Researchers fabricate arrays of atomically smooth iron-coated silicon pyramids with unusual magnetic properties
Ultra-small integrated circuits have revolutionized mobile phones, home appliances, cars, and other everyday technologies. To further miniaturize electronics and enable advanced functions, circuits must be reliably fabricated in three dimensions. Achieving ultrafine 3D shape control by etching into silicon is difficult, because even atomic-scale damage reduces device performance. Researchers at Nara Institute of Science and Technology (NAIST) have published a new study in Crystal Growth and Design in which they etched silicon to adopt the shape of atomically smooth pyramids. Coating these silicon pyramids with a thin layer of iron imparted magnetic properties that until now were only theoretical.
NAIST researcher and senior author of the study Ken Hattori is widely published in the field of atomically controlled nanotechnology. One focus of Hattori’s research is in improving the functionality of silicon-based technology.
“Silicon is the workhorse of modern electronics because it can act as a semiconductor or an insulator, and it’s an abundant element. However, future technological advances require atomically smooth device fabrication in three dimensions,” says Hattori.
Supercapacitors Challenge Batteries: Powerful Graphene Hybrid Material for Highly Efficient Energy Storage
A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries.
Usually, energy storage is associated with batteries and accumulators that provide energy for electronic devices. However, in laptops, cameras, cellphones or vehicles, so-called supercapacitors are increasingly installed these days.
Unlike batteries they can quickly store large amounts of energy and put it out just as fast. If, for instance, a train brakes when entering the station, supercapacitors are storing the energy and provide it again when the train needs a lot of energy very quickly while starting up.
Meet Airspeeder, the startup that wants to help bring flying cars to the market with high-speed air races
Airspeeder wants to be the “first electric flying car race,” its CEO told Insider. It also wants you to know flying cars are closer than you think.
The thorium-powered car: Eight grams, one million miles
A US company says it will have a nuclear-powered prototype vehicle on the road within two years.
Laser Power Systems from Connecticut is developing a method of propulsion that uses thorium to produce electricity to power a car engine.
Thorium is an element similar to uranium and because it is such a dense material it has the potential to produce massive amounts of heat.
According to Laser Power Systems CEO, Charles Stevens, just one gram of thorium produces more energy than 28000 litres of petrol. Mr Stevens says just eight grams of thorium would be enough to power a vehicle for its entire life.
Immortus solar sports car to offer unlimited range on sunny days
Circa 2015
If you’ve ever scanned the comments section on an electric car or bike article, you’ll be familiar with this complaint: “that’s not green, it’s just a coal-powered vehicle.” Well, not this one. The Immortus is an electric car built to generate its own power through some 7 sq m (75 sq ft) of solar photovoltaic paneling. You can charge its battery off the mains if you have to, but if conditions are sunny, the inbuilt solar panels alone will let you drive at more than 60 km/h (37 mph) for an unlimited distance.
The Immortus is based on solar race car technology with the project originally founded by Australia’s Aurora Solar Car Team, which has competed in a bunch of solar race events across the world. Hence the light weight and the shape of the Immortus, which combines maximal sun exposure with extreme aerodynamics, including covered wheels.
Unlike the solar racers, though, it’s designed to approach practicality on the road, with a 0–100 km/h (62 mph) time that will be less than seven seconds and a top speed over 150 km/h (93 mph). It’s also a two-seater with a modest luggage capacity for daily driving. Melbourne-based EVX Ventures, creators of the Immortus, even list fun as a priority, saying it should handle like a well-balanced sports car.
