Autocatalysis and Blood Coagulation [PDF]

Nature, 1939
THE autocatalytic behaviour of blood coagulation is thought, by several authors, to be due to the autocatalytic formation of thrombin from its precursor prothrombin1. So far, thrombin seems similar to the enzymes studied by Northrop and co-workers2.

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Stability of racemic and chiral steady states in open and closed chemical systems

, 2008
The stability properties of models of spontaneous mirror symmetry breaking in chemistry are characterized algebraically. The models considered here all derive either from the Frank model or from autocatalysis with limited enantioselectivity.

Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

steel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

Navigating the Chemical Space of HCN Polymerization and Hydrolysis: Guiding Graph Grammars by Mass Spectrometry Data

Entropy, 2013
Polymers of hydrogen cyanide and their hydrolysis products constitute a plausible, but still poorly understood proposal for early prebiotic chemistry on Earth.

Coarse‐Grained Molecular Dynamics Simulations of Oxidative Aging and Stabilization in Polymer Melts With Primary Antioxidants: Effects of Antioxidant Concentration and Molecular Architecture

Journal of Vinyl and Additive Technology, EarlyView.
Antioxidant type and concentration govern both the rate and spatial heterogeneity of oxidative aging in polymer melts. Higher antioxidant‐group concentration prolongs the induction and reaction time scales, while the BHT‐type antioxidant provides stronger and more homogeneous stabilization than the Irganox1010‐type antioxidant because of its more ...

Prebiotic Competition between Information Variants, With Low Error Catastrophe Risks

Entropy, 2015
During competition for resources in primitive networks increased fitness of an information variant does not necessarily equate with successful elimination of its competitors.

Existence and Stability of Propagating Fronts for an Autocatalytic Reaction-Diffusion System

, 1997
We study a one-dimensional reaction-diffusion system which describes an isothermal autocatalytic chemical reaction involving both a quadratic (A + B -> 2B) and a cubic (A + 2B -> 3B) autocatalysis.
