Senior researchers and PhD students from the Semiconductor materials Division shared their

excitement about science and research with the pupils from Katedralskolan. In an introductory

lecture by Vanya Darakchieva and Olle Kordina, the youngsters learned about the properties and societal

impact of group-III nitrides, graphene and SiC. The young people also visited key labs and witnessed

growth runs and exciting experiments on materials characterization.

Thestudyhence,indicatesthatitistheinitialstagesoffibrilformationandfragmentsoftheamyloidfibrilsthataremosttoxictoneuronsandthatcurcuminacceleratedthisconversionstep.

Figure. Survival curves for ”Alzheimer flies” treated (dashed line) and those not treated with curcumin. The flies that were administered curcumin lived longer and were more active. The scientists identified an accelerated formation of amyloid plaque in the treated flies, which seemed to protect the nerve cells. On the right we see microscopic images of neurons (blue) and plaque (green) in the fruit fly’s brain. The study strengthens the hypothesis that a curcumin-based drug can contribute to toxic fibrils being encapsula-ted (bottom left of the figure).

There is a striking difference in both the rise time and the peak current value between the two modes. The pulsing frequency was constant (50 Hz), the pulse length was 300 μs, and the target diameter was 100 mm. The average discharge power was varied between 100 and 400 W.
