unsteady hydromagnetic generalised couette flow of a viscous, incompressible and electrically conducting fluid between two horizontal parallel porous plates darcian channel in the presence of a uniform transverse magnetic field taking hall current and ion-slip into account in a rotating system is investigated. an exact solution of the governing equations is obtained by laplace transform techniq...

The equation for the size strain plot methods reported by A. Khorsand Zak et al. (Solid State Sci. 13 (2011), 251) [1] does not follow dimensional homogeneity, consequently leading to an inaccurate estimation of crystallite and values materials under investigation dimensions obtained parameters. We also perceived error in authors using size-strain method. will discuss importance analysis its re...

The discovery of the planar Hall effect in topological semimetals has generated extensive research interest recently. We present studies on Cu intercalated type-II Dirac semimetal PdTe2 order to understand role chiral anomaly. observed a positive field dependence electrical resistivity both perpendicular and parallel directions, causing non-zero anisotropy. signal anisotropic oscillate with in-...

There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...

In this report, ZnO nanoparticles (NPs) was synthesized by chemical method using Zinc Acetate dehydrate [Zn(CH3COO)2.2H2O)] as precursors and Ethanol distilled water solvent. Sodium hydroxide (NaOH) used to maintain the pH helps establish NPs. The NPs are characterized XRD, UV-visible spectroscopy SEM image analysis. XRD characterization gives polycrystalline nature of with size ~23 nm ~27 calc...
