Advanced Functional Materials, EarlyView.Electrochemical CO2 reduction (ECR) to formate is a promising route for sustainable chemical production. Herein, we report the synthesis catalysed byBi‐HfO2@C. The AIMD simulations, DFT calculations, and in situ SEIRAS measurements show that the modification of HfO2 on the Bi surface steers the interfacial water to adopt a favorable hydrogen‐down (OH2↓)

Crystal Growth Engineering for Dendrite‐Free Zinc Metal Plating
Advanced Materials, EarlyView.This research employed the rare‐earth ion dysprosium (Dy) to modulate aqueous zinc (Zn) metal plating. Integrated multiscale experiments and computational modeling unveiled the preferential adsorption of Dy on specific crystal facets, which activated screw dislocation‐driven Zn growth.

Asymmetry of the Ferroelectric Phase Transition in BaTiO3
Advanced Materials, EarlyView.Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Qing history in America: past accomplishments and present trends [PDF]
, 1984 Fifty years ago, Chinese history hardly existed as a field of study in the United States. In 1935, there were no more than a dozen active American sinologists of whom only one or two were historians.1 Today there are over sixteen hundred members of ...

Space Group Modulated Upconversion and Mechanoluminescence in [YbEu] Cocrystal Complexes
Advanced Optical Materials, EarlyView.We report here a space group regulation strategy to optimize both upconversion and mechanoluminescence in cocrystal assemblies, representing the first example of integrating these two properties within a single lanthanide complex material. ABSTRACT Lanthanide complexes exhibiting stimuli‐responsive luminescence, such as upconversion (UC) and ...

A Crisis of Competence: Information, Corruption, and Knowledge about the Decline of the Qing State
Journal for the History of Knowledge, 2020 This article elaborates on the claim of this special issue that “bureaucratic actions” are “knowledge practices” that have “the power to both make and break social and material worlds” to question the standard assumption that the Qing state became ...

CypD Dependent mPTP Opening Is Crucial for Oxidized Mitochondrial DNA Release in Ferroptosis
Advanced Science, EarlyView.Ferroptosis is driven by mitochondrial permeability transition pore (mPTP) opening, which induces mitochondrial swelling and releases oxidized mitochondrial DNA. The released mtDNA activates cGAS–STING signaling, promotes ferritinophagy, and amplifies ferroptotic cell death. Disruption of mtDNA repair sensitizes tumors to ferroptosis in vivo, revealing
