2017-2-19For convenience of comparison the volumes of the oxides are all calculated per two atoms of an element combined with oxygen. For example, the density of Al 2 O 3 = 40, weight Al 2 O 3 = 102, volume Al 2 O 3 = 255. Whence, knowing the volume of aluminium to be 11, it is at once seen that in the formation of aluminium oxide, 22 volumes of it
Ionic liquids (ILs) were studied as solvents for electrochemical reactions with the intent to devise metallurgical processes for Al, Mg and Ti that are less energy intensive and operate at lower temperatures than current industrial practice. Tetra-alkyl phosphonium ILs are on the low end of the IL cost spectrum and are regarded as understudied compared with imidazolium and
2019-5-25This Review describes recent advances in the design, synthesis, reactivity, selectivity, structural, and electronic properties of the catalysts for reforming of a variety of oxygenates (e.g., from simple monoalcohols to higher polyols, then to sugars, phenols, and finally complicated mixtures like bio-oil).

The results of Ito et al are of special interest. They showed that ammonia treatment of dense silicon oxides–thermally grown on silicon–increased the refractive index from 1.45 to 1.65. They used anhydrous ammonia to carry out the treatment at 1200C for 1hr.
In 2010, Oman's first chromite ore concentration plant at Wadi Mahram was inaugurated by Gulf Mining. The plant is said to have a capacity of 180,000 t/yr. Al Tamman and Indsil Group of India had plans to build a $70 million chromite smelter at the Sohar Industrial Estate in the same year.

2016-2-29[1] Chemistry, like every other science, is at once a means and an end. It is a means of attaining certain practical results. Thus, by its assistance, the obtaining of matter in its various forms is facilitated; it shows new possibilities of availing ourselves of the forces of nature, indicates the methods of preparing many substances, points out their properties, c.
At hydrogen concentrations of 7-8%, all the sulfur present in the gases passed into the absorbent. The maximum sulfur capacity of different oxide sizes was found at 400 C. The capacity was 20.5% for 0.15-0.25-mm fractions, 18.5% for the waste oxide, and
The increase of adsorption capacity with increasing Fe 2 O 3 /C ratio in the sludge indicates that under these experimental conditions, the process of lead ion adsorption occurs more strongly on the hematite phase than on the carbon phase ( Lopez-Delgado et al., 1998 ).

A large negative thermal expansion (NTE) was discovered in simple cubic scandium trifluoride (ScF3) over a wide range of temperatures. The underlying mechanism has been explained by Li et al. [1] in terms of the vibration mode with the transverse motion of F atoms to their bond direction which behaves as quantum quartic oscillator.
The construction of the Medupi Power Station will provide much needed new base load capacity, which will be commissioned in stages from 2012 onwards. Ultimately, Eskom plans to double its capacity to 80 000MW by 2026. This will ensure that the country‟s economic development objectives remain on track and that security of supply is restored.
