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...

Abstract:: Converting CO2 to valuable materials is attractive.Herein, we report using simple metallothermic reactions to reduce atmospheric CO2 to dense nanoporous graphene. By using a Zn/Mg mixture as a reductant, the resulted nanoporous graphene exhibits highly desirable properties: high specific surface area of 1900 m2/g, a great conductivity of 1050 S/m...

Creator:: Han, Katherine and Chang, Chih-Hung
Abstract:: 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, have...

The synthesis of cadmium sulfide nanoplatelets using a novel continuous flow sonochemical reactor

Creator:: Palanisamy, Barath, Paul, Brian, and Chang, Chih-hung
Abstract:: 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...

Ultrashort Near-Infrared Fiber-Optic Sensors for Carbon Dioxide Detection

Creator:: Chong, Xinyuan, Kim, Ki-Joong, Ohodnicki, Paul R., Li, Erwen, Chang, Chih-Hung, and Wang, Alan X.
Abstract:: In this paper, we report a fiber-optic carbon dioxide (CO₂) near-infrared (IR) absorption sensor with only 8-cm sensing length that is coated with nanoporous metalorganic framework material Cu-BTC (BTC = benzene-1,3, 5-tricarboxylate). The multimode optical fiber was etched by hydrofluoric acid to remove the cladding and part of the core,...

Printed Oxide Thin Film Transistors: A Mini Review

Creator:: Choi, Chang-Ho, Lin, Liang-Yu, Cheng, Chun-Cheng, and Chang, Chih-Hung
Abstract:: Compared to conventional amorphous silicon (a-Si) TFTs, amorphous metal oxide TFTs have superior device performance such as higher mobility, better sub-threshold swing, and lower off-state current. Amorphous metal oxide TFTs have an additional advantage on the device uniformity due to the lack of grain boundary issues in the poly-Si TFTs....

Aqueous Synthesis of Tailored ZnO Nanocrsytals, Nanocrystal Assembiles, and Nanostructured Films by Physical Means Enabled by a Continuous Flow Microreactor

Creator:: Choi, Chang-Ho and Chang, Chih-hung
Abstract:: 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...

Abstract:: Colloidal lead selenide nanoparticles (PbSe NPs) were synthesized using a microwave-assisted continuous flow reactor. Rapid heating of precursors was performed in the microwave reaction zone to initiate nucleation and was followed by an oil bath growth zone. In this study we have evaluated the effect of the nucleation temperature on...
