Fundamental Studies of Various Poly(L-lactide)/clay Nanocomposite Systems by in-situ Polymerization
… of organoclays for removal of Na+, silane edge treatment, and addition of a linking agent did not significantly improve molecular weight ofPILA-MMT.

Aerodynamics and aeroacoustics of flap side-edges
… aerodynamics and aeroacoustics of a flap side-edge. A porous side-edge treatment was applied to the flap side-edge in an attempt to reduce airframe noise. Measurements taken as part of the experimental study were forces, on-surface pressures, particle image velocimetry, hotwire anemometry and …

Analysis and design of planar slot antennas for RFID applications using characteristic mode theory
… from sub-resonant length antennas. In addition, edge treatment in the form of serrations can be used to improve the bandwidth and radiation properties of thin planar antennas. Although serrations offer a simple technique to improve radiation characteristics of a microstrip antenna, there are no …

Modifications of Coherent Structures in Fan Blade Wakes for Broadband Noise Reduction
The effects of trailing edge flow control on the wakes of a linear cascade of idealized fan blades was investigated experiments with a view to the likely effects on broadband aircraft engine interaction noise. Single and three-component hotwire velocity measurements were made downstream of the …

Small, dual band, placement insensitive antennas
… to the slot antenna. In this work, we show that edge serrations can reduce the cavity effect in a parallel plate configuration, making a slot antenna with edge treatments a viable design for environment-independent peel-and-stick applications. For this research to be broadly applicable, …
