Fibre-optic transmission of 4000 km made possible by ultra-low-noise optical amplifiers

Press Releases   •   Jul 05, 2018 07:00 BST

​Researchers from Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, have demonstrated a 4000 kilometre fibre-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers. This is a reach improvement of almost six times what is possible when using conventional optical amplifiers. The results are published in Nature Communications.

Sweden invests 1 billion SEK in testbed for electromobility

Press Releases   •   Jun 29, 2018 09:31 BST

RISE (Research Institutes of Sweden), and Chalmers University of Technology have now begun, with support from the Swedish government, the establishment of a Swedish testbed for electromobility. Overall, contributions from the government, and the industrial partners CEVT, Scania, Volvo Cars and Volvo Group, enable an investment of 1 billion Swedish krona for the testbed.

How smart technology gadgets can avoid speed limits

Press Releases   •   Jun 28, 2018 07:00 BST

​Speed limits apply not only to traffic. There are limitations on the control of light as well, in optical switches for internet traffic, for example. Physicists at Chalmers University of Technology now understand why it is not possible to increase the speed beyond a certain limit – and know the circumstances in which it is best to opt for a different route.

Graphene assembled film shows higher thermal conductivity than graphite film

Press Releases   •   Jun 21, 2018 11:05 BST

​Researchers at Chalmers University of Technology, Sweden, have developed a graphene assembled film that has over 60 percent higher thermal conductivity than graphite film – despite the fact that graphite simply consists of many layers of graphene. The graphene film shows great potential as a novel heat spreading material for form-factor driven electronics and other high power-driven systems.

Swedish receiver to capture cosmic waves in the world's largest radio telescope

Press Releases   •   Jun 21, 2018 08:00 BST

Just arrived in South Africa, Chalmers’ most advanced radio receiver is Sweden's main contribution to the record-breaking telescope SKA (Square Kilometre Array). The advanced prototype, now being tested in the Karoo Desert, is not only shiny and new. It’s also an important step towards a radio telescope that will challenge our ideas of time and space.

Ground-breaking discoveries could create superior alloys with many applications

Press Releases   •   Jun 19, 2018 08:01 BST

Many current and future technologies require alloys that can withstand high temperatures without corroding. Now, researchers at Chalmers University of Technology, Sweden, have hailed a major breakthrough in understanding how alloys behave at high temperatures, pointing the way to significant improvements in many technologies. The results are published in the highly ranked journal Nature Materials.

Multiple lasers could be replaced by a single microcomb

Press Releases   •   Jun 12, 2018 07:00 BST

​Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth and to squeeze in an increasing amount of digital data. Researchers have now shown that all these lasers can be replaced by a single device called a microcomb.

Advanced biofuels can be produced extremely efficiently, confirms industrial demonstration

Press Releases   •   May 21, 2018 07:00 BST

Researchers from Chalmers University of Technology, Sweden, have developed new technologies that can be used to convert industrial plants to produce fossil-free heat, electricity, fuel, chemicals and materials. The technical potential is enormous – using only Sweden's currently existing power plants, renewable fuels equivalent to 10 percent of the world's aviation fuel could be produced.

Sweden's top facility for new smart industry jobs opens its doors

Press Releases   •   May 09, 2018 07:00 BST

On the 8th of May, the doors were opened to the Stena Industry Innovation Laboratory (SII-Lab) at Chalmers campus Lindholmen, Sweden – a 1000 square meter test-lab for digitalisation and future jobs in industry. Production researchers Johan Stahre and Åsa Fast-Berglund invite everyone to engage – young people, students, researchers and companies!

Flares in the universe can now be studied on earth

Press Releases   •   May 02, 2018 07:01 BST

Solar flares, cosmic radiation, and the northern lights are well known phenomena. But exactly how their enormous energy arises is not as well known. Now, physicists at Chalmers University of Technology, Sweden, have discovered a new way to study these spectacular space plasma phenomena in a laboratory environment.
