Study on Mercury Exposure and Different Approaches for the Management of Mercury Toxicity

open access: yesProceedings
Mercury (Hg) is a highly toxic heavy metal that causes significant risks to human health and the environment. This study explores the sources and routes of mercury exposure to humans, its toxicological effects, and the various methods of phytoremediation

High‐Performance Electrocatalysts of Potassium Lactate Oxidation for Hydrogen and Solid Potassium Acetate Production

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Potassium lactate, produced from polylactic acid plastic waste, is oxidized to potassium acetate on an anode using Ni(Co)OOH as the electrocatalyst, while hydrogen is simultaneously generated at the cathode, through a highly efficient industrial‐scale electrolysis system.

Early Parkes Observations of Planets and Cosmic Radio Sources [PDF]

open access: yes, 2012
We discuss early Parkes observations of the radio emission from the planets Mercury, Venus, Mars, Saturn, and Uranus. The sensitive Parkes 11 cm system was used to detect a surprisingly high observed nighttime temperature on Mercury, the first, but ...

Engineering Flow‐Through Hollow Fiber Gas‐Diffusion Electrodes for Unlocking High‐Rate Gas‐Phase Electrochemical Conversion

open access: yesAdvanced Materials, EarlyView.
Advancing gas‐phase electrolysis toward industrial‐scale applications requires not only the development of advanced electrocatalysts but also the design of the electrodes to optimize gas‐electrode‐electrolyte interfaces and facilitate efficient mass transport, thereby reinforcing gas win the electrons to promote reaction kinetics and suppress side ...

A trapped mercury 199 ion frequency standard [PDF]

open access: yes, 1982
Mercury 199 ions confined in an RF quadrupole trap and optically pumped by mercury 202 ion resonance light are investigated as the basis for a high performance frequency standard with commercial possibilities.

Water Oxidation to Hydrogen Peroxide Over a Super‐Aerophilic Graphite Catalyst

open access: yesAdvanced Materials, EarlyView.
Design of super‐aerophilic graphite catalyst capable of trapping in situ produced oxygen gas on its surface under the electrolyte environment. By so doing, it is able to moderate intermediate species binding, which is critical to enabling the two‐electron water oxidation reaction to hydrogen peroxide.

Transient Phenomena of Mercury [PDF]

open access: yesarXiv
The similarity of Mercury to the Moon raises the question on mercurian analogues of lunar transient phenomena. However, since the mid-1960s, this topic has remained out of attention. Nevertheless, the discoveries of the 21st century and the BepiColombo mission give hope for the registration of Mercury transient phenomena.
