Advanced Functional Materials, EarlyView.Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

Who Realizes a PSS?: An Organizational Framework for PSS Development
Procedia CIRP, 2015 AbstractIn manufacturing, Product-Service Systems (PSS) that create value by coupling a physical product and a service have been attracting attention. According to this background, many researchers have proposed PSS development methods that provide guidance on HOW TO realize a PSS.

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Advanced Functional Materials, EarlyView.A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Strategies for Diagnosis of Diseases in Pigs Using Molecular Markers Review
Scientific Papers Animal Science and Biotechnologies, 2023 In certain breeds of pigs were identified the porcine stress syndrome (PSS) that determine the appearance of some carcasses inadequate for processing. Because PSS can be triggered by halothane, the gene responsible for the syndrome is often referred to ...
