Coordination polymers are a fantastically diverse class of molecular materials. Here we look at a few examples of their unique structures and properties.

Making a coordination polymer is a complicated process with many potential variables. Here we look at the advantages of a few different synthesis methods.

Exploiting the unique properties of coordination polymers requires full understanding of their formation. Here we look at how in-situ x-ray diffraction helps to uncover some of the details.

Intermittently fluorescing single molecule systems are found in many materials, including semiconductor quantum dots (QD), dyes on crystalline or nanoparticle film surfaces, and biological systems. The QD's show a ~ -3/2 power law for the distributio....

Quasicrystals - or, as Shechtman would prefer, quasi-periodic materials - now have scientists thinking about matter in a new light, but they also have many possible practical applications. Because of their uneven structure, quasicrystals do not have ....

Aki decribes her experiments in improving soils using various buffering materials.

What do six brides have to do with Density-Functional Theory? Discover it in this lecture, in which the essential ideas behind DFT are explained in three different non-technical ways. After this practical lecture, you will be able to understand the m....

When he received the 1996 Nobel Prize in Chemistry together with Richard E. Smalley (who also worked at Rice) and Sir Harold Kroto (at the time at the University of Sussex, UK), this was a true example of national and international scientific collabo....

Prof. Kroto starts his lecture with remarks on his boyhood and his passions at school and University, especially graphic art and drawing.  He mentions his 4/5 rule and shows the connection between theory and experiments, and he is sold on scientific....

The fact that our modern world is so completely and precariously balanced on Science, Engineering and Technology (SET) makes an understanding of these disciplines by all in positions of significant responsibility vital. lthough wise decision-making ....

Chemistry is not merely a science of making observations in order to better understand Nature. Our science is creative and productive, generating substances of very high value from almost nothing. Chemists already have made enormous contribution to....

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 Ð that all crystals are ordered an....

Until recently, most of the 24 d-block transition metals had been used primarily as useful materials for (i) construction and also as tools and containers, etc., (Ti, Zr, Fe and their alloys with V, Cr, Mn, Co, Ni, etc.), (ii) precious and ornamental....

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....

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.....

Jonathan Christian discusses what it means to be a material/physical chemist. He shows how a physical chemist characterizes materials using his research into Chromium 3+ polyoxometalates.

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.

Aby describes his research into novel nanomaterials.

How do we choose the right materials for tall buildings?

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

Ramya talks about the ways in which nanomaterials can affect rice-plant growth and also be used for imaging purposes.  This talk was part of her PhD thesis defence.

Brahatheeswaran describes how tissue scaffolds can be made in novel ways.  This lecture is his PhD thesis defence.

During his PhD thesis defence, Ankur looks at the ways in which various techniques are used for the creation of the desired structural characteristics of carbon nanotubes  

Srivani describes in her PhD dissertation lecture how silica nano-materials can be used in both the imaging and treatment of cancer-related angiogenesis.

With the aid of Prof. Sir Harry Kroto, Dr Peter Wothers demonstrates that both Diamond and Graphite are indeed made of Carbon.

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 science of carbon nanotubes and related materials. How can we use them to make novel hybrid structures?

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....
