Coexistence of Decaying and Decayless Kink Oscillations in a Bundle of Coronal Loops Triggered by an X6.3 Solar Flare

The Astrophysical Journal Letters
We report the coexistence of decaying and decayless kink oscillations within a single bundle of coronal loops during the X6.3-class solar flare on 2024 February 22.

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

Battery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Interface Engineering Remarkably Improves the Stability of Fe‐Based Electrode for Alkaline Water Electrolysis at Industrial Ampere‐Level Current Density

Carbon Energy, EarlyView.
Interface engineering improves the stability of iron‐based industrial oxygen evolution catalysts by more than 2000 times at ampere‐level current density. ABSTRACT Iron‐based self‐supported electrocatalysts offer cost‐effective oxygen evolution activity but suffer from severe stability degradation under industrial operation.

The $n {-} \bar n$ oscillations in neutron fluxes running from Sun to Earth

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The process of $n {-} \bar n$ oscillations in the solar cosmic-rays is considered. It is shown that it has high intensity with respect to the analogic processes on the Earth $(I_{c{-}r}/I_{Earth} \propto 10^8)$, because magnetic field strongly suppresses

Wurtzite‐Chalcopyrite Crystal Polymorphism in CuGaS2 Nanoparticles Dictates the Localized Surface Plasmon Resonance

Chemistry – A European Journal, EarlyView.
Crystal phase‐ and size‐selective synthesis of chalcopyrite and wurtzite‐type CuGaS2 NPs was successfully achieved. They exhibited clear LSPR in the NIR region. The extinction coefficient of chalcopyrite was three times higher than that of wurtzite due to its greater symmetry and dipole moment. These results will enable precise control of the plasmonic

Photometric Diagnostic of the Sheath Dynamics and Electron Density Trends in Single and Dual Frequency CCRF Argon Plasmas

Contributions to Plasma Physics, EarlyView.
ABSTRACT A methodological study is presented on a noninvasive photometric diagnostic for determining trends in electron density and sheath dynamics in single (1f) and a dual (2f) radio frequency capacitively coupled (CCRF) argon plasmas. The 1f discharges are operated at 13.56 and 27.12 MHz, respectively, while the 2f discharge is driven by both ...
