Columbia Marking Tools­' Air Impact Markers are air-powered devices that instantaneously indent a permanent mark into metal surfaces, providing traceability for analyzing and tracking parts and production processes. The markers use lower electrical energy than laser and dot peen markers, and they do not have the chemical disposal issues of inkj­et markers. They have few mechanical parts and are self-contained for ease of application and use. The markers feature an air-actuated rod housed within a cylinder that contains and efficiently vents compressed air, a stamp holder that is typically integrated with the rod, and a stamp. By encapsulating the internal resonance sound within the iron composite casting, the marking action results in a 44% reduction in noise level. Operation is initiated via a four-way air valve, and the internal air controls complete the automatic cycle.

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.
