In this interview Sherwood Rowland talks about Ozone depletion and the effect of CFCs on Ozone and Global Warming (Greenhouse Warming where infrared radiation is trapped). He explains the chemistry of Ozone depletion and the history of what led to th....

Why is carbon sequestration so important?

This lecture addresses the question if spatio-temporal self-organisation of matter which is so characteristic for living systems can also be verified with a simple inorganic reaction in which the observed phenomena of complexity can be traced back to....

An introduction into the writing down of fully balanced chemical equations. The process is explained starting with word equations, finding all the relevant formulas and then working with some useful rules for finding the correct coefficients in the b....

Heeger says that he started as a physicist and thinks like a physicist but got interested in the late 70's in the study of materials. For him it was a natural evolution to move to polymers and in 1975 he began working with Alan MacDiarmid and became ....

An introduction to constructing and recognising chemical formulas. Using 20 well-known elements, the valency-rules which govern the atomic ratios are explained and used with several examples.

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....

We are faced with energy challenges and the promise of power with hydrogen. The fuel cell and solid state hydrogen storage methodologies are currently limited by materials and represent the cutting edge of energy technology. Implementation to a real ....

A workshop in Chemistry at Old Trafford.

Early rare earth metals (La, Ce, Pr, Nd) combined with late first row transition metals (Fe, Co, Ni) can produce low melting eutectic mixtures. For instance, a 75:25 mole percent mixture of La and Ni forms a eutectic that melts at 532 õC. We are inv....

Jess gives a lively account of her work which involves the study of how uranium organ-metallics can catalyse unusual and useful reactions.  She is a PhD student at the University of Sussex, UK.

The concept of oxidation and reduction is explained and generalised using oxidation numbers with ionic and covalent examples. Several equations are balanced, using the oxidation number method to fix various atomic ratios.
