growing 3D-Cu coating to improve the reversibility and reaction kinetics of Zn metal anodes.

The zinc metal anode is the most promising metal anode material in aqueous battery systems due to its low cost and high theoretical capacity. However, it still undergoes irreversible reactions such as premature failure of the dendrites/dead Zn during Zn stripping/plating, resulting in the inferior cycling stability of the Zn-based full cell. Here, we demonstrate a facile 3D-Cu alloy coating to improve Zn reversibility by providing spatial voids to accommodate the plated Zn to form dendrite-free morphology.

Rapid synthesis of monodispersed Au-Ag alloy nanosponges using selective laser melting and dealloying for sensitive near-infrared surface-enhanced Raman scattering.

We developed a rapid synthesis method for monodispersed Au-Ag alloy nanosponges (NSs) with high density of 'hotspots' for near-infrared surface enhanced Raman scattering (NIR-SERS) by a selective laser-irradiation melting and chemical dealloying process. Au@Ag core-shell nanocubes were firstconverted into solid alloyed Au-Ag nanospheres by a rapid laser irradiation igniting quick fusion and quenching process within two minutes. The alloyed Au-Ag nanospheres transformed into Au-Ag alloy NSs after treated by a chemical dealloying process.

Cortical thickness, gyrification and sulcal depth in trigeminal neuralgia.

Neuroimaging studies have documented brain structural alterations induced by chronic pain, particularly in gray matter volume. However, the effects of trigeminal neuralgia (TN), a severe paroxysmal pain disorder, on cortical morphology are not yet known. In this study, we recruited 30 TN patients and 30 age-, and gender-matched healthy controls (HCs).

A pilot study on the application of FFE and SSh-TSE sequences in ocular MRI.

Purpose: To preliminarily investigate the application value of rapid sequences FFE and SSh-TSE in ocular magnetic resonance imaging (MRI).

Methods: Ocular MRI was performed in 18 subjects without ocular conditions,and demonstration of 15 delicate anatomic structures on two sequences in each subject was rated by three proficient physicians.

Results: FFE sequence was comparatively advantageous in demonstrating delicate structures on ocular wall and ocular adnexa (P<0.

[Correlation analysis between multi-slice CT perfusion imaging and microvessel density in ovarian tumors].

Objective: To analyze the correlation between the perfusion data and microvessel density (MVD) in ovarian tumors, and investigate the hemodynamic features of the tumors in terms of anatomy and functional CT imaging.

Methods: Six patients with surgically confirmed benign ovarian tumors and 6 with malignant ovarian tumors underwent multi-slice CT perfusion imaging to acquire the perfusion parameters including perfusion, PEI, TTP, BV peak enhancement image(PEI), time to peak(TTP) and blood volume(BV). The tumors were stained and counted by Immunohistochemical staining of the microvessels in the tumor was performed to detect the MVD.
