Dietary supplementation with Ceriporia lacerata improves learning and memory in a scopolamine-induced amnesia mouse model
Ceriporia lacerata (CL) is a species of white rot fungi. In this study, we have examined the beneficial effect of CL on scopolamine-induced memory impairment in mice. A freeze-dried CL mycelial culture broth was ...

Influence of the draw ratio on the mechanical properties and electrical conductivity of nanofilled thermoplastic polyurethane fibers
Electrically conducting textile fibers were produced by wet-spinning under various volume fractions using thermoplastic polyurethane (TPU) as a polymer and carbon black (CB), Ag-powder, multi-walled carbon nan...

Predicting the tensile strength of needle-punched nonwoven mats using X-ray computed tomography and a statistical model
As nonwoven mats are randomly oriented fiber assemblies, the tensile strength of nonwoven mats is determined by their microstructural factors, such as fiber orientation, fiber volume fraction, and fiber-fiber ...

Electrospinning fabrication and characterization of poly(vinyl alcohol)/montmorillonite/silver hybrid nanofibers for antibacterial applications
Poly(vinyl alcohol) (PVA)/montmorillonite clay (MMT)/silver (Ag) nanoparticles have been electrospun for fabricating PVA/MMT/Ag nanofiber in aqueous solutions. Since PVA is a water-soluble and biocompatible po...

Inhibition of bubble coalescence by the electrolytes
Coalescence frequency and coalescence time were measured in electrolyte solutions. Marrucci model was acceptable to predict the coalescence time of one pair bubble in the dilute solution of electrolytes. Trans...
