U of A chemistry team produces a 'game-changing' catalyst

28.09.2011
University of Alberta chemistry researchers have discovered an active catalyst that has the potential to improve the efficiency and environmental impact of manufacturing processes used to make products such as agrochemicals and pharmaceuticals.

The research led by U of A chemistry professor Steven Bergens targeted the organic compounds known as amides, which are raw materials used by many industries to make a variety of chemical products. Bergens and his research team found that combining hydrogen with their new catalyst transforms amides into a variety of desired chemical products efficiently, safety and without potentially environmentally dangerous waste.

The new catalyst is considered to be green because it produces no by-products and it uses hydrogen that can be produced easily by any industry on site. Any excess hydrogen remaining after the reaction can be reused or simply burned to generate water and heating energy. In contrast, the current, conventional method used by industry requires expensive and dangerous shipping of tons of highly flammable, reactive chemicals by truck or rail, and it also produces large amounts of waste that must be removed at added cost and threat to the environment.

Researchers around the world have been working for more than 50 years to find a catalytic system for this vital class of reaction that operates efficiently and produces little to no waste.

Currently industries such agrochemicals and pharmaceuticals must ship huge quantities of highly reactive and flammable chemicals for mass production of their products. The waste produced is expensive to process and can be hazardous to the environment.

Bergens says the discovery of a cheap catalyst with minimal and re-useable waste has the potential to revolutionize the chemical industry from an economic and green perspective.

The work of Bergens and U of A graduate student Jeremy John was published in the journal Angewandte Chemie.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
