Nanoscale luminescent force sensors excel at measuring piconewton forces, while larger sensors have proven powerful in probing micronewton forces. However, large gaps remain in the force ...

Two studies show that the light emitted by nanocrystals embedded with luminescent ions can be used to sense forces with high spatial resolution — even when those forces are inside a microscopic ...

U.S. hotel occupancy rates in 2024 are lower than pre-pandemic levels, with an average of 63.9% compared to 66.9% in 2019. The growth of hotel supply and changes in corporate travel patterns ...
