A one-pot electrochemical nickel-catalyzed decarboxylative sp-sp cross-coupling reaction has been developed using redox-active esters prepared in situ from alkyl carboxylates and N-hydroxyphthalimide tetramethyluronium hexafluorophosphate (PITU). This undivided cell one-pot method enables C-C bond formation using inexpensive, benchtop-stable reagents with isolated yields up to 95% with good functional group tolerance, which includes nitrile, ketone, ester, alkene and selectivity over other aromatic halogens.

Amphiphilic copolymers of comb-like poly(poly(ethylene glycol) methacrylate) (PPEGMA) with methyl methacrylate (MMA) synthesized by one-pot atom transfer radical polymerization were mixed with lithium bis (trifluoromethanesulfonyl) imide salt to formulate dry solid polymer electrolytes (DSPE) for semisolid-state Li-ion battery applications. The PEO-type side chain length (EO monomer's number) in the PEGMA macromonomer units was varied, and its influence on the mechanical and electrochemical characteristics was investigated. It was found that the copolymers, due to the presence of PMMA segments, possess viscoelastic behavior and less change in mechanical properties than a PEO homopolymer with 100 kDa molecular weight in the investigated temperature range.

Whether the catalyst can realize the non-CO pathway is the key to greatly improve the catalytic activity and stability of methanol oxidation reaction (MOR). It is feasible to optimize the reaction path selectivity by modifying organic ligands and constructing single-atom systems. At the same time, heterogeneous metal nanosheets with atomic thickness have been shown to significantly enhance the catalytic activity of materials due to their ultra-high exposure of active sites and synergistic effects.

A one-pot hydrothermal reaction was proposed to synthesize Cu-doped BiOCO. Doping Cu with smaller electronegativity than that of Bi and electrochemical reconstruction on BiOCO optimize the hybridization between Bi 6p of BiOCO and O 2p of *OCHO, acquiring FE of ∼100% at a current density of >100 mA cm over a wide pH range.

Article Synopsis
- Tibial fractures are common injuries and require careful monitoring for proper healing, with Osteoprotegerin (OPG) being a crucial marker for this process.
- A new, highly sensitive electrochemical immunosensor has been developed using a nanocomposite material that enhances detection of OPG in serum, addressing existing methods' limitations in sensitivity and specificity.
- This immunosensor shows excellent performance in terms of specificity and stability and is validated for clinical use, effectively aiding in the assessment of fracture healing and the evaluation of orthopedic drug efficacy in real patient samples.
