Effect of graphite felt properties on the long-term durability of negative electrode in vanadium redox flow battery

In our contribution we study the long-term durability of two different graphite felt materials serving as negative electrode in vanadium redox flow battery. Both electrodes differ in the precursor material and the way of activation which causes significant differences in relevant properties&...

Mixing algorithms for fixed-point iterations in self-consistent electronic structure calculations

In ab-initio calculations of electronic structure and material properties within the density-functional theory (DFT) framework, a self-consistent stationary state of a many-electron system is sought by a fixed-point iteration of Kohn-Sham equations, the so called DFT loop. One of the key com...

Silver-Doped Hydroxyapatite Coatings Deposited by Suspension Plasma Spraying

Pure hydroxyapatite suspension was produced by wet chemical synthesis. Using a hybrid water-stabilized torch, a series of HA coatings were produced on SS304 and Ti6Al4V substrates and their properties were characterized by SEM, EDX and XRD techniques. After deposition, the amorphous phase&#x...

Oxidation-Induced Structure Transformation: Thin-Film Synthesis and Interface Investigations of Barium Disilicide toward Potential Photovoltaic Applications

Barium di-silicide (BaSi2) has been regarded as a promising absorber material for high-efficiency thin-film solar cells. However, it has confronted issues related to material synthesis and quality control. Here, we fabricate BaSi2 thin films via an industrially applicable sputtering process and&#...

Highly absorbent cubic structured Siliconmonochalcogenides: Promising materials for photovoltaic applications

Exploring the high-efficiency materials for next-generation optoelectronic and photovoltaic applications is of great importance. In this article, we explore the potential of the newly designed cubic-structured Siliconmonochalcogenides (π- SiS, π-SiSe, and π-SiTe) for photovoltaic and optoelectronic applications....
