Summary: This paper demonstrates a simple method to calibrate attenuated total internal reflection infrared absorbance measurement using a commonly available reference sample such as water. The calibration takes into consideration the polarization of the incident beam and the spread of angles about the nominal angle of incidence. The calibrated measurements enable quantitative comparison with spectra calculated from optical constants, and the method is applied to temperature-dependent absorption spectra of a polydimethylsiloxane sample, showing better correlation between the extracted optical constants and temperature-dependent changes in polymer density than the raw absorbance values on vibrational resonance.

Summary: Amphiphilic copolymer micelles are promising nanocarriers for hydrophobic drugs and imaging agents due to their self-assembling properties. They have advantages such as therapeutic efficacy, diagnostic sensitivity, and controlled release to the desired tissues. Their smaller particle size and modified surfaces help to accumulate easily in the target location, enhancing cellular uptake and reducing unwanted side effects. Stimuli-sensitive micelles can trigger the release of encapsulated agents.

Summary: This perspective discusses the use of Raman spectroscopy to interpret surface-selective vibrational spectra in bulk aqueous phases. By overcoming the limitations of spectral fitting, it provides an experimental route for analyzing spectral features, even in cases with only a single set of beam polarizations. Two-dimensional correlation analysis is used as a general method, with a specific application to vibrational spectra. The combination of sum-frequency and Raman data allows for unraveling characteristic features of aqueous interfaces, such as the surface preference of adsorbed species relative to their bulk concentration.

Summary: We present a basic theoretical treatment of selectively probing film-substrate and substrate-environment interfaces in a visible-infrared sum frequency generation experiment by controlling film thickness and beam angles. We also account for the unique optical properties of the interfacial environment. Using the glass-polydimethylsiloxane-air system as an example, we model the electric fields at both surfaces of the polymer. We also provide practical considerations for setting up such experiments and present typical experimental results.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
