Herein, 3D Array Technology LLC aims to develop a new type of nanostructure array (nanoarray) integrated microfibers to enable the medical masks with high filtration efficiency, low breathing resistance, and good antimicrobial capabilities. By integrating multifunctional nanoarray coatings onto the polypropylene microfibers through a scalable hydrothermal process, the surface area and roughness of ...

Early in the covid pandemic, decentralized and democratized AM of PPE was activated to alleviate supply chain failures that prevented normal suppliers of devices like face shields to meet the demands of the domestic health care system. Quality control testing, while critical to reducing risk by ensuring appropriate, safe, and reliable parts, is a time intensive and equipment intensive process. As ...

In this Phase 1 SBIR proposal, Vuronyx Technologies proposes to develop acetylperoxyborate (APB) powders for disinfection of Personal Protective Equipments (PPEs) so that they can be reused. APB powders are stable, active-oxygen containing compounds that release peracetic acid upon dissolution in water. As explained in this proposal, the use of a APB powder disinfectant has the following advantage ...

Filtering airborne infectious particles from indoor air is a critical element in controlling the spread of disease during COVID and future pandemics that are transmitted through the air. The aim of this proposed research from Ratiocinative Engineering Services, LLC is to develop a testbed that will lead to more accessible and robust quality control testing of air filtration and ventilation systems ...

Our biosensor is made of silicon nanowire arrays functionalized with antibodies to measure the concentration of specific proteins. In this grant we will take a sensor that has been demonstrated for use in measuring a set of generic host cell proteins and we will apply the sensor to measure a set of proteins for a specific cell line. In doing so, we will demonstrate the utility of our sensor to be ...

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 ...

Alphacore will develop an Intermediate Frequency (IF) Conversion System for High-Bandwidth Multiplexed Sensors Arrays for Phase II of NIST's 2018 soliciation for Exploratory Measurement Science Topic 9.04.02.68.The proposing team has already successfully developed and evaluated a prototype board in Phase I.The goal in Phase II is therefore to achieve three primary objectives:1) Optimize the design ...

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 ...

We will develop a series of object manipulation primitives to pick up and assemble standard mechanical parts such as screws, gears and pulleys that can be configured without any programming skills. Building up on a smart robotic gripper, 3D perception and machine learning algorithms, we will design a graphical user interface that allows an user to label arbitrary 3D objects, identify assembly poin ...

This SBIR Phase II project proposes to integrate an easy to use, inexpensive, and portable bacterial concentrator with a handheld pathogen detection system to enable ultra-low cholera pathogen (Vibrio cholerae) detection. Cholera affects communities across 41 countries, including in Yemen, where in the first 5 months of 2020 has had 110,000 suspected cases. Current methods used to detect the chole ...
