Why is cloning such hot science? What are the potential benefits? And are there other ways of achieving them? What are stem cells, and why do many scientists say that embryonic cells are required for this work?

Toyo University Bio-Nanotechnology Symposium Lectures; Dr Woolfson talks on the self-assembly of peptides.

Dr. Tonomura is a world renowned pioneer and authority in the field of electron holography, for which he has received many national and international recognitions. He is recognized for his contributions in the development of electron holography, the ....

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....

The second part of an interview with a very remarkable man.

The first part of an interview with a very remarkable man.

The concluding part of an interview with the 1962 Nobel Laureate in Chemistry.

An archive interview with the winner of the 1965 Nobel Prize in Medicine

The Buckyball, or C-60 molecule was discovered by accident (in the lab) while trying to understand the chemistry between the stars in the Interstellar Medium ISM. The discovery led to the Nobel Prize in chemistry in 1996. Here we look at the structur....

Light is reflected off a flexible shiny surface fixed to the end of a plastic tube. When one speaks into the tubes sound vibrations pass down the tube and make the surface vibrate. The reflected light is therefore sent off from the surface in a con....

When two different types of conductors are pushed into a potato chemical reactions take place charging them up - we have a simple electrochemical cell. A potato, zinc screw and carbon rod produce about 1V. We experiment joining a few of these cells u....

This clip is about solder (a low melting point metal mixture) that can be melted using a hand-held soldering iron. The solder also has flux within it to help combat corrosion and produce a good solder joint to the components and circuitry.

This is a simple yet effective demonstration of electricity generation. 500 turns of wire are wound onto a 35mm film can and the two ends are attached to an LED light. A strong magnet is placed in the can and the lid fixed back in place. The generato....

When two different metals are placed in a salt solution (an electrolyte) the chemistry produces a voltage. This is called a cell. By wiring up a number of these cells we can make a battery and use it to power electrical circuits.

Converting wind power into electricity seems like an ideal way of helping to solve our energy problems. However, the power generated by a windmill is dependent on the wind speed. If the wind drops to half its speed there is as little as an 1/8th of t....

Parabolic surfaces can be used to concentrate energy for example to focus sunlight to heat things. Using an old World War II spot light mirror we demonstrate how easy it it is to concentrate enough energy to cause combustion. Finally, we show how to ....

A workshop in Chemistry at Old Trafford.

Harry Kroto and Jonathan Hare give a workshop at the University of Sussex to local school children and simultaneously video conference with children at Leicester, Imperial, Cardiff, and Edinburgh universities.

A short video explaining how to measure temperature.

John Murrell explains scales and colour changes with temperature, boiling and melting,

Some minerals such as quartz can produce electricity simply by squeezing or bending them - these are called piezoelectric crystals. Here is a simple and cheap demonstration you can do.

Although essentially a very simple device the Gieger Counter is an exquisitely sensitive detector of ionising radiation. It can detect a single particle. Here we demonstrate its use in detecting radiation from minerals and describe in simple terms ho....

A Breathtaking Journey into the Innermost Structure of our Universe.  Runner up: Best use of Animation and Best Short Documentary for the 2002 International Festival of Cinema and Technology.

The Women in Nanotechnology project (WomenInNano) was a 3 year EU Research Project with the aim of finding out ways to support and encourage women working in Nanotechnology. In 2008 the Vega Science Trust was asked to make a short film documenting th....

This short documentary explains why the Large Hadron Collider was built and what scientists are using the collider to look for.

Dr Tara Shears explains why scientists are convinced that Dark Matter exists and how a new experiment called the Large Hadron Collider might finally tell us exactly what this mysterious missing mass is made of.

If equal amounts of matter and anitmatter were created at the birth of the universe then why does our universe seem to be made almost entirely from matter? Dr Tara Shears tells us how this mystery could be explained by the Large Hadron Collider exper....

Dr Brian Cox takes us on a tour of the Large Hadron Collider where the conditions moments after the Big Bang are to be recreated.

Dr Tara Shears explains that one of Science's greatest achievements is to have accurately measured everything from the width of the universe to the diameter of a quark. This film features an animated zoom in from the universe to the heart of a hydrog....

The Large Hadron Collider at CERN is the biggest science experiment ever built. Scientists from all over the world are heading to CERN with the aim of recreating particles from the beginning of the universe. Dr Brian Cox takes us on a scientific jour....
