From Rusting To Solar Power Plants: A Successful Nano-Pattering Of Stainless Steel 316l For Visible Light-Induced Photoelectrocatalytic Water Splitting, Heba H. Farrag, Alaa A. Abbas, Nageh Khalaf Allam

Faculty Journal Articles

A novel propitious nanoporous anodized stainless steel 316L (NASS316L) photoanode was developed for water splitting. The anodization could successfully produce a uniform nanoporous (- 90 nm in pore diameter) array (- 2.0 μm thick) of NASS316L with a high pore density. Several techniques, including FESEM, EDX, XRD, XPS, ICP-OES, and UV-vis-NIR spectrophotometry, were employed to characterize the catalyst and to assess and interpret its activity toward water splitting. Surprisingly, the NASS316L retained almost the same composition of the bare stainless steel 316L, which recommended a symmetric dealloying mechanism during anodization. It also possessed a narrow band gap energy (1.77 eV) …

Orbital Angular Momentum Generation Using Composite Quasi-Continuous Metasurfaces With Perfect Efficiency, Menglin L.N. Chen, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

A composite perfect electric conductor (PEC)-perfect magnetic conductor (PMC) metasurface is proposed for orbital angular momentum (OAM) generation. Each scatterer on the metasurface consists of an anisotropic PEC layer and an isotropic PMC layer. Unlike conventional metasurfaces that composed of discrete scatterers, the scatterers on the proposed metasurface form a quasi-continuous pattern. Therefore, negative consequences of periodicity breaking from the patterned scatterers with varying sizes or orientations and their mutual coupling are avoided. We model the scatterer using Jones matrix. Its design is based on the features of PEC and PMC, which abandons complicated optimization process. The patterning of scatterers …

Numerical Modeling Of Graphene Nano-Ribbon By Dgtd Taking Into Account The Spatial Dispersion Effects, Ping Li, L. (Lijun) J. Jiang, H. Baǧci

Electrical and Computer Engineering Faculty Research & Creative Works

It is well known that graphene demonstrates spatial dispersion properties [1]-[3], i.e., its conductivity is nonlocal and a function of spectral wave number (momentum operator) q. In this work, to fully account for effects of spatial dispersion on transmission of high-speed signals along graphene nanoribbon (GNR) interconnects, a discontinuous Galerkin time-domain (DGTD) algorithm is proposed. The atomically thick GNR is modeled using a nonlocal transparent surface impedance boundary condition (SIBC) [4] incorporated into the DGTD scheme. Since the conductivity is a complicated function of q (and one cannot find an analytical Fourier transform pair between q and spatial differential operators), …

Mechanical Engineering Faculty Publications

Hydrocarbons as reductants show promising results for replacing NH₃ in SCR technology. Therefore, considerable interest exists for developing low-temperature (< 200 °C) and environmentally friendly HC-SCR catalysts. Hence, C₂H₄ was examined as a reductant using activated-carbon-supported MnOx-based catalyst in low-temperature SCR operation. Its sensitivity to Mn concentration and operating temperature was parametrically studied, the results of which showed that the catalyst activity followed the order of 130 °C > 150 °C > 180 °C with an optimized Mn concentration near 3.0 wt.%. However, rapid deactivation of catalytic activity also occurred when using C₂H₄ as the reductant. The mechanism of deactivation was explored and is …
