We introduce the concept of modulation doping in three-dimensional nanostructured bulk materials to increase thermoelectric figure merit. Modulation-doped samples are made two types nanograins (a two-phase composite), where dopants incorporated only into one type. By band engineering, charge carriers could be separated from their parent grains and moved undoped grains, which would result enhanced mobility comparison uniform due a reduction ionized impurity scattering. The electrical...
Abstract Precisely regulating the electronic structures of metal active species is highly desirable for electrocatalysis. However, carbon with inert surface provide weak metal–support interaction, which insufficient to modulate nanoparticles. Herein, we propose a new method control electrocatalytic behavior supported nanoparticles by dispersing single atoms on an O‐doped graphene. Ideal atomic are firstly computationally screened. We then verify this concept deposition Ru onto graphene...
Electrochemical nitrogen reduction reaction (NRR) over nonprecious-metal and single-atom catalysts has received increasing attention as a sustainable strategy to synthesize ammonia. However, the atomic-scale regulation of such active sites for NRR catalysis remains challenging because large distance between them, which significantly weakens their cooperation. Herein, utilization regular surface cavities with unique microenvironment on graphitic carbon nitride "subnano reactors" precisely...
Abstract The resistance of gels and elastomers increases significantly with tensile strain, which reduces conductive stability restricts their use in stable reliable electronics. Here, highly tough hydrogels composed silver nanowires (AgNWs), liquid metal (LM), poly(vinyl alcohol) (PVA) are fabricated. stretch‐induced orientations AgNWs, deformable LM, PVA nanocrystalline create pathways, enhancing the mechanical properties hydrogels, including increased ultimate fracture stress (13‐33 MPa),...
Cohesive and interfacial adhesion energies are difficult to balance obtain reversible adhesives with both high mechanical strength strength, although various methods have been extensively investigated.

Gas sources rich in CO2 derived from biomass/waste gasification, anaerobic digestion, or industrial carbon capture often contain impurities such as H2S, H2O, and NH3, which can significantly hinder catalyst performance. Here, we show the role of NH3 on reverse water-gas shift (RWGS) reaction over a commercial Cu/ZnO/Al2O3 catalyst, examining its effects both catalytic activity structure. We found that reversibly decreases conversion immediately by suppressing carbonate hydrogenation CO...

Abstract Poor interfacial contacts of Li mental/solid‐state electrolytes (SSEs) cause high impedance and induce lithium dendrite growth, which hinders the practical viability solid‐state batteries (SSBs). Optimizing surface chemistry SSEs has been widely adopted for improving Li/SSE contact. Their surface's microstructure, another critical factor influencing actual performance SSBs, however, seldom paid attention to; corresponding mechanism remains unclear. Addressing this issue, authors...

Advancing the high-voltage stability of O3-type layered cathodes for sodium-ion batteries is critical to boost their progress in energy storage applications. However, this type cathode often suffers from intricate phase transition and structural degradation at high voltages (i.e., >4.0 V vs Na+/Na), resulting rapid capacity decay. Here, we present a Li/Ti cosubstitution strategy modify electronic configuration oxygen elements oxide cathode. This deliberate modulation simultaneously mitigates...
