Conventional Ni/yttria stabilized zirconia (YSZ) fuel electrode supported solid oxide electrolysis cells (SOECs) demonstrate acceptable long-term durability when operated at below -1 A/cm2. These suffer however severe degradation above A/cm2, where a large part of the cell resistance increase is associated with Ni/YSZ electrode. In this work, by introducing Ce0.8Gd0.2O2-d (CGO) nanoparticles in...

In this work, we propose a method to improve electro-optical and structural parameters of light-absorbing kesterite materials. It relies on the application of weak power hydrogen plasma discharges using electromagnetic field of radio frequency range, which improves homogeneity of the samples. The method allows to reduce strain of light absorbers and is suitable for designing solar cells based o...

Group 14 elements (C, Si, and Ge) exist as various stable and metastable allotropes, some of which have been widely applied in industry. The discovery of new allotropes of these elements has long attracted considerable attention; however, the search is far from complete. Here we computationally discovered a tetragonal allotrope (12 atoms/cell, named T12) commonly found in C, Si, and Ge through ...

The thermochemlcal stablllty of fast oxygen ion conductlng yttria stabillzed blsmuthoxlde (YSB) r solld solutlons containing 22.0 32.5 mol% of yttrla was investigated. It was shown that In the temperature range between 650 740 C the stabilized cublc ~ -phase contalnlng less than 31.8 mol% of yttrla ls not stable durlng long term annealing treatments (>~500 hours). During annealing at 650 C a sl...

Crystal structure and compressibility of potassium azide was investigated by in-situ synchrotron powder X-ray diffraction in a diamond anvil cell at room temperature up to 37.7 GPa. In the bodycentered tetragonal (bct) phase, an anisotropic compressibility was observed with greater compressibility in the direction perpendicular to the plane containing N3 ions than directions within that plane. ...

Gold nanoparticles (Au NPs) were synthesized in single-crystalline yttria-stabilized zirconia (YSZ) using a high-energetic gold ion implantation with the intention of subsequent modification by silicon irradiation. (100)-oriented YSZ samples implanted 1 MeV Au + ions at room temperature and fluences 1.5×10 16 cm −2 , 5.0×10 7.5×10 subsequently annealed for h 1100 °C air. NPs was realized irradi...

Thermoplastic extrusion based additive manufacturing (MEX-AM), is a very interesting fabrication method for the shaping of larger ceramic parts. Commercial filaments are currently available in market, but due to lack information from suppliers, it not easy select suitable filament material 3D printing individual objects. In this study, three commercial yttria-stabilized zirconia (YSZ) provided ...

Ti(β) alloys have become an important class in the biomedical field due to low Young’s modulus, excellent physical properties, and biocompatibility. However, their like biocompatibility and, also, wear resistance, can be still enhanced. To improve those a composites approach applied. This research shows new of composite structure fabrication by powder metallurgy methods which for stabile yttria...

Background: Reinforcement of dental acrylics with fillers has yielded positive results. Different proportions have been added to strengthen the acrylics, but no consensus reached. Aim: The purpose this study was investigate effects addition different concentrations yttria-stabilized zirconium (YSZ) obtained from residues generated CAD-CAM milling YSZ on microstructure and mechanical properties ...
