This study presents a method for incorporating cholecalciferol of a poorly water‐soluble vitamin into poly(vinyl pyrrolidone) fibers by electrospinning. The poorly water‐soluble vitamin was incorporated into water‐soluble polymeric matrix of nanofibers with the rapid evaporation of solvent during the electrospinning process. The scanning electron microscope (SEM) images showed that the diameter of...
Novel carbon material with hierarchical porous network structures was made by a method of transformed in situ route based on eggshell membrane (ESM) under inert atmosphere. The structural, physical, and chemical properties were characterized by scanning electron microscopy, Brunauer‐Emmett‐Teller, and UV–visible. The results showed that materials were crosslinked with fibers in diameters ranging from...
