Three long-chain alkanes detected by Nasa’s Curiosity rover could be chemical biosignatures that point to a history of past ...
For more than a decade, a robotic explorer has been traveling across Mars, quietly collecting clues about a time when the Red ...
‘There is evidence that liquid water existed in Gale Crater for millions of years and probably much longer, which means there ...
The longest organic molecules identified to date on Mars have recently been detected. These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the ...
While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical ...
NASA’s Curiosity Martian rover finds organic-like, long-chain alkanes preserved in the planet’s mudstone Twelve years after ...
Presently, there is a deficiency in constitutive equations capable of characterizing mudstone behavior under combined stress and swelling. To tackle this challenge, the deformation characteristics of ...
In southern Iraq, archaeologists have excavated a remarkable collection of carved clay tablets—ancient records of Akkadia, the world’s oldest empire. Marked with the administrative details of ...
XRD results indicate that the primary mineral components include clay, quartz, feldspar, calcite, and dolomite, with trace amounts of gypsum, halite, and pyrite. Clay content varies from 3.45% to 74.7 ...
This study examined the influence of kaolin clay as drilling cuttings on barite-weighted oil-based drilling fluid (OBDF). Different quantities of kaolin clay (0, 5, 10, and 15 wt %) were intentionally ...
