Flexural Tests on Consolidation Effects on Stone [PDF]

, 2019
This paper describes laboratory verification tests for determining the efficiency of various consolidation treatments on Czech quartz sandstone. It compares material data acquired using circular discs and rectangular plates. While the application of rectangular plates enables the testing not only of strength but also of other material characteristics –

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Flexural Behavior of SFRC: Testing and Modeling [PDF]

Journal of Materials in Civil Engineering, 1999
In this paper the results of tests performed on specimens and structural elements made of steel fiber reinforced concrete (SFRC) are presented. Fiber content of the concrete ranged from 0 to 60 kg/m³. Using the results of the uniaxial compression tests performed under displacement control condition, a stress-strain relationship for fiber concrete in ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...
