DARPA to Develop Advanced Tiny Chip-Scale Atomic Clocks for Military PNT Applications

Defense Advanced Research Projects Agency (DARPA) is presently working on an advanced version of its first-generation, battery-powered, miniature chip-scale atomic clock (CSAC) with 1000x performance improvements for positioning, navigation, and timing (PNT) applications. DARPA’s Atomic Clock with Enhanced Stability (ACES) program aims to build the next-generation atomic clock owing to the limitations of the now

Researchers Can Now Predict Properties of Disordered Polymers

In a new study, scientists used a combination of theory, experiment, and simulation to read patterns on long chains of molecules to understand and predict the behavior of disordered strands of proteins and polymers. The work offers detailed insights on the physics behind the precise sequence of charged monomers along the chain and how it

World’s First Operational 3D Printed Excavator

For the past two years a conglomerate of trade associations, industry, government and academia have been collaborating on the world’s first operational 3D printed excavator. That project made a giant leap forward with the recent printing of a prototype that leveraged large-scale additive manufacturing technologies and further explores the feasibility of printing with metal alloys.
