Raina Gough’s research focuses on the formation and stability of aqueous salt solutions on present day Mars. Mars is known to have abundant H2O in the gas (vapor) or solid (ice) phases, but it is not clear if liquid water can exist. In the past years, however, spacecraft on Mars have collected data suggesting that small amounts of liquid water may exist on the surface or in the subsurface for some portion of the Martian year. Salts such as perchlorates and chlorides are present in the Martian soil and may play a key role in stabilizing liquid water. We experimentally study the formation and stability of liquid salt solutions under low temperature conditions using Raman microscopy. We are particularly interested in deliquescence, which is a relative humidity-induced solid-to-aqueous phase transition. Beginning in 2016. Dr, Gough has been a participating scientist on the Mars Science Laboratory mission to Mars.
CHEM 1011 - Environmental Chemistry 1
Fall 2019 / Fall 2020
Introduces basic principles of chemistry with applications to current environmental issues including toxic chemicals, air and water pollution, energy sources and their environmental impact, and climate change resulting from the greenhouse effect. No credit given to chemistry or biochemistry majors for this course if students already have credit in any college-level chemistry course numbered 1113/1114 or higher.
CHEM 1021 - Introductory Chemistry
For students with no high school chemistry or a very weak chemistry background. Remedies a deficiency in natural science MAPS requirements and prepares students for CHEM 1113 and CHEM 1114 or CHEM 1400 and CHEM 1401. No credit given to chemistry or biochemistry majors for this course if students already have credit in any college-level chemistry course numbered 1113/1114 or higher. Department enforced prerequisite: one year high school algebra or concurrent enrollment in MATH 1011.
CHEM 1133 - General Chemistry 2
