Nanofibers are fibers with diameters in the nanometer range. The development of nanofibers has greatly enhanced the scope for meeting up the modern world challenges. Currently there are two types of electrospinning systems available for producing nanofiber: needle based electrospinning and needleless electrospinning. This paper summarizes the basic mechanism of various typesLive Chat
Types Positive displacement pumps A lobe pump A positive displacement pump causes a fluid to move by trapping a fixed amount of it then forcing (displacing) thatLive Chat
Apart from these basic uses, the different types of couplings devices have different uses which are mainly reflected in the material, flexibility, and utility. To give a broad overview, a good and efficient coupling device is an absolute necessity for the machine or system to function optimally. Types of CouplingsLive Chat
