Nano Gadolinium Oxide

Nanometer gadolinium oxide is a white powder with a very high melting point (~2420°C) and a density of about 5.407 g/cm³. It exhibits ferromagnetism at room temperature and possesses the highest magnetic moment of any rare earth element. It is insoluble in water but soluble in acids, with a cubic crystal structure. Gadolinium has one of the highest thermal neutron absorption cross-sections. Furthermore, the Gd³⁺ ion, with its 7 unpaired electrons, is the core component of MRI contrast agents. Storage sealed in a dry environment is advised.

Applications:

1. Medical Imaging: The primary precursor for gadolinium-based chelates used as T1-weighted contrast agents in Magnetic Resonance Imaging (MRI), significantly improving image contrast.

2. Nuclear Medicine: Used as a neutron absorber and in control rods for nuclear reactors. Also an additive in scintillator materials for neutron/gamma-ray detection.

3. Targeted Radiotherapy: In Neutron Capture Therapy, Gd-157 isotopes capture thermal neutrons, releasing lethal short-range radiation to precisely destroy cancer cells.

4. Magnetic Refrigeration: A key working material in room-temperature magnetic refrigerators, utilizing its giant magnetocaloric effect for high-efficiency, eco-friendly cooling.

5. Catalysis: Serves as a catalyst or co-catalyst in various organic reactions (e.g., alkylation, polymerization), enhancing efficiency and selectivity.
