Spraying functional fibres by electrospinning

Chuan-Ling Zhang and Shu-Hong Yu* 

Mater. Horiz., 2016, 3, 266-269

DOI: 10.1039/C6MH00045B

Electrospinning is a very simple, robust, and versatile technique to process solutions or melts into continuous fibres with diameters down to the nanoscale, which has attracted much attention in both research and commerce. Up to now, a rich variety of electrospun fibres with controllable morphology, alignment and composition have been synthesized, and the materials composed of functional electrospun fibres have already been successfully applied in many technological areas. In particular for anisotropic nanoparticles (NPs), electrospinning shows its powerful capability to assemble them on a large scale. The goal of this brief focus article is to show you how to use the electrospinning technique for preparing the functional fibres you want.

Durable Ag/AgCl nanowires assembled in a sponge for continuous water purification under sunlight

Jin Ge, Xu Wang, Hong-Bin Yao, Hong-Wu Zhu, Yu-Can Peng and Shu-Hong Yu*

Mater. Horiz., 2015, 2, 509-513

DOI: 10.1039/C5MH00069F

A Ag/AgCl nanowire (NW) sponge and a confined flow design were put forward to improve the photodegradation efficiency of immobilized Ag/AgCl NW catalysts. In consideration of the high cost of Ag/AgCl NWs, an in situ recovery strategy was also provided to extend the lifetime of the Ag/AgCl NW sponge.

First sub-kilogram-scale synthesis of high quality ultrathin tellurium nanowires

Kai Wang, Yuan Yang, Hai-Wei Liang, Jian-Wei Liu andShu-Hong Yu*

Ultrathin semiconductor nanowires as ideal nanoscale building blocks have gained much research attention. However, the macroscopic-scale synthesis of high quality nanowires remains a challenge in the field of nanowire science and technology. Here, we demonstrate the first sub-kilogram-scale synthesis of ultrathin tellurium nanowires (TeNWs) by a one-pot scale-up hydrothermal process. As much as 150 g of uniform TeNWs with diameters of 7–9 nm and lengths of several micrometers can be synthesized. The ultra-large-scale synthesized TeNWs also can be used as a versatile template to prepare a family of high quality metal telluride nanowires in large quantities because of their high chemical reactivity and excellent dispersibility in various solvents. This research sheds light on the possibility of ultra-large-scale synthesis of high quality nanowires in the future, which is of crucial significance from the viewpoint of practical applications of functional inorganic nanowires.

A shape-memory scaffold for macroscale assembly of functional nanoscale building blocks

Huai-Ling Gao, Yang Lu, Li-Bo Mao, Duo An, Liang Xu, Jun-Tong Gu, Fei Long and   Shu-Hong Yu*

Mater. Horiz., 2014, 1, 69-73

DOI: 10.1039/C3MH00040K

A shape-memory chitosan scaffold (CSS) fabricated by an ice-templated method can be used as a versatile host matrix for self-assembly of a wide range of functional nanoscale building blocks, and thus it can produce a family of functional three-dimensional (3D) macroscale assemblies, which show promising practical application potential in various fields.
