MICROSCALE [6 records]

Record 1 2014-04-04

English

Subject field(s)
  • Optics
CONT

Fundamental development of scanning thermal microscopy and application of the technique to microscale heat transport in a variety of electronic devices and interfaces is proposed. The goal is to obtain a spatial resolution of 1-10 nm and a temporal resolution of 10 ns in temperature measurement.

English

Subject field(s)
  • Mathematics, Physics and Natural Sciences
  • Electronics and Informatics
  • Medicine and Health
  • Industries
DEF

An array of nanosized objects, especially one of nanosized spots that have unusual optical characteristics.

CONT

By orienting and networking such wires, nano-circuitry can potentially be created, which may be of value in the computer industry. The nanostructures can also be incorporated into coatings with optical, electric, magnetic, catalytic, or enzymatic moieties as functional units. A nanoarray is a nanoscale or microscale ordered arrangement of nanotemplates and/or nanostructures. A nanoarray, therefore comprises an ordered array of nanostructures. A nanoarray can have any type of long range packing symmetry, including 2-, 3-, 4-, or 6-fold packing symmetry. The nanoarray can be a one-dimensional structure, a two-dimensional array, or a three-dimensional array. In a specific embodiment, where the nanoparticles are dielectrics, a three-dimensional nanoarray can be a photonic bandgap crystal. Optimal conditions for assembly and crystallization of a nanoarray... are easily determined by routine experimentation, such as by changing each variable individually and monitoring formation of the appropriate products.

CONT

We examine how synthetic dynamic nanostructured surfaces control the attachment of pathogenic biofilms. The parameters governing long-range patterning of bacteria on high-aspect-ratio (HAR) nanoarrays are combinatorially elucidated, and we discover that sufficiently low effective stiffness of these HAR arrays mechanoselectively inhibits ~40% of Pseudomonas aeruginosa biofilm attachment. Inspired by the active echinoderm skin, we design and fabricate externally actuated dynamic elastomer surfaces with active surface microtopography.

Record 5 1989-03-30

English

Subject field(s)
  • Environmental Studies and Analyses
  • Air Pollution
CONT

Microscale. Analysis of pollution dispersion on the microscale(< 1 km) is by its nature more specific to particular air pollution problems. Examples of these are emissions from vehicle traffic along highways, downwash around buildings, inner-urban pollutant effects, etc.... An important field in microscale APM studies is analysis of the mechanisms in pollutant deposition and fluxes to vegetation, water and soil.

English

Subject field(s)
  • Atmospheric Physics
  • Environmental Studies and Analyses
  • Air Pollution
CONT

Microscale phenomena have a characteristic length scale of no more than a few kilometers. Convection and aerodynamic separation are the chief causes of these situations which can lead to serious localized pollution problems.
