The development of these materials in bioscience and biomaterials is also significant. Graphene quantum dots are of interest due to their unique features in in-vivo imaging, develop drug delivery materials and improving the performance of dental implants. In the present research, some of the latest achievements in this field have been collected as a mini review. Graphene quantum dots can be used in drug delivery applications, development of in vivo imaging and similar cases. At the end of each section, suggestions are provided for researchers and more developing of Graphene quantum dots. Notably, this article only examines the latest achievements in the field of Graphene quantum dots and its results do not confirm or deny the use of this material in bioscience and biomaterials.

Characterization and Optimization of Cu-Al2O3 Nanocomposites Synthesized via High Energy Planetary Milling: A Morphological and Structural Study

Journal of Composites Science

This study examines the synthesis and characterization of a copper–alumina nanocomposite powder. ... more This study examines the synthesis and characterization of a copper–alumina nanocomposite powder. Mechanical milling is employed to synthesize the powder, and a holistic analysis is conducted to evaluate its morphological and structural properties. TEM analysis reveals the presence of alumina particles within the copper matrix, indicating the formation of both coarse and fine particles at different stages of synthesis. XRD analysis demonstrates a reduction in copper’s crystallite size with increasing milling time, attributed to defects generated within the crystal lattice during milling. Additionally, statistical analysis is utilized to determine the significance of different factors influencing the synthesis process. ANOVA analysis reveals that milling time has a significant impact on the particle size of the nanocomposite powder, while temperature and their interaction do not exhibit significant effects. Optimization techniques are utilized to identify solutions that meet the speci...

Regarding their excellent mechanical, physical and biological performance, new titanium alloys with non-toxic elements and long-term performance in the human body are described today. The main compositions of Ti-based alloys and properties comparable to existing classical alloys (C.P. TI, Ti-6Al-4V, Co-Cr-Mo, etc.) are used for medical applications. The addition of non-toxic elements such as Mo, Cu, Si, Zr and Mn also provides benefits, such as reducing the modulus of elasticity, increasing corrosion resistance and improving biocompatibility. In the present study, when choosing Ti-9Mo alloy, aluminum and copper (Cu) elements were added to it. These two alloys were chosen because one element is considered a favorable element for the body (copper) and the other element is harmful to the body (al...

In this study, the effect of heat treatment of hardening and annealing on the microstructure and mechanical properties of super-strength steel was investigated. For this purpose, hardening is done at 960 degrees Celsius and Quinch in three different environments of water, oil and air. The results of microstructural study indicate the formation of martensite with denser blades in water environment than budget oil. However, in air, the structure of ferrite-perlite and similar to base metal with low hardness is reported. Increasing the hardness of the base metal from 28 HRC to 38 and 61 HRC was made after heat treatment in both oil and water environments, respectively. Annealing was performed for one hour at 250 and 350 ° C on a sample that had a hardness of 58 and 52 HRC in water, respectively. Due to the lower than 55 HRC, it is not suitable for the performance of these steels and reduces the life of the tool, due to the conditions under which it is heated, including quenching in water and then annealing at 250 ° C for a period of time.
