The green leafy vegetables (Mormodica involucrate, Bidens pilosa and Amaranthus spinosus) are economic; seasonal; locally grown and easily available; easy to propagate and store; highly nutritious food substances that form an important component of diets. This study applies a physiology based extraction technique (PBET) to mimic digestion of these(More)
The objective of this study was to (1) measure the concentration of four anions (Cl(-), F(-), [image omitted], and [image omitted]) and nine other elements (Al, Ba, Ca, K, Mg, Mn, Fe, Ni, and Si) in two nontraditional biopolymeric chemical stabilizers (EBCS1 and EBCS2), (2) investigate consequent environmental toxicity risk implications, and (3) create(More)
Influenced by their morphology, nanocrystalline nickel hydroxide and nickel oxide have important technical applications. A simple novel procedure allows for the preparation of α-Ni(OH)2 from nickel nitrate using hexamethylenetetramine (HMTA) as the precipitating agent. The product obtained is free of water, but contains intercalated nitrate and HMTA.(More)
