Upcycling waste polystyrene to adipic acid through a hybrid chemical and biological process

Nature Communications
Oxidative catalytic depolymerization of polystyrene (PS) can produce benzoic acid, but the annual consumption of benzoic acid is ~40 times lower than PS.

Better Material Properties and Faster Catalyzed Chemical Recycling for Poly(L‐Lactide) Using a Simple Commercial Glycerol Ethoxylate Additive

Chemistry – A European Journal, EarlyView.
Glycerol ethoxylate (GEO), a branched ethylene glycol derivative, both toughens commercial PLLA and accelerates its chemical recycling to L‐lactide. The lead sample, containing 10 wt.% GEO, shows 9x higher elongation at break and 6x higher tensile toughness than pure PLLA. The GEO–PLLA samples are efficiently chemically recycled to L‐lactide, even when

Resistance of Kapok Fibers (Ceiba pentandra) to Biotic and Abiotic Degradation: Evaluation by SEM, FTIR, Py-GC/MS, and Colorimetry

Journal of Natural Fibers
Kapok fibers (Ceiba pentandra) are considered sustainable materials, but their durability under stress is poorly understood. This study examined their resistance to abiotic (UV radiation, heat) and biotic (Aspergillus niger) degradation.

Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Branched-chain amino acids contribute to diabetic kidney disease progression via PKM2-mediated podocyte metabolic reprogramming and apoptosis

Nature Communications
Approximately 30-40% of patients with diabetes develop diabetic kidney disease (DKD). Identifying decisive factors for DKD initiation is crucial. Here, we observed that glomerular podocytes in male and female patients with DKD and db/db mice specifically

Mitochondria and the Actin Cytoskeleton in Neurodegeneration

Cytoskeleton, EarlyView.
ABSTRACT Mitochondrial dysfunction and cytoskeletal disorganization are widely recognized hallmarks of neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS).
