William Osman (born June 8, 1991) is an American YouTuber and engineer based in Ventura, California.He makes videos about science and robots. He has gone viral for a 2017 video featuring a laser cut sculpture of Vin Diesel made of a ham and cheese sandwich and a 2021 video featuring a homemade X-ray machine.
Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and ...
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Potentially, liquid-crystal lasers could form the basis for "lab on a chip" devices that provide immediate readings without sending a sample away to a separate lab. [ 28 ] Medical: low emission power limits such medical procedures as cutting during surgeries , but liquid-crystal lasers show potential to be used in microscopy techniques and in ...
Chemical reaction in a burning jet of ethylene and nitrogen trifluoride (NF 3) Used in research for laser weaponry, operated in continuous-wave mode, can have power in the megawatt range. Deuterium fluoride laser ~3800 nm (3.6 to 4.2 μm) (~90% atm. transmittance) chemical reaction US military laser prototypes. COIL (chemical oxygen–iodine laser)
A TEA laser is a gas laser energized by a high-voltage electrical discharge in a gas mixture generally at or above atmospheric pressure. The most common types are carbon dioxide lasers and excimer lasers , both used extensively in industry and research; less common are nitrogen lasers .
An important factor is that the bubble contains mainly inert noble gas such as argon or xenon (air contains about 1% argon, and the amount dissolved in water is too great; for sonoluminescence to occur, the concentration must be reduced to 20–40% of its equilibrium value) and varying amounts of water vapor.
In the media this was dubbed "burning salt water". Both effects involve the use of his radio frequency transmitter . Kanzius, self-taught, stated that he was motivated to research the subject of cancer treatment by his own experiences undergoing chemotherapy for treatment of non-Hodgkin's lymphoma .
