Summary: The study demonstrates that low-temperature partial oxidation is an effective method for modifying reed straw, increasing methylene blue adsorption and removal efficiency, with a high yield, offering a new sustainable environmental management technology. A linear correlation exists between oxygen content and methylene blue adsorption at different modification temperatures, but under high temperature conditions, pore blockage and competition with metallic cations need to be considered.

Summary: By utilizing enantiopure building blocks, optically active cyclic dimers, trimers, and tetramers were prepared, showing clear Cotton effects and corresponding CPL signs. While the cyclic dimer did not emit CPL, the cyclic trimer and tetramer exhibited intense CPL emissions with a relatively high dissymmetry factor. Their optical and chiroptical properties were reproduced by time-dependent density functional theory calculations.

Summary: This study developed an innovative metal powder fabrication process called surface modification and reinforcement transplantation (SMART), which efficiently produces surface-modified feedstock powders for additive manufacturing of new alloys and composites. The working principles of the SMART process were established, and practical applications were considered by fabricating specialized feedstocks such as carbon nanotube-coated, Mo alloyed, and TiC particle-reinforced powders. The performance of the SMART powder was validated through the directed energy deposition process, and it was compared with existing processes to confirm its advantages.

Summary: In this study, NaF was introduced into a NaCl-LiCl-KCl molten salt to reduce the thickness of chromium carbide coating on diamond particles. The results showed that a continuous Cr7C3 coating of about 160 nm in thickness formed when NaF was mixed with the molten salt at 650 ℃. Lower temperatures (< 650 ℃) did not contribute to a continuous coating. As the temperature rose, the coating thickness gradually increased.

Summary: Natural diamonds were investigated using advanced chemical and structural analytical tools to comprehensively characterize their optically blind and optically active nitrogen impurity centers. The study established compositional relationships between X-ray photoelectron spectroscopy and Fourier-transform infrared vibrational spectroscopy signals of nitrogen impurity defects, and correlated depth-dependent spatial distributions of photoluminescence-active nitrogen defects with the carbon lattice signals. The study also revealed connections between local structural defects and stress-sensitive impurity distributions in bulk diamonds. These findings demonstrate the instrumental opportunities for in situ studies of diamond micro-features.

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: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

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: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

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.
