A group of Chemists from the University of Leicester have developed a way of purifying biodiesel made from vegetable oils, which is cheap, simple and low in toxicity.
The team, led by Professor Andrew Abbott is able to remove glycerol, the main by-product of vegetable oil-based biodiesel, using ionic liquids made in part by vitamin B4 (choline chloride).
If left in biodiesel, glycerol (a syrupy sugar alcohol) would damage engines but this technique simply washes it out of the fuel. The ionic liquid developed by Professor Abbott uses a complex of choline chloride with glycerol to extract more glycerol out of the biodiesel.
The Leicester process is greener than traditional processes and effectively provides a sustainable methodology for the purification of biodiesel without the production of significant waste.
Professor Abbott commented: “We hope that further research will optimise the ionic liquid recycling and recovery of the glycerol. We are hoping to collaborate with a biodiesel producer to test this technology further.”

Removing fossil fuel subsidies will not reduce CO2 emissions as much as hoped

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
