A downward buoyant force experiment

Revista Brasileira de Ensino de Física
In hydrostatics, the Archimedes principle predicts an upward force whenever a body is submerged in a liquid. In contrast to common sense, this physical law is not free of exceptions, as for example when the body touches the container.

Wide Temperature Zero Thermal Expansion in Al Matrix Composites with High Thermal Conductivity

Advanced Science, EarlyView.
Strain engineering strategy is implemented on the negative thermal expansion (NTE) phase Zn1.6Mg0.4P2O7 within composites, where Al matrix‐induced compressive strain drives uniform polyhedral and unit cell evolution, thereby enabling broad and consistent thermal compensation efficacy and obtaining good thermal performance.
