... Abstract A laminated-paper microwave food tray collapsed with hot food in it. Microscopic examination of the failed tray revealed no structural or material defects. Five additional trays of like construction were also tested to determine the conditions necessary to simulate the permanent...

... digestion for the range of ferrous and nonferrous materials typically encountered. The use of microwave-assisted acid digestion usually improves the efficacy and rate of the digestion process. Digestion vessels must be compatible with the acid mixtures. The ICP-OES spray chambers, nebulizers, and injectors...

... plasma-emission spectroscopy (ICP-ES) was used to determine the relative concentrations of metallic ions in the dry deposits. This wet chemistry technique, similar to IC, can give only the relative concentrations of the sampled dry deposits once they are dissolved using microwave techniques. The results...

... that require a coupling medium. X-ray, microwave, and terahertz methods have also found limited application when ultrasonic inspection is difficult or impossible because of the geometry or material properties of the material being inspected. Some chemical analysis-based methods such as Fourier-transform...

.... The dissipation factor, tan δ, which is given by: (Eq 5) tan δ = ε ″ ε ′ is a measure of the internal heating of plastics. Thus, little heating should occur in nonpolar or rigid materials (tan δ < 10 –3 ), whereas high-frequency (radio-frequency or microwave) welding necessitates that tan δ...
