Separation of metal carbonyls by forming a cobalt complex salt that is insoluble in liquid nickel and iron carbonylFRYSINGER GALEN ROYERBEUTNER HEINZ PAUL
These alloys are composed principally of nickel and iron with small percentages of other metals, and the lowest possible amount of carbon. By the use of this alloy the speed of signalling by long-distance submarine cables has been raised from a maximum of 3oo letters per minute for that ...
. The grain size of the reduced sponge iron was in a wide range of 0.02–30.50 µm2, as quantified using electron backscatter diffraction (see Supplementary Fig. 1). Low-angle grain boundaries (rotation angle <15°, composed of dislocation arrays) constituted the major type of planar...
Routes to nano-phase nickel in the forms of highly porous sponges and dense films have been developed. Nickel acetate and nitrate were mixed with triethanolamine and methanol, and evaporated to a concentrated liquid. Heat-treatment at 10... G Westin,A Pohl,sa Ekstrand,... 被引量: 0发表:...
E.Scientists believe that most of the iron and nickel found in Earth's core came from iron meteorites scattered into space when the interior of an ancient planet broke apart. F.A variety of evidence leads to the conclusion that Earth's inner core is solid and composed primarily of metals,...
While the mining industry narrowly defines base metals as non-ferrous metals excluding precious metals, the broader definition used by US Customs and Borders Protection includes commodities likeAluminum,Copper,Iron,Lead,Molybdenum,Nickel,Steel,Tin, andZinc. ...
(where natural gas is treated with steam in the presence of a catalyst, such as nickel), produce greenhouse gases (called “gray hydrogen”) that will need to be captured or offset in the future. If the carbon produced in these processes is captured and stored, the resulting hydrogen is ...
Many lithium-ion batteries now use a polymer gel or membrane, although some still use a liquid electrolyte. Some designs, such as those in the first and second generations of the Tesla Powerwall, use lithium combined with nickel, manganese, and cobalt (so-calledNMC batteries) in theirconstructi...
To confirm that clade 1 is composed of bilirubin reductase enzymes, we performed experiments to investigate the functional impact of the D166 and R167 residues on the enzyme activity. This included mutating the residues in question to D166A and R167A and heterologously expressing the mutated protei...
irritation. When administered in powdered form to rats, it has been linked to the development of lymphosarcoma and fibrosarcoma. However, there is no evidence suggesting that titanium is carcinogenic to humans. Additionally, research has not demonstrated any harmful effects of titanium dioxide on the...
