Performance and Sustainability Tradeoffs of Oxidized Carbon Nanotubes as a Cathodic Material in Lithium-Oxygen Batteries.

Climate change mitigation efforts will require a portfolio of solutions, including improvements to energy storage technologies in electric vehicles and renewable energy sources, such as the high-energy-density lithium-oxygen battery (LOB). However, if LOB technology will contribute to addressing climate change, improvements to LOB performance must not come at the cost of disproportionate increases in global warming potential (GWP) or cumulative energy demand (CED) over their lifecycle. Here, oxygen-functionalized multi-walled carbon nanotube (O-MWCNT) cathodes were produced and assessed for their initial discharge capacities and cyclability.

Examining the Temporal Demand and Sustainability of Copper in China.

A comprehensive study is carried out to determine (1) the annual historical demand and supply, (2) the annual prospective demand, and (3) the carrying capacity and future sustainability of copper resources in China. The results of the first analysis show that both the demand and the supply have substantially increased since 2000 after remaining relatively minute for the period from 1950 to 2000. By 2015, the per capita total and domestic demands had reached 7.

Forecasting the temporal stock generation and recycling potential of metals towards a sustainable future: The case of gallium in China.

Gallium is one such co-product mineral, being used for consumer electronics and contemporary renewable energy applications. China is the top producer of gallium and supplies over 70% of global demand. However, supply uncertainty of primary gallium is increasing due to a shortage of reserves.

Shape-Dependent Surface Reactivity and Antimicrobial Activity of Nano-Cupric Oxide.

Shape of engineered nanomaterials (ENMs) can be used as a design handle to achieve controlled manipulation of physicochemical properties. This tailored material property approach necessitates the establishment of relationships between specific ENM properties that result from such manipulations (e.g.
