Light in science and technology

Researchers in this strong research environment want to take advantage of all the possibilities that light offers. They want to understand its properties, but also produce and use light in new and exciting ways.

The number of applications that utilize light in some form has increased rapidly during the most recent decades. Metrology, environmental monitoring and medical treatment are just a few examples of its area of application. Not to mention lighting. Which many mainly associate with light.

Researchers in this strong environment have developed an entirely new type of lighting component with the help of the super material graphene. It is cheap to produce and completely recyclable. The results could lead to bendable display monitors and glowing wallpaper. There are also plans to reverse the process and allow the component to be an energy source, a solar cell.

Laser light provides knowledge on urinary tract infections

Other researchers use laser-based methods in order to measure environmental toxins in emissions and exhausts. Laser light is also used like optical tweezers to catch and move cells and bacteria. The technology provides knowledge about the mechanisms, behind for example, urinary tract infections. Other researchers are working to produce new, interesting materials called carbon nanotubes. An important part of the research is about understanding how light works in a fundamental way. The researchers are looking for models that can explain what happens when light interacts with matter and how light is emitted from matter. This detailed knowledge about light can also give clues for future applications.

Umeå physicists make environmentally-friendly lighting with 'Nobel' material

This year's Nobel Laureates in Physics work with graphene, a form of carbon that is not only the thinnest, but the strongest ever. With the help of this super material, physicists at Umeå University have produced a new type of lighting component that will make lighting cheap and fully recyclable. Read more
