Optoelectronics Letters 2025年

作者： BI Mingpan LIU Jie ZHANG Yuchen LI Xiaolan MIAO Yinping Tianjin Key Laboratory of Film Electronic & Communicate Devices，School of Integrated Circuit Science and Engineering，Tianjin University of technology Key Laboratory of Quantum Optics and Intelligent Photonics， School of Science， Tianjin University of technology

We proposed a fast and temperature self-compensation method to detect streptomycin sulfate aqueous solution concentration based on a 2D Nb2CTXMXene nanosheets functionalized tilted Bragg grating（N-TFBG）. The introduction of 2D Nb2CTXMXene nanosheets brought more than 100% increase in sensitivity and exhibited a high sensitivity of 253.8 pm/mg/mL and detection limit 80 μg/mL in range of 0.2-0.8 mg/mL. Due to high sensitivity and compact structure， N-TFBG sensor has a faster measure time than previous method; additionally， the sensor has simultaneous temperature measurement by detecting the cladding mode and the core mode resonance peak simultaneously. Our research will hopefully open a new research platform for online detection of streptomycin sulfate concentration.

New strategy for reversal tolerant anode for automotive polymer electrolyte fuel cell

引用

Chinese Chemical Letters 2019年第6期30卷 1186-1189页

作者： Chanho Pak Seung Woo Lee Chaekyung Baik Bong Ho Lee Dae Jong You Eunyoung You Graduate Program of Energy technology School of Integrated Technology Institute of Integrated Technology Gwangju Institute of Science and Technology Gwangju 61005 Republic of Korea Fuel Cell Engineering core technology Team Division of Electric Powertrain Hyundai Mobis Co. Ltd. Yongin Gyeonggi-do 16891 Republic of Korea

Since the commercialization of the fuel cell electric vehicles (FCEVs), the polymer electrolyte membrane fuel cell system has been actively improved as a powertrain for ultimate environment-friendly vehicle. During the FCEV operation, various transient conditions such as start-up/shut-down and fuel starvation occur irregularly, which deteriorates the durability of the membrane electrode assembly. In particular, when fuel starvation occurs, the carbon support in the anode is oxidized within few minutes, thus the mitigation of this phenomenon is essential for securing the durability. This short review introduces the concept of reversal tolerant anode (RTA), which is a mitigation method using an oxygen evolution catalyst and reviews some previous reports. In addition, new approach for RTA suggested by authors recently, which is the replacement of Pt anode catalyst by multifunctional IrRu alloy catalyst that simultaneously exhibits the activities for the hydrogen oxidation reaction and the oxygen evolution reaction is introduced.

Distribution of electric field for carbon nanotube assembly: Simulation (I)

引用

Transactions of Nonferrous Metals Society of China 2011年第A01期21卷 117-120页

作者： Soon-Geun KWON Soo-Hyun KIM Kwang-Ho KIM Myung-Chang KANG Hyung-Woo LEE Department of Mechanical Engineering Korea Advanced Institute of Science and Technology (KAIST) Daejeon 305-701 Korea National core Research Center for Hybrid Materials Solution Pusan National University

The distribution of electric field for the alignment and attachment of carbon nanotubes (CNTs) was simulated. To be attached at the desired place, the aligned and attracted CNTs should be stayed in the desired area called the stable region or the quasi-stable region for an instant where the change of electric field is minimized. Since the conical electrode has the very narrow sized quasi-stable region, few CNTs can be attached. The rectangular electrodes have a wide stable region, so lots of CNTs can be attached. The results indicate that the round electrode which has a proper sized quasi-stable region is more effective for aligning and attaching a single CNT than the conical or rectangular shaped electrodes.

