• Selecting Makeup Gas for GC with FID (.pdf)
  . can produce makeup. In contrast, a number of serious hazards exist when. nitrogen with purity. makeup gas is supplied to the GC via a tank. As an example,. of better than 99.9999 if the contents of a full tank of helium or nitrogen were sud-. percent with respect. denly vented into the laboratory, up...
• Certifying gas distribution systems in a fab producing advanced-technology devices
  fittings. To ensure they will not contaminate the gas, cylinders are electropolished, cleaned, and passivated internally, then filled with UHP nitrogen for certification based on the collection of particle data. They may be reinspected before reuse to review the passivation condition, but since...
• Invention could solve bottleneck in developing pollution-free cars
  condenses into a liquid at -252 C. This makes it difficult to use conventional storage systems. High-pressure gas containers would need 3-in.-thick steel walls, making them too heavy and large for cars. Scientists have experimented with ways of storing hydrogen by locking the gas into metal lattices...
• Farm Waste for Fuel Tanks
  the raw material for more than 10 million cars per year." A test pickup truck, part of a fleet of more than 200 natural gas vehicles, has been in use since mid-October. Researchers are monitoring mileage range per fill-up, pressure and temperature of the tank during charging/discharging, charging...
• Leland Teschler's Editoral: MPG follies
  You might think the Big Three would be the only automakers trying to buck regulations mandating fuel efficiency. Detroit, after all, is synonymous with "gas guzzler." Guess again. Toyota took time off from making Prius hybrids recently to criticize an energy bill passed by the Senate that boosts...
• MICRO:Product Technology News (Oct. '98, p.110)
  The sealed-chamber design of the Portable Clean Room maintains a positive-pressure nitrogen environment for more than three days to protect wafers in transit from molecular contaminants, oxygen, and particulates. Suitable for use with 200-mm wafers, the hand-carried microenvironment normally...
• World's strongest aluminum alloy
  quenched, and transforms from liquid to solid state. Molten metal in an induction furnace flows from a small hole in the bottom of the furnace. Nitrogen gas blows over the molten metal as it exits the furnace, atomizing the material into a fine mist of droplets. The droplets accumulate and solidify...
• Low-pressure molding offers stiff competition
  (such as nitrogen N2) into the thermoplastic resin melt. The gas and plastic dynamically mix under high backpressure inside the extruder barrel of the injection-molding machine (IMM). The gas dissolves forming a homogenous mixture of single-phase solution and microscopic gas bubbles. The resin/gas mixture...
• MICRO: Green Manufacturing
  . Most fabs now recycle significant portions of their ultrapure water (UPW) by collecting wafer rinsewater at the tools and recycling it back to the UPW feed tank. This procedure has resulted in significant water and chemical savings, since the rinsewater is usually of better quality than the water...

  and chamber cleanliness for high yields. It is capable of forming gas, nitrogen, or vacuum levels 0.01 mtorr. The choice of atmospheres accommodates a range of processes, including low oxygen concentration. The atmospheres can also shorten both heating and cooling cycles. Magnet field strength...
