Structural history of the southwestern corner of the Kaapvaal Craton and the adjacent Namaqua realm: new observations and a reappraisal [PDF]

, 1991
The rocks along the southwestern margin of the Kaapvaal Craton were deformed up to 7 times during the Early to Middle Proterozoic. The oldest deformation D1 is recorded in the N-S-trending Uitkoms cataclasite of pre-Makganyene age (>2.24 Ga) on the ...

Geology, Engineering and Humanities: three sciences behind the Malpasset dam failure (France, 2 December 1959)

Quarterly journal of engineering geology and hydrogeology, 2019
On 2 December 1959, the Malpasset arch dam in SE France suddenly failed, flooding the valley down to the sea, causing huge destruction and more than 400 deaths. Built from 1952 to 1954 for water supply and irrigation, filling of the reservoir was delayed

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

Advanced Energy Materials, EarlyView.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.
