the current study presents synthesis and characterization of high impact polystyrene - tio2 nanoparticles mixed matrix membranes for separation of carbon dioxide from nitrogen. the solution-casting method was used for preparation of membranes. the nano mixed matrix membranes were characterized using scanning electron microscopy to ensure the suitable dispersion of nano particles in high impact ...

Diffusion-enhanced fluorescence energy transfer was used to study the structure of photoreceptor membranes from bovine retinal rod outer segments. The fluorescent energy donor was Tb 3+ chelated to dipicolinate and the acceptor was the 11-cis retinal chromophore of rhodopsin in vesicles made from disc membranes. The rapid-diffusion limit for energy transfer was attained in these experiments bec...

– A phenomenological model for the unbinding transition of multi-component fluid membranes is proposed, where the unbinding transition is described using a theory analogous to Flory-Huggins theory for polymers. The coupling between the lateral phase separation of inclusion molecules and the membrane-substrate distance explains the phase coexistence between two unbound phases as observed in rece...

Lanthanum zirconate (LZO) has high-temperature advantages including high melting point, low thermal conductivity and structure stability, which the potential to be used in insulation field. However, mechanical properties of LZO porous ceramics have limited further applications. In this work, nanofibrous membranes were prepared by electrospinning, preparation parameters PVP content, spinning vol...

We study the impact of induced pressure fields on water flow and salt rejection in nanopores produced MoS2 membranes. observe that permeability are not impacted by distance between pores. This result contradicts continuous fluid mechanics calculations microfilters, which indicates existence hydrodynamic interactions adjacent pores increase mobility. Our results suggest at this nanoscale, do aff...

Many prominent biological processes are driven by protein assembling between membranes. Understanding the mechanisms then entails determining the assembling pathway of the involved proteins. Because the intermediates are by nature transient and located in the intermembrane space, this determination is generally a very difficult, not to say intractable, problem. Here, by designing a setup with s...

In analyzing the low-angle X-ray diffraction patterns recorded from the normal and swollen my&n in frog sciatic nerve, a precise value is found for the centerto-center distance between the pair of membranes constituting the repeating structure in the myelin. The previously reported large increase in period when the nerve is put in hypotonic Ringer’s solution is shown to be accompanied by a smal...

A series of wound membranes of polyvinyl alcohol and recombinant spider silk protein (pNSR16) was prepared by electrospinning. The membrane was analyzed by scanning electron microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy. The result showed that the three factors that affected average fiber diameter from high to low were, voltage, flow speed, and solidification ...

Membrane systems that naturally occur as densely packed membrane stacks contain high amounts of glycolipids whose saccharide headgroups display multiple small electric dipoles in the form of hydroxyl groups. Experimentally, the hydration repulsion between glycolipid membranes is of much shorter range than that between zwitterionic phospholipids whose headgroups are dominated by a single large d...
