A DFT Study on the Electronic Structures and Conducting Properties of Rubrene and its Derivatives in Organic Field-Effect Transistors

Abstract We systematically studied the electronic structures and conducting properties of rubrene and its derivatives reported recently, and disscussed the influences of electron-withdrawing groups and chemical oxidation on the reorganizati...

CoCO3 from one-step micro-emulsion method as electrode materials for Faradaic capacitors

Abstract Faradaic capacitor (FC) has been widely investigated during the past few decades, and dozens of prototypes have been proposed. However, it has not reached its full potential. In this work, we demonstrate a kind of FC comprising of ...

Electrical and magnetic properties of antiferromagnetic semiconductor MnSi2N4 monolayer

Two-dimensional antiferromagnetic semiconductors have triggered significant attention due to their unique physical properties and broad application. Based on first-principles calculations, a novel two-dimensional (2D) antiferromagnetic mate...

Catalytic effect comparison of TiO2 and La2O3 on hydrogen storage thermodynamics and kinetics of the as-milled La-Sm-Mg-Ni-based alloy

In this investigation, mechanical grinding was applied to fabricating the Mg-based alloys La7Sm3Mg80Ni10 + 5 wt.% M (M = None, TiO2, La2O3) (named La7Sm3Mg80Ni10–5 M (M = None, TiO2, La2O3)). The result reveals that the structures of as-mil...

Protective effects of ceria nanoclusters against delayed paraplegia after spinal cord ischemia

Abstract Spinal cord ischemia reperfusion injury (SCIRI) induced delayed paraplegia is a complex complication of thoracoabdominal aortic surgery. Reactive oxygen species (ROS) play a critical role in the pathogenesis of delayed paraplegia, ...

Click Chemistry in Materials Science

Despite originating only a little more than a decade ago, click chemistry has become one of the most powerful paradigms in materials science, synthesis, and modification. By developing and implementing simple, robust chemistries that do not...

Tailoring the active site for the oxygen evolution reaction on a Pt electrode

Electrocatalytic oxygen evolution is a key reaction for water splitting, but the detailed atomic structures of single-crystal electrodes under cycling conditions are still not fully understood. Here, the authors study the oxygen evolution a...

From Two-Phase to Three-Phase: The New Electrochemical Interface by Oxide Electrocatalysts

Abstract Electrochemical reactions typically occur at the interface between a solid electrode and a liquid electrolyte. The charge exchange behaviour between these two phases determines the kinetics of electrochemical reactions. In the past...

SPIN-POLARIZED PHOTOCURRENT THROUGH QUANTUM DOT PHOTODETECTOR

The theory of the photocurrent through the photodetector based on a two-level semiconductor quantum dot (QD) is presented. The analytical expressions of the matrix elements of the electronic transitions generated by the absorption of the ci...
