Abstract The interfacial tension, phase morphology, and phase growth was determined for four polymer blend systems: polyethylene/polystyrene, polyethylene/polyamide‐6, polystyrene/polyamide‐6, and polystyrene/poly(ethylene terephthalate). Generally, high interfacial tension correlates with coarse phase morphology and…

Sub-micrometer-sized particles of poly(L-lactic acid) may be formed by using near-critical or supercritical carbon dioxide as an antisolvent to precipitate poly(L-lactic acid) from droplets of methylene chloride solution sprayed into a carbon dioxide continuous phase. Particle sizes may be controlled by varying the de…

The production of OH radicals by dissociation of water vapor in oscillating argon bubbles is studied theoretically to examine a possible mechanism for the emission of the 310-nm line observed in sonoluminescence experiments. Accurate models are used for the calculation of the temperature field in the gas and for the d…

Anhydrous glasses in the series x Li 2 O + (1 ‐ x )P 2 O 5 have been prepared and characterized in the range 0 ≤ x ≤ 0.5. FT‐IR spectroscopy and glass transition temperature measurements have been used to explore the structure and a key physical property of the low‐alkali phosphate glasses. The structure of v ‐P 2 O 5…
Diamonds grown by the temperature-gradient method using a nickel catalyst and sufficient nitrogen getter to produce barely detectable nitrogen absorption in the defect-induced one-phonon region have a deep brown colour which we show results from continuum absorption whose threshold lies around 1.7eV. In these diamonds…
The electrical conductivity of chemically synthesized and annealed polyaniline has been investigated. The room-temperature conductivity varies with the time and the temperature of annealing, and exhibits a maximum peak on its time-dependence curves for the polymer annealed above 120 °C. The time showing the maximum pe…

The effects of electrode resistance and electrochemical polarization on potential measurements made with reference electrodes in various locations are demonstrated for electrodes with full‐width tabs and idealized polarization characteristics. Nonuniform current distribution, which changes during discharge, can lead t…
The hydrolytically unstable polyphosphazenes, poly [(imidazolyl) (methylphenoxy) phosphazenes] and poly [ethyl glycinato) (methylphenoxy) phosphazenes], were studied as potential polymeric supports for cells in tissue regeneration. For bone repair, their specific function would be to support osteoblast growth, forming…
To meet the future goals of reduced emissions produced by gas turbine combustors, a better understanding of the process of formation of various pollutants is required. Both empirical and analytical approaches are used to provide the exhaust concentrations of pollutants of interest such as NOx, CO, and unburned hydroca…
