The Survey of Radiation Dose in Radiofrequency Catheter Ablation

Japanese Journal of Radiological Technology, 2013
Interventional radiology (IVR) is a technique using image guidance such as X-ray fluoroscopy to perform diagnostic and therapeutic procedures. It is widespread, and its use continues to increase. Radiofrequency catheter ablation (RFCA) has a long fluoroscopy time, and ablation procedures may be repeated in a single session.

Plasma Treatment on 1D Tungsten Disulfide Carbon Core–Shell Composites for Improved Performance in the Hydrogen Evolution Reaction

Small, EarlyView.
RF Ar plasma exposure selectively activates carbon‐coated WS2 nanotubes, substantially lowering the HER overpotential while preserving an ordered, conductive framework. A subsequent D2 plasma step produces interlayer expansion and greater structural disorder, reducing activity.
