Small-diameter ballscrew assemblies from Nook Industries are designed for smaller-footprint applications including robots, unmanned vehicles, and guided missiles. Converting rotary motion to linear motion, the units feature a load capacity of 40 to 100 lb, diameter of 6 to 12 mm, and standard leads from 1 to 3 mm. Lead accuracy is ±100 µm/300 mm for standard rolled and ±25 µm/300 mm for precision rolled. The devices are typically powered by a motor that generates torque as the rotating screw pushes the nut along the screw shaft, producing linear thrust. They are often used with linear slides or as part of a linear actuator to move parts and devices along a single axis. Materials include alloy, stainless, aluminum, titanium, and other exotic metals.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.

France's Dassault Aviation and India's Reliance Group announced in late September 2016 the creation of a joint venture (JV) in India called Dassault Reliance Aerospace. With this announcement came news that the Dassault Reliance Aerospace JV will be a key player in the execution of offset obligations as a part of the 36 Rafale fighter jet purchase agreement that was signed between France and India on September 23, 2016 and is valued at around €7.87 billion, or about Rs. 59,000 crore.

One of the biggest issues in bringing forward new designs is the length of time that it takes to agree to a new specification, research and evaluate the alternative features and configurations, and then embark on a development program that will take the design to flight testing and ultimately operational service.
