“…Titanium dioxide (TiO 2 ) or titania is an n-type semiconductor that existed in three different phases: brookite, anatase, and rutile [1][2][3]. TiO 2 has gained wide attention due to chemical stability, chemical inertness, non-toxicity, biocompatibility and low cost [4][5].…”

In this research, TiO2 thin films were prepared using a simple sol-gel spin coating process. The films were characterized using Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive Ray (EDX), X-ray diffraction (XRD) and Ultraviolet–visible Spectrophotometer in order to investigate the influence of different annealing temperatures to the structural and optical properties of TiO2. The surface morphology images from FE-SEM display a uniform layer of nanoparticles with a sample of 500 °C possess the most uniform and the visible spherical grain of TiO2 nanoparticles. EDX spectra confirm the presence of Ti and O elements in the samples. The structural properties from the XRD pattern demonstrate that the films are crystalline at a temperature of 500 and 600 °C and the peak (101) intensity was increased as the annealing temperature increased. They exist in the anatase phase at the preferred plane orientation of (101). The calculated crystallite size for 500 and 600 °C samples is 19.22 and 28.37 nm, respectively. The films also possessed excellent absorption in the ultraviolet (UV) region with optical band gap energy ranging from 3.32 to 3.43 eV. These results can be fundamental for the fabrication of a UV sensing device.

This study reports on an enzymatic glucose sensor based on mesoporous TiO2 nanoparticles (MTNPs) synthesized by a simple solvothermal method. The unique structure of MTNPs with a fairly homogenous shape, porous, and high crystallinity is the consequence of the use of PVP yang during the synthesis process. PVP plays an important role in creating the uniform morphology and mesoporous structure of MTNPs-2. The success of glucose oxidase immobilization on the surface of MTNPs was proven by FTIR and UV–vis characterizations. The prepared GCE/MTNPs-2/GOx electrode successfully detects glucose molecules with good sensing performance with a sensitivity of 0.4098 μA mM−1 cm−2, a wide linear range of 0.1–1 mM, and a relatively low detection limit of 73 μM.

“…Structures constructed on such soils as pipelines are predicted to suffer severe damage due to this behavior [40]. Clay soil can cause corrosion in steel pipes due to the presence of sulfate-reducing bacteria [41] and this will then cause some reactions that will lead to microbial-induced corrosion.…”

This study integrated geographic information system (GIS) and remote sensing technology to identify areas around pipelines that are more susceptible to corrosion having the Kurdistan pipeline as a case study. Geospatial data are used to target factors such as rainfall, temperature, rivers, and minerals which increase the corrosion rate. Spatial data such as, the direction of slope, rainfall, proximity to rivers, and minerals, were collected and analyzed; maps were created for every individual factor to visualize their distribution. By overlaying these maps, regions that are at higher risk of corrosion were identified, which can be prioritized for further investigation or preventive measures. This paper’s findings are significant for oil and gas industries, including pipeline operators and designers as corrosion can lead to devastating consequences. The novelty of this study is to identify areas along the pipeline at higher risk of corrosion through the application of geospatial information systems and remote sensing. This methodology holds immense potential for industries looking to proactively prevent corrosion through the implementation of preventative maintenance, monitoring programs, and the application of protective coatings and inhibitors. The results of this research demonstrate that environmental data, GIS, and remote sensing can predict corrosion in oil pipelines, offering valuable insights for better managing corrosion risk.
