Episode 11 | The Tribology of Eating Chocolate

Contributors: Dr. Neil Canter, STLE Advisor, Technical Programs and Services, Dr. Siavash Soltanahmadi, Research Fellow, University of Leeds, UK 

Release date: November 16, 2023 | 22 min

 

The role of tribology in facilitating the move to sustainability does not just involve reducing friction and wear in industrial machinery and automobiles, but also is critical in gaining a better understanding of what we eat and what steps can be taken to improve the availability of healthier foods. This episode focuses on the topic of chocolate and research that is ongoing to better understand how this food is eaten and how tribology is used to better understand this process. A discussion is held with Dr. Siavash Soltanahmadi, Research Fellow at the University of Leeds (UK), who describes ongoing research trying to better understand the process of eating dark chocolate. When eating a piece of chocolate, an enjoyable sensation is felt due to the creamy feel of this food which provides a textural sensation. In discussing the eating of chocolate, a phase transfer takes place as the solid chocolate transitions into a molten fat phase followed by introduction of saliva, leading to the formation of an emulsion as digestion is initiated. Through a series of studies using a tongue-like surface, oral tribology is used to better understand the eating process. From this work, a multiscale tribology-informed smart design of chocolate is proposed that uses a gradient technology to retain the pleasurable eating sensation, but reduces the fat content of chocolate, leading to a healthier food.

Episode 10 | Tribology Testing

Contributors: Dr. Peter Lee, FSTLE, Institute Engineer and Chief Tribologist, Southwest Research Institute, George Plint, Director, Phoenix Tribology Ltd., and Dr. Dirk Drees, CEO, Falex Tribology Belgium

Release date: April 12, 2023 | 32 min
 


Tribology, the scientific study of lubrication, friction and wear, is as old as the world itself and can be found in almost every application. The word itself was not entered into the English dictionary until 1966 at the time of The Jost Report. The use of tribology to solve friction and wear problems through the life cycle of a product from manufacture, use and recycling can be used to improve sustainability. This podcast looks at how tribology testing can be used to improve sustainability, and benchtop rigs can be used to scale down full-size application and achieve usable realistic results that can then be scaled back up for real-life applications.
 

Episode 9 | Hydrogen as a Fuel for an Internal Combustion Engine

Contributors: Dr. Neil Canter, STLE Advisor, Technical Programs and Services, Mike Copeland, Owner and CEO, Arrington Performance

Release date: October 5, 2022 | 26 min
 


The search for finding a way to commercialize vehicles that generate no emissions has led the automotive industry to work with batteries and fuel cells. But another approach is to take the basic internal combustion engine (ICE) and substitute hydrogen as a fuel for both gasoline and diesel fuel. This podcast examines the potential for hydrogen internal combustion engines. In this engine, hydrogen reacts with oxygen in the air as part of a combustion process, but the only byproduct is water. The initial results are quite favorable. Without the use of hydrocarbon fuels, the ICE runs much cleaner and the motor oil used is not impacted. The motor oil looks as pristine as when it was initially put in the engine. There is the potential for the motor oil to last at least 50,000 miles. The conclusion from this podcast is that hydrogen not only has the potential to be a short-term answer to reduce automotive emissions but could also be a long-term solution.

Episode 8 | Nuclear Power – A Clean Energy Option

Contributors: Dr. Neil Canter, STLE Advisor, Technical Programs and Services, Robin Manley, Vice President, New Nuclear Power Development, Ontario Power Generation

Release date: July 26, 2022 | 37 min
 


Nuclear power is emerging as a viable energy generation option that does not release greenhouse gases in contrast to fossil fuel energy sources. While the nuclear power industry has come under scrutiny due to past issues with specific plants, overall, the industry practices excellent safety protocols and nuclear power plants operate in a very safe manner. Currently, nuclear power contributes about 10 percent of global electricity production behind coal, gas, and hydro, according to a 2019 study by the International Energy Agency (IEA). There is interest in bringing on additional nuclear power capacity to assist with reducing greenhouse gas emissions attributed to power generation. This episode includes a discussion with a representative from the nuclear power industry to get an update on whether adding more nuclear power plants is under consideration as an energy generating option. This podcast focuses on the growing interest in using small modular reactors (SMRs), which are downsized versions of existing nuclear power plants that can be designed for operation in specific locations that may be remote or have a specific power requirement that cannot be handled by existing power generation options. Prefabrication of the components used in SMRs is discussed, as this is an advantage in reducing the cost of manufacturing nuclear reactors. Components can be shipped to the location where the SMR will be placed and installed at that point in a similar manner to using Lego bricks. Episode Transcript
