Synergistic Cu‐Fe Interactions Enhance Phase Transformation Kinetics Toward High‐Performance CuFeS2‐Based All‐Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
CuFeS2 is found to induce the formation of intermediate phases, highlighting a strong Cu–Fe synergistic effect during conversion reactions in lithium all‐solid‐state batteries (Li‐SSBs). The integrated reaction pathway effectively suppresses phase separation and accelerates reaction kinetics, leading to enhanced electrochemical reversibility and ...

Submicron Metasurface Reconfigured Multiband Smart Windows

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

Composition of Energetic Solar Particles [PDF]

open access: yes, 1972
19-24Present state of our knowledge on the composition of energetic solar particles is reviewed with particular reference to the direct measurements of these particles with sounding rockets and balloons during solar cosmic ray events.

Energetic Particles from Quasi-separatrix Layers and Current Sheets at the Sun

open access: yesThe Astrophysical Journal
Quasi-separatrix layers (QSLs) at the Sun are created in regions where channels of open magnetic flux have footpoints near regions of large-scale closed magnetic flux. These regions show rapid changes in curvature and field strength.

Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens

open access: yesAdvanced Healthcare Materials, EarlyView.
High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Are Solar Energetic Particles an Accelerated Sample of Solar Wind? [PDF]

open access: yes, 2001
In the current picture of gradual solar energetic particle (SEP) events, the acceleration is believed to take place at a shock driven by a coronal mass ejection as it moves through the corona and out into the solar wind.

A new method of studying the relation between ionization rates and radio-wave absorption in polar-cap absorption events [PDF]

open access: yes, 2005
International audienceDuring polar-cap absorption events, which are caused by the incidence of energetic solar protons, the high-latitude ionospheric D region is extended down to relatively low altitudes. While the incoming proton fluxes may be monitored

The “FIP Effect” and the Origins of Solar Energetic Particles and of the Solar Wind [PDF]

open access: yesSolar Physics, 2018
We find that the element abundances in solar energetic particles (SEPs) and in the slow solar wind (SSW), relative to those in the photosphere, show different patterns as a function of the first ionization potential (FIP) of the elements. Generally, the SEP and SSW abundances reflect abundance samples of the solar corona, where low-FIP elements ...
