The Triplet Genetic Code had a Doublet Predecessor

open access: yes, 2004
Information theoretic analysis of genetic languages indicates that the naturally occurring 20 amino acids and the triplet genetic code arose by duplication of 10 amino acids of class-II and a doublet genetic code having codons NNY and anticodons ...

Electron Transport Bilayer Design for Perovskite‐Based Tandem Solar Cells Using Thermal Evaporation

open access: yesChemistry–Methods, EarlyView.
We provide a comprehensive explanation of designing a bi‐layer electron transport layer with a fullerene layer using the evaporation method in inverted perovskite solar cells (PSCs) and perovskite‐based tandem solar cells (PTSCs). Furthermore, we provide candidate materials for a bi‐layer and suggest a fullerene/SnO2 bi‐layer configuration for high ...

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Metabolic changes during cardiac regeneration in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Cross‐Coupling Reactions in Aqueous Micellar Media

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Aqueous micellar media have emerged as sustainable alternatives to organic solvents for small‐molecule synthesis. This Review discusses the evolution of surfactants for synthesis, their application to cross‐coupling reactions, the benefits for reactivity and sustainability, and the remaining challenges in this rapidly growing field.

Multicomponent Synthesis of Fluorine‐Containing Bioactive Compounds and Drugs

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Multicomponent reactions are robust synthetic tools to assamble complex polyheterocycles and other interesting molecular architectures with potential application in medicinal chemistry, including their fluorine‐containing analogues. Fluorine atoms placed strategically into bioactive molecules often enhance essential pharmacokinetic parameters like ...
