Summary: The optimized synthesis of gold nanoparticles with different shapes and sizes was achieved using ultrasonic irradiation assisted Turkevich-Frens method. The effects of different ultrasound powers and continuous irradiation time were studied to control the size and shape of the GNPs colloidal solutions. The resulting quasi-spherical GNPs showed sizes ranging from 12 to 16 nm, with different shapes such as pentakis dodecahedron, triakis icosahedron, and tetrakis hexahedron.

Summary: Imidazole-based compounds are a group of heterocyclic compounds with various biological and pharmaceutical activities. Conventional syntheses of these compounds are time-consuming, require harsh conditions, and result in low yields. Sonochemistry has emerged as a promising green technique for organic synthesis, with advantages such as enhanced reaction rates, improved yields, and reduced use of hazardous solvents. Ultrasound-assisted reactions have been increasingly applied in the synthesis of imidazole derivatives, providing greater benefits and a new strategy.

Summary: Ultrasonic irradiation can induce catalytic activity in nanoparticles similar to light-induced photocatalysis. The size and ligand of the nanoparticles affect the efficiency of singlet oxygen generation. Sonosensitization and photosensitization have different mechanisms, and the size effect is more significant in sonosensitization for Au144 NCs.

Summary: The high use of zinc borate additives and their limited solubility in water lead to their persistence and accumulation in biological systems. Soluble forms of boron, on the other hand, are easily taken up by plants. The potential toxicity of zinc borate and its dissociated compounds were evaluated through ecotoxicological tests, showing significant effects on plant growth. Different species showed varying sensitivity to zinc borate, suggesting the need for more complex tests to evaluate additive toxicity in the environment.

Summary: Sonochemical reactors are promising for wastewater treatment, but the influence of air bubbles on sonochemistry needs further investigation. This study found that low concentrations of bubbles can enhance sonochemical activity, while high concentrations tend to decrease it. The effects of different bubble sizes on sonochemical activity were examined, and the dependence on bubble characteristics for inhibiting or enhancing effects was analyzed.

Summary: In this study, amylopectin was degraded using ultrasonication, resulting in a significant decrease in molecular weight with extended processing time. The preferential degradation of larger molecular mass of amylopectin led to the disruption of amylopectin and a narrower molecular size distribution. Break points were observed firstly at B3 chains and then at B2 chains, causing a decrease in branching degree of the samples and making alpha-1,6-glycosidic bonds more likely to break as processing time increased.

Summary: This study investigated the drying characteristics of fish, chicken and beef samples using microwave drying method. Results showed that drying time decreased with increasing microwave power and fish fillets dried faster than chicken and beef samples. Different drying models were tested, with logarithmic and Midilli et al. models found to be most appropriate in describing the drying behavior. Effective moisture diffusion coefficients and activation energies were computed for all meat samples. The highest and lowest energy consumptions were found in chicken and fish drying processes, respectively, and the microwave power levels were identified as the main factors affecting color change during drying.
