Conventional metalizing and brazing techniques used for Alumina and sapphire are not directly applicable to ALON. However, Surmet has now successfully demonstrated a novel metalizing technique that results in hermetic brazed joints with high strength and durability while preserving ALON´s optical, IR and RF transparency. Mechanical integrity of the braze joint is maintained over a wide range of temperatures. This is a significant development as it enables materials and engineering...

An international team of physicists has developed a method for taking ultrafast “sonograms” that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through an important physical process called a phase transition. Common phase transitions include the melting of candle wax before it burns and dissolving sugar in water. They are purely structural changes that produce dramatic changes in a material´s physical...

University of Texas at Austin researchers have cloaked a three-dimensional object standing in free space for the first time. The researchers used a method known as plasmonic cloaking to hide a 7-inch cylindrical tube from microwaves.  During the study, they were able to show how ordinary objects can be cloaked in their natural environment in all directions and from all vantage points. When using the plasmonic cloaking method, light strikes an object, and rebounds off its surface...

Computational Materials researchers at UC Santa Barbara use cutting-edge calculations to determine fundamental optical transparency limits in conducting oxide material tin oxide Researchers in the Computational Materials Group at the University of California, Santa Barbara (UCSB) have uncovered the fundamental limits on optical transparency in the class of materials known as transparent conducting oxides. Their discovery will support development of energy efficiency improvements for...

Corundum is the crystalline form of aluminium oxide and one of the rock-forming minerals. Corundum is naturally clear, but can have different colors when impurities are added. Transparent specimens are used as gems, called ruby if red, while all other colors are called sapphire. The word corundum comes from the Hindi kurand. The oxygen atoms in corundum are arranged in a hexagonal close-packing, with the smaller aluminium atoms occupying 2/3 of the octahedral gaps. The coordination of the...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
