Inflatable space robots with integrated dielectric elastomer transducers (DETs)

Posted by in categories: bioengineering, robotics/AI, space

Researchers at the Auckland Bioengineering Institute and Technische Universit\xE4t Dresden have recently designed a new type of inflatable robot for space navigation. These robots, presented in a paper published in SPIE Digital Library, were created using dielectric elastomer transducers (DETs), which are essentially electrical capacitors made from soft rubbery materials.

“Current technology is limited by its mass and volume. It takes thousands of dollars to launch even a single kilogram into orbit,” Joseph Ashby, one of the researchers who carried out the study, told TechXplore. “Our research aims to replace or augment current technology with lighter smart-material replacements combined with inflatable structures.”

If they are integrated with inflatable structures, DETs could aid the development of soft and low-mass robots, which have high packaging efficiency and are easy to deploy. In fact, DETs deform when a voltage is applied to them, due to the Maxwell stress generated by the electric field.

Grapes on Mars? Georgia winemakers aiming high

Posted by in categories: climatology, space

Georgia is immensely proud of its ancient wine-making tradition, claiming to have been the first nation to make wine. Now it wants to be the first to grow grapes on Mars.

Nestling between the Great Caucasus Mountains and the Black Sea, Georgia has a mild climate that is perfect for vineyards and has developed a thriving wine tourism industry.

Now Nikoloz Doborjginidze has co-founded a project to develop grape varieties that can be grown on Mars.

A Jetsons future? Assessing the role of flying cars in sustainable mobility

Posted by in categories: sustainability, transportation

In the 1960s animated sitcom The Jetsons, George Jetson commutes to work in his family-size flying car, which miraculously transforms into a briefcase at the end of the trip.

A new study of the environmental sustainability impacts of flying cars, formally known as electric vertical takeoff and landing aircraft, or VTOLs, finds that they wouldn’t be suitable for a Jetsons-style short commute.

Scientists Discover Ancient ‘Cthulhu’ Fossil That Will Give You Nightmares

Posted by in categories: energy, food

O,.,0.


Despite its diminutive size, the creature still managed to pack a lot of nightmare fuel. Those 45 tentacles were used to snatch up food, creep along the ocean floor and scare off predators.

Oh, and those “tubes” also had their own armor.

Graphene coating could help prevent lithium battery fires

Posted by in categories: energy, engineering, transportation

Lithium batteries are what allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known, but so is their tendency to occasionally catch on fire—an occurrence known to battery researchers as “thermal runaway.” These fires occur most frequently when the batteries overheat or cycle rapidly. With more and more electric vehicles on the road each year, battery technology needs to adapt to reduce the likelihood of these dangerous and catastrophic fires.

Researchers from the University of Illinois at Chicago College of Engineering report that graphene—wonder material of the 21st century—may take the oxygen out of lithium battery fires. They report their findings in the journal Advanced Functional Materials.

The reasons catch fire include rapid cycling or charging and discharging, and in the battery. These conditions can cause the cathode inside the battery—which in the case of most lithium batteries is a lithium-containing oxide, usually lithium cobalt oxide—to decompose and release oxygen. If the oxygen combines with other flammable products given off through decomposition of the electrolyte under high enough heat, spontaneous combustion can occur.

New algorithm optimizes quantum computing problem-solving

Posted by in categories: business, computing, information science, particle physics, quantum physics

Tohoku University researchers have developed an algorithm that enhances the ability of a Canadian-designed quantum computer to more efficiently find the best solution for complicated problems, according to a study published in the journal Scientific Reports.

Quantum computing takes advantage of the ability of subatomic particles to exist in more than one state at the same time. It is expected to take modern-day computing to the next level by enabling the processing of more information in less time.

The D-Wave annealer, developed by a Canadian company that claims it sells the world’s first commercially available quantum computers, employs the concepts of quantum physics to solve ‘combinatorial optimization .’ A typical example of this sort of problem asks the question: “Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each and returns to the original city?” Businesses and industries face a large range of similarly complex problems in which they want to find the optimal solution among many possible ones using the least amount of resources.
