A Colormetric Study Of Alizarin Red S
(1957-04-01)Spectrophotometry refers to the relative measurement of radiant energy or radiant flux as a function of wavelength. It applies not only to visual measurements, but also to photographic and photoelectric methods of measurement ... -
A Cooperative Approach to the N-Solution Problem
(2012-04-01)Collaboration is an ever-present element in scientific research today. Even within laboratories and research teams, colleagues need to analyze, interpret, and disseminate research outcomes individually. Despite this need, ... -
A Qualitative Analysis Of Electrical Discharge In Air
(1962-04-01)The purpose of this paper is to present the fundamental ideas of the gaseous electrical discharge and to experimentally verify those presented ideas. Chapter I deals with the theoretical description of the discharge in a ... -
A Quantitative Determination Of Iron Employing Gooch Crucibles
(1948-04-01)Generally iron ores are analyzed for their iron content by dissolving accurately weighted samples in hydrochloric acid, oxidizing the iron to the ferric condition, and precipitating it with freshly distilled or filtered ... -
A Study Of The Synthesis Of Polyvinyl Alcohol
(1967-04-01)Polyvinyl alcohol is a high molecular weight polymer whose repeating unit is CH2-CHOH. From this the expected monomer from which polyvinyl alcohol would be produced is vinyl alcohol, CH2=CHOH, however, vinyl alcohol does ... -
A Theoretical Interpretation Of Polarographic Studies Of The Cadmium Complexes of Thiourea and Methylthiourea In Dioxane-Water Mixtures
(1956-04-01)The purposes of this work ares a) to determine the stability constants for complexes of thiourea and methylthiourea with cadmium (II) ion by applying a definite correction factor to the best existing determination (1); and ... -
A Visual Guide to General Chemistry Topics
(2017-05-13)Using some of the most frequently asked questions during General and Essentials of Chemistry tutoring sessions, this compilation of illustrated worksheets and concept maps was assembled. Left black and white, the pages of ... -
Adsorption Of Human Hemoglobin Onto Chitin and Cellulose Surfaces
(2016-04-01)When a chitosan (chitin derivative) acetate buffer system is combined with a hemoglobin (Hb) acetate buffer system, three distributions of hydrodynamic radii are observed: Chitosan/H2O, Hb/H2O, and a third unexpected ... -
Approaches Towards the Syntheses of New Molybdenum Complexes as Models for the Active Site in Nitrogenase Enzymes
(2005-04-01)The present study aims to mimic the catalytic properties of the Mo center in the active site of the nitrogenase enzyme. The phosphorous-sulfur ligands PS3, PS3’ and PS3* were used to synthesize Mo-thiolate complexes of the ... -
Biochemical Analysis of Insect Camouflage in Manduca sexta, the Tobacco Hornworm
(2012-04-01)Manduca sexta (Tobacco Hornworm) larvae exhibit diet-induced adaptation, demonstrating green coloration in their natural environment but becoming a pale blue when placed on a lab diet lacking plant material. I hypothesized ... -
Comparative Chelate Stabilities By Potentiometric Titrations
(1959-04-01)A chelate is a particular type of a complex or coordination compound. When a metal ion occupies two or more places on an electron donor to form a ring, it is said to form a chelation compound, the electron donor being ... -
Dye Sensitization of TiO2 Single Electrodes
(2011-04-01)Solar power is the most widely available and abundant source of energy on the planet. Using solar power on a large scale to meet energy needs would require a significant reduction in the cost of solar energy conversion ... -
E Z Stereoisomerization in Methylene bis-Dithiocarbamate and N,N,S Trimethyldithiocarbamate
(2003-04-01)Rates of rotation about the carbon-nitrogen partial double bond in N,N,Strimethyldithiocarbamate (1) and methylene bis-dithiocarbamate (2) were measured by the dynamic NMR technique known as selective inversion recovery. ... -
Eddy Covariance Flux Determination of MBO Using the Fast Isoprene System
(2004-04-01)Experimentation into the dehydration reaction of 2-methyl-3-buten-2-ol (MBO) to 2-methyl-1,3-butadiene (isoprene) sought to utilize the Fast Isoprene System (FIS) for MBO eddy covariance flux measurements. It was hypothesized ... -
Efficacy of Silica Polyamine Resins in Remediation of Highly Contaminated AMD
(2008-04-01)Acid mine drainage (AMD) is an ongoing problem in Montana and remediation is very expensive. New silica polyamine resin technology offers an effective alternative to traditional polystyrene resins in terms of metal recovery. ... -
Electrophilicity of Cu-bound Nitriles: Toward a Method for [2+2+2] Cyclizations
(2014-04-01)Copper nitrile systems were explored to determine the change in nitrile nucleophilicity upon coordination to copper. Both Cu(I) and Cu(II) were explored. Complexes bearing electronwithdrawing nitriles and electron-donating ... -
Enhancing biofuel lipid feedstock accumulation in the microalgae Ostreococcus tauri
(2017-05-13)Microalgae produce a diverse array of biomolecules and have attracted attention as alternative sources for biofuel feedstocks. Unlike other forms of alternative energy resources, algae do not require arable land nor fresh ... -
