Scientists at Kao Corp. (KAO; Tokyo, Japan; chemical.kao.com) have discovered an enzyme that has the potential for producing large quantities of medium-chain (C12) fatty acids (FAs), which are the main components of natural oils, such as palm-kernel and coconut-palm oils. Such FAs are precursors to surfactants used in shampoos and detergents. The discovery could lead to an alternative route to such...

  CO2-to-syngas . . . Scientists from the University of Illinois at Chicago ( www.uic.edu) have developed a catalytic system — molybdenum disulfide and an ionic liquid — to convert CO2 into synthesis gas, (syngas; a mixture of CO and H2 that is used for making liquid fuels and chemicals, such as methanol). Unlike alternative CO2-reduction processes, which only generate CO, the new catalyst...
