A breakthrough Cu-Ta-Li alloy has the potential to revolutionize aerospace, defense, and industrial applications. Researchers from the U.S. Army Research Laboratory (ARL) and Lehigh University have developed an advanced nanostructured copper alloy that sets a new benchmark for high-temperature perf
The frequency regime lying in the shortwave infrared (SWIR) has very unique properties that make it ideal for several applications, such as being less affected by atmospheric scattering as well as being “eye-safe.” These include Light Detection and Ranging (LIDAR), a method for determining ranges and distances using lasers, space localization and mapping, adverse weather imaging for surveillance and automotive safety, environmental monitoring, and many others.
However, SWIR light is currently confined to niche areas, like scientific instrumentation and military use, mainly because SWIR photodetectors rely on expensive and difficult-to-manufacture materials. In the past few years, colloidal quantum dots —solution-processed semiconducting nanocrystals—have emerged as an alternative for mainstream consumer electronics.
While toxic heavy-metals (like lead or mercury) have typically been used, quantum dots can also be made with environmentally friendly materials such as silver telluride (Ag2Te). In fact, silver telluride colloidal quantum dots show device performance comparable to their toxic counterparts. But they are still in their infancy, and several challenges must be addressed before they can be used in practical applications.
Chinese researchers say they found jet’s potential vulnerability in study of simulated combat involving Taiwan.
“No two ways about it,” Altepeter told Breaking Defense today. “The number of companies that we’re announcing is a surprise to me. I did not expect we would get this many.”
For the winning teams, the value of QBI is not just the money. Indeed, first-round grants like those being announced today have typically been under $1 million — small change not just for the Pentagon but for tech firms and venture capitalists already investing billions into quantum ventures. We suggested everybody apply for a million, [but] some people came in and said they were going to do it for less, Altepeter said.
The unique value of a QBI award is that it gives the winning companies access to a DARPA-led team of quantum experts, pulled from both US government labs, including the famous Los Alamos, and federally funded research institutions. Their job is to act as independent testers, fresh eyes, and devil’s advocates, rigorously scrutinizing each participant’s quantum strategy.

Researchers from the U.S. Army Research Laboratory (ARL) and Lehigh University have developed a nanostructured copper alloy that could redefine high-temperature materials for aerospace, defense, and industrial applications.
Their findings, published in the journal Science, introduce a Cu-Ta-Li (copper-tantalum-lithium) alloy with exceptional thermal stability and mechanical strength, making it one of the most resilient copper-based materials ever created.
“This is cutting-edge science, developing a new material that uniquely combines copper’s excellent conductivity with strength and durability on the scale of nickel-based superalloys,” said Martin Harmer, the Alcoa Foundation Professor Emeritus of Materials Science and Engineering at Lehigh University and a co-author of the study. “It provides industry and the military with the foundation to create new materials for hypersonics and high-performance turbine engines.”