Distribution of electric field for carbon nanotube assembly: Experiments (II)

Transactions of Nonferrous Metals Society of China 2011年第A01期21卷 121-125页

作者： Soongeun KWON Soo-Hyun KIM Kwang-ho KIM Myung-chang KANG Hyung-woo LEE Department of Mechanical Engineering Korea Advanced Institute of Science and Technology (KAIST) Daejeon 305-701 Korea National core Research Center for Hybrid Materials Solution Pusan National University

The distribution effect of electric field on the alignment and attachment of carbon nanotubes （CNTs） were investigated. The experimental results were compared with the simulation results according to three different shaped electrodes. In previous simulation, the round shaped electrodes were expected to be more effective for aligning and attaching a single CNT between two electrodes than conical or rectangular shaped electrodes. To verify the simulation results, three different shaped electrodes were introduced and a single multi-walled carbon nanotube （MWNT） was attached. The optimal conditions for aligning and attaching MWNTs such as the frequency, applied voltage and concentration of MWNTs solution were investigated. Through repeated experiments, frequency of 100 kHz-10 MHz, applied voltage of 0.3-1.3 V^s/~m, concentration of 5 ktg/mL in MWNTs solution were obtained as a possible condition range to attach MWNTs. Under these conditions, the yield of MWNTs attachment between two electrodes was up to 70%. In previous simulation, furthermore, it was verified that the size of the stable or quasi-stable region made CNTs aligned and attached on different shaped electrodes from the comparison of the experimental and simulation results. Most single MWNT attachment was accomplished on the round shaped electrodes.

Effect of ammonia gas etching on growth of vertically aligned carbon nanotubes/nanofibers

引用

Transactions of Nonferrous Metals Society of China 2011年第A01期21卷 130-134页

作者： Sang-Gook KIM Sooh-Yung KIM Hyung-Woo LEE Department of Mechanical Engineering Massachusetts Institute of Technology 77 Massachusetts Ave Cambridge MA 02139 USA National core Research Center for Hybrid Materials Solution Pusan National University

The etching effect of ammonia （NH3） on the growth of vertically aligned nanotubes/nanofibers （CNTs） was investigated by direct-current plasma enhanced chemical vapor deposition （DC-PECVD）. NH3 gas etches Ni catalyst layer to form nanoscale islands while NH3 plasma etches the deposited amorphous carbon. Based on the etching effect of NH3 gas on Ni catalyst, the differences of growing bundles of CNTs and single strand CNTs were discussed; specifically, the amount of optimal NH3 gas etching is different between bundles of CNTs and single strand CNTs. In contrast to the CNT carpet growth, the single strand CNT growth requires shorter etching time （5 min） than large catalytic patterns （10 rain） since nano dots already form catalyst islands for CNT growth. Through removing the plasma pretreatment process, the damage from being exposed at high temperature substrate occurring during the plasma generation time is minimized. High resolution transmission electron microscopy （HTEM） shows fishbone structure of CNTs grown by PECVD.

Dielectrophoretic assembly of semiconducting single-walled carbon nanotube transistor

引用

Transactions of Nonferrous Metals Society of China 2011年第A01期21卷 126-129页

作者： Se-Hun KWON Young-Keun JEONG Soongeun KWON Myung-Chang KANG Hyung-Woo LEE National core Research Center for Hybrid Materials Solution Pusan National University Department of Mechanical Engineering Korea Advanced Institute of Science and Technology (KAIST) Daejeon 305-701 Korea

A novel burning technique for making a semiconducting single-walled carbon nanotubes （SWNTs） transistor assembled by the dielectrophoretic force was suggested. The fabrication process consisted of two steps. First, to align and attach a bundle of SWNTs between the source and drain, the alternating （AC） voltage was applied to the electrodes. When a bundle of SWNTs was connected between two electrodes, some of metallic nanotubes and semi-conducing nanotubes existed together. The second step is to burn the metallic SWNTS by applying the voltage between two electrodes. With increasing the voltage, more current flowed through the metallic SWNTs, thus, the metallic SWNTs burnt earlier than the semiconducting one. This technique enables to obtain only semi-conducting SWNTs connection in the transistor. Through the 1--V characteristic graph, the moment of metallic SWNTs burning and the characteristic of semi-conducing nanotubes were verified.
