Why seashells' mineral forms differently in seawater

For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth's oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take the form of calcite, ...

Team reveals molecular structure of water at gold electrodes

When a solid material is immersed in a liquid, the liquid immediately next to its surface differs from that of the bulk liquid at the molecular level. This interfacial layer is critical to our understanding of a diverse set ...

New evidence for oceans of water deep in the Earth

Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form—the ingredients for ...

Moth-inspired nanostructures take the color out of thin films

Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" ...

Nanosuits help small creatures survive a vacuum

(Phys.org) —Scientists use scanning electron microscopes (SEMs) to study tiny structures in small organisms. SEMs can only work in a high vacuum, and exposure to such a vacuum normally causes living things to die very ...

Research show mechanism behind wear at the atomic scale

(Phys.org)—Wear is a fact of life. As surfaces rub against one another, they break down and lose their original shape. With less material to start with and functionality that often depends critically on shape and surface ...
