Characterization of the Purity of Curcumin Extraction: Comparative study of UV Spectrophotometry and HPLC from a Field Application Perspective

Abstract: Turmeric is a popular spice used in South Asia for both culinary and religious purposes.  It has also been used in traditional Indian medicine called Ayurveda.  More recently curcumin has been identified to be the active ingredient in turmeric, and its pharmacological basis has been identified.  This paper examines the extraction, processing and refinement of curcumin with special emphasis on testing and characterization.  This study focuses on the comparison of UV Spectrophotometry and High […]

A Novel Method for Producing Silver Nanoparticles

Abstract: We created silver nanoparticles using silver nitrate and sodium alginate through a method of mixing and heating the two solutions. The nanoparticles were confirmed by spectrographs and electron micrograph investigations. They proved to be very effective inhibiting the growth of E.Coli when embedded in agar. A PDF version of this paper is available here. Introduction: Escherichia Coli (E. Coli) is a bacterial germ that inhabits intestinal tracts of humans and animals. The intestinal tract of […]

The Effects of Acid Rain on the Visible Light Absorption of Stained Glass

Abstract: The effect of acid rain on stained glass windows is felt by many churches and other historic buildings worldwide, especially in Europe. As a result, the relationship between the traditionally dark interiors of these European churches and the acid rain that corrodes the stained glass was studied. Specifically, the effects of specific pHs of acid rain on the visible light absorption of stained glass over time were examined. In order to study this topic, […]

Removal of Arsenic Contamination from Water Using Magnetite Nanoparticles

Introduction: Water contamination is a global problem that can result in illness and death. Consumption of contaminated drinking water is particularly problematic in third world countries where inadequate purification processes, coupled with rapidly increasing population growth and industrialization pose serious health risks. One of the most common and deadly contaminants found in water is arsenic (As). Arsenic, a heavy metal, is a key toxic contaminant in the drinking water supply of third world countries, often […]

Evaluation of Nitrate Retention Additives for Developing Environmentally Friendly Manures

Abstract: Activated carbon is a readily available material that can be added to fertilizers or manures to reduce nitrate nitrogen (NO3-N) contamination of surface and near-surface groundwater. To test the nitrate adsorption performance of activated carbon, its absorbance was compared to that of used wall board (gypsum), sand, carbon, iron filings, wheat litter, wood litter, coffee grounds, bauxite residue and vermiculite using a nitrate ion selective electrode.  Of these adsorbent candidates, only activated carbon exhibited […]
