  1. An electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles. (APP 2002)
  2. YT what kind of voltage do you have in mind, 10,000 or 20,000, id go with the latter (j/k)
  3. Bose-Einstein condensates form from matter that has been cooled to near absolute zero. (APP 2002)
  4. Do you mean time travelling will have a conection to the speed of light?
  5. I think what is was meaning is the so called anti-ageing products that contain Alpha Hydroxy Acids ect....
  6. Sorry I didnt know you wanted in in "thermodynamics" so you should know that the chemical bonds are broken heat is released so the reaction is exothermic, and in the case of Ammonium Nitrate, endothermic, as when you dissolve the Ammonium Nitrate in water energy (heat) is requires about 26KJ/mol, sodium acetate(aq) ==> sodium acetate(s); So becoming: a/_\ ====> B~C/_\ So the two weak pi-bonds are converted into two stronger sigma bonds and the large negative entropy shows the change from pi to sigma.
  7. Leroy, i think i answered that question, if you have anymore just ask.
  8. Oh and bt redliner, i think you will be needing this: x=r*t*d =s~ l=t
  9. "Time= speed of light, i can prove it" I like to see this I do know that if a person is accelerated toward the speed of light time slows down for that person.
  10. I would actually think as you were spraying the LN out, it would evaporate before it even reached the plant/weed.
  11. you can pour LN on your hand, its just boils off, but never submerge your hand in LD it will fall off.
  12. Mr expert (lol), If you look at the Periodic Table, you can see the affect of these types of radiation, i.e. Alpha emission basicly takes 4 of the mass number and two of the atomic number, i.e. emitting a He atom, and Beta emission emites a e-.
  13. S`up Yo? don`t ya know how to do that? so right away it "gibberish" all of a sudden? *sheesh* get a grip ya`ll! LMAO nice one YT

    Oh and i think the best ones are called Durapore membranes filters.

    Yer they are usually 0.2 and 0.1 micron rated sterilising grade filters that are affective, for small quantities not litre(s), they have been around for a while, and do sterilise (to BS grade).

    Electrophoresis investigates the interactions between molecules native and SDS-PAGE and DNA footprinting, which i would call structural. As for the filter in this process filtration is not worth the bother as for time and money, autoclaviing is the most effective in both cost and time.

    The electrophoresis electrodes are made of platinum wires

    Well i dont think i can get internal finger prints LOL yw

    Yep its a method of separating substances, especially proteins, and analyzing molecular structure using an eletric field, you hit thespot

    Yes autoclaving is a word lol, tris is a Electrode Buffer, Stacking Gel Buffer and RNA isolator for use in Bio, and you are right about NaOH.
  21. The reason that metals can be “easily cut without shattering” or hammered into different shapes, is all to do with plastic deformations, these are the areas of the metal(s) where the atomic shift is disrupted, this allows the atomic shift to distribute when the force is applied, the cutting or hammering raises the amount of deformations, and the movement of the atoms are centred.

    The way is to Autoclave (have not said it for fun), like i said to reach a suitable pH then use the glacial acetic acid by-route step, with the addition of Na2EDTA. If you follow my steps you should create what you are intending to, and filtration is out of the question.
  23. wolfson

    help needed!

    Add (d&nr)H2O to 1 litre, autoclave for sterilisation that should be the solution, but I could do with knowing whether you are using the glacial acetic acid by-route step, if so use Na2EDTA by 3-2 TAE.
  24. Lenwe Welcome to Science Forums BTW MrL_JaKiri there is no need to laugh
