New innovation improves the diagnosis of dizziness

New innovation improves the diagnosis of dizziness

Press Releases   •   Sep 10, 2018 07:01 BST

Half of over-65s suffer from dizziness and problems with balance. But some tests to identify the causes of such problems are painful and can risk hearing damage. Now, researchers from Chalmers University of Technology, Sweden, have developed a new testing device using bone conduction technology, that offers significant advantages over the current tests.

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

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.

​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

Graphene assembled film shows higher thermal conductivity than graphite film

​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.
