Howard W. Jaffe
Howard William Jaffe (February 16, 1919 – May 13, 2002) was an American geologist and mineralogist. He is a pioneer in the study of the crystal chemistry of rock-forming minerals and of the link between the structural attributes and the physical and chemical properties of minerals. Jaffe studied at Brooklyn College in New York, obtained B.A. in 1942. After graduating from college, he worked for the U.S. Bureau of Mines between 1942 and 1957 in a varieties of positions to assist Allied forces in wars. He worked for Union Carbide Corporation on developing the growth technique of YAG crystals, which is later widely used for laser surgery.

Laser Surgery
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery, neurosurgery, ENT, dentistry, orthodontics, and oral and maxillofacial surgery) as well as veterinary surgical fields. The primary uses of lasers in soft tissue surgery are to cut, ablate, vaporize, and coagulate. There are several different laser wavelengths used in soft tissue surgery. Different laser wavelengths and device settings (such as pulse duration and power) produce different effects on the tissue. Some commonly used lasers types in soft tissue surgery include erbium, diode, and CO2. Erbium lasers are excellent cutters, but provide minimal hemostasis. Diode lasers (hot tip) provide excellent hemostasis, but are slow cutters. CO2 lasers are both efficient at cutting and coagulating. Laser surgery is commonly used on the eye. Techniques used include LASIK, which is used to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brooklyn College
Brooklyn College is a public university in Brooklyn in New York City, United States. It is part of the City University of New York system and enrolls nearly 14,000 students on a campus in the Midwood and Flatbush sections of Brooklyn as of fall 2023. New York City's first public coeducational liberal arts college, the college was formed in 1930 by the merger of the Brooklyn branches of Hunter College (centered in Manhattan), then a women's college, and of the City College of New York (also Manhattan), then a men's college. Once tuition-free, the city's 1975 fiscal crisis ended the free tuition policy. The college also consolidated to its main campus. Prominent alumni of Brooklyn College include US senators, federal judges, US financial chairmen, Olympians, CEOs, and recipients of Academy Awards, Emmy Awards, Pulitzer Prizes, and Nobel Prizes. College history Early decades Brooklyn College was founded in 1930. That year, as directed by the New York City Board of Higher Educati ...
