Applications of Biomaterials in Separators for Secondary Batteries

Carbon Energy, EarlyView.
In this review, biomaterial‐based separators are reviewed as sustainable alternatives to conventional polyolefin‐based separators. For 12 different natural polymers, spanning from Protista, Plantae, and Animalia, viable strategies for synthesizing biomass‐based separators are described.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Continuous flow electrochemical oxidative cyclization and successive functionalization of 2-Pyrrolidinones [PDF]

, 2021
2-Pyrrolidinones are important scaffolds found in numerous pharmacologically active compounds, such as brivaracetam and levetiracetam (antiepileptic drugs) or piracetam and pramiracetam (age-related memory impairment drugs).

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Water, Alcohols, Amines, and Amides as Formal Hydrogen‐Atom‐Transfer Reagents Through Activation With Redox‐Active Lewis Acids

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.
