TL;DR: Because lithiation-induced volume expansion, plasticity, and pulverization of electrode materials are the major mechanical effects that plague the performance and lifetime of high-capacity anodes in lithium-ion batteries, these observations provide important mechanistic insight for the design of advanced batteries.

TL;DR: This anisotropic swelling results in lithiated Si nanowires with a remarkable dumbbell-shaped cross section, which develops due to plastic flow and an ensuing necking instability that is induced by the tensile hoop stress buildup in the lithiated shell.

TL;DR: Advanced in situ transmission electron microscopy shows that the addition of a carbon coating combined with heavy doping leads to record-high charging rates in silicon nanowires, providing important insight in how to use Si as a high energy density and high power density anode in lithium ion batteries for electrical vehicle and other electronic power source applications.

TL;DR: In this paper, a simple procedure for fabricating flexible, free-standing, and magnetic film of GO/CNT-Fe3O4 composites by using a one-pot co-precipitation in situ growth route was reported.

TL;DR: In this paper, the effect of different sizes of hollow carbon nanospheres (HCNs) on microwave absorption has been investigated and it was shown that HCNs with an outer diameter of ∼70 nm and inner diameter of 30 nm exhibit the best microwave absorption performance.
