Absorption-based diamond spin microscopy on a plasmonic quantum metasurface
Nitrogen vacancy (NV) centers in diamond combine exceptional sensitivity with nanoscale spatial resolution by optically detected magnetic resonance (ODMR). Infrared (IR)-absorption-based readout of the NV singlet state transition can increase ODMR contrast and collection efficiency. Here, a resonant diamond metallodielectric metasurface amplifies IR absorption by concentrating the optical field near the diamond surface.

Combined electromagnetic and rate-equation modeling suggests a near-spin-projection-noise-limited sensitivity below 1 nT Hz−1/2 per μm2 of sensing area using numbers for contemporary NV diamond samples and fabrication techniques. The PQSM enables microscopic ODMR sensing with IR readout near the spin-projection-noise-limited sensitivity, making it appealing for imaging through scattering tissues and spatially resolved chemical NMR detection. |

Method to enhance solids and liquids flow through a stormwater containment volume
A method to enhance the ability of a stormwater containment volume to flow and flush solids and liquids. Implemented by depositing rock into shaped piles formed at the rock's angle of repose, the resultant inclined surfaces are covered with suitable waterproof material and covered with more rock up to the top surface. Stormwater flushes solids deposited on the surface downward into the volume where they contact the inclined surfaces. Water and solids flow down the inclined surfaces at increased velocity toward collection drainpipes at their base. Because sediment flows into drainpipes, it does not flow to the bottom of the volume or become stagnant or reduce the volume's capacity. This creates a low-cost stormwater containment system that can support vehicle travel on its surface, requires no concrete or sewers, is self-cleaning, accessible for cleaning, or both, and does not require human access to the bottom surface for maintenance. |
