On the polymer-based nanocomposites for electrical
This technology combines the uniform mixing effect of ultrasonic atomization precipitation at high concentration with the rapid and unif 2009-11-25 · Hydroxyapatite (HA) nano powders (20–60 nm) were synthesized using a sol-gel route with calcium nitrate and phosphoric acid as calcium and phosphorus precursors, respectively. Double distilled water was used as a diluting media for HA sol preparation and ammonia was used to adjust the pH. After aging, the HA gel was dried at 65°C and calcined to different temperatures ranging from 200–800 In this study, wet-chemical process was performed to prepare nano-size hydroxyapatite (HA) powders (≈10 nm) by varying concentration (low, medium and high) of the starting solutions in order to increase the amount of as-dried HA powders with different process conditions. Particle sizes and density were analyzed and differential thermal analysiswas used to determine the glass transition (T g Company A and C (material 1): Hydroxyapatite as the main component; Potassium chloride (KCl) as preservative and water as excipient.
The OH − ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system. Pure hydroxyapatite powder is white. Hydroxyapatite Nanoparticles: Nanoclay as drug vehicle Nanoclay as drug vehicle for controlled release of drug is one of the born age area in medical application, nanoclay have great potential as compared to polymer and carbon nano tubes for drug delivery applications.

Nano-Medical Hydroxyapatite is showing up in toothpastes as an alternative to fluoride. It is a gold standard ingredient for oral health products in Japan known to combat tooth decay by remineralizing and repairing teeth.
In addition, the nano-HAP powder was further calcined to get HAP microparticles. We used poly(D,L-lactic acid) with a molecular weight of 100,000 which was purchased from Jinan Daigang Biomaterial Co., Ltd (China). PLA/nano-HAP microspheres were prepared by a solid-in-oil-in
Hydroxyapatite Powder: Clays are hydrous alumino-silicates broadly defined as those minerals that make up the colloid fraction of soils, sediments, rocks, and water and may be composed of mixtures of fine grained clay minerals and clay-sized crystals of other minerals such as quartz, carbonate, and metal oxides. Nanstreams produces nano-hydroxyapatite (40nms) in powder, dispersion or paste forms for use in toothpaste, dental cements, and dental resins
In this research, hydroxyapatite (HA) nano-size powder was synthesized using wet chemical precipitation technique under atmospheric pressure where calcium hydroxide (Ca(OH) 2) and ortho-phosphoric acid (H 3 PO 4) were used as precursors.
