Polyurethane Cascade Depolymerization by a Combination of Thermal Pretreatment and Enzymatic Hydrolysis

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
This study explored the cascade depolymerization of a polyether‐polyester polyurethane based on a combination of low‐temperature thermal treatment and enzymatic hydrolysis. Heat pretreatment changed the physicochemical properties of polyurethane, followed by cutinase‐catalyzed hydrolysis, leading to an increase in weight loss and the production of two ...

Effect of membrane penetration on liquefaction resistance

open access: yesEffect of membrane penetration on liquefaction resistance
The liquefaction of saturated sand is due to a negative dilatancy. In the cyclic triaxial test, a part of pore water squeezed from sample is transformed into the reduction of membrane penetration and so the perfect undrained test can not be performed. Consequently, the liquefaction resistance obtained by the cyclic triaxial test is evaluated apparently
