Small, EarlyView.Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

Depth-resolved whole-field displacement measurement using wavelength scanning interferometry [PDF]
, 2004 We describe a technique for measuring depth-resolved displacement fields within a 3-dimensional (3-D) scattering medium based on wavelength scanning interferometry. Sequences of 2-dimensional interferograms are recorded whilst the wavelength of the laser

Small Methods, EarlyView.Differential phase contrast (DPC) imaging in STEM is demonstrated as a rapid, versatile segmentation tool for advanced aluminum alloys. Decomposition of false‐color DPC micrographs resolves nanoclusters, precipitate variants, dislocation strain fields, nanostructures, and grain boundaries ‐ all within a single and fast acquisition.

Externally Dispersed Interferometry For Terrestrial Exoplanet Detection
, 2011 Terrestrial exoplanets are observationally challenging to detect and characterize. Compared to gas giant exoplanets, terrestrial exoplanets introduce significantly smaller radial velocity signals and transit depths on their host stars. The signals are larger for terrestrial exoplanets orbiting M-dwarf stars, which have lower masses and radii than Sun ...

Non-linear Sagnac interferometry for pump-probe dispersion spectroscopy
, 2003 We explore pump-probe non-linear Sagnac interferometry as a tool to measure the dispersive properties of a medium. We introduce the background theory, and show experimental spectra obtained on the D2 transition with 85Rb and 87Rb.

steel research international, EarlyView.Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Improvements to dispersed reference interferometry: beyond the linear approximation
Applied Optics, 2018 Interferometric instruments with dispersion introduced in the reference arm have previously been created, as the controlled dispersion can be used to generate a signal that contains a clearly identifiable point, the location of which relates to the position of the scattering surface in the measurement arm.

VIEW, EarlyView.Mitochrial transplantation is a promising therapy to restore energy in damaged cells, but it lacks fast and reliable methods to assess mitochondrial quality before use. In this study, we used a label‐free imaging technique called interferometric light microscopy to rapidly measure the size and concentration of isolated mitochondria.
