Design Rules for Quantitative Control of Intragrain Planar Defects in Halide Perovskites

open access: yesAdvanced Science, EarlyView.
Dose‐budgeted electron microscopy reveals the design rules governing intragrain planar defects in halide perovskites: {112}t ferroelastic twins proliferate with increasing tetragonality and grain size, whereas {111}c twins and stacking faults emerge as the lattice approaches cubic symmetry.

Effective Solvent‐Engineered All‐Inorganic CsPbI2Br Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
All‐inorganic CsPbI2Br perovskite composition has gathered a lot of attention in recent years due to its thermal robustness, convenience for space applications as well as for the all‐perovskite triple junction applications as a top cell due to its wide‐bandgap (1.9 eV) nature.

A Composite Sb-doped SnO2 Electrode Based on the TiO2 Nanotubes Prepared by Hydrothermal Synthesis

open access: yesInternational Journal of Electrochemical Science, 2011
A hydrothermal synthesis approach was adopted to embed Sb-doped SnO2 into TiO2 nanotubes to form a three dimensional electrode(TiO2-NTs/SnO2-Sb), and it was compared with the conventionally fabricated Ti/SnO2-Sb2O5 electrode(Sb-doped SnO2 coated Ti sheet)

MXene‐Based Room‐Temperature NO2 Gas Sensors: A Meta‐Analysis

open access: yesAdvanced Science, EarlyView.
This study presents the first comprehensive meta‐analysis of MXene‐based NO2 sensors, decoding 32 study characteristics across 61 peer‐reviewed studies. By isolating materials chemistry as the primary performance driver over device‐level parameters, the authors establish a methodological blueprint and a predictive structure–function map to accelerate ...

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

open access: yesAdvanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.
