Programmable Current Control of Silicon Field Emitter Arrays Using Gate-All-Around MOSFETs
Silicon field emitter array (FEA) technology has great potential for applications such as electron microscopy, vacuum electronics, and X-ray sources. However, some challenges such as emitter tip burnout and spatial and temporal non-uniformity of emission current impede the adoption of FEAs in these …

Modeling Light Duty Vehicle Emissions Based on Instantaneous Speed and Acceleration Levels
… for LDVs and LDTs. The model is found to be highly accurate compared to the ORNL data with coefficients of determination ranging from 0.92 to 0.99. The study compares fuel consumption and emission results from MOBILE5a, VT-Micro, and CMEM models. The dissertation presents that the proposed …

Parallel nano-manufacturing via electro-hydrodynamic jetting from externally-fed emitter arrays
… is unfeasible due to the low throughput and high cost of current production methods. The most common production process, known as electrospinning, involves pumping a viscous, conducting liquid at very low flow rates through a syringe needle in a strong electric field. The emitted charged jet …

Characterization of Thermophotovoltaics and Materials for High-Temperature Thermal Energy Storage
… TPVs have long had the potential to reach high efficiencies, but experimental demonstrations of devices have not met these predictions. Prior work has largely focused on ~0.5 – 0.75 eV devices paired with emitter temperatures <1300 °C. Operating at higher emitter temperature is advantageous …

Mesoscopic Fuel Consumption and Emission Modeling
… speed and acceleration level as it travels on a highway network. Alternatively, microscopic models capture these transient effects; however, the application of microscopic models may be costly and time consuming. Also, these tools may require a level of input data resolution that is not …
