leptospirosis is one of the most prevalent zoonotic diseases worldwide. currently, multivalent whole-cell leptospiral vaccines can induce protection against leptospirosis. therefore, preparation and formulation of new generations of vaccines that can stimulate long-term immunity for leptospirosis control are essential. the aim of this study was to prepare and characterize alginate microspheres ...

the effects of chitosan/biopolymer (c/p) and nanohydroxyapatite/ biopolymer (nha/p) weight ratios on particle size and its uniformity, cross-linking density and nh2 content of nano-hydroxyapatite/chitosan/gelatin (nha/c/g) microspheres were investigated. microspheres were fabricated using water-in-oil emulsion. cross-linking of microspheres was performed using water soluble carbodiimide. partic...

Modern branches of chemical production, which are associated with the development light industry, cosmetology, pharmacy, will require introduction new materials and coatings increased corrosionresistance thermal protection properties. Possible ways to solve this important scientific technical problem include finding resource-saving technologies, for authors consider use promising raw create com...

In order to reduce the hygroscopicity of ammonium dinitramide (ADN), four different ADN/nitrocellulose (NC) samples were prepared from acetone solutions using electrostatic spraying, with concentrations 2.5, 5, 7.5, and 10 mg ml−1. The morphology was analyzed by scanning electron microscopy, regular uniform size examined x-ray powder diffraction differential calorimetry investigate crystal stru...
