Imagine an entire chemistry laboratory reduced to the size of a postage stamp. It could happen.
While others may think big, Texas A&M University physicists Don Naugle and co-worker Igor Lyuksyutov are thinking small - as in micro small. They have successfully managed to levitate micron-sized fluids using magnets, which could lead to new advances in medicine, chemistry, chemical engineering and other related fields. By using small magnets on a postage-stamp sized chip, Naugle and Lyuksyutov have managed to move and merge tiny levitating droplets and crystals and to control the orientation of the levitating crystals.
The droplets used were as small as bacteria or 100 times smaller than a human hair, and up to one billion times smaller in volume than has been demonstrated by conventional methods. Their work was recently published in Applied Physics Letter and featured in several science journals. Their research is funded by The Robert A. Welch Foundation and National Science Foundation grants. "It might be possible to do the same thing with a large number of fluids, chemicals or even a virus," Naugle explains.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
