Thermoluminescence properties of pure AlO-ceramic discs doped with some oxides of alkali metals and B were investigated. Two groups of samples were studied: one with a low concentration of B and alkali oxides and the other with higher concentration. The first group shows a relatively higher ...
The particle size of clay minerals is <2microns which can be present in form of plastic in presence of water and solidified when dried. The small size and their distinctive crystal structure make clay minerals very special with their unique properties including high cation exchange capacity, ...
This paper reported the effect of silica fume and sodium silicate nature on the hardened properties, including compressive strength, hydration product and microstructure of alkali-activated municipal solid waste incinerator fly ash. In addition to characterising the property of municipal fly ash, the ...
Geometric Effects in Olefinic Cation−π Interactions with Alkali Metals: A Computational Study Although cation−π interactions commonly involve aromatic or heteroaromatic rings as the source of π-electrons, isolated and nonconjugated olefins are equally effective donors of π-electron density. Previou...
When compared with raw sludge, sludge biochar has minimum pathogens and odor, and is capable of concentrating heavy metals4 (except mercury and cadmium). Studies comparing sludge biochar with raw sludge revealed that the soil properties were improved after applying sludge biochar to the soil as ...
Municipal solid waste incineration (MSWI) fly ash treated with toxicity metals holds enormous potential for constructure use to economize on resources and protect environment. To reach the goal, this study investigated the effects of sintering conditions on leaching characteristic of heavy metals for MSW...
Water scarcity has widely affected agricultural production and food security, particularly in arid regions. There is little information available on the co
The present invention is directed to calcium phosphates in granular form having an X-ray diffraction pattern characteristic of hydroxyapatite in which a portion of the anions of the crystal lattice are substituted with carbonate anions and which have good compressibility and flow properties in direct ...
The results indicated the both torrefactions improved the fuel properties of CSD, including the lower volatiles content, higher carbon content and HHV. The WT showed higher removals of organics and alkali metals, while DT retained more carbon and ash. The SEM, FTIR and XRD analyses indicated ...
Characteristic features of emergency heat removal in reactors with eutectic lead-bismuth and lead coolants are studied. The properties of the eutectic lead-bismuth and lead are different from those of water and gas coolants as well as sodium and other alkali metals. The thermal conductivity of ...
