Summary: A novel green synthesis method using miracle leaf extracts as reducing agent was successfully developed for the preparation of reduced graphene oxide (m-rGO) nanosheets. The m-rGO and chemically prepared GO were characterized using various techniques, confirming the reduction process and structural properties. The m-rGO showed higher sensitivity to methanol vapor compared to GO, making it a promising material for gas sensing applications.

Summary: Nucleate pool boiling of hydrazine-reduced graphene oxide (H-rGO) with rough surface is experimentally investigated. Using the created nucleate boiling setup, heat transfer coefficient (HTC) of nanofluids is investigated with rough surface. The study shows that HTC of nanofluids increases with concentrations and is influenced by surface modification and formation of pores due to nanodeposits.

Summary: Reduced graphene oxide (rGO)-reinforced Al2O3 composites were fabricated by spark plasma sintering, and the effect of graphene oxide (GO) dimensions on the microstructure and mechanical properties of the composites was studied. Thin GO resulted in grain size refinement and grain boundary pinning effects, leading to higher hardness of the composites.

Summary: This study investigated the effects of graphene oxide (GO) and reduced graphene oxide (rGO) on zebrafish hepatocytes using in vitro assays. The results showed that the internalization of GO increased with increasing concentrations, while rGO had stronger interaction with the cell membrane due to its hydrophobic characteristic. After 72 hours of exposure, both GO and rGO showed harmful effects on the cells, but with different mechanisms of toxicity.

Summary: The protection of carbonyl functional groups via dithioacetalization is important for multi-step organic syntheses and has been highly valued in academic and industrial research. Numerous strategies have been developed for the dithioacetalization of carbonyl compounds to synthesize industrially valuable organosulfur compounds. However, greener approaches are now being pursued due to environmental and health concerns. This review highlights recent advances in greener and convenient synthetic approaches for dithioacetalization of carbonyl compounds.

Summary: Chiral transition metal complexes with privileged ligands are efficient catalysts for various asymmetric organic transformations. Transition metal complexes of C1-symmetric pyrrolidine-based ligands have been widely used in asymmetric organic reactions. However, a comprehensive review article on the transition metal complexes of chiral C1-symmetric pyrrolidine-based ligands derived from (L)-proline has not been published.
