The article shows that the DNA damage by MoC[H.sub.3]([[eta].sup.3]-allyl)[(CO).sub.2](phen) complexes occurs by two mechanisms. Backbone cleavage via the abstraction of H1' and H5' from the deoxyribose moiety and base modification have resulted in G-specific cleavage through the formation of base-labile residues methylguanine, methoxyguanine and 8-oxo-G.

Several active-learning techniques and inquiry-driven laboratory exercises were incorporated in labs to determine the effects of these methodologies on the fundamental skills of the students. The practice has been found extremely useful for developing the learning abilities of the students.

Among the different components present in spent nuclear fuel, long-lived trivalent actinides are particularly difficult to separate from the shorter-lived lanthanide fission products due to their similar chemical properties. Selective extraction of americium from acidic solution (up to 2M HNO3) containing tenth molar quantities of lanthanides has been achieved using neutral pyridine-based ligands dissolved in polar diluents. Nitrogen-based Bis Triazinyl Pyridine (BTP) ligands are desirable for both their excellent An/Ln selectivity and incinerability. Results pertaining to ligand solubility, kinetics, hydrolytic stability, and extraction performance in various nitric acid environments are presented. [ABSTRACT FROM AUTHOR]

The article discusses the use of active-learning and guided-inquiry pedagogies in diversifying teaching methods in science, technology, engineering and math (STEM) fields. An exercise has been described that incorporates both active learning in the lecture and scientific inquiry in the laboratory. Scientific method in lecture has been reviewed and then students were taken to view the Mentos-Diet Coke fountain. 16 mint Mentos were quickly submerged into a freshly opened 2-liter bottle of Diet Coke. All experimental conditions were documented by students and a more formal discussion occurred in the lecture hall. Each group of students came up with their own hypothesis.
