The film 23 Pieces can be seen on Virgin Media's TV on-demand service across the UK, thanks to collaboration between Virgin Media, Film Flex Movies and First Light Movies, the National Lottery funded film-making initiative.

The film was made by Thomas Hardye pupils and looks at how genetics affect our life through the story of a boy who is seeking his true identity.

Peter Snelling, film director at PVA Media Lab, said: "We are really excited about 23 Pieces being screened on Virgin Media TV - it is a fantastic opportunity for the children who have worked so hard on this project.

This will take the film to a much wider audience and it is great to see young people's work celebrated in this way." Pip Eldridge, chief executive of First Light Movies, said: "These young film-makers in Dorchester are really gifted and it's fantastic that Virgin Media and Film Flex is showcasing their work on its 'on demand' service.

Atomic layer deposition (ALD) is a thin film deposition technique that is based on the sequential use of a gas phase chemical process.

ALD is considered a subclass of chemical vapour deposition.

The majority of ALD reactions use two chemicals, typically called precursors.

These precursors react with the surface of a material one at a time in a sequential, self-limiting, manner.

Through the repeated exposure to separate precursors, a thin film is slowly deposited.

ALD is a key process in the fabrication of semiconductor devices, and part of the set of tools available for the synthesis of nanomaterials.

Atomic Layer Deposition (ALD) is a thin film deposition method in which a film is grown on a substrate by exposing its surface to alternate gaseous species (typically referred to as precursors).

In contrast to chemical vapor deposition, the precursors are never present simultaneously in the reactor, but they are inserted as a series of sequential, non-overlapping pulses.

In each of these pulses the precursor molecules react with the surface in a self-limiting way, so that the reaction terminates once all the reactive sites on the surface are consumed.
