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....

Eighteenth-century chemists could gain useful income and patronage as advisors to industry – and some of the wealthiest and most influential industrialists were brewers. Making chemical knowledge credible to this audience, however, was not always e....

A laboratory demonstration of Carbon Dioxide's effect of global warming.

Professor Monique Simmonds talks about the use of plants and fungi as sources of sustainably harvested medicines

A short Introduction to the Nano2Hybrid European Research Project. A video profiling a nanotechnology research project supported by a European Materials Research grant aims to produce a tiny gas sensor using nanotubes that have been developed to be s....

The Namur group are heading up the nano2hybrids project. They are the specialists in plasma treatment of the carbon nanotubes to activate their surfaces, followed by putting down metal nanoparticles under vacuum. These are then sent to Spain to be ma....

The Louvain-la-Neuve group are specialised in theoretical modelling at the atomic scale of the metal nanoparticles on the carbon nanotube surfaces, and in particular how electronic charge passes through the tubes in this case.

The ULB partner in the project are specialised in plasma surface treatment under air, rather than vacuum - it's the next step up in scaling up the plasma treatment of the nanotubes after the Namur group. In the earlier stages of the project they are ....

The CRPGL group is a newly formed lab in Luxembourg. Within the project their role is to start looking at 'scale up', plasma treatment at larger scales than is possible in the other labs, coupled with a battery of different sample testing techniques.

Institut des Materiaux, Nantes, France. The IMN group are specialists in computer modelling - in this case, of atomic defects and damage in the surface of the carbon nanotubes caused by the plasma treatment. What is the plasma doing to the nanotube s....

The Tarragona Group at University Rovira i Virgili are the experts in producing new prototype gas sensors. All the new metal particle treated nanotube samples from Belgium and Luxembourg make their way down to this beautiful corner of Spain, where th....

Sensotran are the industrial partner in the nano2hybrids project. A small family firm based just outside Barcelona in Spain, they are experts in commercial production of gas sensors for a range of industries, notably for detecting dangerous gases pro....

Dan gives a brief introduction into his group's discovery of a new and efficient catalyst which could be of vital importance in our search for better ways of capturing solar energy.

A moving address by Harry to the ACS meeting in San Francisco about his colleague and fellow Nobel Prize winner, Richard Smalley.

Olefin metathesis is an irresistible way to make C=C bonds catalytically in organic molecules and polymers, both as a consequence of its very nature, i.e. the synthesis of C=C bonds from C=C bonds, and because of the control that can be exercised thr....

Fundamental aspects of Alkaline Fuel Cells

Philip Shlenoff, recent high school graduate, gives a presentation of his work and opportunity at the Florida State University Dept. of Chemistry. Under the supervision of Zaki Estephan, Philip has actively participated in research that targets canc....

Most important applications in the field of fuel cells

Aquaporin channels allow water to rapidly cross cell membranes in all living organisms. AQP1 confers red cells and proximal renal tubules with high water permeability. Present in renal collecting duct, AQP2 is regulated by vasopressin, and human muta....

Peter Agre shared the 2003 Nobel Prize in Chemistry with Roderick MacKinnon “for discoveries concerning channels in cell membranes.” Here he gives a lecture in Russia as part of the Nobel Prize Inspiration Initiative

In thistalk Harry Kroto explains that molecules have structures that are every bit as real in the mind of the chemists who create them, as are the edifices of brick, steel and concrete designed by architects and built by engineers.

A brief history of carbon-60 and its developments into useful materials. How can chemistry help move us towards a more sustainable existence.

Despite their relatively small mass, 10% of the earth biosphere as a whole, generations of ambitious ‘homo sapiens’ have already played a major and increasing role in changing basic properties of the atmosphere and the earth’s surface.  Human ....
