INTRODUCTION:

Over 52 Years professional experience with industry and academia in innovative research, teaching, consulting, entrepreneurship and management, in addition to 5 years of graduate studies.

SIGNIFICANCE OF DR. ATTIA’S RESEARCH:

Dr. Yosry Attia’s impactful research has been generally in response to major and urgent national and international issues, as well as to individual industrial requests.

A few examples of his wide ranging research are:

  • Mineral and Materials Processing: Advanced the boundaries of colloid and surface chemistry of various materials, including biomaterials and designed selective chemicals to make the recovery of many valuable resources possible.
  • Cancer Treatment and Prevention:
  1. Designed and developed selective drug delivery system to cancer tumors, which could potentially reduce chemotherapy drugs use and their harmful side effects by up to 280 times.
  2. Developed a possible cancer prevention product “Bilipidex” to reduce excess body fat, which promotes cancer, as well as other serious diseases.
  3. Designed and applied highly efficient aerogel adsorbents for the capture and removal of carcinogens from tobacco smoke; 80% removal when placed in cigarette filter, and 96% removal when mixed with cigarette tobacco.
  4. Invented, developed polyethylene aerogel fiber web textiles for making cancer safe undergarments.
  • Environmental: First to design and develop highly efficient aerogel adsorbents and catalysts for capture and removal of pollutants and carcinogens from air, water, and soil.
  • Electronics:
  1. First to develop micro thin polyethylene aerogel wafers for thermal insulation of computer electronics to enable the design of super computers. Also dielectric aerogel wafers for printed circuit boards.
  2. Invented aerogel materials for electronics protection in aerospace applications, such as auto-pilot aircrafts and drones to improve performance and precision.
  3. Developed aerogel wafers for W-band antenna.
  • Other Research Impacts:
  1. In April 2024, Research Gate notified Dr. Attia that the interest score in his research is higher than 85% of all the 25+ million worldwide research members.
  2. On October 11, 2024, Dr. Attia became an Honored Listee of the Marquis Who’s Who, 2024.

ACHIEVEMENTS AND CONTRIBUTIONS

  • First to develop and prepare selective polymeric flocculants and selective flocculation process for copper minerals and ores.
  • First to discover and later develop with a colleague, a nephelometric technique for determination of high molecular weight polymers.
  • Prepared and developed selective polymeric dispersants for pyrite removal from coal and non-sulfide minerals. A patent was awarded (with Prof. D.W. Fuerstenau).
  • Developed a novel selective flocculation process for cleaning ultrafine coal using specially developed hydrophobic polymers. A series of patents was issued to sponsor.
  • Designed a processing flowsheet for the recovery of gold and other precious metals from placer sand. A 10-ton/hr. mobile pilot plant was constructed and tested based on this flowsheet. A patent on the process was awarded (with T.L. Tewksbury).
  • Tailor-designed novel polymeric flocculants for selective flocculation of tin oxide minerals from ores and tailings.
  • Outlined scientific principles for reagent's selectivity towards various types of mineral solid surfaces.
  • Significant contributions towards the role of solution chemistry of minerals and surfactants on their surface chemical behaviors in water.
  • Among the first to use dissolved air flotation for minerals' separation. Directed the development of physical processes for upgrading a nickel laterite ore prior to chemical processing. A net savings of $16,000,000/year was estimated to result from the implementation of this processing scheme.
  • Pioneered the concept of reversible polymer adsorption in the flocculation and deflocculation of clay.
  • Probably the first to demonstrate polymer adsorption on minerals during selective flocculation, using electron microscopy techniques, to largely confirm and modify the mechanistic theory of flocculation.
  • Developed a processing scheme for the recovery of short asbestos fibers from tailings. A 90 percent recovery of clean fibers was achieved.
  • First to establish possible mechanisms for selective flocculation in biotechnology.
  • Among the first to recognize the potential use of aerogel materials in many applications besides thermal insulation, and developed many aerogel based materials and technologies for over fifty different industrial sectors.
