Carbonate-Infused Activated Carbon for Direct Air Capture Sorbents
­Background Removal of carbon dioxide (CO2) from the atmosphere by direct air capture (DAC) can be accomplished using two chief approaches, liquid and solid. Liquid systems pass air through chemical solutions containing basic ions (e.g., hydroxide ions or bicarbonate ions), heat the resulting mixture to release the captured CO2, and then reuse the...

Self-Powered Global Positioning System (GPS)-Synchronized Micro-Continuous Point-on-Wave (CPoW) Module
­Background Electric power utilities have started using phasor measurement units (PMUs) to obtain time-synchronized measurements of the voltage and current magnitudes and phase angles, frequency, and rate-of-change frequency (RoCoF) throughout their systems. However, there are still several key measurements that PMUs are unable to provide. In particular,...

Efficient Depolymerization of Polyethylene-Based Plastics
­Background Discarded polyethylene-based plastics are not usually recycled because of their resistance to depolymerization due to stable carbon bonds. Pyrolysis is a quick thermochemical treatment technique that destroys plastic structures and turns them into fuels and chemical products. For the pyrolysis process, however, feedstock drying is required,...

Electrospun K2CO3/Activated-Carbon Composites for Carbon Dioxide Capture
­Background Direct air capture (DAC) is a process of capturing carbon dioxide (CO2) directly from air. The CO2 can be captured when the air contacts a chemical medium or functionalized sorbent, and then removed from the chemical medium or functionalized sorbent to yield a CO2 stream. Invention Description Researchers at Arizona State University...

Optimized Subspace-Based Approach to Synchrophasor Estimation
­Background Monitoring a power system involves not only measuring the fundamental 60 Hz signal, but additional harmonics (120 Hz, 180 Hz, 240 Hz, etc.) as well as clutter signals unassociated with any power frequency or harmonic. These clutter signals make it difficult to accurately estimate the magnitude, phase, and frequency of the fundamental...
