Much of the chemical industry is based on processes that were developed decades ago.  The change in the cost of petroleum carbon and energy sources and the need to control emissions of carbon dioxide and other pollutants will change the rules of the....

Crystallography has been one of the mature sciences.  Over the years, the modern science of crystallography that started by experimenting with x-ray diffraction from crystals in 1912, has developed a major paradigm that all crystals are ordered and ....

The discovery of superconductivity in hole doped La2CuO4 was motivated by the interest to find this phenomenon in an oxide.  After the discovery near 35 K, copper oxides with transition temperatures of up to 131 K at normal pressure were found, i.e.....

This presentation compares the mechanical properties of bulk- and nano-silicon.

The choice of material for anodes in cells is often of critical importance to their functioning.  This talk looks in detail at their behaviour at the atomic level.

Jonathan describes the production of thin films of mixed polymers by the spin-coating method.  His detection methods include the fluoro-optostrobometer.

How the production of new polymers has made long- and skate-boarding possible.

Using solar cells to convert sunlight to electricity is an attractive way to reduce carbon emissions, but solar cells are still too expensive to be installed on the scale required. The next generation of solar cells aim to solve this problem using st....

The world faces the fundamental problems of increasing waste and decreasing resources as it tries to cope with the increasing consumption of a growing population.  It is clear that these challenges can only be met through a fundamentally different a....

Sustainability is not just about carbon or carbon dioxide, it is also about the sustainable use of the planet's finite mineral and material resources. The availability, affordability and sustainable of supply of a number of important chemical element....

Dr Richard Miller, Head of Sustainability at the UK's Technology Strategy Board, speaks about the problems we are facing in our cities and current ways in which these are being addressed.  He gives examples of how chemists and small-medium sized ent....

In the 21st century, even the toughest of metals are now being replaced by synthetic carbon-based materials that are so strong, light, and resistant to high temperatures that they can be used in the construction of high-performance aircraft.  How....
