Abstract: Pulverulent compositions of a complex between an acid and a metal form an at least partially spherical particle. The acid is selected from 2-hydroxy-4-methyl-thiobutanoic acid (HMTBA), methionine, aspartic acid, the alginic acids, the pectinic acids, and the corresponding anions, in particular 2-hydroxy-4-methyl-thiobutanoate, methioninate, aspartate, the alginates and the pectinates. The metal is divalent or trivalent. The particle has an amorphous fraction the mass of which represents at least 50% of the total mass of the particle. The particle is substantially devoid of uncomplexed acid or anion and of uncomplexed metal or metal cation.

Abstract: An airship or airborne station comprises a gas-containing envelope for containing a lifting gas, solar panels on the envelope for providing electric power to an energy storage system, and an external display screen powered by the energy storage system. This airship or airborne station enables novel methods of using the airship or airborne station to display digital content, to sell or auction ad space on the display screen to the highest bidder, to display information for events, crowds, rescue operations, or to interact digitally with a group of wireless communications devices. Furthermore, the airship or airborne station acts as a communication and media hub for uploading user-generated content, relaying communications from wireless devices, broadcasting content or interactive media.

Abstract: The present invention relates to pulverulent compositions of a complex between an acid and a metal and the method of preparation thereof.

Abstract: In a method and system for forming microbeads, a polymer solution includes particles and a polymer dissolved in a solvent. A stream of the polymer solution flows into a chamber. A focusing fluid contacts and focuses the polymer stream in the chamber. The focusing fluid and the focused polymer stream flow, as a single flow stream, out from the chamber. Pendant droplets detach from a leading end of the single flow stream to form the microbeads. The focusing fluid reacts with the polymer solution to form functional groups at a surface of the microbeads for binding with biorecognition molecules. In the system, a flow focusing apparatus includes a flow focusing body shaped to define the chamber. Microbeads formed according to the methods and systems are also disclosed.

Abstract: In a method and system for forming concentrated volumes of microbeads, a polymer solution and/or suspension includes a polymer dissolved and/or dispersed in a medium. Streams of a focusing fluid and of the polymer solution and/or suspension flow towards a fluid bath, and into intersection with one another, so &s to focus the polymer solution and/or suspension. The polymer solution and/or suspension stream forms microbeads in the fluid bath. Some of the focusing fluid is drawn from the fluid bath, so as to concentrate the microbeads in die fluid bath. The system includes a flow focusing apparatus and a liquid-containing cell. The focusing apparatus includes polymer and focusing nozzles. The cell contains the fluid bath and has an outlet port, through which the focusing fluid is drawn from the fluid bath.

Abstract: The speed of a nucleic acid amplification reaction, such as the Polymerase Chain Reaction (PCR), can be increased by setting the temperature of heat sources above and below the desired denaturation, annealing, and extension temperatures. The reaction mixture is only contacted with the heat sources long enough for the desired temperatures to be reached.
