A novel imaging mode, neutron dark field imaging, extends the capability of neutron imaging to enable one to measure the microstructure, that is length scales from the nm to µm. The dark field is a measure of the pair correlation function, which is linked to conventional small angle. Neutron dark field images of lithium-ion batteries provide spatially resolved measurements (with resolution ~100 µm) of the particle distribution along the path of the neutron beam. We applied neutron dark-field imaging to commercial lithium-ion batteries with different capacities, states of charge, and wear. The images probed length scales from 100 nm to 3 µm. We observed a uniform dark field signal across the fresh battery in both charge states which is contrasted with the worn batteries, which show clear inhomogeneities in the dark field signal, which indicates that the underlying electrode structures have changed in a non-uniform fashion.

During a high‐speed road traffic accident, a 26‐year‐old man suffered multiple fractures of his thoracic vertebrae and bilateral pneumothoraces. The day after admission and commencement of nasogastric feeding, milky fluid was noted in his right chest drain. Feeding was stopped and a contrast oesophogram and oesophagoscopy were performed, which were normal. The chylothorax quickly resolved and both drains were removed on day 6. Initial treatment of chylothorax aims to decompress the pleural space and minimise chyle production by not feeding the patient via the enteral route. Most authors recommend conservative management for 2 weeks or more unless certain parameters are met: average daily chyle loss of > 1.5 l for a 5‐day period, or imminent nutritional complications. In this case, surgical management of the chylothorax and spinal fractures was planned. However, conservative management was successful, highlighting the fact that early aggressive surgical intervention for chyle leaks in blunt trauma is not necessary.
