Langevin Dynamics with Variable Coefficients and Nonconservative Forces: From Stationary States to Numerical Methods

Entropy, 2017
Langevin dynamics is a versatile stochastic model used in biology, chemistry, engineering, physics and computer science. Traditionally, in thermal equilibrium, one assumes (i) the forces are given as the gradient of a potential and (ii) a fluctuation ...

An iterative dynamic chemical stiffness removal method for reacting flow simulations

Propulsion and Energy
An iterative dynamic chemical stiffness removal method (IDCSR) based on quasi-steady-state approximation (QSSA) is proposed. The IDCSR method is built on a previously developed non-iterative method which has proved to work well for small timestep sizes ...

A note on flow behavior in axially-dispersed plug flow reactors with step input of tracer

Atmospheric Environment: X, 2019
Atmospheric chemistry studies are frequently conducted in flow reactors, such as the potential aerosol mass (PAM) reactor. To characterize the flow condition in such a reactor, an axially-dispersed plug flow reactor (AD-PFR) model has been applied to ...

Coordination-Driven Self-Assembly of Silver(I) and Gold(I) Rings: Synthesis, Characterization, and Photophysical Studies

Frontiers in Chemistry, 2019
In this work, we investigate the self-assembly between Ag(I) and Au(I) centers and pyridyl donors to form hexagonal metallacycles and related linear complexes.

Dielectrically Monitored Flow Synthesis of Functional Vaccine Adjuvant Mixtures via Microwave-Assisted Catalytic Chain Transfer Processing

Chemistry
A novel flow process to produce low-molecular-weight (Mwt) methacrylate oligomer mixtures that have potential as vaccine adjuvants and chain transfer agents (CTAs) is reported. The chemistry and process were designed to significantly reduce the number of

Toward Multi-Parametric Porous Silicon Transducers Based on Covalent Grafting of Graphene Oxide for Biosensing Applications

Frontiers in Chemistry, 2018
Graphene oxide (GO) is a two-dimensional material with peculiar photoluminescence emission and good dispersion in water, that make it an useful platform for the development of label-free optical biosensors. In this study, a GO-porous silicon (PSi) hybrid

Deuterium plasma induced preferential erosion in ultra-high temperature ceramics TiB2 and ZrB2

Nuclear Fusion
Steady-state deuterium plasma exposures were performed on ultra-high temperature ceramics titanium diboride (TiB _2 ) and zirconium diboride (ZrB _2 ) using the PISCES-RF linear plasma device (LPD) as early screening for first wall, plasma-facing ...
