An Efficient Symmetric Attention Graph Neural Network Model

工程科学与技术
图神经网络（GNNs）已成为处理图结构数据的重要方法，同时，注意力作为图神经网络的流行机制，在各种图优化任务中取得了较好的结果。然而，静态注意力（SA）和动态注意力（DA）具有较高计算复杂度和数据复杂度的问题。因此，本文提出一种融入对称注意力（SDA）的鲁棒图神经网络模型（GSDAT）。首先，提出一个无需学习参数的对称注意力机制，该机制利用特征空间的几何关系来计算目标节点与邻居节点之间的注意力系数，从而计算邻居节点的贡献度。其次 ...

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Amphiphilic Non‐Isocyanate Polyurethane Coatings With Tunable Antifouling and Fouling‐Release Performance: A Log‐Ratio Assessment Framework

Advanced Materials Interfaces, EarlyView.
Amphiphilic non‐isocyanate polyurethane (NIPU) coatings containing reactive hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic methoxy poly(ethylene glycol) (MPEG) prepolymers for marine antifouling (AF) and fouling‐release (FR) applications were investigated. The coatings were evaluated with a set of representative marine foulants.

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications

Advanced Materials Technologies, EarlyView.
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.
