Mercury 2013 – RSC Award and themed collection

RSC journals were delighted to support the recent International Conference on Mercury as a Global Pollutant which was held in Edinburgh, UK. Congratulations to James Goacher from University of Western Ontario in London, Canada, who was awarded the RSC Best Student Presentation Award in the field of analytical methodology, environmental monitoring and assessment.

James is currently studying at the University of Western Ontario in London, Canada. He began his academic journey by completing a fourth year honours thesis project in the same field and went on to win best thesis presentation for his work. James then began an MSc to focus on historical trends in mercury accumulation in remote peatlands of far Northern Ontario in the Hudson Bay Lowland. This environmentally sensitive area is expected to be subject to some of the greatest climate related changes in the coming future and James feels strongly that area needs to be well understood and protected for its inherent value. By better understanding historical mercury trends in the natural environment, James hopes to tease apart current anthropogenic influences on the mercury cycle so that realistic emissions targets can be set. Future plans for James are still uncertain, but he expects his passion for the environment will lead him on to improve Canadian environmental policy and practises.

We are also pleased to announce that the  following RSC journals will be publishing a cross journal web-themed issue relating to papers presented at Mercury 2013:

Analytical Methods  – Early applied demonstrations of new analytical methods with clear societal impact

JAAS  – Innovative research on the fundamental theory and application of spectrometric techniques

Metallomics  – A global approach to metals in biology

Environmental Science: Processes and Impacts  – advancing our understanding of environmental hazards, processes, and impacts, and offer solutions to today’s and future problems, formerly the  Journal of Environmental Monitoring,

RSC Advances  – An international journal to further the chemical sciences

Authors from the participating sessions are invited to submit to the journal most suitable for their work. The relevant articles from the conference will be published in those journals and then collected together as a joint web collection, as a permanent record of the conference. Articles submitted to the participating journals will be reviewed in the usual manner, and also appear in a normal issue both online and in print.

The submission deadline for our web theme will be September 24th 2013 with the view of final publication in January 2014. Specific information on the scope of each journal and author submission instructions can be found on the journal homepages.

We look forward to receiving your submission!

Forensic fingers

A team in the US has developed a detection system that crime scene investigators can wear on their fingertips to rapidly identify suspected traces of explosives and gunshot residue.

With the increase in crimes related to explosives and firearms, fast and accurate detection of possible traces of explosives and gunshot residue is of considerable importance. Forensic analysis is typically carried out in a central laboratory, requiring time-consuming sampling, transportation and storage. Joseph Wang and colleagues at the University California, San Diego, have built on their expertise with wearable sensors  to move forensic analysis away from the lab and to the crime scene.

Their new sensor is made up of two components: an electrode screen-printed onto a stretchable sheath worn on the index finger and a second sheath, worn on the thumb, coated with a solid-state ionogel electrolyte. ‘Initially we intended to use a hydrogel, but the lifetime of this media was finite due to evaporation of water,’ says Wang. The ionogel circumvents the need for carrying additional liquid reagents, making the device highly portable.

Solid-state Forensic Finger sensor for integrated sampling and detection of gunshot residue and explosives: towards ‘Lab-on-a-finger’
Amay J. Bandodkar, Aoife M. O’Mahony, Julian Ramírez, Izabela A. Samek, Sean M. Anderson, Joshua R. Windmiller and Joseph Wang   Analyst, 2013, Advance Article
DOI: 10.1039/C3AN01179H

Protein analysis unlocks museum mysteries

Animal soft tissues feature regularly in cultural artefacts but it can be difficult to pinpoint their origin. Visual identification of these tissues relies on the skill of the examiner and the condition of the material. Analytical techniques, like gas chromatography-mass spectrometry, can detect and broadly classify proteins but give no answers as to their source. Precise identification of the sinews used for stitching is often impossible. Now, researchers in the US and UK have shown that peptide mass fingerprinting can be used to determine the animal species of collagen-based materials in a diverse range of museum objects.

Peptide mass fingerprinting (PMF) uses enzymes to digest proteins to produce a mixture of peptides. The mass spectrum of this mixture will have characteristic marker ions – called a peptide mass fingerprint – which are compared to a database of species-specific markers to identify the proteins.
