Niobium’s use in Nuclear Reactors

Niobium, with a chemical symbol of Nb, is the lustrous light gray ductile metallic element that resembles tantalum chemically, and proves to be an extremely essential yet fascinating transition element. With an atomic number of 41, niobium combines strength, a high melting point, resistance to chemical attack, and a low neutron absorption cross-section. All of this promotes its use in the nuclear industry, especially in control rods of nuclear reactors. The prices of niobium are reasonable too, at a mere $75/lb, and are maintained by the largest producer to avoid market perception of a monopoly situation (Winter). Thus, niobium acts as a key element in nuclear fission reactors, due to its enormous strength, high melting point, resistance to corrosive chemicals,…

MRI and X-ray

Many people argue that the high cost of research outweighs its potential benefits. Provide one argument for and one argument against increasing current funding for atomic-structure research. Use specific examples from this lesson in your answers to support each position. The use of the MRI (magnetic resonance imaging) machine is a topic of debate with arguments for and against its use of this machine for medical purposes. An argument that supports the use of the MRI is that research in this field of atomic structure has already led to numerous advances that have provided great public benefit. An example is finding the soft tissue damage that an x-ray would not find because of the magnets, low radio wave frequency and…
