Summary: In this study, a micro-arc oxidation (MAO) process with calcium was introduced to improve the interfacial strength of Titanium with a bioceramic hydroxyapatite (HA) coating. The MAO coating comprised porous TiO2 with Ca or CaTiO3, and the HA coating on the MAO coating was confirmed to be plate-like Ca-deficient HA. The MAO coating containing Ca as a connecting interlayer showed promising results in improving the HA adhesion strength with an adhesive strength of 2.326 MPa.

Summary: Bone-like hydroxyapatite (HAp) was prepared from 1.5SBF with different pH values, resulting in micro-sized particles with higher Ca/P ratio and crystallinity at pH 7.4, and nano-sized particles at pH 8.0 and 8.4. A mixture of micro-sized and nano-sized particles was obtained at pH 7.7. Monitoring Ca2+ concentrations showed a drastic decrease at pH 7.4, slightly decreased at higher pH, and higher at pH 7.7. The cytotoxicity of the obtained precipitates to mesenchymal stem cells was lower than that of synthetic HAp.

Summary: In this study, antibacterial implants were developed by incorporating different amounts of multi-walled carbon nanotubes (MWCNTs) with hydroxyapatite-tantalum pentoxide (HA-Ta2O5) and applying them onto NiTi using electrophoretic deposition (EPD) method. The addition of MWCNTs increased the density of the HA-Ta2O5 coating and improved its adhesion strength to NiTi. Furthermore, the MWCNTs enhanced the antibacterial property and electrochemical behavior of the coating.

Summary: Graphene oxide (GO)/hydroxyapatite (HA) composite coatings were successfully prepared on titanium substrates using electrophoretic deposition technology. The coating's microstructure, phase composition, adhesion strength, hydrophilicity, corrosion resistance, bioactivity, antibacterial activity, and biocompatibility were evaluated. The adhesive strength of the coating increased by 76% when the GO content increased from 0 wt% to 12 wt%, and the corrosion rate reached its minimum at (1.493 x 10-3mm/a) with 8 wt% GO. Biomineralization experiments demonstrated the excellent bioactivity of the GO/HA composite coatings. The water contact angle of the composite coatings increased from 20.6 degrees (0 wt% GO) to 38.1 degrees (12 wt% GO). The antibacterial rate of the coating with 5 wt% GO was 96.7%, but decreased to 25% after thermal treatment. In-vitro L929 cell culture experiments confirmed the biocompatibility of the composite coatings with 5 wt% GO.

Summary: In this study, it was discovered that mixing 2-(2-hydroxyphenyl)-1H-benzimidazole (HPBI) molecules with zeolitic imidazolate framework-8 (ZIF-8) colloidal suspensions resulted in significantly enhanced fluorescence. Through various techniques, it was found that HPBI molecules adsorbed onto the surface of ZIF-8 particles coordinatively and electrostatically, forming a new type of fluorescence emitter. These emitters were distributed periodically on the outer surface of ZIF-8 particles, with fixed distances smaller than the excitation light wavelength, suggesting the possibility of triggering collective spontaneous emission.

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: 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.
