The electronic data connections within and between microchips are increasingly becoming a bottleneck in the exponential growth of data traffic worldwide. Optical connections are the obvious successors but optical data transmission requires an adequate nanoscale light source, and this has been lacking. Scientists at Eindhoven University of Technology (TU/e) now have created a light source …
China’s rapid nuclear expansion will result in it overtaking the U.S. as the nation with the largest atomic power capacity by 2026, according to BMI Research. The world’s second biggest economy will almost triple its nuclear capacity to nearly 100 gigawatts by 2026, making it the biggest market globally, analysts said in a note dated …
The Wall Street Journal indicates a forthcoming report from the US Government Accountability Office focuses most closely on issues with turbopumps in SpaceX’s Falcon 9 rocket. The report has found a “pattern of problems” with the turbine blades within the turbopumps, which deliver rocket fuel into the combustion chamber of the Merlin rocket engine. Some …
Most batteries are composed of two solid, electrochemically active layers called electrodes, separated by a polymer membrane infused with a liquid or gel electrolyte. But recent research has explored the possibility of all-solid-state batteries, in which the liquid (and potentially flammable) electrolyte would be replaced by a solid electrolyte, which could enhance the batteries’ energy …
There is an improved build strategy for the second Gerald R. Ford aircraft carrier. The Kennedy carrier (CVN-79)is being built using more modular construction, a process where smaller sections of the ship are welded together to form large structural units, equipment is installed, and the large units are lifted into the dry dock using the …
Developing efficient photoreversible color switching systems for constructing rewritable paper is of significant practical interest owing to the potential environmental benefits including forest conservation, pollution reduction, and resource sustainability. Here we report that the color change associated with the redox chemistry of nanoparticles of Prussian blue and its analogues could be integrated with the photocatalytic …
The quantity and quality of satellite-geodetic measurements of tectonic deformation have increased dramatically over the past two decades improving our ability to observe active tectonic processes. We now routinely respond to earthquakes using satellites, mapping surface ruptures and estimating the distribution of slip on faults at depth for most continental earthquakes. Studies directly link earthquakes …
Until now, the high cost of graphene production has been the major roadblock in its commercialiZation. Previously, graphene was grown in a highly-controlled environment with explosive compressed gases, requiring long hours of operation at high temperatures and extensive vacuum processing. Australian CSIRO scientists have developed a novel “GraphAir” technology which eliminates the need for such …
The microwave trapped ion universal quantum computer design work features a new invention permitting actual quantum bits to be transmitted between. individual quantum computing modules in order to obtain a fully modular large-scale machine capable of reaching nearly arbitrary large computational processing powers. Previously, scientists had proposed using fibre optic connections to connect individual computer …
Of the three types of Lockheed Martin’s F-35 Joint Strike Fighter, only the US Navy’s carrier-launched F-35C is at risk of being replaced by Boeing’s F-18 Super Hornet, the Marine Corps’s top pilot said today. It’s not on the table to substitute Hornets for either the land-based F-35A variant or the vertical-takeoff-and-landing F-35B, Lt. Gen. …
Lockheed Martin and the United States Air Force have been working on improving the performance of the F-22 Raptor’s stealth coatings. While the Raptor is by far the most capable air superiority fighter ever built, its Achilles’ Heel since it entered service has been maintenance. The F-22’s sensitive radar absorbent coatings have proven to be …
