This invention provides a novel composition for a two-component polyurea coating that effectively utilizes waste polystyrene plastic to improve key properties. The key technical solution involves incorporating a waste plastic solution (polystyrene dissolved in toluene) into a standard two-component polyurea resin, which is then mixed with a polyurea hardener. The key inventive feature is the ability of the waste polystyrene plastic to significantly increase the gel time of the polyurea coating, thereby extending its workability, and to improve its long-term tensile strength
This invention introduces a novel nanocomposite of ZnO2 / polypyrrole, designed for highly efficient degradation of dyes in industrial effluents. The key technical solution lies in the specific synthesis and combination of these materials to create a powerful catalytic agent. The key inventive feature is the composite's remarkable ability to achieve 100% dye degradation in both dark conditions (within 20 minutes) and light conditions (in less than 10 minutes) for a
This invention presents a novel, environmentally friendly, and economical method for degrading cyanide in solutions, primarily industrial wastewater. The key technical solution involves contacting cyanide-containing water with metal peroxides (barium peroxide, strontium peroxide, or their combination). The key inventive feature is the ability of these metal peroxides to effectively degrade cyanide, achieving 97-99.9% removal, even in the absence of light and without generating harmful sludge. This is achieved through the in-situ generation of hydrogen peroxide and reactive oxygen species by the metal peroxides, eliminating the need for external energy sources like UV light or additional reagents common in prior art.
This invention provides an innovative and environmentally friendly method for treating industrial effluents, particularly those containing challenging Azo dyes. The key technical solution is the synthesis of bimetallic bio-Pd/Fe core-shell aerobic granules within a sequential batch reactor. This involves a phased process: maturing aerobic microbial granules, then sequentially increasing sodium tetra-chloro palladate concentration to form bio-Pd nanoparticles, and finally adding FeCl3 to deposit bio-Fe, creating the unique Pd/Fe core-shell structure on the microbial granule surface.
This invention introduces a metal oxide nanoparticle-based ferricyanide nanocomposite as a novel, reusable redox mediator for biosensors. Traditionally, ferricyanide is used in liquid form, limiting reusability. The key inventive feature is the electrochemical synthesis of a solid film of nickel oxide nanoparticles and potassium ferricyanide directly on a carbon black-modified glassy carbon electrode (GCE). This solid-film approach allows the redox mediator to be reused, addressing a major limitation in developing point-of-care electrochemical sensors.
This invention introduces a novel pharmaceutical composition that delivers enhanced therapeutic efficacy at a reduced dosage, along with its production method. The core technical solution lies in combining a bioactive substance (like Amoxicillin) with a plant-based binder, specifically an extract of Ipomoea staphylina, which inherently possesses antibacterial properties. This innovative approach allows for a significant reduction in the drug's dosage (e.g., from conventional 500-1200 mg to 150-250 mg),
This invention introduces a novel aquasome formulation for sustained delivery of fibrinolytic proteins, like nattokinase, to treat thrombosis. The key technical solution involves a multi-component nanocarrier: ceramic nanoparticles (e.g., hydroxyapatite) form a core, coated with a carbohydrate layer (e.g., cellobiose), encapsulating the protein. The key inventive feature is the precise component ratio (1:3:0.00004 core:carbohydrate:protein) and unique coating/encapsulation, ensuring a slow and continuous release
This invention introduces a novel antimicrobial hydrogel for medical and industrial applications. The key technical solution involves encapsulating precisely synthesized silver nanoparticles (AgNPs) within a collagen-based hydrogel matrix. The AgNPs are prepared using a controlled method involving silver nitrate, sodium alginate, and citric acid, with optimized pH and heating, ensuring uniform, stable (5-10 nm, spherical) nanoparticles. The key inventive feature lies in this unique combination and synthesis, which provides controlled
This invention presents a novel bi-layer tablet formulation and preparation method designed to significantly enhance the bioavailability of atorvastatin, a cholesterol lowering drug. The key technical solution is a dual-layer tablet: one layer contains atorvastatin calcium (9 mg), and the other contains naringin (19 mg), acting as a bioenhancer. The key inventive feature lies in the tablet's dual-release pattern, where the naringin layer is designed to release first.
