A chemical probe technique for the determination of reactive halogen species in aqueous solution: Part 1 – bromide solutions [PDF]
Atmospheric Chemistry and Physics, 2006 Reactive halogen species (X*=X•, •X2-, X2 and HOX, where X=Br, Cl, or I) in seawater, sea-salt particles, and snowpacks play important roles in the chemistry of the marine boundary layer.

Modelling the effects of the October 1989 solar proton event on mesospheric odd nitrogen using a detailed ion and neutral chemistry model [PDF]
Annales Geophysicae, 2002 Solar proton events and electron precipitation affect the concentrations of middle atmospheric constituents. Ionization caused by precipitating particles enhances the production of important minor neutral constituents, such as nitric oxide ...

Circular Stochastic Fluctuations in SIS Epidemics with Heterogeneous Contacts Among Sub-populations
, 2011 The conceptual difference between equilibrium and non-equilibrium steady state (NESS) is well established in physics and chemistry. This distinction, however, is not widely appreciated in dynamical descriptions of biological populations in terms of ...

Shape optimization of a showerhead system for the control of growth uniformity in a MOCVD reactor using CFD-based evolutionary algorithms [PDF]
, 2009 A steady state, laminar flow coupled with heat transfer, gas-phase and surface chemistry, is numerically solved for the optimal design of a showerhead gas delivery system in an axis-symmetrical MOCVD reactor.

Hydroxyl radical in/on illuminated polar snow: formation rates, lifetimes, and steady-state concentrations [PDF]
Atmospheric Chemistry and Physics, 2016 While the hydroxyl radical (•OH) in the snowpack is likely a dominant oxidant for organic species and bromide, little is known about the kinetics or steady-state concentrations of •OH on/in snow and ice.

The Formation of Large Hydrocarbons and Carbon Clusters in Dense Interstellar Clouds [PDF]
, 1997 Current gas-phase models of dense cloud chemistry contain molecules through approx 10 atoms in size. We have extended two current reaction networks to include unsaturated hydrocarbons and bare carbon clusters up to 64 carbon atoms in size.

Metallicity dependence of the H/H$_2$ and C$^+$/C/CO distributions in a resolved self-regulating interstellar medium [PDF]
, 2021 We study the metallicity dependence of the H/H$_2$ and C$^+$/C/CO distributions in a self-regulated interstellar medium (ISM) across a broad range of metallicities ($0.1 < Z/Z_\odot < 3$).

Spatial distribution of small hydrocarbons in the neighborhood of the Ultra Compact HII region Monoceros R2 [PDF]
, 2013 We study the chemistry of small hydrocarbons in the photon-dominated regions (PDRs) associated with the ultra-compact HII region Mon R2. Our goal is to determine the variations of the abundance of small hydrocarbons in a high-UV irradiated PDR and ...
