Improvement of blood compatibility of silicone rubber by the addition of hydroxyapatite
- 3D CUSTOM-MADE IMPLANTS FOR THE RECONSTRUCTION OF CRANIOFACIAL BONE DEFECTS. EVALUATION AT SEVEN YEARS OF USE. Rotaru, H.; Stan, H.; Schumacher, R.; Baciut, G.; Chezan, H.; Kim, S. - G. // Annals of DAAAM & Proceedings;2010, p1551
Important functional and esthetical impairments appear due to bone defects of the craniofacial skeleton. The development of rapid-prototyping technologies offers the possibility of reconstructing some of the bone defects with custom-made craniofacial implants from alloplastic materials. Bone...
- Effect of filler surface morphology on the impact behaviour of hydroxyapatite reinforced high density polyethylene composites. Zhang, Y.; Tanner, K. // Journal of Materials Science: Materials in Medicine;Feb2008, Vol. 19 Issue 2, p761
Instrumented falling weight impact tests have been carried out to characterize the impact behaviour of hydroxyapatite reinforced high-density polyethylene composite (HA-HDPE) in order to use this biomaterial in skull implants. The effects of HA filler surface morphology and volume fraction on...
- Materials from Titaniumâ€”Cobalt Alloys for Hybrid Implants. A. Sytschev; S. Vadchenko; O. Kamynina; E. Balikhina; I. Plashchina; E. Krylova; A. Grigor’yan; A. Toporkova; A. Konovalov; I. Selezneva // Bulletin of Experimental Biology & Medicine;Jan2009, Vol. 147 Issue 1, p160
We proposed a new method to increase the biocompatibility of porous materials that were synthesized from titanium and cobalt allows by the method of self-propagating high-temperature synthesis. This method suggested the introduction of calcium hydroxyapatite into the reaction mixture....
- Studies on Poly(propylene fumarate-co-caprolactone diol) Thermoset Composites towards the Development of Biodegradable Bone Fixation Devices. Jayabalan, M. // International Journal of Biomaterials;2009, Vol. 2009, Special section p1
The effect of reinforcement in the cross-linked poly(propylene fumarate-co-caprolactone diol) thermoset composites based on Kevlar fibres and hydroxyapatite was studied. Cross-linked poly(propylene fumarate-co-caprolactone diol) was also studied without any reinforcement for comparison. The...
- BEHAVIOR OF BLOOD CELLS BEING IN CONTACT WITH HYDROXYAPATITE-COATED TITANIUM PLATE WITHIN AN HOUR. LEICE, Alevtina; DEKHTYAR, Yuri; BRITZINA, Natalya // Medical Physics in the Baltic States;Oct2010, p142
Changes of 15 parameters in blood samples being in contact with the bioimplant (titanium plate, coated by hydroxyapatite layer) and undergoing blood ageing for an hour were investigated. Five consecutive measurements were analyzed. Blood exposure to the bioimplant resulted in statistically...
- 'Smart coating' may lead to safer hip, knee and dental implants. Press, Robert; Rapp, Susan M.; Springer, Thomas M. // Orthopedics Today;Mar2010, Vol. 30 Issue 3, p54
The article discusses research on the safety of functionally graded hydroxyapatite (FGHA) coatings with silver and titanium substrates for hip, knee and dental implants, by X. Bai and colleagues, published in the 2010 issue of "Acta BioMaterialla."
- Extraction of dielectric and magnetic properties of carbonyl iron powder composites at high frequencies. Zivkovic, I.; Murk, A. // Journal of Applied Physics;Jun2012, Vol. 111 Issue 11, p114104
In this paper, we examine carbonyl iron composites in silicone rubber and epoxy matrices. Transmission measurements were performed at W (70 to 110 GHz) and Ka (26 to 40 GHz) bands and effective permittivity and permeability of composites with 10% volume fraction of carbonyl iron powder (CIP)...
- Glueless Stickers Make a Splash in the Bathroom. // Australasian Science;Nov/Dec2004, Vol. 25 Issue 10, p12
Focuses on the silicon rubber stickers developed by the Australian-based Epatch company. Ability of silicon rubber to stick to smooth surfaces; Capability of Epatch stickers to survive at wet bathroom environment.
- Interactions of silicone rubbers designed for electrical engineering applications with aqueous media. Boinovich, L. B.; Emel'yanenko, A. M.; Pashinin, A. S. // Protection of Metals & Physical Chemistry of Surfaces;Jan2009, Vol. 45 Issue 1, p89
Interactions of a number of electrical engineering silicone rubbers with water and aqueous salt, weakly acidic, and weakly basic solutions were studied by measuring contact angles. A mechanism for leakage currents along the surfaces of silicone insulators was proposed.
