Y zeolites have moderate microporous pore size, large specific surface area, and good hydrothermal stability, which were widely used in industrial adsorption of volatile organic compounds (VOCs), but the performance of Y zeolites in adsorption of VOCs under high humidity conditions is terrible. In this paper, Y zeolites with different silica-alumina ratios were hydrophobically modified by organosilane and characterized by XRD, FTIR, SEM, BET, NMR. In the experiments of static and dynamic adsorption of VOCs by modified Y zeolites, it can be concluded that the static water adsorption capacity of Y zeolites with silica-aluminum ratio of 5 and 40 after silica modification decreased by 62 wt% and 53 wt%, under the conditions of high humidity, GHSV = 15,000 h-1, T = 35°C and initial concentration of toluene C0 = 5000 mg·m-3. The saturation adsorption capacity of toluene was increased from 0.06 g·g-1, 0.09 g·g-1 to 0.15 g·g-1, 0.21 g·g-1, the adsorption selectivity of Y zeolites for water was reduced and that for toluene was increased after Vapor phase silanization overlay modification. The present modification method might carry out targeted modification of zeolites surface, provide research ideas and guidance under high humidity conditions.

Perpendicular magnetic anisotropy-based magnetic tunnel junctions(p-MTJs) with low Gilbert damping constant(α) are of particular interest for fast and low-power consumption magnetic random-access memory(MRAM). However, obtaining a faster switching speed and lower power consumption is still a big challenge. Herein, we report a Mo-based perpendicular double free layer structure with a low Gilbert damping constant of 0.02 relative to W-based films, as measured by time-resolved magnetooptical Kerr effect equipment. To show the influence of different film structures on the Gilbert damping constant, we measured the Mo-based single free layer. Thereafter, we deposited the full stacks with the Mo-based double free layer and obtained a high tunneling magnetoresistance of 136.3% and high thermal stability. The results of high-resolution transmission electron microscopy(HR-TEM) and energy-dispersive X-ray spectroscopy(EDS) showed that the Mo-based films had better crystallinity,sharper interfaces, and weaker diffusion than the W-based films and thus produced a weaker external contribution of the Gilbert damping constant. As a result of the weak spin-orbit coupling in the Mo-based structure, the intrinsic contribution of the Gilbert damping constant was also weak, thereby leading to the small Gilbert damping constant of the Mo-based stacks. In addition, the macro-spin simulation results demonstrated that the magnetization switching by the spin transfer torque of the Mo-based MTJs was faster than that of the W-based MTJs. These findings help to understand the mechanism behind the good performance of Mo-based p-MTJ films and show the great promise of these structures in low-power consumption MRAM or other spintronic devices.

乐种原本指流传于民间的传统器乐合奏类型,但随着民族器乐的专业化演进,在专业院团出现许多新型乐种,这些乐种或是演奏民间传统乐曲,或是根据传统音乐风格新创乐曲。由此,在传统乐种和专业作曲家创作的民族室内乐之间形成了一个新的专业化发展方向,该方向将对传统乐种的发展产生深远影响,使传统乐种逐渐脱离原有演奏语境,成为舞台艺术。而专业音乐家们,也正在努力调节传统乐种在这种语境转换后所产生的某些不适,最终将走出一条新道路。传统乐种是一种凝固的文化,新时代需要乐种保护与发展并重,进而需要提高对传统乐种的认知和审美能力。

一、"声墙"——从一篇文章中引发出的概念大部分人知道、也都听到过在某餐馆或公共区间播放的音乐,也理解这类音乐跟商业环境有一定的关系。多年前,本人在外国的中餐馆里吃饭,餐馆中播放中国的广东音乐。有外国友人问我:这家餐馆给中国交音乐版权费吗?播放音乐需要付费吗?我当时很诧异。阅读了乔纳森·斯特恩(Jonathan Sterne)写的一篇文章后对商业环境中的音乐问题有了进一步的理解,不仅如此,还引发了音乐与环境关系的思考。
