The effects of methylmercury on breast cancer progression in zebrafish
(Wheaton College (Norton, Mass.), 2016)Breast cancer is defined as a group of malignant cells that originate in the breast and have the potential to spread to distant sites in the body, most commonly the liver, lungs, bones and brain. Many factors increase the ... -
Sulfur deposition on the Greenland ice sheet : sources and implications of MSA and sulfate since 1900.
(Wheaton College (Norton, Mass.), 2016)Ice cores contain records of both local and global changes to atmospheric chemistry. Glaciochemical data from three newly acquired ice cores from the western portion of the Greenland Ice Sheet (GIS) were used to create ... -
The effect of n-acetylcysteine on methylmercury treated breast cancer cells.
(Wheaton College (Norton, Mass.), 2016)In the absence of estrogen, metalloestrogens can activate the estrogen receptor and cause breast cancer proliferation in estrogen receptor-positive cells. Methylmercury (MeHg) is a metalloestrogen that is often consumed ... -
Method development for the spectrophotometric analysis of arsenic in aqueous media.
(Wheaton College (Norton, Mass.), 2015)The use of trypan blue was explored as a detection and quantification method for As(III). This procedure represents an improvement of the method described by Narayana et al. (2006) by using the shift in absorbance wavelength ... -
Analysis of the chemistry of making a leaded linseed oil paint.
(Wheaton College (Norton, Mass.), 2015)Leaded linseed oils are a binder for oil paints used in the authentic restoration and conservation of traditional paintings. Analytical methods were used to investigate the color change which occurs during the 18-day ... -
Behavior and occurrence of organic acids in Antarctic ice : methanesulfonic acid, acetic acid, and formic acid in ice cores from West Antarctica.

Asymmetric hydrogenation of acetamido cinnamate ester in water.
(Wheaton College (Norton, Mass.), 2014)This research aimed to investigate the DuPHOS-Rh catalyzed asymmetric hydrogenation of acetamido cinnamate ester using water as the sole reaction solvent. The attempted synthesis of acetamido cinnamate ester was carried ... -
Enantioselective hydrogenation of enol esters in water.
(Wheaton College; Norton, Mass., 2011-11-18)Significant work has been done using traditional organic solvents for catalytic asymmetric hydrogenations. Recently, there have also been reports of the successful use of alternative reaction media such as ionic liquids ... -
Chemical weathering along the Greenland Ice Sheet margin
(Wheaton College ; Norton, Mass., 2009)Chemical weathering is thought to be a major control on the concentration of atmospheric carbon dioxide and therefore on global climate. Past chemical weathering surveys have focused on continental rivers, and little ... -
The Role of Mercury Speciation in its Methylation by Methylcobalamin (vitamin-B12)
(Wheaton College ; Norton, Mass., 2008)Mono-methyl mercury (MMHg) travels through the food chain by means of bioaccumulation, and humans are exposed to this potent neurotoxin by consumption of contaminated fish and shellfish products. Although it is well ... -
A Chemical Investigation of the 18 Day Creation of Lead Oil.
(Wheaton College ; Norton, Mass., 2008)Lead oil is a paint medium used by conservators to restore oil paintings authentically to their original brilliance. Lead oil is a combination of linseed oil and lead oxide. Upon heating the solution darkens in color and ...
