The U.S. Army has awarded a $20 million a year contract to a California-based drone manufacturer, named Skydio, as part of its efforts to move away from foreign-made and commercially available off-the-shelf drones. Skydio revealed in a press release that it would supply its X2D drones for the U.S. Army’s Short Range Reconnaissance (SSR) Program.

With an aim to equip its soldiers with rapidly deployable aerial solutions that can conduct reconnaissance and surveillance activities over short ranges, the Army’s SSR program has been considering small drones for some time now. More than 30 vendors submitted their proposals to the Army, and five finalists were shortlisted for rigorous testing.

The Drive accessed a federal contract from 2017 that listed the minimal specifications of the SSR program which include a flight time of 30 minutes, a range of 1.86 nautical miles (3 km), and the ability to tolerate winds up to 15 knots. With the singular purpose of reconnaissance, the drone does not need to have swappable payloads but it should support mapping missions and the ability to geotag imagery.

IBM has just announced a partnership with the Government of Quebec to create the Quebec-IBM Discovery Accelerator in Bromont, Quebec. The accelerator will focus on using quantum computing, Artificial Intelligence (AI), and High-Performance Computing (HPC) to develop new projects, business/scientific/academia collaborations, and skills-building initiatives in research areas including energy, life sciences (genomics and drug discovery), new materials development, and sustainability. This is the fourth such center that IBM has announced. The three previously announced partnerships are with Cleveland Clinic, the University of Illinois Urbana-Champaign, and the UK’s Science and Technology Facilities Council Hartree Centre. IBM’s formal mission statement for these Discovery Accelerators is: “Accelerate scientific discovery and societal impact with a convergence of AI, quantum, and hybrid cloud in a community of discovery with research, academic, industry, startup, and government organizations working together.” IBM’s formal mission statement for these Discovery Accelerators is:

In addition, the company has developed individual mission statements for each of the four Discovery Accelerators:

The strongest part of a tree lies not in its trunk or its sprawling roots, but in the walls of its microscopic cells.

A single wood cell wall is constructed from fibers of cellulose—nature’s most abundant polymer, and the main structural component of all plants and algae. Within each fiber are reinforcing , or CNCs, which are chains of organic polymers arranged in nearly perfect crystal patterns. At the nanoscale, CNCs are stronger and stiffer than Kevlar. If the crystals could be worked into materials in significant fractions, CNCs could be a route to stronger, more sustainable, naturally derived plastics.

Now, an MIT team has engineered a composite made mostly from cellulose nanocrystals mixed with a bit of synthetic polymer. The organic crystals take up about 60 to 90 percent of the material—the highest fraction of CNCs achieved in a composite to date.

Silicon Valley hydrogen fuel cell innovator Hypoint has inaugurated a new UK unit intended to speed development of its air-cooled aviation power technology, and ready it to supply zero-carbon power to next-generation aircraft like electric takeoff and landing vehicles (eVTOL) as they prepare to launch services.

HyPoint’s tech uses compressed air for both cooling and oxygen supplies delivered to its fuel systems, which are lighter, less polluting, have longer lifespans, and enable seven times more flight capacity than lithium-ion and other chemical batteries. Those attributes are luring developers of existing, new drone, and eVTOL craft to give emerging hydrogen cell products serious consideration as drivers of their vehicles – especially as the world seeks to reduce its carbon output. In 2018, aviation sector’s share of global CO2 emissions was 2.5%.

A team of researchers from the University of Surrey’s Advanced Technology Institute (ATI) and the Federal University of Pelotas (UFPel), Brazil, has developed a new type of supercapacitor that can be integrated into footwear or clothing, an advance with applications in wearables and IoT (Internet of Things) devices.

A supercapacitor is an electricity storage device, similar to a battery, but it stores and releases electricity much faster.

The researchers have devised a novel method for the development of flexible supercapacitors based on carbon nanomaterials. The new method, which is cheaper and less time-consuming to fabricate, involves transferring aligned carbon nanotube (CNT) arrays from a silicon wafer to a polydimethylsiloxane (PDMS) matrix. This is then coated in a material called polyaniline (PANI), which stores energy through a mechanism known as pseudocapacitance, offering outstanding energy storage properties with exceptional mechanical integrity.
