Introduction
Looking for talented Ph.D's and Post-docs to join our group and study oxide glass plasticity at room temperature. My main work concentrates on studying the fundamental mechanical properties of ceramic materials. Deformation mechanisms are studied using in situ electron microscopy. This involves overcoming challenges and finding new routes in processing of ceramics and using atomistic simulations and finite element simulations to understand and verify in situ test results.

Objective: The aim of this study was to evaluate the mechanical properties of 3D printed zirconia (ZrO2). Materials and Methods: The test specimens were produced with a 3D printer that uses lithography-based ceramic manufacturing (LCM) technique with two different parameters in horizontal and vertical printing orientations. Altogether four groups...

Oxide glasses are an integral part of the modern world, but their usefulness can be limited by their characteristic brittleness at room temperature. We show that amorphous aluminum oxide can permanently deform without fracture at room temperature and high strain rate by a viscous creep mechanism. These thin-films can reach flow stress at room tempe...

The aim of the IL TROVATORE project is the development, characterization and testing of potential materials for nuclear fuel rod claddings with enhanced accident tolerance. One main task of the ongoing investigations are testing of the cladding/coolant interactions under operational as well as accident conditions. A wide range of materials was alre...

The Young Ceramists Network (YCN) was established by the European Ceramic Society (ECerS) to build a platform to promote the networking between young researchers and professionals that are active in the ceramic-related fields worldwide from academia to the industrial sector. With the help of the newly established open access journal, Open Ceramics,...

Synthesis of graphene oxide by the modified Hummers method and measuring the synthesis yield were investigated. Based on the results, a comprehensive method to measure graphene oxide synthesis yield was proposed, which will allow comparison of future literature results. In addition, changes are proposed to the exfoliation procedure to improve the y...

In this study, the pulsed laser ablation in liquids (PLAL) technique was used on titanium in deionized water at different laser powers to understand its effect on the synthesis yield of nanoparticles. A 500-ns 1062-nm fiber laser at 25 kHz was used to effect PLAL of titanium to produce nanoparticles. TEM images of the synthesized nanoparticles show...

This paper aims to introduce small angle X-ray scattering (SAXS) as a promising technique for measuring size and size distribution of TiO2 nanoparticles. In this manuscript, pulsed laser ablation in liquids (PLAL) has been demonstrated as a quick and simple technique for synthesizing TiO2 nanoparticles directly into deionized water as a suspension...

Introduction Recent TEM in situ mechanical experiments on single alumina nanoparticles have shown unexpected plasticity in room temperature alumina [1, 2]. These results push the theoretical boundaries of ceramics mechanical ductility towards comparable levels with metals. The important questions for materials science now are: (i) whether the plast...

To study the microstructure and mechanical properties of alumina nanocomposites, Al2O3/2.5 vol.% Ni and Al2O3/10 vol.% ZrO2 nanocomposites were consolidated by pulsed electric current sintering (PECS). Fracture toughness was found to increase by 13 % and 16 % respectively compared to reference alumina. Hardness increased slightly in Al2O3/Ni becaus...

Ceramic/metal nanocomposite data reveals patterns which suggest that geometry plays an important role when sintering nanocomposites and gives information about the obtainable particle size of the second phase nanoparticles regardless of sintering method. Data suggests that matrix particle size plays the key role governing the lower boundary of obta...
