Advance in sample environment allows simultaneous measurement of electronic properties, microstructure, and rheology in complex fluids

A team of researchers at the NCNR and University of Delaware have developed a Dielectric RheoSANS environment to simultaneously measure the electric, mechanical, and microstructural properties of complex fluids.   Their first application of the technique was to study carbon black slurries as they move through an electrochemical flow cell.

Carbon based nanocomposites have been proposed as electrically percolating  semi-solid flow battery electrodes.  For such an application, electrical conductivity must be maintained while the electrode is continuously pumped through an electrochemical flow cell. Under these conditions, it is highly desirable to maximize the conductivity of these suspensions while reducing their viscosity in order to minimize pumping losses.  To understand the link between these properties, a new tool has been developed at the NIST Center for Neutron Research, which allows measurement of the electrical, mechanical and microstructural response of carbon particles under arbitrarily complex deformations.

More information can be found in the NCNR 2016 annual report, as well as in a recently published article.

Neutrons zero in on the elusive magnetic Majorana fermion

From Oak Ridge National Laboratory:

Neutron scattering has revealed in unprecedented detail new insights into the exotic magnetic behavior of a material that, with a fuller understanding, could pave the way for quantum calculations far beyond the limits of the ones and zeros of a computer’s binary code.

A research team led by the Department of Energy’s Oak Ridge National Laboratory has confirmed magnetic signatures likely related to Majorana fermions—elusive particles that could be the basis for a quantum bit, or qubit, in a two-dimensional graphene-like material, alpha-ruthenium trichloride. The results, published in the journal Science, verify and extend a 2016 Nature Materials study in which the team of researchers from ORNL, University of Tennessee, Max Planck Institute and Cambridge University first proposed this unusual behavior in the material.

Science To Solve World Hunger: Neutron Research With Plants

From the Canadian Institute of Neutron Scattering (CINS):

University of Saskatchewan scientists use neutron beams to observe plant roots in soil to aid breeding of drought-resistant crops.

Dr. Emil Hallin, with the University of Saskatchewan’s Global Institute of Food Security (GIFS), and Dr. Paul Arnison, a biotechnology consultant, came to Canadian Nuclear Laboratories (CNL) with the goal of demonstrating the efficacy of imaging plants with neutron beams. The time, place and people are ripe – right now – to establish neutron imaging as a minimally invasive technique that can provide unprecedented information on how plants grow, especially with respect to two key areas: root architecture and water movement.

2017 National School on Neutron and X-Ray Scattering

The 19th National School on Neutron and X-Ray Scattering will begin on August 5th 2017.

From the school’s website:

“The main purpose of the National School on Neutron and X-ray Scattering is to educate graduate students on the utilization of major neutron and x-ray facilities. Lectures, presented by researchers from academia, industry, and national laboratories, will include basic tutorials on the principles of scattering theory and the characteristics of the sources, as well as seminars on the application of scattering methods to a variety of scientific subjects. Students will conduct short experiments at Argonne’s Advanced Photon Source and Oak Ridge’s Spallation Neutron Source and High Flux Isotope Reactor facilities to obtain hands-on experience for using neutron and synchrotron sources.”

CHRNS 2017 Summer School on the Fundamentals of Neutron Scattering

The twenty-third annual Center for High Resolution Neutron Scattering (CHRNS) Summer School will be held at the NIST Center for Neutron Research (NCNR), from June 19th to 23rd, 2017.

From the school’s website:

“The school will focus on techniques that employ long wavelength neutrons to achieve high energy resolution, enabling the study of dynamical processes over a wide range of time scales, from ~100 ns to ~1 ps. Participants will have the chance to use three of the following 5 neutron instruments: disk chopper spectrometer (DCS), backscattering spectrometer (HFBS), spin echo spectrometer (NSE), BT7 double focusing triple-axis spectrometer, the multi axis crystal spectrometer (MACS).

The course is targeted at those with little or no previous experience with neutron inelastic scattering methods. The combination of introductory lectures and training in scattering techniques will provide participants with a unique opportunity to become familiar with neutron scattering methods and their application to current research topics.”

International Conference on Neutron Scattering (ICNS) 2017

The International Conference on Neutron Scattering 2017 (ICNS 2017) will take place in Daejeon, Republic of Korea, at the Daejeon Convention Center from July 9th to 13th, 2017.

From the ICNS 2017 website:

“The ICNS 2017 will be the largest international platform for sharing and exchanging the latest exciting advances in neutron scattering science, which will bring together scientists from a wide range of disciplines including physics, biology, chemistry, materials science, engineering materials, earth science, neutron sources and instrumentations. The ICNS is held every four years cycling through Europe, America and Asia-Oceania regions. Previous ICNS includes ICNS2013 (Edinburgh, UK), ICNS2009 (Knoxville, US), ICNS2005 (Sydney, Australia), ICNS2001 (Munich, Germany), ICNS97 (Toronto, Canada), ICNS94 (Sendai, Japan), ICNS91 (Oxford, UK), ICNS88 (Grenoble, France), ICNS85 (Santa Fe, US), and ICNS82 (Hakone, Japan).”

2017 Joint Nanoscience and Neutron Scattering User Meeting at Oak Ridge National Laboratory

The SNS/HFIR User Group and CNMS User Group at Oak Ridge National Laboratory (ORNL) are holding a joint user meeting from July 31st to August 3rd 2017, at ORNL.  The main meeting days are August 1st and 2nd, which are flanked by two workshop days (July 31 and August 3rd).  Details can be found at the conference website.

Gordon Research Conference on Neutron Scattering 2017

The Gordon Research Conference (GRC): Structure and Dynamics of Materials on Many Length and Time Scales will be held at The Hong Kong University of Science and Technology, Hong Kong, China from August 6-11 2017.  The meeting will be held in conjunction with the “Neutron Scattering” Gordon Research Seminar (GRS).

From the GRC website:

“This GRC will be a forum for discussing how new neutron instrumentation is advancing our understanding of new materials – the materials that will help us address significant challenges and societal needs through the 21st century.

Neutron science impacts a broad range of materials and the GRC sessions will focus on these, including magnetic and superconducting materials, topological materials, polymeric and biological materials, as well as energy-related and engineering materials. Attention will focus on current and cutting edge research problems and how new neutron instrumentation can solve important problems. The Neutron Scattering GRC will also feature an associated GRS to address the needs of a large cohort of young neutron scientists.”
