Valorization of Mattress Waste into Thermoplastic Polyurethane (TPU)‐Based Composites for Footwear Midsoles and Outsoles

Macromolecular Materials and Engineering, Volume 311, Issue 7, July 2026.
Mattress‐derived recycled polyurethane is combined with thermoplastic polyurethane to create footwear materials through two processing routes: compression‐molded midsole blends and extrusion/FFF‐processed fiber‐reinforced outsole composites. The resulting materials show tunable cushioning, abrasion resistance, and ice traction, highlighting a practical

Racemisation of Amino Acids: From Synthetic Challenge to Biological Significance

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Racemisation, once considered an undesirable synthetic side reaction, also occurs naturally in amino acids and influences biological processes. Evidence links stereochemical conversion to ageing, protein turnover, and cellular development. This review examines mechanisms, control strategies in synthesis, applications and implications in physiology ...

Polyurethane Depolymerization With Alkyl, Aryl, and Mixed Carbonates

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
The depolymerization of polyurethane foams strongly depends on carbonate structure. Aryl carbonates improve hard‐segment solubility but generate side products. Alkyl carbonates give cleaner products yet suffer from limited hard‐block solubility and require anisole as a cosolvent. Mixed carbonate systems balance these effects, improving solubility while

Lipase-catalyzed acidolysis of butterfat with oleic acid: characterization of process and product

Enzyme and Microbial Technology, 1998
The modification of anhydrous butterfat via interesterification reactions with oleic acid catalyzed by a lipase from Mucor circinelloides immobilized by adsorption onto hydrophobic hollow fibers is described. A reasonable degree of incorporation of free (externally added) oleic acid into the triacylglycerols of butterfat has been achieved while short ...

Mechanistic and Kinetic Investigation of Synergistic Methanesulfonic and DL–Malic Acids Leaching System for Battery Cathode Recycling

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Organic acids have been considered as eco‐friendly leaching agents, but their utilization has been limited due to low pulp density and high costs. In this study, methanesulfonic acid (MSA), with high acidity, and DL‐malic acid (MA), with excellent chelating ability and cost‐effectiveness, were combined to develop a novel hybrid organic ...
