Electrospinning combined with nonsolvent-induced phase separation is a simple and novel method to produce porous nanofibers. In the study, Poly (vinylpyrrolidone) (PVP) nanofibers were fabricated using an electrospinning approach complemented by compressed nitrogen (N). N2 was used as the nonsolvent of choice. Besides, the tun2ning of N2 pressure and temperature can impact the nanofibers’ morphologies by altering phase behavior and mass transfer. Also, the other parameters affecting electrospinning of polymer solution were discussed. The results were demonstrated by extending the technique to PVP/dichloromethane (DCM) and PVP/ethanol (EtOH) systems. And the binary phase equilibrium of solvents (dichloromethane or ethanol) and N simulated by ASPEN PLUS 2006 demonstrates that N is not a 2good choice for producing hollow or po2rous polymer nanofibers.

We report new results on blood flow modeling over large volumes of cortical gray matter of primate brain. We propose a network method for computing the blood flow, which handles realistic boundary conditions, complex vessel shapes, and complex nonlinear blood rheology. From a detailed comparison of the available models for the blood flow rheology and the phase separation effect, we are able to derive important new results on the impact of network structure on blood pressure, hematocrit, and flow distributions. Our findings show that the network geometry (vessel shapes and diameters), the boundary conditions associated with the arterial inputs and venous outputs, and the effective viscosity of the blood are essential components in the flow distribution. In contrast, we show that the phase separation effect has a minor function in the global microvascular hemodynamic behavior. The behavior of the pressure, hematocrit, and blood flow distributions within the network are described through the depth of the primate cerebral cortex and are discussed.
