Summary: In this study, Znchitosan aerogels were successfully synthesized and further carbonized to obtain NHPC aerogels. Zn ions acted as activators and soft templates to fabricate hierarchical porous structures in a carbon matrix. The structure and morphology of NHPC could be controlled by adjusting the ratio of zinc-chitosan complexes. The optimal NHPC showed excellent capacity and cycle stability in three-electrode systems, and high energy density and power density in two-electrode systems.

Summary: A unique porous TiO2 with Co3O4 nanoparticles anchored in (Co3O4@TiO2) is prepared by a dual-templating method for promoting electromagnetic microwave absorption. The Co3O4@TiO2-2 with 25 wt % Co3O4 nanoparticles content displays a strong and ultrawide effective absorption band performance, with a reflection loss of -53.9 dB at 2.95 mm and a super broad effective absorption band of around 12.5 GHz at 5.0 mm. The dual-templating approach for a well-controlled porous structure could be a facial strategy for the development of high-performance electromagnetic wave absorbers.

Summary: The intercalation of MoO2-supported nickel nanoparticles (NPs) with a mesoporous carbon layer was achieved through thermal reduction of hierarchical nickel molybdate with Ni2+-polydopamine complex (PDA-Ni2+) coated on its surfaces. High coverage of nickel NPs was achieved from nickel molybdate and a carbonized PDA-Ni2+ layer under the protection of a nitrogen atmosphere. Doping of other transition metals such as cobalt ions has been achieved at the stage of nickel molybdate formation, with the added amount of cobalt ions playing a vital role in tailoring the composition and morphology of the cobalt-doped nickel molybdate.

Summary: In this study, one-dimensional mesoporous tubular g-C3N4 was successfully synthesized using halloysite as a hard template for the first time. The synthesized 1D structure showed enhanced efficiency in degrading tetracycline under visible light, with a higher specific surface area and more active sites compared to traditional g-C3N4. Additionally, the presence of associated carbon from halloysite increased the electron transfer rate, contributing to the accelerated separation of photo-generated carriers and prevention of recombination to enhance photocatalytic activity.

Summary: Converting lignin into high value-added products is crucial for reducing reliance on petroleum resources and environmental protection. This study developed an efficient photocatalytic material (TiO2/g-C3N4@LCNFs) by loading TiO2 and g-C3N4 into lignin-derived carbon nanofibers (LCNFs). The TiO2/g-C3N4@LCNFs achieved a degradation rate of 92.76% for Rhodamine B (RhB) under UV-vis irradiation, demonstrating superior performance compared to other carbon fiber-based photocatalysts. The excellent degradation property can be attributed to the synergistic effect of TiO2 and g-C3N4, enhancing the excitation efficiency and prolonging the lifetime of electron-hole pairs. This work provides guidance for the development of efficient photocatalysts using biomass-derived fiber materials.

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.
