Finite difference time domain modeling of subwavelength-structured anti-reflective coatings

Creator:: Han, Katherine, Han, Hai-Yue, Stack, James, Jr., and Chang, Chih-Hung
Abstract:: The finite difference time domain (FDTD) method was used to model anti-reflective properties of a variety of sub-wavelength structures for 300 to 1300 nm input light. Light hitting non-tapered nanostructures exhibited interference patterns similar to thin film anti-reflective coatings (ARCs), increasing the anti-reflective effect at several wavelengths. The lowest reflectance...

Oxide dispersion strengthened 304L stainless steel produced by ink jetting and laser powder bed fusion

Creator:: Paul, Brian K., Lee, Kijoon, He, Yujuan, Ghayoor, Milad, Chang, Chih-hung, and Pasebani, Somayeh
Abstract:: This paper discusses the fundamentals of a novel hybrid method to synthesize oxide dispersion strengthened (ODS) 304 L stainless steel (SS) alloy using a modified laser powder bed fusion (LPBF) machine. Previously, ODS metal matrix composites have been produced by LPBF via ball-milling, which is expensive to scale. Here, we selectively...

Selective laser melting of austenitic oxide dispersion strengthened steel: Processing, microstructural evolution and strengthening mechanisms

Creator:: Ghayoor, Milad, Lee, Kijoon, He, Yujuan, Chang, Chih-hung, Paul, Brian K., and Pasebani, Somayeh
Abstract:: Oxide dispersion strengthened (ODS) alloys exhibit superior mechanical properties due to the presence of nano-sized thermally stable oxide particles. However, manufacturing of ODS alloys is very complex and composed of numerous time consuming steps such as mechanical alloying, which is one of the main barriers toward the widespread application of...

Selective laser melting of 304L stainless steel: Role of volumetric energy density on the microstructure, texture and mechanical properties

Creator:: Ghayoor, Milad, Lee, Kijoon, He, Yujuan, Chang, Chih-hung, Paul, Brian K., and Pasebani, Somayeh
Abstract:: The role of volumetric energy density on the microstructural evolution, texture and mechanical properties of 304L stainless steel parts additively manufactured via selective laser melting process is investigated. 304L is chosen because it is a potential candidate to be used as a matrix in a metal matrix composite with nanoparticles...

A Feasibility Analysis of Implementing the Closed Fishing Seasons on the North-east Coastal Fisheries in Taiwan -- An Application of Fisheries Co-management

Creator:: Hao-Ting, Liu, Chuang, C. T., Lee, Y. H., and Chang, C. W.
Abstract:: The status of fisheries resources on coastal and offshore areas is getting worse in Taiwan. Thus, to establish a fishery resources management system has become the main task among stakeholders. In this study, we would like to examine the feasibility of imposing the community-based co-management system and setting closed fishing...

Nonlinear Photocarrier Dynamics in Multilayer WSe2 Induced by Intense Terahertz Pulses

Creator:: Guay, Viela, Johnson, Nathan, Zhang, Yue, Van Der Zande, Arend M., Thorp, Spencer G., Graham, Matthew, and Lee, Yun-Shik
Abstract:: Non-equilibrium photocarriers in multilayer WSe2 injected by femtosecond laser pulses exhibit extraordinary nonlinear dynamics in the presence of intense THz fields. The THz absorption in optically excited WSe2 rises rapidly in the low THz field regime and gradually ramp up at high intensities. The strong THz pulses drive the photocarriers...

High-field terahertz response of graphene

Creator:: Paul, M. J., Chang, Y. C., Thompson, Z. J., Stickel, A., Wardini, J., Choi, H., Minot, E. D., Norris, T. B., and Lee, Yun-Shik
Abstract:: We investigate the response of multi-layer epitaxial graphene and chemical vapor deposition (CVD)-grown single-layer graphene to strong terahertz (THz) fields. Contrary to theoretical predictions of strong nonlinear response, the transmitted fields exhibit no harmonic generation, indicating that the nonlinear response is limited by fast electron thermalization due to carrier-carrier scattering....

Abstract:: The isotopic composition of water vapour provides integrated perspectives on the hydrological histories of air masses and has been widely used for tracing physical processes in hydrological and climatic studies. Over the last two decades, the infrared laser spectroscopy technique has been used to measure the isotopic composition of water...

K. P., Zaneveld, R., and Zappa, C. J.
Abstract:: Optical variability occurs in the near-surface and upper ocean on very short time and space scales (e.g., milliseconds and millimeters and less) as well as greater scales. This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and...

Abstract:: Internal gravity waves, the subsurface analogue of the familiar surface gravity waves that break on beaches, are ubiquitous in the ocean. Because of their strong vertical and horizontal currents, and the turbulent mixing caused by their breaking, they affect a panoply of ocean processes, such as the supply of nutrients...
