Thermoelectric Generator Based on Kesterite (Cu2ZnSnS4) Synthesized via Sol–Gel Method

The need for sustainable and cost-effective thermoelectric materials has brought attention to earth-abundant and mineral compounds, like Cu2ZnSnS4 (CZTS). In this work, CZTS nanoparticles (NPs) were synthesized via the sol–gel method using environmentally friendly solvents based on water and ethanol mixtures. The resulting CZTS NPs were then processed into inks through ball milling to produce a thin-film thermoelectric generator (TEG). Structural and microstructural properties were investigat...

Poly(DL-Phenylalanine) modified biosynthesized ZnO nanoparticles composite carbon paste electrode for the determination of melatonin

A new electrochemical sensor was fabricated for the selective analysis of melatonin (MEL). In this work, a novel sensing platform combining biosynthesized zinc oxide nanoparticles (ZnONPs) with electropolymerized DL-phenylalanine (DLP) was developed. The electrode was fabricated by modifying the surface of bare carbon paste electrode with biosynthesized Zinc oxide nanoparticles (BZnONPs/CPE) and further coated with an electrochemically polymerized DL-phenylalanine film (P(DLP)MZnONPs/CPE). Th...

Prenatal mercury exposure and child neurodevelopment outcomes at 18 months: Results from the Mediterranean PHIME cohort

Introduction Neurotoxicity due to acute prenatal exposure to high-dose of mercury (Hg) is well documented. However, the effect of prenatal exposure to low Hg levels on child neurodevelopment and the question about “safety” of fish-eating during pregnancy remain controversial. International comparisons of Hg concentrations in mother-child biological samples and neurodevelopmental scores embedded in birth cohort studies may provide useful evidence to explore this issue. Materials and methods ...
