Recommendations to John wolf on better ways of restructuring the purchasing process for the Wolf motors dealership network. John Wolf needs to find at least one mentor who has been in the same position and learn from him. It should be a time for John Wolf to stop dealing with disturbing customers both suppliers whose products yield less profit and customers who keep on nagging for lower prices.
The term "Janus Particle" was coined by author Leonard Wibberley in his novel The Mouse on the Moon as a science-fictional device for space travel. The term was first used in a real-world scientific context by C. In that work, the amphiphilic beads were synthesized by protecting one hemisphere with varnish and chemically treating the other hemisphere with a silane reagent.
This method resulted in a particle with equal hydrophilic and hydrophobic areas. Janus particles are named after the two faced Roman god Janus because these particles may be said to have "two faces" since they possess two distinct types of properties.
One year later, Casagrande and Veyssie reported the synthesis of glass beads that were made hydrophobic on only one hemisphere using octadecyl trichlorosilane, while the other hemisphere was protected with a cellulose varnish. Then several years later, Binks and Fletcher investigated the wettability of Janus beads at the interface between oil and water.
Twenty years later, a plethora of Janus particles of different sizes, shapes and properties, with applications in textile,  sensors stabilization of emulsions and magnetic field imaging  have been reported. Synthesis[ edit ] The synthesis of Janus nanoparticles requires the ability to selectively create each side of a nanometer-sized particle with different chemical properties in a cost-effective and reliable way that produces the particle of interest in high yield.
Initially, this was a difficult task, but within the last 10 years, methods have been refined to make it easier. Currently, three major methods are used in the synthesis of Janus nanoparticles.
After creating a monolayer of fluorescent particles, bilayers of 1: The wafer is then placed in a beaker with 2 ml DI water and sonicated for 2 h to resuspend them. Scale bar represents nm.

Ralph Lauren’s transport operations team lacked the ability to dynamically route international air freight according to real-time best service and cost options, and it showed in inflated shipping costs.
Two masking techniques are common to produce Janus particles, evaporative deposition   and a technique where the nanoparticle is suspended at the interface of two phases.
However, only the phase separation technique scales well to the nanoscale. These methods typically involve the liquid—liquid and liquid—solid interfaces, but a gas—liquid interface method has been described.
The magnetite nanoparticles aggregated at the interface of the water-oil mixture, forming a Pickering emulsion. Then, silver nitrate was added to the mixture, resulting in the deposition of silver nanoparticles on the surface of the magnetite nanoparticles.
These Janus nanoparticles were then functionalized by the addition of various ligands with specific affinity for either the iron or silver. In this method, hydrophobic alkane thiolate gold nanoparticles were placed in water, causing the formation of a monolayer of the hydrophobic gold nanoparticles on the surface.
Air pressure was then increased, forcing the hydrophobic layer to be pushed into the water, decreasing the contact angle. When the contact angle was at the desired level, a hydrophilic thiol, 3-mercaptopropane-1,2-diol, was added to the water, causing the hydrophilic thiol to competitively replace the hydrophobic thiols, resulting in the formation of amphiphilic Janus nanoparticles.
In this method, molten paraffin wax was substituted for the oil, and silica nanoparticles for the magnetite.
When the solution was cooled, the wax solidified, trapping half of each silica nanoparticle in the wax surface, leaving the other half of the silica exposed. The water was then filtered off and the wax-trapped silica nanoparticles were then exposed to a methanol solution containing amino- propyl triethoxysilane, which reacted with the exposed silica surfaces of the nanoparticles.
The methanol solution was then filtered off and the wax was dissolved with chloroformfreeing the newly made Janus particles. They exposed homogenous aminopropyl-trimethoxysilane functionalized silica nanoparticles embedded in wax to an ammonium fluoride solution, which etched away the exposed surface.
This can partially be corrected by using waxes with higher melting points or performing functionalization at lower temperatures. However, these modifications still result in significant loss.
The exposed-to-be-modified portion of particle surface can be adjusted by controlling the PDMS curing temperature and time, thus the embedment depth of the particles.BibMe Free Bibliography & Citation Maker - MLA, APA, Chicago, Harvard.
