Spin off definicion. The humidity of the environment in which the polymer jet is located, the type of atmosphere and the pressure are factors affecting the fiber structure.

Spin off definicion

High ambient humidity affects the morphology of electrospun fibers, especially solutions made with a volatile solvent. In the literature studies examining the relationship between the relative humidity of the environment and the diameter of the fibers formed, it was observed that the diameter of the fibers obtained increases with increasing humidity.

That is, increasing the relative humidity decreases the intensity of the electric field required to thin the beam.

In 1845, Michael Faraday discovered that light is affected by the magnetic field when it passes through a material embedded in a magnetic field. What Faraday achieved in particular was the discovery of a plane where light “oscillates” in an electromagnetic field. Then he noticed that light “rotates” in this room. This was the first observation of the relationship between light and electromagnetism.

In 1862 Faraday attempted to show whether a magnetic field had a direct effect on light. Despite his best efforts, he found, as he put it, “no demonstrable effect.” But soon he is wrong. In 1870 James Clark Maxwell wrote about light sources and particles:

Maxwell was wrong too. In 1896 Zeeman decided to repeat Faraday’s experiments using better technology than in Faraday’s time. He lit table salt (which is important to us, the sodium atoms in table salt) and placed the mixture on an electromagnet. He discovered that when he activated the magnetic field, the number of specific frequencies in the light spectrum of sodium atoms increased. He proved for the first time that a magnetic field can influence the light spectrum. Maxwell was wrong too. In 1896 Zeeman decided to repeat Faraday’s experiments using better technology than in Faraday’s time. He set table salt (which is important to us, the sodium atoms in table salt) on fire and placed this mixture on an electromagnet. He discovered that when he activated the magnetic field, the number of specific frequencies in the light spectrum of sodium atoms increased. He proved for the first time that a magnetic field can influence the light spectrum. Today we know exactly how; At that time, however, electrons had not yet been discovered, so the explanation of how this event came about had to wait 30 years. In 1897 electrons, one of the fundamental particles, were discovered. Protons were discovered in 1919 and neutrons in 1932.

Spectral line multiplexing is important because such multiplexing requires interaction. Within the framework of electromagnetic theory, we know how a moving charge interacts with a magnetic field as it traverses it. On the other hand, Lorentz theory tells us how many lines we should see due to the interaction of light passing through the electromagnetic field with the field. The formation of these lines proves the interaction of light and electromagnetic field. But there was a problem: the number of lines observed was actually always twice what theory “should” say. Here’s the biggest inexplicable problem: the electron must have an additional property in addition to charge, and whatever that property is must be the cause of the double line.

It was such a daunting problem that in 1925 Pauli wrote about the multiplexing of the spectral lines of atoms in a magnetic field that was “undefinable by classical methods”. From that moment on, electrons are seen from a different angle. The answer comes from quantum mechanics. Kroenig, then a graduate student, suggested that the main reason for this property must be the spin of the electrons, a property called spin. He also discovered that the rotation must be half-integers with reduced units of Planck’s constant. Unfortunately, as we explained above, experimental data always scatter twice as much as theory predicted. Kroenig considered this a big mistake and therefore did not want to publish the results of the research.
