Residual stresses in ceramic metal assembly after brazing process [PDF]
The framework of this study is the thermo-mechanical analysis of the brazing process of ceramic metal assemblies. The thermal expansion gradient between ceramic and metallic materials leads to the development of residual stresses during the cooling phase

Precise Manipulation of Amino Groups in Zr-MOFs for Efficient Adsorption Performance
Developing high-performance adsorbents for heavy metal (Cr (VI)) removal is essential for sustainable environments, but it is still challenging. Herein, a simple solvothermal method was proposed to fabricate Zr-MOFs (UiO-66), which was innovatively ...

Ceramic materials lead to underestimated DNA quantifications : a method for reliable measurements [PDF]
In the context of investigating cell-material interactions or of material-guided generation of tissues, DNA quantification represents an elective method to precisely assess the number of cells attached or embedded within different substrates. Nonetheless,

The numerical analysis of dynamically loaded ceramic: a crack softening approach [PDF]
A physically based crack softening approach to modelling the failure of brittle materials that have been subjected to dynamic loading is presented and applied to a two-dimensional non-linear transient dynamic hydrocode.

Measuring the strength of brittle materials by depth-of-penetration testing [PDF]
Based on an energy conservation model, the strength offered by a number of brittle materials has been calculated from depth-of-penetration (DOP) test results. Each material was completely penetrated by a tungsten carbide cored projectile of known kinetic
