Agent-free, highly sensitive, and simply operated Ag sensor with molybdenum disulfide-based field effect transistor.

Ag, as a good bactericidal reagent, has been extensively used to prevent the growth and spread of bacteria and viruses. However, overcommit of Ag would leave residues in environments, which is toxic to the human body even under minimal exposure. In this case, a fast and high selective sensing method based on field effect transistors (FET) has been proposed for monitoring Ag in aqueous solutions.

In-Situ Construction of Anti-Aggregation Tellurium Nanorods/Reduced Graphene Oxide Composite to Enable Fast Sodium Storage.

Sodium-ion batteries (SIBs) as a replaceable energy storage technology have attracted extensive attention in recent years. The design and preparation of advanced anode materials with high capacity and excellent cycling performance for SIBs still face enormous challenges. Herein, a solution method is developed for in situ synthesis of anti-aggregation tellurium nanorods/reduced graphene oxide (Te NR/rGO) composite.
