The Nature of Pristine Noble Gases in Mantle Plumes. Discusses the nature of pristine noble gases which are important tracers to degassed shallow mantle and a less degassed deep reservoir associated with mant... Trieloff,Mario,Kunz,... - 《Science》 被引量: 319发表: 2000年 On the origin ...
Gas separation also has implications for other fields, such as the production of high-purity oxygen6,7 and nitrogen8,9 for industrial purposes and the purification of noble gases for medical diagnosis, and lasers10,11. Given its importance, research in this area is crucial for advancing ...
Conversion of plastic wastes to valuable carbon resources without using noble metal catalysts or external hydrogen remains a challenging task. Here we report a layered self-pillared zeolite that enables the conversion of polyethylene to gasoline with a r
These concentrations require high pressures of nebula gas in contact with Theia’s magma ocean, especially considering its reduced nature. As described above, the solubility of H2 in silicate magmas is poor but the solubility of H2O is relatively high (Fricker and Reynolds, 1968; Hirschmann et ...
Although the past 70 years have demonstrated the agile nature of both equipment licensors and FCC catalyst manufacturers, today's refiners demand more. As alluded in the text above, the field of zeolite-based olefin maximization additives still has room for improvement – namely in the ability ...
Metals and alloys are among the most technologically important materials for our industrialized societies. They are the most common structural materials us
The noble gases He, Ne and Ar in fluid inclusions from mantle xenoliths at three localities in Northern Victoria Land (Baker Rocks, Greene Point and Handler Ridge), spanning about 300 km, provide new constraints on the nature of the lithospheric mantle beneath the West Antarctic Rift System ...
nasal and mucous membrane inflammation, conjunctival inflammation, respiration disruption, nerve disease, lung irritation, and even death. Thus, monitoring alcohols in the air, because of their flammable nature, is essential in certain working places [6,7]. In addition to chemical and industrial stud...
The Apollo-derived tenet of an anhydrous Moon has been contested following measurement of water in several lunar samples that require water to be present in the lunar interior. However, significant uncertainties exist regarding the flux, sources and timi
The hydrates of the heavier noble gases Ar, Kr and Xe are easy to prepare, and they crystallize in two different structures1. The corresponding hydrates of He and Ne apparently do not exist. We now find by neutron powder diffraction experiments that, when applying He gas pressures of > 0.28...
