Computer simulations suggest that creating hot and cold regions within a specific arrangement of semiconductors generates internal electric currents and magnetic fields. If borne out by experiments, the new effect, reported 8 July in Physical Review B, could lead to improvements in electronic devices that heat up in use. Experts are intrigued by the effect but remain cautious about its practica...

battery pack is the main energy storage element, and directly affects the performance of electric vehicle. this paper selects the forced air cooling of horizontal battery pack as the study object, and researches the heat dissipation performance of different operating conditions with fleunt software. results indicate that: according to the four kinds of transient state conditions and steady stat...

The monitoring of processor temperature is crucial to increase its efficiency. One the novel approaches use information not only about CPU (Central Processing Unit) thermal state, but also changing environmental conditions. additional difference sensor monitor changes in environment necessary. dedicated for active heat sink, often used inside laptops, was designed, fabricated and investigated. ...

Abstract Usually, high temperature decreases the output performance of triboelectric nanogenerator because dissipation charges through thermionic emission. Here, a difference is designed and fabricated to enhance electrical in environment. As hotter friction layer’s 0 K 145 higher than cooler part’s temperature, voltage, current, surface charge density power are increased 2.7, 2.2, 3.0 2.9 time...

Abstract—Closed die forging is a very complex process, and measurement of actual forces for real material is difficult and time consuming. Hence, the modelling technique has taken the advantage of carrying out the experimentation with the proper model material which needs lesser forces and relatively low temperature. The results of experiments on the model material then may be correlated with t...

For a better understanding of the mechanisms behind cellular functions, quantification of the heterogeneity in an organism or cells is essential. Recently, the importance of quantifying temperature has been highlighted, as it correlates with biochemical reaction rates. Several methods for detecting intracellular temperature have recently been established. Here we develop a novel method for sens...
