Polyproline: A Synthetic Polypeptide With Unique Properties

Angewandte Chemie, EarlyView.
Poly‐L‐proline is a unique polypeptide distinguished by its well‐defined secondary structures and unusual thermal behavior. This mini review highlights recent advances in the synthesis of poly‐L‐proline by N‐carboxyanhydride (NCA) polymerization, the formation of structurally defined architectures and nanostructures, and emerging strategies that ...

Development of a small and transportable de-icing/anti-icing drone-mounted system. Part 1: System design

Drone Systems and Applications, 2022
The icing of aircraft on the ground is an important flight safety issue. Aircraft must be de-iced and anti-iced to remove and protect the aircraft from freezing and frozen contamination, respectively, before and during takeoff.

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li
