Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

open access: yesAdvanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

Breaking the Capacity Limit for WO3 Anode‐Based Li‐Ion Batteries Using Photo‐Assisted Charging

open access: yesAdvanced Functional Materials, EarlyView.
This image illustrates a photo‐assisted rechargeable lithium‐ion battery. (a) shows the battery structure, where light enhances electron‐hole generation in the anode, boosting ion flow. (b) compares discharging performance, revealing over 60% higher capacity under light compared to dark conditions, showcasing the benefit of light‐assisted energy ...

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Polarized equatorial emission and hot spots around black holes with a dark matter halo

open access: yesEuropean Physical Journal C: Particles and Fields
We study linear polarization of the accretion disks around black holes with a dark matter halo. The interaction of the black hole with the dark matter is modeled by considering an exact solution to the Einstein equations which describe a superposition of
