Titration Of A Newtown Creek Environmental Water Sample To Determine The Amount Of Chloride Ions [Chemistry], Kevin Mark Oct 2019

Titration Of A Newtown Creek Environmental Water Sample To Determine The Amount Of Chloride Ions [Chemistry], Kevin Mark

Open Educational Resources

Main Course Learning Objectives:

The General Chemistry 1 (SCC 201) course has multiple course learning objectives, which articulate key introductory chemistry concepts that all STEM students should possess. In particular, the Newtown Creek titration experiment aligns with SCC 201 learning objectives of:

  1. Demonstrate an appreciation of the role of chemistry in various aspects of life
  2. Perform basic laboratory skills such as the proper execution of titration techniques
  3. Describe and explain the fundamental chemistry concept of solution concentration
  4. Analyze and represent experimental data in tables and graphs, interpret experimental results and write laboratory reports

In the SCC 201 laboratory, students are …


9th Annual Postdoctoral Science Symposium, University Of Texas Md Anderson Cancer Center Postdoctoral Association Sep 2019

9th Annual Postdoctoral Science Symposium, University Of Texas Md Anderson Cancer Center Postdoctoral Association

Annual Postdoctoral Science Symposium Abstracts

The mission of the Annual Postdoctoral Science Symposium (APSS) is to provide a platform for talented postdoctoral fellows throughout the Texas Medical Center to present their work to a wider audience. The MD Anderson Postdoctoral Association convened its inaugural Annual Postdoctoral Science Symposium (APSS) on August 4, 2011.

The APSS provides a professional venue for postdoctoral scientists to develop, clarify, and refine their research as a result of formal reviews and critiques of faculty and other postdoctoral scientists. Additionally, attendees discuss current research on a broad range of subjects while promoting academic interactions and enrichment and developing new collaborations.


An Evaluation Of Elemental Composition Of Soils Associated With Ground Nesting Ants In The Family Formicidae In Somerset County, Maine, Haley H. Depner Apr 2019

An Evaluation Of Elemental Composition Of Soils Associated With Ground Nesting Ants In The Family Formicidae In Somerset County, Maine, Haley H. Depner

All Student Scholarship

Ants are keystone organisms and engineers in many ecosystems, playing an important role in nutrient cycling and rearrangement of organic and inorganic materials through foraging, waste management and, in subterranean species, nest construction and maintenance. In this study, I conducted elemental analysis of soils for calcium, copper, iron, potassium, manganese and zinc in and around the colonies of subterranean nesting ants. The two-step analysis used in this study utilizes the efficiency of X-Ray Fluorescence (XRF) Spectrometry to look for overall trends in elemental composition followed by Flame Atomic Absorbance (AA) to achieve higher resolution of select elements of interest as …


Student-Faculty Collaborative Research Grant Report, Megan Bestwick Feb 2019

Student-Faculty Collaborative Research Grant Report, Megan Bestwick

Post-Grant Reports

Mitochondria are essential organelles in most eukaryotic cells because of their role in metabolism and the production of ATP by the oxidative phosphorylation (OXPHOS) pathway, as well as other key cellular processes. Metal cofactors, such as copper (Cu) and iron (Fe), are incorporated into OXPHOS protein complexes of yeast located within the inner membrane of the mitochondria. Misincorporation or modulation of these available metals in mitochondrial enzymes leads to the production of reactive oxygen species (ROS). ROS are reactive molecules containing oxygen such as peroxides, superoxide, and hydroxyl radicals. Yeast are a good model for studying aging and the effect …
