Second Sino-Japanese War
The Second Sino-Japanese War (1937–1945) or War of Resistance (Chinese term) was a military conflict that was primarily waged between the Republic of China and the Empire of Japan. The war made up the Chinese theater of the wider Pacific Theater of the Second World War. The beginning of the war is conventionally dated to the Marco Polo Bridge Incident on 7 July 1937, when a dispute between Japanese and Chinese troops in Peking escalated into a full-scale invasion. Some Chinese historians believe that the Japanese invasion of Manchuria on 18 September 1931 marks the start of the war. This full-scale war between the Chinese and the Empire of Japan is often regarded as the beginning of World War II in Asia. China fought Japan with aid from Nazi Germany, the Soviet Union, United Kingdom and the United States. After the Japanese attacks on Malaya and Pearl Harbor in 1941, the war merged with other conflicts which are generally categorized under those conflicts of World War II a ...

Non-ferrous Metals
In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), non-magnetic properties or resistance to corrosion (e.g. zinc). Some non-ferrous materials are also used in the iron and steel industries. For example, bauxite is used as flux for blast furnaces, while others such as wolframite, pyrolusite, and chromite are used in making ferrous alloys. Important non-ferrous metals include aluminium, copper, lead, tin, titanium, and zinc, and alloys such as brass. Precious metals such as gold, silver, and platinum and exotic or rare metals such as mercury, tungsten, beryllium, bismuth, cerium, cadmium, niobium, indium, gallium, germanium, lithium, selenium, tantalum, tellurium, vanadium, and zirconium are also non-ferrous. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrometallurgy
Pyrometallurgy is a branch of extractive metallurgy. It consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. Pyrometallurgical treatment may produce products able to be sold such as pure metals, or intermediate compounds or alloys, suitable as feed for further processing. Examples of elements extracted by pyrometallurgical processes include the oxides of less reactive elements like iron, copper, zinc, chromium, tin, and manganese. Pyrometallurgical processes are generally grouped into one or more of the following categories: * calcining, * roasting, * smelting, * refining. Most pyrometallurgical processes require energy input to sustain the temperature at which the process takes place. The energy is usually provided in the form of combustion or from electrical heat. When sufficient material is present in the feed to sustain the proce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ye Zhupei
Ye Zhupei or Yap Chu-Phay (; 1902 – 24 November 1971) was a Chinese physical chemist, chemical engineer, and metallurgist. Born into an overseas Chinese family in the Philippines and educated in the United States, he moved to China in the 1930s and served in both the Kuomintang and the Communist governments. Considered the founder of chemical metallurgy in China, he was elected a founding member of the Chinese Academy of Sciences (CAS) in 1955 and established the Institute of Chemical Metallurgy (now Institute of Process Engineering) of the CAS in 1958. He was persecuted during the Cultural Revolution and died in prison after five years of incarceration. Early life and career in the United States Ye Zhupei (or Yap Chu-Phay in Hokkien) was born in 1902 in Manila, American Philippines, into an overseas Chinese family that originated from Xiamen, Fujian. His father, Ye Duxing (), was a businessman and follower of the revolutionary leader Sun Yat-sen. He entered Colorado School o ...
