Tungsten Carbide Nanoparticles Embedded in Carbon Nanofoam Composites for Efficient Electrocatalytic Hydrogen Evolution

Advanced Energy and Sustainability Research, EarlyView.
A tungsten carbide nanoparticles/carbon nanofoam composite is presented as an efficient electrocatalysts towards hydrogen evolution reaction. The simultaneous ablation of tungsten and carbide via pulsed laser deposition results in homogeneous and dense dispersion of tungsten carbide particles in the carbon matrix.

Two‐Stage Treatment for Adult Large Patent Ductus Venosus

Annals of Gastroenterological Surgery, EarlyView.
This is the first report of a two‐stage treatment for an adult large PDV involving the first stage surgical angioplasty of the large Arantius' duct and second stage embolization of the formed small Arantius' duct. The two‐stage approach could avoid embolic material migration into the systemic circulation or acute portal hypertension associated with the
