Using lidar to measure the biodiversity of insects in the Taï rainforest

Published 25 February 2023 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

Soot particles - the remnants of incomplete combustion

Published 21 March 2023 Candle light (left figure) emitting yellow light which originates from hot soot particles, such as the one shown in the right figure. 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 par

Use lasers to see if your lungs are working

Published 29 March 2023 Here, a wild boar lung is used as a model similar to the lungs of a human child. A diode laser is used to check if the lung is filled with air. 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 th

Quantitative and qualitative measurements of aerosol soot using laser-based techniques

Published 19 April 2023 Detecting aerosol soot using Online Raman spectrosopy with a multi-pass configuration (Taken by Kim Cuong Le) 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. Soo

Ammonia as a fuel and hydrogen carrier

Published 20 April 2023 Turbulent ammonia flame. 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

Hydrogen operation in Siemens industrial gas turbines

Published 20 April 2023 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 pow

A method for measuring the healing after surgery

Published 21 April 2023 Esophagus cancer is treated with surgery by stitching the upper stomach together with the healthy part of the esophagus. An optical fiber can send light down the esophagus to look for problems occurring after the surgery. 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 h

Lasers will help us discover the fuels of tomorrow

Published 21 April 2023 Lasers can be used to look inside a flame and tell us what happens when things burn. 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

Improving food spray-drying with Tetra-Pak

Published 21 April 2023 Hollow-cone spray illuminated using a laser with a stripy structure (lines seen on the left edge). 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 ha

Backward lasing – a breakthrough for remote sensing

Published 24 April 2023 This video shows backward and forward lasing signals from oxygen atoms in a flame recorded in real time. The forward lasing signal is stronger, but of limited diagnostic value. 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,

Kläderna får en egen identitet

Publicerad 26 maj 2023 Harini Wijerathne och Dimitra Logotheti. Foto: Future by Lund. I framtiden kommer våra kläder att innehålla en tagg som vi kan skanna för att få information. På så vis kan vi få se hur plaggen är producerade, var vi kan få dem lagade och hur de kan återvinnas. Kanske kan vi till och med se vem som tidigare har burit plagget eller ges möjlighet att hyra ut det. Under våren st
