Chemical treatment of bread corn during milling process to eliminate insect contamination
… procedures employing infrared radiation and dielectric heating were possible methods for killing the insects in the corn. Another procedure recommended for this purpose was the use of the mechanical force to kill the insect by means of high speed centrifugal machines called "Entoleter" …

High Birefringence And Low Viscosity Liquid Crystals
… kinds of liquid crystal materials: positive dielectric anisotropic LCs, negative dielectric anisotropic LCs, and dual- frequency LCs. For the positive dielectric anisotropic LCs, we have developed some high birefringence isothiocyanato tolane LC compounds with birefringence ~0.4, and super …

Development of active microwave thermography for structural health monitoring
… potential for non-contact, selective and focused heating. During an AMT inspection, two heating mechanisms are possible, referred to as dielectric and induction heating. Dielectric heating occurs as a result of the interaction of microwave energy with lossy dielectric materials which results in …

Dielectric Measurements for Organ Cryopreservation
… rapid. One proposed warming technique employs dielectric heating using electromagnetic energy at microwave frequencies. Crucial to the design of any such rapid warming system are the electrical properties of the material to be heated. This dissertation describes two measurement systems that …

Characterization, Processing, and Synthesis of Extreme-Performance Continuous Carbon Nanotube Network Composites
… but exploited through the demonstration of dielectric heating in a microwave reactor, where we show fluid imbibed within the network can be boiled to induce swelling and exfoliation of CNT bundles (or conversely, this may be avoided) through optimization of the heating parameters and …

Effect of pretreatment on the breakdown of lignocellulosic matrix in barley straw as feedstock for biofuel production
… barley straw grind: radio-frequency (RF)-based dielectric heating technique using alkaline (NaOH) solution as a catalyst and steam explosion pretreatment at low severity factor. The pretreatment was applied on barley straw which was ground in hammer mill with a screen size of 1.6 mm, so as to …
