Electric, Thermoelectric and Magnetic Properties of Nickel(II) Imine Nanocomplexes
Production of novel organic semiconductor nanomaterials is essential for enabling the development of personal, portable and flexible electronic modules. This work presents Ni(II)-Schiff base complexes with enhanced Seebeck coefficient and weak ferromagnetic ordering for thermoelectric and magnetic devices. Four Ni(II)-Schiff base complexes (namely [Ni(C12">1212H10">1010N3O4Br)]⋅">⋅⋅2H2O, [Ni(C16">1616H11">1111N3O4)">4)4)]⋅">⋅⋅2H2O, [Ni(C21">2121H14">1414N5O8Br)] and [Ni(C25">2525H17">1717N5O8)">8)8)]⋅1/2">⋅1/2⋅1/2H2O) have been synthesized in nanosized dimensions. The electrical and thermoelectric properties have ... Read more

The synthesis of CuO and NiO nanoparticles by facile thermal decomposition of metal-Schiff base complexes and an examination of their electric, thermoelectric and magnetic Properties
In this study, CuO and NiO NPs have been synthesized by facile thermal decomposition of Schiff base complexes and their physical properties have been examined. The synthesized CuO and NiO NPs are crystallized in polycrystalline monoclinic and cubic structures with average particle size 17 ± 0.4 and 62 ± 1 nm, respectively. The electrical conductivity measurements confirm that the conduction ... Read more

On continuous dependence for the mixed problem of microstretch bodies
We do a qualitative study on the mixed initial-boundary value problem in the elastodynamic theory of microstretch bodies. After we trans-form this problem in a temporally evolutionary equation on a Hilbert space, we will use some results from the theory of semigroups of linear operators in order to prove the continuous dependence of the solutions upon initial data and supply ...
