Ellis et al., Analyst, 2012, 137, 1100-1110

Why not take a look at the latest issue of Analyst?

Featured on the front cover is a paper on the use of ambient ozone for the assignment of double bond position in unsaturated lipids. Stephen Blanksby and colleagues from the University of Wollongong, Australia, have made use of the fact that unsaturated lipids react with the low concentrations of ozone present in normal laboratory air.

Unsaturated lipids are deposited onto thin layer chromatography plactes and allowed to undergo ozonolysis. The products are then analysed by desorption electrospray ionization mass spectrometry (DESI-MS), providing unambiguous assignment of double bond positions without the need for instrument modifications.

Sun et al., Analyst, 2012, 137, 1125-1129

The back cover highlights research from Xiangying Sun and co-workers at Huaqiao University, Xiamen, China. They have developmed a novel dual-fluorescence quantum dot (QD) nanocomposite with tuning emission wavelength and fluorescence intensity which can selectively sense mercury ions (Hg²⁺) with a detection limit of 5.6 nM. They propose this can e used for the qualitative and semi-quantitative colorimetric analysis of Hg²⁺.

By Mary Badcock, Deputy Editor.

The latest issue of Analyst is now available online!

In this issue, the front cover features work by Aaron Timperman and colleagues from West Virginia University, USA, who report the fabrication and performance of a microfluidic traveling-wave electrophoresis system, a promising new separation technique. It uses a locally defined traveling electric field wave within a microfluidic channel in order to achieve band transport and separation. The authors anticipate that this technique will open up many future lab-on-a-chip applications, processes and systems.

Fabrication and performance of a microfluidic traveling-wave electrophoresis system, Kyoo D. Jo, Jarrod E. Schiffbauer, Boyd E. Edwards, R. Lloyd Carroll and Aaron T. Timperman, Analyst, 2012, 137, 875-883

The inside front cover of this issue highlights work by Hui-Fen Wu and Kamlesh Shrivas from the National Sun Yat-Sen University, Taiwan, who report the rapid and sensitive protein extraction by cobalt oxide nanoparticle-based liquid-liquid microextraction coupled with MALDI-MS. The show for the first time that the metal oxide nanoparticles prepared in the organic phase can be successfully applied to the extraction and preconcentration of proteins, and their approach offers distinct advantages including high sensitivity for washing and separation-free MALDI-MS analysis of proteins.

Editorial Board member Duncan Graham to receive Coblentz Society Craver Award

25 Jan 2012

By Vibhuti Patel, Deputy Editor.

Professor Duncan Graham

The Coblentz Society has announced that Professor Duncan Graham, Reviews Editor of Analyst, has been selected as recipient of the 2012 Craver Award.

The Craver Award was established in 2006 to recognize the efforts of young professional spectroscopists that have made significant contributions in applied analytical vibrational spectroscopy. The society has named this award for Clara D. Craver in recognition of her pioneering efforts in promoting the practice of infrared vibrational spectroscopy and her many years of service to the Coblentz Society. Previous winners of the Award include another Analyst Editorial Board member, Boris Mizaikoff.

This award is presented to Professor Graham in recognition of his pioneering work in surface enhanced Raman scattering (SERS) to generate ultra-sensitive and highly selective methods of detection for a range of analytes, especially bio-analytical targets.

The Craver Award will be presented at the FACSS annual meeting, newly re-named SCIX, to be held in Kansas City, USA, 30 September – 5 October 2012.

Duncan will present the Coblentz Society’s Craver Award Plenary Lecture in Applied Vibrational Spectroscopy and a separate half-day award symposium of six invited presentations will be held following his lecture at this conference.

Take a look at Duncan’s recent Grand Challenges review below, and contact us if you’d like to discuss the submission of a review to his office.

FACSS Award winners announced

Professor Peter Griffiths, recipient of the 2012 ANACHEM Award

The Federation of Analytical Chemistry & Spectroscopy Societies (FACSS), of which the RSC is a member society, has announced the winners of two awards.

The 2012 ANACHEM Award will be presented to Peter Griffiths, Emeritus Professor at the University of Idaho, USA.

Professor Griffiths completed his Ph.D. at Oxford University in 1967, and has worked in many different aspects of vibrational spectroscopy since then. The research in his laboratory has been largely centered on the application of infrared and Raman spectrometry to the solution of problems of analytical, environmental and structural chemistry.

The Association of Analytical Chemists, ANACHEM, is a non-profit organization dedicated to the general welfare and education of analytical chemists and to the advancement of the theory and practice of analytical chemistry as a profession; it was a founding member of FACSS.

Dr Don Pivonka, recipient of the 2012 Charles Mann Award

The 2012 Charles Mann Award for Analytical Raman Spectroscopy will be presented to Don Pivonka, a senior principal chemist at Incyte Pharmaceuticals.

Dr Pivonka received his Ph.D. in analytical chemistry from Kansas State University, and then went on to work for many organisations including ICI and AstraZeneca. He has been a leader in the use of infrared and Raman spectroscopy within the area of pharmaceutical discovery, and has championed novel applications for understanding relationships between drug candidates and their ligand/receptor interaction in biological systems.

The Charles Mann award for Applied Raman spectroscopy was instituted in 2002 by FACSS following the untimely death of Professor Charles (Charlie) Mann. Professor Mann was a long-standing faculty member at Florida State University, and contributed significantly to the development of analytical Raman spectroscopy.

SCIX 2012, 30 Sep - 04 Oct, 2012

As award recipients, both Peter and Don will give a plenary lectures at the SCIEX conference in Kansas City later this year.

Congratulations!
