| 1 | THz spectra of five borates crystals显示文摘Terahertz spectral responses have been studied for five borate crystals Na5[B2P3O13] (NBP), Zn3BPO (ZBP), SrB4O7 (SBO), Na3La9O3(BO 3)8 (NLBO) and PbB4O7 (PBO). It is found that the samples had good transmission in 0.25―1.5 THz region. Both SBO and NLBO have an absorption coefficient less than 10 cm1. Among them, SBO has not only the smallest absorption coefficient but also a very flat dispersion in the frequency region under investigation. Distinct resonance absorption peaks are observed for ZBP at ν1 = 1.4 THz, ν2 = 2.0 THz and SBO at ν = 2.4 THz. In the spectrum of PBO, two abnormal dispersions appear in the frequency regions 1.44―1.74 and 2.2―2.5 THz. The absorption coefficients and refraction indices of the five crystals are extracted from the THz time-domain (THz-TDS) spectra in 0.25―2.5 THz region. The properties and origins of the spectral responses are addressed. | HOU BiHui WANG YaLi WU YiCheng CHEN Hua WANG Li FU PengZhen LIU FengYan | 2008 | Chinese Science Bulletin2008，53，1： | 2 |
| 2 | Integrated photonic RF self-interference cancellation on a silicon platform for full-duplex communication显示文摘In-band full-duplex(IBFD) technology can double the spectrum utilization efficiency for wireless communications,and increase the data transmission rate of B5G and 6G networks and satellite communications. RF self-interference is the major challenge for the application of IBFD technology, which must be resolved. Compared with the conventional electronic method, the photonic self-interference cancellation(PSIC) technique has the advantages of wide bandwidth, high amplitude and time delay tuning precision, and immunity to electromagnetic interference.Integrating the PSIC system on chip can effectively reduce the size, weight, and power consumption and meet the application requirement, especially for mobile terminals and small satellite payloads. In this paper, the silicon integrated PSIC chip is presented first and demonstrated for IBFD communication. The integrated PSIC chip comprises function units including phase modulation, time delay and amplitude tuning, sideband filtering, and photodetection, which complete the matching conditions for RF self-interference cancellation. Over the wide frequency range of C, X, Ku, and K bands, from 5 GHz to 25 GHz, a cancellation depth of more than 20 dB is achieved with the narrowest bandwidth of 140 MHz. A maximum bandwidth of 630 MHz is obtained at a center frequency of10 GHz. The full-duplex communication experiment at Ku-band by using the PSIC chip is carried out. Cancellation depths of 24.9 dB and 26.6 dB are measured for a bandwidth of 100 MHz at central frequencies of 12.4 GHz and14.2 GHz, respectively, and the signal of interest(SOI) with 16-quadrature amplitude modulation is recovered successfully. The factors affecting the cancellation depth and maximum interference to the SOI ratio are investigated in detail. The performances of the integrated PSIC system including link gain, noise figure, receiving sensitivity, and spurious free dynamic range are characterized. | XIUYOU HAN XINXIN SU MENG CHAO XINDI YANG WEIHENG WANG SHUANGLING FU YICHENG DU ZHENLIN WU MINGSHAN ZHAO | 2023 | Photonics Research2023，11，10： | 1 |

| 19 | Repolarization reserve, arrhythmia and new drug development显示文摘Repolarization-related lethal arrhythmias have led to the concept of“repolarization reserve”,which may help elucidate the relationship between K^(+) currents and other components of repolarization.Pharmacological manipulation as well as congenital and cardiac disease may affect repolarization and alter the repolarization reserve,leading to the development of arrhythmias.Pharmacological enhancement of outward currents or suppression of inward currents has been shown to be of therapeutic value.A number of newly found selective ion channel inhibitors or agonists have been investigated for their ability to enhance repolarization reserve and decrease the incidence of arrhythmia.In this paper we review the development,potential mechanisms,clinical application,and pharmacological significance of repolarization reserve in order to better understand,predict and prevent unexplained adverse cardiac events. | Yang Li Yicheng Fu | 2013 | Acta Pharmaceutica Sinica B2013，3，3： | 0 |
| 20 | Efficient anion immobilization enabled by structurally controllable halloysite for dendrite-free sodium metal anode显示文摘Sodium metal has shown great potential as an inexpensive anode for rechargeable batteries. However, the growth of sodium dendrites continues to hinder the commercialization of Na metal batteries. Herein, an effective strategy using anion-anchoring halloysite nanotube(HNT) coating was proven to prevent the diffusion of anions and trigger uniform Na deposition. Through theoretical calculation, a model of active site of fixed anions exposed from HNTs after acid activation was established for the first time, revealing that Si–Al sites are effective active site of acid-activated HNTs. Furthermore, HNTs with strong and effective adsorption capacity for anions were obtained by controlling the structure of HNTs to regulate the exposure of Si–Al sites. The strong interaction between sites of acid-activated HNTs and the SO_(3)CF_(3)^(-) anion effectively promotes the dissociation of sodium salts, the release of Na^(+) and subsequent migration. As a result, HNTs acid activation for 4 h shows a steady sodium deposition process and displays high Coulombic efficiency in half cell, long cycle life in symmetric cell and full cell. This work provides a basic theoretical basis for the design of nanoclay with abundant and effective active site to fix anions for dendritic free metal batteries. | Caihong Yang Yicheng Hua Ying Zhang Jie Wang Huanwen Wang Liangjie Fu Aidong Tang Huaming Yang | 2023 | Science China Chemistry2023，66，9： | 0 |
