Abstract: The present invention relates to a nitrogen-containing terpolymer biodiesel solidification point depressant, and a preparation method and application thereof. The preparation method includes the following steps: 1) respectively preparing methylacrylic acid high carbon ester and N-hexadecyl methacrylamide; 2) adding the methylacrylic acid high carbon ester, the N-hexadecyl methacrylamide, and vinyl acetate to a solvent, and adding an initiator for polymerization to yield a methylacrylic acid high carbon ester-N-hexadecyl methacrylamide-vinyl acetate terpolymer, i.e., a nitrogen-containing terpolymer biodiesel solidification point depressant.

Abstract: A device for sorting bio-particles by image-manipulated electric force includes a first substrate, a second substrate, a fluidic channel, one or more photosensitive layers and an inlet hole. The first substrate has a first conductive electrode, and the second substrate has a second conductive electrode. The second conductive electrode is disposed opposite the first conductive electrode. The fluidic channel is disposed between the first conductive electrode and the second conductive electrode. The photosensitive layer is conformally disposed on at least one of the surfaces of the first conductive electrode and the second conductive electrode. The inlet hole is disposed in the first conductive electrode and the first substrate, where the inlet hole includes a first opening close to the fluidic channel and a second opening away from the fluidic channel, and the surface area of the first opening is greater than the surface area of the second opening.

Abstract: A message sending method is disclosed. The message sending method includes: sending a client handshake message to a server, where the client handshake message carries identifiers of server certificates buffered by the client; receiving a server handshake message sent by the server, where when the server determines that the identifiers of the server certificates buffered by the client include an identifier of a certificate that the server is ready to use, the server handshake message carries the identifier of the certificate that the server is ready to use; searching for the server certificate corresponding to the identifier of the certificate that the server is ready to use, among the server certificates buffered by the client; and encrypting, by using a public key in a server certificate found by searching, a client key exchange message to be sent, and sending an encrypted client key exchange message to the server.

Abstract: Anode catalysts for conversion of hydrocarbon feeds in solid oxide fuel cell membrane reactors. An anode catalyst may be a mixture of a metal with a metal oxide, for example a mixture of copper or copper-nickel alloy or copper-cobalt alloy with Cr2O3. Mixed oxides can be prepared by dissolving into water soluble salts of the different metals, chelating the metal ions with a chelating agent, neutralizing the solution, removing water by evaporation to form a gel which then is dried, and finally heating the dried gel to form a mixed oxide of the different metals. The chelating agent can be citrate ions, and ammonia can be added to the solution until the pH of the solution is about 8. The mixed oxide so formed then is reduced, for example by hydrogen, to form a composite comprising the metal (Cu, Cu—Co, Cu—Ni) and metal oxide, here Cr2O3.
