“…The uniform, thin coating layer on the struts of the scaffolds could be attributed to the spin coating process used. During the process, the centrifugal force could help the precursor solution evenly distribute inside the scaffolds and prevent the precursor from clogging [ 36 , 37 ].…”

Porous Ti-6Al-4V scaffolds fabricated by means of selective laser melting (SLM), having controllable geometrical features and preferable mechanical properties, have been developed as a class of biomaterials that hold promising potential for bone repair. However, the inherent bio-inertness of the Ti-6Al-4V alloy as the matrix of the scaffolds results in a lack in the ability to stimulate bone ingrowth and regeneration. The aim of the present study was to develop a bioactive coating on the struts of SLM Ti-6Al-4V scaffolds in order to add the desired surface osteogenesis ability. Mesoporous bioactive glasses (MBGs) coating was applied on the strut surfaces of the SLM Ti-6Al-4V scaffolds through spin coating, followed by a heat treatment. It was found that the coating could maintain the characteristic mesoporous structure and chemical composition of MBG, and establish good interfacial adhesion to the Ti-6Al-4V substrate. The compressive strength and pore interconnectivity of the scaffolds were not affected by the coating. Moreover, the results obtained from in vitro cell culture experiments demonstrated that the attachment, proliferation, and differentiation of human bone marrow stromal cells (hBMSCs) on the MBG-coated Ti-6Al-4V scaffolds were improved as compared with those on the conventional bioactive glass (BG)-coated Ti-6Al-4V scaffolds and bare-metal Ti-6Al-4V scaffolds. Our results demonstrated that the MBG coating by using the spinning coating method could be an effective approach to achieving enhanced surface biofunctionalization for SLM Ti-6Al-4V scaffolds.

“…Several studies have attempted to synthesize GaN nanostructures using various growth techniques, including metal-organic chemical vapor deposition [20], reactive molecular beam epitaxy [21], thermal ammonization [22,23], physical vapor deposition [24,25], chemical vapor deposition (CVD) [26], sol-gel chemistry [27], electrochemical deposition [28], thermal vapor deposition [29], and pulsed laser deposition (PLD) [30]. These methods have a common drawback in high temperatures and costly chemicals, leading to a relatively low production yield.…”

The pulsed laser ablation approach was used to synthesize gallium nitride (GaN) nanoparticles (NPs) at six distinct ablation energies. The nanoparticle was deposited on a quartz substrate using the drop cast technique. Two peaks of h-GaN nanostructures are detected in the XRD pattern, at 2θ = 34.64 and 37.98, reflected from the (002) and (100) planes, respectively. The hexagonal crystal nature of GaN is indicated by the morphological features, which is shown in the XRD pattern. The greatest laser power, 2000 mJ, shows a modest emission peaking at 3.34 eV, according to photoluminescence (PL) spectra. At 1400 mJ, the highest emission peak was 3.83 eV. The pulsed laser is used in this study to create nanoparticles with various characteristics.

This study involves synthesizing gallium nitride (GaN) nanoparticles (NPs) under six different ablation energies using the pulsed laser ablation method. The nanoparticle was deposited using drop cast method on a quartz substrate. XRD pattern shows two peaks of h-GaN nanoparticles at 2θ = 34.64 and 37.98, reflected from (002) and (100) planes. The morphological properties indicate the hexagonal crystal nature of GaN that shows in the XRD pattern. Photoluminescence (PL) spectra show the highest laser power, 2000 mj has a minor emission peaked at 3.34 eV. The maximum emission peak 3.83 eV at 1400 mJ. The study depends on the pulsed laser to generate nanoparticles with different characteristics.
