DESCRIPTION:Speakers: Othmane Mouane (University of Witwatersrand)\, Edwar
 d Nkadimeng (University of the Witwatersrand)\nIn this study\, the incorpo
 ration of 0D and 1D carbon nanomaterials in a commercial thermal interface
  material is reported to enhance the heat transfer of electronic devices. 
 The investigated thermal interface materials were fabricated following a p
 rotocol based on sonication of the carbon nanomaterials and the thermal co
 mpound in acetone at 55 °C. In order to test the applicability of the fab
 ricated thermal interface materials\, a setup was designed to simulate the
  operating conditions of standard electronic components. The experimental 
 setup monitored the heat dissipation and transmission to the heat sink and
  allowed the acquisition of the data by means of LabVIEW software. The rol
 e of the carbon nanomaterials incorporated was studied by varying the mass
  in the thermal interface materials in a range between 0 and 10 %. The lar
 ge heat transfer is reported with thermal interface materials containing 1
 % of carbon nanomaterials\, corresponding to a temperature drop of 2 °C. 
 In addition\, the thermal resistance Rth of the thermal interface material
 s was characterised by the ASTM D5470 approach. The reproducibility and re
 liability of the reported results were shown as part of the study. These m
 easurements are found to be in accordance with the testing stand results. 
 The new thermal interface material was tested in the low voltage power ele
 ctronics and a temperature drop of over 5 °C was observed. The use of the
 se new thermal interface material as part of the current upgrade of the AT
 LAS detector at CERN will have good impact\, such as protecting the electr
 onics from overheating and will expand their life span.\n\nhttps://indico.
