Happy New Year! Our first issue of 2012 is now online for you to read.
On the front cover is work from Daniel Attinger of Columbia University, New York, USA and his colleagues from other US institutions.
Their study proposes that images of stains from 100-nanolitre drops can be automatically identified as signatures of fluid composition and substrate chemistry, which has implications for areas such as biological testing.
They used classification algorithms to identify unknown stains, and demonstrated a high level of accuracy.

On the cover of the latest issue of Analytical Methods is a minireview from Kate Griffiths and colleagues at the Australian National Measurement Institute.
When using quantitative PCR, a calibration curve is commonly constructed from serial dilution of a reference DNA preparation and the test material is quantified by comparison to the curve. There are many factors in this process that can affect the accuracy of the measured value, and there have been some efforts to standardise or optimise this technique as there is ample evidence of measurement inconsistencies.
Here, Griffiths et al. present a relatively simple process for estimating measurement uncertainty for quantitative DNA measurements produced by qPCR, with a worked example.

Issue 9 front cover: Gregson et al.
In the latest issue of Analytical Methods, three articles are highlighted on the covers.
On the front cover is work from Robin Taylor and colleagues of the National Nuclear Laboratory, at various sites across the UK.
There are a number of nuclear legacy fuel storage ponds and silos in the UK that contain substantial volumes of corroding spent Magnox fuel pieces. Understanding the nature and behaviour of the radionuclides in the ponds, including any potential for activity transfer from solid to solution phases, is critical in the environmental clean-up of these nuclear legacy facilities. The results presented in this paper indicate that Pu redox chemistry, and therefore solubility, varies across the pond, which has implications for Pu behaviour during waste processing.

They investigated the thermal decomposition of Japanese lacquer liquid and films by means of evolved gas analysis-ion attachment mass spectrometry. Their results indicated two stages of water release, vaporization and intramolecular H2O elimination, and the kinetics of these two processes were studied.
