The laser ablation method yields around 70 % and produces primarily single-walled carbon nanotubes with a controllable diameter determined by the reaction temperature.

In 2003, Wang and Andrews carefully studied the preparation of PbH 4 by laser ablation and additionally identified the infrared ( IR ) bands.
43.
Although initially the tumors were regressing, their reappearance a few months later necessitated a new course, this time including laser ablation therapy and chemoembolization.

Transurethral electrovaporization of the prostate ( TVP ), laser TURP, visual laser ablation ( VLAP ), ethanol injection, and others are studied as alternatives.
45.
Therefore, in July 1985, he applied for a patent that described a method of modifying corneal refractive errors using laser ablation under a corneal flap.
46.
Another class of applications uses laser ablation to process the material removed into new forms either not possible or difficult to produce by other means.
47.
In processes without cleaning media like laser ablation and vibration cleaning, only the removed dirt has to be disposed of as there is no cleaning agent.
48.
Performing the laser ablation in the deeper corneal stroma provides for more rapid visual recovery and less pain than the earlier technique, photorefractive keratectomy ( PRK ).
49.
Small quantities of gaseous zinc ( II ) hydride have also been produced by laser ablation of zinc under a hydrogen atmosphere and other high energy techniques.
50.
In these situations a specialized delivery for management of the airway compression can be planned called the EXIT procedure, or a fetal laser ablation procedure can be performed.
