The Activation of Hydrogén by Excited Mercury Atoms [PDF]

open access: green, 1925
That mercury atoms excited by absorption of the line 2537Å are able to activate various kinds of atoms by collisions of the second kind has been shown in several different ways.

Estimating chromium concentration in arable soil based on the optimal principal components by hyperspectral data

open access: yesEcological Indicators, 2021
The heavy metal pollution in arable soil poses a significant threat to human health. Thus, it is of great significance to investigate the contamination of heavy metal elements in the soil.

Effects and mechanism of igneous rock on selenium in the tropical soil-rice system in Hainan Province, South China

open access: yesChina Geology, 2022
To illuminate the migration and transformation of selenium (Se) in the igneous rock-soil-rice system, 285 pairs of rhizosphere soil and rice samples were collected from the granitoid and basalt areas in Hainan Province, South China. The contents of Se in

Boulders on Mercury [PDF]

open access: yesIcarus, 2021
Boulders on the surfaces of planets, satellites and small bodies, as well as their geological associations, provide important information about surface processes. We analyzed all available images of the surface of Mercury that have sufficient resolution and quality to detect boulders, and we mapped all the boulders observed.

High mercury emission (both forms: Hg0 and Hg2+) from the wet scrubber in a full-scale lignite-fired power plant [PDF]

open access: yes, 2020
The paper describes and discusses the results of research on mercury behaviour, especially its high emission, in both forms: elemental (Hg-0) and oxidised (Hg2+) from the wet flue gas desulphurisation scrubber (WFGD) in a lignite-fired power plant ...

Application of Ce for scavenging Cu impurities in A356 Al alloys

open access: yesEuropean Journal of Materials, 2022
Secondary (recycled) Al is increasingly used in castings due to its lower cost and carbon footprint relative to primary Al. However, the presence of certain impurity elements in secondary Al degrades its properties, often requiring dilution or ...

Effect of flue gas purification facilities of coal-fired power plant on mercury emission

open access: yesEnergy Reports, 2021
The types and concentration of mercury in flue gas of nine coal-fired units were measured by OH method and the mercury content in desulfuration wastewater, slag, fly ash and gypsum were also measured.

The Origin of Mercury [PDF]

open access: yesSpace Science Reviews, 2007
Mercury’s unusually high mean density has always been attributed to special circumstances that occurred during the formation of the planet or shortly thereafter, and due to the planet’s close proximity to the Sun. The nature of these special circumstances is still being debated and several scenarios, all proposed more than 20 years ago, have been ...
