Available in PDF, EPUB and Kindle. Book excerpt: Tissue damage, loosening of implants, and the infection of the body are some of the most common complications that arise following surgical procedures. In dental and orthopedic medical implants infections are largely caused by the adhesion and growth of bacteria on the implant surface. Additionally, anatomical differences between the surrounding tissue/bone and the implant material can cause further complications. The usage of biomaterial-based implant coatings has been fundamental to the application of medical implants/devices and have improved mechanical properties. Successful implants must have favorable mechanical properties/wear resistance, provide strong biocompatibility/bioactivity, and display antibacterial properties. To date, bioactive coatings have generally been deposited using thermal spray methods such as plasma spray; however, this method of deposition has led to the melting and degradation of novel bioactive properties of hydroxyapatite (HA) as well as poor coating adhesion. This study discusses a novel approach of depositing biocompatible, bioactive, and antibacterial coatings well below their melting point using the cold spray process. The cold spray process was used to deposit composite powders with 70 wt% titanium (Ti), 20 wt% hydroxyapatite (HA), and 10 wt% chitosan (CS) onto aluminum 6061 (Al6061) substrates. The effect of process parameters was examined and the goal was to achieve antibacterial well-bonded coatings. The biofunctionality and corrosion resistance was investigated by a bacterial cellular assay and corrosion testing in the simulated body fluid (SBF) Hank's Balanced Salt Solution (HBSS). These tests compared the bacterial and corrosion resistance of composite coatings with commonly used implant substrate materials. The preliminary results indicate the phase composition of the Ti and HA remained the same before and after coating deposition. However, it is inconclusive whether CS particles remained in the same phase following deposition. Porous Ti/HA/CS coatings were obtained with more than double the porosity of Ti/HA coatings. Microstructural characterization and phase analysis of feedstock powders and as-deposited coatings was carried out using Field Emission Scanning Electron Microscope/Energy-Dispersive X-ray Spectroscopy (FESEM/EDS) and X-ray Powder Diffraction (XRD). The addition of the CS in the coating offered no improved antibacterial properties when compared to plain Al6061, 316 stainless steel (SS316), and titanium-6 aluminum-4 vanadium (Ti-6Al-4V) substrate samples. The reason for this lack of protection is still being investigated and could be attributed to a change in phase during the application or an insignificant amount of CS depositing.

Photoenergy materials are expected to be a next generation class of materials to provide secure, safe, sustainable and affordable energy. Photoenergy devices are known to convert the sunlight into electricity. These types of devices are simple in design with a major advantage as they are stand-alone systems able to provide megawatts of power. They have been applied as a power source for solar home systems, remote buildings, water pumping, megawatt scale power plants, satellites, communications, and space vehicles. With such a list of enormous applications, the demand for photoenergy devices is growing every year. On the other hand, thin films coating, which can be defined as the barriers of surface science, the fields of materials science and applied physics are progressing as a unified discipline of scientific industry. A thin film can be termed as a very fine, or thin layer of material coated on a particular surface, that can be in the range of a nanometer in thickness to several micrometers in size. Thin films are applied in numerous areas ranging from protection purposes to electronic semiconductor devices. The 16 chapters in this volume, all written by subject matter experts, demonstrate the claim that both photoenergy and thin film materials have the potential to be the future of industry.
