Band gap closure, incommensurability and molecular dissociation of dense chlorine

Nature Communications, 2019
Molecular systems are predicted to transform into atomic solids and be metallic at high pressure; this was observed for the diatomic elements iodine and bromine. Here the authors access the higher pressures needed to observe the dissociation in chlorine,

Experimental evidence for a shallow cumulate remelting origin of lunar high-titanium mare basalts

Communications Earth & Environment
High-titanium mare basalts were among the earliest rocks to be returned from the Moon, but key aspects of their formation remain enigmatic. Here we show twenty partial remelting experiments conducted on three bulk compositions based on shallow ilmenite ...

Peer Pressure and Manager Pressure in Organisations *

We study the interaction between horizontal (peer) and vertical (manager) social factors in workers’ motivation. In our setting, individuals work using open-plan desks. Using a natural experiment, we identify a sharp increase in workers’ productivity following the occupation of adjacent desks. We link this peer pressure effect to two key aspects of the

Unveiling a novel metal-to-metal transition in LuH2: Critically challenging superconductivity claims in lutetium hydrides

Matter and Radiation at Extremes
Following the recent report by Dasenbrock-Gammon et al. [Nature 615, 244–250 (2023)] of near-ambient superconductivity in nitrogen-doped lutetium trihydride (LuH3−δNε), significant debate has emerged surrounding the composition and interpretation of the ...
