Electrolyte Anions Suppress Hydrogen Generation in Electrochemical CO Reduction on Cu.

In this study, we employed EC-MS to elucidate the role of halide anions in electrochemical CO2 and CO reduction. We found that the undesired hydrogen evolution reaction (HER) was significantly suppressed by the anion used. Specifically, the rates of H2 production decreased in the order KF > KCl > KI, meaning that I- most strongly suppressed HER.

Leveraging electrochemical double layer structure to rationally control electrolysis.

This perspective delves into the electrochemical microenvironment, uncovering entropic effects in CO reduction, revealing neutral molecule electrosorption under polarization, highlighting challenges in the classical double layer model, and proposing research approaches for future interface studies.

Workshop on hastened death as "space for an appreciative discussion": A qualitative study.

Aim: To evaluate the suitability of a drama-based workshop as a method for ethical deliberation.

Background: Nurses worldwide are inadequately prepared to care for people who desire hastened death, which can lead to ethical and moral dilemmas. To address this problem, we developed a drama-based ethical deliberation workshop to assist nurses in these situations.

Electrochemical Synthesis of Sound: Hearing the Electrochemical Double Layer.

Electrochemical double layers (EDLs) govern the operation of batteries, fuel cells, electrochemical sensors, and electrolyzers. However, their invisible nature makes their properties and function difficult to conceptualize, creating an impediment to the broader understanding of double-layer function required for future technologies in energy storage and chemical synthesis. To render the behavior of electrochemical interfaces more intuitive, we made the rearrangement of interfacial components audible by employing the EDL as a variable element in a relaxation oscillator circuit.

Mind the Interface: The Role of Adsorption in Electrocatalysis.

In the field of electrocatalysis, significant emphasis has been placed on developing electrode materials to enable critical energy storage reactions and sustainable chemical synthesis. However, the electrode is just one part of a complex interfacial environment that controls substrate adsorption and reactivity. In the presence of a liquid electrolyte and an electrochemical interface, adsorption processes behave substantially differently than those in the gas phase.
