Researchers devise method to suppress thermal conductivity to improve thermoelectric materials for waste heat recovery

Green Car Congress

A new study published in the journal Nature Materials has found a way to suppress the thermal conductivity in sodium cobaltate so that it can be used to harvest waste energy, with potential applications such as automotive waste heat recovery. Resources. CoO 2 , which has a large-period superstructure. Voneshen, K.

Fraunhofer team develops process to recycle carbon black from car tires

Green Car Congress

Waste tires have been used mainly for recovering energy sources; only small proportions of the carbon black contained in these tires are recycled, since mineral ash accounts for around 20% of its content. Top, primary product from left to right: raw rCB, clean rCB (96+), pearlized clean rCB (96+). © Fraunhofer IBP.

ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium. In a bench-scale demonstration, the LDH sorbent recovered more than 91% of lithium from a simulated brine. Lili Wu, Samuel F.
