results the results showed that the fiber diameter and the amount of loratadine affected the drug release and the disappearance time of nanofibers. the smaller the fiber diameter and drug amount, the faster the solubility and the release time of nanofibers. conclusions it was concluded that electrospinning can be a suitable method for preparing fast-dissolving loratadine nanofibers. materials a...

objectives: postsurgical adhesion is one of the common complications after surgery. some anti-adhesion barriers are commercially available which are not customary used by physicians as much as expected because of ineffectiveness. recently, nanofibers have been introduced as anti-adhesion barriers with the potential of drug delivery. in the light of role of inflammation and oxidative stress in a...

1550-7998=20 The polarization of the cosmic microwave background radiation will have a distribution of singularities and antisingularities, points where the polarization vanishes for topological reasons. The statistics of polarization singularities provides a nontrivial scheme to analyze the polarization maps that is distinct from the usual two-point correlation functions. Here we characterize ...

We show that doubly peaked electric fields are necessary to describe grazing-angle charge collection measurements of irradiated silicon pixel sensors. A model of irradiated silicon based upon two defect levels with opposite charge states and the trapping of charge carriers can be tuned to produce a good description of the measured charge collection profiles in the fluence range from 0.5×10 neq/...

UNLABELLED Electrospun fibers are being studied and developed because they hold considerable promise for realizing some advantages of nanostructured materials. The fibers can be made of biocompatible and biodegradable polymers. Electrospinning has therefore attracted interest in biotechnology and medicine, and there has been rapid growth in this area in recent years. This review presents an int...

Direct near field electrospinning is used to produce very long helical polystyrene microfibers in water. The pitch length of helices can be controlled by changing the applied voltage, allowing to produce both micro springs and microchannels. Using a novel high frequency variable voltage electrospinning method we found the helix formation speed and compared the experimental buckling frequency to...

– A theory is presented for the effective charge of colloidal particles in suspensions containing multivalent counterions. It is shown that if colloids are sufficiently strongly charged, the number of condensed multivalent counterion can exceed the bare colloidal charge leading to charge reversal. Charge renormalization in suspensions with multivalent counterions depends on a subtle interplay b...

Due to one-dimentional nanostructures’ unique properties and their intriguing applications, there has being a great demanding on the technologies which are able to produce such structures. Among the applicable strategies, electrospinning seems to be the simplest approach to generate continues nanofibers with ultrathin and uniform diameters (Li & Xia, 2004). Electrospinning is a spin technology ...

Electrospinning and galvanic displacement reaction are combined to fabricate ultra-long hollow chalcogen and chalcogenide nanofibers in a cost-effective and high throughput manner. This procedure exploits electrospinning to fabricate ultra-long sacrificial nanofibers with controlled dimensions and morphology, thereby imparting control over the composition and shape of the nanostructures evolved...
