Based on success in the Phase I development of achromatic lens technologies to reduce the space and weight of optical systems, Physical Optics Corporation (POC) proposes to continue the development of a Single Element Achromatic Lens (SEAL) technology. The SEAL comprises a monolayer dielectric nano-antenna array, which is thin (

The theoretical energy and power of supercapacitors is determined by their capacitance, working voltage window, and conductivities of electrode materials/electrolytes as a function of temperature. With recent advances in nanomaterials-based electrodes, the performance of supercapacitors is mainly limited by the electrolytes. Current supercapacitors use flammable organic electrolytes that are un-sa ...

This project will provide state-of-the-art predictive capabilities for simulating systems central to advancing the U.S. Army’s modernization priorities related to long-range precision fires and future vertical lift platforms. The goals of the project are to: (1) Produce geometry and meshing technologies that support the modeling and discretization techniques needed to explicitly track evolving/i ...

In this Small Business Innovative Research (SBIR) effort, Nikira Labs Inc. proposes to develop a compact Raman fiber optic probe with inline spectral filtering that improves fiber-coupled Raman measurements by filtering out Raman scattering from the excitation fiber and elastically scattered laser light from the collection fibers. The technology will enable compact fiber probes for Raman studies i ...

Phase I has proven that the current setup achieves better than 8mm spatial resolution for 2.2MeV prompt gammas. However, 1mm spatial resolution presents a significant challenge for the current setup due in part to limited timing resolution and count rate. A new analog ASIC will be developed to replace the current analog ASIC that will have better timing resolution and deliver higher count rates. I ...

This project will develop a new scientific instrument optimized for the advanced characterization of near-infrared fluorescent nanoparticles that can exist as left- or right-handed structures (enantiomers). Single-walled carbon nanotubes (SWCNTs) are the leading current example of such nanomaterials. Applied NanoFluorescence, LLC (ANF) proposes a novel multi-mode chiroptical spectrometer that can ...

The variational two-electron reduced-density matrix (v2RDM) method provides an effective framework for computer modeling of the electronic structure of complex molecules and materials that exhibit strong correlation effects. In Phase I and Phase II of this STTR we have demonstrated that the GPU-accelerated implementation of the v2RDM-based complete active space self-consistent field (v2RDM-CASSCF) ...

Fullmoon has the first chip-level sensors capable of identifying and quantifying molecules in the air. At the core of our technology are printed voltammetric sensors, which are operated using cyclic voltammetry, an electrochemical technique that probes for the redox potential, a unique signature of molecules. We have demonstrated this sensing principle for the detection of carbon monoxide and meth ...

Modern Model-Based Enterprise / Engineering (MBE) systems rely on freeform surfaces built as complex combinations of geometric primitives to define engineered objects. Unfortunately, the intersection of freeform surfaces in MBE applications results in highly approximated solutions, degrading models that cost billions annually by US industry to fix. Current technology limits the abilities of users ...

Industrial facilities, manufacturing plants, and electric power plants that burn fossil fuels exhaust the combustion products to atmosphere through their smokestacks. Stack pollutant emissions are quantified using manual testing methods developed in the 1960s, which are prone to error if non-axial flow exists in a stack.Recently, NIST has been working on an improved technique of performing 3D flow ...
