Gypsum Gardens: Self‐Assembled Tubular Structures of Calcium Sulfate with Relevance for the Detection of Extraterrestrial Life

open access: yesAngewandte Chemie International Edition, EarlyView.
Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.

Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

MINERALOGY OF THE OVERBURDEN ROCKS OF THE KOKLAN W-MO DEPOSIT (SOUTH URALS) [PDF]

open access: yesМинералогия, 2015
The Koklan W-Mo deposit is overlapped by Mesozoic-Cenozoic rocks 120–140 m thick, which may be subdivided in four members on the basis of variable proportions of the rock-forming minerals (quartz, hydromica (with glauconite), smectites and X-ray ...

The Mineralogy of Scotland [PDF]

open access: yesNature, 1901
NO book is of more use to the practical mineralogist and collector than one which describes in a detailed manner the mineral localities of a country. Among the best examples are the lexicon of Zepharovich and Becke for Austria; that of Frenzel for Saxony; and, on a much more elaborate scale, the treatise by Lacrox on the mineralogy of France and her ...

Unlocking Zero‐Carbon Buildings via Solid‐State Energy Storage Wallboards Enabled by Superionic Oriented Layered Magnesia‐Cement Electrolytes

open access: yesCarbon Energy, EarlyView.
Schematic of OLMC/PAM‐based CSESWs integrated with distributed photovoltaic systems for zero‐carbon buildings. The composite solid electrolytes proposed in this study are designed by creating novel OLMC architectures, where PAM gel electrolytes are incorporated into the oriented interlayers and act as the fast ion transport medium.
