HOT article: Detecting water in fuel

Professor Boris MizaikoffTake a look at this HOT paper from Editorial Board member Boris Mizaikoff.

Water is a common contaminant in industrial oils and petroleum products. It impairs the performance and longevity of machinery, so it’s important to detect it in these products. A previous approach has involved off-site analysis, but this method is time consuming and may be compromised because of the potential variability in water concentration introduced by storage, transportation or shipment of a sample.

Here, Professor Mizaikoff and colleagues have focused on quantifying trace amounts of water in hydrocarbons using hexane as a model system for industrial oils and petroleum using mid-infrared evanescent field absorption spectroscopy.

They used a silver halide fibre optic waveguide to interrogate in situ water-in-hexane emulsions. The limits of detection and limits of quantification of water in hexane using tin-crosslinked polyacrylic acid modified fibres were 76 and 170ppm, respectively. The IR absorption signature of water in hexane was detected at concentrations as low as 10ppm.

The strategy requires a single measurement, requires no sample preparation and has the potential for direct in situ detection.

New Associate Editor for the Americas: Professor Evan Williams

Professor Evan WilliamsWe are delighted to announce the appointment of Professor Evan Williams of the University of California, Berkeley as our second Associate Editor for the Americas.

Professor Williams received his B.S. from the University of Virginia and his Ph.D. from Cornell University; he has held positions at Stanford University and Lawrence Berkeley National Laboratory, been a Visiting Professor at the University of Aarhus, Denmark, and received numerous awards.  His current group at Berkeley develops and applies novel instrumental and computational techniques in mass spectrometry, tandem mass spectrometry, separations, and laser spectroscopy to solve problems of fundamental interest in chemistry and biochemistry.

We’d like to welcome Evan and his expertise to the Analyst Editorial Board as Associate Editor alongside Professor Steve Soper – together, we look forward to further meeting the needs of our authors.

So, if you’re an author in the Americas, why not submit your paper?

Grand challenges in surface enhanced optical spectroscopies

Professor Duncan Graham

Take a look at Analyst Editorial Board member Duncan Graham’s contribution to our ongoing theme on Grand Challenges, which is included as part of Issue 19.

There remain several challenges to overcome in order to achieve widespread clinical use of surface enhanced techniques. In this review, Iain Larmour and Duncan Graham consider the substrates employed to achieve enhancement before reviewing each enhanced optical technique in detail; surface plasmon resonance, localised surface plasmon resonance, surface enhanced fluorescence, surface enhanced infrared absorption spectroscopy and surface enhanced (resonance) Raman spectroscopy.

Thermochemiluminescence patterns act as fingerprints to accurately classify proteins

Albumin solutions were added directly onto each sensing element. When heated, the albumins are thermally oxidised, generating distinct thermochemiluminescence patterns.

We’ve just published the latest paper from Analyst‘s Associate Editor for Asia, Xinrong Zhang, and colleagues from Tsinghua Universtiy, China.  It details an innovative nanomaterial array which uses chacteristic thermochemiluminescence signals to recognise protein subtypes and denatured shapes.

Read the paper for free until 8th September.

We’d like to congratulate our Advisory Board member Professor Christy Haynes who is the 2011 winner of the Joseph Black Award.  This award, sponsored by the Analytical Chemistry Trust Fund, and is presented to a young scientist in any field covering the practice and teaching of analytical science.

Christy, who is an Associate Professor of Chemistry at the University of Minnesota, was awarded for her work on leveraging the core principles of analytical chemistry to gain insight into pressing toxicological, immunological, and ecological questions.

Prof. Haynes is Guest Editor or our upcoming themed issue on Emerging Investigators, alongside Dr Perdita Barran from the University of Edinburgh.  Dr Barran was herself winner of the Joseph Black Award in 2009.  The themed issue will be published later this year, and you can read Christy’s paper for the issue using the link below.
