Polyglycolic acid (PGA) has good properties: a very high gas impermeability, even under 80% humidity; biodegrability; high mechanical strength; and good moldability, which makes it a promising polymer for applications such as medical devices and barrier films. But up to now, it has been difficult to make large quantities of the material. Kureha Corp. (Tokyo, Japan; edlinks.che.com/7371-536) has developed a...

Although theoretically promising 80% more energy than is required to grow and convert to cellulosic ethanol, switchgrass has proven to be a difficult fuel source to break down cost effectively. With $1 million from the U.S. Depts. of Agriculture (USDA) and Energy (DOE), a team led by Professor Alan Weimer of the...

Sugar-beet processors in the U.S. generate approximately 40 million tons of fiber-rich sugar-beet pulp every year as a byproduct of sucrose extraction. Most of it is used as livestock feed or in pet food. Researchers with the U.S. Agricultural Research Service (ARS; edlinks.che.com/7371-542) are working on a process to convert the pulp into a filler for polylactic-acid-based plastics (PLA)...

In cooperation with several universities, Clariant International Ltd. (Muttenz, Switzerland; edlinks.che.com/7371-543) has developed a process to manufacture high-quality nano-sized zeolite L (Linde Type L) in technical quantities. This new range of nano-scale aluminosilicates, tradenamed Lucidot, open up a new range of possibilities in biochemical processes, including molecular sieves, ion...

High-pressure die-cast (HPDC) aluminum alloys cannot normally be heated to high temperatures due to the presence of pores containing entrapped gases, which lead to the formation of surface blisters. CSIRO Materials Science and Engineering (Melbourne, Australia; edlinks.che.com/7371-548) has found that blistering can be avoided by using shorter solution-treatment times at lower temperatures. CSIRO says its...

Despite challenges created by a building frenzy in the Middle East and Asia, E&C firms continue to deliver new chemical facilities around the world Anyone with an ear to the door of the chemical process industries (CPI) knows that the rising cost of raw materials is forcing processors to chase the cheap feedstocks. The relatively low price of oil and natural gas is making plant investments in the...

Fuel cells and hydrogen economy are inevitably used in the same breath when talking about clean power and ways to wean us from our addiction to carbon-based fuels. That’s because H2 -based fuel cells make electricity and heat with only water in the exhaust. Unfortunately, realistic assessments of the current situation conclude that it will be awhile — perhaps decades — before hydrogen...

The Seebeck effect — the direct conversion of a temperature difference to electricity — is responsible for the operation of thermocouples. But taking advantage of this phenomenon to make electricity from waste heat in so-called thermoelectric (TE) devices has been hindered by the high cost or toxicity of common TE materials, such as lead-tellurium or cobalt-antimony. And up to now, production...

The standard way to test for toxicity in individuals who have been exposed to heavy metals is to take a blood sample and analyze it in the laboratory by plasma mass spectrometry, an expensive and time-consuming procedure. Now, a portable instrument that can do the same job in the field in 2 – 5 min, for one-tenth the cost, has been developed at Pacific Northwest National Laboratory (PNNL, Richland...
