An In Vitro Study On Skin Protection Across The Uv Spectra, Cheyenne Boone Nov 2018

An In Vitro Study On Skin Protection Across The Uv Spectra, Cheyenne Boone

Posters-at-the-Capitol

Skin cancer is the number one cancer in the United States. Lack of awareness of how harmful UV radiation is could be the cause of the over two million cases reported since 2012. It appears that there is not a lot information on the active ingredients used in sunscreens. Some of the compounds have been linked to birth defects, hormone disruptions, and the bleaching of coral reefs. Samples of commonly used sunscreens (both sprays and creams), cosmetic foundation, essential oils, lotions, and three pure organic actives were tested at specific concentrations and ran through a UV spectrometer. The results have ...


Investigation Of The Exraction Processes And Performance Properties Of Kudzu Fibers, Bahrum Prang Rocky, Virginia Wimberley Jan 2018

Investigation Of The Exraction Processes And Performance Properties Of Kudzu Fibers, Bahrum Prang Rocky, Virginia Wimberley

International Textile and Apparel Association (ITAA) Annual Conference Proceedings

While kudzu was introduced into the Southeastern United states for soil erosion and increase of land fertility, the plant has become unmanageable and is rapidly spreading to Canada. Japanese traditional craftsmen extract long, white fibers by labor intensive practices not feasible for 21st century commercial fiber production. This research investigated extraction by boiling, retting or fermentation, enzymatic combinations, and mild chemical processes. Two types of fibers were resultant- soft fibers and compact woody fibers. These fibers types were assessed for microscopic visual appearance, elemental analysis using EDAX SEM, and tensile strengths for the four extraction processes. In all extraction cases ...


Energy Densification Via Hydrothermal Carbonization, Keri Noack Apr 2011

Energy Densification Via Hydrothermal Carbonization, Keri Noack

Festival of Communities: UG Symposium (Posters)

A process called hydrothermal carbonization (HTC), also known as wet torrefaction involves treatment of raw biomass in hot, pressurized water. HTC of woody biomass has been shown to significantly increase the energy density of the feedstock, producing a biochar, similar to coal, having up to 40% higher calorific energy content. Feedstocks investigated include Tahoe chips, Pinion/Juniper chips, Rice hulls, and Corn Stover pellets pre-treated at 215 °C, 255 °C, and 295 °C. Chemical analyses were conducted on the gaseous, aqueous, and solid HTC products. Energy contents of the solid biochar products were measured by calorimetry, and mass balances were ...
