Investigation of ion-electrode interactions of linear polyimides and alkali metal ions for next generation alternative-ion batteries.

Organic electrode materials offer unique opportunities to utilize ion-electrode interactions to develop diverse, versatile, and high-performing secondary batteries, particularly for applications requiring high power densities. However, a lack of well-defined structure-property relationships for redox-active organic materials restricts the advancement of the field. Herein, we investigate a family of diimide-based polymer materials with several charge-compensating ions (Li, Na, K) in order to systematically probe how redox-active moiety, ion, and polymer flexibility dictate their thermodynamic and kinetic properties.

Biocompatible metal-organic frameworks for the storage and therapeutic delivery of hydrogen sulfide.

Hydrogen sulfide (HS) is an endogenous gasotransmitter with potential therapeutic value for treating a range of disorders, such as ischemia-reperfusion injury resulting from a myocardial infarction or stroke. However, the medicinal delivery of HS is hindered by its corrosive and toxic nature. In addition, small molecule HS donors often generate other reactive and sulfur-containing species upon HS release, leading to unwanted side effects.
