Role of Surfactants in Nanotechnology and Their Applications.

Template-mediated self-assembly synthesis has produced a diverse range of biomimetic materials with unique physicochemical properties. Here, we fabricated novel fluorescent three-dimensional (3-D) hydroxyapatite (HAP) nanorod-assembled microspheres using iron quantum cluster (FeQC) as a hybrid template, containing three organic components: hemoglobin chains, piperidine, and iron clusters.

In developing countries and resource-limited regions, where no power infrastructure or waste heat from industrial plants is available, photothermal-driven membrane distillation (PMD) has been recognized as an attractive and sustainable technology for freshwater generation. PMD enables easy water collection.

Hollow hydroxyapatite microspheres as devices for.

Hydroxyapatite (HA) ceramics produced synthetically or by processing biological substrates and is used widely and successfully for bone reconstruction. There are many natural sources for HA which include human bone, bovine bone 1,2 coral 3,4 chitosan 5,6 fish bone 7 and egg shell 8, and so.The dissertation identified and explored several opportunities for urban water systems to deliver demand-side benefits to help manage the electric grid.. Hydroxyapatite.Hydroxylapatite is a very important biomineral: Carbonated calcium-deficient hydroxylapatite is the main mineral of which dental enamel and dentin are composed. Up to 50% by volume and 70% by weight of human bone is a modified form of hydroxylapatite, known as bone mineral (Wikipedia).


In this dissertation, novel biomaterials are designed for bone biomaterials and bone tissue engineering applications. Novel biomaterials of hydroxyapatite with synthetic and natural polymers have been fabricated using a combination of processing routes. Initially, we investigated hydroxyapatite-polycaprolactone-polyacrylic acid composites and observed that minimal interfacial interactions.Over 600,000 bone-grafting operations are performed each year in the United States. The majority of the bone used for these surgeries comes from autografts that are limited in quantity or allografts with high failure rates. Current synthetic bone grafting materials have poor mechanical properties, handling characteristics, and bioactivity. The goal of this dissertation was to develop a.

Hydroxyapatite is a very interesting ceramic that has been explored recently for various biomedical applications ranging from bone pastes and cements to tissue scaffolds due to its biodegradability and biocompatibility. However, its ceramic behavior makes it hard to use due to its high brittleness.

Hydroxyapatite composites as a biomaterial for hard tissue regeneration During the last decade considerable attention has been directed toward the use of implants with bioactive fixation, where bioactive fixation is defined as interfacial bonding of an implant to tissue by means of formation of a biologically active hydroxyapatite layer on the implant surface.

Carbonate hydroxyapatite has been synthesized from prototype human synovial fluid and its surface characteristics on titanium have been evaluated. We have studied the effect of suspension composition on the morphological and surface characteristics and quality of the coatings and examined the influence of dopants (silicate ions and gelatin) on the properties of the coatings.
