New method monitors semiconductor etching as it happens—with light
(Phys.org)—University of Illinois researchers have a new low-cost method to carve delicate features onto semiconductor wafers using light – and watch as it happens.
Transparent polymeric films with near-uniform, continuous nanoprotrusions show high water pinning abilities
A*STAR researchers have used nanoimprinting methods to make patterned polymeric films with surface topography inspired by that of a rose petal, producing a range of transparent films with high water pinning ...
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.
Packing the ions: Discovery boosts supercapacitor energy storage
Flat is in the eye of the beholder. When you're talking about nanomaterials, however, that eye is pretty much useless unless it's looking through an electron microscope or at a computer visualization. Yet ...
Researchers discover the cause of irradiation-induced instability in materials surfaces
A new discovery about the dynamic impact of individual energetic particles into a solid surface improves our ability to predict surface stability or instability of materials under irradiation over time.
Rethinking surface tension
(Phys.org) —If you've ever watched a drop of water form into a bead or a water strider scoot across a pond, you are familiar with a property of liquids called surface tension.
The effect of climate change on iceberg production by Greenland glaciers
While the impact of climate change on the surface of the Greenland ice sheet has been widely studied, a clear understanding of the key process of iceberg production has eluded researchers for many years. Published ...
New theory for magnetic stripes on Mars
Geoscientists discover trigger for past rapid sea level rise
The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models.
A Hidden Drip, Drip, Drip Beneath Earth's Surface
(PhysOrg.com) -- There are very few places in the world where dynamic activity taking place beneath Earth's surface goes undetected.
Studying permafrost soil, above and below ground: Research could lead to a better understanding of the Arctic ecosystem
(Phys.org)—What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change? It's part of a new way to explore the little-known world of permafrost ...
Cooler waters help diminish Isaac's punch
(Phys.org)—Seven years after the powerful Category 3 Hurricane Katrina caused widespread devastation along the Gulf Coast, a Category 1 Hurricane Isaac, with maximum sustained winds of 80 miles per hour ...
Analyzing the status of oxide surface photochemical reactivity
As shown by Pacific Northwest National Laboratory's Dr. Michael Henderson and Dr. Igor Lyubinetsky in their invited review article, using scanning probe microscopy techniques, in particular scanning tunneling microscopy or ...
Dawn mission video shows Vesta's coat of many colors
(Phys.org) -- A new video from NASA's Dawn mission reveals the dappled, variegated surface of the giant asteroid Vesta. The animation drapes high-resolution false color images over a 3-D model of the Vesta ...
