Nanoscale zerovalent iron (NZVI) was evaluated for the reduction of bromate that is a highly persistent and carcinogenic oxyhalid formed as an ozonation byproduct during oxidative disinfection in drinking water treatment. Solid-phase NZVI with different surface areas controllably synthesized using liquid phase reduction. Transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer−Emmett−Teller (BET) area porosity analyzer were utilized to characterize particle size, morphology,...
In this paper, we present a new passive control device for form-drag reduction in flow over two-dimensional bluff body with blunt trailing edge. The consists of small tabs attached to the upper and lower edges effectively perturb wake. Both wind-tunnel experiment large-eddy simulation are carried out examine its drag-reduction performance. Extensive parametric studies performed experimentally by varying height width tab spanwise spacing between adjacent at three Reynolds numbers 4200...
This article presents a 36-channel scanning light detection and ranging (LiDAR) sensor with an on-chip single-photon avalanche diode array. The has area-efficient 11-bit in situ histogramming time-to-digital converter 3000 ×78 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> per channel area based on mixed-signal accumulator, though it is incorporated filtering capabilities. Furthermore, owing to its embedded interference (IF) filter,...
To use nuclear energy sustainably, spent fuel, classified as high-level radioactive waste and inevitably discharged after electricity generation by power plants, must be managed safely isolated from the human environment. In Korea, land area is limited amount of waste, including fuels to disposed, relatively large. Thus, it particularly necessary maximize disposal efficiency. this study, a high-efficiency deep geological repository concept was developed enhance end, design strategies...
This paper proposes a novel approach to adding and editing clothing movement of 4D volumetric video data in web-based environment. While significant advancements have been made 3D modeling animation, efficiently mesh produced sequence remains challenging problem. Since synthesized from multiple cameras exists continuously over time, modifying single model requires consistent across frames. Most existing methods focus on meshes or static models, limiting their ability handle the complexity...
This paper introduces spherical and ellipsoidal metamaterial lenses designed based on the Luneburg lens transformation optics for underwater ultrasound imaging, which enhances signals over a broadband frequency range detects objects at wide-angle. The meta-atoms were analyzed with dispersion curves, equi-frequency contours, effective acoustic parameters to design predict focusing performance. three-dimensional made of stainless steel demonstrated numerically experimentally in an environment...
This paper presents a 36-channel scanning light detection and ranging (LiDAR) sensor with an on-chip single-photon avalanche diode (SPAD) array.

When fluid particles such as bubbles and droplets are not in contact with the wall, one probably neglects wall drag term one-dimensional momentum equation for dispersed phase. This treatment however leads to an unphysical prediction of motion In framework conventional two-fluid model, how apply phase is disputable. The interface force acting on a particle results from interaction between surrounding continuous fluid. To clarify contributions forces phase, volume-averaged equations formulated...
