Self-neutralizing air-breathing thruster and method of neutralization
An ion-engine is the cutting edge for atmospheric air-breathing engines. The technology depends on ionizing and neutralizing atmospheric air particles which create thrust. This unique possibility makes it an ideal choice for very-low-orbit satellites. Very- low-orbit satellite capabilities have benefits such as higher resolution for images, weight...

Non-Invasive Plasma Discharge Tube Device for Treating Brain Tumors
Treating brain tumors, like glioblastoma, is challenging. Current glioblastoma drugs, Rapamycin and Temozolomide (TMZ), generally only extend life for a matter of months, are not very effective in treating recurring tumors, and have significant clinical toxicity. A novel Plasma Discharge Tube (PDT) device has the potential to be more effective and less...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Cold atmospheric plasma-stimulated media for treating cancers
For successful cancer therapy, the most important aspect is selective eradication of cancer cells without damaging healthy cells. Cancer cells and normal cells have different thresholds for tolerance of reactive oxygen species (ROS) and reactive nitrogen species (RNS) before cell death (apoptosis) is induced. Previously, GW researchers invented a cold...

Hydrothermal Crystal Growth that Eliminates Spontaneous Emission
This hydrothermal approach to growing single crystal oxide hosts resolves the issues posed by amplified spontaneous emission (ASE). ASE is the result of unwanted internal reflection of photons at the lasing frequency within the laser crystal. The consequences of ASE include induced emission of ions from the excited state and unwanted internal lasing...
