Development of High‐Performance Multilayer Monochromators

open access: yesAdvanced Optical Materials, EarlyView.
Detailed insights into the optical and multilayer design of Double Multilayer Monochromators (DMM) are presented and fully characterized, including key optimization strategies and solutions to fabrication challenges. By integrating in‐house Ion Beam Figuring and a high uniformity multilayer coating process, the developed DMMs achieve high reflectivity,

Boosting the Magnetic Response of a Composite Nanostructure in the Near‐Visible Region with a Fano Resonance

open access: yesAdvanced Photonics Research, EarlyView.
Optical simulations of composite plasmonic split‐ring resonators show that a magnetic response can be obtained at wavelengths near the visible regime. The response is further increased by extending the geometry and enabling a Fano resonance through the coupling of magnetic dipoles.

Engineering of Double Absorber Organic‐Perovskite Solar Cells for >34% Efficiency with V2O5 as Back Surface Field Layer

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates high‐efficiency double perovskite active layer (DPAL) structures using MAPbI3 and MASnI3 to surpass the Shockley‐Queisser limit in single‐junction perovskite solar cells. SCAPS‐1D simulations show that the V2O5‐assisted DPAL device achieves 34.14% power conversion efficiency with improved JSC, VOC, and FF.

In Situ Photopolymerization of Smectic B Liquid‐Crystalline Electrolytes from Mesogenic Phosphate–Diacrylate/Ionic Liquid Complexes for High‐Performance Soft Ionic Actuators

open access: yesAdvanced Robotics Research, EarlyView.
A flexible liquid‐crystalline electrolyte membrane via in situ photopolymerization of a phosphate‐functionalized mesogen, ionic liquid, and diacrylate monomer is developed. The resulting smectic B (SmB)‐phase structure enables 2D ion transport with high conductivity (10−4 S cm−1).

Electrochemical Trifluoromethylchlorosulfonylation of Alkenes via Copper‐Mediated SO2Cl Radical Transfer

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
This article reports an electrosynthetic method for vicinal trifluoromethylchlorosulfonylation of alkenes using [Cu(MeCN)4]PF6 and triethylamine, without elaborate ligands. The reaction efficiently adds CF3 and SO2Cl across diverse unactivated alkenes with broad functional group tolerance.

Engineering of an Ancestral McbA with Enhanced Domain Mobility Extends Biocatalytic Amide Synthesis Scope

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
We show how engineered ancestral amide bond synthetases (ABSs) together with cofactor recycling using a single polyphosphate kinase paves the way for chemoenzymatic synthesis of pharmacophores. The figure illustrates how ancestral ABS has a more flexible C‐terminal domain, which is associated with enhanced catalytic performance and expanded amine scope.

Domino Synthesis of Functionalized Cyclic Acetals From Organic Carbonates

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Cyclic carbonates equipped with acrylic functional groups are shown to undergo a domino process in the presence of a suitable alkoxide to deliver novel types of decorated cyclic acetals. The developed protocol combines practical conditions and a wide scope and features a new reactivity modus for these carbon dioxide‐derived heterocyclic precursors.
