Seed Germination Performance and Seed Coat Mucilage Production of Sweet Basil (Ocimum basilicum L.)
… particularly during field seeding at cold soil temperatures. The germination of six cultivars (\'Italian Large Leaf\', \'Italian Large Leaf\' 35X, \'Nufar\', \'Genovese\', \'Genovese Compact Improved\' and \'Aroma 2\') of sweet basil seeds were tested on a one dimensional thermo-gradient table …

Specific ion effects on transient polymers: a new strategy for programmable microcapusles
… transient polymer microcapsules with a low-ceiling-temperature polymer, cyclic poly(phthalaldehyde) (cPPA), as the shell wall materials. Chapter 3 described an ion co-activation effect that modulated cPPA depolymerization rates in the presence of acid. In Chapter 4, we further investigated …

Computational investigation of flahover mechanisms using fire dynamics simulator (fds)
… at the floor level and average upper layer temperature of 600℃ were, in most cases appropriate regardless of ceiling height and the configuration of ventilation. However, the results suggest that a ceiling temperature of 600 °C is not a good general criterion for flashover. With increasing …

Polymeric thin films by chemical vapor deposition for the microelectronics industry
… stable diradical species formed by PX at room temperature, confirming thermodynamic predictions. This system also allows the calculation of reactivity ratios of PX with vinylic comonomers. A model is developed in which reactivity ratios can be determined if the following quantities are known: …

Intraspecies typing of orthopoxviruses
… In biological tests, one of the six showed the ceiling temperature, rabbit virulence, cytopathic effect in cell monolayers and sensitivity to anti-vaccinial serum which is characteristic of vaccinia, and is regarded as an isolate of vaccinia. The other five had a lower ceiling temperature, were …

Development and characterization of polyphthalaldehyde for transient applications
… sulfone) (PVtBCS) forms acid at moderate temperatures (ca. 85 °C) in the presence of water and also depolymerizes into purely volatile products. Upon heating to 85 °C, the PVtBCS/cPPA films generated acid and began to depolymerize and evaporate due to volatility of the monomeric …

Advanced manufacturing of sustainable materials
… an engineering thermoplastic with a low ceiling temperature, cyclic poly(phthalaldehyde) (cPPA). cPPA depolymerization proceeded under mild thermal conditions, and quantitative recovery of the monomer was possible. Direct repolymerization of the recovered monomer yielded high-quality …
