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 ...
Graphene nanoribbons grow due to domino-like effect
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 ...
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 ...
Researchers find cicada wing structure able to kill bacteria on contact (w/ video)
Researchers create super-repellant surface material (w/ video)
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 ...
Just add water: 3-D silicon shapes fold themselves when wetted by microscopic droplets
Researchers from the University of Twente in the Netherlands have taken the precise art of origami down to the microscopic scale. Using only a drop of water, the scientists have folded flat sheets of silicon ...
Nanosuits help small creatures survive a vacuum
Researchers create 'nanoflowers' for energy storage, solar cells
(Phys.org)—Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous ...
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 ...
Human eye inspires clog-free ink jet printer invention
Clogged printer nozzles waste time and money while reducing print quality. University of Missouri engineers recently invented a clog-preventing nozzle cover by mimicking the human eye.
Research: Graphene grows better on certain copper crystals
New observations could improve industrial production of high-quality graphene, hastening the era of graphene-based consumer electronics, thanks to University of Illinois engineers.
GRAIL creates most accurate Moon gravity map (w/ video)
(Phys.org)—Twin NASA probes orbiting Earth's moon have generated the highest resolution gravity field map of any celestial body.
