Technology to cool down global warming
Article Abstract:
Carbon dioxide sequestration is being studied as a solution to global warming. The Louisiana State University (LSU) is studying two methods of sequestering CO2. In carbonation, cement absorbs CO2 while it is curing. In the second method, algae on pH-neutral cement built as artificial reefs uses CO2 during photosynthesis. This methods keep CO2 within their systems indefinitely, reducing CO2 levels in the atmosphere. The LSU is also developing a type of cement that will hasten algae attachment to reduce the surface area available for non-photosynthesis participants. The US Department of Energy is sponsoring LSU's research.

Atomic-emission spectroscopy goes online, on a stack
Article Abstract:
Massachusetts Institute of Technology and Pacific Northwest National Laboratory have developed a system, that combines microwave plasma with atomic-emission spectroscopy. The stack-mounted system is a measurement device for determining the trace metals content of hot exhaust gases. Testing of the measuring equipment was conducted at the US Environmental Protection Agency's facilities at Research Triangle Park, NC. A microwave waveguide feeds from the stack a continuous slipstream, which is heated by the plasma to 5,000 degree Centigrade. The plasma is operated at 2.45 GHz and 1.5kW.

Yeast ferment starch in one step
Article Abstract:
Biomedical Sciences Institute and the Polytechnical School, both of the University of Sao Paulo in Brazil, have genetically engineered a new yeast that could produce ethanol from starch in one step. Alpha amylase and glucoamylase genes were inserted into Saccharomyces cerevisiae yeast. The genes enable the yeast to process ethanol in one step promising cost savings. Test results on cassava starch at the 5-L scale show ethanol produced in the regular process is equivalent to the amount produced by the new yeast.
