Does a one size fits all data life cycle meet laboratory requirements for data integrity? No! The reason is that there are many different types of analytical procedures and this requires a flexible analytical data life cycle.

Infrared microspectroscopy has led to important advances in a wide range of fields, as biologists, chemists, geologists, materials scientists, microscopists, and spectroscopists around the world have awakened to the values of nanotechnology. The small world is getting larger.

In this study, micro-Raman microscopy was used to examine graphite mechanical behavior through the evolution of dislocation defect density and the resultant deformation (strain) in graphite components. The increasing strength of the Raman optical phonon modes linked with a generous number of dislocations indicates the potential capability of Raman spectroscopy to help develop a mechanistic understanding of the complex mechanical behavior of graphite for use in many industries and applications.

Aromatic esters follow the ester Rule of Three, but each of these three peak positions is different for saturated and aromatic esters, which makes them easy to distinguish. Organic carbonates are structurally similar to esters and follow their own Rule of Three.

This article illustrates experience with some new developments in IR spectroscopy, with examples of how this traditional field continues to explode into new territory, enabling rapid acquisition of huge data sets on the one hand, while permitting exploration of chemical composition of targets with nanometer-scale spatial resolution on the other.
