The aim of this study is to investigate the antioxidant activity and dose improvement factor (DEF) of CeO. The antioxidant activity of CeO NPs was analyzed by the reduction of 1,1-diphenyl-2-picrylhydrazil (DPPH) stable free radical using UV-vis spectroscopy. The dose improvement factor (DEF) of CeO NPs was investigated using X-rays with an energy of 6 MV.
CeO NPs also show the ability to absorb X-ray radiation with DEF value < 1 and reduce the E . Antioxidant activities CeO2 nanoparticles Dose enhancement factors Fluorite structure Mixed valence state Precipitation methods UV-vis spectroscopy X-ray diffractometers.

In 2002 he joined ANSTO as an instrument scientist on the AUSANS instrument at the HIFAR reactor and then in 2005 assumed the role of Operations Manager for the Bragg Institute at ANSTO before assuming his current role in 2016 as the Leader of ACNS recorded.
She then returned to Germany and completed her doctorate at the Technical University (TU), Berlin, Germany. Since 2012, Evvy Kartini has been appointed as one of the referee members of the National Accreditation Journal of the Indonesian Institute of Science. He joined the Peruvian Institute of Nuclear Energy, where he was awarded an International Atomic Energy Agency (IAEA) fellowship, which brought him to the US to receive training in neutron scattering at the National Bureau of Standards (now the National Institute of Standards and Technology). in Gaithersburg, Maryland, and at the University of Maryland-College Park.
He is currently a Distinguished Research Fellow in ORNL's Division of Quantum Condensed Matter and leader of the triple axis spectroscopy group at the High Flux Isotope Reactor - one of the US Department of Energy's major science user facilities -'s for neutrons. Fernandez-Baca's expertise is in the study of magnetic ordering and spin dynamics of complex oxides and related alloys using neutron scattering techniques. Fernandez-Baca is a member of the American Physical Society and the Neutron Scattering Society of America.
He is currently a Professor in the School of Materials Science and Engineering and also Senior Executive Director in the Office of the President, Nanyang Technological University (NTU) and Visiting Professor at the Shanghai Institute of Ceramics, China. Chowdari has served as President of International Union of Materials Research Societies (IUMRS) and Asian Society for Solid State Ionics, and Chairman of the 15th Asian Physics Olympiad (AphO 2014). She was Head of the New and Renewable Technology Division and Director for the Materials Technology Center in 2014-2015 and has been active since 2013 as one of the Board.
Astrid Schneidewind obtained her PhD in physics with the thesis Analysis of The Magnetic Structures od Rare-Earth-CU Compounds Using Magnetic X-ray and Neutron Di raction. He was project manager for the Neutron Beam Instrument Project, responsible for building eight world-leading neutron beam instruments at OPAL at a cost of DKK 35 million. USD in mid-2007. More recently, as Technical Director of the Bragg Institute, he oversaw the design and construction of OPAL's second suite of neutron beam instruments and expansion of the Cold Neutron Transport System.
KEYNOTE SPEAKER
He also has extensive experience in applying these methods to the study of. Then in 2009-2011 as Chairman of the School of Applied Physics and from 2011 to 2013 became Deputy Dean of the Faculty of Natural Sciences and Technology. She currently lives in Sweden and consults with a number of companies in the USA, Europe and Australia in the R & D and commercialization of radioisotopes and radiopharmaceuticals.
She has over 25 years of experience in the development of radioisotopes using accelerators (up to 200 MeV protons) and reactors. As production manager of the Brookhaven Linac Isotope Producer, USA, she developed new targets and methods for the production of radioisotopes using high-energy protons and led the production team to the highest yield (in a 30-year operation) and most reliable production of radioisotopes. cGMP Sr-82 used for cardiac imaging. He is also a member of various committees of the International Organizations for Standards in the field of radon and radiation measurements.

The presence of the filler can reduce the production cost and under certain conditions can also improve the mechanical properties.
This work aimed to study the influence of CaCO filler in tensile properties of polypropylene. The results showed that the mixture of 5% (w/w) CaCO achieved the highest tensile strain and elastic modulus, but had the lowest tensile strength, and that of 15% (w/w) CaCO achieved the highest strength values. Variant with 5% of filler content has the highest value of impact strength, approximately 168 J/cm, while the lowest value of impact strength can be found in the variant with 25% of CaCO, the hardness value decreased at the 25% CaCO.
