Raman Spectroscopy News and Research

RSS

In Raman spectroscopy, a laser is used to irradiate a sample. Almost all of the light is scattered in an elastic manner, meaning no change in energy occurs. However, a small percentage of light is scattered in an inelastic manner, known as Raman scattering. This process was first observed by Indian scientist Sir Chandrashekhara Venkata Raman in 1928.

Ancient bones and modern study methods add up to better science

Bone is a material that is essential for the study of humans in long-ago times. More precisely, the collagen, or fibrous tissue, which provides the groundwork for these bones, is required for radiocarbon dating of the fossil, as well as studies on ancient diet and the protein composition of older humans.

'MasSpec Pen' could help distinguish between cancerous and healthy tissue during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur.

Empa researchers reveal how steam causes severe burns

Whether working with steam pipes or in the kitchen: When boiling hot steam hits the skin, it will quickly cause burns. Firefighters are also at risk - due to their own sweat: If it evaporates under the heavy protective clothing in the heat of the fire and cannot escape, it condenses on the cooler skin and burns it.
