Sedimentary records of mercury stable isotopes in Lake Michigan
Elementa: Science of the Anthropocene, 2016 Mercury (Hg) concentrations and Hg isotopic composition were investigated in three sediment cores in Lake Michigan (LM). Two cores were collected from Green Bay, a region heavily impacted by Hg contamination and one core from an offshore region of LM ...

Discovery of the Mercury Isotopes
, 2009 Forty mercury isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented.

High-spin states in 183Hg and shape coexistence in the odd-mass mercury isotopes
, 1995 High-spin states in Hg have been identified using the reaction Gd(S,4n). Three prolate-deformed rotational bands associated with the 1 2[521], 7 2[514] and mixed i neutron orbitals are observed, while the existence of an oblate 13 2 bandhead is inferred,

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Metal‐CO2 batteries have recently emerged as an intriguing class of energy storage and conversion devices that simultaneously utilize and manage carbon dioxide. Originating from studies of CO2 contamination in metal‐air batteries, these systems have evolved into a distinct research direction, offering insights into CO2 electrochemistry and its

Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production
Carbon Energy, EarlyView.Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐

Enhanced four-wave mixing in mercury isotopes, prepared by stark-chirped rapid adiabatic passage
, 2020 We demonstrate significant enhancement of four-wave mixing in coherently driven mercury isotopes to generate vacuum-ultraviolet radiation at 125 nm. The enhancement is accomplished by preparation of the mercury atoms in a state of maximum coherence, i.e.

Mercury isotopic evidence for the importance of particles as a source of mercury to marine organisms
Proceedings of the National Academy of Sciences, 2022 The origin of methylmercury in pelagic fish remains unclear, with many unanswered questions regarding the production and degradation of this neurotoxin in the water column. We used mercury (Hg) stable isotope ratios of marine particles and biota to elucidate the cycling of methylmercury prior to incorporation into the marine food web.

Carbon Energy, EarlyView.Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...
