TL;DR: In this article, the carbon monoxide oxidation reaction (COOR) on Mn atoms embedded in single and double-vacancy graphene was investigated (MnC3 and MnC4).

TL;DR: N nanoscale curvature provides a new degree of freedom to manipulate 3D graphene electrical properties, which may pave a new way to design new 3D graphene devices with preserved 2D electronic properties and novel functionalities.

TL;DR: In this paper, the authors reported that the stability of a metallic glass can be dramatically improved by slow deposition at high temperatures, and they also showed that the exceptional properties of the ultrastable glass are associated with abundance of medium range order.

Abstract: We report an anomalous brittle-to-ductile transition (BTDT) in Au-based bulk metallic glasses (BMGs). Despite of brittle failure without noticeable plastic strain under uniaxial compression at room temperature, the Au-based BMGs exhibit remarkable plasticity at cryogenic temperatures, which is opposite to the BTDT in crystalline materials. This anomalous transition originates from the strong temperature dependence of the fundamental deformation units, viz. shear transformation zones, giving rise to both superior plasticity and high strength of BMGs for low-temperature applications.

TL;DR: In this article, the performance of polypyrrole (PPy) in non-aqueous electrolytes can be dramatically improved by highly conductive nanoporous gold which acts as both the support of active PPy and the current collector of supercapacitors.
