Recent advances in the study of mercury methylation in aquatic systems

FACETS, 2017
With increasing input of neurotoxic mercury to environments as a result of anthropogenic activity, it has become imperative to examine how mercury may enter biotic systems through its methylation to bioavailable forms in aquatic environments.

Use of mercury isotopes to quantify sources of human inorganic mercury exposure and metabolic processes in the human body

Environment International, 2021
The pathways of human mercury (Hg) exposure are complex and accurate understanding of relative contributions from different pathways are crucial for risk assessment and risk control.

New Isotopes of Mercury [PDF]

Nature, 1932
IN the course of some tests with very sensitive Schumann plates supplied by Messrs. Adam Hilger, I have obtained mass-spectra of mercury of an intensity greater than any previously photographed. On the best of these there are unmistakable traces of two new lines 197 and 203. The first is certainly due to a new isotope.

Mercury stable isotopes suggest reduced foraging depth in oxygen minimum zones for blue sharks

, 2022
International audienceOxygen minimum zones (OMZs) are currently expanding across the global ocean due to climate change, leading to a compression of usable habitat for several marine species.

Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

Advanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

High-density element concentrations in fish from subtidal to hadal zones of the Pacific Ocean

Heliyon, 2018
Anthropogenic use of high density, toxic elements results in marine pollution which is bio-accumulating throughout marine food webs. While there have been several studies in various locations analyzing such elements in fish, few have investigated ...

Tailored D‐π Conjugation Boosts Piezocatalytic CO2 Reduction in a Platinum(II)‐Acetylide Framework

Advanced Science, EarlyView.
The highly conjugated metalII‐acetylide framework demonstrates efficient ultrasound‐driven conversion of CO2 to CO. The piezoelectric field generated by ultrasound facilitates electron transfer from the tetraphenylene π‐column to the MII‐bis(acetylide) moiety, enabling CO2 activation. Compared to PdII‐ and NiII‐based analogues, the stronger d–π orbital
