Engineers of the structure propose using ethylene
tetrafluoroethylene (ETFE), a material that weighs only a fraction as much as glass and can withstand 180 mile per hour winds.
It combines a double O-ring-sealed packing follower with low-friction
tetrafluoroethylene (TFE)-based packing materials for reliable, long-term service that complies with low-emissions standards, www.masoneilan.com.
trifluorostyrene) and also in case of grafting onto polymer substrates of high radiation sensitivity such as poly(
tetrafluoroethylene) (PTFE).
In section drawings, curling arrows indicate air convection currents and exchanges through the tent's chimney and through a breathable membrane of ETFE (ethylene
tetrafluoroethylene), a lightweight recyclable plastic film, with better light transmission than glass, that will envelop the structure.
The steel-looped Beijing National Stadium, for instance, includes a rainwater collection arrangement, a natural ventilation system and a clear roof with inflatable cushions made from ETFE (Ethylene
Tetrafluoroethylene), a kind of plastic that increases light and heat penetration.
The Cube's approximately 4,000 bubbles are made of high-tech ethylene
tetrafluoroethylene (ETFE), a sturdy material that is 1/100th the weight of glass.
The many stadiums China has erected to host the Olympic events are considered green marvels, including the steel-looped Beijing National Stadium, or "Bird's Nest" which includes rainwater collection, a natural ventilation system and a clear roof with inflatable ETFE cushions (made of Ethylene
Tetrafluoroethylene, a kind of plastic) and the steel "Water Cube" for aquatics events, which is completely surrounded with ETFE pillows that increase light and heat penetration, cutting energy use by 30 percent.
Fluon ETFE (a copolymer of ethylene and
tetrafluoroethylene) is a high-performance fluoropolymer developed by Asahi Glass, which in 1975 became the world's first company to begin commercial production of the material.
A portion of the eluted sample was diluted 1:10 in matrix solution, and 1 [micro]L of the resulting mixture was spotted on a SCOUT 600-[micro]m AnchorChip target (Bruker Daltonics), a sample support coated with a strongly water-repellent layer of poly(
tetrafluoroethylene) (Teflon) harboring an array of small spots acting as hydrophilic sample anchors and holding the sample droplets in place during solvent evaporation.
Examples of topics discussed include the atomic- scale interaction of bioactive glasses with simulated body fluid, optical activity of deuterated analog of L-arginine phosphate single crystals, measurements of zeta potential of poly(
tetrafluoroethylene) foils, x-ray photoelectron spectroscopy study of copper tellurite glasses, estimation of selenium consumption during selenization of Cu-In metallic layer in a quasi-closed system, radiation-induced- defects localization in single-mode optical fibers, and characterization by electron diffraction of two thermodynamical phases of precipitation in Nb-microalloyed steels.
