A spheroidal weathering model coupling porewater chemistry to soil thicknesses during steady-state denudation [PDF]
Earth and Planetary Science Letters, 2006 Abstract Spheroidal weathering, a common mechanism that initiates the transformation of bedrock to saprolite, creates concentric fractures demarcating relatively unaltered corestones and progressively more altered rindlets. In the spheroidally weathering Rio Blanco quartz diorite (Puerto Rico), diffusion of oxygen into corestones initiates oxidation ...

A steady-state continuous flow chamber for the study of daytime and nighttime chemistry under atmospherically relevant NO levels [PDF]
Atmospheric Measurement Techniques, 2018 Experiments performed in laboratory chambers have contributed significantly to the understanding of the fundamental kinetics and mechanisms of the chemical reactions occurring in the atmosphere. Two chemical regimes, classified as high-NO vs.

Interpretation of NO3–N2O5 observation via steady state in high-aerosol air mass: the impact of equilibrium coefficient in ambient conditions [PDF]
Atmospheric Chemistry and Physics, 2022 Steady-state approximation for interpreting NO3 and N2O5 has large uncertainty under complicated ambient conditions and could even produce incorrect results unconsciously.

Reciprocal Sum Expression for Steady-state Kinetics —Enzyme Reactions and Voltammetry—
Electrochemistry, 2022 Steady-state experiments are often conducted to understand complicated cases in chemistry, since the kinetics does not have a time valuable and allows simple modeling of the reactions.

The atmospheric chemistry box model CAABA/MECCA-3.0 [PDF]
Geoscientific Model Development, 2011 We present version 3.0 of the atmospheric chemistry box model CAABA/MECCA. In addition to a complete update of the rate coefficients to the most recent recommendations, a number of new features have been added: chemistry in multiple aerosol size bins;

Dramatic effect of fluid chemistry on cornstarch suspensions: linking particle interactions to macroscopic rheology [PDF]
, 2017 Suspensions of cornstarch in water exhibit strong dynamic shear-thickening. We show that partly replacing water by ethanol strongly alters the suspension rheology.

Desorption processes in molecular clouds: quasi-steady-state chemistry [PDF]
Monthly Notices of the Royal Astronomical Society, 1993 The effects of mantle desorption due to cosmic rays on the chemistry of interstellar clouds are modelled. Two desorption mechanisms are considered - direct cosmic ray heating of dust grains and cosmic ray induced photodesorption. Their effects at densities typical of a molecular cloud and a dense core are investigated.

Effects of biogenic nitrate chemistry on the NOx lifetime in remote continental regions [PDF]
Atmospheric Chemistry and Physics, 2012 We present an analysis of the NOx budget in conditions of low NOx (NOx = NO + NO2) and high biogenic volatile organic compound (BVOC) concentrations that are characteristic of most continental boundary layers.
