Currently, the most promising types of radiotherapy is proton or carbon therapy, as they have demonstrated significant improvements in clinical efficiency and reduced toxicity profiles. Unfortunately, the high cost of treatments using both proton and carbon beams is the limiting factor preventing hadron therapy from becoming the standard of care for a wider range of cancers. Designing a linear acc ...

The power output of the high power lasers used in physics research is limited by the materials available for making the gain media in the laser. Future increases in power will require new and better materials. Operation at high power creates great thermal stresses that can lead to effects such as birefringence, thermal lensing or even physical fracture damage to the host itself. Effective cooling ...

There is a continuing need for high power circulators to protect the next generation of high power RF sources from waveguide reflections that can destroy the device. Currently, the power level of circulators is limited by the materials, specifically ferrites that provide the required non-reciprocal operation. New approaches are required that use materials capable of very high power operation. Stat ...

Modern quantum information systems employ optical photons for long distance communication, operating at ambient temperature, between microwave cavities, which house microwave photons used in quantum computing and microwave detection. These optical photons, carried by fiber-optic or free-space links, offer a low-cost, uncooled alternative to bulky, expensive microwave coaxial cables, which are loss ...

Sn-doped In2O3 (ITO) is the industry standard and most widely used transparent conducting electrode (TCE) because of its good electrical and optical properties. However, ITO has a number of disadvantages: ITO is not a suitable TCE for next-generation, high-efficiency, flexible OLEDs, because of its inappropriate work function, difficulty in creating desired patterns, low stability, delaminantion d ...

Near-field scanning optical microscopy (NSOM) is a powerful and unique approach to characterize the chemical, physical and potentially biochemical properties of materials with the nanometer scale resolution in real-time. A key element for NSOM systems that combine optical spectroscopy with scanning probe microscopy, is the actual probe itself. While many commercial vendors offer off-the-shelf meta ...

Currently the chemical composition of atmospheric particulate matter is measured either by off-line analyses of time-integrated filter samples, or by in-situ instruments requiring near-constant operator oversight. These measurement approaches result in sparse or limited data coverage. Despite the critical role of composition on the health and environmental impacts of particulate matter, there exis ...

Renewable sources of energy including solar and wind are fast gaining ground on fossil fuels, in part because of their sustainability and environmental benefits. A major issue, however, has been finding efficient ways to store the energy that renewables generate for use when the demand for energy is high. Lithium-­‐sulfur batteries, which store electrical energy by transferring electrons to or ...

This Phase II Small Business Innovation Research project targets the development of a technology for segregating fuelbased contaminants (char and ash) from oxygen carrier material in the context of chemical looping combustion application. In chemical looping, the wellmixed solids that flow from the fuel reactor consisting of char, ash, and oxygen carrier particles cannot be completely separated in ...

Reactive absorption-based carbon dioxide capture processes using solvents is the preferred technology for large scale capture of carbon dioxide in flue gases from coal-fired power plants. This Small Business Innovation Research project targets the development of mitigation strategies to decrease the quantity of aerosols that are formed from such post-combustion capture systems in the presence of s ...
