CCLRC Daresbury Laboratory

DARTS is a unique service offering solutions to materials characterisation problems that are unattainable in the conventional laboratory. This is possible because it makes use of the Synchrotron Radiation Source (SRS). Advantages of using the SRS include:

New research to evaluate options for a commercial synchrotron analysis service at CCLRC Daresbury Laboratory
02 December, 2005
Intertek Caleb Brett has been appointed by CCLRC Daresbury Laboratory to conduct market research and to evaluate all options for establishing a sustainable synchrotron radiation service for industry. Under details recently announced by CCLRC, the use of the Daresbury Synchrotron Radiation Source by UK academia is planned for phased reduction completing at the end of 2008 and this creates an opportunity for the capacity released to be made more available for commercial use.
Higthroughput new X-ray powder diffraction
27 September, 2005
Following discussions with STOE, Darmstadt 's prestige designer of scientific instruments, DARTS commissioned a bespoke automatic sample changer for use on the high flux powder diffraction station 9.1. Customers working in speciality chemicals and pharmaceuticals will particularly benefit from the high throughput for phase or polymorph identification, structure analysis and combinatorial chemistry studies, where the high intensity of synchrotron radiation is essential.
e-HTPX: e-Science resource for high-throughput protein crystallography
02 September, 2005
DARTS is preparing to offer yet another service to science and industry, namely e-HTPX; an e-science resource for high-throughput protein crystallography. e-HTPX will provide an automated procedure for protein structure determination using X-ray crystallography in a high throughput mode. In addition, e-HTPX will provide access to instruments, databases and low-cost, high quality parallel computing.
DARTS helps solve industrial problems
01 September, 2005
With support from the Victorian Government's new Industry Synchrotron Access, Cetec, a risk management consulting group, contacted DARTS in order to help solve a manufacturing problem for MtM Pty Ltd, an Australian car exporter. Cetec and Mtm Pty Ltd had already used conventional analyses to determine that the problem lay in the bonding mechanism between the bright-metal-on-plastic components. Results suggested that the bonding process could be improved by modifying several stages of the process, but the distribution of metals and other elements below one part per million could not be determined without the use of a synchrotron radiation source.
Crystal structure connected to product performance
01 June, 2005
The appearance of different crystal structures (also known as polymorphs) in a crystallising substance can be critical to its performance in use. During manufacture, process control factors such as pressure and rate of cooling determine the composition of polymorphs that will occur. The ability to look at the detailed crystal structures developing during the manufacturing process allows an understanding of how the presence or absence of a particular polymorph can alter the behaviour, appearance, texture and other characteristics of the finished product. The properties which different polymorphs confer are often the key to improved or diminished product performance in terms of efficacy, safety and bio-availability.
New non-destructive residual stress mapping technique
23 February, 2005
The need of designers, manufacturers and maintenance engineers for non-destructive techniques to assess areas of structural weakness and potential failure in critical engineering components is being met by the DARTS team using the synchrotron at Daresbury Laboratory. Synchrotron strain scanning has been developed into an advanced non-destructive engineering analysis tool using the high energy, high flux beams and large experimental area at the Daresbury synchrotron to characterise the strength and potential failure of structural components. Detailed two and three dimensional strain maps of entire engineering components are obtained faster, to greater depth and more accurately than possible by any other method.
New commissioned beamlines on the SRS
29 November, 2004
MPW6.2 is one of the most recently commissioned beamlines on the SRS and has been optimised to be particularly powerful for the investigation of structural changes during time-resolved materials processing experiments.
New MPW MAD10 beamline has successfully completed its commissioning program
29 November, 2004
The new MPW MAD10 beamline has successfully completed its commissioning program during AP42 (March-October 2004). The station is characterized by the new MAR desktop beamline with CryoSampleChanger capable of storing up to 19 samples at time. The DTB has been integrated with the MAR225 Mosaic detector for macromolecular crystallography and by the C-TRAIN solid state fluorescence detector for MAD/EXAFS experiments.
New beamlines at the SRS
11 November, 2004
Beamline 11.1 is a new synchrotron infrared microspectroscopy facility that has recently been completed at Daresbury, and is now being commissioned ready for access by users. The beamline focuses the infrared synchrotron light down to a 10 micron spot which allows high spatial resolution chemical analysis of a wide range of materials from biological tissues to polymers, and from single crystals to archaeological remains. It is anticipated that the beamline will be further enhanced in the near future by the addition of an array detector infrared imaging system.
Cause of the haziness affecting a transparent polymer food packaging material was discovered
04 November, 2004
The cause of the haziness affecting a transparent polymer food packaging material was discovered by DARTS by combining two complementary techniques available on the synchrotron. Transparent packaging suits both consumers, who can see what they are buying, and manufacturers who can use the visual appeal of the product to entice the customer. However, if the package looks imperfect or deteriorates in storage then this advantage is negated. The polymer film in question consisted of a core of polypropylene with a 0.6 micron surface layer of random copolymer of propylene and ethylene. The haze effect was known to be caused by the scattering of light from crystallites, but more information about the exact nature and size of these crystallites was needed in order to eradicate the problem.

DARTS improves process control through formulation characterisation
29 September, 2004
Using the skill and expertise of the DARTS team and the high intensity X-rays produced by the Daresbury synchrotron, a major player in the oil industry has been able to improve the formulation control of its oil additive quickly and effectively.
DARTS meets the challenge in complex crystal structure determination
09 September, 2004
Patients in the future may be recovering much more quickly from surgery with the introduction of a new molecule which suppresses the effects of the neuromuscular blockers often used in conjunction with anaesthetics.
DARTS new protein crystallisation service
01 October, 2003
Pharmaceutical companies are in the business of producing drugs designed to interact with specific protein targets. The drug/target interaction is first tested in order to elicit an effect, either boosting the protein's biological activity or reducing it. To fine tune the interaction, further detailed information is usually required, which often means structure determination of the protein coupled to its target molecule. DARTS is well disposed to offer a complete protein crystallisation service to satisfy your needs.
New angle X-ray scattering at Daresbury Laboratory can be used to measure size distribution of true nanoparticles
14 July, 2003
Small angle X-ray scattering at the Daresbury Laboratory can now be used to measure the size distribution of 'true' nanoparticles in the 1-100 nm range, using specific experimental conditions and advanced data treatment developed on site. The technique has the flexibility to cope with samples either in liquid suspension or dry powder form, and most importantly can determine particle size distribution, a key requirement of particle size analysis on this scale.
