TL;DR: In this paper, the authors reported the hydrothermal synthesis of single-crystalline beta-MnO2 nanorods and their chemical conversion into free-standing single crystal-stalline LiMn2O4 nanorod using a simple solid-state reaction.

TL;DR: In this paper, a facile method for reproducibly fabricating large-scale device arrays, suitable for nanoelectronics or nanophotonics, that incorporate a controlled number of sub-50-nm-diameter nanocrystals at lithographically defined precise locations on a chip and within a circuit is presented.

TL;DR: In this article, the performance of silicon nanowire electrodes has been investigated to understand the electrochemical process kinetics that influences the performance when used as a high-capacity anode in a lithium ion battery.

TL;DR: In situ transmission electron microscopy is used to study the electrochemical lithiation of high-capacity crystalline Si nanoparticles for use in Li-ion battery anodes, and analysis suggests that this behavior is due to diffusion limitation but instead to the influence of mechanical stress on the driving force for reaction.

TL;DR: It is proposed that both the high surface area nanostructure and the 2H semiconducting to 1T metallic phase transition of MoS2 are responsible for the outstanding catalytic activity.
