A monitoring case study of the hydrologic performance of the Aquaflow infiltrating road foundation. The results show a good performance in peak delay of 4 - 8 hours, volume retention of 50% to 97% and peak reduction of 15% to 76% for varying rainfall events and initial soil conditions. The results are promising for future implementation to obtain more sustainable urban drainage systems in Rotterdam. ... Read more

Quantum computing's value proposition of an exponential speedup in computing power for certain applications has propelled a vast array of research across the globe. While several different physical implementations of device level qubits are being investigated, semiconductor spin qubits have many similarities to scaled transistors. In this article, we discuss the device/integration of full 300mm based spin qubit devices. This includes the development of (i) a ²⁸ Si epitaxial module ecosystem for growing isotopically pure substrates with among the best Hall mobility at these oxide thicknesses, (ii) a custom 300mm qubit testchip and integration/device line, and (iii) a novel dual nested gate integration process for creating quantum dots. ...
