Characterization of Nanofluids Using Experimental and Analytical Methods for Different Concentrations
Abstract: A fluid containing nanometer-sized nanoparticles is called nanofluid. These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. Nanofluids are a new class of fluids engineered by dispersing nanometer-sized materials (nanoparticles, nanofibers, nanotubes, nanorods, nanosheet, or droplets) in base fluids. They are two-phase systems with one phase (solid phase) in another (liquid phase). For a two-phase system, there are some important issues we have to face. One of …

Schrödinger Cat's Experiment's Interpretation and Parallel Universe or Multiple Universes
Abstract: Quantum mechanics provides us most fundamental descriptions of our most early universe, but there is a long-standing debate amongst theoretical physicists about what all these mathematics really mean in real world? The present three-dimensional (3D) universe, we humans experience daily since our birth, is probably just one of an enormous numbers of essentially classical worlds, and all quantum phenomena arise from a universal force of repulsions that prevented many universes …
