Scientists Get First Direct Look At How Electrons ‘Dance’ With Vibrating Atoms
Scientists at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have made the first direct measurements, and by far the most precise ones, of how electrons move in sync with atomic vibrations rippling through an exotic material, as if they were dancing to the same beat.
'Optical Metamaterials' Authors Will Accept 2014 Goodman Book Award From SPIE and OSA In August
Vladimir Shalaev of Purdue University and Wenshan Cai of the Georgia Institute of Technology will accept the 2014 Joseph W. Goodman Book Writing Award for their tutorial book Optical Metamaterials: Fundamentals and Applications in August. The biennial award is co-sponsored by SPIE, the international society for optics and photonics, and The Optical Society (OSA), and will be presented this year during the SPIE Optics + Photonics symposium in San Diego.
How To Measure The Performance Characteristics Of A Linear Motion Device
Once you've determined the requirements of your linear motion application, how can you qualify a linear motion product to ensure it meets your application's needs? Manufacturer's specs are often vague and/or incomplete. The only sure way is to test the product yourself. However, simply testing a product in the final application is usually not possible at such an early stage in the design process. This article will describe a series of tests that can be performed by the average user with little experience and without sophisticated measuring instruments to quickly determine the most important performance characteristics of linear motion systems.
