Seafaring drones are navigating Norway's fjords
While there are government-approved test sites for land-based autonomous vehicles in the US, so far there is only one official test site for their seafaring counterparts. Tucked away in Norway's Trondheim Fjord, the test site offers wide, open waters similar to a small sea, but with relatively low shipping traffic so there's less of a chance of a collision should one of the test vehicles go haywire. The site officially opened late last year, but thanks to the cluster of research institutions and businesses in the area, companies like Kongsberg Seatex, Marintek, Maritime Robotics and Rolls-Royce Marine have all flocked to the fjord to test their new robotic and autonomous technologies.
Antimicrobial silver coatings could be hindering your chemo
Hospitals around the world use a silver coating on their chemotherapy equipment, such as IV catheters, because the noble metal prevents microbial growth. However, it turns out that this germ killing coating could be damaging chemo drugs that flow over it and harming patients. A team of researchers from the Norwegian University of Science and Technology's (NTNU) Department of Physics revealed this effect in a study recently published in the journal 2D Materials. "We wanted to find potential problem sources in the tubes used in intravenous catheters...Chemotherapy drugs are active substances, so it isn't hard to imagine that the medicine could react with the silver," Justin Wells, associate professor of physics at NTNU, said in a statement.
New process for nanotube semiconductors could be graphene's ticket to primetime (video)
In many ways, graphene is one of technology's sickest jokes. The tantalizing promise of cheap to produce, efficient to run materials, that could turn the next page in gadget history has always remained frustratingly out of reach. Now, a new process for creating semiconductors grown on graphene could see the super material commercialized in the next five years. Developed at the Norwegian University of Science and Technology, the patented process "bombs" graphene with gallium, which forms droplets, and naturally arranges itself to match graphene's famous hexagonal pattern. Then, arsenic is added to the mix, which enters the droplets and crystallizes at the bottom, creating a stalk. After a few minutes of this process the droplets are raised by the desired height. The new process also does away with the need for a (relatively) thick substrate to grow the nanowire on, making it cheaper, more flexible and transparent. The inventors state that this could be used in flexible and efficient solar cells and light emitting diodes. We say forward the revolution.
