Taylor cone electrospinning. You have to know what spin is: The spin of an elementary particle is one of the properties that describe the particle. Just like mass or charge. There is no movement reaction. But it is interesting to know that if the particle is charged, its spin plays a role in this phenomenon as it interacts with the magnetic field and behaves as if a charged particle were “spinning”. But that wouldn’t be true spin, because if the electron showed the behavior we know as spin, it would have to be able to spin a little slower or a little faster than normal. But in reality it is not so. There are only 2 “Spin” modes. In this context it can be said that the spin is actually the most important property of the particle; Because it determines how it stays together with other particles.

When the spin is “half” we call the particle a fermion and when it’s “full” we call it a boson. Fermions cannot coexist, bosons want to coexist. Thomas in 1926; Kroenig realized that the double error in Uhlenbeck’s and Goudsmit’s calculations was due to special relativity. In 1928, Dirac began to wonder why we should think about the spin of electrons, and he decided to reconstruct his theory of relativity for electrons. With this he succeeded in wonderfully generalizing the Schrödinger-Pauli equation. In this way he managed to automatically remove the concept of spin from the equations.

Not only that: he didn’t set up an equation just for electrons. He also developed an equation for positively charged particles with the same mass as electrons. These particles, called positrons, were first discovered in 1931.Later studies showed that the Dirac equation is not valid at high energy levels. It took another 25 years to develop a theory of electrons and photons that covered all energy levels. Many have contributed to this theory. However, Feynman, Schwinger and Tomonaga, the fathers of the theory we know as quantum electrodynamics, received the Nobel Prize for developing this important theory.

So the dance between theoretical physics and experimental physics has passed many Nobel prizes and gives us an explanation for the spin behavior of electrons.

In recent years, it has been used to make nanofibers. The functional principle and the resulting test setup are extremely simple: generate an electrically charged field with high voltage and spread the polymer out in the form of fibers and collect it in the collector. The origin of the company dates back to 1934. One of the methods of making fibers (fibers) is that forming neck allows to make polymer filaments by applying an electrostatic force (there are several patents for this method). Therefore; There is a need for a syringe containing molten polymer, a manifold, a power source, and a syringe pump that causes the polymer to enter the electric field at the tip of the syringe with some pressure.

Although comparing the vibration of the polymer in an electric field to the vibration of a garden hose provides a good analogy, the use of a wrist strap is useful when working near the complex.

This technique converts a drop of polymer at the tip of a needle into a fiber by exposing it to electricity. It’s a simple method, the optimization is tedious, but done quickly thanks to a sophisticated optimization table. Electron microscopy is absolutely necessary to characterize the fibers so you can see what they look like in the real world. There are a multitude of variations, from the suitability of the solvent used to the molecular weight of the polymer, from the voltage applied to the flow rate of the syringe pump.

Its brother, on the other hand, which processes polymer fibers with compressed air, is also known as blow spinning.
