An academic-industrial consortium based at the University ofCalifornia in San Diego is launching a three-year research program aimed atdeveloping the world’s first plastic highway bridge, a 450-foot span madeentirely from glass-,carbon,and polymer-fiber-reinforced composite mate-rials, the stuff of military aircraft. It will cross Interstate 5 to connect thetwo sides of the school’s campus.展开更多

Although concrete is an excellent building material because of its abili-ty to withstand stress and compression, it is susceptible to cracking. Car-olyn Dry, an associate professor of architecture at the University of
Instead of using dye to color cotton, an Arizona cotton breeder is letting nature do the work. Through crossbreeding, Sally Fox of Natural Cotton Colours in Wickenberg is creating plants that yield fiber in an
San Francisco’s U.S. Court of Appeals building is the most ornate structure west of the Mississippi River.When it reopens in 1995, it may also be one of the safest.
The benefits of using ceramic engine components are well known:They are tougher than metal parts, weigh less, and can withstand hotter operating temperatures.So why aren’t they being used now? High cost.
A typical food-processing plant produces about 500,000 gallons of waste water daily. Laden with organic compounds, this water usually is evaporated or discharged into sewers.A better solution is to filter the water
