New research unlocks the mystery of New England's beaches

Millions of Americans will visit New England's beaches this summer to cool off, play in the waves and soak up the sun. Until now, the factors governing which beaches slope gradually to the sea and which ones end abruptly ...

New technique builds super-hard metals from nanoparticles

Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal's grain structure—the microscopic ...

Soil data reveals secrets in ancient Israel

Fresh insight gleaned from rocks and soil mapped across Israel will help reveal more information about ancient humans, animals and evolution in the Middle East region.

Going super small to get super strong metals

You can't see them, but most of the metals around you—coins, silverware, even the steel beams holding up buildings and overpasses—are made up of tiny metal grains. Under a powerful enough microscope, you can see interlocking ...

Grain boundaries in graphene do not affect spin transport

Researchers from the ICN2 Theoretical and Computational Nanoscience Group as well as the Université catholique de Louvain have used numerical simulations to show that spin diffusion length is independent of grain size. The ...

Lead halide perovskites are not ferroelectric

In a solar cell, when the sunlight impacts the material, a charge is generated. Specifically, this charge corresponds to an electron-hole pair, where an electron is excited to the conduction band, leaving a hole in the valence ...
