Advanced Science, EarlyView.A type of thermoelectric ionogels with convertible n‐p thermopowers are demonstrated with Seebeck coefficients ranging from ‐3.61 to +9.74 mV K−1. Thus, thermoelectric gating organic electrochemical transistor is achieved by employing ionogel as thermoelectric modules and ionic dielectrics simultaneously, paving the road to self‐powered, highly ...

Advanced Science, EarlyView.A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Advanced Science, EarlyView.A novel synergistic strategy by employing dual functional sulfur‐containing additives of lithium sulfide (Li2S) and its oxidation product lithium sulfate (Li2SO4) was proposed. Li2SO4 absorbs the solvent molecules to direct the formation of a uniform, Li2O‐rich, and adaptive interphase, which accommodates volume expansion and suppresses parasitic ...
