3D non-LTE line formation in the solar photosphere and the solar oxygen abundance

open access: yes, 1995
We study the formation of O I and OH spectral lines in three-dimensional hydrodynamic models of the solar photosphere. The line source function of the O I 777 nm triplet is allowed to depart from local thermodynamic equilibrium (LTE), within the two ...

Solid Porous Materials for Selective Capture and Separation of Sulfur Hexafluoride (SF6)

open access: yesChemPlusChem, EarlyView.
The effective capture of sulfur hexafluoride (SF6), one of the most potent greenhouse gases, is a critical environmental challenge. This study evaluates porous materials—coconut shell‐derived activated carbons, a commercial activated carbon monolith, and a metal‐organic framework—for capturing SF6.

Ultrafast Studies of Different Oxidation and Protonation States of Rhodamine 6G and Implications for Photocatalysis

open access: yesChemPhotoChem, EarlyView.
Three preparation methods of the rhodamine 6G radical R6G• are discussed. R6G• plays a vital role in photocatalysis where upon excitation, it donates an electron and regenerates R6G+. R6G+ can furthermore be reversibly deprotonated twice. In basic media, oxygen accelerates R6G• oxidation to R6G+, which is then deprotonated rapidly.

Enhancing Cyclic Performance of Lithium–Aluminum Layered Double Hydroxides Type Adsorbents via Vanadium Anions Intercalation for Li+ Extraction from Sulfate‐Type Brines

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The new aluminum‐based lithium adsorbent synthesized by the one‐step co‐precipitation method has a high adsorption capacity and stability, and at the same time, inhibits the formation of gibbsite during the desorption process; it is able to reverse gibbsite during the adsorption phase to ensure structural stability.
