Surface modification of polymers and paints is a popular and effective way to enhance the properties of these materials. This can be achieved by introducing a thin coating that preserves the bulk properties of the material, while protecting it from environmental exposure. Suitable materials for such coating technologies are inorganic oxides, such as alumina, titania and silica; however, the fat...

We characterize individual Ag-TCNQ nanocrystals during switching their resistivity state in operando. Raman and soft X-ray absorption microspectroscopy are employed to disclose the electronic state of the organic component in dependency of applied voltage. Whereas Raman microspectroscopy offers qualitative insight into the conversion of negatively charged TCNQ molecules to their neutral counter...

Raman microspectroscopy is a noninvasive, label-free, and single-cell technology for biochemical analysis of individual mammalian cells, organelles, bacteria, viruses, and nanoparticles. Chemical information derived from a Raman spectrum provides comprehensive and intrinsic information (e.g., nucleic acids, protein, carbohydrates, and lipids) of single cells without the need of any external lab...

In situ synchrotron infrared microspectroscopy on single crystals of SAPO-34 reveals that a carbene insertion mechanism is responsible for the first carbon–carbon bond formation from surface methoxy groups.

Synchrotron-based Fourier-transform infrared (FTIR) microspectroscopy was used to distinguish micropopulations of the codominant algae Microcystis aeruginosa (Cyanophyceae) and Ceratium hirundinella (Dinophyceae) in mixed phytoplankton samples taken from the water column of a stratified eutrophic lake (Rostherne Mere, UK). FTIR spectra of the two algae showed a closely similar sequence of 10 ba...

www.spectroscopyonl ine.com espite recent advances in Fourier transform-infrared (FT-IR) microspectroscopy and micro-attenuated total reflectance (ATR), for many types of samples there remains a need for even higher spatial resolution, or for a nondestructive method of recording localized mid-IR spectra from asreceived samples without the risk of damage or alteration by preparation techniques. ...
