Lightweight magnesium nanocomposites: electrical conductivity of liquid magnesium doped by CoPd nanoparticles.

Appl Nanosci 2019 26;9(5):1119-1125. Epub 2018 Apr 26.

2Department of Metal Physics, Ivan Franko National University of Lviv, Kyrylo i Mephodiy str. 8, Lviv, 79005 Ukraine.

The effect of monodisperse bimetallic CoPd NP admixtures on the electrical conductivity of liquid magnesium was studied. Temperature dependence of the electrical conductivity of liquid Mg(CoPd), Mg(CoPd), and Mg(CoPd) alloys was measured in a wide temperature range above the melting point by a four-point method. It was shown that the addition of even small amount of CoPd nanoparticles to liquid Mg has a significant effect on the electrical properties of the melts obtained. Read More

Appl Nanosci 2017 13;7(8):893-903. Epub 2017 Nov 13.

Animal Biochemistry Division, National Dairy Research Institute (NDRI), Karnal, Haryana 132001 India.

An electrochemical aptasensor for detection of trace amounts of aflatoxin M1 was developed. This required immobilization of aptamer on screen printed gold electrode comprising of working electrode, counter electrode and reference electrode and was achieved by sequentially layering dithiodipropionic acid, streptavidin and biotinylated-tetraethylene glycol-aptamer. Immobilization of aptamer was monitored by cyclic voltammetry. Read More
