Weakly Solvating Electrolytes for Lithium and Post‐Lithium Rechargeable Batteries: Progress and Outlook

Advanced Energy Materials, EarlyView.
Weakly solvating electrolytes (WSEs) use anion‐dominated solvation to form stable interphase layers, overcoming energy density and lifespan limitations. This review clarifies their design, anion‐mediated interface regulation, and compatibility with lithium/post‐lithium systems, distinguishing them from conventional electrolytes, high concentration ...

Benefit from Biomass Boiler Emissions to Increase Greenhouse CO2 Levels for Optimal Growth and Yield in Tomato, Cucumber, and Strawberry

Advanced Energy and Sustainability Research, EarlyView.
Using CO2‐rich polluting gases in greenhouse plant cultivation has proven to be a promising technique for stimulating plants while reducing emissions to the atmosphere. The use of an experimental biofilter proves to be effective in retaining most of the toxic particles. The alteration of physiological and metabolic parameters shows an adaptation of the
