Highly Polarized Type III Storm Observed with Parker Solar Probe

The Astrophysical Journal Letters
The Parker Solar Probe (PSP) spacecraft observed a large coronal mass ejection (CME) on 2022 September 5, shortly before closest approach during the 13th PSP solar encounter.

Electrochemical Carbon Dioxide Reduction to Methanol on Copper‐Based Catalysts: Mechanistic Insights and Industrial Prospects

Advanced Materials, EarlyView.
This review presents a focused and integrated perspective on copper‐based catalysts for the selective electrochemical reduction of CO2 to methanol. It elucidates active site dynamics, mechanistic pathways, and structure–activity relationships, while connecting fundamental insights with catalyst design, reactor engineering, and techno‐economic ...

Plasma Instability in Front of Ejected Energetic Electrons and Type III Solar Radio Bursts

The Astrophysical Journal
Type III radio bursts are signatures of the fluxes of near-relativistic electrons ejected during solar flares. These bursts are frequently observed by spacecraft such as the Parker Solar Probe. It has been traditionally believed that these electron beams

High‐Performance Zero‐Gap Glycerol‐Fed Electrolyzer for C3 Chemicals and Hydrogen Production

Advanced Materials, EarlyView.
This work presents a dynamic, self‐regulating operation strategy that enables selective glycerol electrooxidation in the OER‐free regime, co‐producing C3 chemicals and hydrogen at cell voltages below 1.25 V. Voltage‐ and temperature‐resolved analyses define optimal operating conditions, achieving a sustained current density of 500 mA cm−2 at ∼1.21 V ...

Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control

Advanced Materials, EarlyView.
Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.
