Scanning electron microscopy (SEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS) depth profiling were employed to characterize the aged zerovalent iron (AZVI) samples incubated in synthetic groundwater. The AZVI samples prepared under different conditions exhibited the passive layers of different morphologies, amounts, and constituents.(More)
In this paper, we propose a fully-functional Nanometer FPGA prototype chip. Compared to traditional single supply voltage, single threshold voltage design, we explore low power nanometer FPGA design challenges with Multi-Vt, Static Voltage Scaling and sleep mode technique. Compared to Dynamic Voltage Scaling (DVS), we make a table of Voltage-Delay parameter(More)
