Continuous improvements of quantum cascade laser (QCL) technology have extended the applications in environmental trace gas monitoring, mid-infrared spectroscopy in medicine and life science, law enforcement and homeland security and satellite sensor systems. We present the QCL based emissivity monitor for the CORSAIR blackbody. The emissivity of the blackbody was designed to be better than 0.9...

We have investigated electronic cooling of suspended nanowires with SINIS tunnel junction coolers. The suspended samples consist of a free standing nanowire suspended by four narrow (∼ 200 nm) bridges. We have compared two different cooler designs for cooling the suspended nanowire. We demonstrate that cooling of the nanowire is possible with a proper SINIS cooler design.

Cryotherapy is one of most popular treatments for treating injuries using cold applications due to various advantages that have been accepted by medical professionals like safe use and able reduce pain inflammation if the treatment given according specifications. The existing devices in market such as cryo-cuff will become more efficient it capable control important parameter cooling temperatur...

This paper presents environment friendly refrigerant R290 as a solution to the environmental concerns like depletion of ozone layer and rise in global warming because of wide use of synthetic refrigerants R22 and R134a. The water cooler is the widely used refrigeration application in warm climatic countries. Refrigerant R22 and R134a are predominantly used refrigerants in water cooler refrigera...

Thermoelectric air condition system (TEACs) powered by solar photovoltaics is useful for thermal comfort applications, especially when there a direct energy source like sunlight. This paper presents experimental investigations of solar-powered thermoelectric conditioning both cooling and heating modes. The experiments were carried out in test room whose volume 1 m3 under the climatic conditions...
