The section on rare earths (lanthanides) is also notably strong.
In this regard, the use of lanthanides provides a gamma of versatile paramagnetic probes, but still needs to be fully exploited.
The reason for the high potency of the lanthanides is probably partly due to their trivalency.
These series are, respectively, the lanthanides and the actinides.
Due to the lanthanide contraction of the elements in the sixth period, zirconium and hafnium have nearly identical ionic radii.
Lanthanide-mediated epoxidation has been successfully applied to cinnamates and -heteroaryl unsaturated esters.
Contrary to most other lanthanides, which have a close-packed hexagonal lattice, ytterbium crystallizes in the face-centered cubic structure.
Phosphors with lanthanide dopants are also widely used in cathode ray tube technology such as television sets.

MoreManaging Your Emotions
What makes me angry?
Mostly，l hate when someone tries to make someone else feel bad.
I have to admit that once, when l was actually called names.
l regretted doing this afterwards, but not full heartedly because l think l was provoked in that situation.
The most postive way of dealing with anger is talking about the problem.
l talk to someone who listens, or l'll write my thoughts down on paper.
Learning how to deal with anger as you're growing up is so important.
When you're younger, you might yell,or cry when you're angry, but as you get older, you're expected to handle your emotions much better.
Learning to control your emotion now will prevent you from doing something that you'll regret later on in life!
