Robust digital receiver for EPC sensor network

引用

Journal of Systems Engineering and Electronics 2013年第1期24卷 44-51页

作者： Cheng jin Sung Ho cho Department of Electronics and Computer Engineering Hanyang University

A robust digital receiver based on a matched filter （MF） is proposed for the radio frequency identification （RFID） reader system to enhance the reliability of signal processing in the electronic product code （EPC） sensor network （ESN）. The performance of the proposed receiver is investigated by examining the anti-collision algorithm in the EPC global Class1 Generation2 protocol. The validity and usefulness are demonstrated by both computer simulations and experiments. Based on the verification results, comparing with the conventional zero crossing detector （ZCD） based receiver, the proposed receiver is very robust against strong amplitude distortions and considerable frequency deviations happening on the backscattered signal from a passive tag.

Engineering and Optimization of Silicon–Iron–Manganese Nanoalloy Electrode for Enhanced Lithium-Ion Battery

引用

Nano-Micro Letters 2017年第4期9卷 41-48页

作者： Pankaj K.Alaboina Jong-Soo cho Sung-jin cho Joint School of Nanoscience and Nanoengineering North Carolina Agricultural and Technical State UniversityGreensboroNC 27401USA

The electrochemical performance of a battery is considered to be primarily dependent on the electrode material. However, engineering and optimization of electrodes also play a crucial role, and the same electrode material can be designed to offer significantly improved batteries. In this work, Si–Fe–Mn nanomaterial alloy(Si/alloy) and graphite composite electrodes were densified at different calendering conditions of 3, 5, and 8 tons, and its influence on electrode porosity, electrolyte wettability, and long-term cycling was investigated. The active material loading was maintained very high(~2 mg cm^(-2)) to implement electrode engineering close to commercial loading scales. The densification was optimized to balance between the electrode thickness and wettability to enable the best electrochemical properties of the Si/alloy *** this case, engineering and optimizing the Si/alloy composite electrodes to 3 ton calendering(electrode densification from 0.39 to 0.48 g cm^(-3)) showed enhanced cycling stability with a high capacity retention of ~100% over 100 cycles.

Porous FeS nanofibers with numerous nanovoids obtained by Kirkendall diffusion effect for use as anode materials for sodium-ion batteries

引用

Nano Research 2017年第3期10卷 897-907页

作者： Jung Sang cho jin-Sung Park Yun Chan Kang Department of Materials Science and Engineering Korea University Anam-Dong Seongbuk-Gu Seou1136-713 Republic of Korea Department of Engineering Chemistry Chungbuk National University Chungbuk 361-763 Republic of Korea

Porous FeS nanofibers with numerous nanovoids for use as anode materials for sodium-ion batteries were prepared by electrospinning and subsequent sulfidation. The post-treatment of the as-spun Fe（acac）3-polyacrylonitrile composite nanofibers in an air atmosphere yielded hollow Fe2O3 nanofibers due to Ostwald ripening. The ultrafine Fe2O3 nanocrystals formed at the center of the fiber diffused toward the outside of the fiber via Ostwald ripening. On sulfidation, the Fe2O3 hollow nanofibers were transformed into porous FeS nanofibers, which contained numerous nanovoids. The formation of porosity in the FeS nanofibers was driven by nanoscale Kirkendall diffusion. The porous FeS nanofibers were very structurally stable and had superior sodium-ion storage properties compared with the hollow Fe2O3 nanofibers. The discharge capacities of the porous FeS nanofibers for the Ist and 150th cycles at a current density of 500 mA.g-1 were 561 and 592 mA.h-g-1, respectively. The FeS nanofibers had final discharge capacities of 456, 437, 413, 394, 380, and 353 mA-h.g-1 at current densities of 0.2, 0.5, 1.0, 2.0, 3.0, and 5.0 A.g-1, respectively.

World Journal of Clinical Cases 2022年第19期10卷 6349-6359页

作者： Jun-Hyung cho So-Young jin Digestive Disease Center Soonchunhyang University HospitalSeoul 04401South Korea Department of Pathology Soonchunhyang University HospitalSeoul 04401South Korea

Helicobacter pylori (H. pylori) infection is highly prevalent in East Asia. The overallseroprevalence rate of H. pylori infection is 44.2% in China, 37.6%-43.2% in Japan,and 51.0% in South Korea. H. pylori can cause peptic ulcer disease and gastriccancer. East Asian countries have high rates of gastric cancer (age-standardizedincidence rate: 20-30 per 100000). The Kyoto global consensus report emphasizedthat H. pylori gastritis should be considered the main cause for the development ofgastric cancer. H. pylori treatment guidelines in China, Japan, and South Koreahave recently been revised according to data from each of those ***, emerging antibiotic resistance is an important barrier to H. pylorieradication. The recommended H. pylori treatment regimens differ among thosethree East Asian countries. In this review, recent guidelines and up-to-dateresearch on H. pylori treatment regimens from China, Japan, and South Korea arediscussed.

Trifluoroethylation of Alkynes： Synthesis of Allylic-CF3 Compounds by Visible-Light Photocatalysis

引用

Chinese Journal of Chemistry 2016年第5期34卷 459-464页

Two types of allylic trifluoromethylated compounds were synthesized by reacting alkynes with CF3CH2I using visible-light photocatalysis. Subtle differences in the catalytic system controlled the selectivity of iodotrifluoroethy- lation and hydrotrifluoroethylation. The iodotrifluoroethylated products were obtained in the presence of [Ru（bpy）3]C12 and TMEDA in CH3CN under visible-light irradiation, whereas hydrotrifluoroethylated products were synthesized usingfac-[Ir（ppy）3] and a mixture of DBU and K2CO3 in DMF. The iodotrifluoroethylation reac- tion worked particularly well, even at gram-scale, and the synthetic utility of iodotrifluoroethylated products was proved by their coupling reactions, providing complex CF3-containing products.
