Innovation improves the diagnosis of dizziness
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 have developed a new testing device using bone conduction technology, that offers significant advantages over the current tests. Hearing and balance have something in common. For patients with dizziness, this relationship is used to diagnose issu...
Graphene coating can kill bacteria on implants
A tiny layer of graphene flakes becomes a deadly weapon and kills bacteria, stopping infections during procedures such as implant surgery. This is the findings of new research from Chalmers University of Technology, Sweden, recently published in the scientific journal Advanced Materials Interfaces. Operations for surgical implants, such as hip and knee replacements or dental implants, have increased in recent years.
Superconductor may develop the quantum computers of the future
With their insensitivity to decoherence what are known as Majorana particles could become stable building blocks of a quantum computer. The problem is that they only occur under very special circumstances. Now researchers at Chalmers University of Technology have succeeded in manufacturing a component that is able to host the sought-after particles. Researchers throughout the world are struggling to build a quantum computer.
Nanoparticle mapping paves the way for better nanotechnology
Researchers at Chalmers University of Technology and the Technical University of Denmark have developed a method that makes it possible to map the individual responses of nanoparticles in different situations and contexts. The results pave the way for better nanomaterials and safer nanotechnology and were recently published in the journal Nature Communications.
Gamma rays will reach beyond the limits of light
Researchers have discovered a new way to produce high energy photon beams. The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today's technique. The obtained energy is a billion times higher than the energy of photons in visible light. These high intensity gamma rays significantly exceed all known limits, and pave the way towards new fundamental studies.
Fungi have immense potential for next-gen antibiotics
Fungi are a potential goldmine for the production of pharmaceuticals. This is shown by researchers at Chalmers University of Technology, who have developed a method for finding new antibiotics from nature's own resources. The findings - which could prove very useful in the battle against antibiotic resistance - were recently published in the journal Nature Microbiology. Antibiotics have saved millions of lives since ...
Mediating sensations via osseointegrated prostheses
A study has found that people with a prosthesis attached directly to their skeleton can hear by means of vibrations in their implant. This sound transmission through bones is an important part of osseoperception - sensory awareness of the patient's surroundings provided by their prosthesis. The discovery sheds new light on the tactile and auditory perception of humans and can be used to develop improved prostheses.
AR helps patients with chronic phantom limb pain
Dr Max Ortiz Catalan at Chalmers University of Technology has developed a novel method of treating phantom limb pain using machine learning and augmented reality. This approach has been tested on over a dozen of amputees with chronic phantom limb pain who found no relief by other clinically available methods before. The treatment reduced their pain by approximately 50%, reports a clinical study published in The Lancet.
Bendable electronic paper displays whole colour range
Less than a micrometre thin, bendable and giving all the colours that a regular LED display does, it still needs ten times less energy than a Kindle tablet. Researchers at Chalmers University of Technology have developed the basis for a new electronic "paper". Their results were recently published in the high impact journal Advanced Materials.
Taming ions could improve future health care
A group of researchers at Chalmers University of Technology has discovered a completely new way of using lasers to accelerate ion beams. In time, the new technique could possibly give more people access to advanced cancer treatment. The results were recently published in the high impact journal Physical Review Letters. Advanced ion technology may in some cases be used to treat otherwise inoperable tumors, such as brain tumors.
Tools boost computing energy efficiency
A European research project led by Chalmers University of Technology has launched a set of tools that will make computer systems more energy efficient – a critical issue for modern computing. Using the framework of the project programmers has been able to provide large data streaming aggregations 54 times more energy efficient than with standard implementations.
Graphene provides simple solution for silicon photodetection
As an important step towards graphene integration in silicon photonics, researchers from the Graphene Flagship have published a paper which shows how graphene can provide a simple solution for silicon photodetection in the telecommunication wavelengths. Published in Nano Letters, this research is a collaboration between the University of Cambridge (UK), The Hebrew University (Israel) and John Hopkins University (USA).
"Ultimate" project to produce ultra-efficient aero engines
The EU is investing over EUR 3 million in innovative aero-engine technologies in the three-year "Ultimate" project, short for "Ultra Low emission Technology Innovations for Mid-century Aircraft Turbine Engines". The project targets radical concepts for new aero engines, in line with the EU's long-term emissions reduction target for 2050. The project is being presented at a conference in South Korea.
High-entropy alloys convert waste heat to electricity
An interdisciplinary project at Chalmers has found that a special class of material – high-entropy alloys – can open the door to efficient heat recycling. Boosting energy efficiency is an important element of the transition to a sustainable energy system. There are big savings to be made. For example, less than half the energy content of diesel is actually used to power a diesel truck. The rest is lost, mostly in the form of heat...
Evolution inspires the development of driverless truck
Researchers at Chalmers University of Technology are finding inspiration in evolution's biological counterparts in the development of a driverless truck. The first public demonstration of the vehicle will take place on a Dutch motorway on 28 May. That's when the truck will take part in a competition for autonomous vehicles, within the framework of an EU project called the Grand Cooperative Driving Challenge.
Beating the diffraction limit with nanoantennas
Plasmonic nanoantennas are among the hot topics in science at the moment because of their ability to interact strongly with light, which for example makes them useful for different kinds of sensing. But matching their resonances with atoms, molecules or so called quantum dots has been difficult so far because of the very different length scales involved.
Functional packaging with less material
Much of the food sold in our grocery stores are packaged to avoid that substances like oxygen get in contact with the food and decompose it. It is of great importance to know which parameters that decide the permeability of the material. Within the competence center SuMo BIOMATERIALS at Chalmers researchers are developing materials with optimised properties.
Project to combine 5G with manufacturing technologies
Aiming to increase the sustainable competitiveness of Swedish industry, Chalmers University, Ericsson and SKF have announced the launch of 5G Enabled Manufacturing (5GEM), a two-year project to combine 5G with manufacturing technologies.
You're an atom; I'll bet you think this is about you
Researchers at Chalmers University of Technology have found that an artificial atom positioned in front of a mirror will survive up to ten times longer than normal.
