An Ultrahigh Capacity Graphite/LiS Battery with Holey-LiS Nanoarchitectures.

The pairing of high-capacity LiS cathode (1166 mAh g) and lithium-free anode (LFA) provides an unparalleled potential in developing safe and energy-dense next-generation secondary batteries. However, the low utilization of the LiS cathode and the lack of electrolytes compatible to both electrodes are impeding the development. Here, a novel graphite/LiS battery system, which features a self-assembled, holey-LiS nanoarchitecture and a stable solid electrolyte interface (SEI) on the graphite electrode, is reported.

Direct Observation of Highly Ordered Dendrimer Soft Building Blocks over a Large Area.

Developing large-area, single domain of organic soft-building blocks such as block copolymers, colloids, and supramolecular materials is one of the most important issues in the materials science and nanotechnology. Owing to their small sizes, complex molecular architectures, and high mobility, supramolecular materials are not well-suited for building large area, single domain structures. In the described study, a single domain of supramolecular columnar dendrimers was created over large area.

Sheathless focusing of microbeads and blood cells based on hydrophoresis.

This paper presents a microfluidic device for sheathless focusing of microbeads and blood cells based on a hydrophoretic platform comprising a V-shaped obstacle array (VOA). The VOA generates lateral pressure gradients that induce helical recirculations. Following the focusing flow particles passing through the VOA are focused in the center of the channel.
