Summary: This study investigates a dielectric tube reactor with a single pin electrode for depositing polyaniline thin films. The experimental results show that the configuration of the pin electrode, bluff-body height, and gas flow rate affect the generation of plasma and the deposition of polyaniline. In some cases, intense glow-like plasma generates reactive nitrogen species and excited argon radicals, which contribute to the fragmentation and recombination of polyaniline and result in increased film thickness and deposition rate.

Summary: This study investigates the temporal dynamics of atmospheric-pressure nanosecond pulsed plasma discharges in a pin-to-pin electrode configuration using streak-camera line imaging. The discharge emission starts uniformly throughout the interelectrode gap and then decays in two distinct phases. The plasma emission in air and N-2 environments shows significant differences in their temporal dynamics. The formation and relaxation timescales of electronically excited states of N-2 are quantified with sub-nanosecond resolution. The streak-OES technique allows for quantitative time-resolved studies of key chemical species in ultra-short-pulsed plasmas.

Summary: In this study, a new mechanism for chemically responsive structural colors based on thin-film interference was demonstrated through the charge modulation of conjugated polymers. A liquid-liquid interfacial self-assembly method was utilized to create a flexible, transferable, and highly homogeneous conjugated block copolymer film. The introduction of gold (Au) complexes in the self-assembly process enabled in situ oxidation of conjugated polymers into a hole-polaronic state, rendering the polymer film responsive to the chemical environment. The responsive thin-film colors showed thickness-dependent tunable reflective colors and experienced drastic changes in dielectric behavior upon switching of the polaronic state, allowing for large modulations to the interferometric colors.

Summary: Pulsed-DC DBD is an effective technique for reducing skin friction drag with limited power consumption. The characteristics of pulsed-DC DBD, including power consumption, induced flow structure, thermal effect, and body force, have been investigated. The results show that the power consumption and pressure waves produced by pulsed-DC DBD are similar to that of DBD using nanosecond pulses, while the wall-bounded jet structure resembles that of DBD using sinusoidal high voltage. The induced body force increases with pulse width, while the thermal effect weakens.

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.
