Material Horizons (IF: 10.706)

1. A tale of two membranes: from poly (ionic liquid) to metal–organic framework hybrid nanoporous membranes via pseudomorphic replacement

Mater. Horiz., 2017, Advance Article.

DOI: 10.1039/C7MH00193B

A general approach is presented by Professor Jiayin Yuan and Materials Horizons Editorial Board Member Professor Markus Antonietti to produce a variety of free-standing asymmetric MOF hybrid membranes and superstructure arrays on "inert" substrates with tailored crystal sizes and shapes. One such membrane is the first example of a MOF-based actuator.

德国马普胶体与界面研究所与美国克拉克森大学袁家寅教授和Materials Horizons 编辑委员会成员Markus Antonietti教授等科学家开发了一系列可在“惰性”基底上“自由站立”的非对称MOF杂化膜和超结构阵列，这些MOF材料具有可调的晶体尺寸和形状。其中的一种膜作为基于MOF的致动器，尚属首次报道。

2. Optimal sound-absorbing Optimal sound-absorbing structures

Mater. Horiz., 2017, Advance Article.

DOI: 10.1039/C7MH00129K

A "sound absorption by design" strategy is introduced by researchers from HKUST, highlighting the use of sound-absorbing metamaterials. Conventional sound absorbing materials have fixed absorption spectra, which can only be adjusted by varying the sample thickness. In this work, researchers use the "causality constraint" to delineate what is ultimately possible for sound absorbing structures.

香港科技大学的研究人员在这篇论文中提出了“设计吸声”的策略，突出展示了吸声超材料的应用。 传统吸声材料具有固定的吸收声谱，只能通过改变样品厚度来调节。在这项工作中，研究人员利用“因果约束”的概念勾勒出吸声结构的极限可能性。

3. A new class of chiral semiconductors: chiral-organic-molecule-incorporating organic–inorganic hybrid perovskites

Mater. Horiz., 2017, Advance Article.

DOI: 10.1039/C7MH00197E

A new class of chiral semiconductors has been developed by Professor Jooho Moon and coworkers at Yonsei University. While inorganic chiral semiconductors are rare, the recent discovery that chirality can be transferred from chiral organic molecules to semiconducting quantum dots has increased the range of chiral semiconductors available. This new class of chiral organic-molecule-incorporating organic-inorganic hybrid perovskite semiconductor presented here is independent of colloidal chemistry, potentially facilitating the development of advanced optic and spintronic devices.

韩国延世大学的Jooho Moon教授和同事们开发了一类新的手性半导体材料。无机手性半导体较为罕见，不过人们最近发现手性有机分子可以将“手性”传递给半导体量子点，由此可获得更多手性半导体材料。本文介绍的这一类新型包含手性有机分子的有机-无机杂化钙钛矿半导体材料不受胶体化学的影响，有可能促进先进光学和自旋电子器件的开发。

2. Functional metal–organic framework boosting lithium metal anode performance via chemical interactions

Chem. Sci., 2017, 8, 4285-4291

DOI: 10.1039/C7SC00668C

Scientists in Beijing and Yale University report the first study of metal organic framework (MOF) materials for enhancing the electrochemical performance of lithium metal electrodes. The high performance is attributed to higher Li⁺ transference numbers and uniform Li⁺ nucleation. This work provides a new approach of utilizing MOF materials for Li anode protection.

耶鲁大学和北京大学的科学家们首次报道了利用金属有机框架（MOF）材料来增强锂金属电极的电化学性能。其高性能的原因在于更高的Li⁺迁移数和均匀的Li⁺成核。这项工作为利用MOF材料进行Li负极保护提供了新的方法。
