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,...

Near-infrared absorption gas sensing with metal-organic framework on optical fibers

Creator:: Chong, Xinyuan, Kim, Ki-Joong, Li, Erwen, Zhang, Yujing, Ohodnicki, Paul R., Chang, Chih-Hung, and Wang, Alan X.
Abstract:: Despite significant advantages in terms of portability and cost, near-infrared (NIR) gas sensing still remains a great challenge due to its relatively weak overtone absorption from the fundamental vibrational bond absorption at the mid-IR frequency. In this paper, we demonstrated ultra-sensitive NIR gas sensing for carbon dioxide (CO₂) at 1.57...

Creator:: Su, Yu-Wei, Ramprasad, Sudhir, Han, Seung Yeol, Wang, Wei, Ryu, Si Ok, Palo, Daniel R., Paul, Brian K., and Chang, Chih-hung
Abstract:: Continuous microreactor-assisted solution deposition is demonstrated for the deposition of CdS thin films on fluorine-doped tin oxide (FTO) coated glass. The continuous flow system consists of a microscale T-junction micromixer with the co-axial water circulation heat exchanger to control the reacting chemical flux and optimize the heterogeneous surface reaction. Dense,...

Creator:: Kim, Ki-Joong, Chong, Xinyuan, Kreider, Peter B., Ma, Guoheng, Ohodnicki, Paul R., Baltrus, John P., Wang, Alan X., and Chang, Chih-Hung
Abstract:: Combined plasmonic nanocrystals and metal–organic framework thin-films are fabricated for sensing gases in the near-infrared range. This nanocomposite thin-film shows a highly sensitive response in near-infrared absorption, which is attributed to preconcentration of gas molecules in metal–organic framework pores causing close proximity to the electromagnetic fields at the plasmonic nanocrystal...

Visible-light-sensitive nanoscale Au-ZnO photocatalysts

Creator:: Kim, Ki-Joong, Kreider, Peter B., Chang, Chih-Hung, Park, Chul-Min, and Ahn, Ho-Geun
Abstract:: The role of gold nanoparticles supported on ZnO in photocatalytic activity for dye degradation was investigated. To do this, gold nanoparticles supported on ZnO (Au-ZnO) were prepared using a simple co-precipitation method. The prepared nanocatalyst was characterized by high resolution transmission electron microscopy, X-ray diffraction, temperature programmed reduction, X-ray photoelectron...

Abstract:: The thermal oxidation of submicron metallic Zn particles was studied as a method to form nanostructured ZnO films. The particles used for this work were characterized by electron microscopy, x ray diffraction, and thermal analysis to evaluate the Zn-ZnO core shell structure, surface morphology, and oxidation characteristics. Significant nanostructural changes...

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...

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....
