We use freestanding sheets of MWCNTs, either purified and subsequently not modified with impurities (pure) or purified and subsequently contaminated with carbonaceous impurities (impure), as electrodes to eliminate the need for a substrate and thus undesired mixed kinetics.
The magnitude of electrical conductivity was close to 10−4 to 10−5 S cm−1, i.e. least more than one order of magnitude larger than that of TMOS based silicate matrix modified with a pure solvent.
These additives consist of pure aluminum bromide (AlBr3) and/or fumed aluminum oxide (Al2O3) filler, pure and modified with H2SO4.
Ten modified with the modifier content 1%, 3%, 5% and pure bitumens were tested and characterized in accordance with the Superpave performance grading (PG) system.
In this work, we investigate hexagonal mesoporous silicas (HMS), pure or modified with metal cations having redox properties (Ce, Fe), as supports of gold NP catalysts for the aerobic oxidation of 1-octanol under green process conditions.
Because of the different diameters of CNTs, this current intensity was proportional to the scan rate for the electrodes modified with the LB films of pure H2ase and SWNTs H2ase, but to the root of scan rate (υ1/2) for those modified with the MWNTs H2ase LB film.
Ultrapolished surfaces of commercially pure titanium were modified with 16-phosphonohexadecanoic acid and octadecylphosphonic acid.
The electrode surface was modified with different amounts of redox liquids (pure t-butylferrocene, solutions of t-butylferrocene in 2-nitrophenyloctylether, and N,N,N′,N′-tetraoctyl-1,4-phenylenediamine) using hexane solutions and a solvent evaporation approach.
Accordingly, pure alumina was systematically modified with varied amounts (0.5 10 wt.%) of K+ or SO42 − additives.
