Correlation of the cyclic cracked round bar test and hydrostatic pressure test for unplasticized polyvinylchloride

open access: yesPolymer Testing, 2021
The applicability of the cracked round bar (CRB) test according ISO 18489 for the characterization of slow crack growth (SCG) in unplasticized polyvinylchloride (PVC–U) was analyzed by testing three PVC-U pipe compounds with different molecular mass ...

NADPH Oxidase Inhibition Promotes Brain Resilience by Attenuating Tauopathy and Neuroinflammation in Alzheimer's Disease [PDF]

open access: yesAdvanced Science
Alzheimer's disease (AD) associates closely associated with the activation of NADPH oxidase (Nox) isozymes. CRB‐2131, a novel oxadiazole derivative, is identified as a potently suppresses Nox isozymes. It inhibits reactive oxygen species production (ROS)
