Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

open access: yesAdvanced Materials, EarlyView.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Gridded Assessment of Mainland China’s Solar Energy Resources Using the Typical Meteorological Year Method and China Meteorological Forcing Dataset

open access: yesAtmosphere
The National Standard of China has recommended the typical meteorological year (TMY) method for assessing solar energy resources. Compared with the widely adopted multi-year averaging (MYA) methods, the TMY method can consider the year-to-year variations

Regional integration and the new type of commercial warfare [PDF]

open access: yes
The lowest the number of the regional integration areas, the higher the propensity for protectionism (Krugman). The revival of regional protectionism measures meets the case of a commercial warfare. In the largest integrated market, investors must “play”

Natural Design of a Stabilized Cross‐β Fold: Structure of the FuA FapC from Pseudomonas Sp. UK4 Reveals a Critical Role for Stacking of Imperfect Repeats

open access: yesAdvanced Materials, EarlyView.
We report a 3.2 Å cryoEM structure of functional amyloid protein FapC from Pseudomonas sp. UK4, an essential component of bacterial biofilm, which reveals a Greek key‐shaped protofilament, supports bioinformatically determined motifs, nuances AlphaFold predictions, emphasizes heterogeneous cross‐β stacking in amyloid cross‐seeding and shows strain ...

Triboelectric Nanogenerators Enable Multifunctional Ice Accretion, Melting, and Interfacial Fracture Detection

open access: yesAdvanced Materials, EarlyView.
Water impacting, freezing, melting, and being mechanically removed from the designed dielectric surfaces generates a triboeletric signal that can be used to detect various icing and de‐icing scenarios. The charge transferred directly scales with the interfacial fracture mechanism, further validating triboelectricity as an excellent ice‐detection ...
