Controlling the wettability between the porous electrode and the electrolyte in lithium-ion batteries can improve both the manufacturing process and the electrochemical performance of the cell. The wetting rate, which is the electrolyte transport rate in the porous electrode, can be quantified using the wetting balance. The effect of the calendering process(More)
A two-photon stereolithgraphy process is an effective method to fabricate 3D polymer microstructures. However, additional functionality, such as electrical conductivity, must be realized to allow them to be used in functional micro-devices. Electrical conductivity is a fundamental requirement for transferring signals and powering microsystems. We report a(More)
We report on the fabrication and characterization of high-Q microtoroid resonators made of low-loss modified polymers by the two-photon stereolithography process. We found that polymer resonators can be fabricated in a high-speed process, and measurements showed a maximum Q factor of 2.8&#x00D7;10<sup>5</sup>.
