Abstract: A metal powder for 3D printer includes a plurality of metal particles. A particle size distribution of the plurality of metal particles has a maximum peak within particle diameters of 1 ?m to 200 ?m. The particle size distribution gives a difference D90?D10 of 10 ?m or more between D90 and D10, D90 denoting a particle diameter in which a cumulative percentage is 90% in volume proportion, and D10 denoting a particle diameter in which a cumulative percentage is 10% in volume proportion.

Abstract: The invention provides a powder that is easily redispersible in a liquid medium such as water. The powder contains a fluoropolymer. The fluoropolymer contains at least one group A selected from the group consisting of —SO2Y, —COOR, —SO3X, —SO2NR12, and —COOX, wherein Y is a halogen atom; R is a C1-C4 alkyl group; X is M1/L or NR14, where M is a hydrogen atom or an L-valent metal, the L-valent metal being a metal in group 1, group 2, group 4, group 8, group 11, group 12, or group 13 of the periodic table; and R1s are each individually a hydrogen atom or a C1-C4 alkyl group. The powder exhibits a dispersion of 50% or higher. The dispersion is calculated by filtering a composition obtainable by mixing the powder with water through a mesh having an opening of 20 ?m.

Abstract: The present invention provides a polymer electrolyte membrane having excellent strength, a small dimensional change, and a low membrane resistance. The polymer electrolyte membrane includes a porous film having pores and a polymer electrolyte contained in the pores. The porous film is obtained by copolymerizing tetrafluoroethylene and an ethylenic comonomer to provide polytetrafluoroethylene and then stretching the polytetrafluoroethylene. The porous film has an average pore size of greater than 0.20 ?m.

Abstract: Embodiments of the present invention relates to a track and trace (TT) device. The TT device includes a radio frequency identification (RFID) tag, a near field communication (NFC) tag coupled with the RFID tag, and protective materials to cover the TT device. The RFID tag includes an identifier that is unique among all RFID tags and is, therefore, only associated with a product in which the TT device is embedded in. The NFC tag is pre-encoded with location information of a registration server. To register the product, the registrant uses an NFC-enabled device to access the location information of the registration server and to display thereon a registration page generated by the registration server. The registration page is automatically populated with the unique identifier of the RFID tag. Once registration is completed, an account corresponding to the association of the registrant with the product is created and stored.

Abstract: A method, a system and an apparatus is configured for selectively accessing content at a device. A disabled NFC tag is attached to an electronic device capable of reading the NFC tag. While the NFC tag is disabled, the electronic device is able to read any other additional NFC tag as normal. When the disabled NFC tag is activated it is read by the electronic device and transmits stored data to the electronic device. In some embodiments, the NFC tag is activated by completing a circuit of the NFC tag. In some embodiments, the circuit is completed by depressing a button.
