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 ...

In this STTR project we aim to build software interfaces and enhancements to existing parallel mesh adaptation libraries for applications in high performance flow modeling. In Phase-I we demonstrated a preliminary implementation of such a system and identified technology needs. Phase-II development will include both open source, as well as commercially supported mesh adaptation software and interf ...

Our objective is to significantly increase the electron transfer efficiency of the enzyme-catalyzed reactions at electrodes and thereby establish a new state-of-the-art power source for military and commercial systems. The approach is to develop a novel method for orienting enzymes immobilized onto the electrode surface that results in facilitated charge transfer. The proposed bio-electrode techn ...

Several laser types are in development by the government for advanced proximal sensors, including the quantum cascade laser, the miniature solid state laser with optical parametric oscillator and the miniature CO2 gas laser. The enabling critical component for all these advanced transmitters is the compact, robust, rapid, precision wavelength selector. It is proposed to develop and deliver a sta ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens' principle an ...

An innovative and fundamental approach to measure far field noise of a helicopter using a hot-air balloon as an acoustic measurement platform is described. The technique, featuring a microphone suspended beneath the basket of a hot-air balloon, is used to obtain acoustic data above, in, and below the horizon plane of a helicopter in forward flight. This approach is postulated to have many advantag ...

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 ...

We propose to develop a compact, integrated ion trap quantum system for quantum sensor, timekeeping, and computing applications. To do so, we leverage ColdQuantas expertise in miniature ultra-high vacuum (UHV) and atom chip technology and Duke Universitys expertise in microfabricated surface ion traps and quantum information processing experiments. We will produce a manufacturable, commercializa ...

In response to the Army STTR Topic A14A-T015 solicitation for tunable high-power LWIR lasers for standoff detection applications, Pranalytica proposed to develop a compact, rugged and highly reliable wavelength tunable quantum cascade laser (QCL) module delivering over 5W of peak power and over 0.5W of average power in the spectral region spanning from 7 to 11m. The proposed approach is based on a ...

Variational two-electron reduced-density-matrix (v2RDM) methods can provide a reference-independent description of the electronic structure of many-electron systems that naturally captures multireference correlation effects. These methods offer one of the few possible routes to performing the large-active-space computations that are necessary for the qualitative description of strongly-correlated ...
