Defects promise quantum communication through standard optical fiber

Posted by in categories: materials, quantum physics

An international team of scientists led by the University of Groningen’s Zernike Institute for Advanced Materials created quantum bits that emit photons that describe their state at wavelengths close to those used by telecom providers. These qubits are based on silicon carbide in which molybdenum impurities create color centers. The results were published in the journal npj Quantum Information on 1 October.

Fungus may be the key to colonizing mars

Posted by in categories: materials, space

The thought of colonizing Mars has science fiction aficionados, scientists, and billionaire entrepreneurs staring up at the night sky with renewed wonder and inspiration. But the key to achieving the lofty goal of colonizing and building extensively on a new planet may not exist out among the stars, but under our feet right here on Earth.

Christopher Maurer, an architect and Founder of Cleveland-based Redhouse Studio, and Lynn Rothschild, a NASA Ames researcher, believe algae and mycelium (the vegetative part of a fungus that consists of a network of fine white filaments) may make the perfect building material on Mars.

Spray-on antennae could usher in a generation of ultra-slim gadgets

Posted by in categories: engineering, materials

Researchers from Drexel University’s College of Engineering invented a material called MXene, that they say perform as well as those currently used in mobile devices.

MXene titanium carbide can be dissolved in water to create an ink or paint and the exceptional conductivity of the material enables it to transmit and direct radio waves, even when it’s applied in a very thin coating.

Mushrooms could solve the war on plastic, says Kew Gardens

Posted by in category: materials

Fungi could be the key to winning the war on plastic, leading scientists at Kew Gardens has said.

The first ever report on the state of the world’s fungi has today revealed that if the natural properties of fungus can be harnessed and developed, plastic could be broken down naturally in weeks rather than years.

Kew Gardens and a team of over 100 scientists from 18 countries have compiled the paper, which shows how different organisms can decompose plastics, clean up radioactive material and even speed up the production of biodiesel.

Artificial Retinas Made Of This Ultra-Thin Super Material Could Help Millions See Again

Posted by in categories: materials, particle physics

TRULY SUPER. There’s a reason researchers call graphene a “super material.” Even though it’s just a single layer of carbon atoms thick, it’s super strong, super flexible, and super light. It also conducts electricity, and is biodegradable. Now an international team of researchers has found a way to use the super material: to create artificial retinas.

They presented their work Monday at a meeting of the American Chemical Society (ACS).

ARTIFICIAL RETINAS. The retina is the layer of light-sensitive cells at the back of the eye responsible for converting images into impulses that the brain can interpret. And without a functional one, a person simply can’t see.

Graphene enables clock rates in the terahertz range

Posted by in categories: materials, particle physics

Graphene — an ultrathin material consisting of a single layer of interlinked carbon atoms — is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today’s silicon-based electronics. Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P), have now shown for the first time that graphene can actually convert electronic signals with frequencies in the gigahertz range — which correspond to today’s clock rates — extremely efficiently into signals with several times higher frequency. The researchers present their results in the scientific journal Nature.
