Abstract(E)	A membrane particulate filter made up of three-way catalyst (TWC) particles was fabricated in order to mitigate the exhaust gas emission and to achieve higher initial filtration efficiency. Agglomerate nitrogen suspended microparticles were deposited on the conventional particulate filter substrate under different superficial velocity (5-50 mm/s). In this article, a two-dimensional porosity measurement method which was investigated on cross-sectional view of TWC membrane particulate filter was presented. First, total pores area and apparent bulk area were analyzed by image processing program, and the result was validated by electron micrographs through FE-SEM. Parametric studies have been conducted and the average porosity were measured as approximately 59%.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.
