Large Solvent‐Dependent Rate Enhancement of Autocatalytic Hydrolysis of Alkyl and Aryl Thiosulfates [PDF]

open access: yesChemistryOpen
The hydrolysis of alkyl and aryl thiosulfates (Bunte salts), to produce the corresponding thiol and bisulfate ion, is autocatalytic in the absence of added acid and proceeds at greatly accelerated rates in organic solvents at room temperature relative to

Autocatalytic Sets and Assembly Theory: A Toy Model Perspective [PDF]

open access: yesEntropy
Assembly Theory provides a promising framework to explain the complexity of systems such as molecular structures and the origins of life, with broad applicability across various disciplines.

Crystallization-driven template autocatalysis induces mirror symmetry breaking and amplification [PDF]

open access: yesNature Communications
A plausible hypothesis for the origin of biological homochirality invokes chiral symmetry breaking, transfer, and amplification driven by autocatalysis. Here we experimentally demonstrate that crystallization-driven template autocatalysis (CDTA) induces ...

Driving forces in the origins of life [PDF]

open access: yesOpen Biology, 2021
What were the physico-chemical forces that drove the origins of life? We discuss four major prebiotic ‘discoveries’: persistent sampling of chemical reaction space; sequence-encodable foldable catalysts; assembly of functional pathways; and encapsulation

Martensite’s Logistic Paradigm

open access: yesMaterials Research, 2021
This work introduces a deterministic approach to the martensite transformation curve. Martensite is a nucleation-controlled transformation that has two characteristics: autocatalysis and auto-accommodation.

Kinetic and thermodynamic investigation on diffusion-limited crosslinking reaction behaviors of peroxide-induced low-density polyethylene

open access: yesPolymer Testing, 2023
Crosslinking reaction behaviors can determine the network morphology and further influence macroscopic properties of polymers, while the current comprehension about crosslinking reaction behaviors of peroxide-induced low-density polyethylene (PLDPE) is ...

Martensite Transformation Intergrain and Intragrain Autocatalysis in Fe-Ni alloys [PDF]

open access: yesMaterials Research, 2017
This work presents a consolidated view of the autocatalysis, thermal and entropic effects in martensitic transformation of polycrystalline Fe-31wt%Ni-0.02wt%C, which has been a standard material for the investigation of fundamental aspects of the ...

Autocatalysis, Entropic Aspects and the Martensite Transformation Curve in Iron-Base Alloys [PDF]

open access: yesMaterials Research, 2017
This study advances a methodology that consolidates the description of time-dependent (isothermal) as well as time-independent (athermal) martensitic transformation curves.

On the Regulated Nuclear Transport of Incompletely Spliced mRNAs by HIV-Rev Protein: A Minimal Dynamic Model

open access: yesMathematics, 2022
A kinetic model for the HIV-1 Rev protein is developed by drawing upon mechanistic information from the literature to formulate a set of differential equations modeling the behavior of Rev and its various associated factors over time.

Influence of the Weak Nuclear Force on Metal-Promoted Autocatalytic Strecker Synthesis of Amino Acids: Formation of a Chiral Pool of Precursors for Prebiotic Peptide and Protein Synthesis

open access: yesLife, 2023
Natural chiral amino acids typically adopt an L structural configuration. While a preference for specific molecular chiralities is observed throughout biology and cellular chemistry, the origins of this preference are unclear.
