Ball-screw systems are for applications where precise positioning and high thrust, speed, and stiffness are required. Brochure describes a variety of packaged, machine-tool caliber, precision ball-screw linear actuators, machine slides, and sealed multi-limit switch units. The literature provides selection criteria, photographs, and descriptions of applications.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
