Application

The wide liquid range of gallium was exploited recently when it was used as a solvent for the successful synthesis of ternary silicides, SmNiSi3 and YNiSi3, without incorporating Ga in their structure -- a promising new synthetic method.

Microbes have evolved elaborate iron-acquisition systems to sequester iron from the host environment using siderophores and heme uptake systems. Gallium(III) is structurally similar to iron(III), except that it cannot be reduced under physiological conditions, therefore gallium has the potential to

Discovery and Single Crystal Growth of Lanthanide Intermetallics—Interplay of Synthesis and Physical Properties

Solid state and materials chemistry have made a tremendous impact and have experienced growth in recent years, particularly for rare earthcontaining materials.

Working with Reactive, Volatile, Complex Materials to Produce Novel Alloys

Technologies are an integral part of our lives and we rely on them for such things as communication, heating and cooling, transportation, and construction. Improvements to technologies have made what they do for us more precise, automated, efficient, and powerful.

Lanthanide Ions as Photon Managers for Solar Cells

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).

Responsive Rare-Earth Materials and their Applications

The unique properties of the rare-earth elements and their alloys have brought them from relative obscurity to high profile use in common hightech applications.
