SEDONA and ERDE: Portable Detection of Chemical Agents by Low Magnetic Field Nuclear Magnetic Resonance [Slides]
Two spectrometer systems have been developed at LANL for hazardous and/or toxic chemical agent detection and forensic analysis: SpEctroscopic Detection Of Nerve Agents (SEDONA) is a portable bottle scanner; and Earth’s field Resonance Detection and Evaluation (ERDE) Devices are fieldable J-coupled Earth’s Field - NMR (EF-NMR) spectrometers.
Understanding aging mechanisms in Li batteries through in-situ and ex-situ nuclear magnetic resonance
This report discuss aging mechanisms and cycling performance of Li batteries, and considers the influence of both the passive and active materials. To achieve this aim we developed in situ coin cell and pouch cell NMR probes as well as HR-MAS NMR protocols to study cells with as a little modification as possible.
Muon capture and nuclear giant resonances
Interrelation of giant resonance excitations by muon capture with other electromagnetic and weak excitations
Nondestructive testing of adhesive bonds by nuclear quadrupole resonance method
Inert, strain sensitive tracer, cuprous oxide, added to polymeric adhesive ensures sufficiently large signal to noise ratio in NQR system output. Method is successful, provided that RF-transparent structural materials are used between modified adhesive and probe of NQR spectrometer.

Study of the extra-ionic electron distributions in semi-metallic structures by nuclear quadrupole resonance techniques
A straightforward self-consistent method was developed to estimate solid state electrostatic potentials, fields and field gradients in ionic solids. The method is a direct practical application of basic electrostatics to solid state and also helps in the understanding of the principles of crystal structure. The necessary mathematical equations, derived from first principles, were presented and the systematic computational procedure developed to arrive at the solid state electrostatic field gradients values was given.
