Tannic acid-assisted in-situ interfacial formation of Prussian blue-assembled adsorptive membranes for radioactive cesium removal.

There is a growing interest in advanced materials that can effectively treat wastewater contaminated with radioactive cesium (Cs), which is an extremely hazardous material. Here, we report a new class of Cs-adsorptive membranes compactly assembled with Cs-adsorptive Prussian blue (PB) particles. The PB particle assembly was formed via an in-situ interfacial reaction between two PB precursors in the presence of tannic acid (TA) as a binder on a porous support.

Incidental findings of the lumbar spine at MRI during herniated intervertebral disk disease evaluation.

Objective: The objective of our study was to evaluate the frequency and types of incidental findings of the lumbar spine during MR evaluation for herniated intervertebral disk disease.

Materials And Methods: A total of 1268 patients (male-to-female ratio, 421:847; age range, 1-97 years) with clinically suspected herniated intervertebral disk disease underwent MRI of the lumbar spine. Musculoskeletal radiologists evaluated the MR examinations for the presence of incidental findings.
