Summary: Ba-doped TiO2 thin films were fabricated using the sol-gel dip-coated method. X-ray diffraction confirmed the formation of the anatase phase. With the increase of Ba doping, the size of the crystallite decreased. The bandgap of pure TiO2 and Ba-doped TiO2 thin films was in the range of 3.15-2.94 eV, which is beneficial for enhancing solar cell efficiency and water treatment. Ba-doped TiO2 thin films exhibited low dielectric constant suitable for high-frequency devices and showed ferromagnetism. The antibacterial activity of Ba-doped TiO2 was higher than that of pure TiO2, making it suitable for application in nanomedicine.

Summary: Ag-TiO2-Fe composite thin films with different Ag contents were deposited onto a glass substrate by thermal evaporation. The films were characterized to investigate the relationship between their structural, morphological, optical, and luminescent properties with their antibacterial activities. The results showed the formation of the anatase phase with increasing silver content in the films, and the presence of metallic silver. The films exhibited a redshift in the optical absorption edge and a decrease in the energy bandgap compared to pure TiO2. The antibacterial activity of the films was found to be influenced by the presence of silver, with a synergistic effect observed under UV light.

Summary: A novel approach to alter the surface of nanocrystalline anatase with pristine titania by chemisorption of a stable water-soluble titanium complex is studied. On-air calcination removes organic residues, converting chemisorbed complexes into oxide phase increments while retaining crystallinity and specific surface with simultaneous withdrawal of surface hydroxyl groups.

Summary: P-doped nc-SiOxCy:H films were grown at moderate conditions, showing the systematic formation of Si-C and Si-O-C bonds with the increase in CH4 flow rate. XPS studies confirmed the presence of Si-O-C bonds and P atoms as dopants in the network, while the optical band gap was enhanced by the addition of stronger Si-C bonds and quantum confinement effect from reduced nanocrystal size. The optimal n-type nc-SiOxCy:H film exhibited promising properties for use in all-Si tandem solar cells.

Summary: Core/shell nanoparticles composed of SnO2 core and TiO2 shell show practical interest in dye-sensitized water splitting. Electroabsorption studies indicate that the shell can screen an electric field from a surface anchored dye. The field strength is significantly reduced when using SnO2/TiO2 core/shell materials compared to TiO2 alone.

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: This paper presents a detailed study on the hydrogen sensing capabilities of highly nanoporous black gold films. The films exhibit fast response and recovery times at low temperatures. Different levels of nanoporosity were prepared and tested to investigate the sensing properties, and it was found that nanoporous black gold is suitable for hydrogen sensing. The sensitivity of the film depends on its nanoporosity.

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.
