Mesostructured oxide films were prepared by dip-coating from colloidal solutions on ultrathin Si wafers and solidified by heating at various temperatures. Two-dimensional small-angle X-ray scattering measurements were carried out in transmission under selected tilt angles and evaluated by comparison with analytical expressions. The films are composed of oriented mesophases, the structures of which are defined in terms of lattice type, preferred orientation, deformation and imperfection, notably stacking faults.

AbstractSuperlattices of nanoparticles are generally produced based on solution chemistry processes. In this paper, we demonstrate that self-assembled monolayer structures of nanoparticles with superlattice periodicities can also be produced on template-free surfaces in the gas-phase cluster beam deposition process. It is found that the packing of Fe nanoparticles corresponds to an average of two-dimensional densely packed lattice with a hexagonal summary. By controlling the nanoparticle coverage, the two-dimensional densely packed monolayer morphology can spread to the whole substrate surface being deposited. A formation mechanism of the ordered monolayers is proposed. The densely packed morphologies are formed by the balance between the diffusion rate of the nanoparticles and their filling speed on the substrate surface determined by the deposition rate, and the ordering of the nanoparticle arrays is driven by the inter-particle attractive interactions. The model is strongly supported by a series of carefully designed cluster deposition experiments.

2D metal oxide fractal structures with different appearance and composition are successfully grown on the silicon (100) substrates from their colloidal solutions at room temperature. These films display very high surface coverage on the substrates and abundant structures. The results demonstrate the appearances and dimensions of these structures are dependent on the properties and composition of their constituent particles and the substrates. This work may have potential applications in the fabrication of gas sensors, photon-receivers and catalyst carriers which are not easy made by other methods at RT.

General Rules

One of the main problems in the process of micro-machining for small and precision parts is that micro-burr will be generated. This paper carried out the two-dimensional numerical simulations with ABAQUS, which simulated the effects on burr formation coming from the micro-burr formation mechanism, tool geometry and cutting parameters in micro-machining process. The general rules of various factors impacting on burr formation were obtained in micro-machining process.
