Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation

Advanced Science, EarlyView.
Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical

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.

Chemical Information From the Ehrenfest Force Field Based on Reduced Density Matrix Functional Theory

Journal of Computational Chemistry, Volume 47, Issue 5, 15 February 2026.
Reduced Density Matrix Functional Theory is evaluated as a practical route to approximate the exchange‐correlation contribution to the Ehrenfest force field. Across molecules from diatomics to polyatomics, it reproduces key bonding features and force‐field topologies while exposing limits in strongly correlated cases, enabling EhF analysis in larger ...

Proton transfer from 1,4-pentadiene to superoxide radical anion: a QTAIM analysis

Revista Colombiana de Química, 2014
We studied the bis-allylic proton transferreaction from 1,4-pentadiene to superoxideradical anion (O2·־). Minima andtransition state geometries, as well asthermochemical parameters were computedat the B3LYP/6-311+G(3df,2p)level of theory.
