Antibody-Based Receptor Targeting Using an Fc-Binding
Boron neutron capture therapy (BNCT) is a radiation method used for cancer therapy. Cellular uptake of boron-10 (10B) atoms induces cancer cell death by the generation of alpha particles and recoiling lithium-7 (7Li) nuclei when the cells are irradiated with low-energy thermal neutrons. Current BNCT technology shows effective therapeutic benefits in refractory cancers such as brain tumors and

The general applied objective of this project is to develop hydratable alumina-bonded castables of properties comparable to the high-temperature fired basic bricks. This work is focused on improving the sintering of the ceramic binding systems at relatively low temperatures ( 1300°C) through incorporation of ultrafine powders. Ultrafine magnesium aluminate spinel powders were synthesized
