Xinsheng Zheng and colleagues note that an energy-hungry world, concerned about global warming, increasingly puts its future fuel hopes on renewable fuels like biodiesel.
Today's biodiesel production processes, however, require catalysts to speed up the chemical reactions that transform soybean, canola, and other plant oils into diesel fuel. Traditional catalysts cannot be reused and must be neutralized with large amounts of water — another increasingly scarce resource — leaving behind large amounts of polluted wastewater.
The researchers describe development of a new catalyst produced from shrimp shells. In laboratory tests, the shrimp shell catalysts converted canola oil to biodiesel (89 percent conversion in three hours) faster and more efficiently than some conventional catalysts. The new catalysts also can be reused and the process minimizes waste production and pollution, the scientists note.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
