Effect of calcium sulfoaluminate in fly ash–metakaolin blended binders on hydration and mechanical properties

Advancements in sustainable cement technology rely on the use of supplementary cementitious materials to enhance performance and reduce environmental impact. Mineral additives such as fly ash (FA), blast-furnace slag, silica fume and limestone are commonly used to lower clinker c...

Design principle for mitigating moisture-induced degradation in 2D halide perovskites

We establish a conceptual framework which explains and mitigates moisture-induced degradation in 2D perovskites. Degradation proceeds along defined pathways across the spacer cation iodide (A′I or A′I2)-PbI2-H2O ternary phase diagram as moisture intercalates into the perovskite....

Nonlocal Hamilton–Jacobi Equations on a network with Kirchhoff type conditions

In this article, we consider nonlocal Hamilton–Jacobi Equations on networks with Kirchhoff type conditions for the interior vertices and Dirichlet boundary conditions for the boundary ones: we provide general existence and comparison results in the case when the nonlocal operator...

How Does Motion-to-Photon Latency Influence the Perception-Action Loop

The perception-action loop plays an essential role in sports performance. Virtual reality is increasingly used to train this loop because it provides a controlled setting. However, motion-to-photon latency, the delay between the user’s real and virtual motion, may disrupt user ex...
