Length Scale effect of PCL-PB-PCL on the Light Scatteringand Dynamics of Network
polymer content. Measurements of the diffusion coefficient by dynamic light scattering (DLS)
show different relaxation in mixed systems. The fast diffusion coefficient increases with
increasing of polymer concentration. At higher polymer content...
Effect of Dipalmitoylphosphatidylcholine on A Microemulsion
at different concentration. Small angle X-ray scattering measurements revealed that the morphology of droplets changed from cylindrical to spherical with increase of lipid amount in the droplets. The same effect was observed in the mixture of water droplets...
Mixture of cholesterol-end capped polyethylene glycol with DSPC Liposomal.
The dynamic of network of self-assembled liposome by end-capped polymer was investigated, with dynamic light scattering. The liposome network, physically cross-linked by mixed liposome solutions with three different lenght scale of cholesterol...
A neutron scattering soil moisture measurement system with a linear response
A prototype moisture measurement system was designed and constructed, based on neutron scattering, for
preforming measurements in the laboratory. The system consisted of a rectangular soil container, an 241Am/Be neutron source and two...
The effect of simultaneous size reduction and transient network formation on the dynamics of microemulsion
and slow diffusion coefficients showed a repulsive and an attractive interaction, respectively. The results of both small-angle x-ray scattering and dynamic light scattering suggested that fast relaxation is affected by size reduction and increasing...
Using Scatter Search Algorithm to solve a multi_objective Transportation problem_ a case study
on scatter search is proposed. In this problem operating costs as well as equality of services are considered. The solution procedure consists of developing feasible solutions, then improving the solutions by using the local and global search operand...
Superstring Scattering from O-planes
-point functions of these vertex operators at the projective plane PR_2 level. We show that the result can be written in the Veneziano-type formulae, with the same kinematic factor that appears in the D_p-branes amplitudes. While the scattering amplitudes...
Network of Nano-droplets by a Tri-block Polymer
Mixtures of oil in water nano-droplets with two molecular weights of a tri-block polymer was studied by quasi elastic light scattering and small angle X-ray scattering. The results showed, the size and interaction of droplets didn’t change...
Relaxations of Light Scattering in Mixture of PEG-PDMS-PEG Triblock Polymer with Water in Oil Nano-Droplets
ones at high polymer content. One fast (alpha relaxation) and two slow relaxations (beta and gama relaxations) were observed in mixture system by Quasielastic light scattering (QLS). At high polymer content the network formation leads to slowdown...
