“…A detailed analysis of the data obtained through confocal microscopy was performed using Mountains Map Premium software (Digital Surf, France). To present the effect of isotonic drinks on the change in the surface geometry (SGS), Ra and Rz parameters were selected [15]. Ra is the arithmetic mean of the absolute departures of the roughness profile from the main line while Rz is the mean value of the maximum peak to valley height of the profile within the sampling lengths.…”

“…The PSLS measurements were made using a LabRam™ Confocal Raman Microscope (Jobin-Yvon/Horiba, Edison, NJ0) [30]. a-Al 2 O 3 is known to strongly fluoresce in response to visible laser illumination if trace quantities of chromium are present, giving a peak doublet (R1-R2) at around 693 nm [31].…”

Effect of environmental sulfur on the structure of alumina scales formed on Ni-base alloys

a b s t r a c tShort-term oxidation exposures of an alumina-scale forming c 0 -Ni 3 Al-based model alloy in air and O 2 + 0.1%SO 2 at 900°C revealed that the presence of sulfur can affect the kinetic competition between the h and a structural isomorphs of Al 2 O 3 . After 2 h exposure, metastable h-Al 2 O 3 growth predominated in air alone; whereas, a much larger percentage of stable a-Al 2 O 3 formed during oxidation in O 2 + 0.1%SO 2 . This promotion of a-Al 2 O 3 establishment was due to sulfur enrichment on the alloy surface, which occurred even when samples were exposed to O 2 + 0.1%SO 2 in a low-temperature, pre-test position ($150°C), i.e., prior to insertion into the hot zone. It was determined from XPS measurements that the sulfur was mainly in the S 6+ valence state and, correspondingly, in the form of NiSO 4 . Cross-sectional scanning transmission electron microscopy (STEM) using energy-dispersive X-ray spectroscopy (EDS) corroborated the XPS results by detecting that a $20 nm zone of sulfur enrichment within the surface region of a $90 nm oxygen-rich layer formed during the pre-test exposure. A systematic explanation for this intriguing observation of sulfur promoting a-Al 2 O 3 establishment is provided from the perspective of kinetics competition between h and a. This explanation was supported by kinetic calculations and complementary tests in a low p O 2 atmosphere.

“…Confocal laser scanning microscopy has been primarily developed to image cells, proteins, or other biological machines tagged with a fluorophore. 44 The technique is also of interest for studies in materials science, 45 albeit rarely used so far.…”

Time-Lapse, in Situ Imaging of Ice Crystal Growth Using Confocal Microscopy

et al. 2016

Ice crystals nucleate and grow when a water solution is cooled below its freezing point. The growth velocities and morphologies of the ice crystals depend on many parameters, such as the temperature of ice growth, the melting temperature, and the interactions of solutes with the growing crystals. Three types of morphologies may appear: dendritic, cellular (or fingerlike), or the faceted equilibrium form. Understanding and controlling which type of morphology is formed is essential in several domains, from biology to geophysics and materials science. Obtaining, in situ, three dimensional observations without introducing artifacts due to the experimental technique is nevertheless challenging. Here we show how we can use laser scanning confocal microscopy to follow in real-time the growth of smoothed and faceted ice crystals in zirconium acetate solutions. Both qualitative and quantitative observations can be made. In particular, we can precisely measure the lateral growth velocity of the crystals, a measure otherwise difficult to obtain. Such observations should help us understand the influence of the parameters that control the growth of ice crystals in various systems.
