Summary: The study found that CoFe2O4 and CoFe2O4-Chit particles are suitable for treating dye-contaminated wastewater, with CoFe2O4 having a higher adsorption capacity than CoFe2O4-Chit. In single-component solutions, the adsorption of CR/MO followed pseudo-first-order and pseudo-second-order kinetics models, while in binary solutions, the adsorption on CoFe2O4 better followed the pseudo-second-order kinetics model.

Summary: A new water stable MgO-PVP composite was prepared by hydrothermal method, showing higher surface area and adsorption capacity than plain MgO. The adsorption mechanism involved electrostatic force and ion exchange, with kinetic mainly controlled by film diffusion. Langmuir and DR isotherms were well fitted with experimental results, and dye removal capacity decreased with increasing initial pH value. The negative ΔG values indicated a spontaneous adsorption process.

Summary: Numerous water-treatment materials, including adsorbents, have been developed in recent years. The catalytic reduction behavior of carboxylated alginic acid derivatives against harmful organic dyes has been investigated. Metal complexes, including Sn-CAA, Fe-CAA, Ni-CAA, and Zr-CAA, were formed through coordination bonds between carboxylated alginic acid and selected metal ions. These complexes showed enhanced catalytic reduction against Methyl Orange and Congo Red, with Sn-CAA demonstrating the best catalytic reduction. The reduction time for Sn-CAA was 5 and 7 minutes for CR and MO, respectively.

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.
