Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...

Mineral Composition and Full-Scale Pore Structure of Qianjiadian Sandstone-Type Uranium Deposits: Application for In Situ Leaching Mining

open access: yesGeofluids, 2022
In situ leaching (ISL) is becoming the main mining practice for sandstone-type uranium deposits in China. The key to ISL technology is to aid the leaching solution in contacting the ore bed over a large range, which will induce a series of chemical ...

Law and Mechanism of Different Electric Field Modes Enhancement Alkaline Leaching Sandstone-type Uranium Ore

open access: yesYuanzineng kexue jishu
China’s uranium resources are rich in reserves and deposits, but they are mainly low-grade uranium ores with low content of uranium. Sandstone-type uranium ores are mainly mined by in-situ leaching (ISL), but when the carbonate content is high, their ...

Nature's Nanotech Warriors: The Role of Metalloproteins and Protein Cages for Environmental Remediation

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Cartoon representation of five major classes of metalloproteins and their brief mechanisms of bioremediation. The five classes include metallothioneins, metal‐precipitating enzymes, P.‐type ATPases, protein cages, and synthetic metalloproteins (de novo‐designed proteins/peptides for selective adsorption). These natural and engineered protein structures

Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 2, Page 369-389, June 2026.
Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.
