This presentation gives Rowland's current (2006) opinion/impression of Global Warming. He says that the first legislated discussion that he remembers in the US senate on the Global Warming was in 1986 and the looming problem and whether governments s....

Start at 15:00 minutes.  Dr Jeremy Spencer examines the role of flavonoid-rich foods which have been shown to promote a healthy heart and improve our mind and mood.

The ultrahigh mass resolving power and sub-ppm mass accuracy of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) allow the assignment of a unique molecular formula to each peak in the mass spectrum. Ionization methods for petro....

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.

Dr. Kroto talks about his favorite synthesis reaction in chemistry

The palladium-catalyzed cross-coupling reaction between different types of organoboron compounds and various organic halides in the presence of base provides a powerful and general methodology for the formation of carbon-carbon bonds.  The (sp3)C-B ....

Born in Lithuania, Aaron Klug, Nobel Prize in Chemistry, 1982, tells us about his early life and education growing up in Durban, South Africa. He developed an early interest in physiology and anatomy but did not find his teacher very inspiring and ga....

After a short reminder of the historical development of evolutionary biology, elements to a molecular theory of Darwinian evolution will be presented. Biological evolution is driven by the availability of genetic variants in populations. The occasi....

Molecules to observe and manipulate biological systems can be devised by a variety of strategies, ranging from pure chemical design and total synthesis to genome mining and high-throughput directed evolution. Examples of both successes and failures a....

Darryl Ventura presents his research into developing functional carbon nanotube based materials.
