Discreteness effects in a reacting system of particles with finite interaction radius [PDF]
, 2007 An autocatalytic reacting system with particles interacting at a finite distance is studied. We investigate the effects of the discrete-particle character of the model on properties like reaction rate, quenching phenomenon and front propagation, focusing

Frozen autocatalytic fronts in a radial flow
Physical Review ResearchAutocatalytic reaction-diffusion fronts are localized reaction zones propagating at a constant speed with a constant width. We show both theoretically and experimentally that, if the reactant Y of the autocatalytic reaction is injected radially at a ...

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system
FEBS Open Bio, EarlyView.An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Total Chiral Symmetry Breaking during Crystallization: Who needs a "Mother Crystal"? [PDF]
, 2005 Processes that can produce states of broken chiral symmetry are of particular interest to physics, chemistry and biology. Chiral symmetry breaking during crystallization of sodium chlorate occurs via the production of secondary crystals of the same ...

Origin of Autocatalytic Behavior of Water over CuZn Alloy in CO2 Hydrogenation
Chem & Bio EngineeringWater plays a significant role in CO2 hydrogenation, which is capable of accelerating the reaction in an autocatalytic manner, but the reason for water promotion in the system is still controversial.

Spatio-temporal patterns with hyperchaotic dynamics in diffusively coupled biochemical oscillators
Discrete Dynamics in Nature and Society, 1997 We present three examples how complex spatio-temporal patterns can be linked to hyperchaotic attractors in dynamical systems consisting of nonlinear biochemical oscillators coupled linearly with diffusion terms.

The chlorate-iodine-nitrous acid clock reaction. [PDF]
PLoS ONE, 2014 A new clock reaction based on chlorate, iodine and nitrous acid is presented. The induction period of this new clock reaction decreases when the initial concentrations of chlorate, nitrous acid and perchloric acid increase, but it is independent on the ...

Advanced Engineering Materials, EarlyView.This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Stationary distributions and condensation in autocatalytic CRN
, 2019 We investigate a broad family of non weakly reversible stochastically modeled reaction networks (CRN), by looking at their steady-state distributions. Most known results on stationary distributions assume weak reversibility and zero deficiency.

Nylon 6 polymerization in the solid state [PDF]
, 1982 The postcondensation of nylon 6 in the solid state was studied. The reactions were carried out on fine powder in a fluidized bed reactor in a stream of dry nitrogen in the temperature range 110-205°C and during 1-24 h. The solid-state polymerization (SSP)
