Polymer Nanocomposites with Interpenetrating Gradient Structure Exhibiting Ultrahigh Discharge Efficiency and Energy Density

Advanced Energy Materials, 2019
Poly(vinylidene fluoride) (PVDF) based polymer nanocomposites with high‐permittivity nanofillers exhibit outstanding dielectric energy storage performance due to their high dielectric permittivities and breakdown strength.

Density gradient quantum similarity

AIP Conference Proceedings, 2012
Computation of density gradient quantum similarity integrals is analyzed, while comparing such integrals with overlap density quantum similarity measures. Gradient quantum similarity corresponds to another kind of numerical similarity assessment between a pair of molecular frames, which contrarily to the usual up to date quantum similarity definitions ...

Density-Gradient Centrifugation

1998
In some cases, further separation of virus from the plant contaminants can be achieved by placing the clarified extract on top of a small volume of a sucrose solution in a centrifuge tube, the so-called sucrose cushion. Although the higher viscosity of the sucrose solution delays the virions reaching the bottom, the plant contaminants may be slowed ...

Population Density Gradient and Rent Gradient

1982
In Chapter 1 we considered the existence of location equilibrium conditions with respect to the environmental quality of each location, and in Chapter 2 we examined a model of the process of urbanization accompanied by environmental degradation. Both models make clear theoretically the motivation of individual behavior.

Density Gradient Ultracentrifugation Technique

2018
As a general, non-destructive, and scalable separation method, DGUC has recently been demonstrated as an efficient way of sorting colloidal nanoparticles according to their differences in chemical, structural, size, or morphology. After the introduction of basic concepts of density gradient ultracentrifugation, for the practical applications, there are
