One of the primary aims of the actinide community within nanoscience is to develop a good understanding similar to what is currently the case for stable elements. As a consequence, efficient, reliable and versatile synthesis techniques dedicated to the formation of new actinide-based nano-objects （e.g., nanocrystals） are necessary. Hence, a ＂library＂ dedicated to the preparation of various actinidebased nanoscale building blocks is currently being developed. Nanoscale building blocks with tunable sizes, shapes and compositions are of prime importance. So far, the non-aqueous synthesis method in highly coordinating organic media is the only approach which has demonstrated the capability to provide size and shape control of actinide-based nanocrystals （both for thorium and uranium, and recently extended to neptunium and plutonium）. In this paper, we demonstrate that the non-aqueous approach is also well adapted to control the chemical composition of the nanocrystals obtained when mixing two different actinides. Indeed, the controlled hot co-injection of thorium acetylacetonate and uranyl acetate （together with additional capping agents） into benzyl ether can be used to synthesize thorium/uranium mixed oxide nanocrystals covering the full compositional spectrum. Additionally, we found that both size and shape are modified as a function of the thorium：uranium ratio. Finally, the magnetic properties of the different thorium/uranium mixed oxide nanocrystals were investigated. Contrary to several reports, we did not observe any ferromagnetic behavior. As a consequence, ferromagnetism cannot be described as a universal feature of nanocrystals of non-magnetic oxides as recently claimed in the literature.

Energy model based on solar potential and the production of electrical energy through living plants' photosynthesis

引用

CLEAN ENERGY 2024年第3期8卷 116-126页

作者： Martinez, Raymond daniel Rodriguez Univ Metropolitana Fac Engn Dept Ind Prod Caracas 1073 Venezuela

Developing a sustainable energy model is imperative considering the current trend towards decarbonizing sectors worldwide. For this purpose, Venezuela was used as a reference to propose an energy model focused on taking advantage of plant photosynthesis through microbial-vegetable fuel cells together with an agro-photovoltaic system to enhance energy and agricultural production. Energy production from the cells was estimated using an average power density of 264 mW/m(2) over 4% of the areas destined for crops in the entire Venezuelan region, obtaining an annual production of 19.889 GWh/year. In contrast, the energy production of the agro-photovoltaic system was modelled using PVsyst software on 50% of the area used for the cells distributed throughout the states of Anzo & aacute;tegui, Gu & aacute;rico, Monagas and Portuguesa according to their meteorological conditions, solar irradiation and agricultural activity, resulting in 3 703 417 GWh/year. The resulting whole system proved to be able to cover >10 times the installed electricity generation capacity at a national level and, together with the tremendous scalability of the microbial fuel cells, it shows that Venezuela has a high potential for the production and distribution of clean energy.
