Summary: This study proposes a growth kinetics model for ZrO2 in atomic layer deposition (ALD) using a mixed alkylamidocyclopentadienyl zirconium precursor. The model is based on experimental data and evaluates film growth behavior using reactor-scale simulation. The study finds that the adsorption of Cp-Zr molecules is hindered by the bulkiness of remaining ligands on adsorbed species. The hindrance effect is significant at temperatures between 150°C and 250°C, but decreases with increasing temperature and disappears at 300°C. The research provides valuable insights for optimizing ALD deposition processes of high-k metal oxides.

Summary: Metal-organic frameworks (MOFs) are explored as a precursor for producing porous metal oxide-supported nitrogen-doped carbon nanomaterials. In this study, nanocrystalline titanium dioxide-supported nitrogen-doped carbon nanostructures (TiO2@NC) were fabricated from a titanium MOF and showed efficient removal of tetracycline (TC) in aqueous solutions. The TiO2@NC nanospheres exhibited high adsorption capacity, broad pH range suitability, and excellent stability. The adsorption process was influenced by nitrogen sites, surface area, and porous sphere morphology.

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: This study investigates the effects of adding Zr4+ and Ni2+ on the performance of hematite photoanode thin films in the photoelectrochemical hydrogen production process. Chemical mapping reveals the preferential segregation of Zr4+ at the interface and grain boundaries, while Ni2+ is mainly present on the hematite-free surfaces. The introduction of Zr4+ improves the back contact, facilitating electron collection and flow through the external circuit. Structural analysis also shows lattice distortions and strain field accumulation at the interface region.

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.
