When you are cleaning your car with your high-pressure washer have you ever considered how it works? Well we have and to figure that out we need to see how the liquid looks like in 3D. As is seen in the video above we have 3D reconstructed the surface of a cone-like liquid using a technique developed at the division of combustion physics. This technique apply lasers and a single high-speed camera

Insects are essential to the natural world, playing a vital role in maintaining ecosystem processes and providing valuable ecosystem services. However, studying insect biodiversity has proven challenging and labor-intensive since current methods use manually emptied traps. We recognized the need for a powerful and efficient tool to study insect abundance and richness in forests. So we developed a

Probably you have looked into a candle light and been fascinated by the high intensity of the yellow light! Have you ever been thinking about the origin of this light? This brilliant light actually comes from nano-meter sized carbonaceous particles that we in daily life call soot. Soot particles emitted from a combustion process to the ambient air are black, but at flame temperatures 1500 - 2000 °

Did you know that lung complications are the most common cause of death for preterm infants, and that problems with lungs are one of the most serious complications that can happen when children are sedated for surgery? The aim of this project is to develop a way to measure the lung function in children who are treated in intensive care in the hospitals. We send infrared laser light into the body t

Soot can be emitted from both natural and anthropogenic sources, including mineral deposits, open forest fires, savanna burnings, biomass burning, residential burning, and fossil fuel combustion. It absorbs solar radiation and contributes to atmospheric heating. Soot nanostructures contain varying levels of toxic chemicals that can penetrate deep into the bodies of humans and animals, leading to r

The contribution of carbon dioxide emissions from combustion to global warming is well known. How can this be mitigated? One way is carbon-free combustion with hydrogen. But how about challenges with hydrogen handling, storage and distribution? Combustion of hydrogen (H2) can provide energy without net carbon dioxide emissions contributing to global warming. However, hydrogen is very flammable, ma

A gas turbine is a combustion engine that can convert fuel to mechanical power. This mechanical power can be used for producing electric power and generating thrust in a jet aircraft. We are all well familiar with climate change, global warming and the urgent need to reduce greenhouse gases. The use of hydrogen in the process industry, e.g., for steel production, in the power industry for electric

We are working in close collaboration with neuroscientists from the B.R.A.I.N.S unit at the Biomedical Center to develop techniques for 3D imaging of cleared mouse brain tissue. These techniques will assist their research on Parkinson’s and Alzheimer’s disease. Clearing of tissue have become increasingly popular within the neuroimaging community over the last decade, as it offers researchers the n

Our group works with medical laser diagnostics, specifically aimed at monitoring of oxygen in lungs using the GAs in Scattering Media Absorption Spectroscopy (GASMAS) technique. This has found successful application in the monitoring of the lung function for preterm infants, where careful monitoring of spatially distributed oxygen content can lead to optimal respiratory support and prompt detectio

Imagine you had to get surgery due to esophagus cancer. Initially, you seem to recover well, but suddenly you are rushed to emergency surgery. The wound has failed to heal and the inflammation has caused severe, life-threatening sepsis. What if this could have been prevented? What if your doctors could have seen the problem in the wound days before the severe problem occurred, and been able to fix

How can we stop global warming? Simple: we need to stop burning fossil fuels. Unfortunately, it is difficult to replace fossil fuels in all parts of society. In this project, we develop laser techniques that can help us understand the how energy is produced when different things burn, which will help developing new, clean biofuels. There are some areas in society where burning things is the best/e

Most milk powders you buy have been produced through spray drying. This means that the milk after some preprocessing is injected under high-pressure through a small hole into a warm room. Then almost instantly, the liquid evaporates leaving the powder. The final product now has a longer shelf life, lower transport weight and can be stored in room temperature. However it is a very energy consuming

Ever since it was invented in the 1960s, the laser has found new areas of use, and is today very useful in research, industry and society. In most laser applications, for example material processing, the laser can be placed very close to the area to be processed. However, there are many important application areas where this is problematic. For example, if you want to use the laser to study an are
