Undergraduate researchers show off research skills in poster shows

Event Date: April 12, 2016
Undergraduates Adrian Ruiz and Qianru Sally Jia participated in the Undergraduate Research and Poster Symposium on April 12. Adrian placed 2nd overall in the poster competition. Undergraduate Yu Han will participate in the Bottomley Undergraduate Research Scholarship Poster Show on April 27.

Adrian Ruiz (2016 SRC Undergraduate Research Fellow): Passive Thermal Management using Phase Change Materials

Project Goals:

  • Develop a thermal management solution based on phase change materials (PCMs) in order to store energy generated by transient and localized hotspots in processors.
  • Test which integration method and which PCMs will prove most useful for the use in passive thermal management in cellphones.
  • Enable devices to operate at a higher performance level for longer periods of time.
 
Qianru Sally Jia (2015 Perry Undergraduate Research Scholar): 3D Printing of Nanostructured Thermoelectric Devices
 

The ultimate goal of this project is to enable 3D printing of nanostructured thermoelectric devices on flexible substrates and measure the properties of the devices.

Task 1: Fabricate a inkjet 3D printer that can print customized thermoelectric device and synthesis suitable nanostructured inks

Task 2: Simulation of the Harman method to ensure the preciseness of TE measurement

Task 3: Measure the TE efficiency of different samples

 

Yu Han (2016 Bottomley Undergraduate Research Scholar): Influence of 3D Infill Pattern on Thermal Transport

Yu Han with his poster on 3D Printed Structure
  • Most modern 3D printers do not print fully dense structures. Instead, the printed part has an infill pattern that leaves empty space inside the printed parts to save the material and time (see figures to right).
  • This causes the properties of the printed part to be anisotropic (not the same in each direction) and to vary with the infill pattern and infill density.
  • Generally, the toolpath\infill pattern yields orthotropic material properties (3 planes of asymmetry).
  • This goal of this research is to measure the impact of toolpath and infill pattern on thermal properties of 3D printed parts.
