Li-rich manganese-based layered cathode Li1.2Mn0.54Ni0.13Co0.13O2 (LMNCO) nanotubes are synthesized by electrospinning and surface coated with different amounts of amorphous Al2O3. The effects the coating content Al2O3 on structural electrochemical performances LMNCO investigated systematically. results show that morphologies structures samples exhibit no apparent changes after being Electrochemical tests indicate Al2O3-coated obviously enhanced performances. initial coulombic efficiency...
This letter presents a 0.18 μm CMOS dual-band frequency synthesizer with charge-pump current mismatch calibration to reduce reference spurs. To enhance accuracy the high-resolution phase detector (HRPD) is incorporated in this work. The measured output spur level less than -63 dBc after circuits are activated and reduction more 5.6 dB throughout whole range. draws 16 mA from 1.8 V power supply, covered bands 5.18-5.32 GHz 5.74-5.82 GHz.
Accurate and efficient roll mark detection on the strip steel surfaces is a fundamental but "hard" ultra-tiny target problem due to its small pixel occupation in low-contrast images. By fully exploiting prior information of marks, this article proposed Prior-Guided YOLOX network (PG-YOLOX). First, inspired by that horizontal distribution marks more uneven than vertical direction, an orthogonal context attention (OCA) carefully designed between backbone neck better capture tiny features...
The methanolic extract of the root wood Michelia compressa (Maxim.)Sargent showed cytotoxicity against MCF-7, NCI-H460 and SF-268 cancer cell lines.Bioassay-guided fractionation chloroform-soluble layer led to isolation costunolide liriodenine with cytotoxic activities, along twenty-seven known compounds.The active existed as major constituent in this study.
This letter presents a W-band wide-locking range divide-by-three injection-locked frequency divider (ILFD) implemented in 90 nm digital CMOS technology. The second-harmonic generator (SHG) is proposed to boost the second harmonic signal for effective mixing and extend locking of divider. power consumption 10.8 mW operation input ranges from 73.1 84.3 GHz. To authors' knowledge, this work first ILFD with wider than 10%.
Nickel silicide nanowires are promising interconnection and gate materials for one dimensional nanoelectronic devices. In this report, NiSi2 with low resistivity of 23.5 µΩ cm were prepared by nickel sputtering on silicon 550 °C annealing. High resolution transmission microscopy, selective area electron diffraction energy dispersive X-ray spectroscopy used to characterize the structure composition nanowires. Four-terminal electrical measurement was verify property A implantation mechanism is...
Abstract The dissolved organic matter (DOM) in the tail water of municipal wastewater treatment plant (WWTP) are complex and changeable, can react with metal ions receiving water, thus affecting their migration transformation. In order to understand characteristics DOM WWTP, Guozhen WWTP Kui river Xuzhou city were taken as research objects. spectral analysed by three dimensional fluorescence spectroscopy (3D-EEM), quality indexes such pH, total nitrogen (TN), ammonia (NH 3 − -N), nitrate...
The aim of this study is to evaluate the correlation between retinopathy and coronary microcirculation dysfunction (CMD) in type 2 diabetes mellitus (T2DM) patients.198 T2DM patients with left ventricular ejection fraction (LVEF)>50%, no epicardial artery stenosis diagnosis by angiography (CAG) successfully completed blood flow reserve (CFR) test laboratory examination were enrolled, fundus was performed on all participants. Two groups divided according CFR value, including 86 CMD (CFR≤2.5)...
With the evolution of communication technology, wireless networks have become widely adopted in many modern applications. The a Smart Grid system relies on large number low-power sensors, which stimulates vigorous development related researches. Stream Control Transmission Protocol (SCTP) is new transport-layer protocol. It combines advantages both TCP and UDP, provides features such as multi-homing multi-streaming. SCTP can provide high-performance transmission wired networks. This paper...
Conductive polymer polypyrrole (PPy)-coated lithium-rich manganese-based Li1.2Mn0.54Ni0.13Co0.13O2 (LMNCO) nanotube cathode materials were synthesized by electrospinning and subsequently subjected to low-temperature vapor-phase polymerization. X-ray diffraction (XRD), scanning electron microscopy (SEM) high-resolution transmission (HRTEM) results confirm that the successful coating of PPy layer (~2 nm) on surface LMNCO nanotubes did not destroy their morphologies or structures....
This paper presents a low power divide-by-three injection locked frequency divider (ILFD) for the V-band implemented in 65nm CMOS technology. The achieves locking range of 5.5% by using proposed harmonic-boosting technique. 71GHz to 75GHz was measured with maximum input 0dBm. inherent MOSFET non-linearity exploited generate odd-order division ratio 3. Operating an 75GHz, and 1.2V supply, consumes 2.04mW. total area including pads is 0.697mm×0.664mm.
Wireless sensor networks (WSNs) have become widely used because of their low cost and power consumption. With the IPv6 Low-power Personal Area Network (6LoWPAN) standard proposed by Internet Engineering Task Force (IETF), WSNs can be seamlessly integrated with devices running IPv6. 6LoWPAN, it will easy to manage a lot sensors via many existing network management tools. This paper illustrates design implementation an enhanced system for 6LoWPAN-based WSNs. Through simple protocol (SNMP)...
