Porous Carbon Electrodes

open access: yesTransactions of The Electrochemical Society, 1939
Various applications of porous electrodes are described and their usefulness in electro‐oxidations and reductions, both organic and inorganic, is discussed. Three processes are considered in detail : electrowinning of copper, production of p‐nitraniline, and oxidation of arsenite to arsenate with accessory air depolarization at the cathode.

Electrostatic‐Assisted Liquefaction of Porous Carbons

open access: yesAngewandte Chemie International Edition, 2017
AbstractPorous liquids are a newly developed porous material that combine unique fluidity with permanent porosity, which exhibit promising functionalities for a variety of applications. However, the apparent incompatibility between fluidity and permanent porosity makes the stabilization of porous nanoparticle with still empty pores in the dense liquid ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.
