A catalyzed chemimechanical-anthraquinone pulping of black spruce wood was investigated in this study. The effect of liquor pH on anthraquinone performance, AQ and mass transfer limitations on chemimechanical pulp properties and the effects of AQ, liquor pH and sulphite concentration on pulping kinetic were studied.<br>It was observed that AQ was not an effective redox catalyst when added to the sulphite liquor at pH 4, but it was very effective at pH 7 and higher. When chemical treatment of chemimechanical pulping was done with the presence of AQ, the sulphur content of pulp was reduced due t

The objectives of this work were to investigate and improve impregnation of regular (2-8mm thickness range) black spruce wood chips in CMP-AQ pulping. Impregnation and pulping experiments were performed while varying several pulping parameters. Experiments were analyzed in terms of yield, lignin content, percent screen rejects, and strength properties. The goal was to determine optimum pulping conditions that would improve chemical impregnation. Impregnation is a function of percent screen rejects: well impregnated chips have fewer rejects.<br>Cooking temperature and cooking time were held con

In this research the environmental effects related to the position of a redox moiety with the electrochemical double layer were studied. This project was made possible with the synthesis of a series of lengths of ferrocene derived alkanethiols, a series of lengths of ferrocene derived norbornylogous bridges and a series of lengths of anthraquinone derived norbornylogous bridges. The series of ferrocene derived alkanethiols were used to study the effect of gradually varying the polarity of the self-assembled monolayers (SAMs) surface on the standard electron transfer rate constant and formal po

Annotation:

Synthesizing bioactive small molecules by structural modification of 1,4-naphthoquinone was the primary goal of this research. Several bioactive compounds with anticancer, antifungal, and antibacterial activities were synthesized. All the synthetic protocols were optimized in such ways that do not require cumbersome purification. First, a new protocol for the synthesis of NQM111 was developed. NQM111 is a highly potent anticancer agent developed in our laboratory, but the old protocol does not provide enough quantity for in vivo study. Therefore, a new safe and improved method was developed wh

This thesis describes the effects of different solvents have on the extraction profile of natural dyes from dye plants: madder, weld, golden rod, and chamomile. HPLC has been used to build a fingerprint of each dye plant profile and thus used to compare to the profiles of back extraction from textiles for natural dye identification in historical artefacts. The use of solid phase extraction is compared to extraction methods with no purification step which is favourable for anthraquinone dyes but results in a major loss of glycosidic compounds when using yellow dyestuffs. Supported by 1H and 13C

Resident Canada goose (Branta canadensis) populations have increased in urbanizing regions of the eastern United States, where man-made ponds and lakes surrounded by managed turfgrass offer ideal habitats. High concentrations of geese in these areas may cause feces accumulation, outbreaks of zoonotic diseases, eutrophication of adjacent waterways, and spread of turfgrass weeds. Although repellents effectively deter geese from turfgrass areas, frequent mowing (e.g., as in corporate parks and golf courses) may impact the efficacy of repellents. We tested the effect of 2 different mowing schedule
