Abstract: The present invention relates to a method for preparing uniform metal oxide nanoparticles. According to the preparation method of the present invention, it is possible to maintain the temperature and pressure inside the reactor in a stable and constant manner by removing water generated in the reaction step for forming metal oxide nanoparticles. Thus, the uniformity of nanoparticles formed is increased, and the reproducibility between batches can be increased even in a repeated process and and a large-scale reaction. Therefore, the preparation method of the present invention can be used to synthesize uniform nanoparticles reproducibly in large quantities.

Abstract: The invention provides a process for exfoliating a 3-dimensional layered material to produce a 2-dimensional material, said process comprising the steps of mixing the layered material in a solvent to provide a mixture; applying energy, for example ultrasound, to said mixture, and removing the energy applied to the mixture, such that sedimentation of the 2-dimensional material out of solution as a weakly re-aggregated, exfoliated 2-dimensional material is produced. The invention provides a fast, simple and high yielding process for separating 3-dimensional layered materials into individual 2-dimensional layers or flakes, which do not strongly re-aggregate, without utilising hazardous solvents.

Abstract: COMMERCIALLY IMPORTANT RADIONUCLIDE GENERATORS UTILIZE AN ALUMINA SORBENT ON WHICH ADSORBED A PARENT RADIONUCLIDE. THE ELUATE FROM SUCH GENERATORS CONTAINS SIGNIFICANT QUANTITIES OF ALUMINUM IONS IN ADDITION TO THE DESIRED DAUGHTER RADIONUCLIDE. WASHING THE ALUMINA WITH AN ACETATE FIXING SOLUTION DURING THE PRODUCTION OF THE GENERATORS SUBSTANTIALLY REDUCES THE ALUMINUM ION CONTENT OF ELUATES OBTAINED THEREFROM.
