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

open access: yesGeophysical 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 ...

Sulfur Vacancy‐Engineered Co9S8‐Ni3S4 Heterostructure as a Hydrogen Spillover Catalyst for Efficient Alkaline Water Splitting

open access: yesAdvanced Science, EarlyView.
A sulfur vacancy‐engineered Co9S8‐Ni3S4 hollow heterostructure is rationally designed to trigger hydrogen spillover, where vacancy‐mediated interfacial modulation enables efficient H migration and accelerates HER kinetics. Abstract Developing highly efficient and robust catalysts based on earth‐abundant materials for electrochemical water splitting ...

Tailoring Ni–Co–Mn–Sn Ribbons by Ge Doping for Enhanced Magnetocaloric Effect

open access: yesAdvanced Electronic Materials, EarlyView.
Ni42Co8Mn39Sn11‐xGex (x = 1, 2 and 3) ribbons show tunable martensitic transformation and enhanced magnetocaloric performance through Ge substitution. Hysteresis is reduced with improved geometric compatibility between martensitic and austenitic phases, and the x = 2 sample exhibits an optimized magnetization change (ΔM) response, yielding an entropy ...
