Design principles of MOF-related materials for highly stable metal anodes in secondary metal-based batteries

Interconnected hollow carbon nanospheres for stable lithium metal anodes.

For future applications in portable electronics, electric vehicles and grid storage, batteries with higher energy storage density than existing lithium ion batteries need to be developed. Recent efforts in this direction have focused on high-capacity electrode materials such as lithium metal, silicon and tin as anodes, and sulphur and oxygen as cathodes. Lithium metal would be the optimal choic...

Metal pad instabilities in liquid metal batteries.

A mechanical analogy is used to analyze the interaction between the magnetic field, electric current, and deformation of interfaces in liquid metal batteries. In the framework of a low-mode, nondissipative, linear stability model, it is found that, during charging or discharging, a sufficiently large battery is prone to instabilities of two types. One is similar to the metal pad instability kno...

Design of Biosensors Based Transition-Metal Dichalcogenide for DNA-base Detection: A First-Principles Density Functional Theory Study

The main function purpose of nanobiosensors is to sense a biologically specific material and the kind of sensing platform and doping engineering has been an emerging topic and plays an important role in monolayer molybdenum disulfide (mMoS2). In this paper, we theoretically reveal the electronic structures of mMoS2 doped by 3d transition metals. Furthermore, adsorption of nucleic acid [Adenine ...
