Aluminium oxynitride is the hardest polycrystalline transparent ceramic available commercially. [ 2 ] [ needs update ] Because of its relatively low weight, distinctive optical and mechanical properties, and resistance to oxidation or radiation, it shows promise for applications such as bulletproof , blast-resistant, and optoelectronic windows ...
Transparent armor is a material or system of materials designed to be optically transparent, yet protect from fragmentation or ballistic impacts. The primary requirement for a transparent armor system is to not only defeat the designated threat but also provide a multi-hit capability with minimized distortion of surrounding areas.
A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one letter, while the black squares are used to ...

(Refractive index is the ratio of the speed of light in vacuum to the speed of light in a given medium. The refractive index of vacuum is therefore 1.) The larger the refractive index, the more slowly light travels in that medium. Typical values for core and cladding of an optical fiber are 1.48 and 1.46, respectively. [citation needed]
Smaller words may be easier to fit in the grid, but longer words give more clues to connecting words. [ 10 ] Care must be given to marking out words that are not explicitly placed in the grid; this occurs when one fills in a vertical sequence of horizontal words, or vice versa.
WSB-TV reports that under Georgia law, third-party lien holders must notify you within 60 days of assuming your debt and can charge you a one-time 10% penalty, with 1% interest accruing each month.
Transparent exopolymer particles (TEPs) are extracellular acidic polysaccharides produced by phytoplankton and bacteria in saltwater, freshwater, and wastewater. [1] They are incredibly abundant and play a significant role in biogeochemical cycling of carbon and other elements in water. [ 2 ]
