The objective of this program is to develop flexible, high-efficiency perovskite photovoltaic modules for incorporation onto future fabric-based Army packs, tents and shelters, as well as UAVs, drones and other platforms, to provide portable, renewable electrical power and reduce the need for warfighters to carry multiple heavy batteries. During Phase I, NanoSonic and Penn State analyzed approache ...

Scanning probe microscopy (SPM) is a technique used to detect near-field interaction when a sample is rater-scanned by a probe. Example include atomic force microscope (AFM) and scanning tunneling microscope (STM). It offers nanometric and atomic image resolution. In this field, an emerging technique, Near-Field Scanning Microwave Microscopy (SMM), utilizes microwave evanescent waves to attain the ...

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 ...

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 ...

Ballistic systems operate in flow regimes characterized by high speeds, temperatures and pressures, with reacting multiphase, multi-species fluids and fluid-structure interactions. Substantial progress has been made on methods to simulate the component physics. However, there are technical gaps remaining related to tracking the interacting physical components throughout a simulation. This project ...

Swabs are routinely used by crime scene investigators and forensic scientists for the collection of a wide range of biological evidence for analysis. Sterile cotton swabs are popular with forensic investigators due to their proficiency in adsorbing cellular material, however they are known for their low efficiency of sample (DNA) release. To better meet the needs of forensic investigators, Luna I ...

Despite their broad applications, up to date, diode pumped solid state green lasers are almost exclusively dominate the market due to the lack of low defect or defect-free semiconductor materials with high efficiency at green wavelength (480-550nm). We propose to develop compact, high efficiency, and high brightness III-nitride based green lasers. In phase I, we will focus on design, epitaxial gro ...

Next Dimension Technologies and Caltech will jointly develop a handheld detector to meet the Armys need for a field-based illicit drug identification system. The project will focus on the design and development of a dual-mode chemiresistive sensor array capable of detecting key drugs of interest, including synthetic cannabinoids and opioids. Novel sensing materials, with enhanced chemical sensit ...

This Phase I STTR project will develop a platform to demonstrate high-quality, multi-modal acquisition of neurophysiological signals, including EEG, heart rate/blood oxygenation via photoplethysmography (PPG), electrodermal (EDA) activity, temperature plus environmental factors such as ambient light and sound in a simple, wearable headband. The hardware will be coupled with the development of a cl ...

Using advanced ion optics that was developed by Pacific Northwest National Laboratory (PNNL), BaySpec will develop a prototype of portable mass spectrometer (less than 40 lb. and 300W) with continuous atmospheric pressure inlet that is fully capable of uninterrupted on-line sampling from an ambient environment. The continuous nature of the inlet ensures full compatibility with separation technique ...
