    Abstract: A method for manufacturing polycarbonate by melt-polycondensing bisphenol and carbonic acid diester uses as catalyst an alkali metal compound and/or alkaline earth metal compound (a). The catalyst is added to the bisphenol prior to the melt polycondensation, in an effective amount, i.e., the amount of alkali metal compound and/or alkaline earth metal compound (a) that acts effectively as a catalyst, is contained in said bisphenol, and is controlled to have the same catalytic activity as 1null10null8 to 1null10null6 mole of bisphenol disodium salt per mole of pure bisphenol A. The method conducts the reaction efficiently from the initial stage in a stable manner to obtain polycarbonate with good color, good heat stability and color stability during molding and the like.

    Abstract: Disclosed is a negative active material for a lithium secondary battery. The negative active material includes graphitized coke having a graphitization catalyst element and non-flat artificial graphite. The negative active material for a lithium secondary battery has good electrolyte-immersibility due to the gap between the graphite particles from graphitized coke having a graphitization catalyst element, and non-flat artificial graphite. Therefore, the present invention may provide a lithium secondary battery which has good high-rate capacity and initial efficiency.

    Abstract: Disclosed herein is a method of distributing a washcoat along channels of a particulate filter substrate, the method comprising: disposing a washcoat slurry comprising a catalytically active material within a channel of a particulate filter element such that a concentration of the catalytically active material varies anisotropically along the length of the channels. In one embodiment, a solids content of the washcoat slurry is selected to provide an anisotropic variation in the concentration of the catalytically active material. The washcoat slurry may be pushed a predetermined distance into the channels, the predetermined distance being less than or equal to the full length of the channels, and the pushing may be performed once. The solids content of the washcoat composition may be increased to provide an increase in a concentration of the catalytically active material proximate an end of the particulate filter substrate. Alternatively, the solids content of the washcoat composition may be decreased to increase the uniformity of in the distribution of the catalytically active material throughout a length of the particulate filter substrate.
