Fabrication of black printing toner through in situ polymerization: An effective way to increase conversion

Design and fabrication of an effective micromixer through passive method

Micromixer is a significant component of microfluidics particularly in lab-on-chip applications so that there has been a growing need for design and fabrication of micromixers with a shorter length and higher efficiency. Despite most of the passive micromixers that suffer from long mixing path and complicated geometry to increase the efficiency, our novel design suggests a highly efficient micr...

Membrane reactors: A way to increase efficiency

Nanocomposite Fabrication Through Particle Surface Initiated Polymerization

Magnetic nanoparticles (NPs) have attracted much interest due to their special physicochemical properties such as enhanced magnetic moment and coercivity different from the bulk and atomic counterparts. Incorporation of the inorganic NPs into a polymer matrix has extended the particle applications such as in high-sensitivity chemical gas sensors due to the advantages of polymeric nanocomposites...

Numerical simulation of toner jet method for nonimpact printing

The toner jet method has been previously proposed to perform electrophotographic nonimpact printing easily. To clarify the fundamental properties of this method, the jet behavior of toner is studied through simulation on a personal computer. The mesh electrode is assumed to be inserted halfway between the development roller and the paper-back electrode. This is done to control the locus and the...

Effect of Micro- and Nanomagnetite on Printing Toner Properties

Toner is a main component of electrophotographic printing and copying processes. One of the most important ingredients of toner is magnetite (Fe3O4) which provides the tribocharging property for toner particles. In this study, nano- and microparticles of Fe3O4 were synthesized using the coprecipitation method and different amounts of lauric acid as a surfactant. The synthesized nano and micro F...

Virtual overhearing: An effective way to increase network coding opportunities in wireless ad-hoc networks

Overhearing is of great importance to wireless network coding in that it can be exploited to obtain the side information needed for packet decoding. Recently, a new technique called virtual overhearing (VOH) was proposed to allow a node to obtain the packet sent by another node that is multiple hops away for free. This can overcome the limitation of overhearing and be used to discover more codi...
