The invention provides a feed-mixing wagon (1) for animal feed, comprising a frame with a drive, a container (4) with a continuous wall (5) with a feed-unload opening, a feed auger which is arranged in the container for mixing and cutting animal feed and comprising an auger shaft (8) and an auger body (10) which is arranged around it in a spiral which has several blades, wherein the blades comprise at least one blade (11) of a first, long type and at least one blade (12) of a second, short type, and wherein at least one blade of the short type is situated closer to the bottom (6) than at least one blade of the long type. As a result of the various blades in the described configuration, the cutting and mixing behaviour can be adjusted in an optimum way.

An apparatus for dissolving a gas into a liquid includes a liquid inlet for supplying liquid into the apparatus, a gas inlet for supplying gas into the liquid within the apparatus and a venturi arranged to dissolve the gas into the liquid passing through the venturi. The apparatus also includes an outlet for the liquid and dissolved gas downstream of the venturi. At least part of the liquid inlet, at least part of the gas inlet, at least part of the venturi and at least part of the outlet are integrally formed in a single piece of material.

A closed concentrated dry chemical dispersion system including a closed ingredient container having a volume of dry ingredient therein. The system provides a fluid container and a mixing chamber in which the dry ingredient and fluid can be mixed to form a formulation for delivery to a device such as agrochemical dispensing equipment. The system minimizes worker exposure to the chemicals and enables lower packaging and transportation costs.

An article for forming emulsion droplets includes a body having an inlet port, an outlet, and a reservoir configured to receive both an aqueous phase and an organic phase through the inlet port. By applying a force to the contents of the reservoir, an aqueous phase stream and a separate organic phase stream from the reservoir are generated and later combined to form emulsion droplets which are dispensed through the outlet, typically into a receptacle for analysis or further processing.

The present invention discloses polymer surfaces with T-shaped microstructure and their fabrication method and applications. The polymer surfaces with the T-shaped microstructure are characterized in that T-shaped microposts arrange orderly on them, and nanobulges arrange orderly on the top surfaces of the micronails of the T-shaped microposts. A flexible insert is designed and manufactured according to the geometry of the T-shaped microposts, and nanogrooves are manufactured on the cavity surface of an injection mold according to the geometry of the nanobulges on the top surfaces of the micronails. The flexible insert is mounted on the injection mold cavity. An injection molding machine is used to inject the molten polymer into the injection mold cavity. Then the polymer surfaces with the T-shaped microposts, on the top surfaces of the micronails of which the nanobulges arrange orderly, are molded. The polymer surfaces with the T-shaped microstructure exhibit robust Cassie-Baxter state and moderate surface adhesion to water droplets, and can be used for quantitative collection, lossless transportation or micromixing of microdroplets.

A “smart ” instrument for mixing (100), a microfluidic chip (50), and a system wherein they are used to prepare formulations is provided. The microfluidic chip comprises microchannels and a programmable data component. The system achieves optimal formulations for RNA, antisense, peptides and small molecules in the hands of even novice users.

The present disclosure provides approaches for reducing tobacco-specific nitrosamines (TSNAs) in tobacco. Some of these approaches include genetically engineering tobacco plants to increase one or more antioxidants, increase oxygen radicle absorbance capacity (ORAC), or reduce nitrite. Also provided are methods and compositions for producing modified tobacco plants and tobacco products therefrom comprising reduced TSNAs.

Described are microfluidic devices and methods for providing a predetermined number of microspheres or beads, together with a cell, within a fluid droplet being processed. The system may provide each droplet with a single bead and a single cell, and the bead may contain DNA or other reagents for later identifying the specific cell associated with that bead.

Microfluidic methods for barcoding nucleic acid target molecules to be analyzed, e.g., via nucleic acid sequencing techniques, are provided. Also provided are microfluidic, droplet-based methods of preparing nucleic acid barcodes for use in various barcoding applications. The methods described herein facilitate high-throughput sequencing of nucleic acid target molecules as well as single cell and single virus genomic, transcriptomic, and/or proteomic analysis/profiling. Systems and devices for practicing the subject methods are also provided.

A mixing device for preparing a ready-to-use compound comprising at least one component, which is to be mixed before use, in a cartridge with a tubular mixing rod and a working method with this mixing device and cartridge. The insertion of the cartridge in the mixing device is simplified so that the device can be operated completely automatically, and dispensing of a cartridge to be mixed or a ready-mixed cartridge is preferably be made possible with automated handling means (robots). Because the cartridge holder has a clamping means with which the cartridge can be clamped on the bottle neck-like section, the clamping of the cartridge in the mixer is simplified and can be triggered by force, for example pneumatically.
