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....

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....

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....

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....

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.....

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 ....

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 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 ....

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....

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....

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....
