An up-to-date crustal deformation map of Iran using integrated campaign-mode and permanent GPS velocities

Geophysical Journal International, 2019
We present the most extensive and up-to-date unified GPS velocity field for Iran. We processed the data collected during 10 yr (2006–2015) from the Iranian Permanent GNSS Network (IPGN) and combined them with previously published velocity solutions from ...

Optimal Chirality Enhances Long‐Range Fluctuation‐Induced Interactions in Active Fluids

Advanced Science, EarlyView.
Chiral active particles move along curved trajectories arising from the interplay of propulsion and self‐rotation. How chirality influences fluctuation‐induced forces in active matter systems remains unclear. It is shown that particle shape dictates this effect: chirality suppresses forces for circular particles but can enhance them for elongated ones,

Spatially Separated Molecular Activation Over Dual Sites in Sn‐Doped ZnGa2O4/SnO2 Photocatalysts Toward Complete VOCs Mineralization

Advanced Science, EarlyView.
The graphical abstract illustrates the photocatalytic mechanism of Sn‐doped ZnGa2O4 with in situ loaded SnO2 (SZGO), highlighting directional electron migration and selective adsorption/activation. ZnGa2O4 domains facilitate H2O activation to generate ·OH radicals, while SnO2 domains enriched with electrons promote O2 activation to form ·O2− and 1O2 ...
