The Effects of Lead Toxicity on Thyroid Hormone Physiology in the Developing Brains of Xenopus laevis Tadpoles
This dissertation focuses on the effects of lead (Pb) on the expression of thyroid hormone distributor proteins and how that affects the developing brain in Xenopus laevis tadpoles. Previous work has shown that Pb has the ability to dysregulate thyroid hormone (TH)-signaling in vertebrates and that …

Radioactive lead studies in the human
… of individuals to the toxic effects of chronic lead exposure has never been fully understood. As the major intake of lead in the human is from food and beverages, any variation between individuals of the quantity of lead absorbed from the gut, and of the distribution and excretion of this lead, …

Single-step, Atmospheric Pressure Chemical Vapor Deposition of Methylammonium Bismuth Iodide Thin Films
<p>Lead halide perovskites (CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> and its variants) are promising solar cell absorber materials. Though the reported power conversion efficiencies of lead halide perovskite solar cells (up to 21%) are competitive with commercial silicon solar cells, lead …
