A new National Institute of Standards and Technology (NIST) project aims to stir up materials research by adapting "lab-on-a-chip" technology to mix and evaluate experimental concoctions at a rapid clip, hastening improvements in products ranging from paints to shampoos to plastics.
Initially, researchers at the NIST Combinatorial Methods Center (NCMC) and several of the NCMCs company members plan to rev up the search for new or better emulsions--often-complex formulations that are the basis for U.S. product markets totaling more than $50 billion. They will start by deciphering interactions at the interfaces (inter-facial tension) between the various components that make up these viscous mixtures and are key to their performance.
Now, efforts to improve paints, shampoos and other emulsions tend to be time-consuming, trial-and-error exercises. But with tiny "lab-on-chip" devices, much of the process can be automated, permitting rapid, systematic testing of new material formulations.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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:...

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...
