that whereas almost similar rate observed for both populations. This suggests the resonance size ranges bubbles are different they have range kHz. At...

This study investigates the fabrication and performance analysis of Al/CuO:LaB6/p-Si/Al diodes with CuO-doped LaB6 interlayer films varying concentrations (1%, 5%, 10%). Experimental evidence demonstrates limitations 0% CuO doping, as pure lacks a significant barrier height, resulting in ohmic behavior unsuitable for intended applications. Through comprehensive analyses under illuminations (20–100 mW/cm2) frequencies (10 kHz–1 MHz), reveals that controlling doping significantly enhances...

Abstract Complexes of N,N′-bis(salicylidene)-1,3-diaminopropane, an ONNO type ligand, with ZnX2 (X = AcO−, NO3-, Cl−, Br−, I−) salts were prepared. Molecular structures these complexes identified using elemental analyses, IR spectrometry and X-ray diffraction techniques. It has been observed that the reactions between zinc ions said ligand tend to produce polynuclear depending on anion present either di- or trinuclear are formed. Thus, it can be deduced from results presented in this article...
