What is Micelle? Micelles are colloidal aggregates formed by the self-assembly of amphiphilic molecules (surfactants) in a solvent above a critical concentration, known as the critical micelle concentration (CMC). They consist of a hydrophobic core and a hydrophilic outer shell, with the hydrophobic tails oriented inwards and the hydrophilic heads outwards in polar solvents like water, or vice versa in non-polar solvents (inverse micelles) Properties of Micelle Formation Mechanism of Micelle Before reaching the CMC, surfactant molecules arrange themselves at the solvent-air interface. Above the CMC, they spontaneously self-assemble into micelles, driven by the hydrophobic effect and minimization of free…
What is A Turbine Engine? A turbine engine, especially a gas turbine, spins powerfully by harnessing energy from combusted gases flowing through it. This ingenious design transforms the kinetic energy of gases into mechanical work, directing them onto rotor blades. As the gas strikes the blades, it generates an impulse, spinning the rotor at incredible speeds. How Does A Turbine Engine Work? A gas turbine engine typically comprises the following main components in serial flow arrangement: The rotor section, which passes through the center of these sections, is connected to a drive shaft (e.g., for a generator or propeller). The…
