The substrates were treated with a mixture of concentrated sulfuric acid and concentrated nitric acid before usage to functionalize with carboxylic and hydroxyl groups.
In the first stage, three types of acids are utilized, namely, concentrated HNO3, concentrated HF, and a mixture of concentrated HNO3 and HF.
The terrorists used the flat to make the bombs from an "entirely unique" mixture of concentrated hydrogen peroxide and pepper, the hearing was told.
It was first prepared in 1846 by the Italian chemist Ascanio Sobrero by adding glycerol to a mixture of concentrated nitric and sulfuric acids.
The bombs used in the attacks on three tube trains and a double-decker bus contained about 10kg of explosives made from a mixture of concentrated hydrogen peroxide and pepper and detonated by a 9-volt battery.
MWCNTs were first treated by a 3 1 (v/v) mixture of concentrated H2SO4/HNO3, and then triethylenetetramine (TETA) grafting was carried out.
In this work, graphene oxide was synthesized by treating graphite powder with KMnO4 and a mixture of concentrated H2SO4/H3PO4 and reduced with ascorbic acid to produce reduced graphene oxide.
Chemically functionalised single-walled carbon nanotubes were formed using sonication in a mixture of concentrated sulphuric and nitric acids for varying lengths of time which resulted in carboxylic acid group functionalisation, predominantly at the ends.
Results indicate that a complete digestion can only be achieved if the two-stage digestion process is operated at a terminal temperature of 210 °C, coupled with a mixture of concentrated HNO3 and HF.
The mixture of concentrated emulsions was subjected to heating for the complete polymerization of the monomer and for the reaction between the epoxy resin and the amine terminated oligomer or the maleic anhydride to occur.
The oxidation of carbon nanofibers (CNFs) with various oxidizing agents; 6 M HNO3, KMnO4, RuO4, and a mixture of concentrated H2SO4/HNO3 is studied to determine the reaction conditions that optimizes yield and chemical functionalization.
