Ebook "Polyelectrolyte complexes in the dispersed and solid state I: Principles and theory" is intended to extend the content of this former chapter by bringing together selected state-of-the-art contributions on principles and theory. Progress and new knowledge on theoretical aspects of electrosorption phenomena between PEL and oppositely charged surfaces and of the practically always apparent aggregation and clustering tendency of PEC particles are reviewed.

Ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles are of potential magnetic resonance imaging (MRI) contrast agents for tumor diagnosis. However, ultrasmall particle size or negative surface charge lead to relative short half-life which limit the utilization of USPIO for in vivo MRI contrast agents.

In the present study, for the first time, photodegradation of lindane compared with adsorption technique in water environment using synthesized TiO2-NPs was investigated. Some effective parameters for lindane removal by photocatalyst were systematically optimized. The mechanism of lindane removal using TiO2-NPs is also suggested on the basis of degradation kinetic and the change in surface charge.

The high capacity electrode material design with rapid charging/discharging and long life capability has become a critical issue and main concern in recent years. Nickel oxide (NiO) has received much attention in the field of energy storage as a cathode electrode material owing to its layered structure with large spacing, crystal structure, and high specific surface area.

While triboelectric nanogenerators (TENGs) made of biomaterials are becoming significant components of self-charged monitoring healthcare systems, most of them show low output performance and poor durability. Herein, a surfactant-free graphene oxide-polylactic acid (GO/PLA) nanocomposite with customizable honeycomb patterns was, for the first time, prepared via a scalable two-step solution method to achieve a power-boosted biocompatible TENG.

In this study, a surface-enhanced Raman scattering (SERS) substrate based on an octahedral nanostructure of cuprous oxide (Cu2O) was fabricated to probe methylene blue (MB) molecules. Cu2O nanocrystals were synthesized by the solvothermal process using ethylene glycol, which plays both roles of reductant and organic solvent.

Poor induction of mucosal immunity in the intestines by current Salmonella vaccines is a challenge to the poultry industry. We prepared and tested an oral deliverable Salmonella subunit vaccine containing immunogenic outer membrane proteins (OMPs) and flagellin (F) protein loaded and F-protein surface coated chitosan nanoparticles (CS NPs) (OMPs-F-CS NPs). The OMPs-F-CS NPs had mean particle size distribution of 514 nm, high positive charge and spherical in shape.

Spatially resolved optically stimulated luminescence (OSL) offers a means for rapid assessment of dose distributions in retrospective dosimetry and geochronology. Until recently, OSL imaging systems have largely been restricted to measurements of millimetre scale samples; this approach is not well suited for applications where the physical process of interest operates on centimetre scale (e.g., depth dependent trap eviction in exposed rocks, sediment mixing in soils, attenuation of gamma radiation, etc.).
