Schwartz’s presentation about the future of BES was followed by overviews of activities at NSLS-II and CFN during the past year and coming years. Both facility directors provided insights into what users can expect, and they conveyed their excitement at the continuing progress at NSLS-II and CFN.

Enabling excellent research capabilities for nanostructures

Chuck Black, Director of CFN, welcomed the attendees of this year’s meeting on behalf of CFN, and offered them a brief overview of his facility. He showed the history of user growth at CFN over the last 10 years and explained that CFN’s mission is to offer world-class research instrumentation and deliver impactful science to move the field of nanoscience forward.

“The combination of state-of-the-art instrumentation with a talented staff dedicated to supporting user science is essential to CFN’s success.  Users value the experience of working with top caliber scientists and using world-class nanoscience equipment; our job is to help them achieve their goals. There are no other facilities like these in the world,” Black said.  

Black also spoke about the diverse and impactful science that is carried out by CFN staff members including materials for capture of rare, radiological gases, DNA scaffolds for protein crystallization, and real-time electron tomography. In addition to their own research, CFN staff members assisted a wide variety of user research including colorful polymer solar cells, amorphous iron-based nano-coatings on steel and investigations of lithium-ion battery anodes. Black discussed that three strategic themes are based on CFN facility strengths and scientific accomplishments: self-assembled nanomaterials by design, the design and study of nano-architectures and the characterization of nanomaterials in operando. He highlighted that CFN’s new capabilities including nanoscale 3D printing and advanced x-ray scattering are well-aligned with these themes and that CFN will continue to deliver forefront, essential nanoscience capabilities to the worldwide research community and impactful science in the next years.  

Science highlights and brilliant plans

Following Black’s presentation, John Hill, Director of NSLS-II, welcomed the attendees and presented last year’s statistics that demonstrated the reliability and success of NSLS-II as a user facility. Hill pointed out that the user program was growing rapidly together with the number of beamlines ready for general user proposals. NSLS-II will have 28 beamlines operating by the end of the year.

“It is an exciting time at NSLS-II and the Users’ meeting reflects that,” Hill said. “The machine is performing beautifully, the user program is ramping up quickly and the science is coming out. This last one is particularly exciting as experiments are being carried out at NSLS-II that could not be done anywhere else in the world. Our staff and users are using the ultra-high brightness of NSLS-II to study dynamic electronic processes, to solve structures of ever smaller crystals and to image chemical processes on the nanoscale, all for the first time. It is great to see everyone here, all sharing that excitement!”
