1. Tunable stiffness of graphene oxide/polyacrylamide composite scaffolds regulates cytoskeleton assembly

Chem. Sci., 2018, Advance Article

DOI: 10.1039/C8SC02100G

Researchers from Tsinghua University have fabricated a graphene oxide/polyacrylamide composite scaffold as an extracellular matrix. This material has a tunable stiffness, through the polyacrylamide, which allowed them to investigate the effect of substrate stiffness on cytoskeleton assembly and specific gene expression during cell growth. The graphene oxide however provides surfaces for cell adhesion and growth, making the materials an attractive candidate as a scaffold material.

2. Synthesis of a 2D phosphorus material in a MOF-based 2D nano-reactor

Chem. Sci., 2018, 9, 5912-5918

DOI: 10.1039/C8SC01439F

Chinese researchers report on the use of a 2D nanoreactor for synthesising of 2D materials. Traditional approaches for generating 2D materials include interface-templates or exfoliating layered crystals, however these have their limitations. To realise a new strategy, these authors have constructed a 2D nano-reactor within a new pillar–layer metal organic framework. They demonstrate the use of the nano-reactor by demonstrating its ability to generate a 2D phosphorus material from white phosphorus.

湖北大学的研究人员报道了使用二维纳米反应器合成二维材料的方法。传统合成二维材料的方法包括界面-模板法或层状晶体剥离法，但是这些方法都有其局限性。为了实现新的合成策略，作者们在新的柱层金属有机框架内构建了一个二维纳米反应器，并成功地从白磷生成二维磷材料，证明了该纳米反应器的应用能力。

1. Integration of a functionalized graphene nano-network into a planar perovskite absorber for high-efficiency large-area solar cells

Mater. Horiz., 2018, Advance Article

DOI: 10.1039/C8MH00511G

The authors demonstrate a quasi-3D charge collection nano-network configuration for the design of large-area planar perovskite solar cells with enhanced performance. The integration of an unprecedented functionalized graphene nano-network into the perovskite absorber layer leads to the formation of a quasi 3D charge collection layer combined with a typical 2D charge-collection layer.

2. Bouncing and 3D printable hybrids with self-healing properties

Mater. Horiz., 2018, Advance Article

DOI: 10.1039/ C8MH00027A

Conventional high tech glass is brittle and does not self-heal, while conventional composites often do not achieve true synergy of their component parts. The author’s solution is a new triple network hybrid material with a unique combination of elastomeric “bouncy” behaviour and autonomous intrinsic self-healing ability, while being able to biodegrade. The transparent hybrid provides bouncy behaviour that can self-heal within seconds of fracture, without external stimulus, particularly if the fracture is internal.

传统的高科技玻璃易碎而且不可自愈，同时传统复合材料组分之间通常不能实现真正的协同作用。本文作者提出了一种新型三重网络混合材料的方案，该材料独特地结合了弹性行为和自发的本征自愈能力，同时还能够生物降解。这种透明的混合材料具有弹性行为，而且无需外部刺激便可在弯折后几秒内自愈，特别当弯折发生在其内部时。

3. Chaotic printing: using chaos to fabricate densely packed micro- and nanostructures at high resolution and speed

Mater. Horiz., 2018, Advance Article

DOI: 10.1039/C8MH00344K

This communication presents a simple, effective, and novel printing technique—one that is rooted in chaos theory and, more precisely, in the physics of chaotic mixing in a laminar regime. The main strength and differential attribute of this novel microfabrication strategy is its ability to create a densely packed microstructure at high resolution and speed in a predictable manner.

1. A 1,2,3-triazolyl based conjugated microporous polymer for sensitive detection of p-nitroaniline and Au nanoparticle immobilization

Polym. Chem., 2018, 9, 3832-3839

DOI: 10.1039/C8PY00702K

In this paper authors report the synthesis of a new conjugated microporous polymer (PTPTB), containing fluorescent 1,2,3-triazole building blocks, through an oxidative coupling reaction catalysed by FeCl₃. PTPTB displayed a typical type-II N₂ gas adsorption isotherm and had strong emissions properties. It was applied as a chemosensor for nitrogen containing aromatics and researchers found it to have a low detection limit for p-nitroaniline. Researchers also loaded PTPTB with gold nanoparticles to form a composite material, Au/PTPTB, that was employed successfully on multiple cycles as a reduction catalyst without any loss of activity.

本文作者报道了一种新的共轭微孔聚合物（PTPTB）的合成，该聚合物含有荧光1,2,3-三唑结构单元，通过FeCl₃催化的氧化偶联反应制得。PTPTB显示了典型的II型N₂ 气体吸附等温线，并具有很强的荧光发射。它被用作含氮芳烃化合物的化学传感器，研究人员发现它对对硝基苯胺具有很低的检测限。研究人员还在PTPTB中负载了金纳米粒子，形成了一种复合材料Au/PTPTB，该复合材料作为还原催化剂成功用于多次循环，且没有损失任何活性。

Researchers have used a half-sandwich scandium catalyst to synthesise new syndiotactic polystyrene materials with pendant alkenyl groups. They have reported how the alkenyl groups could be chemically converted into desirable functional groups, using thiol-ene click chemistry or epoxidations, thereby overcoming a key difficulty faced by researchers working on syndiotactic polystyrene.
