Novel Bio‐Based Polyurethane Elastomers Customizable for Orthopedic Devices: Toughness, Rapid Degradability, and Safety

open access: yesSusMat, EarlyView.
ABSTRACT Given the increasing global demand for sustainable materials and growing concerns over the depletion of petrochemical resources, we report the synthesis of an amorphous bio‐derived polyester diol, and this diol was polymerized with various isocyanates and butanediol, yielding a novel series of bio‐based polyurethane elastomers (BPUEs). Notably,

Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds

open access: yesThe Chemical Record, EarlyView.
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

APU diaphragm testing. Test plan [PDF]

open access: yes
Auxiliary Power Unit (APU) fuel (hydrazine) tanks have had to be removed from the Columbia Shuttle (OV-102) because they have been in service for 11 years, which is the limit of their useful life. As part of an effort to determine whether the useful life

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, EarlyView.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...
