Fabrication of high-aspect-ratio lightpipes

Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2011
The authors report the development of two fabrication processes for creating high-aspect-ratio lightpipes in a 10 μm thick SiO2 layer, with smooth, uniform, and straight vertical sidewalls. Both processes require only standard optical lithography, without the need for advanced electron beam or deep-UV lithography.

Screech characteristics of under-expanded high aspect ratio elliptic jet

, 2020
Screeching behavior and the closure mechanism of a feedback loop for the flapping mode in under-expanded supersonic jet are investigated by schlieren imaging and near-field acoustic measurements for a high aspect ratio elliptic nozzle.

High Aspect Ratio Carboxylated Cellulose Nanofibers Cross-linked to Robust Aerogels for Superabsorption-Flocculants: Paving Way from Nanoscale to Macroscale.

ACS Applied Materials and Interfaces, 2018
Charged nanocellulose (NC) with a high aspect ratio (larger than 100) extracted from animal or bacterial cellulose and chemical cross-linked NC aerogels have great promising applicability in material science, but facile fabrication of such NC aerogels ...

A review on the very high nanofiller-content nanocomposites: Their preparation methods and properties with high aspect ratio fillers

Progress in polymer science, 2018
For many years, the inorganic content in nanocomposites has seldom exceeded 10 vol%. Novel fabrication methods have been employed to incorporate high inorganic loading within the polymer matrix.

Aspect Ratio Influence at High Subsonic Speeds

Journal of the Aeronautical Sciences, 1956
The velocity induced by the thickness of a thin infinite wing in a parallel flow can be calculated, at some distance from the wing, by linearized subsonic compressible flow theory. If now, a portion of the infinite wing is removed from the flow, the velocity at any point on the wing will be less by the velocity induced by the portion of the wing which ...

Aeroacoustics of a High Aspect-Ratio Jet

9th AIAA/CEAS Aeroacoustics Conference and Exhibit, 2003
Circulation control wings are a type of pneumatic high-lift device that have been extensively researched as to their aerodynamic benefits. However, there has been little research into the possible airframe noise reduction benefits of a circulation control wing.

Flow-electrode capacitive deionization with highly enhanced salt removal performance utilizing high-aspect ratio functionalized carbon nanotubes.

Water Research, 2019
Flow-electrode-based capacitive deionization (FCDI) has attracted much attention owing to its continuous and scalable desalination process without the need for a discharging step, which is required in conventional fixed-electrode capacitive deionization.

High-Aspect-Ratio Structures for MEMS

MRS Bulletin, 2001
Many microelectromechanical systems (MEMS) use the changing capacitance of movable parallel plates to drive and sense motion. An increase in this capacitance improves the performance of these micromechanical structures by means of increased electromechanical coupling for lower driving voltages and increased sensitivity of the micromechanical motion.
