In our latest episode, author Peter Blau discusses his book, Friction Science and Technology - From Concepts to Applications.
Peter goes over how the book came about, how it differs from other books on the subject, the topics included, the intended audience and its use - how to apply the concepts presented.
His thoughts on the future of the field: "I would hope that those who practice tribology will realize that it isn’t so much a single discipline as it is a set of multi-disciplinary problems that use whatever tools are appropriate in each case."
This quote makes sense, since the book itself is all about covering core concepts and applying those concepts to a variety of conditions.
As you may have guessed, space tribology is the application of tribology and lubrication principles in the space environment. The field addresses the reliable performance of machines in space, including satellites, spacecraft, and even the International Space Station (ISS). These instruments and structures require lubrication and it is a challenge to create lubricants that can handle this extreme environment.
Brandon Krick, a Ph.D. student who attends and works at the Tribology Lab at the University of Florida discusses space tribology and MISSE7, or the Materials on the International Space Station Experiments, 7th Mission. He was involved in the development and implementation of the MISSE7 and will handle the analysis of the experiments upon conclusion. He is shown here with one of the tribometers.
This experiment is being conducted with NASA's help, and addresses the use of solid lubricants in low earth orbit. The experiment is a test bed for materials and coatings attached to the outside of the ISS being evaluated for the effects of the space environment. The results of this experiment will provide a better understanding of the durability of various materials, thus providing information for applications in the design of future spacecraft. For more on the experiment and space tribology, you can download this week's episode, read the transcript, or listen directly from the slider bar above.
For more information on space tribology, MISSE7, Brandon, or his graduate advisor, Dr. Gregory Sawyer, you can visit our website, the University of Florida's Tribology Laboratory website, or NASA's page on MISSE7. You can also read the TLT article, "History's Ultimate Lube Job."
In this episode, we talk to Dr. Neil Canter, who runs his own consulting company, Chemical Solutions. Dr. Canter discusses his feature article in the latest issue of Tribology & Lubrication Technology.
There has been a struggle to define the words "green" and "sustainable" and there is no commonly agreed upon definition. Dr. Canter presents a definition and his argument for that definition. Instead of looking at a lubricant at the cradle and the grave, he argues for a look at the application and use of a lubricant, and labeling a lubricant "green" by what happens in process.

Make sure you read the article, "What is 'Green?'" in this month's TLT magazine, which is available both in print and online. Peruse the digital version of TLT, which contains other articles and perspectives on what it means to be "green." You can visit our website for more news and information on the subject.
You can also learn more about the subject by attending the 2011 STLE Annual Meeting in Atlanta, Georgia. Dr. Canter is the Vice Chair of a full-day education course discussing bio-based lubricants and bio-based fuels. You can view the course synopsis for more information on the topics and format of the course on our webiste.
In this episode, Dr. Ian Clarke, Co-Director of the DARF Center, discusses the wear involved with hip and knee joint replacements, and his current work conducting wear analysis of metal-on-metal ("MOM") bearing implants that have failed in patients. His goal is to determine why this small percentage of implants have failed. Despite some issues with these "MOM" bearings, Dr. Clarke argues that the vast majority of implants are successful and result in improved quality of life.
As he gets to see and test implants from ten to fifteen years ago, this gives him an insight into what implants were designed and created then, the materials and composition being used, what works and what does not work. He is also testing implants that may be used in the future to ensure they have the longest life span. To the right, you can see the machine used to conduct wear analysis of a potential hip implant.
Dr. Clarke's unique point of view provides the most benefit to all those involved in the design of joint replacement technology - most important of all, the patient.
Essentially, this technology is one that provides a way to improve a patient's life, and is being refined through these types of studies to ensure the replacement is a successful and beneficial one for the patient.

You can also attend the 2011 STLE Annual Meeting, which has a biotribology technical track.

In this episode, we talk to Dr. Michael Dugger, Distinguished Technical Staff Member at Sandia National Laboratories. Dr. Dugger discusses nanotribology and MEMS (micro-electrical-mechanical systems). MEMS are small mechanical devices that are driven by, or have as their output, electrical signals.
According to Dr. Dugger, nanotribology is "the study of interactions of small collections of atoms involving relative motion between one group of atoms and another." Nanotribology is a key component of nanotechnology and its development. According to an article in TLT from January 2009, "a dozen nano products are commercially introduced each month-and lubrication issues are at the heart of nearly all of them." Lubrication at the nano scale is fundamentally different and requires a different approach because what works on the normal scale, may not work in an application at the nano scale.
Dr. Dugger is one of many working and researching in this area, attempting to discover what lubrication methods work best and how to apply this research to the use of MEMS. Here, you can see the scale of a typical friction device that is used at Sandia.
This episode takes another look at biotribology, focusing on the heart. In the interview we talk with Dr. Said Jahanmir, President and CEO of MiTiHeart Corporation. Dr. Jahanmir has specialized in this area of research, which focuses on patients with congestive heart failure (CHF). CHF refers to a situation where a patient's heart cannot pump enough blood to meet the body's needs, and it affects 4.5 million people annually. This population sometimes requires medical intervention, and a blood pump is one source of that assistance.
Tribology is a necessary requirement when designing, creating, and implanting devices that assist the heart. If these issues are not considered, the pump could have adverse effects on the blood, tissues and the heart.
One type of blood pump, called an LVAD or left ventricular assist device, is in development at MiTiHeart. Dr. Jahanmir addresses the design, testing and impact that this LVAD will have. In the picture, you can see the relative size and shape of the LVAD.
If you'd like to hear more, you can download the podcast, subscribe to get future episodes, or view the transcript. You can also continue the conversation by reading Dr. Jahanmir's article in TLT. The STLE website has many resources that you can use to find more information, including more on the biotribology technical tracks at both the International Joint Tribology Conference and the upcoming 2011 STLE Annual Meeting, as well as information on Dr. Jahanmir and his work at MiTiHeart.

Biotribology as a field has been defined as the study of friction, lubrication and wear in biological systems. In this field, there has been significant focus on joints, including the hip, with a large amount of research devoted to hip replacements. Biotribology as a field is more expansive and looks at any biological application, including structures like the heart and the eye. Today’s podcast addresses the field in general and ocular tribology specifically.
In the interview, we talk with Alison Dunn, a PhD candidate at the University of Florida, who has specialized in this area of research. Listen to find out more.
