Summary: The study evaluated the applicability of B2O3 in the TiO2 slag process by investigating its rheological properties and molten oxide structure in the FeO-TiO2-B2O3 system. The addition of B2O3 was found to enhance energy efficiency and operational conditions, while reducing the liquidus temperature and increasing viscosity. Analysis of the molten oxide structure revealed the presence of borate and titanate structures, which significantly influenced viscosity.

Summary: A core-shell-structured nano-lubricating additive was synthesized using the DBDP-assisted ball grinding technique. The particle size of nano-TiO2 was refined, resulting in increased lattice distortion rate and oil affinity enhancement. The introduction of a CTAB-compatible group onto the surface of nano-TiO2 particles produced a modified layer with superior thermal stability. The electrostatic forces played a crucial role in the organic modification of the TiO2 surface. The addition of TiO2@CTAB composite oil exhibited improved lubrication performance under boundary lubrication conditions, reducing friction and wear.

Summary: In this work, a multiscale and comprehensive study was conducted to investigate the heterogeneous interaction between H2O2 and TiO2 particles. The adsorption of H2O2 and H2O on the TiO2 surface was found to be primarily determined by the weaker interaction between Ti and O atoms. The adsorption energy was dominated by electrostatic effect, and the adsorption energy of TiO2-H2O complexes was lower than that of TiO2-H2O2 ones. H2O2 and H2O interacted with TiO2 particles through molecular adsorption and dissociation, resulting in surface modification and Ti-OH formation. The uptake of H2O2 on TiO2 surface was suppressed with increasing humidity, possibly due to competition for surface sites with H2O.

Summary: Wettability is a key factor that affects the performance of metal surfaces. This study used molecular dynamics simulation to investigate the wetting behavior of liquid droplets on metal surfaces with different surface energies and morphologies. The results show a negative correlation between the solid-liquid interaction factor and the contact angle, and different surface morphologies have a significant impact on wettability.

Summary: It is found that the BaO-CaO-Al2O3-TiO2-Li2O slag system, which has low reactivity, can be used for the continuous casting of high-titanium steel. MD simulations show that Al2O3 exhibits amphoteric behavior when TiO2 content is less than 3 wt%, while TiO2 exhibits amphoteric behavior when TiO2 content is more than 3 wt%. The NBO/T ratio increases continuously in the low TiO2 system ranging from 1 to 6 wt%, but first increases and then decreases in the high TiO2 system ranging from 7 to 12 wt%.

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.

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.
