SixPoint Materials will create low-cost, high-quality vertical gallium nitride (GaN) substrates using a multi-phase production approach that employs both hydride vapor phase epitaxy (HVPE) technology and ammonothermal growth techniques to lower costs and maintain crystal quality. Substrates are thin wafers of semiconducting material needed for power devices. In its two-phase project, SixPoint Mate ...

Organic chemicals comprise the dominant fraction of particulates found in atmospheric aerosols, and the largest proportions of these are secondary products formed in the atmosphere from oxidation of volatile organic compounds. Often these chemical transformations result from complex pathways involving species from different sources. To understand these processes, we need to be able to trace the ...

NanoSD, Inc. with its partners will develop a transparent, nanostructured thermally insulating film that can be applied to existing single-pane windows to reduce heat loss. To produce the nanostructured film, the team will create hollow ceramic or polymer nanobubbles and consolidate them into a dense lattice structure using heat and compression. Because it is mostly air, the resulting nanobubble s ...

Neutron Scattering has been an extremely productive materials science probe for over 60 years. It is no exaggeration to say that any technology that uses plastics has benefitted from it in some way from Small Angle Neutron Scattering (SANS). Unfortunately, SANS is limited to studying molecular structures with sizes between 1 to 100 nm and so often misses larger details. Similarly, neutron radiogra ...

Density functional theory is used by many researchers funded by the Department of Energy as a method for predicting the behavior of chemicals and materials used in energy applications. However, results of these calculations are often not standardized and, even when they are, expert-level understand of the methods is needed in order to properly perform a simulation. The energy research community a ...

Existing high quantum efficiency (QE) photocathodes experience very short lifetimes, often only a few hours. Because of the fabrication expense for these cathodes, commercial use is impractical for most applications. Photocathodes with long lifetime are needed to make photoguns cost effective for commercial applications. CCR and the University of Maryland are applying controlled porosity reservoir ...

Metrology is a multi-billion dollar industry that is an indispensable part of science and manufacturing. A variety of techniques including interferometric microscopes, scanning electron microscopes (SEM), X-ray, and atomic force microscopes (AFM) are used in X-ray mirror manufacturing. The performance of any tool directly depends on the ability to characterize and tune it ...

This project is about development of novel multilayer dielectric capacitors via thermal spray coating route. Use of this technology will enable mass production of multilayer ceramic capacitors at lower cost.

A key requirement for microalgae biofuels production is a very low cost harvesting technology. Commercially available solidliquid separation technologies applicable to microalgae, such as chemical coagulation, membrane separations and centrifugation, are too costly for biofuels production or other lowcost microalgae processes, such as wastewater treatment. A low cost harvesting process is bio floc ...

The problem/situation that is being addressed is the development and improvement of compact laser- driven x-ray sources for ultrafast characterization of interest to the DoE. While much progress has been made in the development of table-top x-ray sources, with high harmonic sources and atomic soft x-ray lasers presently allowing for a large number of experiments to be conducted in small laborator ...
