摘要:
Coatings aimed at improving an animal's health and well-being are provided. In particular, the coatings can help the animal manage its exposure to solar radiation, either through increased absorption of solar radiation in cold environmental conditions, or through increased reflectance of solar radiation in hot environmental conditions. In addition, or alternatively, the coatings can be used to deliver fragrances to mask the presence of bullers or protect the animal from infections or insects.

Isolated porcine epidemic diarrhea virus (PEDV) deposited under ATCC Accession No. PTA-121847, and attenuated strains generated by serial passage in culture of the deposited strain. Immunogenic compositions for reducing the incidence or severity of clinical symptoms from PEDV infection, and methods of making and using the same.
摘要:
Methods of preventing or decreasing PEDv and/or Salmonella bacteria in animal feed, feed ingredients, and pet food are provided. The methods utilize generally safe chemical mitigants, such as medium chain fatty acids, essential oils, and sodium bisulfate. The chemical mitigants are introduced to the feed or feed ingredients at inclusion rates selected so as to prevent or decrease PEDv and/or Salmonella bacteria in the animal feed, feed ingredients, or pet food. The methods are particularly suitable for use in post-processing treatment of animal feed, feed ingredients, or pet food that will be transported and stored for multiple days or weeks.
摘要:
Described are nanoparticulates comprising a metallic nanoparticle core and a peptide coating or shell encapsulating the nanoparticle core and being covalently bonded thereto. The coating is formed from a plurality of branched, amphipathic peptides, each comprising a polar/positively charged C-terminal segment, a branch point, and two hydrophobic N-terminal segments extending from the branch point. Methods of forming and using the nanoparticulates are also described. When a plurality of first and second peptides are added sequentially to the nanoparticle core, the peptides they self-assemble to form an interlocking peptide network bilayer where the respective hydrophobic segments of the peptides form beta-sheet structures in which the opposed sequences interlock to form a zipper- like structure in three dimensions.
摘要:
The creation of a nanoparticle solution from bulk materials in a one-step process is disclosed. Particles of the bulk material, typically in granular or powder or pellet form, having a particle size of on the order of 1 m or greater, are introduced into a specially-selected solvent and ligand solution and heated thereby directly producing nanoparticles having essentially the same chemical make-up of the bulk material.
摘要:
The synthesis of layered free-standing papers, films, tapes, and painted coatings. composed of acid-functionalized, few-layer molybdenum disulfide (MoS 2 ) and reduced graphene oxide (rGO) flakes for use as a binder-free conducting electrode in NIB applications are described. The mechanical and electrochemical performance of the layered free-standing papers is also described. Synthesis was achieved through vacuum filtration of highly homogenous dispersions comprising varying weight percentages of exfoliated MoS 2 flakes in graphene oxide in DI water, followed by thermal reduction. The electrochemical behavior of the composite paper was evaluated as a counter electrode against pure Na foil in a half-cell configuration. In addition, the unaxial tensile testing of the composite papers demonstrated their exceptionally high fracture strength.

The present invention describes subunit vaccines containing Gn and Gc glycoproteins of the Rift Valley Fever Virus, including nucleic acids encoding such glycoproteins, host cells, vectors, and immunoreagents generated with the glycoproteins, methods of vaccination, methods of diagnosis, and kits.
摘要:
Peptide-albumin hydrogels having a self-assembling, 3-dimensional nanofiber matrix are described. The nanofiber matrix comprises an amphiphilic peptide and albumin. The peptide comprises a terminal hydrophobic region, a central turning region, and a terminal hydrophilic region. Methods of making such hydrogels are also described, along with methods of using the hydrogels as scaffolding for tissue engineering, as 3-dimensional cell cultures, and for drug delivery, encapsulation of active agents (therapeutic cells, molecules, drugs, compounds), cell transplantation, cell storage, virus culture and storage.
摘要:
Reactant materials for use in the synthesis of compounds comprising a non-metal and hydrogen, and methods of making and using the same are provided. The reactant materials generally comprise first and second non-metals, a cation, and a transition metal, and can be formed and used in reactions occurring at relatively low-pressure conditions using heat energy that can be supplied via solar radiation. In particular, the reactant materials can be used in the synthesis of ammonia and various hydrocarbon compounds using air, water, and sunlight.

Gold nanoparticles having luminol covalently linked thereto and optionally functionalized with an oligonucleotide and bacterial or viral detection assays. In one aspect, the detection system for detecting an analyte in a sample comprises a light-shielding container having a fiberoptic cable for transmitting light generated within the light-shielding container to a photodetector; a plurality of functionalized nanoparticles deposited in solid form on or within a support, such that the support is located within the light-shielding container; wherein the functionalized nanoparticles comprise nanoparticles covalently attached to one or more chemiluminescent moieties; and a reagent system which causes the chemiluminescent moieties to produce light in the presence of the reagent system and the analyte in the sample.
