2. Programming 2D/3D shape-shifting with hobbyist 3D printers

Mater. Horiz., 2017, Advance Article.

DOI: 10.1039/C7MH00269F

Shape-shifting materials are of significant interest as complex 3D shapes can be combined with precisely controlled surface functionalities such as bio-nanopatterns and printed electronics. A novel shape-shifting technique is presented by Professor Zadpoor et al from TU Delft that requires only a hobbyist 3D printer and inexpensive off-the-shelf materials.

形状转换材料可以将复杂的3D形状与可精确调控的表面功能（如生物纳米图案和印刷电子器件）结合起来，得到研究工作者的高度关注。来自荷兰代尔夫特理工大学的Zadpoor教授及其团队发展了一种新颖的形状转换技术，只需要一台非专业的3D打印机和廉价现成的材料便可实现。

1. Catechol adsorption on graphene nanoplatelets: isotherm, flat to vertical phase transition and desorption kinetics

Chem. Sci., 2017, 8, 4771-4778

DOI: 10.1039/C7SC01331K

Researchers from Oxford University have demonstrated a new strategy to study the adsorption and desorption of catechol on graphene nanoplatelets. Electrochemical and spectroscopic investigations found adsorption to be Langmuirian at low concentrations, with a flat to vertical phase transition occurring at high concentrations. Desorption kinetics exhibited a first order process. This method has the potential to be used to characterise a range of molecules on nanomaterials.

牛津大学的研究人员在这篇论文中展示了一种研究儿茶酚在石墨烯纳米片上吸附和解吸的新策略。相关的电化学和光谱研究发现，在低浓度下吸附行为符合Langmuir方程，而在高浓度下发生水平到垂直的相变。解吸动力学研究表明这是一个一级过程。这种方法有望用于表征纳米材料上的一系列分子。

2. Is iron unique in promoting electrical conductivity in MOFs?

Chem. Sci., 2017, 8, 4450-4457

DOI: 10.1039/C7SC00647K

US, UK and Korean scientists investigated metal ions that optimize charge transport and charge density in metal-organic frameworks, to improve electrical conductivity in these materials. The electrical conductivity and activation energy for 20 MOFs were measured, with iron found to lead to the best electrical properties. This was attributed to the high-energy valence electrons of Fe²⁺ and the Fe^2+/3+ mixed valency. These findings reveal strategies that could be used to improve electrical conductivity in these porous materials.

美国、英国和韩国的科学家对优化金属-有机框架（MOF）中的电荷传输和电荷密度的金属离子进行研究，从而提高材料的导电性。他们测试了20种MOF的电导率和活化能，发现铁基MOF具有最好的电学性质，原因在于Fe²⁺ 具有高能价电子和 Fe^2+/3+混合价。该研究可用于提高这些多孔材料的电导率。
