Fabrication and Performance of Durable Superhydrophobic Cement Mortar by Combining Dry Modification with Stearic Acid and Template Molding

Cement mortar is widely used in buildings, roads, bridges, and other infrastructure. However, its inherent porous structure and hydrophilicity facilitate the penetration of water and aggressive media into the cement mortar matrix, accelerating rebar corrosion and compromising str...

Practical reliability-aware temporal state correction for depth-assisted RGB-skeleton action recognition

RGB-D action recognition benefits from skeleton motion, RGB appearance, and depth geometry, yet auxiliary modalities are not equally helpful for every sample. We present a reliability-aware temporal state correction method that treats the skeleton representation as the primary te...

Construction of a 0D/2D S-Scheme Heterojunction Based on Ni-Doped CsPbBr3 and ZnO for Enhanced Photocatalytic CO2 Reduction

Abstract Doping with transition metals and constructing S-scheme heterojunctions are well-recognized strategies for boosting photocatalytic CO2 reduction. Herein, we adopt a cascade design approach to fabricate a Ni-doped CsPbBr3/ZnO S-scheme heterojunction, aiming to further imp...

N -Shaped vs Λ-Shaped Bridging Symmetric Molecules: Geometric Compatibility Drives Performance Improvement in Perovskite Solar Cells

Abstract Intrinsic defects limit the further improvement of photovoltaic performance and stability of perovskite solar cells (PSCs). Bridging symmetric molecules have been proved to be a kind of promising additive for passivating defects within perovskites. However, there is curr...

Research on the Game Dynamics of Optional Public Goods

The public goods game (PGG) serves as a powerful framework for investigating human cooperative behavior. While prevailing theories emphasize imitation as the primary driver of strategy updating, evidence from an empirical study on voluntary spatial PGG revealed that human decisio...

Harmonizing A‑Site Cation Incorporation With Conductive Grain‑Boundary Bridging for Durable Perovskite Solar Cells

ABSTRACT While perovskite solar cells (PSCs) have achieved significant progress in power conversion efficiency ( PCE ), their commercialization remains hindered by a critical challenge: irreversible efficiency degradation during device operation, primarily caused by the spontaneo...

A Stacking-Fusion Feature Selection Framework for Cross-Year and Cross-Cultivar Leaf Hyperspectral Rice Yield Estimation

Single-criterion feature selection for hyperspectral crop yield estimation suffers from methodological bias and limited generalisation. This study proposes a stacking-fusion feature selection framework with a ridge-regression meta-learner (STACKING_FUSION) that transfers the stac...

Dual-Mode Responsive Dynamic Afterglow Color in CarbonDots and Carbon Nitride Composite for Advanced Optical Informationand Temperature Sensors

Abstract Responsive dynamic afterglow carbon dot (CD) materials, which can continuously emit light of dynamically varying color after excitation cessation, promise broad applications in advanced information encryption and related fields. However, as most reported CD-based aftergl...
