nanoparticles. The Fourier Transform Infrared Spectroscopy (FTIR) studies confirm the presence of PO43-, CO32- and Mg2+, and OH- groups. The UV-VIS Spectroscopy measurements show the reduction in the band-gap upon the temperature. Transmission Electron Microscope (TEM) images ascertained that nano HAP/MgO at 2500C and 3000C composite shows flakes like morphology. 1. Introduction Among all calcium phosphate bioceramics, hydroxyapatite (HAP), Ca10(PO4)6(OH)2, is the most extensively used biocompatible

used as a support for nano TiO2. TiO2 supported on activated carbon (xTiO2–AC) catalysts, (x = 10, 20, 50, and 70 wt. %), were prepared through a mechano-mixing method. The photo-catalysts were characterized by Raman, XRD, FTIR, SBET, FE-SEM and optical technique. The adsorption and photo-activity of the prepared catalysts (xTiO2–AC) were evaluated using Methylene Blue dye (MB). The photo-catalytic degradation of MB was evaluated under UVC irradiation and visible light. The degradation percentage

Effect of TiO2 enriched fluxes on bead geometry, grain size and hardness in Submerged Arc weld metals Joydeep roy1, S. C. Saha2 and R. N.

(µXRF) techniques. Also it was controlled to be cultured into other cancer cells such as cervical cancer HeLa cells and lung cancer A549 cells. Effect of fNDs on DDP delivery and releases were investigated. By ICP-OES (inductively coupled plasma optical emission spectrometry), drug loading efficiency was estimated. For cytotoxicity and biocompatibility analysis, cell viability was assessed on cancer cells by MTT [3-(4, 5-dimethylthiazol-2-yl)-2,

The decision to apply for a master’s program at the esteemed, Case Western Reserve University comes from a great passion to pursue research and personally contribute to the field of Biomedical Engineering. With the field’s innovative approach to bridge the gap between engineering and medicine, it has given answers to many of the pressing problems of healthcare system; nevertheless there are many challenges yet to overcome. For someone who has an avid desire to enrich her knowledge on advances in

conjunctivitis can be quite dreadful as disastrous results might occur. If you have weak retina or high power, then infectious elements can make your eye condition more critical and this is the reason medical histories need to be judged properly. Slit-lamp microscope is generally used by the eye specialists so that eye examinations can be conducted with great care and higher accuracy. Internal eye condition can be perfected examined

The process of diagenesis encodes information regarding the physical and chemical processes operating in nature, which precedes the taphonomical journey of a bone into the lithosphere. When decoded, a fossil or an archaeological bone entails a series of natural processes of modification that perhaps decided the ‘destiny’ of a bone to transform into a fossil over the years of its residence into the sedimentary environment. Understanding these processes involved in the bone diagenesis is crucial to

Ezugwu and Wang (1997) presented a review on the main problems associated with titanium machining, including tool wear and the mechanism responsible for tool failure. They suggest that uncoated carbides (WC/Co) cutting tools are better than most coated cutting tools for machining a titanium alloy. The high chemical reactivity of titanium causes welding of work-piece material on the cutting tool during machining, leading to chipping and premature tool failure. The prominent failure modes in titanium
