Diffuse double-layer interaction for nonspherical colloidal particles
The DLVO theory of colloids is used to consider the stability of clay colloid particles. An approach to colloid physics using classical electrostatic methods is presented. Specifically, the electrical double layer is examined using computational methods. To this end, the Poisson-Boltzman equation …

Stop-flow lithography and its application to graphical encoding
Colloids of a few to tens of microns have shown great promise in various applications. For practical purposes, colloidal building blocks which self-assemble into operational device are sometimes desired. This preprogrammed assembly requires large quantities of colloidal building blocks with …

Increased Control over Gold Colloid Adsorption on Substrates for Colloid Displacement Lithography
Colloid displacement lithography is proving to be very effective in the designing of nanometer scale electronic devices. Precise control of the structure of matter at the nanometer scale has brought a revolutionary change in science and technology. The use of these nanometer scale devices ranges …

Synthese und Charakterisierung von Polymerbürsten-Oberflächen mit Gradienten und Strukturierung (Synthesis and characterization of patterned and gradient polymer brush surfaces)
… of the mixed polymer brushes, adsorption of colloid particles. The second approach for the preparation of laterally resolved tethered layers consists of a novel strategy for reversible environment-responsive lithography. This strategy implies local fixation of the morphology of mixed polymer …

Sustainable development of an integrated solid waste and wastewater treatment.
… System (SEWTS), a system that agglomerates colloid particles and demulsifies oil that removed 99.9% of TPH from Sureclean interceptor effluent; and the Sureclean Advanced Water Treatment System (SAWTS), an advanced oxidation process that was demonstrated to reduce the TPH of contaminated …

The effects of particle shape, size, and interaction on colloidal glasses and gels
… step seeded emulsion polymerization reactions, colloid particles of tunable shape are synthesized from polystyrene. In all, four particle shapes are studied referred to as spheres (S), heteronuclear dicolloids (hDC), symmetric homonuclear dicolloids (sDC), and tricolloids (TC). Two size ranges …

Aqueous core colloidosomes with a metal shell
Colloidosomes are microcapsules whose shells consist of colloid particles, which are coagulated by a stabiliser or fused by sintering. In recent years, they have attracted considerable attention because of their potential applications in a range of industries, such as food, bioreactors and …

Droplets in an Electric Field: Surface Rheology, Coalescence and Rebound
… such as asphaltenes, resins and hydrophobic colloid particles indigenous to crude oil, adsorbed onto the water-oil interface forming an elastic monolayer. Electrically driven coalescence has to overcome the interfacial elasticity to merge.</p> <p>We first study the electro-deformation of an …

Structure/processing relationships in vapor-liquid-solid nanowire epitaxy
… evaporation of Au thin-films, deposition of Au-colloid particles, pregrowth cleaning procedures and CVD growth conditions and times. Once controllable and repeatable Si nanowire epitaxy on Si substrates was established, we were able to focus on development of both III-V wires on Si substrates as …

Synthesis of reponsive homo- and block copolymers - application to the generation of inorganic-organic nanohybrids
… preservation and a high shape-persistence of the colloid particles, even when exposed to non-selective environmental conditions. The synthesis of poly(N-isopropylacrylamide) (PNIPAAm) was investigated by ATRP for subsequent polymer-protein nanohybrid generation. This temperature-responsive polymer …
