High-speed Video Observations on Abrupt Elongations of the Positive End of Bidirectional Leader

open access: yes应用气象学报, 2020
One of the most important advances in lightning physics research in recent decades is the introduction of the the bidirectional developmengt of leaders and its observation and verification, but this theory is not paid much attention until more and more ...

Metal‐Organic Frameworks Facilitating Complexation for Long‐Cycle Zinc‐Bromine Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The organic ligands (imidazole and benzimidazole) from the decomposed zinc ZIF‐62 is proposed to further improve the Br2 complexing ability of the mature complexing agent (i.e., N‐methyl‐N‐ethyl pyrrolidinium bromide (MEP) ionic liquid). The synergistic effect between Im/BIm of the decomposed ZIF‐62 toward bromine species and MEP toward bromine species,

Two-dimensional Optical Observation of Striking Distance of Lightning Flashes to Two Buildings in Guangzhou

open access: yes应用气象学报, 2020
Lightning can strike directly on buildings, lightning protection devices or the lateral surface of buildings, endangering buildings on the ground. Effective lightning protection measures can avoid lightning damage to buildings and prevent possible fire ...

Biomimetic, Suturable, and Extensible Electrospun Scaffolds for Lower Urinary Tract Surgical Reconstruction

open access: yesAdvanced Healthcare Materials, EarlyView.
Biomimetic, suturable, biodegradable fibrous scaffolds are engineered to mimic the tensile properties of LUT tissue using photocrosslinked 5:5% weight per volume elastin‐like peptide and methacrylated gelatin (5E5G). In vitro, urothelium, smooth muscle, and fibroblast 7 day cytocompatibility is demonstrated.

Reversible Phase Transitions of Anionic and Cationic Surfactant Mixtures Drive Shape Morphing Droplets

open access: yesAdvanced Materials, EarlyView.
A light‐controlled, reversible phase transition of ionic surfactant assemblies, coupled with dynamic partitioning between bulk phases and interfaces, induces rapid, and order‐of‐magnitude changes in oil–water interfacial tension. Surpassing the capabilities of conventional stimuli‐responsive surfactants, this transient, collaborative mechanism enables ...

Observations of narrow bipolar events reveal how lightning is initiated in thunderstorms

open access: yesNature Communications, 2016
A long-standing but fundamental question in lightning studies concerns how lightning is initiated inside storms, given the absence of physical conductors.

Fully Reshapeable and Recyclable Protein Hydrogels

open access: yesAdvanced Materials, EarlyView.
By taking advantage of the substantial stiffness contrast between protein hydrogels in their folded and unfolded protein states as well as reversible disulfide crosslinking, a robust and general strategy is reported to engineer fully reshapeable and recyclable protein hydrogels.

Estimation of Lightning Activity of Squall Lines by Different Lightning Parameterization Schemes in the Weather Research and Forecasting Model

open access: yesRemote Sensing, 2023
Based on three-dimensional lightning data and an S-band Doppler radar, a strong relationship was identified between lightning activity and the radar volume of squall lines. A detailed analysis of the squall line investigates the relationship following an
