    An international team has developed inks made of graphene-like materials for inkjet printing. New black phosphorus inks are compatible with conventional inkjet printing techniques for optoelectronics and photonics. Black phosphorus is a particularly interesting post-graphene nanomaterial for next generation devices. Yet despite remarkable performance in the lab, practical real-world exploitation of this material has been hindered by complex material fabrication and its poor environmental stability.

    Potential applications include durable tires, wearable electronics, medical devices. Imagine a tire that could heal after being punctured or a rubber band that never snapped. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new type of rubber that is as tough as natural rubber but can also self-heal.

    Self-healing materials aren’t new – researchers at SEAS have developed self-healing hydrogels, which rely on water to incorporate reversible bonds that can promote healing...

    Supermassive black holes feed on Cosmic Jellyfish

    August 17, 2017, Categories  Astronomy/Space

    Observations of 'Jellyfish galaxies' with ESO's Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly. This picture of one of the galaxies, nicknamed JO204, from the MUSE instrument on ESO's Very Large Telescope in Chile, shows clearly how material is streaming out of the galaxy in long tendrils to the lower-left. Red shows the glow from ionised hydrogen gas and the whiter regions are where most of the stars in the galaxy are located. Some more distant galaxies are also visible.

    Cosmic Magnifying Lens reveals Inner Jets of Black Holes

    August 17, 2017, Categories  Astronomy/Space

    Illustration shows a likely configuration of a gravitational lensing system discovered by OVRO. The 'milli-lens' is located in or near the intervening spiral galaxy. The lens is magnifying blobs of jet material within the active galaxy PKS1413+135, but the blobs are too small to be seen in the radio image (top left), taken by MOJAVE. Only when the blobs move far away from the yellow core do they expand and are visible as the pink blobs in the image. Credit: Anthony Readhead/Caltech/MOJAVE
