A Comparative Study of the Influence of Water and Temperature on the Racemization of Five‐ and Six‐Membered l‐Alanine‐Derived Imides

Chirality, Volume 38, Issue 8, August 2026.
Racemization of chiral imides in dimethylformamide is shown to increase with increasing water content and temperature. The six‐membered imide ring system is more stable than the five‐membered analogue, with slower racemization under identical conditions and an absence of competing side reactions.

1‐Aryl‐6,7‐Dimethoxy‐3,4‐Dihydroisoquinoline‐2(1H)‐Sulfonamides as hCA XII Selective Inhibitors: Experimental and Theoretical Studies to Interrogate the Isoform Selectivity

ChemMedChem, Volume 21, Issue 14, 29 July 2026.
Experimental and theoretical studies have disclosed the more relevant structural requirements for effective inhibition and an impressing selectivity toward tumor‐expressed hCA XII isoform over hCA II. Human carbonic anhydrase XII (hCA XII) represents an important pharmacological target for different types of cancer.

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...

Planar Chiral Nanoantenna for Excitation‐Chirality‐Controlled Hot Spot Modulation and Emitter‐Coupled Circularly Polarized Emission

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
A planar chiral plasmonic nanoantenna is shown to translate the changing handedness of circularly polarized excitation into deterministic switching of a nanoscale hot spot with maximal dissymmetry and complete modulation depth. Coupling an achiral quantum emitter to the nanogap simultaneously enables circularly polarized emission of near‐maximal purity,

Enhanced Enantioselective Optical Trapping Enabled by Longitudinal Mie Resonances in Silicon Nanodisks

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Longitudinal Mie resonances in silicon nanodisks, excited by an azimuthally–radially polarized beam, generate strong optical chirality gradients with minimal achiral background. Magnetic quadrupole modes enable selective enantiomer trapping, achieving predicted selectivities over 100 for |κ|≥0.03 $\vert \kappa \vert \ge 0.03$ and robust performance ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
