Breakthrough in greener solutions

20.12.2002


Pioneering new solvent systems which are recyclable and environmentally compatible have been developed by researchers at the University of Leicester.



The team, led by Drs Andy Abbott and David Davies, has developed a wide range of new solvents made from bulk commodity materials such as urea (a common fertiliser) and vitamin B4. These have been studied extensively in recent years as they offer a potentially clean way to carry out chemical processes. They are non-volatile whilst liquid over a wide range of temperatures and offer a benign alternative to, for example, some strong acids.

The work has been carried out by the joint venture company, Scionix Ltd, set up by the University with Genacys Ltd, a subsidiary of the Whyte Group Ltd.


Scionix is now marketing a range of these solvents for companies to test on their specific applications.

These novel liquids can be used for a variety of applications including metal finishing, catalysis, batteries and metal reprocessing, to name but a few. Further benefits include limited sensitivity to water, readily available in large quantities and at comparable cost to many volatile organic solvents (VOS).

Dr Abbott said “I think the unusual properties of these fluids combined with their simplicity of manufacture will lead to their rapid adoption as environmentally compatible solvents. For the first time we can subtly alter the properties of a solvent to tailor it to a specific application”.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
