Bacterial adhesive is 2-3 times stronger than common commercial glues
The glue one species of water-loving bacteria uses to grip its surroundings may be the strongest natural adhesive known to science. If engineers can find a way to mass-produce the material, it could have uses in medicine, marine technology and a range of other applications.
Researchers at Indiana University in Bloomington and Brown University in Providence, R.I., studied how much force they needed to tug the tiny, stalked Caulobacter crescentus off a glass plate. As the researchers reported in the Apr. 11, 2006, Proceedings of the National Academy of Sciences, the bacteria grip with a force of 70 newtons per square millimeter--roughly 5 tons per square inch--or equivalent to the downward force exerted by three cars balancing on a spot the size of a quarter. While the researchers do not yet know if the substance is the strongest glue on Earth, it is stronger than cyanoacrylate superglues found on store shelves and may be rivaled only by a few synthetics.

InLight study: insights into chemical processes using light

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,...
