Using direct-write assembly of organic ink, researchers at the University of Illinois at Urbana-Champaign have developed a technique for fabricating three-dimensional microvascular networks. These tiny networks could function as compact fluidic factories in miniature sensors, chemical reactors, or computers used in applications from biomedicine to information technology.
"The fabrication technique produces a pervasive network of interconnected cylindrical channels, which can range from 10 to 300 microns in diameter," said Jennifer Lewis, a professor of materials science and engineering and of chemical engineering at Illinois. "Our approach opens up new avenues for device design that are currently inaccessible by conventional lithographic methods."
The microvascular networks also could be combined with self-healing functionality, "providing an analog to the human circulatory system for the next generation of autonomous healing materials," said Scott White, a professor of aeronautical and astronautical engineering and a researcher at the Beckman Institute for Advanced Science and Technology. "The embedded network would serve as a circulatory system for the continuous transport of repair chemicals to sites of damage within the material."

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:...
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...
