Functional Ambidexterity of an Ancient Nucleic Acid‐Binding Domain

open access: yesAngewandte Chemie International Edition, Accepted Article.
The helix‐hairpin‐helix (HhH) motif is an ancient and ubiquitous nucleic acid‐binding element that has emerged as a model system for studying the evolution of dsDNA‐binding domains from simple peptides that phase separate with RNA. We analyzed the entire putative evolutionary trajectory of the HhH motif – from a flexible peptide to a folded domain ...

The Effect of Coating Pd/Al2O3 and PdAg/Al2O3 Catalysts with [BMIM][DCA] for the Selective Hydrogenation of 1‐Octyne in 1‐Octene

open access: yesChemCatChem, Volume 15, Issue 1, January 9, 2023., 2023
Catalysts have SKILLS too – the SCILL effect: Whilst all uncoated catalysts showed close to a 100 % conversion of the substrates, the optimised SCILLs (Solid Catalysts with an Ionic Liquid Layer) were able to significantly decrease octene conversion and also improve the 1‐octene gain at high octyne conversions. A 1‐octene gain was achieved with 4 ML of

On Certain Diophantine Equations Involving Lucas Numbers [PDF]

open access: yesarXiv
This paper explores the intricate relationships between Lucas numbers and Diophantine equations, offering significant contributions to the field of number theory. We first establish that the equation regarding Lucas number $L_n = 3x^2$ has a unique solution in positive integers, specifically $(n, x) = (2, 1)$, by analyzing the congruence properties of ...

Selective Conversion of Glycerol to Value‐Added C3 Products: Effect of Catalyst Surface Structure

open access: yesChemCatChem, Volume 15, Issue 2, January 20, 2023., 2023
Challenges in the selective oxidation of glycerol (GLY) to value‐added products like dihydroxyacetone (DHA) and glyceraldehyde (GALD) are addressed by utilizing density functional theory calculations to investigate the structure sensitivity of the reaction mechanism on transition metal surfaces.

Tailored Particle Catalysts for Multistep One‐pot Chemoenzymatic Cascade in Pickering Emulsions

open access: yesChemCatChem, Volume 15, Issue 1, January 9, 2023., 2023
Chemoenzymatic cascades are enabled by combining particle catalysts and enzymes in water and Pickering emulsions in a sequential fashion. The benefit of such multistep one‐pot chemoenzymatic cascades is their high reactivity, selectivity, and recyclability without reaction incompatibility issues.

The PteridoPortal: A publicly accessible collection of over three million records of extant and extinct pteridophytes

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Pteridophytes—vascular land plants that disperse by spores—are a powerful system for studying plant evolution, particularly with respect to the impact of abiotic factors on evolutionary trajectories through deep time. However, our ability to use pteridophytes to investigate such questions—or to capitalize on the ecological and ...
