Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, Volume 38, Issue 51, 11 September 2026.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes
Advanced Optical Materials, Volume 14, Issue 33, 4 September 2026.Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.

Advanced Theory and Simulations, Volume 9, Issue 9, September 2026.X2BH6 (X = Li, Na, and K) double perovskite hydrides are investigated using Density Functional Theory (DFT). Highest gravimetric hydrogen storage capacity is found as 19.71 wt % for Li2BH6 and the suitable desorption temperature is found as 308.00 K for K2BH6.

Coupled Dynamics Between Networks and Fields in Physical Space: A Theoretical Perspective
Annalen der Physik, Volume 538, Issue 9, September 2026.Networks embedded in physical space often communicate through dynamical fields that both mediate and respond to collective behavior. A unified theoretical perspective is presented for these network‐field systems, linking established mathematical frameworks and revealing how feedback between discrete interactions and continuous spatial processes can ...

Advanced Physics Research, Volume 5, Issue 9, September 2026.The top panel shows the electronic band structure, which illustrates how the electronic energy varies with momentum along different high‐symmetry directions within the first Brillouin zone. Band structure determines the electronic character of a crystalline solid.

Energy Science &Engineering, Volume 14, Issue 9, Page 4316-4332, September 2026.This study presents an inter‐material transfer learning framework for nanofluid heat transfer prediction in energy systems. By leveraging knowledge from Al2O3‐water data, the model accurately predicts hybrid Al2O3‐TiO2 nanofluid performance with only 20 simulations, achieving R2 = 0.985 and reducing computational requirements by 78.
