Seeing the invisible: Visible light superlens made from nanobeads: New solid 3-D superlenses extends magnification x5 to reveal new detail

A paper in Science Advances (12 August) provides proof of a new concept, using new solid 3D superlenses to break through the scale of things previously visible through a microscope.

Kepler Watches Stellar Dancers in the Pleiades Cluster.

Like cosmic ballet dancers, the stars of the Pleiades cluster are spinning. But these celestial dancers are all twirling at different speeds. Astronomers have long wondered what determines the rotation rates of these stars.

NREL technique leads to improved perovskite solar cells

The research, funded by the U.S. Department of Energy SunShot Initiative, involved hybrid halide perovskite solar cells and revealed treating them with a specific solution of methyl ammonium bromide (MABr) would repair defects, improving efficiency....

Cement design should take into account the water confined in the smallest pores: A researcher at the UPV/EHU-University of the Basque Country is participating in the study of the stresses of confined water in the micropores of cement at extreme temperatur

These variations in humidity and temperature are translated into physical processes involving evaporation or freezing of the water contained in the cement paste, which often cause stresses and even micro-cracking inside the cement. Characterizing the...
