Vendor column: Qualitative models and their application to mining – “How you gonna get any gold if you’re not diggin’?”
Date: Jun 13, 2012
Author: Daniel Shiley
This is the second of a four-part series on chemometric applications for materials analysis. Those of you who have watched the “Gold Rush Alaska” television show on the Discovery Channel might recognize the quote. This is an old attitude, much different than today’s commercial mining companies, which are all very concerned with obtaining information before they begin to dig. The data derived from near-infrared (NIR) analysis often plays an important role in development of this much needed data.

Breathe easy: A bedside test for sepsis
Date: May 15, 2012
Author: David Bradley
Cheminformatics work on Ion Mobility Spectrometry (IMS) demonstrates that, in an animal model at least, the exhaled breath can be used as an accurate, fast and simple point-of-care tool for the diagnosis and monitoring of sepsis.

Journal Highlight: Modeling the combustion of high molecular weight fuels by a functional group approach
Date: May 4, 2012
Author:
A novel approach is proposed for the simulation of the combustion of high molecular weight fuels, wherein the fuel surrogate is defined in terms of pseudospecies including the functional groups contained in the actual fuel, illustrated for linear and branched alkanes.

Herbal acid: Poisonous remedy revealed
Date: Apr 30, 2012
Author: David Bradley
An informatics approach to toxic epidemiology has revealed that aristolochic acid (AA) leads to kidney failure and upper urinary tract cancer (UUC) in individuals exposed to the toxin. AA is found in some plant species that have been used in herbal medicine for centuries.

Caffeinated caffeine: Spotting the synthetic
Date: Mar 15, 2012
Author: David Bradley
Analysis of spectroscopic information has allowed researchers in Germany to determine whether a beverage contains natural or synthetic caffeine. The technique could let regulators check how well manufacturers of added-caffeine products are adhering to the rules regarding labelling products as "natural" with respect to the drink's caffeine content.
