This paper reviews the current progress in mathematical modeling of
anti-reflective subwavelength structures. Methods covered include effective medium
theory (EMT), finite-difference time-domain (FDTD), transfer matrix method (TMM), the
Fourier modal method (FMM)/rigorous coupled-wave analysis (RCWA) and the finite
element method (FEM). Time-based solutions to Maxwell’s equations, such as FDTD,

ZnO nanofilms with four distinctly different morphologies were fabricated by adjusting physical parameters including the flow rate of the solution and rpm of the rotating disk in the continuous flow mircroreactor system while keeping the same chemical precursors, precursor solution concentration, and reaction temperature. Controlled reactive species including colloidal ZnO...
A continuous flow sonochemical reactor was developed capable of producing metastable cadmium sulfide (CdS) nanoplatelets with thicknesses at or below 10 nm. The continuous flow sonochemical reactor included the passive in-line micromixing of reagents prior to sonochemical reaction. Synthesis results were compared with those from reactors involving batch conventional heating...
Copper sulfides (CuxS) are compound semiconductor materials that exhibit considerable variations of optical and electrical properties. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding coatings. In this paper, chemical bath deposition...
Sintering of nanoparticle inks over large area-substrates is a key enabler for scalable fabrication of patterned and continuous films, with multiple emerging applications. The high speed and ambient condition operation of photonic sintering has elicited significant interest for this purpose. In this work, we experimentally characterize the temperature evolution and...

Assembly of nanocrystals is considered one of the most promising approaches to design nano-, microstructures, and complex mesoscopic architectures. A variety of strategies to induce nanocrystal assembly have been reported, including directed assembly methods that apply external forces to fabricate assembled structures. In this study ZnO nanocrystals were synthesized in...
