The Next Generation of Current Measurement for Ionization Chambers

Ryan P. Fitzgerald, Denis E. Bergeron, Dean G. Jarrett, Neil M. Zimmerman, Carine Michotte, Hansjoerg Scherer, Stephen Giblin, Steven Judge
Re-entrant ionization chambers (ICs) are essential to radionuclide metrology and nuclear medicine for maintaining standards and measuring half-lives. Metrology

Spinal Helical Actuation Patterns for Locomotion in Soft Robots

Jennifer C. Case, James Gibert, Joran Booth, Vytas SunSpiral, Rebecca Kramer-Bottiglio
Spinal-driven locomotion was first hypothesized to exist in biological systems in the 1980's; however, only recently has the concept been applied to legged

The (R)Evolution of Refrigerants

Mark O. McLinden, Marcia L. Huber
As we enter the “fourth generation” of refrigerants, we consider the evolution of refrigerant molecules, the ever-changing constraints and regulations that have
