These interactions are often sources of failure or inefficiency, causing increased energy consumption (high friction) and unnecessary material waste (excessive wear). A report released by the Advanced Research Projects Agency (ARPA) in February 2017 evaluated the energy consumption of the United States and potential energy savings that could be applied through the application and targeted research efforts in <strong>tribology (the study of friction and wear)<\/strong>. The report states the US currently consumes about 97.2 Quads (~28.5 trillion kWh) per year, and postulates that application and advancement of tribological materials could reduce US energy demand by nearly 11%!<\/p>\n<p>One of the largest areas of energy consumption is the transportation sector, which accounts for more than a quarter of all energy consumption in the US<sup>1<\/sup>. In passenger cars for example, 16 % of all fuel energy is consumed by frictional losses in the engine and transmission<sup>2<\/sup>.

To run these experiments properly, students will design and assemble instruments that can be used to test a wide range of material systems (gels, polymers, metals, and ceramics) at a variety of length scales, environments, and temperatures. This experience teaches students fundamentals of data acquisition, control, instrumentation, machine design, and manufacturing. These instruments will research fundamental and applied aspects of friction, wear, and adhesion of materials.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is Tribology? tribology- (n)\u00a0a study that deals with the design, friction, wear, and lubrication of interacting surfaces in relative motion (as in bearings or gears) &#8220;tribology.&#8221;\u00a0Merriam-Webster.com. 2018. https:\/\/www.merriam-webster.com (18 December 2018).
