Nanophysics for Energy Efficiency

Descripción

Soon after the invention of the Scanning Probe Microscopies family (STM and AFM), an AFM was modified to be able to measure friction forces. Subsequent developments led to their use in studies of scratching, wear, and indentation and measurements of mechanical and electrical properties. Now they are routinely used in many fields including micro/nanotribology. Before becoming involved in Scanning Probe Microscopies (SPMs), the author had carried out projects in Nanophysics, in particular single-molecule experiments and weak interactions from quantum nature, which include molecular beams and nanoscopic/spectroscopic analyses. Collaboration of Nanotribology and Scanning Local Probes was timely expected and in 1996, I organized with the author the NATO Study Advanced Institute on Micro/Nanotribology in Sesimbra, Portugal, where important and interesting results were presented. The development of this field has attracted numerous physicists and SPMs in Nanotribology have made an immense impact on the field of Advanced Nanotechnology. As an example, studies with SPMs involve properties and size scales of critical relevance to energy-related components. As a pioneer of Nanotribology I must say that advanced local probe techniques and in particular emergent scanning probe microscopy methods addressing several nanoscale functionalities have been gradually implemented in energy storage and conversion applications. Friction is also an important limitation of energy efficiency performances in electro-mechanical components and some SPM techniques already are used for electric energy storage studies to study nano-friction.
