Resumen de: US20260112603A1
A carpet of carbon nanotubes (CNTs) extends from a conductive substrate. The CNTs are bundled, and the bundles are bonded to the substrate to create low-resistance connections. A polymeric adhesive around the bases of the bundles binds the CNTs to the substrate without interfering with the low-resistance connection. The bundles can be organized into interconnected walls defining an irregular mosaic of valleys.

0000 The present invention relates to a mucoadhesive polymeric prodrug comprising a partially succinated polyvinyl alcohol (PVA-SA) with adjusted amount of hydroxyl and carboxyl pendant groups, which form an ester and/or amide linkage with amino and/or carboxyl and/or hydroxyl groups of biologically active compounds such as proteins, peptides, synthetic chemical, or natural products compounds (e.g. doxorubicin as an antitumor agent and antifibrotic drug). Preferably, said biologically active compounds are cysteamine (CYS) as the aminothiol compound and one compound selected from the group consisting of doxorubicin (DOX), ketoprofen (KETO), or 4-hydroxybenzyl alcohol (HBA). Moreover, the simultaneous presence of both hydroxyl and carboxyl groups in the partially succinated polyvinyl alcohol (PVA-SA) chain of the prodrug enables the self-assembled formation of 50-260 nm particles from the linear macromolecules and thus the drug release can be prolonged or adjusted. The present invention also relates to improving the mucoadhesive properties of the polymeric prodrug by the regulation of the amount of conjugated aminothiol compound. Further, the present invention relates to the method for producing said mucoadhesive polymeric prodrug, and nanoparticles of the said mucoadhesive polymeric prodrug.

Resumen de: WO2026082054A1
The present invention provides an ultra-fine nanophosphorus-carbon negative electrode material prepared on the basis of in-situ high-temperature phase change in confined microcavities, and a preparation method therefor. The method aims at solving the problems of large volume expansion, poor conductivity, poor cycle stability and the like when phosphorus is used as a negative electrode material of an alkali metal-ion battery. By constructing confined microcavities on the surface of a porous conductive material and using a transient high-temperature phase change technique, phosphorus can be uniformly distributed and nanocrystallized. The method comprises: mixing phosphorus and a conductive porous material in a solvent, and then performing sand milling; forming solid particles by means of reforming and granulation; constructing confined microcavities by means of coating treatment; performing transient heating in a high-temperature apparatus, so that a phosphorus source is rapidly sublimated and uniformly distributed; and finally, performing heat preservation and conversion in a sealed container. In this way, the stability of the material is improved. The method not only enhances the utilization rate of phosphorus and the conductivity of the material, but also prolongs the service life of a battery and enhances the energy density of the battery, and has the advantages of simplifying a production process and reducing the production costs.

The present invention relates to single-crystal spherical carbon nanoparticles that are single-crystals, are spherical, and have an average particle diameter of 1 nm to 30 nm. The single-crystal spherical carbon nanoparticles of the present invention can generate fluorescence with a high fluorescence quantum efficiency when excited by a light in wide wavelength range from ultraviolet light to visible light, and have fluorescence quantum efficiency of 10% or more compared to conventionally known carbon nanoparticles. The single-crystal spherical carbon nanoparticles can be used for drug delivery, because they do not have toxicities to living organisms that compound semiconductors made of cadmium, selenium, tellurium, and the like have. Furthermore, since the single-crystal spherical carbon nanoparticles are spherical, they can be densely packed as electrode materials for solar cells and secondary ion batteries, and can be used for negative electrode for lithium ion batteries or electrode material for solar cells.
