Determination of epinephrine in human serum using a Pt electrode modified by polyaniline-poly(3-methylthiophene)-poly(3,3 '-diaminobenzidine)
(Canadian Science Publishing, Nrc Research Press, 2015)
A Pt electrode modified by polyaniline-poly(3-methylthiophene)-poly(3,3'-diaminobenzidine) was used for amperometric determination of epinephrine in a solution of NaHSO4/Na2SO4 (pH 2.0). For these studies, potentials between ...
Molecular aggregates of Merocyanine 540 in aqueous suspensions containing natural and CTAB-modified bentonite
(Elsevier Science Bv, 2015)
The molecular interactions of MC-540 (Merocyanine 540) in clay suspensions containing natural bentonite and CTAB (cetyl trimethyl ammonium bromide)-modified bentonite were examined by using absorption, steady-state and ...
Microwave-assisted synthesis of some new coumarin derivatives including 1,2,4-triazol-3-one and investigation of their biological activities
(Springer, 2015)
By using the microwave technology, a new protocol has been developed for the synthesis of new coumarin derivatives including 1,2,4-triazol-3-one skeleton. This protocol proves to be efficient and environmentally friendly ...
