A model for acoustic ultrashort pulseby a disc-shaped transducer

Jinwen Ding Qingping Zhang В. М. Левин Kang Li Wei Liu

Acoustic lens is the kernel of acoustic microscopes. Its quality determines the quality of an imaging system. For impulse acoustical imaging system, it becomes more important. The ultrashort probe excited by an acoustic lens is an unique ultrasound source. Analyzing the signal structure of ultrashort pulse is the key to evaluate the acoustic lens. This paper presents a mathematic model, simulating an impulse pulse generated by a disc-shaped piezoelectric transducer of an acoustic lens, evaluating the temporal spatial distribution of the impulse wave propagation in the waveguide of the acoustic lens. The simulation results show this model is significant and practical for investigating the mechanism of acoustic ultrashort pulse and its application.

The micro-sized internal structure in acoustic image by 3D impulse scanning acoustic microscopy

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2016)

Jinwen Ding Kang Li Ning Li He Guochao Qingping Zhang

The properties of a solid specimen depend on its elastic property and microstructures, which are not only in nano size but also in micro-sized scale. Impulse acoustic microscope is a technology, employing a focused ultrasound probe beam in immersion to penetrate into a solid specimen, and to detect the internal micro-sized structure by acoustic imaging for a solid bulk material. Acoustic lens produces such a probe beam into a specimen and receives response radiations reflected from the specimen. The characters of an acoustic lens determine the precision and quality of acoustical imaging; and the relevant controlling techniques are also important peripheral elements for the system. But it is ignored or has not raised attention that the acoustic interaction behavior between the focused ultrasound probe beam and an internal micro-sized structure in a bulk — diffraction, scatter phenomena — usually also presents an inevitable impact on acoustic images. In this paper, the authors try to introduce these principles to demonstrate that these factors are the fundamental keys, to promote the performance of Impulse Scanning Acoustic Microscopy.

Hierarchical Bismuth–Carbon Microfoam Hybrid Structure Achieves Superior Sodium-Ion Storage

ACS Applied Energy Materials (2021)

Yiming Guo Gongrui Wang Bo Peng Jie Li Jinwen Ding

Bismuth (Bi) has been deemed as an attractive anode candidate for sodium-ion batteries (SIBs) due to its high theoretical volumetric capacity (3800 mAh cm–3), stable operating potential, and nontoxicity. However, a large volume change during the alloying/dealloying reaction leads to inferior cycling performance. Herein, we constructed a hierarchical bismuth–carbon microfoam-like hybrid structure composed of interconnecting Bi nanoparticles coated with a carbon shell on a carbon matrix nanocomposite (denoted as Bi@NC-MF) by a scalable and cost-effective approach, which exhibits excellent sodium-ion storage performance in terms of high specific capacity and excellent cycling stability and rate capability. Specifically, it can achieve an extraordinary capacity retention rate of 98% after 2000 cycles at a high rate of 10 A g–1. Impressively, remarkable rate capability with a capacity retention of 91% can be achieved when the current density increases from 0.5 to 40 A g–1. More importantly, a full cell by pairing the Bi@NC-MF anode with a commercial Na3V2(PO4)3/C cathode exhibits promising performance with a decent energy density of 180.6 Wh kg–1 at a power density of 59 W kg–1. This work not only provides a scalable strategy for advanced hybrid nanostructures but also stimulates the advancement of Bi-based anodes for future practical applications.

Identification of Potent Zika Virus NS5 RNA-Dependent RNA Polymerase Inhibitors Combining Virtual Screening and Biological Assays

International Journal of Molecular Sciences (2023)

Ying Chen Xiangyin Chi Hongjuan Zhang Yu Zhang Luyao Qiao

The Zika virus (ZIKV) epidemic poses a significant threat to human health globally. Thus, there is an urgent need for developing effective anti-ZIKV agents. ZIKV non-structural protein 5 RNA-dependent RNA polymerase (RdRp), a viral enzyme for viral replication, has been considered an attractive drug target. In this work, we screened an anti-infection compound library and a natural product library by virtual screening to identify potential candidates targeting RdRp. Then, five selected candidates were further applied for RdRp enzymatic analysis, cytotoxicity, and binding examination by SPR. Finally, posaconazole (POS) was confirmed to effectively inhibit both RdRp activity with an IC50 of 4.29 μM and the ZIKV replication with an EC50 of 0.59 μM. Moreover, POS was shown to reduce RdRp activity by binding with the key amino acid D666 through molecular docking and site-directed mutation analysis. For the first time, our work found that POS could inhibit ZIKV replication with a stronger inhibitory activity than chloroquine. This work also demonstrated fast anti-ZIKV screening for inhibitors of RdRp and provided POS as a potential anti-ZIKV agent.
