Magnesium aluminate spinel is one of the most investigated inert matrix materials, due to its good physico-chemical stability, resistance against neutron irradiation, and its thermal conductivity comparable with conventional UO2 fuel. At the HFR in Petten various combinations of actinides and spinel have been tested within the EFTTRA programme, with the object to study the transmutation of amer...

Component concentration of sodium aluminate solution is an important quality index for alumina production. In this article, we propose a new on-line soft sensing strategy for measuring component concentration of sodium aluminate solution. With this method, on-line control can be realised in aluminate production plants. Several advance techniques are used, such as principal component analysis (P...

   Zinc oxide (ZnO) is the most common and widely utilized nanomaterial for biological applications due to their unique characteristics, such as biocompatibility, biosafety and antimicrobial along with thermal stability and mechanical strength. Magnesium (Cu) is considered as a significant dopant for ZnO due to their almost similar ionic radii and their role in biological activitie...

Nanomaterials with their three-dimensional structure and defined size and shape are considered to be suitable candidates for proper alignment with prochiral substrates for unidirectional introduction of reacting species to induce an asymmetric center. We herein report the design and development of a truly recyclable heterogeneous catalyst, nanocrystalline magnesium oxide, for the asymmetric Hen...

The effect of calcium treatment on inclusions in H08A welding rod steel was studied by industrial experiment and using thermodynamics theory. effects inclusion composition, morphology, quantity, size before after were metallographic microscope, scanning electron microscope (SEM), energy dispersive spectrometer (EDS). Thermodynamic studies show that the addition can form various forms xCaO·yAl2O...
