Abstract: A series of ladder-type multifused arenes (hexacyclic, heptacyclic and nonacyclic units) and the synthesizing methods thereof are provided. The ladder-type multifused arenes are copolymerized with various electron-deficient acceptor units to afford various p-type low-band gap conjugated copolymers.

Abstract: A chemical mechanical polishing method is provided. The chemical mechanical polishing method includes steps of providing a plurality of semiconductor elements to be polished, obtaining a respective dimension of the each semiconductor element to be polished, and polishing the each semiconductor element according to the respective dimension thereof.

Abstract: A complex for serving diabetics to reduce the concentration of blood glucose is provided, including a transferrin and a metal ion (or an oxidized metal ion). The transferrin can carry the metal ion (or the oxidized metal ion) into cells of a patient, thereby encouraging glucose uptake by the cells and reducing the toxicity of the metal ion (or the oxidized metal ion). Furthermore, the complex has the capability of reducing insulin resistance, and therefore is available to treat high blood glucose in type 2 diabetes and reduce insulin resistance. A process for reducing blood glucose of a diabetic patient includes providing a composition comprised of a complex of transferrin and at least one metal ion. A dose of the composition is administered to the diabetic patient in an amount effective to encourage glucose uptake by the cells and reduction of glucose in the blood as the transferrin carries the metal ion (or the oxidized metal ion) into the cells of the diabetic patient.

Abstract: A second-order bandpass filter having an improved frequency response is disclosed, in which a grounding capacitor is connected electrically to a two-port network as a feedback path so as to provide two finite transmission zeros. With the two transmission zeros, signals of second harmonic frequency and GSM signals may be blocked out from the pass band of the filter and thus filtered out. As such, the filter may be utilized in wireless local area network (WLAN) application. Further, since no extremely small value component is used within the filter, the frequency response may not be influenced by a manufacturing process of the filter. In addition, the thus formed filter has a relatively smaller volume.
