journal of applied physics & nanotechnology impact factor
Journal of Applied Physics The Journal of Applied Physics is a peer-reviewed scientific journal with a focus on the physics of modern technology. The journal was originally established in 1931 under the name of Physics, and was published by the American Physical Society for its first 7 volumes. In January 1937, ownership was transferred to the American Institute of Physics "in line with the efforts of the American Physical Society to enhance the standing of physics as a profession".[1] The journal's current editor-in-chief is AndrÃ© Anders (Lawrence Berkeley National Laboratory). According to the 2015 Journal Citation Reports, the journal has a 2016 impact factor of 2.068.[2]
Atom The physicist J. J. Thomson measured the mass of cathode rays, showing they were made of particles, but were around 1800 times lighter than the lightest atom, hydrogen. Therefore, they were not atoms, but a new particle, the first subatomic particle to be discovered, which he originally called "corpuscle" but was later named electron, after particles postulated by George Johnstone Stoney in 1874. He also showed they were identical to particles given off by photoelectric and radioactive materials.[9] It was quickly recognized that they are the particles that carry electric currents in metal wires, and carry the negative electric charge within atoms. Thomson was given the 1906 Nobel Prize in Physics for this work. Thus he overturned the belief that atoms are the indivisible, ultimate particles of matter.[10] Thomson also incorrectly postulated that the low mass, negatively charged electrons were distributed throughout the atom in a uniform sea of positive charge. This became known as the plum pudding model.
