Investigation of porosity, texture, and deformation behavior using high energy X-rays during in-situ tensile loading in additively manufactured 316L stainless steel
A high-energy x-ray study of 316L stainless steel produced by laser powder bed fusion used x-ray tomography to understand porosity in the manufactured samples, and then observe the effect of these pores on the evolution of damage, texture, and strain when the materials are mechanically deformed.
Incommensurate charge order in a low-dimensional superconductor
A team lead by Sara Haravifard from Duke University has conclusively and directly identified the subtle charge density wave phase in TPT emerging below 12K. The CDW couples to the superconducting transition and is suppressed by pressure at a critical point that maximizes the superconducting Tc. The promise of engineered high temperature superconducting materials, which could revolutionize computing, energy, and transportation industries, drives ongoing fundamental research into the interplay between SC and CDW order.
Asking Good Questions - Outreach workshop leads to Critical Thinking
Florianna Blanton, outreach coordinator at CHESS, presented to a group of Cornell Graduate students on Wednesday, March 10. The virtual discussion highlighted the unique ways in which graduate students can perform outreach with teachers and k-12 students in the area.
CHESS user examines material under thermo-mechanical loading - with goal to develop predictive material modeling
Residual stress can have a tremendous effect on the performance and overall lifetime of materials. To understand the lattice strains that result in these stresses, researchers at CHESS are able to probe their samples with high-energy X-rays while simultaneously exposing them to heat, strain, and pressure.
Grain-resolved temperature-dependent anisotropy in hexagonal Ti-7Al revealed by synchrotron X-ray diffraction
Synchrotron measurements of a titanium alloy reveal anisotropic coefficients of thermal expansion that would not be able to be seen with bulk measurements.
Q&A with Ryan Hurley, NSF Early CAREER Award Recipient
"The award allows me to plan long-term, to take risks in experiment design and execution, and to carefully integrate my teaching and outreach with my research." Ryan Hurley, Assistant Professor at Johns Hopkins Whiting School of Engineering and Fellow of the Hopkins Extreme Materials Institute, is a recipient of the NSF Early CAREER Award, which recognizes early-stage faculty who integrate education with their promising research.
Fe Cations Control the Plasmon Evolution in CuFeS2 Nanocrystals
Research on the synthesis of CuFeS2, an exciting semiconductor, outlines a method to verify its phase purity and investigate its properties.
Approaching the ideal limit for spin-orbit-coupled quantum moments in iridium halides
New research from a large team from 5 Universities and 2 National Labs reports on a new family of iridium halide materials that provide the best-yet realization of the ideal quantum limit for spin-orbit coupled magnetic moments. These Jeff=½ magnets are promising systems to engineer new kinds of superconductors and realize new kinds of magnetic interactions.
