Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Reversible Ion Induced Modification of Consequent Secondary Electron Emission in Porous Silicon [PDF]

, 2009
We report measurements of secondary electron emission (SEE) induced by electron and ion bombardment on porous silicon (PS). We found that electron induced emission is strongly reduced by ion bombardment, and that this reduction is reversible.

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.

2D/2D MOF/MXene Schottky Junction: Prolonged Carrier Lifetime and Enhanced Hydrogen Evolution Efficiency

Angewandte Chemie, EarlyView.
This study designs an innovative 2D/2D Schottky heterojunction by integrating a 2D MOF with exfoliated Ti3C2 MXene. The MXene serves as a hole‐accumulation center, effectively enhancing charge carrier separation, prolonging carrier lifetimes, and achieving an impressive hydrogen evolution rate of 5000 µmol gcat−1 under visible‐light irradiation ...
