Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

Advanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Stratified atmospheric flow modeling

AIP Conference Proceedings, 2012
This contribution considers the influence of stratification on laminar and incompressible flow. As a test problem, 2D and 3D cavity flow is modeled and the results compared with those published previously. The influence of stratification is also examined in the case of 2D flow past an obstacle located inside a channel.

Modelling atmospheric flows

Acta Numerica, 2007
This article demonstrates how numerical methods for atmospheric models can be validated by showing that they give the theoretically predicted rate of convergence to relevant asymptotic limit solutions. This procedure is necessary because the exact solution of the Navier–Stokes equations cannot be resolved by production models.
