/*File MusicComposer09.java Copyright 2014, R.G.BaldwinRevised 08/27/14 This is a driver class for playing piano melodies. It works inconjunction with the following classes: AudioSignalGenerator02AudioPlayOrFile01 AudioFormatParameters01PlayerPiano01 The melody to be played is defined in one and optionally two text files. Therequired text file defines the notes and the duration of those notes on the treble clef. The optional text file defines the notes and the durations ofthose notes on the bass clef. Those text files must exist in a subfolder named Music.The melody can be played immediately or can be saved in an audio file of type AU for playback later.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
