Research Interest

The Biomaterials and Corrosion Laboratory
In line with the demands of modern society, the multidisciplinary Biomaterials and Corrosion Laboratory is conducting strategic R&D on advanced materials ranging from biomaterials and nanomaterials, to materials for space applications, and alloy deposition. The Lab also provides materials selection, quality control and failure analysis services, serving and collaborating with industrial, medical and defense organizations. Among the labís internationally renowned achievements are:

  • The development of novel electrochemically-deposited hydroxyapatite (HAp) coatings for orthopedic and dental implants. Coatings prepared in the lab have demonstrated higher performance than the commercial plasma-sprayed coatings with respect to osseointegration and occurrence of cracking.
  • The magnetic isolation of bone, cartilage, metals, synthetic polymers, minerals and carbon nano-spheres and nano-rods from a variety of liquids, including synovial fluids, ethanol and bovine serum. The applications include diagnosis of osteoarthritis, determination of the efficacy of drug treatment, and for monitoring the wear of artificial joints (either in the design stage or during service in vivo). The lab is the only one outside the US to have this capability (by means of Bio-Ferrography). 
  • Electroplating and electroless plating of Re-based alloys. These projects are conducted in collaboration with Prof. Eliezer Gileadi from the TAU School of Chemistry, and are intended for aircraft, aerospace, nuclear, chemical, electrical, biomedical and other applications.
  • The development of hybrid nano-composites with unique mechanical and electrical properties and improved durability in space, for example, with higher resistance to space debris collisions and to attack by atomic oxygen. The project is conducted in collaboration with the Space Environment Group at Soreq NRC.
