Cell Adhesion in Nanotribology with Aracely Rocha

In this episode, we talk to Aracely Rocha, who has been doing research in the field of nanotribology for biological applications. Her focus has been on how materials at various scales interact with biomolecules. She has tried to quantify this interaction through adhesion. In a paper, Aracely and her co-authors posit that "measuring cell adhesion has become critical for design and development of materials and devices for biological applications." Her work could impact a number of biological applications, including improving the life of artificial joints, or the efficiency of drug delivery.

In addition to her work in the field, Aracely is involved in many different ways as a student member of STLE. Most recently, Aracely participated and received the Gold Level award in the Student Poster Competition at the 2011 Annual Meeting, for her work "Protein Adhesion to TiN and CrN Coatings." To see a full list of the award winners, click here. Aracely has also been a Program Session Chair at a previous STLE Annual Meeting and is now involved with her University's newly formed student chapter. Getting involved has its rewards.

Tribochemistry and Nanoscale Surface Interactions in Nanotribology with David Huitink

In this episode, we discuss the interesting and growing field of nanotribology from a PhD student's perspective. David Huitink attends Texas A&M and is active in STLE. Most recently, he founded the Texas A&M University Chapter of STLE and served as its President in 2010. Listen as David discusses his work: using nanoscale contact to study friction and tribochemical reactions. This involves studying the chemical and interfacial reactions taking place at the nanoscale as a result of friction and contact forces.
