Book Two Dimensional Self Assembly of Nanoparticles at Liquid Interfaces

Download or read book Two Dimensional Self Assembly of Nanoparticles at Liquid Interfaces written by Jiayang Hu and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: And, on the same time scale there is a concomitant decrease in the SAXS form factor from disordered nanoparticles. X-ray beam transmission at different vertical heights characterizes the heptane and DEG bulk and interfacial regions, while monitoring the time dependence of SAXS at and near the DEG/heptane interface gives a clear picture of the evolution of nanoparticle assembly at this liquid/liquid interface. These SAXS observations of self-limited nanoparticle monolayer formation at the DEG/heptane interface are consistent with those using the less direct method of real-time optical reflection monitoring of that interface.

Book Self Assembly of Nanostructures and Patchy Nanoparticles

Download or read book Self Assembly of Nanostructures and Patchy Nanoparticles written by Shafigh Mehraeen and published by BoD – Books on Demand. This book was released on 2020-11-04 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Top-down approaches are currently the main contributor of fabricating microelectronic devices. However, the prohibitive cost of numerous technological steps in these approaches is the main obstacle to further progress. Furthermore, a large number of applications necessitate fabrication of complex and ultra-small devices that cannot be made using these approaches. New approaches based on natural self-assembly of matter need to be developed to allow for fabrication of micro and nanoelectronic devices. Self-assembly of nanostructures is a dynamic field, which explores physics of these structures and new ways to fabricate them. However, the major problem is how to control the properties of the nanostructures resulting from low dimensionality. This book presents recent advances made to address this problem, and fabricate nanostructures using self-assembly.

Book Magnetic Nanoparticle Field Directed Self assembly

Download or read book Magnetic Nanoparticle Field Directed Self assembly written by Ryan Michael Schmidt and published by . This book was released on 2011 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Directed self-assembly of nanomaterials via external fields is an attractive processing tool for industry as it is inherently inexpensive and flexible. The self-assembly of magnetic nanoparticles in particular has gained much recent interest for applications ranging from biomedical imaging and targeted cancer therapy to ferrofluid mechanical damping devices, that rely on the state of aggregation and alignment of the nanoparticles. We utilize an oil-water platform to directly observe directed self-assembly of magnetic nanoparticles that are field ordered into two-dimensional mesostructures through the fossilized liquid assembly method. Our system consisted of polymer-coated iron-oxide nanoparticles which were assembled at the interface between a crosslinkable hydrophobic monomer oil, and water through the use of external magnetic fields, and then cured with UV light. In this study, entire magnetic flux field lines in various geometrical configurations were successfully modeled and mapped out by the magnetic nanoparticles, both in-plane and in perpendicular orientations utilizing FLA. As the microscopic behavior of magnetic nanoparticles is known through this first study, further work can then be conducted through the assembly of block copolymer/magnetic nanoparticle nanocomposites. The morphology of neat self-assembled block copolymers have been extensively studied and it has been proven that the molecular weight, volume fraction of the components, and the degree of segment incompatibility are the three independent parameters used to determine equilibrium morphologies. The assembled orientations of lamellar and cylindrical morphologies in particular develop specific directionalities depending on the natural interactions of the blocks with the substrate and surface. It has been shown that treatments such as UV-Ozone treatment of the substrate, mechanical shear, or electrical fields can force this directionality to be altered, however few methods have been developed to readily alter preferential morphologies through the use of magnetic fields. In order to provide preliminary results toward the validity of a magnetically driven reorientation process, systems of polystyrene-b-poly(methylmethacrylate) with varying molecular weights were loaded with up to 1% polystyrene coated cobalt nanoparticles. This study successfully showed that the particles can be loaded into the block copolymers without disrupting the morphology of the block copolymers, and also provided initial results that this method is plausible.

Book Directed Self assembly of Colloidal Particles Using External Fields

Download or read book Directed Self assembly of Colloidal Particles Using External Fields written by Manish Mittal and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis we demonstrate the use of external fields to direct the self assembly of anisotropic particles into controlled microstructure. Directed self-assembly by external electric field has the advantage that it leads to rapid assembly of particles, it is reversible and the interactions can be tuned by controlling the field parameters. However, the polarization mechanism of colloidal particles and its dependence on the properties of the particle and the medium is not well understood. We use optical tweezers to measure the interactions between particles as a function of medium salt concentration and field frequency. We identify the double layer relaxation as the dominant polarization mechanism. This enables us to reinterpret the order-disorder phase diagram, published earlier by Lumsdon and co-workers, and thus predict the electric field required to assemble particles given the size of the particles, the frequency of the field and the type and concentration of the counter-ion in the system. We study the application of external field to anisotropic nanoparticle assembly using zeolite particles. The assembly of disk-shaped zeolite particles is interesting from the perspective of both understanding how anisotropic particles respond in electric field and also to self-assemble a zeolite structure, a material with large number of industrial applications. Similar to spherical particles, the disk shaped particles also form a hexagonal close-packed structure by assembling in a side-to-side fashion with their long axis, the diameter, oriented along the field direction. However, due to the smaller size of particles the field strengths required to assemble these particles are higher than those used in interaction measurements. At high field strengths the particles also form a brush-like structure that grows from the electrode interface towards the bulk suspension. The assembly of particles near the electrode interface occurs due to an interplay between dipolar force and the drag force due to electro-hydrodynamic (EH) flow. In addition to generalizing the dipolar interaction mechanism to anisotropic particles, this work also demonstrates the challenges associated with the use of only electric field to self-assemble particles into a permanent structure. To form an irreversible structure under electric field we develop a combined field and flow directed technique for assembling anisotropic particles and show its application using ellipsoidal titanium dioxide nanoparticles. The colloidal suspension of titanium dioxide particles, confined between glass substrates, is allowed to dry in the presence of electric field. The electric field orients the particles and due to the evaporation of solvent micrometer thick particulate films deposit onto the glass substrate. The microstructure of the film is controlled by tuning the field strength and the field frequency. On varying the field frequency the particles undergo a parallel-random-perpendicular orientation transition with respect to the electric field direction. The optical and the mechanical properties of the film are dependent on the orientation of the deposited particles. This work demonstrates a novel method of assembling anisotropic particles using external fields and controlling the microstructure using field frequency. Although field-assisted convective deposition allows us to control the orientation of the particles, the thickness of the film cannot be precisely controlled and the electrode gap limits the area of the assembled region. Unlike external electric fields, flow fields are more scalable and could be used to deposit particles over a large area. We use a flow coating technique to deposit ellipsoidal titanium dioxide particles on a glass substrate. The film is deposited from a colloidal suspension confined between a fixed blade and a translating substrate. Both the microstructure and the thickness of the film are simultaneously controlled by varying the particle volume fraction in the suspension, the velocity of the substrate and the angle between the blade and the substrate. At volume fractions above the isotropic-nematic transition the particles in the film orient along the coating direction. At volume fractions below the isotropic-nematic transition the particles do not orient along the coating direction. The substrate velocity and the blade angle affect the shear and extensional stresses exerted on the colloidal particles, which determine the orientation of the particles in the deposited film. Thus, flow coating is a rapid and scalable approach for de- positing thin films of nanostructured material consisting of anisotropic particles. (Abstract shortened by UMI.).
