Stress granules attenuate protein nanoparticle induced osmotic imbalance via membrane potential restoration [PDF]

Scientific Reports
Stress granules (SGs) are biomolecular condensates formed in response to stress stimuli, and they can alter intracellular protein particles. Here, SG assembly was noted to effectively stabilize intermediate filament tension, intracellular osmolarity, Ca2+

Added-Value Chemicals from Lignin Oxidation

Molecules, 2021
Lignin is the second most abundant component, next to cellulose, in lignocellulosic biomass. Large amounts of this polymer are produced annually in the pulp and paper industries as a coproduct from the cooking process—most of it burned as fuel for energy.

Direct conversion of lignin to functionalized diaryl ethers via oxidative cross-coupling

Nature Communications, 2023
Efficient valorization of lignin, a sustainable source of functionalized aromatic products, would reduce dependence on fossil-derived feedstocks. Oxidative depolymerization is frequently applied to lignin to generate phenolic monomers.

Insight into Relationship between Thermal Dissolution of Low-Rank Coals and Their Subsequent Oxidative Depolymerization

Energies, 2021
Oxidative depolymerization of low-rank coals is promising for obtaining benzene carboxylic acids (BCAs). However, it is hindered by the low yield of BCAs along with a large number of alphatic acids.
