Amorphous BiSnxOy for Efficient CO2 Electroreduction to Formate via In Situ Doping

Advanced Science, EarlyView.
The amorphous BiSnxOy catalyst is electroreduced to Sn‐doped Bi during the electrochemical process. The Sn‐modulated Bi exhibits a favorable intermediate adsorption potential, leading to optimal catalytic efficiency. Remarkably, this catalyst demonstrates exceptional performance, achieving a Faradaic efficiency (FEformate) of 95.6% at 800 mA cm−2 in a ...

Orbital Hybridization‐Mediated Decoupling of Electrocatalytic Functions for Paired CO2 Electrosynthesis

Advanced Science, EarlyView.
This study constructs a dual‐scale Ag‐based catalyst on CeO2 nanorods via a facet‐guided strategy. This catalyst can induce a cascaded orbital hybridization effect, which synergistically optimizes oxygen vacancy stability, CO desorption kinetics, and charge transfer efficiency.

Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

Advanced Electronic Materials, EarlyView.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.

Relational Observables in Gravity: a Review

Symmetry, Integrability and Geometry: Methods and Applications, 2012
We present an overview on relational observables in gravity mainly from a loop quantum gravity perspective. The gauge group of general relativity is the diffeomorphism group of the underlying manifold.

Pressure Effects on Monolayer FeCl2: Above‐Room‐Temperature Ferromagnetism with In‐Plane Electric Polarization and Interface‐Free Magnetic Tunnel Junctions

Advanced Electronic Materials, EarlyView.
We investigate the influence of hydrostatic pressure on the physical properties of monolayer FeCl2${\rm FeCl}_2$ for spintronics applications. A phase transition from a ferromagnetic half‐metal to a ferromagnetic semiconductor is unveiled at 4.6 GPa, accompanied by a transition from a non‐polar (1T) to a polar (1H) structure.

MIM‐Diode‐Like Rectification in Lateral 1T/1H/1T‐MoS2 Homojunctions via Interfacial Dipole Engineering

Advanced Electronic Materials, EarlyView.
The metallic 1T and semiconducting 1H phases of MoS2 enable phase‐engineered 1T/1H/1T homojunctions that exhibit MIM‐diode‐like rectification without dissimilar electrodes. Asymmetric 1T/1H interfaces induce interface dipoles and a built‐in potential drop across the 1H barrier, creating a trapezoidal tunnel barrier at zero bias and yielding diode‐like ...
