Title: **Innovations by Ali Abdel-Rahman Mohammad Othman: A Focus on Advanced Nanocomposites**
Introduction
Ali Abdel-Rahman Mohammad Othman is a prominent inventor based in Riyadh, Saudi Arabia. With a total of two patents to his name, he has made significant contributions to the field of materials science, particularly in the development of advanced nanocomposites with antimicrobial properties. His work showcases a blend of innovative research and practical applications, particularly in the medical sector.
Latest Patents
Othman's latest patents include the development of an antimicrobial polymer-graphene-silver nanocomposite. This innovative product is created using a copolymer of styrene and methylmethacrylate that incorporates reduced graphene oxide and silver nanoparticles. The preparation involves an in situ bulk polymerization method utilizing two distinct techniques. Initially, a mixture of graphene oxide, styrene, and methylmethacrylate monomers undergoes polymerization with a free radical initiator. Following the incorporation of silver nitrate, the resultant product is reduced through microwave irradiation in the presence of hydrazine hydrate, leading to the formation of the R-(GO-(PS-PMMA))/AgNPs nanocomposite. This nanocomposite is particularly significant for its potential use in medical devices and related implants due to its antimicrobial properties.
In addition, Othman has developed a novel composition and method for creating a nanocomposite containing graphene sheets. This dual approach employs slight modifications and uses microwave irradiation to enhance the nanocomposite's properties. The developed material is applicable in various industries, including medical devices, automotive, paint, and even denture production. Remarkably, the method shows an increase of 136% in hardness and 76% in elastic modulus with the addition of just 2.0 wt % of the RGO nanocomposite produced via microwave irradiation.
