Altering the Coordination of Iron Porphyrins by Ionic Liquid Nanodomains in Mixed Solvent Systems [PDF]

, 2017
The solvent environment around iron porphyrin complexes was examined using mixed molecular/RTIL (room temperature ionic liquid) solutions. The formation of nanodomains in these solutions provides different solvation environments for substrates that could

Biomass Electrorefining: Electrical‐to‐Chemical Energy Relay Systems for Hydrogen‐Chemical Coproduction via Multi‐Reaction Electrocatalytic Cascades

Carbon Neutralization, Volume 5, Issue 1, January 2026.
This graphical abstract illustrates an integrated electrocatalytic refining system designed for sustainable chemical and fuel production. At its core, the Biomass Oxidation Reaction (BOR) replaces conventional water oxidation at the anode. It is coupled with various cathodic reactions, such as the Hydrogen Evolution Reaction (HER), CO2 Reduction (CO2RR)

A Search for Fluctuation-Dissipation Theorem Violations in Spin-Glasses from Susceptibility Data

, 1999
We propose an indirect way of studying the fluctuation-dissipation relation in spin-glasses that only uses available susceptibility data. It is based on a dynamic extension of the Parisi-Toulouse approximation and a Curie-Weiss treatment of the average ...

Over 75% incident-photon-to-current efficiency without solid electrodes. [PDF]

, 2016
The efficiency of photoelectrochemical reactions is conventionally defined in terms of the ratio between the current responses arising from the collection of carriers at electrical contacts and the incident photon flux at a given wavelength, i.e.
