Sandia evaluated design options for face coverings and face shields considering their effectiveness, durability, build difficulty, build cost, and comfort. More than 200,000 design combinations were evaluated for face coverings using Commonly Available Materials (CAMs) and more than 900 design combinations were evaluated for face shields using CAMs. Link: https://ip.sandia.gov/technology.do/techID=258 Image: Sandia

It is generally difficult to identify a specific substance in a solution, which contains high concentrations of other interfering substances, without getting a high rate of false positives. The invention in this patent helps in reducing this problem by using more than one signal to identify and detect a substance in the mixture (signals such as electrical, optical, acoustic etc). This reduces the errors in identification and could be useful… Read More »Sandia-Reducing false positives in detection techniques
The selective separation of biomolecules such as DNA and proteins through nanopores appears to be a promising technique for characterizing, counting, and sequencing these species. The patent describes a technique that can be used for this purpose, to separate proteins using a specific protein dependent electric field across a nanoporous polymer exclusion membrane. It states that at low electric fields, certain proteins do not pass through the membrane but at… Read More »Sandia-Separation of proteins by applying an electric field
Rapid detection of biological substances may be required in a number of applications like monitoring water supplies. This needs high sensitivity and high selectivity (i.e., low false-alarm rate) which can be costly and complex to design. This patent describes a technique for rapid real-time sensing of proteins in aqueous samples using direct absorption techniques.
