AI Article Synopsis
- The study focuses on improving the mechanical and wear properties of magnesium alloys used in biomedical applications by incorporating titanium dioxide (TiO) nanofibers.
- The TiO nanofibers were created through electrospinning and mixed into the magnesium matrix using ball-milling, with varying amounts (0, 1, 3, 5, and 10 wt.%).
- Experimental results demonstrated that adding TiO nanofibers up to 5% significantly enhanced both the mechanical strength and wear resistance of the magnesium composites, supported by finite element modeling that matched experimental findings.
Article Abstract
Biomedical applications, such as artificial implants, are very significant for the disabled due to their usage in orthopedics. Nevertheless, available materials in such applications have insufficient mechanical and tribological properties. The current study investigated the mechanical and tribological properties of a biomedical metallic material, magnesium (Mg), after incorporating titanium dioxide nanofibers (TiO) with different loading fractions. The TiO nanofibers were synthesized using the electrospinning technique. The ball-milling technique was utilized to ensure the homogenous distribution of TiO nanofibers inside the Mg matrix. Then, samples of the mixed powder with different loading fractions of TiO nanofibers, 0, 1, 3, 5, and 10 wt.%, were fabricated using a high-frequency induction heat sintering technique. The physicomechanical and tribological properties of the produced Mg/TiO nanocomposites were evaluated experimentally. Results showed an enhancement in mechanical properties and wear resistance accompanied by an increase in the weight fraction of TiO nanofibers up to 5%. A finite element model was built to assess the load-carrying capacity of the Mg/TiO composite to estimate different contact stresses during the frictional process. The finite element results showed an agreement with the experimental results.

Photoelectrochemical sensors have been studied for glucose detection because of their ability to minimize background noise and unwanted reactions. Titanium dioxide (TiO), a highly efficient material in converting light into electricity, cannot utilize visible light. In this regard, we developed a nonenzymatic glucose sensor by using a simple one-step electrospinning technique to combine cupric oxide with TiO to create a heterojunction.

As a sustainable alternative technology to the cost- and energy-intensive Haber-Bosch method, electrochemical nitrogen (N) reduction offers direct conversion of N to NH under ambient conditions. Direct use of noble metals or non-noble metals as electrocatalytic materials results in unsatisfactory electrocatalytic properties because of their low electrical conductivity and stability. Herein, three-dimensional flexible carbon nanofiber (CNF/TiO@CoS) nanostructures were prepared on the surface of CNF by using electrospinning, a hydrothermal method, and in situ growth.

Water purification has always been a critical yet challenging issue. In this study, an organic-inorganic composite membrane was developed using 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized bacterial cellulose (BC) nanofibers and hydroxyapatite nanowires (HAPNW) with tunable wettability for advanced membrane separation applications. The resulting free-standing TEMPO-BC/HAPNW filter membrane exhibited strong mechanical strength, high flexibility, exceptional deformability, and a high pure water flux of up to 800 L·m·h due to its porous architecture and inherent hydrophilicity.

Fluorescence spectroscopy employed to compute the antibacterial potential of pure ZnO and Titania (TiO) loaded ZnO (TiO: 2%, 4%, 6%, and 8%) electrospun nanofibers. The study of electrospun nanofibers followed by their structural, morphological and antibacterial properties has been revealed through fluorescence spectroscopy. X-ray diffraction (XRD) analysis of nanofibers calcinated at 600 °C revealed the presence of polycrystalline wurtzite hexagonal crystallographic planes of ZnO with preferred orientation along (101) direction.

The development of skin-protective materials that prevent the adhesion of cnidarian nematocysts and enhance the mechanical strength of these materials is crucial for addressing the issue of jellyfish stings. This study aimed to construct superhydrophobic nanomaterials capable of creating a surface that inhibits nematocyst adhesion, therefore preventing jellyfish stings. We investigated wettability and nematocyst adhesion on four different surfaces: gelatin, polydimethylsiloxane (PDMS), dodecyl trichlorosilane (DTS)-modified SiO, and perfluorooctane triethoxysilane (PFOTS)-modified TiO.
