TantaluTantalum disulfide is gathering considerable attention due to its rich phase diagram that includes polytypes and charge density wave, thus having the potential for electrical device applications. However, epitaxial TaS2 thin films grown by chemical vapour deposition are still limited due to few available precursors. Herein, an originally designed atmospheric chemical vapour deposition with a separate-flow system was proposed to accomplish the controlled synthesis of TaS2 thin films. The sophisticated deposition sequence enables us to make unidirectional TaS2 triangle domains on c-plane sapphire using a chloride precursor. The quality of the grown TaS2 thin films was confirmed by X-ray diffraction, Raman spectroscopy, transmission electron microscopy and observing a step-and-terrace structure without spiral defects. The growth mechanism was discussed and concluded as the Volmer-Weber mode from the surface morphologies and elemental analysis. Our strategy is expandable to the other transition metal dichalcogenides because all the chloride precursors show a considerable vapour pressure below 200 °C.

Inactivation Characteristics of a 280-nm Deep-UV Irradiation Dose on Aerosolized SARS-CoV-2

Research paper (journal)
A non-filter virus inactivation unit was developed that can control the irradiation dose of aerosolized viruses by controlling the lighting pattern of a 280 nm deep-UV (DUV)-LED and the air flowrate. In this study, the inactivation properties of aerosolized SARS-CoV-2 were quantitatively evaluated by controlling the irradiation dose to the virus inside the inactivation unit. The RNA concentration of SARS-CoV-2 remained constant when the total irradiation dose of DUV irradiation to the virus exceeded 16.5 mJ/cm2. This observation suggests that RNA damage may occur in regions below the detection threshold of RT-qPCR assay. However, when the total irradiation dose was less than 16.5 mJ/cm2, the RNA concentration monotonically increased with a decreasing LED irradiation dose. However, the nucleocapsid protein concentration of SARS-CoV-2 was not predominantly dependent on the LED irradiation dose. The plaque assay showed that 99.16% of the virus was inactivated at 8.1 mJ/cm2 of irradiation, and no virus was detected at 12.2 mJ/cm2 of irradiation, resulting in a 99.89% virus inactivation rate. Thus, an irradiation dose of 23% of the maximal irradiation capacity of the virus inactivation unit can activate more than 99% of SARS-CoV-2. These findings are expected to enhance versatility in various applications. The downsizing achieved in our study renders the technology apt for installation in narrow spaces, while the enhanced flowrates establish its viability for implementation in larger facilities.

Effect of the Large-Scale Structure on Turbulent Prandtl Number in a Turbulent Shear Layer

Proceedings of ASME-JSME-KSME 2019 8th Joint Fluids Engineering Conference ( AMER SOC MECHANICAL ENGINEERS ) AJKFluids2019-4722 - V001T01A060 (10 pages) 2019.11 [Refereed]
Research paper (international conference proceedings)
We have run a Direct Numerical Simulation of a spatially developing shear mixing layer. The aim of this study is to clarify the influence of the large-scale structure on the turbulent Prandtl number Pr-T. As a main conclusion, Pr-T takes a small value (Pr-T similar to 0.5) in the dominant region of the large-scale structure. The budget analyses for the Reynolds stress equation and the scalar flux equation revealed that the differences between the momentum and scalar transfer are caused by terms related to pressure (i.e., pressure-strain correlation term, pressure-scalar gradient correlation term, and pressure diffusion terms). Phenomenally, the momentum in the field where a large-scale vortex coexists tends to be transported toward the counter-gradient direction under the influence of pressure, but the scalar is transported toward the gradient direction. As a result, it is thought that the difference in the driving force between the momentum and scalar transport causes the decrease of the Pr-T.
