May 12 2021 X-ray ptychography has recently opened up applications across physical and life sciences at large-scale synchrotron facilities such as the UK’s Diamond Light Source, by producing quantitative phase images with the highest possible spatial resolutions (10’s nm) – going well beyond the conventional limitations of the available X-ray optics. Now an international collaboration of scientists has demonstrated for the first time how the technique of high-resolution phase contrast diffraction imaging can be performed with small-scale laboratory sources. The t...

Bringing High-Resolution X-Ray Imaging to the Laboratory May 12, 2021• Physics 14, s63 Researchers have scaled down x-ray ptychography—a high-resolution imaging technique that used to require large, expensive facilities—for use in the lab. D. J. Batey D. J. Batey × X-ray ptychography is a powerful new technique that uses the quantitative phase information in transmitted radiation to create nanometer-resolution images. Researchers have applied the method to image everything from biological tissues to archaeological artifacts to semiconductor nanostructures, but until now, the i...

share: This news release, originally issued by Diamond Light Source, describes a template for how to develop directly-acting antivirals that would combat COVID-19. The study focused on a specific part of the Nsp3 gene that SARS-CoV-2 uses to suppress the host cell’s natural antiviral response. Researchers from the University of California used the Highly Automated Macromolecular Crystallography (AMX) and the Frontier Microfocusing Macromolecular Crystallography (FMX) beamlines at the National Synchrotron Light Source II (NSLS-II) to characterize the molecular structure of proteins invo...

Specialism: Computational materials science Membership classification: MRSC     A thriving researcher, Jorge Ontaneda has published several papers in the field of surface science, with primary research interests in the electronic structure of metal-based interfaces for a wide variety of applications. But how he got into chemistry is a fortuity, as he originally wanted to study physics at university and beyond. “There wasn’t an option to study physics at my home university in Loja in Ecuador, so I had to choose something closely related, which was chemical engineering. I enjoyed the wo...
