Abstract: Disclosed is a boiler may that uses recycled carbon dioxide as a working fluid. Instead of releasing high-purity CO2 into the atmosphere, the bulk of the CO2 is utilized as the working fluid and the produced CO2 is captured and sent to a pipeline for utilization or storage. These systems will minimize heat loss and achieve essentially zero CO2 emission to the air.

Abstract: Disclosed is an ethylene and/or propylene cracker unit that uses recycled carbon dioxide as a working fluid. A boiler may also use recycled carbon dioxide as a working fluid. In either instance, instead of releasing high-purity CO2 into the atmosphere, the bulk of the CO2 is utilized as the working fluid and the produced CO2 is captured and sent to the pipeline for utilization or storage. These systems will minimize heat loss and achieve essentially zero CO2 emission to the air.

Abstract: An alert apparatus and related systems. The alert apparatus includes a controller and a wireless receiver connected to the controller and configured to receive data from a transmitter. The alert apparatus includes a packaging containing the controller and receiver and a visual indicator connected to be controlled by the controller and visible from outside of a vehicle on which the alert apparatus is mounted. The visual indicator is controllably activated by the controller based on the received data, and the alert apparatus is mounted on a windshield of the vehicle.

Abstract: A nanocomposite material for use as an electromagnetic wave or radio frequency absorber or as a filter to trap or remove heavy metals. The nanocomposite material may be made with a one-pot synthesis, or thermodecomposition process, of magnetic graphene nanocomposites decorated with core-double-shell nanoparticles, wherein the double shell iron nanoparticles may comprise a crystalline iron core, an inner iron oxide layer around the crystalline iron core, and an outermost amorphous Si—S—O compound shell around the iron oxide layer.

Abstract: A driver alert apparatus and related systems. The driver alert apparatus includes a controller and a wireless receiver connected to the controller and configured to receive data from a transmitter, The driver alert apparatus includes an at least partially transparent packaging containing the controller and receiver. The driver alert apparatus includes a speaker and visual indicator connected to be controlled by the controller, such that the speaker and visual indicator are controllably activated by the controller based on the received data.
