Scanning Tunneling Microscopy: Revealing New Characteristics of Complex Oxide Surfaces

A novel combination of microscopy and data processing has given researchers at the Department of Energy's Oak Ridge National Laboratory an unprecedented look at the surface of a material known for its unusual physical and electrochemical properties. The research team led by ORNL's Zheng Gai examined how oxygen affects the surface of a perovskite manganite, a complex material that exhibits dramatic magnetic and electronic behavior. The new avenue to understand surface behavior could benefit researchers who are interested in using a wide range of correlated oxide materials for applications such as solid fuel cells or oxygen sensors.

Medical Imaging: New Imaging Agent Provides Better Picture of the Gut

A multi-institutional team of researchers has developed a new nanoscale agent for imaging the gastrointestinal (GI) tract. This safe, noninvasive method for assessing the function and properties of the GI tract in real time could lead to better diagnosis and treatment of gut diseases. Results have been published online in Nature Nanotechnology.

Imaging Polarization Charges Using Charge Gradient Microscopy

Polarization charges in ferroelectric materials are screened by equal amounts of surface charges with opposite polarity under ambient conditions. Researchers from the Center for Nanoscale Materials, Argonne's Nanoscience & Technology and Materials Science divisions, and Tohoku University have shown that scraping, collecting, and quantifying surface screen charges reveals the underlying polarization domain structure at high speed, a technique dubbed charge gradient microscopy (CGM).

Reconstructing an Animal’s Development Cell by Cell

Advances in imaging technology are transforming how scientists see the cellular universe, showing the form and movement of once grainy and blurred structures in stunning detail. But extracting the torrent of information contained in those images often surpasses the limits of existing computational and data analysis techniques, leaving scientists less than satisfied.

New Simple Setup for X-Ray Phase-Contrast

X-Ray phase-contrast imaging can provide high-quality images of objects with lower radiation dose. But until now these images have been hard to obtain and required special X-Ray sources whose properties are typically only found at large particle accelerator facilities. Using a laboratory source with unprecedented brightness, scientists from the Technische Universität München (TUM), the Royal Institute of Technology in Stockholm (KTH) and University College London (UCL) have demonstrated a new approach to get reliable phase contrast with an extremely simple setup.

X-Ray Diffraction Reveals 3D Structure of RNAi Microsponges

Macromolecular complexes composed of self-assembling proteins and nucleic acids hold promise for a wide range of applications, including drug delivery, sensing and molecular electronics. Scientists have developed a broad array of x-ray scattering techniques for characterizing the shape and surface morphology of these complexes, but probing their internal structure remains a challenge. Changyong Song and colleagues from the RIKEN SPring-8 Center and RIKEN Advanced Institute for Computational Science have now devised a structural analysis scheme based on complementary advanced x-ray techniques that has allowed them to peer inside an RNA macromolecular complex for the first time. Results were published in Nature Communications.
