    Invited presentations in conferences and advanced schools;

    Since 2006 I delivered more than 50 presentations in conferences. About 40 of them in International Conferences held outside my country, in six cases as "Invited" or "Keynote" lecturer (2008, 2010, 2013, 2014, two occasions during 2015, 2016, 2017, two occasions during 2018, 2020). Some of those meetings are among the most important conferences in my field of research (2010-Trilateral USA-Japan-Spain Meeting on Clays, 2014 Clay Mineral Society Workshop, and 2015 EUROCLAY15, European Conference in Clay Sciences, 16th International Clay Conference, Asian Conference in Clay Sciences ). I was also invited to deliver an M.Sc. Course in Environmental Remediation at the International Master in Clay Sciences Program (IMACS), supported by the International Association of Clay Minerals Research (AIPEA) during 2016. As a result of the success of the course I had been asked by IMACS to do it (as "Remote Learning") in 2017 and 2018.

    Organization of conferences and congresses:

    Since 2006 I participated in the organization of several international conferences: (a) Initiator and Organizer of the “Chemistry in Water Treatment and Purification Symposium”, held at the 243rd American Chemical Society National Meeting & Exposition, in San Diego, California, March, 2012; (b) Symposium Organizer of the "Water-Related Medical Geology Issues" held at MEDGEO 2013, 5th International Conference in Medical Geology, Arlington, VA Aug. 25-29, 2013, and (c), Initiator and convener of the symposium on "Environmental Applications of Modified and Natural Clays", held in the 16th International Clay Conference, Granada, Spain 2017. Symposium Organizer for the “Clays in the Environment”, 4th Asian Clay Meeting (online), Thailand, July 2020. In addition to that, member of the steering committee of several conferences in Israel, among them the Ann. Meeting Israel Society of Clay Research, Upper Galilee, October 2011, and 1st, 2nd, 3rd and 5th Annual National Water Conference in Tel Hai College (2012-2017).

    Recognized leadership in industrial innovation and environmental aspects:

    - (a) A technology I am its senior inventor, that uses modified activated carbon for the removal of heavy metals and oxyanions in industrial and potable is applied by ToxSorb Co., a water technology "Cleantech" company that works since 2008 (company websiteadditional details), with clients in Israel, Italy and USA (see above, patent #1).

    - (b) A technology I am its sole inventor, based on the development of specifically designed clay-polymer nanocomposites for the clarification of water is the basis of several patents (see above, patents #2,3,6), part of them already at National Phase in US, Europe and other places. The license for the use of the technology in wastewater and effluents (patents #2,3) was assigned to ICL Haifa, a global manufacturer of products primarily in three markets: agriculture, food and engineered materials, and one of the largest chemicals companies in Israel. Since 2015 they are responsible for the introduction of the product known as "NC" to the industrial and domestic wastewater treatment in Israel and around the world (additional information in this press release, and at the following advertising movies: 12). 

    -(c) Negotiations about the funding of a clean-tech startup company based on the photocatalytic degradation technology developed in patents #12 and 16 is taking place (September, 2017). A Channel 10 television report on the technology (in Hebrew) was broadcasted on October, 3rd, 2017.
