Research in my laboratory is focused on synthetic and mechanistic transition metal chemistry.
My research interests include (1) creating transition metal — based drugs for treating the symptoms of malignant diseases, and (2) rigorously studying the chemical behavior of a particular transition metal in order to understand better the general principles governing the outcomes of chemical reactions.
Fossil fuels are really just dead organisms that once used the sun for energy and that have been under a great deal of pressure by being buried under rocks.
So, right now on Earth, we can't run our own nuclear fusion reactors, but we still rely heavily on the fusion reactions that take place on the sun.
This makes the already slightly unstable heavy atom even more unstable, which causes it to split into smaller atoms and possibly eject a few neutrons.
This releases a lot of energy because the original atom was so unstable.
Many fission reactions are initiated by a very heavy atom being hit (or, in chemistry lingo, bombarded) by a neutron.
The sun is essentially a fusion reactor creating energy by fusing hydrogen atoms together to form helium, and the sun is our primary source of energy.
We use the sun's energy for solar power, photosynthesis, and even in the fossil fuels we burn.
This article was published in the Journal of Geoscience Edeucation, Vol. Gains (pretest to posttest) among participants (n = 122) averaged 4%, similar to gains reported elsewhere.
In this study, a 15-item version of the Geoscience Concept Inventory (GCI) was used to assess the prior knowledge and learning of students enrolled in an introductory physical and historical geology course specifically designed for preservice elementary (K-8) teachers.
