A heat pump at a molecular scale controlled by a mechanical force
, 2006 We show that a mesoscopic system such as Feynman's ratchet may operate as a heat pump, and clarify a underlying physical picture. We consider a system of a particle moving along an asymmetric periodic structure . When put into a contact with two distinct

Influence of orientation and radiative heat transfer on aluminum foams in Buoyancy-induced convection [PDF]
, 2015 Two differently-produced open-cell aluminum foams were compared to a commercially available finned heat sink. Further, an aluminum plate and block were tested as a reference. All heat sinks have the same base plate dimensions of four by six inches.
