Vaccines that target one or more antigens to a cell surface receptor improve the antigen-specific humoral and cellular immune response. Antigen(s) linked to a domain that binds to a cell surface receptor are internalized, carrying antigen(s) into an intracellular compartment where the antigen(s) are digested into peptides and loaded onto MHC molecules. T cells specific for the peptide antigens are activated, leading to an enhanced immune response. The vaccine may comprise antigen(s) linked to a domain that binds at least one receptor or a DNA plasmid encoding antigen(s) linked to a domain that binds at least one receptor. A preferred embodiment of the invention targets HIV-1 env antigen to the CD40 receptor, resulting in delivery of antigen to CD40 positive cells, and selective activation of the CD40 receptor on cells presenting HIV-1 env antigens to T cells.

The invention describes novel addition-crosslinking silicone compositions containing: (1) organosilicon compounds having radicals with aliphatic carbon-carbon multiple bonds; (2) organosilicon compounds with Si-bound hydrogen atoms; (3) the accumulation of Si-bound hydrogen at catalysts promoting aliphatic multiple bonding; and (4) as filler, silicate hollow glass micro-balls with a silver coating, wherein more than 95 wt% of the silver applied to the hollow glass micro-balls is present as metallic silver.

The invention relates to the technical field of composite films, in particular to a composite film for a transparent back plate of a solar photovoltaic cell module and a preparation method thereof. The solar photovoltaic cell module transparent backboard composite film of the present invention comprises a first weather-resistant layer, a second weather-resistant layer and a base layer in sequence from top to bottom, and the first weather-resistant layer is a transparent weather-resistant PC film with a thickness of 25-100 μm; The second weather-resistant layer is a transparent weather-resistant PET film with a thickness of 150-300 μm; the base layer is a transparent linear low-density LLDPE film with a thickness of 50-150 μm. The present invention replaces the traditional PVDF film with a transparent weather-resistant PC film, which improves the weather resistance and light transmittance of the backboard it is applied to, not only reduces the cost, but also greatly reduces the environmental pollution caused by the fluorine film. EVA film has excellent adhesion.

The invention discloses an aerogel waterproof and heat-insulating coating as well as a preparation method thereof. The coating with fireproof and heat-insulating properties is prepared by adding aerogel powder and ceramic powder which are subjected to hydrophilic modification as well as adding aids and fillers according to different formula proportions, and the coating is prepared by utilizing theproperty characteristic of a three-dimensional network structure of the aerogel, so that the defect that the existing coating is only fireproof and is not heat-insulating is solved and the coating has the heat-insulating characteristic. Meanwhile, nanometer ceramic powder is added in the coating, the nanometer ceramic powder in the coating is heated to be ceramic, one expanded ceramic film is formed on the surface of a base material, one air layer is arranged between the film and the base material, contact between flame and the surface of a vehicle metal material product is isolated, and heatis prevented from being transmitted to the surface of the metal by depending on the low heat-conducting coefficient characteristic of the aerogel in the coating. Through fireproof and heat-insulatingsynergistic effect, good barrier effect on heat and flame is guaranteed to be achieved no matter normal use of the metal part in the vehicle or occurrence of extreme fire accidents, and the fireproofproperty of the coating is enhanced.
