US Patent:

6483077, Nov 19, 2002

Filed:

Jan 9, 2001

Appl. No.:

09/757194

Inventors:

Charles E. Albright - Powell OH
Joseph W. Rich - Worthington OH
Richard B. Miles - Princeton NJ
Walter R. Lempert - Columbus OH
Sergy O. Macheret - Princeton NJ

Assignee:

The Ohio State University - Columbus OH

International Classification:

B23K 9067

US Classification:

2191304, 361117

Abstract:

A method and associated apparatus for initiating and guiding an electrical discharge arc. This method preferably comprises the steps of: providing a laser beam through a predetermined gas comprising molecules amenable to vibrational excitation by a laser beam so as to cause vibrational excitation of the molecules and to define a beam path in a direction of desired electrical discharge; and propagating an electrical discharge arc so as to intersect the beam path, whereby the electrical discharge arc is directed along the beam path.

Abstract:

The present invention includes carbon synthesis devices and systems. The invention also includes machines and instruments using those aspects of the invention. The present invention also includes methods of carbon synthesis. The present invention includes an array of carbon nanotubes, each nanotube having a longitudinal axis. The nanotubes are placed into an array such that the longitudinal axes of all nanotubes in the array are substantially parallel. The array may be a two-dimensional array or a three-dimensional array. The present invention also includes methods of preparing such carbon molecular clusters and arrays thereof.
