What is plasma sputtering?? Hi, I've got a undergrad exam coming up and i can't describe the process of plasma sputtering :cry: , can't find much on the web .. any help would be greatly appreciated

When I was doing science fair projects in astrophysics, sometimes I felt like asking my mentor random astronomy questions that I had in my mind. He was a very great man and taught me a lot about astronomy and kept my interest in the subject alive such that I decided I wanted to major in...

if you have a device similar to a stun gun, with a spark continuously jumping across the 2 contact points. electric field has to rip electrons from the air moecules leaving positive ions - creating plasma. now imagine you have a negatively charged disc nearby the device which is covered in a...

Hey! I don't Know if I put my post in the right forum but How can i using LRC circuit in plasma?? Could anyone help me Thakns

I thought plasma was the most energetic state of matter, and that heat is proportional to energy levels? How is it possible for cold plasma then?

I have read Fundamentals of Physics by Resnick and Halliday. My goal currently is to delve into quantum and plasma physics. Can you suggest any good, comprehensive books. My Math knowledge is pretty basic (just done some integral calculus 12th grade level) Can you suggest books for maths to...

Hi, This is my first post on this forum. My question is How is motion of plasma controlled through magnetic fields since it is electrically neutral. My understanding is that since plasma conducts current, a current is passed through plasma and then a magnetic field is applied which...

I found this. Is it cranks or for real? http://www.progressiveengineer.com/PEWebBackissues2002/PEWeb%2028%20Jul%2002-2/28editor.htm http://www.focusfusion.org/

Can someone please explain to me how a plasma ball works? I think I kind of get it. I get that the current flows through the gas inside of the ball because there is a large enough electrical potential difference between the two points. I'm not sure why the sparks follow you finger around the...

Dear Folks: I have posted this Question all over the web, physics forums, science magazines, academics in plasma physics and condensed matter, I have received little response. Can you be of assistance? I thought this might interest you. I have been researching Hydrogen-boron...

people as mass increases its acceleration it increases in energy, therefore decreases in mass. and this true because high energy plasma has no particles.

what is the Baisc of laser plasma?? i just found about Laser-Plasma Interactions , but i would Know what is the theory of laser plasma and who was the first person studied this subjet?? could anyone help me!

Could someone please explain the difference between a gas that has entered its plasma state and an ionized gas?

Dear Sirs: I have posted this Question all over the web, physics forums, science magazines, academics in plasma physics and condensed matter, I have received little response. Can you be of assistance? I thought this might interest you. I have been researching Hydrogen-boron Fusion...

Hi, When air is heated to a point where it turns into a plasma, is there any equation which governs how much the gas expands in the explosion? Thanks

How does a plasma ball work? http://www.iwantoneofthose.com/PLABAL_GADG.htm

Equation of state for quark-gluon plasma is p=(127/6) (stephan-boltzmann const/ speed of light) T^4 internal energy is U=3pV = (127/2)(stephan-boltzmann const/ speed of light)(T^4)V So how does one get an expression for entropy? or if anyone knows the expression what is it? (I may be...

Most of us know that when a liquid goes to a gas its called evaporation. We also know of deposition, sublimation, condensation, etc., but what are the names of the changes dealing with plasma? If plasma were change into a liquid, it is called? A solid? A gas? Are these even possible...

Would a quark-gluon plasma reflect x rays and gamma rays and would such a plasma exist in gamma ray bursters and black holes?

What is Quark-Gluon Plasma? Is it mearly a concieved, observed, theorized, or even created in a lab? What are/could be its uses? Thanks!

Hi, I'm currently doing an research experiment into the behaviour of plasma around magnetic fields. I will be using an arc welding machine for the plasma and an electromagnet. (So I can adjust the field's intensity as an independant variable.) The arc should bend in the presence of a magnetic...

I was reading about plasma the other day, and I was really impressed how it interacts with magnetic field. Reasons as to why it behaves the way it does were clearly explained, but I ran into a couple of problems: If there is a magnetic field inside plasma, compressing plasma also compresses...

just want to ask, what is their difference? which is better? to me, a Sony DRC Wega or Panasonic Tau flat screen TV (CRT tube) is very good enough for visual pleasure.

can anyone help me out with this question:In order to lift a wire ring of radius 2.07 cm from the surface of a container of blood plasma, a vertical force of 1.90×10-2 N greater than the weight of the ring is required. Calculate the surface tension of blood plasma from this information. I can't...

I know that when an atom reachs the plasma stage its electrons have gone through diffrent orbitals getting consecutivly larger. I have a question about what happens as an atom approches absolute zero. as the atom gets colder do its electrons move into smaller orbitals until they crash into...

if i used existing laser focusing tube, with lens and everything, and i drill two holes inside a tube, parallel to each other with conductors inside them so they make a spark gap, and discharge 320 kV inside it, would light that is emitted from air plasma be sufficient to make nice beam? few...

Plasma Curtains or Artifical Curtains or Light Curtains.. Can anyone think of a way we can creat a light barrier that can be switched on and off to restric view ? So you want to partition a room into two...you put up this light barrier in the middle of the room which can be walked through...

Greetings. According to my textbook (again, this might not be really accurate because of translation): Now, here is my question : If proteins are just molecules (big ones i guess), how do they 'know' what the cell needs at a certain time (to let it into the cell) ? Thanks in advance.

This guy is effectively asking for donations on EBay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2193742726&category=14431 This is the patent...

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2193742726&category=14431 I was going to post this in engineering, but I think this is more suitable. Can someone take a look at this page real quick? It sounds pretty cool, like something from star trek, so I'm pretty sure it needs to be...

Keep in mind I have not studied fluid dynamics or plasma stuff at all... Now, both gases and liquids are fluids. Is a plasma an ionised gas, or an ionised fluid? The reason I ask is because the big difference between the gas and liquid forms of various things is the amount of energy. Is...
