"Three-dimensional textile reinforcement architectures with straight in-plane fibers and optimized through thickness fiber content are considered as efficient solutions for the next generation of light weight, damage tolerant, high strength compositesallowing for cost-effective manufacturing solutions. The 3-D weaving process is gentle to the fibers, thus making automated fiber optic sensor insert ...

"3TEX, Inc., the Center for Composite Materials at the University of Delaware, and the University of Rhode Island propose to further develop 3-D orthogonal woven composite materials for armor applications. We will use a combined approach of new materialsdevelopment, instrumented high strain rate and ballistic testing, and numerical impact simulation, to further phase 1 results on S-2 glass structu ...

"ASI's plasma consultant, Igor Alexeff, PhD, has invented, tested and patented an atmospheric pressure, dc of 60 Hz AC discharge, that has been operated in air, helium, argon and nitrogen. The apparatus has in laboratory testing successfully destroyedmicroorganisms. The apparatus does not require a complicated, fragile RF power supply for operation. We propose it to be developed into equipment for ...

"We propose to investigate the feasibility of using Avanti's self-aligning kinematic optoelectronic mounts for active 3-D RF/optoelectronic microstructures. We believe the unique benefit of our approach is the precision alignment of optoelectronic devicesfor coupling to the outside world (and layer-to-layer). This unique benefit is coupled with additional benefits of easy manufacturability, direct ...

"Laser beam interactions with free shear turbulent structures in the context of a recessed cavity window will be investigated. The proposed program will investigate the aero-optic degradation of a laser beam, housed within the cavity, and its remediationusing high frequency flow control. Beam wander and displacement statistics, obtained via a Position Sensitive Detector (PSD), will be complemented ...

"A product development effort aimed at constructing a novel magnetic resonance force microscope that is an exciting powerful new technology for detecting nuclear magnetic and electron-spin resonance of nanoscale samples and imaging subsurface features. Aprototype variable-temperature, variable-field instrument has been constructed at Cornell University and has already been used to detect both ele ...

"We propose to develop a new technique for imaging underground facilities based on the passive monitoring of acoustic emissions from both stationary and moving equipment within such facilities. It is well known that all mechanical devices, such as motors,gears, etc, emit acoustic signals. It is possible to identify an acoustic source based on its noise spectrum. In addition, by monitoring the acou ...

"It has been shown theoretically and experimentally, that one-dimensional photonic bandgap (1DPBG) structures enhance nonlinear effects for one to three orders of magnitude. By exploiting these effects, one can achieve efficient frequency conversion (secondand third harmonic generation, and parametric) in materials with modest nonlinear optical properties and in structures with a total path length ...

Dramatic differences in the diffusivities of the constituents of novel thin film materials and structures limit material perfection under far from equilibrium growth conditions. We will develop a new light-mass ion source, compatible with the low pressurerequirements of molecular beam epitaxy (MBE), to provide selective enhancement of the motion of surface atoms. Helium or hydrogen ions incident ...
