This study was designed to experimentally measure the thermal and electrical conductivities of Aluminium Nitride/Ethylene Glycol (AlN/EG) nanofluids. Transmission electron microscopy (TEM) was used to characterize the shape of AlN nanoparticles. Nanofluids with different particle volume concentrations of 0.5%, 1%, 2%, 3%, 4%, and 5% were utilized. The thermal and electrical conductivities of the...

Background: The aim of the study was to compare the effects of two different concentrations of cryoprotectants by Cryotop vitrification on survival and Heat shock protein 72 (Hspa1a) expression of two-cell mouse embryos. Materials and Methods: Different cryoprotectants’ concentrations of the combination of dimethyl sulfoxide (DMSO) and ethylene glycol (EG) were used and compared with each other...

A model of localized classical electrons coupled to lattice degrees of freedom and, via the Coulomb interaction, to each other, has been studied to gain insight into the charge and orbital ordering observed in lightly doped manganese perovskites. Expressions are obtained for the minimum energy and ionic displacements caused by given hole and electron orbital configurations. The expressions are ...

Let M be a compact connected Fujiki manifold, G semisimple affine algebraic group over C with one simple factor and P fixed proper parabolic subgroup of G. For holomorphic principal G–bundle EG M, let EP the P–bundle EG⟶EG/P given by quotient map. We prove that following three statements are equivalent: (1) ad(EG) is numerically flat, (2) line bundle ⋀topad(EP)⁎ nef, (3) for every reduced irred...

The building sector is targeting net-zero emissions through the integration of renewable energy technologies, especially for space cooling and heating applications. In this regard, use solar thermal concentrating collectors vital importance. performance these increases by using an efficient fluid such as a nanofluid due to their high conductivity. This research addresses preparation, stability ...
