Solvent‐Controlled Electrochemical Cyclization of Areneazo‐2‐(2‐nitro)propanes to Benzo[c]cinnolines

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Solvent‐mediated redox pathway control enables the first electrochemical cyclization of areneazo‐2‐(2‐nitro)propanes to benzo[c]cinnolines. Mixed solvent systems containing hexafluoroisopropanol (HFIP) and MeOH additives widen the redox potential gaps and stabilize diazonium intermediates via hydrogen bonding, favoring oxidative intramolecular ...

Catch, Release, Repeat: Reversible Protein Capture in Electric Fields Using Antifouling Polymer Brushes

Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
ABSTRACT Capturing proteins is easy since their amphiphilic nature allows them to bind to almost any surface. Because of this, releasing them is challenging since various interactions need to be considered for this. We present a simple method to reversibly adsorb proteins on stabilized electrodes.

Dynamic Plasmonic Metasurface Regulated by Drude‐Like Active Spacers

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
Optical properties of mirror‐coupled plasmonic metasurface are dynamically modulated by controlling intrinsic properties and geometric parameters of Drude‐like active spacers made of transparent conducting oxides and phase‐change materials. The resonance property of a hybrid plasmonic metasurface can be actively regulated by manipulating the ...

Voltammetric Studies of Nitrate Reduction at Boron‐Doped Diamond Thin‐Film Electrodes of Different Microstructure

Electroanalysis, Volume 38, Issue 5, May 2026.
The electrochemical reduction of nitrate at polycrystalline boron‐doped diamond (BDD) electrodes using three different microstructures was studied. The reduction of nitrate proceeded similarly on the three BDD electrode types in terms of onset and peak potentials in 0.1 M Na2SO4.

Losartan API and Nitrosamines Impurities—Stability Profile Investigation Using HPLC, LC‐MS, and In Silico Assessment

Journal of Separation Science, Volume 49, Issue 5, May 2026.
ABSTRACT Nitrosamines are potent genotoxic impurities with well reported mutagenic and carcinogenic effects. Their presence has been detected in several pharmaceutical products among them losartan, an angiotensin II receptor blocker. Considering the risks already reported for these impurities, the present study aimed to investigate the influence of ...
