NanoLund affiliated researcher recieves funding to develop a new microscope.
Pablo Villanueva Perez, associate senior lecturer in Synchrotron Radiation Physics, will develop a completely new X-ray microscope to improve the study and filming of different materials in 3D. Today this is done using microtomography (μCT) by irradiating a rotating sample with X-rays so that it is struck from different directions. In recent years the technology has been refined in step with enhancements in X-ray sources, detectors and 3D algorithms. However, one problem remains. The samples must still be rotated, which may result in them being damaged or, in the worst case, destroyed. Therefore, Pablo Villanueva Perez and a research team are to develop a new X-ray microscope that does not require rotating samples. This is to be done by splitting and manipulating X-ray beams into a number of angled light sources that illuminate the samples at the same time.
“I will use the new microscope to study fundamental processes in cellulose, which is a renewable material. I hope in the long term to develop an eco-friendly material that can replace plastic”, says Pablo Villanueva Perez.
