Aalto University

Researchers at the University of Aalto, Finland have broken the efficiency record for black silicon solar cells a type of cell that can gather sunlight even from tight angles by almost four percent.

Rolls-Royce, VTT Technical Research Centre of Finland, and Aalto University are expanding on their ideas for a virtual bridge that could soon lead to a future where the line between manned and robotic ships becomes completely blurred. Combining automated ship systems and constant high-data level communications, it's part of what Rolls-Royce see as the "next major transition for the shipping industry." Read More
Horatio Hornblower meets Jean-Luc Picard on the ship’s bridge of 2025 as Finnish applied research organization VTT and Rolls-Royce present their vision of seafaring ten years from now. Presented in 3D animation videos that projects current technology to the near future, the study shows a world where ship captains call on heads-up displays and high-tech workstations turn the bridge into an augmented reality command and control system.

Researchers at Aalto University in Finland have discovered a novel way to write and present information using only water and air. They used the water-repelling properties of the lotus leaf as inspiration for an experiment with a superhydrophobic (“water-repelling”), dual-scale surface that allows the writing, erasing, rewriting and storing of optically displayed information in plastrons related to different length scales. The research was carried out in partnership with the Nokia Research Center and University of Cambridge and was led by Dr. Robin Ras at Aalto University. Read More

Smart phones are techno wonders, and they are also energy guzzlers, which is not a problem for people living in the developed world. However, their high energy requirements has stymied the adoption of mobile internet services in developing countries where mobile internet can be a real lifeline. In Africa, for example, few people can access the internet from a wired connection but 90 percent of the population lives in areas with mobile phone network coverage. There’s one problem though. Access to the power grid in Africa is limited. Read More

While fuel cells show a lot of promise for cleanly powering things such as electric cars, there’s something keeping them from being more widely used than they currently are – they can be expensive. More specifically, the catalysts used to accelerate the chemical processes within them tend to be pricey. Work being done at Finland’s Aalto University, however, should help bring down the cost of fuel cells. Using atomic layer deposition (ALD), researchers there are making cells that incorporate 60 percent less catalyst material than would normally be required. Read More
Fans of the original film in the Terminator franchise will recall how various bits of data were shown to be overlaid on the cyborg's vision - in particular, they might remember the list of possible responses that could be used when someone was angrily knocking on its door (for those who don't remember, its chosen response wasn't very polite). Such augmented vision systems are now a little closer to reality, thanks to work being done by a team of scientists at the University of Washington and Aalto University, in Finland. They have created a contact lens that displays information, which is visible to the wearer. Read More
Many hybrid cars feature regenerative braking – they harness the energy generated when they brake, and store it in the battery for later use. This helps maximize the amount of time that the car can run on one charge. One can’t help but wonder, then, how much energy could be harvested from heavy-duty construction, mining and agricultural machines, as they go about their business. A group of researchers from Finland’s Aalto University decided to find out, and reportedly ended up cutting those machines’ fuel consumption by 50 percent. Read More
