Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

Journal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

Reconstruction of native cellular microanatomy in a novel bioengineered full thickness human nasal mucosal construct

Journal of Anatomy, EarlyView.
Bioengineered tissue constructs are vital technologies employed in in vitro testing of both fundamental biological principles and industrial screening practices. Current approaches to modelling the nasal mucosa in vitro are not representative and are associated with limitations that impact their reliability and predictive value.

Plastics and labor: The case of disposable medical plastics

Medical Anthropology Quarterly, EarlyView.
Abstract Plastics are ubiquitous in the contemporary practice of medicine, where they are tied to notions of hygiene and quality of care. However, when plastics first infiltrated global medical practice, they did so because of considerations related to patient comfort and durability.
