A Fast and Stabilized Method for Gratings

IEEE Photonics Technology Letters (2014)

Tian‐lin Dong Boyuan Chen Lin Li Qi Huang Jin Li

The widely used Rayleigh expansion is not generally bounded and causes the instability and some limitations in numerical process. We extend the radiation condition for diffraction grating problems and stress that the radiation field excited by a planar periodic current source satisfies the generalized radiation condition; hence, it can be used as a modified Rayleigh expansion to formulate an enhanced Rayleigh method. The proposed method can considerably extend the domain of validity. Invoking the internal regularization mechanism, it can work with success when amplitude/period ratio equals 0.5 or higher for a sinusoidal metal grating and s polarization with normal incidence. At the same time, the simplicity, efficiency, and ability to explicitly depict the interactions among diffracted orders are as good as, if not better than in the Rayleigh method.

Preparation and Antibacterial Properties of PLA-Based Composite Nanofiber Membrane Material Loaded with Cationic Antibacterial Agent by Electrospinning

Coatings (2023)

Hongyu Gong Lin Li Na Li Lina Tian Tao Zhang

With the continuous application of antibacterial materials, various problems have emerged, such as expensive prices and the potential development of resistance. Cationic antibacterial agents, due to their high solubility, reactivity, and antibacterial properties, are considered as environmentally friendly and cost-effective antibacterial agents. In addition, the electrospinning technique is recognized as a versatile and high-efficiency method to produce nanofibers with multifunctional properties and adjustable structures. In this work, we prepared a series of nanofiber membranes by electrospinning technology using hexadecyl trimethyl ammonium Bromide (CTAB) and 5-Chloro-8-hydroxyquinoline (5-Cl8Q) as antibacterial agents and polylactic acid (PLA) as substrate. The antimicrobial performance of PLA/CTAB/5-Cl8Q was the highest among the prepared materials, which inhabited S. aureus and E. coli up to 99.9% and 95.9%, respectively, and the antibacterial properties were stable. In general, PLA/CTAB/5-Cl8Q has great development potential, and it can be applied to real life as a cost-effective, biodegradable and highly antibacterial material.

Nitrogen-doped carbon dots for sensitive detection of ferric ions and monohydrogen phosphate by the naked eye and imaging in living cells

Nanoscale Advances (2020)

Qiaoling Liu Borong Ren Kai‐Xin Xie Yanmei Yan Ruirong Liu

Nitrogen doped carbon dots (N-CDs) have been prepared via a one-pot hydrothermal method by using formamide and o-phenylenediamine as the carbon precursors. The as-fabricated N-CDs display excellent water dispersibility, good biocompatibility and anti-photobleaching properties. A strong emission band with an emission maximum (λflmax) of 556 nm is observed under 450 nm excitation, and a large Stokes shift of 106 nm is presented. However, the fluorescence is quenched by the addition of Fe3+; a good linearity is shown in the range of 0-65 μM with a detection limit as low as 0.85 μM. Fortunately, the quenched fluorescence could be recovered rapidly by the addition of monohydrogen phosphate (HPO42-) due to the formation of the stable [N-CDs-Fe3+-HPO42-] complex, and a good linearity is exhibited in the range of 0-60 μM with a low detection limit of 0.80 μM for HPO42-. A novel "on-off-on" fluorescence response is seen with an obvious color change from yellow-crimson-yellow by the naked eye. In addition, the confocal microscopy images suggest that the as-synthesized N-CDs could serve as a sensitive nanosensor for Fe3+ and HPO42- detection, implying the diverse potential application of N-CDs in the biomedical field.

Analysis of Chemical Variations between Crude and Salt-Processed Anemarrhenae rhizoma Using Ultra-High-Performance Liquid Chromatography–Mass Spectrometry Methods

Molecules (2017)

De Ji Xiaonan Su Ziyan Huang Lialin Su Lin Li

The present study was designed to systematically investigate the chemical profile differences between crude Anemarrhenae rhizoma (CAR) and salt-processed Anemarrhenae rhizoma (SAR). Ultra-high-performance liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC–QTOF-MS), coupled with multivariate statistical analysis was used for the discrimination of chemical profiles and the identification of the differentiation of the chemical constitutions of CAR and SAR. In addition, seven main constituents of CAR and SAR were simultaneously determined by ultra-high-performance liquid chromatography–quadrupole mass spectrometry (UHPLC–MS) for analyzing the content variations. A total of 24 components were found to be the main contributors to the significant difference between CAR and SAR. The structures of the marker compounds were identified based on their chromatographic behaviors, intact precursor ions, and characteristic MS fragmentation patterns. The potential structural transformation mechanism of furostanol saponins during salt processing was explored. The results may provide a scientific foundation for deeply elucidating the processing mechanism of Anemarrhenae rhizoma.

Ultralow Scattering and Broadband Metasurface Using Phase Adjustable FSS Elements Embedded With Lumped Resistors

IEEE Antennas and Wireless Propagation Letters (2021)

Chengli Li Zhuang Xu Lin Li Sai Guo Yun He

This letter presents a novel phase-cancellation and absorptive metasurface (PCAM) with ultralow scattering and broadband features. The PCAM is formed by two circular frequency selective surface elements with lumped resistors, which can not only reduce reflection amplitudes by transforming the incident waves into heat but also adjust reflection phase responses simultaneously. The two electromagnetic scattering mechanisms, phase cancellation and absorption, cooperate in the same band and single layer. This is the first proposed ultralow backscattering performance where the monostatic radar cross section (RCS) is reduced by more than 20 dB in 5.0–10.9 GHz. Simultaneously, an RCS reduction over 10 dB is achieved at a broad frequency band of 4.1–12.0 GHz under normal incidence. Both the analysis and measurements are demonstrated in detail. The good agreement between simulated and measured results validates the proposed PCAM.
