 | The open sea is an area in which numerous legal activities occur, such as trade, transportation, and scientific research, but it also is a place that attracts persons with illegal, criminal, and terrorist intentions. Naval nations, often acting in alliance, conduct operations to stop this illegal activity. Maritime interdiction operations (MIO) are the usual type of operation employed, and, because of their nature, they require robust communications and an uninterrupted ... |

|
| A small, lightweight microdevice has been developed for activity-dependent stimulation (ADS) and successfully tested for functionality in both anesthetized and ambulatory rats. Further, in semi-chronic experiments in rats with TBI using this microsystem, an unprecedented, potent effect of ADS on motor performance has been demonstrated, as compared to control rats (injured but no microdevice) and open-loop stimulation (OLS) rats. Specifically, open-loop stimulation does result in some recovery after injury, but ... |

| A new methodology to parallelize the production of micromechanical test samples from bulk materials is reported. This methodology has been developed to produce samples with typical gage dimensions on the order of 20 to 200 microns, and also to reduce the unit-cost-per-sample compared to conventional focused ion beam (FIB) fabrication methods. The fabrication technique uses standard microelectronic process methods such as photolithography and deep-reactive ion etching (DRIE) to create high ... |

| Memristive nanoelectronic devices share many of the properties of resistors, as well as the same unit of measure (ohm). However, in contrast to ordinary resistors in which the unit of resistance is permanently fixed, memristance may be programmed or switched to different states based on the history of the voltage applied to the memristance nanomaterial. This project was a unique collaboration between researchers at the College of Nanoscale Science & ... |

| EUV lithography, using 13.5-nm light, is considered to be the preferred technology for next generation microelectronic circuit fabrication. The introduction of EUV Lithography was delayed already several times and is in danger to be delayed again due to the lack of a high enough power light source allowing for volume production.

| High performance polyimides are currently utilized in a number of aerospace and microelectronic applications. Due to the inherent electronic polarity of the monomers used to synthesize many of these materials, resultant polymers often suffer from property degradation due to exposure to humid conditions, especially at elevated temperatures, often compromising their capabilities in service. The use of monomers demonstrating reduced susceptibility to hydrogen bonding with water molecules without sacrificing mechanical properties ... |

| The pulsed laser has been a popular experimental method for interrogating single event effects (SEEs) in microelectronic devices and circuits for many years [1]. While particle accelerator testing is still considered to be the standard test method, the expense and availability of particle accelerator facilities suitable for SEE testing can often be limiting factors in thoroughly characterizing devices and circuits. Particle accelerator testing can also be destructive since devices can ... |

| Multilayer cantilever structures are widely applied in micro/nanosystems. Unfortunately, the manufacturability/planarity/reliability has been always inadequate. While much of the understanding regarding the thermomechanical behavior of layered systems derives from experiences in microelectronics, significant differences exist for many micro/nanosystem applications, and these must be well understood to optimize the design of reliable MEMS/NEMS. The overall objectives of this work is to contribute to the scientific understanding of micro- and nano- mechanics ... |

| This is one of three reports on the study of micro-robots. This document describes the development of novel highly mobile small robots called "Mini-Whegs" that can run and jump. They are derived from our larger Whegs series of robots, which benefit from abstracted cockroach locomotion principles. Key to their success are the three-spoke appendages, called wheel-legs, which combine the speed and simplicity of wheels with the climbing mobility of legs. ... |
