Using time-, energy- and angular-resolved photoelectron imaging a team of researchers has been able to make snapshots of coupled Rydberg orbitals evolving in time during an ultrafast autoionisation process.
IRsweep’s IRcell is a multipass cell for optical trace gas sensing.
Much of the exterior surface of plants is covered by the cuticle. This plays a vital role in protecting the plant from water loss, attack by pests and pathogens and damage from UV radiation. Infrared spectroscopy is very useful in characterising cuticles, as we learn in “Infrared spectroscopy as a tool to study plant cuticles” by José Heredia-Guerrero, José Benítez, Eva Domínguez, Ilker Bayer, Roberto Cingolani, Athanassia Athanassioua and Antonio Heredia. The authors point out that, whilst still in its early stages, infrared spectroscopy has provided valuable information about the functional groups, chemical structure and arrangement and interactions of plant cuticle components.
Dates and fates of pyrogenic carbon: using spectroscopy to understand a “missing” global carbon sink
Research into climate change takes many directions, but storing carbon or understanding its release from stores is extremely important. Philippa Ascough, Michael Bird, Will Meredith and Colin Snape tell us about “Dates and fates of pyrogenic carbon: using spectroscopy to understand a “missing” global carbon sink”. Pyrogenic carbon comes from the incomplete burning of biomass, and can be natural, e.g. wild fires, or man-made, e.g. the production of charcoal. The authors describe the uses of a range of spectroscopy techniques to understand the molecular structure of pyrogenic carbon and its role in the global carbon cycle..
Entries for the IRDG Chalmers and Dent Student Travel Award for a PhD to present their research at the SciX meeting.
Axiom Analytical has introduced the DMD-373 diamond ATR probe, which is similar to the existing DMD-370 but in a smaller (23 mm) diameter.
Axiom Analytical’s new DPR-212 ATR probe offers similar advantages to their DPR-210 ATR probe but in a straight, 30-cm long configuration designed to provide optical transmission of over 20%.
This product focus is on Molecular Spectroscopy.
Raman, FT-IR and ED XRF discover interesting detail of the dying in the 19th century, and maybe about trade links between Europe and Australia.
First Data Management has released the ATR Drug Kit for rapid screening of street drugs.
Telops’ Hyper-Cam Methane is an imaging Fourier Transform Infrared (FT-IR) spectrometer for remote sensing of methane (CH4).
Specac have introduced the Pearl, a high-specification, liquid transmission accessory for mid-IR and NIR sample analysis in the lab
A new infrared light source with unprecedented sensitivity allows molecular fingerprints of cancer cells.
Ultrafast infrared spectroscopy has shown that long-lived sub-structures exist in liquid water by measuring the vibrations of the O–H bonds.
Fourier transform infrared spectroscopy and imaging of dragonfly, damselfly and cicada wing membranes
Mark Tobin and colleagues describe “Fourier transform infrared spectroscopy and imaging of dragonfly, damselfly and cicada wing membranes”. Insects and plants have evolved highly specialised surfaces such as being highly water repellent or superhydrophobic, which also confers self cleaning properties. This is of interest to materials scientists to help in the development of manufactured materials with similar properties. High spatial resolution FT-IR spectroscopy and imaging provide useful information about the complex chemical patterning that contributes to this functionality.
A microscope being developed at the US Department of Energy’s Oak Ridge National Laboratory will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and beneath the surface.
Diseases like Alzheimer’s are caused when proteins aggregate and clump together. Using atomic force microscopy and infrared spectroscopy, EPFL scientists have successfully distinguished between the disease-causing aggregation forms of proteins. The finding can help change pharmaceutical treatment of neurodegenerative diseases.
The Center for Structural Biology and Bioinformatics at the Free University of Brussels (Université Libre de Bruxelles, ULB) has developed expertise in the analysis of biological molecules using infrared spectroscopy. Now, with the help of Scottish microarray instrumentation company, Arrayjet, the Center has integrated microarray technology to speed up and enhance the analysis of bio molecules such as proteins, which are exposed to hundreds of experimental conditions on a single chip using infrared imaging.
Berkeley Lab researchers’ novel diffraction spectroscopy technique will provide insight to chemical processes at important battery interface.
