Scandium Doping and Coating for Improving O3‐NaNi1/2Mn1/2O2 Electrode in Sodium Battery

open access: yesSmall, EarlyView.
Scandium incorporation into O3‐Na[Ni1/2Mn1/2]O2 enhances cycling stability through distinct bulk and interfacial mechanisms. Bulk Sc3+ doping stabilizes the lattice and suppresses the O′3 phase, while Sc2O3 coating mitigates interfacial degradation. Together, these strategies markedly improve long‐term performance, offering a pathway to design durable ...

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

open access: yesSmall, EarlyView.
A sprayable MXene‐loaded thermosensitive hydrogel was developed for postoperative melanoma treatment. Molecular simulations combined with experimental analyses demonstrated that polymer composition regulates MXene oxidation. The optimized hydrogel effectively preserved photothermal performance under physiological conditions, enabling efficient near ...

Unraveling the Mechanism for Phonon Based Heat Transport in Metal‐Organic Frameworks

open access: yesSmall, EarlyView.
Heat transport in metal‐organic frameworks arises from an interplay between particle‐like phonon propagation and wave‐like inter‐band coupling. Using machine‐learned potentials within a unified phonon‐transport framework based on the Wigner transport theory, we reveal how differences in phonon lifetimes and phonon tunneling effects determine the ...

Remote Plasma‐Enabled Vertical Asymmetry Engineering of 2D PtSe2 via Phase‐Preserving Chalcogen Exchange

open access: yesSmall, EarlyView.
Remote H2S plasma enables temperature‐controlled chalcogen exchange in PtSe2. At 50°C, selective top‐surface Se‐to‐S substitution yields Janus PtSSe while preserving the layered framework, whereas treatment at 200°C promotes further sulfur incorporation and diffusion to form PtS2.

Inertial oscillation of a vertical rotating draft with application to a supercell storm [PDF]

open access: yes, 1992
An analytic model (vertical rotating draft) which includes the gross features of a supercell storm on an f-plane, undergoes an inertial oscillation that appears to have been overlooked in previous analytic and numerical models.

Observations of Right-Moving Supercell Motion Forecast Errors

open access: yes, 2018
Two shear-based supercell motion forecast methods are assessed to understand how each method performs under differing environmental conditions for observed right-moving supercells.

The impact of several hail parameters on simulated supercell storms

open access: yes, 2001
Most modeling studies of supercell storms neglect the ice phase. However, supercells are often prolific producers of hail and extend deep enough in the troposphere that active participation by the ice phase in storm dynamics would be expected. Therefore, the sensitivity of simulated supercell characteristics to variations in the settings of several ice

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

open access: yesHigh Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Distributions of Short‐Duration High‐Intensity Precipitation Events in the United States Under Intermediate and Pessimistic Climate Change Scenarios

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Under a warming climate, the magnitude and frequency of intense precipitation are expected to increase globally, on average. However, changes in the regional variability of short‐duration high‐intensity (SDHI) precipitation across the contiguous United States—both temporally and spatially—remain uncertain, and most projections rest on ...
