Brushes come in a vast array of types, ranging from fine artist’s brushes to large brushes several feet in diameter used for cleaning floors and polishing metals. The shape and design of a brush are tailored to suit different purposes....
Looking at analysis results of metallurgical route solar silicon in a more general and statistical way, one can distinguish between dopants and metals versus nonmetallic impurities.Figure 2.41plots the analysis data of six different silicon suppliers between the years 2006 and early 2011 so that the ...
Steels • Superalloys – Iron-based – Nickel-based – Cobalt-based • Non-ferrous metals – Aluminum and its alloys – Copper and its alloys – Magnesium and its alloys – Nickel and its alloys – Titanium and its alloys – Zinc and its alloys – Lead & Tin – Refractory metals – ...
From a metallurgical perspective, gold ores can be broadly subdivided into free-milling and refractory types. The former are relatively easy to treat and give good gold recoveries (> about 90 percent), whereas the latter are difficult to treat and give gold recoveries of less than 90 percent,...
spectra with energy level diagrams for light element (e.g. Na and Mg) is relatively straightforward, the same is not applicable to heavier elements (e.g. Ca or transition metals). For instance, the number of lines in neutal atoms and singly changed ion are Li(30), Mg(173), Ca(662)...

Biochar, a green material that possesses high catalytic potential due to its persistent free radicals (PFRs), has attracted increasing attention in the removal of refractory pollutants from water. The influences of biomass types (bamboo, corn stalk, and pig manure) and its compositions (metals and...

The origins of such effects are then qualitatively discussed from the viewpoints of lattice-strain energies and electronic bonds. Quantification of the interaction between Al and 3d transition metals in fcc, bcc, and intermetallic compounds is illustrated in the thermodyna...
