Recent Developments
Researchers are continually finding new applications where it can replace other less efficient, more toxic Lewis acids. Recently it has been tested in curing epoxies and other polymerisation reactions, and in polysaccharide synthesis. It has also been trialled in green solvents other than water, such as ionic liquids and supercritical carbon dioxide. To enhance recovery, researchers have developed La(OTf)3 catalysts stabilised by ion exchange resin or polymer backbones, which can be separated by ultrafiltration. Solvent-free systems are also possible with solid-supported catalysts.

Famous quotes containing the word developments:
“The developments in the North were those loosely embraced in the term modernization and included urbanization, industrialization, and mechanization. While those changes went forward apace, the antebellum South changed comparatively little, clinging to its rural, agricultural, labor-intensive economy and its traditional folk culture.”
—C. Vann Woodward (b. 1908)
“I don’t wanna live in a city where the only cultural advantage is that you can make a right turn on a red light.
Freedom from labor itself is not new; it once belonged among the most firmly established privileges of the few. In this instance, it seems as though scientific progress and technical developments had been only taken advantage of to achieve something about which all former ages dreamed but which none had been able to realize.”
—Hannah Arendt (1906–1975)
