The long endurance “StratoSonde” lighter-than-air, uncrewed system combines a low-cost, 5day endurance StratoSonde supports up to 10 micro-dropsondes, which when released from the HAB, descend safely through the entire atmospheric column under a ribbon drogue while reporting observations directly back to the HAB. This project will assess the feasibility of integrating a disposable miniature ae ...

Under this STTR program, QuesTek Innovations LLC (QuesTek), teaming with Prof. Yip-Wah Chung at Northwestern University (NU), proposes to develop a nanocrystalline coating technology to enable consistent superlubricity in engines by combining computational materials design approach at QuesTek and experimental prototyping at NU, with consulting services provided by Prof. Christopher Schuh at Xtalic ...

This project focuses on the development of computational tools for the multiscale simulation of engineered wood products under impulsive loading conditions resulting from blasts and impacts. The proposed computational tools are based on a multiscale model for wood that simulates failure mechanisms at the length scale of the wood cellular structure. The adopted fine scale model, entitled Connectors ...

There is a clear need to improve weather forecasting accuracy. The greatest contributions to forecast uncertainty is a lack of meteorological observations over remote areas and areas experiencing pronounced convective activity. StratoSolutions’ new high-altitude balloon (HAB) platform with mini-dropsonde is a disruptive new uncrewed meteorological observation data source able to collect data at ...

As the single largest consumer of materials and energy use worldwide, the construction sector remains a prime target for materials reuse reform. (Krausmann et al., 2009; De Ia Rue du Can & Price, 2008). Construction and ongoing operation of the built environment extracts a significant amount of resources -- and on an ongoing basis. According to the U.S. Green Building Council (USGBC), buildings ac ...

We propose to develop a systematic approach to identify and design infrared-absorbing colloidal quantum dots for high-performance infrared imaging. This effort will enable the advancement of compact, lightweight, and low-cost infrared systems that are deployable with dispensable unmanned drones for surveillance in contested environments, vehicles in low-visibility conditions, and soldier-mountable ...
