Light Up a Nanocluster

Aggregate, Volume 7, Issue 1, January 2026.
Atomically precise metal nanoclusters are ultrasmall aggregates of metal atoms with finely tunable structures. They exhibit broad PL across visible to NIR wavelengths by tuning size, structure, and composition. The review addresses fundamental emission mechanisms and structure–property correlations, evaluating enhancement strategies (ligand ...

Enantioselective Oxidative Spirocyclization of Biaryl Hydroxy Carboxylic Acids: Enantioselective Synthesis of (–)‐Arnottin II

Chemistry – An Asian Journal, Volume 21, Issue 1, January 2026.
The first catalytic and metal‐free enantioselective synthesis of (–)‐arnottin II is reported. A one‐pot hydrolysis/oxidative spirolactonization sequence, catalyzed by a chiral hypervalent iodine(I/III) complex under phosphate‐buffered conditions, establishes efficient control of the unstable biaryl hydroxy carboxylic acid (BHCA) intermediate, to afford

Understanding the Role of pH Regulation and Neutralizing Agents in Organic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, Volume 123, Issue 1, Page 116-133, January 2026.
We show that pH and neutralization strategy strongly influence the growth, pellet morphology, and organic acid production of Aspergillus oryzae. Acidic and alkaline conditions lead to hairy, dispersed pellets, while near‐neutral environments favour compact pellet formation.

Bioreduction of β‐ketosulfides Using Deep Eutectic Solvents as Cosolvents

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
A set of β‐ketosulfides has been selectively reduced to optically active β‐hydroxysulfides employing KREDs as biocatalysts in the presence of Deep Eutectic Solvents. By appropriately selecting both the biocatalyst and the reaction medium, both alcohol enantiomers can be obtained in high yields and optical purities.

Remote Conformational Control of a Chloride‐Binding Site

ChemistryEurope, Volume 4, Issue 1, January 2026.
Chloride‐binding foldamers have been developed that have stereogenic C‐ and N‐terminal groups separated by a helical α‐aminoisobutyric acid (Aib) body. Chloride affinity is sensitive to the sense and strength of screw‐sense induction by each N‐terminal residue.
