Due to the good chemical properties, polyoxymethylene dimethyl ethers (DMMn) are regarded as an outstanding additive component of diesel fuel, which are efficient in reducing the formation of soot during the combustion when added to diesel fuel. The properties, synthetic methods and application of DMMnare summarized and introduced in this paper. Furthermore, the development and application prospects of DMMnin future are presented.

A novel combination of single-electron transistors (SET) with MOS transistors is advanced to create inverter, which, compared with the pure SET circuit, is considerably augmented in its voltage gain and drive capability. Then a close analysis was conducted of the inverter, on the basis of which other logic gates were presented, thus achieving a circuit of two-bit digital comparator. The accuracy of the circuit is verified through the test on SPICE. This hybrid circuit shares the merits with both SET circuit and MOS circuit. Compared with the traditional circuits, this one uses fewer electronic components and is lower in power depletion.
