It was previously mentioned that the focus of this study is to use ceria-zirconia (CeO2-ZrO2) as the catalyst support. The approach of A. Poyraz et al. [7] to synthesize varying ratios of CeO2-ZrO2 mesoporous materials was modified and used. The modifications were the following: (a) zirconium (IV) oxynitrate hydrate was used instead of zirconium (IV) butoxide; (b) application of the method for the synthesis of CeO2-ZrO2 solid solution; and (c) physical separation of solids (filtration instead of

Tumor treatment by hyperthermia has limitations, however, that the most of nanoparticles do not have high specific absorption rate. At least 10% of tumor weight should be absorbed in order to be effective to heat-ablate tumors through hyperthermia. Treatment of malignant tumors at any site in the body is expected to be possible if agents that convert RF energy into heat can be delivered to the malignant cells. However, RF ablation suffers from the disadvantage that it is an invasive method that often

storage can be largely divided into: - mechanical storage: storage in a tank of compacted gas or liquid hydrogen; - physisorbtion : storage in a solid material by physisorbtion; comprise: - graphene and other carbon formation - metals and metallic nanocrystals and

SITE SPECIFIC DRUG DELIVERY Site specific delivery systems are unique forms of delivery systems whereby the drug or medicine is specifically or selectively delivered to a particular site in the body where it is going to exert it's action and it is not delivered to other non-target organs and cells. The main aim of site specific delivery of drugs is to develop drug concentration that is sufficient to produce therapeutic effect at the site of the disease with minimal effect to the rest of the organs
