Graphene sieve turns seawater into drinking water

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved. New research demonstrates the real-world potential of providing clean drinking water for millions of people who struggle to access adequate clean water sources. Graphene-oxide membranes developed …

DARPA wants engineers to rethink conventional approaches for breakthrough Spectrum Management

DARPA earlier this month hosted the Battle of the ModRecs—a low-key competitive opportunity for engineers with a penchant for antennas and algorithms to test their skills in modulation recognition. “We’re looking to push modulation recognition out of its comfort zone,” said DARPA program manager Tom Rondeau. “We want scientists and engineers to rethink conventional approaches …

Amazon, Alibaba will use self driving vehicles, robotics, 3d printing and AI to compete on same day delivery

Amazon, which currently charges a $99 annual fee for two-day deliveries under its “Prime” service, will eventually offer two-tier pricing for delivery services, Jindel said. One will be a “Gold Prime” membership costing $199 to $249 a year that covers next-day deliveries, the other a platinum membership for $399 a year that includes same-day deliveries. …

Intel and Taiwan Semiconductor remain confident of scaling CMOS to 3 nanometers and maybe beyond

Intel remains confident about scaling CMOS and extending Moore’s law beyond 2024 Someday we may reach a physical limit. But Intel does not see that point on their horizon. 1990, when the features on the wafer were the same size as the wavelength of the light we used to print them: 193 nm. Physics was …

China working on reusing rocket stages and will try to use parachutes and airbags to recover stages

China is developing a rocket stage and engine recovery system at the China Academy of Launch Vehicle Technology in Beijing. It uses using a set of multiple parachutes, which are stored in the first stage of the rocket, which is released from the rest of the craft before it burns its way through the Earth’s …

Navy focused on UAV just for refueling for faster development and deployment

Currently the US Navy refuels its carrier aircraft with its Super Hornet fleet. The tanking mission accounts from anywhere from 25 to 30 percent of Super Hornet sorties, further exacerbating the ongoing tactical aviation shortfalls in the service. That demand – in part – is pushing the Navy to get a tanking UAV into service …
