Characterizing and contrasting structural proton transport mechanisms in azole hydrogen bond networks using ab initio molecular dynamics [PDF]
J. Phys. Chem. Lett. 2021, 12, 36, 8749-8756, 2021 Imidazole and 1,2,3-triazole are promising hydrogen-bonded heterocycles that conduct protons via a structural mechanism and whose derivatives are present in systems ranging from biological proton channels to proton exchange membrane fuel cells. Here, we leverage multiple time-stepping to perform ab initio molecular dynamics of imidazole and 1,2,3 ...

Energy per particle of nuclear and neutron matter from subleading chiral three-nucleon interactions [PDF]
Phys. Rev. C 103, 054002 (2021), 2021 We derive from the subleading contributions to the chiral three-nucleon interaction [published in Phys.~Rev.~C77, 064004 (2008) and Phys.~Rev.~C84, 054001 (2011)] their first-order contributions to the energy per particle of isospin-symmetric nuclear matter and pure neutron matter in an analytical way.

Performance Analysis of Novel Propellant Oxidizers using Molecular Modelling and Nozzle Flow Simulations [PDF]
, 2022 The primary target of this paper is to present novel compounds in view of their possible use as oxidizers in propulsion applications using molecular modeling calculations and supersonic flow simulations. Carbon-based heterocyclic compounds tend to have strained molecular structures leading to high heats of formation and energetic behavior.
