Summary: In this study, ZnO nanostructured thin films-based UV detectors were developed using a cost-effective sol-gel spin coating method. It was found that the UV detection performance and optical properties of the films can be significantly altered by adjusting the grain size and rpm. The prepared films also exhibit high optical transmittance in the visible region of the solar spectrum, providing a promising approach for improving the performance of ZnO nanostructures-based optoelectronic devices.

Summary: Single, double, and triple-coated undoped ZnO thin films were prepared using sol-gel spin coating technique on quartz substrate. The films had hexagonal wurtzite structures and wrinkles-like morphology. Optical band-gap was almost identical for all three films. Room temperature Photoluminescence (PL) spectra showed decreased visible PL intensity with increasing excitation wavelengths, followed by the emergence of a sharp NBE-like UV peak.

Summary: ZnO films with varying thicknesses were deposited for UV photodetection. The photoconductivity parameters of the photodetector were studied for UV radiation with a 365 nm wavelength. The deposited ZnO films showed poly-crystallinity with rough surfaces and oxygen-related defects, which enhanced UV photosensitivity. The photoconducting mechanism was studied using statistical interpretation of defects observed from photoluminescence spectra deconvolution. The 221 nm thick ZnO film exhibited improved photoconducting parameters due to increased defect density.

Summary: In this work, the nanomechanical behaviors and optical properties of nanohybrid thin films coated on polycarbonate substrates were investigated. The sol-gel process was used with TEOS, GPTMS, and aluminum tri sec-butoxide as main precursors. The results showed that upward speed had a significant effect on nanomechanical properties, while optical properties remained constant. The prepared thin films had a lower refractive index than the PC substrate, resulting in increased transmittance. Furthermore, the nanohybrid thin films improved the hardness and elastic modulus of the PC substrate, while reducing the friction coefficient and increasing pencil hardness.

Summary: A simple aqueous sol-gel procedure was used to produce hard transparent organic-inorganic coatings on polycarbonate (PC). The coatings were prepared by mixing Si and Al aqueous alkoxides and applied on plasma-treated PC. The coatings showed higher transmittance and good adhesion onto the substrates. The pencil hardness of the PC substrate improved significantly with just a single layer coating.

Summary: Yb-doped ZnO thin films were fabricated using spin coating method at low temperature. The films maintained the hexagonal wurtzite structure even at high doping levels. Increases in Yb content led to slight decreases in lattice parameters and crystallite size, along with denser surface microstructures. Optical properties showed high transmittance, increased bandgap, and decreased refractive index and extinction coefficient with higher Yb doping levels. The photoluminescence results indicated strong UV emission, making these films suitable for optoelectronic applications.

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.

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.
