A NIST-developed nanofluidic device separates and measures nanoparticles of different sizes, offering a faster and more economical approach to nanoparticle sample preparation. The device's tailored resolution and surface chemistry enable the sorting of complex nanoparticle mixtures.
UK researchers have discovered electrically charged ash in the plume of Iceland's Eyjafjallajokull volcano. The finding contradicts models and adds a new dimension to understanding volcanic plumes' impact on air travel. Detailed measurements reveal self-renewing charge within the plume, which affects particle behavior and growth.
Researchers at the University of Illinois at Urbana-Champaign have created polarized Janus particles that spontaneously self-assemble into clusters with specific shapes and distributions of electric charge. The clusters can exhibit unique properties, such as a flywheel-like shape that can revolve around a polar axle.
Jeanne E. Pemberton's research reveals that changing the electrical charge on electronic paper affects how well ink sticks, enabling the development of reusable tablets. The study uses the 'emersion' method to analyze molecular interactions at the interface between liquids and solids.
A University of Colorado Boulder research team has confirmed a theory about charged dust in space, explaining how it affects spacecraft and astronauts. The study used an experiment to levitate particles with positive charge above the moon's surface.
Researchers used angle-resolved photoemission spectroscopy to study the electronic structure of Nd-LSCO, finding charge carriers segregated into one-dimensional lines and exhibiting quantum fluctuations that give rise to two-dimensional effects. This discovery may help resolve a paradox between different theories of superconductivity.
Researchers at Max Planck Institute for Quantum Optics found that molecular clusters break up into positively and negatively charged fragments upon impact with any solid surface. They propose that neutral alkali atoms play a key role in charge separation, leading to the formation of separate ionic fragments.
Scientists discover that in complex systems like living cells, opposite charges don't always attract, but instead repel or separate into adhesive zones. This understanding can lead to designing new drug carriers and smart materials that respond to their environment.
Researchers discovered a new class of microstructured materials that self-assemble into flat, two-dimensional crystallites made from tiny plastic beads. Under the right conditions, these beads seem to defy the basic physical principle of oppositely charged objects attracting.
In an experiment, Weizmann Institute scientists succeeded in measuring the smallest electronic charge, equal to one-fifth the charge of a single electron. This measurement was made using a different electronic system, proving that it refers solely to the electronic charge itself.
Researchers have developed a theory to explain the sudden change of rare earth mirror materials into transparent windows when exposed to hydrogen. This phenomenon has potential applications in smart windows for energy savings.
Researchers at Purdue University have discovered that the electron's electromagnetic force may not be constant but rather increases towards the central core. The discovery reveals a cloud of virtual particles surrounding the core, which affects how we perceive the electromagnetic force from the electron.
A new study led by a University of Colorado astrophysicist suggests that dust grains dominating Jupiter's peculiar ring may have lifetimes of just hours or days. The study indicates the swelling of the inner ring is caused by positive electrical charges on the dust grains resulting from solar radiation.
