The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

A “two‐in‐one” photoreduction strategy enabled by electron‐rich yolk Cd species both remote from and adjacent to sulfur vacancies is delivered to be ultraselective for the reduction of O2 and •CO2− in situ formed on the shell Bi2S3 composition (hole) by water oxidation and oxidative C–C cleavage of various biomass organic acids, furnishing CO with > 99%

A compact, nonporous, and highly crystalline layered inorganic precursor formed by thermal evaporation inherently restricts its conversion into the halide perovskite phase during vapor‐assisted hybrid two‐step deposition. Introducing localized heterogeneous nucleation sites during vapor deposition enables deliberate modulation of the inorganic layer's ...

A synergistic interface regulation strategy using high‐dielectric BaTiO3 and sulfate‐derived S─O bonds is developed to unlock high‐voltage LiNi0.5Mn1.5O4 all‐solid‐state batteries. By mitigating space‐charge layer effects and stabilizing lattice oxygen, the system achieves high‐rate (3 C) and durable operation in 5 V‐class cobalt‐free solid‐state ...

Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

Molecular dynamics simulations with machine learning potentials, combined with experiments, reveal how interlayer metals govern Li alloying and crystallization in zero‐excess lithium batteries. Mg and Zn promote solid‐solution alloy‐mediated pathways that influence Li diffusion and structural uniformity, while Bi forms ordered intermetallics with more ...

We identify two decisive levers for SAM interfaces: molecular design (carboxylic acid‐based, phosphonic acid, other anchoring chemistries, and polymeric SAMs) and mixing routes (co‐assembly, in situ assembly, pre‐ and post‐treatment). Coordinated tuning of headgroups and assembly pathways optimises energy alignment and film formation, suppresses ...
