Large‐Area Metallic Nanohelices for Engineering Optical Chirality

Small, EarlyView.
By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...

f‐Block Element‐Based MOF Thin Films: A Platform for Luminescence, Sensing, and Energy Applications

Small, EarlyView.
f‐Block element–based metal–organic framework (f‐MOF) thin films offer exceptional potential for luminescent, sensing, and energy‐related applications. This review surveys recent progress in their synthesis, characterization, and functional implementation, emphasizing the diversity of available thin‐film fabrication strategies. The convergence of these

Benzochromanone and Benzochromene Natural Products: Synthetic Strategies and Total Syntheses

The Chemical Record, EarlyView.
This work outlines synthetic strategies for natural products with benzochromanone and benzochromene cores. Key achievements include total syntheses of xanthones, blennolide C, gonytolide C, and teretifolione B. Spirochromanone intermediates, benzyne–furan Diels–Alder reactions, and enzymatic resolution enabled efficient and enantioselective access to ...

Enantioselective Determination of Chiral Fungicides in Food Samples Using Automated Dispersive Microextraction Coupled With UHPLC–MS/MS

Food Frontiers, Volume 7, Issue 2, March 2026.
The use of fatty acids and bio‐derived solvents eliminates the need for toxic solvents and, when combined with automated workstations, enables parallel sample processing, thereby improving extraction efficiency and reducing human error. ABSTRACT An enantioselective analytical method based on automated dispersive liquid–liquid microextraction (DLLME ...
