Rediscovery of the Elements: The Rare Earths - The Beginnings

Description: This article explores the rare earths, the chemically similar elements that occupy the f-block of the Periodic Table and the Group III chemical family. The articles shows the locations that certain rare earths were originally found. It also gives details on where the elements can be found currently, as well as major production areas. The cover of the Fall 2015 Hexagon journal (Vol. 106, Issue 3) features the Mountain Pass rare earth ore body in Southern California, which is mentioned in the ar… more

Rediscovery of the Elements: The Rare Earths - The Confusing Years

Description: This article gives a timeline of research conducted on the rare earths, 17 elements found in the f-block and Group III chemical family of the Periodic Table. It covers discoveries made after the success of Swedish chemist, Carl Gustaf Mosander. The article describes the categorization of the rare earths that took place after Mosander's time, as well as separation techniques that developed.

Redox Non-Innoence Permits Catalytic Nitrene Carbonylation by (dadi)Ti=NAd (Ad = Adamantyl)

Description: This article describes (dadi)Ti(X/L) species that manifest redox non-innocence (RNI), including a rare instance in which carbon monoxide does not affect redox activity at the metal, and does not bind, thus permitting its use as a substrate in catalysis.

Reduced Heart Rate and Cardiac Output Differentially Affect Angiogenesis, Growth, and Development in Early Chicken Embryos (Gallus domesticus)

Description: This article demonstrates for the first time that different processes in the ontogeny of the early vertebrate embryo (i.e., hypertrophic growth vs. development) have differential sensitivities to altered convective blood flow.

Reversing the Bricks: The Evolution of ETDs at UNT

Description: This presentation discusses electronic theses and dissertations (ETDs). Beginning in fall 1999, UNT has required the submission of theses and dissertations in electronic format. As an early adopter of what was to become the electronic thesis and dissertation (ETD) movement in higher education, UNT encountered and overcame several challenges in the pursuit of providing greater public access to the scholarship conducted at the University. Dr. Terrell was there from the very beginning, and will sh… more
