first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round. However‚ no practical use was made of the discovery for several decades. Independently‚ Oleg Vladimirovich Losev published "Luminous carborundum [[silicon carbide]] detector and detection with crystals" in the Russian journal Telegrafiya i Telefoniya bez Provodov (Wireless Telegraphy and Telephony). Losev ’s work languished for decades. The first practical LED was invented by Nick Holonyak

lucrative product. But I always imagine the art of manufacturing behind it and awe the people and machineries involved in the job. My fascination for Industrial Engineering began during my sophomore year when I went to my first industrial visit to Carborundum Universal‚ I found some answers to my curiosity. But it never satisfied my curiosity. Then I questioned how these works‚ process‚ machines‚ workers and hierarchy of orders involve. How these companies know what to do? When to do? And how all of

Abrasive flow machining 1. Introduction Abrasive flow machining (AFM) was firstly developed fifty years ago by Extrude Hone Corporation‚ USA. By using the liquid viscoelastic material with easy flowability made of polymer and abrasive grains‚ AFM can be used to polish‚ deburr and radius for the workpiece. There are three kinds of AFM: one-way AFM‚ two-way AFM and orbital AFM [1]. In this case to manufacture the cylinder heads‚ consider of two-way AFM is much more widely used and its technology

Another piece of evidence recorded is the fact that monotid bivalves went extinct in the lower Kennecott Point section where the researchers also studied.

Silicon dioxide (SiO2) is one of the most common oxides on the surface of earth. Like most oxides‚ it adopts a polymeric structure. Оксидите се хемиски соединенија што содржат најмалку еден атом на кислород и еден атом од друг хемиски елемент во својата формула. An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygenatom and one other element[1] in its chemical formula. Metal oxides typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth’s crustconsists
