Adaptive Method for Quantitative Estimation of Glucose and Fructose Concentrations in Aqueous Solutions Based on Infrared Nanoantenna Optics

open access: yesSensors, 2019
In life science and health research one observes a continuous need for new concepts and methods to detect and quantify the presence and concentration of certain biomolecules—preferably even in vivo or aqueous solutions. One prominent example, among

Is support for authoritarian rule contagious? Evidence from field and survey experiments

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract The increasing popularity of strongman rule in democratic societies underscores the need to explore how authoritarian regime preferences might spread socially. We assess the role of social influence on support for leaders with authoritarian inclinations through preregistered field and survey experiments in the Norwegian Armed Forces. The field

PtRu Clusters Enable Efficient Proton Transfer and Rapid Hydrogen Evolution

open access: yesCarbon Neutralization, Volume 5, Issue 4, July 2026.
PtRu clusters on hollow mesoporous carbon spheres exhibit superior HER activity via strong electronic coupling. Ru sites enrich hydronium ions, creating a microenvironment for rapid H* directional transfer. Ru acts as the dominant center with near‐neutral binding energy, while Pt modulates the electronic structure for optimal kinetics.

Concerted Proton and Electron Transfer in Heterogeneous Electrocatalytic CO2 Reduction

open access: yesAngewandte Chemie, Volume 138, Issue 23, 1 June 2026.
Concerted proton‐electron transfer (CPET) enables CO2‐to‐CO conversion with significantly reduced energy cost compared to cation‐stabilized pathways. Under controlled mass transport of proton donors, CPET dominates at modest potentials. At higher overpotentials, a cation‐stabilized pathway is found to dominate.

Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3− coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous interface synergistic ...
