Ultra-narrow Negative Flare Front Observed in Helium-10830~\AA\ using the 1.6 m New Solar Telescope

open access: yes, 2016
Solar flares are sudden flashes of brightness on the Sun and are often associated with coronal mass ejections and solar energetic particles which have adverse effects in the near Earth environment.

Nature‐Inspired Sustainable Cooling for Photovoltaics with Enhanced Temperature‐Salinity Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
Addressing solar panel overheating, a nature‐inspired cooling system mimicking ocean currents is developed. A moisture‐absorbing solution layer uses sunlight, radiative cooling, and moisture processes to create temperature/salinity gradients, accelerating circulation. The prototype cools panels by up to 18.2 °C under sunlight, sustains cooling, rapidly

Ion‐Selective Microporous Membranes via One‐Step Copolymerization Enable High‐Performance Redox Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step copolymerization strategy is developed to produce low‐cost microporous ion exchange membranes that boost both the efficiency and lifespan of flow batteries. When combined with organic electrolytes in aqueous systems, these membranes enable safe and cheap flow battery energy storage, supporting the widespread integration of renewable

Lateral intracerebroventricular injection of Apelin-13 inhibits apoptosis after cerebral ischemia/reperfusion injury

open access: yesNeural Regeneration Research, 2015
Apelin-13 inhibits neuronal apoptosis caused by hydrogen peroxide, yet apoptosis following cerebral ischemia-reperfusion injury has rarely been studied. In this study, Apelin-13 (0.1 µg/g) was injected into the lateral ventricle of middle cerebral artery

Tailoring Redox Active Sites with Dual‐Interfacial Electric Fields for Concurrent Photocatalytic Biomass Valorization and H2 Production

open access: yesAdvanced Functional Materials, EarlyView.
A rationally engineered bifunctional photocatalyst is reported, which achieves simultaneous selective oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐diformylfuran (DFF) and efficient H2 evolution. By precisely positioning Au and Co3O4 on Zn3In2S6 nanosheet, dual interfacial electric fields are well constructed to spatially separate ...

CX3 chemokine receptor 1 defciency leads to reduced dendritic complexity and delayed maturation of newborn neurons in the adult mouse hippocampus

open access: yesNeural Regeneration Research, 2015
Previous studies have shown that microglia impact the proliferation and differentiation of neurons during hippocampal neurogenesis via the fractalkine/CX3 chemokine receptor 1 (CX3CR1) signaling pathway.

Waiting time distribution of solar energetic particle events modeled with a non-stationary Poisson process

open access: yes, 2014
We present a study of the waiting time distributions (WTDs) of solar energetic particle (SEP) events observed with the spacecraft $WIND$ and $GOES$. Both the WTDs of solar electron events (SEEs) and solar proton events (SPEs) display a power-law tail ...

Microfluidic Synthesis of Channel‐Rich Pd‐Cu Alloy Nanodendrites for Efficient Electrocatalytic CO2 Reduction to Formate

open access: yesAdvanced Functional Materials, EarlyView.
A microfluidic system enables the rapid, room‐temperature fabrication of channel‐rich Pd‐Cu alloy nanodendrites with tunable composition, uniform morphology, and finely branched internal structures. The resulting catalysts exhibit over 90% formate selectivity across a broad potential window, along with excellent CO tolerance and enhanced long‐term ...
