Improving the Electrical Percolating Network of Carbonaceous Slurries by Superconcentrated Electrolytes: An Electrochemical Impedance Spectroscopy Study.

Semisolid redox flow batteries simultaneously address the need for high energy density and design flexibility. The electrical percolating network and electrochemical stability of the flowable electrodes are key features that are required to fully exploit the chemistry of the semisolid slurries. Superconcentrated electrolytes are getting much attention for their wide electrochemical stability window that can be exploited to design high-voltage batteries.

COVID-19: ensuring our medical equipment can meet the challenge.

To predict the spread of coronavirus disease globally and consequently prepare the hospital facilities with the required technology is a challenge. The availability of essential medical equipment to support patients affected by Covid-19 is globally limited. Areas covered This perspective gives a technical view of the pandemic focusing on the main actions taken by regulatory agencies to cope with the shortage of devices.
