Observing individual atoms in 3D nanomaterials and their surfaces
Atoms are the basic building blocks for all materials. To tailor functional properties, it is essential to accurately determine their atomic structures. KAIST researchers observed the 3D atomic structure of a nanoparticle at the atom level via neural.....»»
Quality control: Neatly arranging crystal growth to make fine thin films
Table salt and refined sugar look white to our eyes, but that is only because their individual colorless crystals scatter visible light. This feature of crystals is not always desirable when it comes to materials for optical and electrical devices, h.....»»
Physicists develop new model that describes how filaments assemble into active foams
Many fundamental processes of life, and their synthetic counterparts in nanotechnology, are based on the autonomous assembly of individual particles into complex patterns. LMU physicist Professor Erwin Frey, Chair of Statistical and Biological Physic.....»»

Scientists equip Australian sea lions with cameras to explore previously unmapped ocean habitats
What lies deep beneath ocean surfaces is often a mystery. In Australia, many underwater habitats have not been mapped, and researchers know little about them. Now, scientists are working to change that by employing sea lions as videographers......»»
Nanomaterials may enhance plant tolerance to high soil salt levels
Soil salt concentrations above the optimal threshold for plant growth can threaten global food security by compromising agricultural productivity and crop quality. An analysis published in Physiologia Plantarum has examined the potential of nanomater.....»»
New computer vision-based system monitors seasonal dynamics of tropical water
Understanding how water moves and changes around the world is more important than ever due to climate change, but monitoring inland water in the tropics is not easy. Most satellites are optical and simply take photos of surfaces. They cannot see thro.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»

New perspectives for using corals in climate research
Ancient ocean temperatures are most commonly reconstructed by analyzing the ratio of different oxygen atoms in the calcium carbonate remains of fossils. However, this presents many challenges, including a combination of biological processes known as.....»»
Investigation into the regime between the nano- and microscale could pave the way for nanoscale technologies
In electronic technologies, key material properties change in response to stimuli like voltage or current. Scientists aim to understand these changes in terms of the material's structure at the nanoscale (a few atoms) and microscale (the thickness of.....»»
Breakthrough in Z-alkene synthesis: Scientists develop efficient and sustainable method
