    Abstract: A device for capturing particles includes a gas-guiding unit, a gas-guiding unit and a mist-elimination unit. The gas-guiding unit has opposing first and second ends. The mist-elimination unit is disposed at the second end. The liquid-circulation unit, disposed under the mist-elimination unit by surrounding the gas-guiding unit, includes through holes below the gas-guiding unit by a gap. A gas containing particles enters the channel via the first end and then the mist-elimination unit via the second end. While the gas flows into the channel, the liquid in the liquid-circulation unit is inhaled into the channel via the gap to form droplets containing particles. After the droplets are captured by the mist-elimination unit, the liquid formed at the mist-elimination unit flows down into the liquid-circulation unit to reform the liquid to be further inhaled back to the channel of the gas-guiding unit via the gap.

    Abstract: A degradation method of thermosetting resin is provided. The method includes the following steps, for example, a first resin composition is provided. The resin in the first resin composition includes a carbon-nitrogen bond, an ether bond, an ester bond or a combination thereof. The first resin composition and a catalyst composition are mixed to perform a degradation reaction to form a second resin composition. The catalyst composition includes a transition metal compound and a group IIIA metal compound. The second resin composition includes a resin monomer or an oligomer thereof having functional groups. The functional group includes an amine group, a hydroxyl group, an ester group, an acid group or a combination thereof. A catalyst composition used in the degradation method and a resin composition obtained by the degradation method are also provided.
