چکیده
Development of synthesis protocols for realizing nanomaterials over a range of sizes, shapes and chemical compositions is an important aspect of nanotechnology. A number of recipes have been developed for the synthesis of metal nanoparticles in polar (for example, water) and non-polar organic solvents, each method accompanied by characteristic advantages and disadvantages. Specific applications often require the transfer of already formed nanoparticles from a polar to non-polar environment (and vice versa), thereby maximizing the advantages of both methods. In this article, I discuss how such nanoparticle phase transfers may be accomplished through imaginative use of capping molecules that modify the hydrophilicity/ hydophobicity of the nanoparticle surface.

متن کاملMechanical testing of isolated amorphous silicon slanted nanorods.
Mechanical testing was performed on a new class of nanostructures-amorphous Si slanted nanorods of rectangular cross section, fixed at one end to the substrate. These nanorods were grown spatially well separated on nano-pillars under the oblique angle physical vapor deposition technique. Various samples with different dimensions and inclination angles were tested in bending using an atomic forc...
