Reentrainment of Submicron Solid Particles
… temperature on the short-term reentrainment of submicron particles. The particles tested are in the size range of 10-900 nm and are deposited by wetting the inside of capillary tubes with a liquid suspension. The tubes are then dried in a desiccator. The particles are reentrained under turbulent …

Submicron patterning using laser interference lithography
In this thesis, the theory, fabrication protocol, and initial results of an alternative nanopatterning technique called Interferometric Lithography (IL) are presented. Comprised of the identical process attributes of traditional projection photolithography, IL mirrors the wafer preparation and …

Rapid fabrication of deep-submicron Josephson junctions
A process was designed to fabricate Nb-AlOx-Nb Josephson junctions for quantum computing applications, with the goal of fabricating junctions as small as 0.2 [micro]m in diameter in a time span of roughly two weeks. The process was based on the doubly-planarized all-refractory technology for …

Submicron Correlations Of Receptor-positions On Cell Surfaces
Scanning fluorescence correlation spectroscopy (S-FOS) is introduced as a technique to measure the distribution of receptors on cell surfaces. The receptors are made observable by the binding of a specific ligand that is fluorescently labeled. This technique is based on fluctuation analysis through …

Optimal digital system design in deep submicron technology
The optimization of a digital system in deep submicron technology should be done with two basic principles: energy waste reduction and energy-delay tradeoff. Increased energy resources obtained through energy waste reduction are utilized through energy-delay tradeoffs. The previous practice of …

Negative magnetophoresis of submicron species in magnetic nanofluids
… work we studied the focusing and trapping of submicron, nonmagnetic species immersed in a magnetic nanofluid under applied magnetic fields. Focusing was achieved using two pairs of permanent magnets, which forced submicron fluorescently-tagged polystyrene beads to focus in the region between …

Stable submicron protein particles : formation, properties, and pulmonary applications
… process was not necessary to form the desired submicron protein particles. In SFL and TFF the surface area/volume ratio of the gas-liquid formed on the liquid protein formulations (46-600 cm⁻¹) was 1-2 orders of magnitude lower than in SFD (6000 cm⁻¹), leading to far less protein adsorption and …
