ప్లాస్మాతో ప్రయోగాలు భవిష్యత్తుకు ఆవిష్కరణలు
Plasma Exhibition Held in PB Siddartha College Vijayawada : సమాజం ఎన్నోసమస్యలు, సవాళ్లు ఎదుర్కొంటోంది. వీటన్నింటికి సైన్స్తో పరిష్కారాలు చూపొచ్చు. ప్లాస్మాను సద్వినియోగం చేసుకోవడం కూడా ఇందులో ఒకటి. సౌందర్య సాధనాల నుంచి విద్యుత్ ఉత్పత్తి వరకు ఎన్నో అవసరాలు ప్లాస్మా తీర్చుతుంది. భవిష్యత్తులో ఆవిష్కరించే చాలా సాంకేతికతల్లో దీని పాత్ర విశేషంగా ఉండబోతుంది.

00:05There is a lot of difference between writing on the board in art school and showing it to the students practically.
00:11If you show it directly, it will hurt the mind.
00:14That is why, in the age of science and technology,
00:16experiments with plasma, which are very useful, were presented in this way.
00:20With the Institute of Plasma Research in Gujarat,
00:23Vijayawada PV Siddhartha Art School held this exhibition.
00:27Music
00:33With the desire to learn new things,
00:35these students took advantage of the encouragement given by the art school.
00:39They were curious about how plasma is made.
00:42Plasma is usually made at high voltage and pressure.
00:46You can clearly see the plasma production through this glow discharge instrument.
00:50Students are saying that they can see plasma vehicles in the future just like this in plasma TV.
00:56What is plasma?
00:58Plasma is a matter of states.
01:00Just like solid, liquid and gases,
01:02plasma is the fourth state.
01:05It is homogenous.
01:07For example, if we put our hand in a bowl of water,
01:10how does the liquid water distribute?
01:13Plasma also has such properties.
01:15The remaining properties are like gases.
01:17How does plasma form?
01:20Plasma forms at high voltage and high pressure.
01:24In the atmosphere, lightning and thunderstorms,
01:27plasma is formed.
01:29In the interior, it forms at low pressure and high voltage.
01:33When high voltage is given,
01:35the air between the two electrodes is broken.
01:39The pressure there is lowered.
01:42After the low pressure, plasma is formed.
01:45Plasma can be used for personal beauty.
01:48For example, if there are pimples on the face,
01:50it can be treated with plasma grooming.
01:52It can also be used for hair growth.
01:54Students say that it can also be used for hair growth.
01:56Whether there are pimples or sparks on the skin,
02:00we can use this device to remove them.
02:03When we switch on this device,
02:05plasma is generated from this tube.
02:08Plasma sparks interact with our skin.
02:11So, nowadays it is very useful.
02:13When designing clothes,
02:15we use different colors for half-life.
02:17Due to this, not only the fire,
02:19but also the water in the entire body evaporates.
02:21Students say that if plasma is used,
02:23it can be used in many ways.
02:26Chemicals are used to fade the color on the skin.
02:30In addition, plasma can be used at low pressure
02:33to give natural color to the skin.
02:37This is plasma torch for textile.
02:39When we switch on this torch,
02:42cold plasma is released from this torch.
02:45Cold plasma does not damage the fabric.
02:48So, we use cold plasma.
02:50When cold plasma is released,
02:52it does not contact the fabric,
02:54but interacts with the air.
02:56Oxygen and Nitrogen in the air react.
02:58Ions are formed.
03:00Oxygen and Nitrogen are formed.
03:02This color is faded.
03:04Why do we use this method?
03:06There are many chemical methods.
03:08In chemical methods,
03:10more water is consumed.
03:12So, there is a water wastage.
03:14Even in the recycling process,
03:16water is not used.
03:18We can reduce water and pollution.
03:22Another method to work with plasma
03:24is Telsa Coil and RF Plasma.
03:26If we take electricity with it,
03:28it lights up automatically.
03:30These lights up only because
03:32there is electricity in the plasma.
03:34Plasma tube lights used in the house
03:36are used for this purpose.
03:38In the future,
03:40there are attempts to expand plasma.
03:42This is Tesla Coil.
03:44It was invented by Nikola Tesla in 1891.
03:46This is a two-cylinder.
03:48Primary and secondary.
03:50Primary has 6 turns of copper.
03:52Secondary has 1000 turns of vapour.
03:54When low voltage is applied in the primary,
03:56high voltage is produced in the secondary.
03:58A spark is produced near the pointer tip.
04:00This is called Corona Discharge.
04:02Normally,
04:04these bulbs glow
04:06only when they are connected
04:08to the wires outside.
04:10These bulbs glow
04:12only when they are connected
04:14to the wires outside.
04:16When the spark is produced
04:18near the pointer tip,
04:20these bulbs glow
04:22due to the magnetic field
04:24produced in the spark.
04:26These bulbs glow
04:28due to the magnetic field
04:30produced near the pointer tip.
04:32In Japan,
04:34they are trying to
04:36install an ice rink.
04:38When cooled below 181 centigrade,
04:40it is converted to
04:42diamagnetic.
04:44When placed on an ice rink,
04:46it is divided into two parts.
04:48Ice rink trains can run on it.
04:50Students say that
04:52they can supply electricity
04:54to the house.
04:56This is a superconductor.
04:58This is a superconducting material.
05:00At room temperature,
05:02it does not have superconductivity.
05:04It is called critical temperature.
05:06When cooled below 181 centigrade,
05:08it produces superconductivity.
05:10When cooled below 181 centigrade,
05:12it produces superconductivity.
05:14It is diamagnetic.
05:16It opposes the magnetic field
05:18and flows on the magnet.
05:20It is diamagnetic.
05:22This is called the Messner effect.
05:24Maglev trains use this effect.
05:26Maglev trains use this effect.
05:28The train runs on the track
05:30without any contact.
