Analysis on characteristics of 1-D apodized and chirped photonic crystals containing negative refractive materials

引用

Optoelectronics Letters 2008年第6期4卷 440-442页

作者： tong Kai cui wei-wei XU Xiao-hui LI Zhi-quan College of Electric Engineering University of Yanshan Qinhuangdao 066004China

Using transfer matrix method,the optical transmission properties of 1-D photonic crystals composed partially of negative refraction media are analyzed. The transmission spectra of periodic photonic crystal,chirped photonic crystal and apodized photonic crystal are numerically simulated respectively. By contrast with optical transmission properties of ordinary photo-nic crystals made of positive refraction media,the transmission spectra of apodized photonic crystal become unregular,the Bragg flat-headed area recurs but the peak of transmission does not change significantly. Futhermore,the band gap range of chirped photonic crystal diminishes gradually.

关系抽取旨在从文本中提取出实体对之间存在的语义关系,但现有的关系抽取方法均存在关系冗余和重叠的不足,尤其是对于短文本,会因上下文信息不足而出现语义信息不足和噪声大等问题。此外,一般流水线式的关系抽取模型还存在误差传递问题。为此,文中提出一种基于并联残差膨胀卷积网络的短文本实体关系联合抽取方法。该方法利用BERT生成语义特征信息,采用并联残差膨胀卷积网络来捕获语义信息,从而提升上下文信息的捕获能力并缓解噪声。联合抽取框架通过抽取潜在关系来过滤无关关系,然后再抽取实体以预测三元组,从而解决关系冗余和重叠问题,并提高计算效率。实验结果表明,与现有的主流模型相比,所提模型在三个公共数据集NYT、WebNLG和DuIE上的F1值分别为90.9%、91.3%和73.5%,相较于基线模型均有提升,验证了该模型的有效性。

Synthetic control of chiral pore surfaces in covalent organic frameworks for enantioselective separation of chiral drugs

Science China Chemistry 2025年

作者： Shiguo Fu Xiaofeng Zhang Kaixuan Wang Linfeng Chen Fan Xia Yong cui Yan Liu School of Chemistry and Chemical Engineering Frontiers Science Center for Transformative Molecules and State Key Laboratory of Metal Matrix Composites Shanghai Jiao Tong University Faculty of Materials Science and Chemistry China University of Geosciences

Enantioselective separations of racemates using porous materials are highly attractive and significant in both fundamental research and technological applications. However, achieving controlled chiral pore surfaces to create the necessary driving force for enantiomer discrimination poses a fundamental challenge. Herein, we demonstrate that chiral covalent organic frameworks(COFs) possess the essential characteristics for effective enantioseparations through synthetic control over pore surfaces. We synthesized three 3D chiral COFs (CCOFs) featuring abundant chiral recognition sites on the pore walls via the condensation of enantiopure dialdehyde of 2,2′-dihydroxy-1,1′-binaphthyl and tetraamine. All CCOFs with high stability exhibit an 11-fold interpenetrated framework with tubular open channels, decorated with dihydroxyl or diethoxyl groups. The CCOFs with dihydroxyl groups serve as solid adsorbents for the adsorptive separation and solid-phase extraction of various chiral 1-phenylethanol-derived enantiomers, particularly racemic drugs, achieving up to 98%enantiomeric excess. In contrast, the CCOF with diethoxy groups is unable to resolve the racemates. These CCOF materials can be recycled and reused without any apparent loss of performance. Density functional theory (DFT) calculations reveal that the enantiospecific recognition arises from the well-organized chiral inner sphere and multiple chiral host-guest interactions.
