Robot‐Assisted Measurement of the Critical Micelle Concentration

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

Carbon‐Doped Amorphous Gallium Oxide Forms a Heterojunction With Water to Improve the Electrocatalytic Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

A Novel Heterometallic Ring {Cr5Ni3} and New {Cr6Co2} and {Cr6Zn2} Rings

Chemistry – A European Journal, EarlyView.
A novel heterometallic ring containing five Cr(III) and three Ni(II) centers is reported. It forms an octagon and has a single isomer, as revealed by a combination of magnetic and EPR studies and collision‐induced dissociation mass spectrometry. ABSTRACT A new heterometallic ring, [Me4N][(Me4N)2Cr5Ni3F8(BTFB)16] (BTFB = 3,5‐bis(trifluoromethyl)benzoate)
