Magnetic nanoparticles (Nanomagnets) can be classified to soft or hard magnetic materials. Soft magnetic materials such as Fe, Co, Ni or their alloys with Ru and Pt can be used for medical applications. One of the advantage of such particles that it can emit energy in a form of heat under applied external magnetic field and once the magnetic field is removed, no remnance magnetization will remain. This unique property can be used for cancer treatment which is called magnetic hyperthermia.
The other type of the magnetic nanoparticles is hard magnetic materials. CoxC, MnGa, and CoFeC nanoparticles are good examples of hard magnets which have the property of storing magnetic energy even after removing the magnetic field. Such property is commonly used for fabrication of permanent magnets. The main advantage of such particles is due to the higher magnetic anisotropy which can act as good candidate for new generation of magnetic data storage.
When aiming at realizing the promises of applied nanomagnetism, however, many researches and challenges were required to be done in the last few years from the laboratory scale to fabrication scale. Therefore, the talk focusses on the synthesis of different types of magnetic nanoparticles and their potential for both medical and industrial applications.
Dr. El-Gendy has been working in the field of magnetic nanoparticles for 15 years. His research expertise includes synthesis, characterization and applications of functionalized magnetic nanoparticles. He received his Ph.D. degree in physics from Heidelberg University, Germany 2011. From 2012-2017, He worked in various research positions on both levels academic and industry, as a postdoctoral researcher and senior scientist at Virginia Commonwealth University (VCU), Virginia (2012-2013, 2015-2017), Nanofoundary LLC., and University of Delaware (UD), Delaware (2013-2015), USA. In fall 2017, he joined department of physics at UTEP as tenure track assistant professor to establish his group in nanomagnetics and biomaterials. His work interests focus on synthesis and optimization of soft and hard magnetic nanomaterials using chemical and physical methods to be used for various types of applications such as hyperthermia treatment for cancer, drug delivery, contrast agent for MRI, rare‐earth free permanent magnets, data storage, and magneto‐caloric for refrigeration technology. He has published more than 40 (11 in 2017) high impact scientific papers in peer-review journals and book chapters. He is a reviewer for numerous high ranked scientific journals. He is editing a book of magnetic nanostructured materials published by ELSEVIER in 2018-2019. During 2015-2016, scientific newspapers highlighted his work on novel rare-earth free permanent magnet material. In addition, he holds one US-patent and five US-provisional patents. In 2017, he has been awarded a highly competitive international young scientist award by national science foundation in China (NSFC). Based on his career achievements, his biography was approved to be listed in Marques who’s who in America in 2018.
