P2-type NaNiMnO (NNMO) as cathode material for sodium-ion batteries (SIBs) largely suffers from continuous accumulation of local stress caused by destructive structural evolution and irreversible oxygen loss upon cycling, leading to rapid capacity degradation. Herein, a strategy of negative enthalpy doping (NED), wherein transition metal (TM) sites are substituted with 0.01 mol each Sn, Sb, Cu, Ti, Mg, and Zn to increase the stability of the TM layers, is proposed.

This study aimed to investigate the structural, optical, and electronic properties of WO thin films modified by Ta-doping, considering their potential application in photoelectrochemical (PEC) water splitting. Due to its unique physical and chemical properties, WO films have been commonly suggested as a promising photoanode for hydrogen production. However, the wide bandgap and unsuitable band edge positions of WO limit its PEC efficiency.

The microenvironment regulation of Fe-N single atom catalysts (SACs) critically governs peroxymonosulfate (PMS) activation. Although conventional heteroatom substitution in primary coordination enhances activity, it disrupts Fe-N symmetry and compromises stability. Herein, we propose oxygen doping in the secondary coordination shell to construct Fe-N-CO SAC, which amplifies the localized electric field while preserving the pristine coordination symmetry, thus trading off its activity and stability.

Room temperature superconductivity has become the tireless pursuit of scientists due to its epoch-making significance. Inspired by the recently predicted high superconductivity in LiPH, we identify a new superconductor MgPH by substituting Li with Mg and prove its stability. The superconducting critical temperature ( ) and electron-phonon coupling (EPC) parameters () of MgPH under 280 GPa are predicted to be ∼166 K and ∼1.

The exceptional capacity of lithium-rich manganese-based oxides (LRMO) primarily originates from the reversible oxygen redox process. Nevertheless, long-term cycling inevitably induces lattice oxygen instability, which remains a critical challenge for the practical application of LRMO. Doping with the oxygen-affinity element silicon (Si) has been identified as a promising strategy for stabilizing lattice oxygen due to the strong Si-O covalent bonds and small ionic radii.
