Study on the Causes for ICP-MS Signal Intensity Declination of Os Water Absorption Liquid

Yankuang ceshi, 2018
BACKGROUND Os can be separated from the sample matrix by distillation, and the absorbing liquid can be introduced into ICP-MS directly, which is a key step of the molybdenite Re-Os isotopic age analysis.

Uranium-Lead dating of hominid fossil sites in South Africa [PDF]

, 2005
Discoveries of hominid, or apeman, fossils in the twentieth century have brought human evolution into the scientific spotlight. It is important that ages are assigned to such hominids so that their place in human evolution can be established.

Re–Os isotope geochronology of the Shangbao pyrite–flourite deposit in southeastern Hunan, South China: Evidence for multiple mineralization events and the role of crust–mantle interaction in polymetallic deposits

Solid Earth Sciences, 2017
In South China, both crustal reworking and crust–mantle interaction were important geological processes during the Paleozoic and Mesozoic eras. However, the relationships between these two processes and metal mineralization are still unknown.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

Advanced Science, EarlyView.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.

Re-Os Isotope Dating of the Natural Micro/Nano Silicon-Carbon Deposit in Fengcheng City, Jiangxi Province

Yankuang ceshi, 2023
BACKGROUNDThe micro/nano silicon-carbon deposit in Fengcheng City, Jiangxi Province, is the first sedimentary deposit mineralized by phytoliths in the world. According to the research carried out here, micro/nano silicon-carbon ore may have been formed by the long-term accumulation and consolidation of phytoliths.
