+                    The Electrospinning process is based on the electrohydrodynamics phenomenon, where a material substrate loaded within a syringe
+                    with a charged needle tip attached pointing towards a grounded collector is extruded and subsequenlly stretched using a high volatage potential.
+                    Assuming that the material substrate is viscoelastic enoough and as soon as the electrostatic stresses overcome the surface tension
+                    of the material, fibers in a chaotic motion are deposited on teh collector. The fiber formation mechanism is shown in the video below:

+                    The two main types of electrospinning process are: a) solution electrospinning and b) melt electropsinning.
+                    This classification is based on the material form used for processing with SES using polymer solution (pellets/powder
+                    mixed with solvent) and MES using pure polymer melt without any chemical solvents. THe 3 main common components 
+                    for both processes are: a) extrusion device that can be either mechanical using a syringe pump or pneumatic, 
+                    b) a high-voltage power supply and c) a collector that in the most basic setup is a flat grounded aluminum plate.
