Fishnet invisibility cloak
Date: Sep 1, 2008
Author: David Bradley
It is what fans of science fiction and technologists have been waiting for since HG Wells' Invisible Man first came into view - or not, as the case may be. Scientists at the University of California, Berkeley, have engineered three-dimensional metamaterials that can reverse the natural direction of visible and near-infrared light, which could one day lead to an invisibility device.
Read MoreFTIR protein secondary structure analysis of human ascending aortic tissues
Date: Aug 4, 2008
Author:
FTIR microscopy coupled to a curve-fitting procedure has been used to analyze secondary structure modifications in elastin and collagen in human normal and pathological aortic tissues.

Date: Aug 1, 2008
Author: David Bradley
IR spectroscopy of soil fertilised with farm manure reveals that soil quality can be improved significantly compared to "traditional" modern inorganic farming methods and allow poor quality land to be farmed..
Read MoreUse of mid-IR spectroscopy in the diffuse-reflectance mode for the prediction of the composition of organic matter in soil and litter
Date: Jul 3, 2008
Author:
The ability of MIRS to predict the chemical and biological properties of organic matter in soils and litter was studied for 56 samples from agricultural and forest sites. The spectra included part of the near-infrared region (7000-400 cm-1).
Read MoreRock on carbon
Date: Jul 1, 2008
Author: David Bradley
New insights offered by near infrared spectroscopy into the mineralogy of carbonate rocks could help improve the outlook for carbon capture and storage in efforts to reduce the effect of carbon dioxide emissions on the global climate.
Read MoreFTIR microspectroscopic analysis of drug effects on oxidative stress and brain protein structure
Date: Jun 2, 2008
Author:
Lipid peroxidation and protein beta-sheet formation in different brain areas of rats treated with nicotine and/or D(+)-amphetamine have been monitored using infrared microspectroscopy.

Date: Jun 1, 2008
Author: David Bradley
Near infra-red spectroscopy could be use to analyse cowpats and help farmers improve the diet and so yields from their livestock, according to new work to be published in the journal Animal Feed Science & Technology.
Read MoreIR spectroscopy of H(MeOH)n+ clusters in the liquid phase: evidence for a proton wire
Date: May 5, 2008
Author:
The long-standing problem of understanding the nature of the excess proton in acidified water is simplified by studying the proton in methanol by IR spectroscopy. The data indicate that a chain of up to four O-H-O bonds can act as an electrical wire to separate positive charge.
Read MoreFancy ants for arthritis
Date: May 1, 2008
Author: David Bradley
Ants are perhaps not the first organism one would turn to for medical assistance, but researchers in Hong Kong and Japan have now used IR and NMR spectroscopy to study the absolute structures of compounds extracted from Chinese medicinal ants that are thought to have anti-arthritic activity and be beneficial in treating hepatitis.
Read MoreA novel ATR-FTIR method for functionalised surface characterisation
Date: Apr 6, 2008
Author:
A novel method for analysing ex situ-prepared chips by ATR-FTIR circumvents tedious functionalisation steps of internal reflection elements and simultaneously allows for complementary measurements by other analytical techniques.
