Abstract:
Carbon nanotube (CNT)/copper composites offer promise as lightweight temperature-stable electrical conductors for future electrical and electronic devices substituting copper. However, clarifying how constituent nanotube structures influence CNT/Cu electrical performances has remained a major research challenge. Here, we investigate the correlation between the CNT/Cu electrical performances and nanotube structure by preparing and characterizing composites containing nanotubes of different structural attributes. We prepared three types of composites—single-wall (SW)-CNT/Cu wires, SW-CNT/Cu pill

Abstract:
Photocatalysts exhibiting high activity for the degradation of 1,4-dioxane (1,4-D) have been a subject of intense focus due to their high toxicity and challenging degradability. Bismuth oxide (Bi2O3) is recognized as an ideal photocatalyst; however, there have been limited studies on its effectiveness in 1,4-D degradation. It is crucial to address the issue of low photocatalytic efficiency attributed to the instability and easy recombination of photogenerated electrons and holes in Bi2O3 upon photoexcitation. In this study, Cu-MOF and oxygen vacancy were utilized to improve the 1,4-D photocata

Abstract:
The development of stable air electrodes for Solid Oxide Cells operating at reduced temperatures (≤700°C) creates unique material design challenges. These electrodes must not only show excellent oxygen evolution and oxygen reduction reaction rates, but also be able to maintain these fast rates over the 40,000hr lifetimes envisioned for solid oxide cells. One material of significant interest for this is Sr(Ti0.3Fe0.7)O3-δ (STF), which is a mixed ionic-electronic conducting (MIEC) perovskite that has shown performance similar to that of LaxSr1-xCoyFe1-yO3-δ (LSCF) (1).

Abstract:
Graphene platelets can impart unique properties to metal matrices, such as enhanced conductivity, mechanical, thermal properties and catalytic activity.1,2 The electrodeposited process to fabricate composite metal matrices has an advantage over other techniques because it can avoid high heat treatment and deformation during fabrication, which can damage the intrinsic structure of graphene plates. Graphene itself is difficult to disperse and incorporate into electrodeposited films, but the oxidized form, having abundant surface functional groups, can be readily dispersed into aqueous solutions.

Abstract:
Boosting the lower oxygen reduction reaction (ORR) activity of perovskite cathode material is essential for the development and widespread use of IT-SOFC. Oxygen ion migration at the cathode-electrolyte interface can enhance by introducing structural modifications consisting of high grain boundary density and heterointerfaces [1]. Herein, we fabricated Sr2CoNbO6- δ @Sm0.2Ce0.8O1.9 (SCNO@SDC) nanofiber composite using an electrospinning technique and examined the electrochemical impedance for the symmetric cell in air atmosphere. The distinct phases of SCNO and SDC were observed from XRD and FE

Introduction. Inflammation susceptibility and the nature of combustion are one of the most important characteristics for the parametrization of the fire hazard of polymer materials. Because ignition is the occurrence process of the persistent flame near the surface of the material, which is preceded by the process of propagation of the flame front on its surface, the predisposition to ignition of the polymer materials plays an important role in the aspect of initiation of fires.

Abstract:
Electrochemical conversion of carbon dioxide (CO2) gas is a simple and cost-benefit method to produce economically valuable materials such as carbon monoxide (CO), multi-carbon (C2+) oxygenate, and hydrocarbons. In particular, ethanol (EtOH) production is attractive to be applied for conventional transport fuels. However, there has been a lack of techniques to yield predominant EtOH from CO2. Copper (Cu), as the well-known and exclusive C2+ catalyst, thermodynamically prefers the production of (C2H4) compared to EtOH. Previous studies suggested that increased concentration of carbon monoxide (
