Melamine phosphate as a component of intumescent coatings
… has been shown to exhibit variations in its chemical constitution, and crystal shape and size, dependent upon the method of production. These crystal types have been incorporated with epoxy resin to produce intumescent coatings, which have been tested on a small scale fire testing device, …

Development and properties of tracheids and their cell wall layers in eastern hemlock (Tsuga canadensis L.)
Changes in anatomical, physical and chemical properties within developing and one-year-old increments were investigated in a 52-year old eastern hemlock tree, felled in the latter part of July, 1968. Based on available previous knowledge, the zones of xylem maturation stages were determined by the …

The urea adducts of the constituents of California montan wax
<p>Interest in the chemical constitution of montan wax began with the work of Von Boyen, who in 1901 showed montanic acid to be a constituent of the wax. In the years that followed the literature has been rich with respect to investigations of montan wax. Most of the literature concerns itself with …

Hydroxyl functionalities of middle rank british coals
… have a detailed and accurate knowledge of their chemical constitution and reactivity. Also, in the consumption of coals as chemical feed stocks, as in hydroliquefaction, it is advantageous to classify the coals in terms of chemical parameters as opposed to, or in addition to, carbonisation …

Direct selective laser sintering of aluminium alloy powders
… is possible is a significant result, as is the constitutional effect on this. The spheroidisation and oxide disruption phenomena in SLS/SLM processed aluminium powders arc suggested to be mainly controlled by the amount of oxide on the as-received powder's surface, the degree of the uniformity …

Single molecule studies of molecular electronics and biohybrid materials
… physics lies in understanding charge transport, chemical reactions, and polymer chain dynamics at the molecular level. In this thesis, I directly address these challenges using single molecule techniques. Recent advances in single molecule techniques have ushered in a fundamentally new …
