  • Patent number: 8528384
    Abstract: The invention relates to a method for the determination of the pore-mouth size distribution at the surface of porous materials. (i) While the backside of the sample is purged with a gas, the sample is immersed into a liquid wetting agent. (ii) The gas pressure is gradually decreased, and the gas flowrate is monitored; or, the gas flowrate is gradually decreased, and the gas pressure is monitored. (iii) When the gas flow stops, the remaining pressure in the system corresponds to the largest pore-mouth size. (iv) The pore-mouth size distribution can be calculated through a “dry curve” and a “wet curve”, which are curves of the gas flowrate vs. pressure at the dry and wetted states of the sample. The calculation of the pore-mouth size and the pore-mouth size distribution is the same as that based on the conventional bubble point method. The measurement of the pore-mouth size of the porous materials is of great importance when they are used as the substrates for surface coatings.

  • Patent number: 8462556
    Abstract: A localized trapping multi-level memory cell operating method includes the following steps. First, a localized trapping memory cell with the initial threshold voltage of approximately 2.5V is provided. Next, an erasing operation is performed to obtain a negative threshold level having uniform charge distribution along the channel region. Taking into account the over-erasure issue in the erasing operation, a programming operation is performed to precisely adjust the threshold voltage to a predetermined level of ?2V to ?1V. Then, with this negative voltage as a new initial state, a corresponding programming operation is performed and electrons are locally injected into the storage layer. By controlling the quantity of injected electrons, the MLC storage is achieved.
