Performance Analysis of TiO₂ Nanofluids in CNC Turning of Aluminium Alloy (AL319) Using the MQL Technique | Chapter 8 | Engineering Research: Perspectives on Recent Advances Vol. 4

Aluminium alloy AL319, known for its superior mechanical properties such as hardness and weldability, is widely used in industries like aerospace, automotive, and engineering. This study evaluates the performance of TiO₂ nanofluid in CNC turning operations on AL319 using the Minimum Quantity Lubrication (MQL) technique. Experiments were conducted with spindle speeds of 1000–1800 rpm, feed rates of 0.10–0.20 mm/rev, and MQL pressure of 0.5 MPa, using TiO₂ nanofluid concentrations of 0.5%, 1.0%, and 1.5% prepared via the one-step method. The cutting performance, assessed in terms of surface roughness, cutting temperature, and tool wear, was analyzed using Response Surface Methodology (RSM) and ANOVA. Results show that TiO₂ nanofluid with a 1.5% concentration achieved the lowest cutting temperature (28°C) and best surface roughness (0.863 μm Ra), outperforming dry, wet, and conventional MQL machining. The study concludes that TiO₂ nanofluids significantly enhance machining performance and, with their high thermal conductivity, are a promising solution for future heat transfer and machining applications.

Modern Techniques to Study Biokinetics of Nanoobjects in Living Organisms | Chapter 8 | Research Highlights in Science and Technology Vol. 1

 Strictly, Nanosafety is a field of Biomedicine. However, the plurality of the techniques grown and used for research in Nanosafety is interdisciplinary. Investigation of biokinetics of nanoobjects is an main arm of Nanosafety, which admits to estimate the toxicological load in the tissues of an unprotected organism and anticipate healing effect of the medicine. The present episode reviews various new methods to study the biokinetics of nanoobjects in living organisms. Common patterns of the biokinetics of exogenic wealth in a living organism and the big standard of a toxicological experiment are presented. A ample and inclusive presentation of Atomic Emission Spectrometry; Mass Spectrometry; X-ray Fluorescence Spectroscopy and Nuclear Physical Techniques to a degree Neutron Activation Analysis, Radiotracer Technique, In situ Neutron Activation Analysis; Microscopy and the article of their application or in general area of research are given. General mechanics approvals for the experiment planning are planned. The hypothetical approach to study nanoobject biokinetics based on the PBPK-displaying is thought-out. Examples of original studies on the biokinetics of TiO2 and Ag nanoparticles implemented accompanying the use of the deliberate techniques are bestowed. Authors attempted to share their own occurrence of research engaged of Nanosafety.

Advanced Methods for the Development of Highly Adhesive and Bioactive Nano Titania Coatings on Metal Substrates for Orthopedic and Dental Applications| Chapter 1 | Current Topics on Chemistry and Biochemistry Vol. 5

 Due to their superior physicochemical abilities to promote bone regeneration and cell proliferation, materials based on titanium dioxide (TiO2) have demonstrated significant potential for use in implants. This metal oxide has been the subject of the most research due to its excellent performance in a wide range of applications, chemical stability, and affordability. The purpose of this study is to evaluate TiO2's current application in dental and orthopedic implants. Researchers have studied a range of TiO2 coating deposition methods to strengthen the adherence and long-term reliability of metal implants. In this article, the various methods for depositing TiO2 on metal surfaces are carefully reviewed. The methods covered include electrophoretic deposition (EPD), electrochemical deposition (ECD), and biomimetic deposition, as well as anodization, the sol-gel method, plasma spray coating, cold spray coating, high velocity oxy-fuel spraying, and high velocity suspension flame spraying.

Fabrication of Titanium Dioxide Nanotubes with Reduced Bandgaps by Varying Electrolytic Concentrations: A Recent Study | Chapter 13 | Research Aspects in Chemical and Materials Sciences Vol. 1

 This study's main objective is to create titanium dioxide nanotubes with smaller bandgaps for hydrogen generation. Nanoscaled materials have many distinct properties than bulk materials, which has led to important scientific and technological achievements. Titanium dioxide nanotubes have a lot of promise due to their functional properties, such as a high surface-to-volume ratio. TiO2 nanotubes are produced via electrochemical anodization at a constant DC voltage of 12V for 1 hour. The sample's electrolyte is 0.25 wt% potassium fluoride dissolved in 99 percent ethylene glycol with a molarity of 0.004M. The electrolyte for samples B, C, and D was made by dissolving 0.004M of ethylene glycol in various concentrations of copper nitrate (Cu(NO3) 2 3H2O) (0.002mM, 0.003M,0.004M). Scanning of Field Emissions The creation of titanium dioxide nanotubes was studied using microscopy and photoluminescence spectroscopy, and the results were presented.
