Abstract: A biofilm composite carrier and a preparation method and use thereof are provided. The biofilm composite carrier includes a polyurethane framework, an adhesive and a functional material, wherein the functional material is adhered to the surface and pores of the polyurethane framework through the adhesive, and the functional material is a mixture of zeolite and tourmaline. The biofilm composite carrier is beneficial to the quick start-up and stable operation of the municipal sewage deammonification system under conditions of low temperature and low ammonium.

Abstract: In an embodiment, a flame retardant composition comprises 60 to 95 wt % of a polycarbonate; a polysiloxane comprising a repeat unit of the formula (7); wherein the composition comprises 0.5 to 2 wt % of the repeat unit of the formula (7) of the polysiloxane; wherein the polysiloxane is free of one or both of a vinyl graft and repeat units derived from a vinyl monomer; 9 to 18 wt % of talc; 5 to 15 wt % of a phosphorus containing flame retardant; 0 to 1 wt % of a phosphite stabilizer; and 0.1 to 2 wt % of an anti-drip agent.

Abstract: A solid delivery precursor is described, which is useful for volatilization to generate precursor vapor for a vapor deposition process. The solid delivery precursor comprises solid bodies of compacted particulate precursor, e.g., in a form such as pellets, platelets, tablets, beads, discs, or monoliths. When utilized in a vapor deposition process such as chemical vapor deposition, pulsed chemical vapor deposition, or atomic layer deposition, the solid delivery precursor in the form of solid bodies of compacted particulate precursor provide substantially increased flux of precursor vapor when subjected to volatilization conditions, in relation to the particulate precursor. As a result, vapor deposition process operation can be carried out in shorter periods of time, thereby achieving increased manufacturing rates of products such as semiconductor products, flat-panel displays, solar panels, LEDs, optical coatings, and the like.

Abstract: A computerized method of generating and transmitting a message to a plurality of recipient devices has the steps of obtaining a plurality of recipient multicast identifications (IDs) for the plurality of recipient devices, losslessly encoding the recipient multicast IDs into one or more codewords such that the total length of the one or more codewords is shorter than that of the recipient multicast IDs, generating the message by encapsulating at least the one or more codewords into a payload of the message, and transmitting the generated message to a network. When receiving such as message, a listener device decodes the one or more codewords to determine if it is a recipient.
