Solid-State Hybrid Fibrous Supercapacitors Produced by Dead-End Tube Membrane Ultrafiltration

Solid‐State Hybrid Fibrous Supercapacitors Produced by Dead‐End Tube Membrane Ultrafiltration

Dead-end tube membrane ultrafiltration is used to produce a dense compact network structure in which carbon nanotubes are well dispersed between graphene layers, thereby preventing restacking of the graphene sheets and maximizing the electrochemically active surface area of the electrode. This uniform and densely compacted electrode structure results in supercapacitors with very high volumetric energy density (≈2.7 mWh cm−3).

Graphene and Carbon Nanotube Auxetic Rubber Bionic Composites with Negative Variation of the Electrical Resistance and Comparison with Their Nonbionic Counterparts

Graphene and Carbon Nanotube Auxetic Rubber Bionic Composites with Negative Variation of the Electrical Resistance and Comparison with Their Nonbionic Counterparts

Isotropic linear elastic materials such as silicone rubber are transformed in materials with auxetic behavior (i.e., negative Poisson's ratio) through microorganism digestion. Additionally, these bionic composites offer negative electrical resistance change under strain with superior toughness even if they are less dense. Through such unexpected multifunctional material properties, superior stretchablity and damage resistance, these composites pave the way for extreme applications.

Improvement of thermoelectric properties of Bi2Te3 and Sb2Te3 films grown on graphene substrate

The effect of substrates on the thermoelectric properties of Bi2Te3 (BT) and Sb2Te3 (ST) films grown by PECVD was investigated. Thermoelectric properties were strongly dependent on the deposition temperature. Power factors of the BT (ST) films on graphene substrate are higher than that of SiO2/Si. The power factor of the ST thin films grown at 300 °C, 35.9 μWcm−1K−2, is the highest value among the results regarding MOCVD processed films reported up to now.

A Quinonoid‐Imine‐Enriched Nanostructured Polymer Mediator for Lithium–Sulfur Batteries

Quinonoid imine ([BOND]NH+ [DOUBLE BOND])is proposed for anchoring polysulfides and facilitating the formation of Li2S2/Li2S in a working cell. The adsorption and redox activities of polysulfides are significantly enhanced, while the shuttle effect is largely mitigated. This provides not only new insight into the anchoring of intermediate in a working cell, but also the strategy to enhance the redox reactions on nitrogen containing functional groups.
