Abstract: A method is disclosed for forming a film of an amorphous material, for example amorphous silicon, on a substrate (14), by deposition from a plasma. A substrate is placed in an enclosure having a defined volume, and a film precursor gas, for example silane, is introduced into the enclosure through pipes (20).

Abstract: A method is described of forming a film of an amorphous material on a substrate (14) by deposition from a plasma. The substrate (14) is placed in an enclosure, a film precursor gas is introduced into the enclosure through pipes (20), and unreacted and dissociated gas is extracted from the enclosure through pipes (22) so as to provide a low pressure therein. Microwave energy—is introduced into the gas within the enclosure as a sequence of pulses at a given frequency and power level to produce a plasma therein by distributed electron cyclotron resonance (DECR) and cause material to be deposited from the plasma on the substrate. The frequency and/or power level of the pulses is altered during the course of deposition of material, so as to cause the bandgap to vary over the thickness of the deposited material.

Abstract: A method for labeling acyl carrier protein (ACP) fusion proteins with a wide variety of different labels is disclosed. The method relies on the transfer of a label from a coenzyme A type substrate to an ACP fusion protein using a holo-acyl carrier protein synthase (ACPS) or a homologue thereof. The method allows detecting and manipulating the fusion protein, both in vitro and in vivo, by attaching molecules to the fusion proteins that introduce a new physical or chemical property to the fusion protein. Examples of such labels are, among others, spectroscopic probes or reporter molecules, affinity tags, molecules generating reactive radicals, cross-linkers, ligands mediating protein-protein interactions or molecules suitable for the immobilization of the fusion protein.
