Summary: This study reports the first experimental demonstration of incorporating the new generation 2D material, MXene, into rare-earth-free oxide perovskite and its effect on thermoelectric performance. The addition of MXene improves the electron mobility and delocalization, resulting in a significant increase in electrical conductivity and power factor. The MXene also leads to lower lattice thermal conductivity through anharmonicity, resulting in a 700% enhancement in the figure of merit (ZT). Furthermore, a thermoelectric generator prototype using only n-type STN + MXene achieves a higher power output than previous oxide thermoelectric generators.

Summary: A metal-free synthetic approach to functionalized indenes using graphene oxide (GO) is presented in this article. The method involves intramolecular Friedel-Crafts-type allylic alkylations with Morita-Baylis-Hillman alcohols. Experimental and spectroscopic investigations were conducted to understand the reaction mechanism involving a nanostructured carbon material-based C-C bond forming reaction. The results showed that this carbocatalysis approach is a viable option for the synthesis of indenes, with a wide scope and moderate to high yield under mild reaction conditions.

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.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
