Dr. Benjamin Watts, PSI

Soft X-ray Spectroscopy and Microscopy of Organic Materials

Benjamin Watts is a beamline scientist at the PolLux scanning transmission soft X-ray spectro-microscope (STXM) specialising in the materials analysis of soft matter. He obtained a BSc (Professional) in Physics, with Honours, and a PhD in Physics from the University of Newcastle, Australia, before working as a post-doctoral researcher with North Carolina State University (permanently stationed at the Advanced Light Source, Berkeley) in the USA and then moving to PSI. Details of the interactions between soft X-ray light and organic materials has been a continuing theme throughout both his university research and later career.

The core of Benjamin Watts’ research involves the use of soft X-ray spectroscopy and microscopy of organic materials, especially near-edge X-ray absorption fine structure (NEXAFS or XANES) spectroscopy at the carbon K-edge and scanning transmission X-ray microscopy (STXM). C K-edge NEXAFS  provides spectral fingerprints corresponding to types of molecular bonding present in the sample material and so allows differentiation between organic materials based on their molecular structure. X-ray microscopy techniques such as STXM can then utilise this spectroscopy as a contrast mechanism to create quantitative nanoscale maps of materials properties such as  composition, molecular conformation and mass density. Of particular interest is the imaging  of nano-structures in conjugated polymer based electronic devices, such as OLED’s and polymer solar cells, which are creating revolutions in the digital display and energy industries. Benjamin Watts also has strong interest in developing novel data analysis methods, improved data collection and storage formats, and the programming of data analysis tools with graphical user interfaces, which each represent key facets of the dissemination of knowledge.

The Vinnova competence center FibRe started 2020 and is one of the largest research initiatives on new materials from the forest in Sweden. In FibRe, the partners from academia, industry and public sector combine their expertise to develop thermoplastic lignocellulose-based materials and the needed competence with specific focus on 

1) modification
2) advanced characterization
3) processing. 

All seminars are available to watch afterwards at Treesearch’s YouTube channel, where you also can find more other research seminars
