Synthesis, characterisation and thermal conductivity of CuO - water based nanofluids with different dispersants

Particulate Science and Technology, 2019
The aim of the present work is to investigate the change in thermal conductivity and stability of copper oxide (CuO) water-based nanofluids, which are prepared by a two-step process, with different concentrations of anionic (Sodium dodecyl sulfate SDS ...

Decentralisation, Dispersal and Dispersion

South African Geographical Journal, 1974
Abstract The terms decentralisation, dispersal and dispersion are used extensively in the literature of regional economic development. The first may refer to the decentralisation of core areas, to the process of dispersal, or to the state of a spatial system. The second term is concerned mainly with process and the third with pattern but no consistency

Design of 2‐hydroxyethyl methacrylate‐functional macromonomer dispersants by semi‐batch cobalt chain transfer polymerization

AIChE Journal, 2019
Acrylic resins for automotive coatings are produced in nonaqueous dispersions (NAD) of nanometer size. These must be sterically stabilized by oligomeric dispersants, which are complex reactive oligomers possessing vinyl and hydroxyl functionalities ...

Metagenomic and metatranscriptomic responses of natural oil degrading bacteria in the presence of dispersants.

Environmental Microbiology, 2019
Oil biodegradation has been extensively studied in the wake of the deepwater horizon spill, but the application of dispersant to oil spills in marine environments remains controversial.

Dispersion-managed solitons at normal average dispersion

Nonlinear Optics '98. Materials, Fundamentals and Applications Topical Meeting (Cat. No.98CH36244), 1998
We find that in a dispersion-managed fiber, in which the strength of the dispersion management is above some threshold, solitons can exist with normal average dispersion. When the normal average dispersion is below some limiting value there exist two soliton solutions with the same pulse duration and different pulse energies.

New dispersion-decreasing dispersion management

SPIE Proceedings, 2004
In this paper, we introduce a new dispersion management method of realizing exponentially decreasing dispersion fiber by using only two kinds of segments of fibers with different dispersions connected together. Exponentially decreasing dispersion fiber is used to obtain the optimum soliton transmission situation.

Dispersion-managed breathers with average normal dispersion

Optics Letters, 1998
Analytic and numerical evidence is presented that demonstrates that a dispersion-managed breather can be supported in an optical fiber even when the average dispersion is in the normal regime. This nonlinear behavior, which is contrary to guiding-center theory, is shown to originate from the reversible dynamics associated with the strong quadratic ...

Dispersion-managed solitons with net positive dispersion

Optics Letters, 1998
Propagation of dispersion-managed solitons in the net positive-dispersion regime is studied. A new form of sideband generation that is due to perturbations is identified. Some collision anomalies are pointed out.
