Isotope signature identifies yellowcake origin

09 Oct 2013

A new way to determine the source of nuclear materials has been developed by nuclear forensic scientists in Germany and South Korea. The sulfur isotope ratio in uranium ore concentrate gives an identifiable signature that depends on the origin of the ore and how it was processed.

Nuclear forensics is the analysis of nuclear materials, with a view to determining their heritage. This information can be used in conjunction with law enforcement and intelligence information to find individuals and organisations responsible for the illicit proliferation of nuclear material, or those planning nuclear terrorism.

European Symposium on Atomic Spectrometry ESAS 2014 & 15th Czech-Slovak Spectroscopic Conference

02 Oct 2013

European Symposium on Atomic Spectrometry

ESAS is the international meeting of scientists to share recent developments, exchange ideas, explore new directions and initiate a possible collaboration in the atomic spectrometry area. Leading scientists and researchers will be invited to present their most up-to-date results at this conference, to exchange exciting ideas and experiences as well as look into future development.

Czech – Slovak Spectroscopy Conference

CSSC brings together experts from Czech and Slovak universities, academia, official centers, various laboratories, and industry on a world-wide scale, to summarize the current progress in different areas of spectroscopy and the trends in the applications such as chemical, environmental, geological, biological, food, pharmaceutical and industrial materials and to stimulate contacts and mutual exchange of experiences and ideas.

Key dates

Registration and payment deadline November 30, 2013

Submission of conference papers May 15, 2014

Venue

Prague – historical pearl of Europe – is one of the most beautiful cities in the world. Since 1992 the historical core of the city covering 866 hectares has been listed in the UNESCO World Cultural and Natural Heritage.

Usually Prague is called “golden” and “a hundred towers”, but it is sure, that it belongs amongst the most beautiful cities in the world. The charming river Vltava, which enhances the city´s beauty, forms wreathes resembled to silver string. Many of the city´s dominants are reflected in the river, towers, the cathedral dome, the palace and many houses,greeness of the gardens and islands. www.praguecityline.cz

Plumage patterns in a 150 million year old bird revealed

13 Jun 2013

Manning et al., J. Anal. At. Spectrom., 2013,28, 1024-1030

Archaeopteryx lithographica single feather, visible light and SRS-XRF false colour images

Researchers at the University of Manchester discovered that the world’s oldest bird was not black, as previously thought.

Phillip Manning and colleagues used synchrotron rapid scanning X-ray fluorescence (SRS-XRF) combined with sulphur X-ray absorption near edge structure (XANES) to examine the presence of trace elements in the feathers of Archaeopteryx, an iconic fossil widely studied to understand bird evolution.

The importance of colour of in the natural selection of bird plumage was first acknowledged by Charles Darwin. The colour of bird plumage is in fact a function of selection processes, varies depending on age, sex, diet and is crucial for camouflage and marking the territories.

This study suggests a “possible visual role for pigments in the feathers of Archaeopteryx acting as a fitness criterion in the natural selection of this species, and having an impact on evolution of pigmentation in this and other feathered theropod dinosaurs”, write the authors.

The paper, ‘Synchrotron-based chemical imaging reveals plumage patterns in a 150 million year old bird’, was published in the themed issue of JAAS on Elemental Imaging and has featured in an article in the Daily Mail today. This paper will be free to read for 6 weeks.

Gordon F. Kirkbright Bursary Award, 2014

09 May 2013

The Gordon F. Kirkbright bursary award is a prestigious annual award that enables a promising student/non-tenured young scientist of any nation to attend a recognised scientific meeting or visit a place of learning.
The fund for this bursary was established in 1985 as a memorial to Professor Gordon Kirkbright in recognition of his contributions to analytical spectroscopy and to science in general. Although the fund is administered by the Association of British Spectroscopists (ABS) Trust, the award is not restricted to spectroscopists.

Applications are invited for the 2014 Gordon Kirkbright Bursary.

For further information contact John Chalmers at, email: vibspecconsult@aol.com

The closing date for entries is 31 December 2013.
