The Rio Grande Symposium on Advanced Materials (RGSAM) is a general technical meeting of materials researchers in the Rio Grande geographic region. It is an outgrowth of the Joint Technical Meetings of the New Mexico Section of the American Ceramic Society and the New Mexico Section of the Materials Research Society initiated in 1989. These meetings, sub-titled “Ceramics and Advanced Materials: Symposia and Poster Session,” proved to be quite popular among materials researchers in the Rio Grande geographic region. Attendance typically ranged between 75 and 150 people presenting 30 to 50 presentations, which were frequently used as a local warm-up for national meetings. An important aspect of this symposium is that it has been, and continues to be a venue for presentations by students from regional universities. In 1997, the Albuquerque Chapter of ASM International joined with the NM Section of the American Ceramics Society to host the meeting which began its new name, “The Rio Grande Regional Symposium on Advanced Materials.” Reflecting the multidisciplinary nature of materials research presented at RGSAM, other societies soon joined to host the symposium. The New Mexico Chapter of the American Vacuum Society organized the RGSAM in 2013, followed by the Central New Mexico Local Section of the American Chemical Society in 2015. This meeting hopes to reach out to a broad base of support among local materials societies and will be a focal point for the exchange of technical information in the Rio Grande geographic region well into the 21st century.
At the core of this meeting is the Kreidl Memorial Lecture, honoring the career achievements of Norbert Kreidl, a remarkable and indefatigable glass scientist who spent his final years as a consultant based in Santa Fe, New Mexico.
The Kreidl Lecture has featured several prominent ceramists and glass scientists.
Kreidl Lecture Abstract
The Evolution of Strong, Fast, Powerful, Durable, and Cheap Polymer Artificial Muscles from Carbon Nanotube Muscles
Three successive generations of twist-spun artificial muscles are described that provide both torsional and tensile actuation. Our first generation of twist-spun muscles, which are electrochemically powered by volume changes induced by double-layer charge injection, provide torsional rotation speeds of 590 rpm, and torsional strokes of 250° per millimeter of actuator length, which is 1000 times that for earlier artificial muscles. Our second generation muscles, which require no electrolyte and are based on guest-infiltrated carbon nanotube yarns, can torsionally actuate at 11,500 rpm and deliver 85 times higher power density during contraction than natural muscles. Our third generation muscles, which are thermally, electrothermally, or chemically powered polymer fibers, can rotate at 100,000 rpm, contract by up to 49%, generate 5 times the gravimetric power of a car engine, lift 100 times heavier loads than the same length and weight human muscle, or actuate at 7.5 cycles/s for millions of cycles. These polymer muscles can be cheaply made from fishing line or sewing thread. The strokes of these polymer muscles has be increased to a remarkable ±9000% and their applications in areas as diverse as thermal energy harvesting and comfort-adjusting textiles will be described. This work resulted from collaboration between The University of Texas at Dallas, The University of Wollongong (Australia), Hanyang University (South Korea), The University of British Columbia (Canada), and Namık Kemal University (Turkey).
