What are rare earth elements, and why are they important?

https://www.americangeosciences.org...are-earth-elements-and-why-are-they-important

The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium.

Rare earth elements are an essential part of many high-tech devices. The U.S. Geological Survey news release "Going Critical" explains:

"Rare-earth elements (REE) are necessary components of more than 200 products across a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and televisions. Significant defense applications include electronic displays, guidance systems, lasers, and radar and sonar systems. Although the amount of REE used in a product may not be a significant part of that product by weight, value, or volume, the REE can be necessary for the device to function. For example, magnets made of REE often represent only a small fraction of the total weight, but without them, the spindle motors and voice coils of desktops and laptops would not be possible.

Okay. Their ores, however, are compounds.

I've heard of organic chemistry, and inorganic chemistry, what does "pure" chemistry involve in terms of elements...?
Click to expand...

It's a degree classification, pure as opposed to applied chemistry.

Pure chemistry is the theoretical study of chemistry. The definition of pure chemistry is to focus on research to advance one's knowledge and understanding of a chemistry principle or process. The basis for pure chemistry is a curiosity about why something happens and investigating that cause.

Okay... I would have thought that chemistry was a pretty much fully understood science by now...

Take just one example namely graphene, which was discovered by two researchers at Manchester University. Just look at the huge number of applications it is being used for currently and will be in the future.

Graphene, and it's cousin Carbon 60 (aka "Buckyballs"), are just finding new ways to arrange the molecular bonds of carbon atoms.

Just, now that's funny!

DESCRIPTION
What are the chemical aspects of graphene as a novel 2D material and how do they relate to the molecular structure? This book addresses these important questions from a theoretical and computational standpoint.

Graphene Chemistry: Theoretical Perspectives presents recent exciting developments to correlate graphene’s properties and functions to its structure through state-of-the-art computational studies. This book focuses on the chemistry aspect of the structure-property relationship for many fascinating derivatives of graphene; various properties such as electronic structure, magnetism, and chemical reactivity, as well as potential applications in energy storage, catalysis, and nanoelectronics are covered. The book also includes two chapters with significant experimental portions, demonstrating how deep insights can be obtained by joint experimental and theoretical efforts.

Topics covered include:

Graphene ribbons: Edges, magnetism, preparation from unzipping, and electronic transport
Nanographenes: Properties, reactivity, and synthesis
Clar sextet rule in nanographene and graphene nanoribbons
Porous graphene, nanomeshes, and graphene-based architecture and assemblies
Doped graphene: Theory, synthesis, characterization and applications
Mechanisms of graphene growth in chemical vapor deposition
Surface adsorption and functionalization of graphene
Conversion between graphene and graphene oxide
Applications in gas separation, hydrogen storage, and catalysis
Graphene Chemistry: Theoretical Perspectives provides a useful overview for computational and theoretical chemists who are active in this field and those who have not studied graphene before. It is also a valuable resource for experimentalist scientists working on graphene and related materials, who will benefit from many concepts and properties discussed here.
