Two-Dimensional MoS for Li-S Batteries: Structural Design and Electronic Modulation.

Two-dimensional molybdenum disulfide (MoS ) nanosheets attract great interest for applications in lithium-sulfur (Li-S) batteries, due to their unique physical and chemical properties, which originate from diverse chemical compositions and unique electronic structures. In recent years, many efforts have been devoted to employing MoS as a polysulfide immobilizer and catalyst, functional separator, and Li-metal protection for Li-S batteries through structural design and electronic modulation. A fundamental understanding of the interplay between structural features, electronic properties, and advanced electrochemical performance is crucial for providing valuable insights for the development of Li-S batteries.

Fabrication of Orientation-Tunable Si Nanowires on Silicon Pyramids with Omnidirectional Light Absorption.

In this work, the different orientation of SiNWs on Si pyramids by a two step MACE method have been fabricated. By tuning the structure of Ag catalyst film and controlling the concentration of HO or the etching temperature, the tunability of the orientation of SiNWs from <111> to <100> on Si pyramids was realized. Si structures composed of Si pyramids and SiNWs exhibit better omnidirectional light-trapping ability by multiple reflections.

Carbon-Based Flexible and All-Solid-State Micro-supercapacitors Fabricated by Inkjet Printing with Enhanced Performance.

Abstract: By means of inkjet printing technique, flexible and all-solid-state micro-supercapacitors (MSCs) were fabricated with carbon-based hybrid ink composed of graphene oxide (GO, 98.0 vol.%) ink and commercial pen ink (2.

3D Interdigital Au/MnO2 /Au Stacked Hybrid Electrodes for On-Chip Microsupercapacitors.

On-chip microsupercapacitors (MSCs) have application in powering microelectronic devices. Most of previous MSCs are made from carbon materials, which have high power but low energy density. In this work, 3D interdigital Au/MnO2 /Au stacked MSCs have been fabricated based on laser printed flexible templates.

An extremely wideband and lightweight metamaterial absorber.

This paper presents a three-dimensional microwave metamaterial absorber based on the stand-up resistive film patch array. The absorber has wideband absorption, lightweight, and polarization-independent properties. Our design comes from the array of unidirectional stand-up resistive film patches backed by a metallic plane, which can excite multiple standing wave modes.
