Which of the following is a component of a syringe.The electrode creates a single, stable polymer beam from the tip of the Taylor cone by focusing electric field lines that extend along the needle tip to the needle tip. The fiber bundles emerging from the formed stable electrospinning jet flow toward the center of the EtOH bath, and stable structures are formed together.
The booster electrode also makes it possible to increase the polymer flow rate without having to climb to very high voltage levels. This increased the flow rate from 1 ml/s to 2 ml/s and kept the voltage constant at 15 kV. Conical electrode with 1.5 mm needle tip is placed in front of it. As a result of the series test, the distance between the tip of the needle and the surface of EtOH was found to be 12 cm. In addition, the electrical contacts of the motor assembly are concealed within the wooden housing of the motor so as not to interfere with the electric field generated by the high voltage source.

During the electrospinning process, a boosting electrode used in previous studies was added to the needle tip. For each pattern, initial experiments were performed with different electric field rotation speeds, and as the electric field rotation speed increased, it was observed that the three-dimensional structures were connected concentrically toward the center of the coagulation bath. With the sudden drop in air temperature in December, the surface tension of EtOH increased and it became impossible to collect the sample under ambient conditions. First in the electrospinning cabinet.

Which of the following is a component of a syringe?

It was heated, but when this heat was not enough to raise the temperature of the EtOH, EtOH being rapidly heated and cooled, the EtOH added to the coagulation bath was heated to a temperature of 40°C. Table 3.2 gives the bath temperature and operating parameters of the structures associated with different electric field rotation speeds.

When the assembly is removed, this reassembly takes place within the electrode and reactor. The distance has not changed. The position of the needle tip is close to the reactor opening, but not too far away.
It is chosen so that it is not attached to the reactor at the end of the accumulation for sample transfer Its removal from its current location is simplified.

Which of the following is a form of IV injection

Upon bringing the fibers together in a coagulation bath filled with EtOH, the binding behavior of the fiber bundle falling from the surface of the beverage to the bottom of the Petri dish is converted into EtOH formed by branching out of the fiber stream. and contains hundreds of fibers is affected by the surface tension of EtOH, which varies with ambient temperature. ambient temperature
Upon cooling to room temperature, the fiber bundle accumulates on the surface before it can penetrate EtOH since surface tension increases inversely with temperature.

As a result, the distance between the tip of the needle and the Teflon tape is 6 cm, millet electrode and EtOH. The total distance between the needle tip and the EtOH is 5 mm.
The distance is defined as 8 cm. the results of preliminary tests; Flow rate 2ml/h, original The voltage is defined as 15 kV, the electrode voltage on millet as 3 kV.

What materials are used in electrospinning?

Figure 3.9 shows the surface tension variation of EtOH between 4 and 35 °C. Fiber bundles that can overcome the surface tension drop of heated EtOH are assembled in a glass Petri bath with different patterned electric field orientations. However, since heated EtOH cooled at about 1°C/min, it was unlikely to maintain its temperature.

For this reason a controlled temperature coagulation bath was constructed and further experiments with this bath continued.
The obtained structures were cleaned by electric field rotation of EtOH and dried at room temperature and a freeze dryer at -80°C. 3D structure and freeze dried structures lost their 3D structure.
The structure was observed.

Nation 1 cm wide The electrode inside the reactor is supported by a Teflon tape 1.5 cm thick. is placed more than 1 cm on the EtOH surface electrode.
When the gap disappears, the glass bonds to the inner wall of the reactor and to the metal on the electrode. It is realised. For this reason, the electrode should be placed 5 mm above the EtOH level.
is placed When the voltage from the stress mill to the electrode is 3 kV, the polymer will squirt It’s stable. When this voltage increases to 6 kV, the voltage becomes 9 kV.
If it is kV, the assembly is first on the electrode, then on the glass wall of the reactor, and the reactor tells the nation. Outside, he noticed that the distance between the tip of the needle and the millet electrode was more than 6 cm.
