Protonation has been considered essential for the pseudocapacitive energy storage of polyaniline (PANI) for years, as proton doping in PANI chains not only activates electron transport pathways, but also promotes the proceeding of redox reactions. Rarely has the ability for PANI of storing energy without protonation been investigated, and it remains uncertain whether PANI has pseudocapacitive charge...
Reprogramming the immunologically “cold” environment of solid tumors is currently becoming the mainstream strategy to elicit powerful and systemic anticancer immunity. Here, a facile and biomimetic nano‐immunnoactivator (CuS/Z@M4T1) is detailed by engineering a Zn2+‐bonded zeolitic imidazolate framework‐8 (ZIF‐8) with CuS nanodots (NDs) and cancer cell membrane for amplified near‐infrared‐II (NIR‐II)...
Fabrication of transition‐metal catalytic materials is regarded as a promising strategy for developing high‐performance sodium–selenium (Na–Se) batteries. However, more systematic explorations are further demanded to find out how their bonding interactions and electronic structures can affect the Na storage process. This study finds that lattice‐distorted nickel (Ni) structure can form different bonding...
