From Amino Acids to α‐Keto Acids via β‐Elimination and Transamination Initiates a Pathway to Prebiotic Reaction Networks

Angewandte Chemie International Edition, Accepted Article.
α‐Keto acids, such as pyruvate and glyoxylate, may have been critical in generating reaction networks at the origins of life due to their facile carbon‐carbon bond formation and their hydrolytic stability. However, demonstrated prebiotic sources of these small α‐keto acids have been limited by conditions required for their production which are not ...

Assessing the Thermo‐Oxidative Degradation of 6FDA‐Based Thermosetting Polyimides Using a Combination of Isothermal and Non‐Isothermal TGA

Journal of Applied Polymer Science, EarlyView.
ABSTRACT This study investigates and compares the thermal stability of two 6FDA‐based thermosetting polyimide formulations with varied amounts of internal crosslinkers. The baseline formulation is a commercially available polyimide with good resin transfer molding processability and a high glass transition temperature, Tg, in the range of 340°C–466°C ...
