Herein, various synthesis techniques, properties, applications of these materials have been discussed. The detailed discussion properties with experimental parameters has carried out. characterization techniques for nanostructure also Their physical chemical addressed. future aspects such nanostructures biomedical other discussed a special emphasis on their properties.
In this study, we introduce a single/few-layered graphene oxide (GO) synthesized with ultrasonication, and demonstrate its high dielectric permittivity in the frequency range of 20 Hz to 2 MHz temperature 30 °C 180 °C.
In this work, mesoporous (pore size below 4 nm) composite nanoparticles of ZnO-Ag2O/Ag, ZnO-CuO, and ZnO-SnO2 d ≤ 10 nm (dia.) have been synthesized through the in situ solvochemical reduction method using NaBH4. These exhibited excellent killing efficacy against Gram-positive/negative bacterial fungal strains even at a very low dose 0.010 μg/mL. Additionally, by applying silico docking approach, microorganism-specific targeted proteins their interactions identified to explain best...
In this work, we synthesized chiral mesoporous silica (CMS) spheres, which can be used as a potential candidate for separation. The CMS spheres with controllable pore sizes (of 2−3 nm) and high surface areas of ca. 614 m2 g−1 were by templating block copolymers based on poly(ethylene oxide) dl-glutamic acid [PEO113-b-(GluA)10]. ordered structure the mesopores was characterized high-resolution transmission electron microscopy, average diameters estimated from nitrogen adsorption−desorption...
