Abstract. This study presents local temperature and heat transfer coefficient distributions obtained experimentally on the internal surfaces of a rotating pin-finned brake rotor at realistic rotation speeds for braking (i.e., N = 100-300 rpm). To this end, the thermochromic liquid crystal technique in a rotating reference frame was employed. The results demonstrate that the bulk airflow ...

An energy-efficient mechanochemical route to hydrogen storage

The ball-milling gas absorption process consumes 76.8 KJ/s to store and separate 1,000 liters of gas. The method consumes 90% less that used in the petroleum industry's current separation process. Once absorbed into the powder, the gas can be transported safely and easily, and the material is heated in a vacuum to release the gas as needed.
