Characterization of Polylactic Acid Biocomposites Filled with Native Starch Granules from Tubers.

Biocomposites were fabricated utilizing polylactic acid (PLA) combined with native starch sourced from mountain's yam ( Knuth), an underexplored tuber variety. Different starch compositions (7.5, 15.

Chemical composition, antioxidant activity and toxicity of the essential oil from .

(CM) has been used by the population as a home remedy for inducing sleep, and as a sedative and analgesic. This study presents the first evaluation of the antioxidant activity of the essential oil (EO) obtained through hydrodistillation of the aerial parts of CM. NaCl, CaCl, and Tween 20 were used as additives and the yield, chemical composition, and toxicity of the EO were evaluated.

Effect of Pluronic P103 Concentration on the Simple Synthesis of Ag and Au Nanoparticles and Their Application in Anatase-TiO Decoration for Its Use in Photocatalysis.

Silver and gold nanoparticles were synthesized under environmentally-friendly reaction conditions by using a biodegradable copolymer and water as a solvent. The triblock copolymer Pluronic P103 was utilized as a stabilizing agent or soft template to produce Ag and Au nanoparticles (NPs) of different sizes. Moreover, in the synthesis of Au NPs, the polymer acted as a reducing agent, decreasing the number of reagents used and consequently the residues produced, hence, rendering the procedure less complicated.
