    Notes: An investigation of the structure of the iridescent scales of the green hairstreak, Callophrys rubi, reveals an internal lattice which is probably cubic close-packed in form. We present a model which explains the formation of the lattice in terms of packing of spheres and surface tension forces and generalize these results to internal structures in other Lepidopteran scales.

    Reinforced tracheoles in three firefly lanterns: Further reflections on specialized tracheoles (1978)

    Notes: The structures of the lantern tracheoles of three genera of flashing fireflies are compared. All three genera have stiff, reinforced tracheoles which resist folding or collapsing under conditions which flatten more typical tracheoles. This common specialization supports the hypothesis that the tracheoles play a major role in flash control in these fireflies, especially as the morphological basis of the stiffening is different in the three genera. Study of the tracheoles of other tissues reveals that there is great variety in structure and flexibility of these vessels from tissue to tissue and organism to organism, suggesting that tracheolar specialization may be a general phenomenon, with the fine structure of these air tubes being tailored to the particular demands and conditions of the tissues in which they are found.

    Structure and development of iridescent butterfly scales: Lattices and laminae (1989)

    Notes: Iridescent butterfly scales are structurally colored, relying upon the interaction of light with detailed architecture to produce their color. In some iridescent scales, the reflective elements are contained within the body of the scale and come in two basic forms, lattices that produce diffraction colors (analogous to those produced by opal), and stacks of laminae that produce thin-film interference colors (analogous to those produced by soap or oil films). Both structures are remarkably complex and precise, yet each is only part of the total edifice built by the cell that makes the scale.To understand better how a cell can produce lattices or thin-film laminae, I studied the development of iridescent scales from two lycaenid butterflies. The presence of diffraction and thin-film scales in the same family (and in some cases on the same individual) suggests that the two types must be developmentally related; yet these results yield no clear explanation as to how. The diffraction lattice appears to be shaped within the boundaries of the scale cell by means of a convoluted series of membranes in which the smooth endoplasmic reticulum plays an important part. The thin-film interference laminae appear to result from the condensation of a network of filaments and tubes secreted outside the boundaries of the cell. This paper outlines the developmental histories of both types of scale and discusses the developmental implications of the mechanisms by which they form.

    Permeable sites in the firefly lantern tracheal system: Use of osmium tetroxide vapor as a tracer (1983)

    Notes: Flashing fireflies were permitted to breathe osmium tetroxide vapor, after which the lanterns were removed and the sites of absorption of the osmium into the tissues were detected in two ways: (1) by sonication to remove soft tissues, that is, those that had not been fixed by the osmium gas, and (2) by intensification with thiocarbohydrazide and silver nitrate, in a modification of the osmium-thiocarbohydrazide-osmium (OTO) stain technique. The results of both procedures indicate that the gas first enters into the tissues at the level of the tracheoles. These findings may be interpreted as underscoring the importance of the tracheolar cell and the tracheal end organ in the control of oxygen entry into the lantern tissues, and the implications of the results in the oxygen regulation theory of flash control are discussed.

    Fine structure of the tracheoles of the lantern of a photurid firefly (1977)

    Notes: The lantern tracheoles of the firefly, Photuris, are unusual in that their walls are reinforced by cuticular bars. The tracheoles are stiff and resist collapse under conditions which flatten more typical tracheoles. This reinforcement and the structural resemblance of the tracheal end cell to cells considered to be active in moving ions and fluid is taken as evidence suggesting that the flash may be turned on and off by control of the oxygen supply and that said control may involve some sort of osmotic mechanism.

    Interpenetrating polymer networks of poly(carbonate-urethane) and polymethyl methacrylate (1991)

    Notes: We report the synthesis and characterization of interpentrating polymer networks (IPN's), pseudo INPN's, and blends of urethane-containing aliphatic polycarbonates (PCU) and polymethyl methacrylate (PMMA). The simultaneous full IPN's of PCU's and PMMA over the whole composition range have only one Tg, as determined by DSC and DMA which, together with transmission electron microscopy observations, suggest a single phase morphology even though the linear chain blends are completely immiscible. The full IPN's exhibit a maximum tensile strength at a certain composition, and superior solvent and heat resistance as compared to the pseudo IPN's, linear blends, and the pure crosslinked PCU's and PMMA.

    Notes: Simultaneous interpenetrating polymer networks (IPN's), pseudo IPN's, and liner blends of aliphatic poly(carbonate-urethane) (PCU) and polyvinyl pyridine (PVP) have been prepared and characterized by DSC, DMA, and TEM. The full IPN's of PCU and PVP had a single phase morphology only above 50 wt % PCU, as determined by both DSC and DMA and confirmed by transmission electron microscopy (TEM). However, in both pseudo IPN's of PCU and PVP and in their linear blends there exist multiple glass transitions and melting points seen by DSC and DMA indicating phase incompatibility. The full IPN's exhibited superior ultimate mechanical properties and solvent resistance as compared to the pseudo IPN's, liner blends, and the pure crosslinked PCU and PVP networks.
