Today, we're going #BehindTheScenes with a video about how we prepare a sample for Differential Scanning Calorimetry, a test method used for measuring the thermal behavior of materials. #MaterialsScience #MaterialsEngineering #ScienceCommunication

In spite of their high sensitivity and self-referencing features, are plasmonic tilted fiber Bragg gratings "difficult" to fabricate and use? Not any more! It is shown in this article published in collaboration with groups in Belgium (Caucheteur and Loyez), and Spain (Villatoro) that when a single deposition of metal on one side of the standard single mode fiber is used, it is no longer necessary to polarize the interrogating light source: the transmission spectrum is made up of an interleaved comb of highly sensitive resonances and totally unsensitive ones. This allows for spectrally localized, self-referenced measurements of biosensing events at the fiber surface, and improved accuracy through averaging of multiple resonance shifts.

If you have heated oil in a pan, you might have seen convection currents in the form of regularish polygonal patterns. Did you know that thin fluid films that are heated from below, can also deform in regular patterns and that spots may even dry out? Together with Gabriele Brüll and Bastian Hilder, we have studied these thermocapillary thin films and proved the existence of such regular patterns and film-rupture solutions.

Application News of the Month ⭐🗓️ The AIRsight Infrared/Raman Microscope is a unique microscope that combines both infrared and Raman spectroscopy into a single instrument, offering complementary molecular information. In this application, we conducted measurements of iron oxide and oxyhydroxide, the main causes of rust. It was found that the spectra of inorganic compounds, which are difficult to detect with infrared measurements, can be obtained through Raman measurements. Since Raman measurements can confirm the functional groups of metal oxides, it is possible to qualitatively identify the types of rust. Additionally, in fluorescent X-ray measurements, peaks at different energy positions for each element can be observed, allowing for a multifaceted evaluation of the metals.

#OneTechnologyAMonth series Sept 2024 - Laser diffraction Citing one of Alan Rawle's top words of wisdom: "Like most things in life one gets out what one puts in" Did you know that typical instrument related standard error in a laser diffraction measurement is less than 1% regardless of particle size? The main sources of error are: 1. Dispersion - especially important for particle sizes less than 1 micron 2. Sampling - especially important for particle sizes larger than 100 microns (image from Dr. Henk Merkus, "Quality assurance in particle size measurements" 1997)

Integrated color cameras allow researchers to “see into each reactor,” even if they are not there.   See profile reaction texture, i.e., homogeneous vs. heterogeneous with separated oil or solid phases, and see solid characteristics.   This is really important since about 70% of reactions are heterogeneous and changes in the characteristics of reaction solids can be important to process understanding and scale up. #reactall #reactionscreening #reactionprofiling #reactionkinetics #routescouting #processchemistry #processchemist #synthesis #reactions #chemicalreactions

The integrated color cameras in ReactALL™ provide invaluable insights into the reaction texture, and allow scientists to continuously monitor the ongoing reaction. In this short video, you can see the images captured during an experiment.
