Detecting the factors associated with financial decision-making is an unresolved challenge when trying to predict digital financial behavior. This paper reports experimental results on both neuropsychological and neuronal correlates of risk-taking and betrayal aversion among 121 healthy participants (X=21.7; SD = 2.

About one-fifth of people in industrialised countries are tattooed, potentially putting them at risk of exposure to possible carcinogenic or otherwise harmful substances. This study aims to determine the exposure to soluble tattoo ink ingredients and their excretion within 24 h after tattooing. In this clinical study, 24 subjects were tattooed with black or red tattoo ink to which the 3 tracer substances, potassium iodide, 4-aminobenzoic acid (PABA) and 2-phenoxyethanol (PEtOH), had been added to mimic known substances found in tattoo inks.

Photoelectrochemical (PEC) water splitting for hydrogen production is a promising technology for sustainable energy generation. In this work, we introduce Nd sites boost the PEC performance of FeO photoanodes through a precise gas-phase cation exchange process, which substitutes surface Fe atoms with Nd. The incorporation of Nd significantly enhances charge transfer properties, increases carrier concentration, and reduces internal resistance, leading to a substantial increase in photocurrent density from 0.

Hydrogen plays a key role in maximizing the benefits of renewable energy, and the widespread adoption of water electrolyzers and fuel cells, which convert the chemical energy of hydrogen and electrical energy into each other, is strongly desired. Electrocatalysts used in these devices, typically in the form of nanoparticles, are crucial components because they significantly affect cell performance, but their raw materials rely on limited resources. In catalyst research, electrochemical experimental studies using model catalysts, such as single-crystal electrodes, have provided valuable information on reaction and degradation mechanisms, as well as catalyst development strategies aimed at overcoming the trade-off between activity and durability, across spatial scales ranging from the atomic to the nanoscale.

This study investigated how contraction frequency impacts the mechano-energetics of cardiac muscle performing mechanical work. Left-ventricular trabeculae were isolated from rat hearts and mounted in our work-loop calorimeter to assess their function at physiological temperature (37°C) across three stimulation frequencies, 2 Hz, 3.5 Hz and 5 Hz, in a randomised sequence.
