(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 ...
. 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...
Iron is also the fourth most common element in Earth's crust by weight and much of Earth's core is thought to be composed of iron. Besides being commonly found on Earth, it is abundant in the sun and stars, according to the Los Alamos National Laboratory. Iron is crucial to the ...
Waste activated sludge (WAS), also known as secondary sludge, is generated during the biological treatment of wastewater and is primarily composed of microbial cells, which are polymeric organic molecules. The total solids content in secondary sludge varies from 0.8% to 1.2%, depending on the ...
Laboratory experiments, however, suggest that a highly pressurized iron-nickel alloy might be too dense and that minor amounts of such elements such as silicon, sulfur, carbon, or oxygen may also be present to lighten the core material. Support for the theory that the core is composed of ...
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...
Hypoxia-inducible expression of typical hypoxia-responsive genes such as VEGF and erythropoietin (Epo) has well-known pharmacological features. For instance, it is mimicked in normoxic cells by transition metals such as cobalt, nickel, and manganese, and by the iron chelator DFO, but not by pois...
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. ...
It's not news that there was once water on Mars. In fact, there still is, as Mars is one of theplanets with polar ice caps, which are largely composed of frozen water. However, it has long been believed that liquid water vanished from Mars at least two billion years ago. A recent ...
