Enhancing the solvent resistance and thermomechanical properties of thermoplastic acrylic polymers and composites via reactive hybridisation

open access: yesMaterials & Design, 2021
This work demonstrates the use of an engineering thermoplastic, poly(phenylene ether) (PPE) to enhance the solvent resistance and thermomechanical properties of liquid acrylic resin-based composites by a reactive hybridisation route.

pyJac: analytical Jacobian generator for chemical kinetics [PDF]

open access: yesComput. Phys. Comm. 215 (2017) 188-203, 2016
Accurate simulations of combustion phenomena require the use of detailed chemical kinetics in order to capture limit phenomena such as ignition and extinction as well as predict pollutant formation. However, the chemical kinetic models for hydrocarbon fuels of practical interest typically have large numbers of species and reactions and exhibit high ...

Intergranular diffusion rates from the analysis of garnet surfaces: implications for metamorphic equilibration [PDF]

open access: yes, 2017
Novel approaches to garnet analysis have been used to assess rates of intergranular diffusion between different matrix phases and garnet porphyroblasts in a regionally metamorphosed staurolite-mica-schist from the Barrovian-type area in Scotland.

FMO3-LCMO study of electron transfer coupling matrix element and pathway: Application to hole transfer between two triptophanes through cis- and trans-polyproline-linker systems [PDF]

open access: yesJournal of Chemical Physics 145, 114103 (2016), 2016
The linear-combination of fragment molecular orbitals with three-body correction (FMO3-LCMO) is examined for electron transfer (ET) coupling matrix elements and ET pathway analysis, with application to hole transfer between two triptophanes bridged by cis- and trans-polyproline linker conformations.
