The solvothermal/hydrothermal method is an important technology for producing semiconductor nanowires at low temperature. This paper presents an integrated discussion of nanowire growth, mainly from four aspects in the solvothermal/hydrothermal process. These aspects, including materials with highly anisotropic crystal structures, coordination directing/mixed solvents, surfactants/capping reagents, and reaction at relatively high temperature, have a key effect on nanowire formation in the solvothermal/hydrothermal process. These factors have instructional significance for nanowire synthesis and research of their growth process in the future.

Surface-immobilized pure DNA hydrogels were formed using a surficial primer-induced strategy and adopted as scaffold materials for biosensing applications.

Although different kinds of metal oxide nanoparticles are extensively investigated as anode materials for lithium-ion batteries (LIBs), their cycle life and energy/power density are still not suitable for commercial applications. Metal oxides have a large storage capacity, but they suffer from low electrical conductivity and severe volume change during the charge/discharge process. Herein, we present a facile route to prepare self-assembled ZnO/Co3O4 nanocomposite clusters through calcination of preformed Prussian Blue Analogue (PBA) Zn3[Co(CN)6]2 nanospheres. These self-assembled ZnO/Co3O4 nanocomposite clusters exhibit superior lithium storage capabilities with good cycling properties. A reversible capacity of 957 mA h g(-1) was retained at a current density of 100 mA g(-1) up to 100 cycles. The enhanced electrochemical performance of the ZnO/Co3O4 nanocomposite anode can be ascribed to the rational design of the self-assembled cluster structures and the synergetic effect of two-component functional nanoparticle systems.
