    摘要: A method is disclosed for calibrating a capacitance of an apparatus for measuring dielectric properties of a part. The apparatus includes an electrically grounded chamber, a lower electrode disposed within the chamber and connected to a radiofrequency (RF) transmission rod, an electrically grounded upper electrode disposed within the chamber above the lower electrode, and a variable capacitor connected to control transmission of RF power through the RF transmission rod to the lower electrode. A method is also disclosed for determining a capacitance of a part through use of the apparatus. A method is also disclosed for determining a dielectric constant of a part through use of the apparatus. A method is also disclosed for determining a loss tangent of a part through use of the apparatus.

    摘要: The present invention relates to a three dimensional construct formed from non-biodegradable and non-cytotoxic polymers that provide an internal and external space for living cells to attach, proliferate and differentiate. The construct is composed of polymer struts and/or fibers which are joined together in a designed 3 dimensional pattern. The 3 dimensional cell culture construct (cell culture insert) is intended to be used together with cell/tissue culture plate, tissue culture flask, bioreactor and the like under normal cell culture conditions. The invention further provides methods of making the 3 dimensional cell culture construct. Finally, the invention provides kits comprising one or more 3 dimensional porous cell culture construct in a package together with other cell culture supplies, such as tissue culture plate and flasks.
