3‐hydroxybutyrate in the brain: Biosynthesis, function, and disease therapy

Brain-X, 2023
3‐hydroxybutyrate (3HB), or BHB, is an anionic small molecule acid metabolite with a hydroxyl group. 3HB is the major ketone body that is distributed in the human brain and its primary energy source when glucose is absent.

Can Biomass Mastication Assist the Downstreaming of Polyhydroxyalkanoates Produced from Mixed Microbial Cultures?

Molecules, 2023
Polyhydroxyalkanoates (PHAs) are natural polyesters which biodegrade in soils and oceans but have more than double the cost of comparable oil-based polymers. PHA downstreaming from its biomass represents 50% of its overall cost.

Thermally Processable, Transparent, Mechanically Tunable and Robust Bioplastics From Wastepaper

Advanced Science, EarlyView.
Unlike conventional inefficient or low‐value wastepaper recycling, a directional transformation strategy is employed to convert whole wastepaper into intact bioplastics with tunable mechanical properties in our work. These bioplastics can be processed into flexible bags or rigid containers and exhibit high transparency, water resistance, repairability,
