Thorium as a nuclear fuel. Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is 'fertile' and upon absorbing a neutron will transmute to uranium-233 (U-233) a, which is an excellent fissile fuel material b. In this regard it is similar to uranium-238 (which transmutes to plutonium ...

The widespread, intentional and increasingly frequent chemical emplacement in the troposphere has gone unidentified and unremarked in the scientific literature for years.

Coal ash, a waste product, generated from the combustion of coal, consists of fly ash, bottom ash, boiler slag, and flue gas desulfurization material. Fly ash, which is the main component of coal ash, is composed of spherical particulate matter with diameters that range from 0.1 μm to >100 μm.

thallium, thorium, vanadium and uranium. Although seemingly unacknowledged in publicly accessible reports and in scientific literature as a potential material for geoengineering, coal fly ash is one major global waste product stream with the appropriate grain-size distribution for aerosolized tropospheric spraying that is readily …

Thallium concentrations of up to 46 μg g −1 (ash basis) have been detected in high-As, high-S lithotypes in the Pond Creek coal bed in Pike and Martin counties, eastern Kentucky [48]. The high concentrations could be attributable to Tl–As substitution in pyrite, which is supported by the correlation of Tl and As with pyritic sulphur.

Thallium is a heavy metallic element that exists in the environment mainly combined with other elements (primarily oxygen, sulfur, and the halogens) in inorganic compounds. ... Davison et al. (1974) reported concentrations of thallium on airborne fly ash emitted from a coal-burning power plant ranging from 29 to 76 µg/g, the thallium ...

Single-crystal X-ray diffraction data were collected on a Bruker APEXII CCD diffractometer with the use of the graphite-monochromatized MoK α radiation (λ=0.71073 Å). A data collection strategy consisting of φ and ω scans was devised using COSMO in APEXII [7].The data frames were 0.5° in width and taken at a detector distance of 60 mm …

Volcanic ash contains thallium (Tl), which is highly toxic to the biosphere. The aim of this study was to determine the Tl concentration in fractions of volcanic ash samples originating from the Eyjafjallajökull volcano. A sequential extraction scheme allowed for a study of element migration in the environment. Differential pulse anodic ...

The thallium contents and ash yield of the combustible blends (CMA–CMD) can be considered statistically the same with an average Tl concentration of 0.76 μg g −1, which represents 1.16 μg g −1 if it is referred to the ashes. Worthy of note is that the total ash yield of the combustible material has values as high as 65% because of the ...

Prolonged contact time between the ash and exhaust fumes leads to a notable concentration of thallium in fly ash, which is 2 to 10 times higher compared to the state prior to combustion (Cvjetko et al. 2010; Finkelman 1999). Global resources of thallium in coal amount to 630,000 t.
