Novel Fe‐Modulating Raney‐Ni Electrodes toward High‐Efficient and Durable AEM Water Electrolyzer

open access: yesAdvanced Energy Materials, EarlyView.
Plasma spray (APS) is used to fabricate Fe‐modulated Raney‐Ni bifunctional electrodes for AEMWE. The resulting NFA‐CA exhibits distinct core–shell NiFe‐NiFe hydroxides, enabling 2 A cm⁻2 at 1.79 V—surpassing the U.S. Department of Energy's target for AWE systems—and demonstrates excellent durability with 1000 hours of stable operation at 1 A cm⁻2 ...

Enhancement of Photocatalytic Activity in BiFeO3 Nanoparticles through Electrical Polarization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study highlights the enhancement of photocatalytic activity in BiFeO3 nanoparticles through electrical polarization (poling). Herein, the proposed mechanism is illustrated, showcasing how poling aligns ferroelectric domains, improves charge separation, and increases the availability of photogenerated carriers.

Mn‐Doped Tuned NiC/NiO Heterostructure for Efficient Electron Transfer in Hydrogen Evolution Reaction

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
In this article, the preparation of a three‐dimensional nanoflower Mn‐ doped NiC/NiO electrocatalyst, which exhibits excellent catalytic activity in the hydrogen evolution reaction. The doping of Mn not only modulates the morphology of the electrocatalyst but also provides electrons to the Ni sites of NiC/NiO, which effect promotes the desorption of H2.

Could the chemical industry mitigate rapid global cooling from a catastrophic volcanic eruption?

open access: yesAIChE Journal, EarlyView.
Abstract Estimates based on historical data place the probability of a catastrophic volcanic eruption in the next 100 years at around one in six. Large volcanic eruptions can lead to significant global cooling for 2–4 years, with potentially devastating impacts on global agriculture.
