Control over the Electrostatic Self-assembly of Nanoparticle Semiflexible Biopolyelectrolyte Complexes

Electrostatic Self-Assembly of Nanodiamonds

Not all the crude agglutinates are crushable into primary particles by beads-milling. The most reliable criterion for the crushability of crude detonation product is zeta-potential in aqueous suspension, which must be higher than +50mV or lower than -50mV as determined on a Zetasizer Nano-ZS (Malvern Instruments, England). We use fluffy, grey-coloured fine powder made by Guangzhou Panyu Guangda...

Optimal control of electrostatic self-assembly of binary monolayers

A simple macroscopic model is used to determine an optimal annealing schedule for self-assembly of binary monolayers of spherical particles. The model assumes that a single rate-controlling mechanism is responsible for the formation of spatially ordered structures and that its rate follows an Arrhenius form. The optimal schedule is derived in an analytical form using classical optimization meth...

Microfabrication through Electrostatic Self-Assembly

We use electrostatic interactions to direct the patterning of gold disks having ∼10-μm diameters on functionalized surfaces. Planar and curved substrates with patterned surface charge were generated either by microcontact printing or by photolithography. Small charged gold disks were generated by electroplating gold into photoresist molds and derivatizing these disks with charged self-assembled...

Electrostatic self-assembly of binary nanoparticle crystals with a diamond-like lattice.

Self-assembly of charged, equally sized metal nanoparticles of two types (gold and silver) leads to the formation of large, sphalerite (diamond-like) crystals, in which each nanoparticle has four oppositely charged neighbors. Formation of these non-close-packed structures is a consequence of electrostatic effects specific to the nanoscale, where the thickness of the screening layer is commensur...
