Microbial Life beneath a High Arctic Glacier | Applied …

The debris-rich basal ice layers of a high Arctic glacier were shown to contain metabolically diverse microbes that could be cultured oligotrophically at low temperatures (0.3 to 4°C). These organisms included aerobic chemoheterotrophs and anaerobic nitrate reducers, sulfate reducers, and methanogens. Colonies purified from subglacial samples at 4°C appeared to be predominantly psychrophilic.

Different Types of Fuses and their Appliions

2  · Some of these types are also used in other high-power circuits. 3. RESETTABLE FUSES/POLYFUSE Like their name suggests, these fuses are self-resetting. They contain carbon black particles eedded in organic polymers. Normally, the carbon black makes the mixture conductive. When a large current flows, heat is generated which expands the organic

It is applied in mascara as a volumizing agent. In hair styling products, carnauba wax imparts hold.

Solvated Electrons in High-Temperature Melts and …

Solvated electrons in alkali metal-ammonia solutions have attracted attention as a prototype electronic conductor and chemical reducing agent for over a century. However, solvated electrons have not been realized in a high-temperature melt or glass of an oxide system to date. We demonstrated the formation of persistent solvated electrons in both a high-temperature melt and its glass by using

To reduce the melting point of silica, it is necessary to add a flux; this is the purpose of the sodium carbonate (soda ash), which makes available the fluxing agent sodium oxide. By adding about 25 percent of the sodium oxide to silica, the melting point is reduced from 1,723 to 850 °C (3,133 to 1,562 °F).

Strategic Materials

The metal is hard, silvery-white in color, and very light — less than twice as dense as water, and only two-thirds as dense as aluminum, which it somewhat reseles. Beryllium has a very high melting point at 1,287°C (2,349°F). The coination of its light weight and high melting point make it valuable for making metal alloys.
