Magnetic two-way valves for paper based microfluidics: pathway for multi-step assays
Summary: ISU researchers developed a paper-fluidic valve that can reversibly switch fluid delivery into multiple channels with controlled volume and/or frequency. In terms of electric circuit equivalence, this valve is akin to a transistor or an SPDT relay, hence enables programmable fluid delivery. Stage1.png Development Stage: Description: Poin...

Point heating-probing method for thermal conductivity measurement of bulk and film-like materials
Summary: Iowa State University researchers have developed a novel point heating-probing device and method for measurement of thermal conductivity of bulks and film-like materials. This steady-state method uses a continuous laser to heat one tiny point on the bulk, and then measure another point for temperature drop to determine materials’ the...

Machine for Computing Casual Inference from Time Series Data
Summary: Iowa State University researchers have developed a novel algorithm approach for computing causal interaction from time series data. The proposed approach will help determine which time series data will cause or influence which other time series data, given two or more-time series data. Stage1.png Development Stage: Description: The dete...

Logarithmic Photo-Converter with Huge Dynamic Range
Summary: This device is capable of measuring optical light levels that may vary from the single photon level up to many orders of magnitude larger illuminations. In fact, the upper range can be almost, apart from practical spatial details, as large as one desires. This device is possible due to the fact that the SiPMs can be exposed to daylight at ...
