Optimizing the time of incubation of an anion exchange membrane inserted into the soil to use in studies of monitoring soil nitrate levels [PDF]

open access: yes, 2010
Ann anion exchange membrane (AEM) is a solid organic polymer that has a positive electrostatic charge, which is saturated by the addition of a counter ion, such as bicarbonate (HCO3), before use.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

open access: yesAdvanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.
