Summary: It is fascinating to use nickel based neutral P<^>O type catalysts to prepare polyethylene with ultra-high molecular weight under homogeneous conditions. This contribution explores the ligand remote electronic effect in sterically hindered phosphine-phenolate based neutral nickel catalysts Ni1-Ni3 to produce UHMWPE. The maximal activity of these catalysts was found to be 1.33 x 106 g mol-1 h-1, indicating their high reactivity. The nickel catalysts show good thermal stability at a high temperature of 120 degrees C. Moreover, all these catalysts are capable of generating UHMWPE with a maximum Mn of 2.51 x 106 g mol-1 by Ni2, which is attributed to the effective shield provided by the minimum distance between the Ni center and the oxygen atom in Ni1 and the steric remote substituents effect.

Summary: Ring-opening copolymerization reactions of epoxides, carbon dioxide and cyclic esters using bimetallic chloride indium complexes as catalysts were conducted under mild reaction conditions. The catalysts exhibited high catalytic activity and selectivity in the absence of a co-catalyst, leading to the formation of poly(cyclohexene carbonate) (PCHC). Furthermore, polyester-polycarbonate copolymers poly(lactide-co-cyclohexene carbonate) (PLA-co-PCHC) were synthesized via a one-pot one-step route without the use of a co-catalyst. The copolymers showed different thermal properties by adjusting the CO2 pressure and monomer feed.

Summary: Osteosarcoma is a highly invasive and deadly cancer that often occurs in children and adolescents. The overexpression of PLK1 gene in tumors promotes cancer cell proliferation and transformation, making it a therapeutic target for osteosarcoma. However, current RNA interference-based therapies lack a safe and efficient nonviral gene vector. In this study, biodegradable and CO2-derivative cationic poly(vinylcyclohexene carbonates) (CPCHCs) were used as gene vectors for siPLK1 therapeutic strategy in osteosarcoma treatment. Among them, CPCHC60 showed excellent performance in gene transfection efficiency, endo-lysosome escaping, biodegradability, and biosafety. The treatment with CPCHCs/siRNA nanoparticles significantly down-regulated the expression level of PLK1 gene in osteosarcoma cells, leading to cell arrest and apoptosis, resulting in significant tumor regression both in vitro and in vivo. This study provides new insights into the development of superior nonviral gene vectors for cancer treatment and holds high potential for translational nanomedicine applications.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
