Researchers print rainbow colorants on shimmering chocolate

Posted by in categories: food, materials

ETH researchers are making chocolates shimmer in rainbow colors without the addition of colorants. They have found a way to imprint a special structure on the surface of the chocolate to create a targeted color effect.

Traditional methods for coloring have been around for a long time. But the ETH researchers are able to create the rainbow effect without artificial colorants. The effect is achieved simply through a surface imprint that produces what the scientists refer to as a structural color. The process is similar to a chameleon, whose skin surface modulates and disperses light to display specific colors.

New Neutron Detector Can Fit in Your Pocket – Critical for Catching Smuggled Nuclear Materials

Posted by in categories: materials, security

Homeland Security might soon have a new tool to add to its arsenal.

Researchers at Northwestern University and Argonne National Laboratory have developed a new material that opens doors for a new class of neutron detectors.

With the ability to sense smuggled nuclear materials, highly efficient neutron detectors are critical for national security. Currently, there are two classes of detectors which either use helium gas or flashes of light. These detectors are very large — sometimes the size of a wall.

For The First Time, Physicists Have Achieved Superconductivity at Room Temperature

Posted by in categories: materials, physics

A major new milestone has just been achieved in the quest for superconductivity. For the first time, physicists have achieved the resistance-free flow of an electrical current at room temperature — a positively balmy 15 degrees Celsius (59 degrees Fahrenheit).

This has smashed the previous record of −23 degrees Celsius (−9.4 degrees Fahrenheit), and has brought the prospect of functional superconductivity a huge step forward.

NASA is getting ready to land on an asteroid that may hold the building blocks of life

Posted by in categories: materials, space

With NASA getting ready to land a spacecraft on the asteroid Bennu in just a few short days, the mysterious space rock is already revealing some of its secrets, including the presence of carbon-bearing materials.

Several studies were published on the matter in the journals Science and Science Advances, noting that carbon-bearing, organic material is “widespread” on the surface of the asteroid. This includes the area where NASA’s OSIRIS-REx spacecraft will take its first sample from, known as Nightingale, on Oct. 20.

“The abundance of carbon-bearing material is a major scientific triumph for the mission. We are now optimistic that we will collect and return a sample with organic material – a central goal of the OSIRIS-REx mission,” said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona in Tucson, in a statement.

New Wearables Can Be Printed Directly Onto Skin

Colder, Colder…

The process of sintering, or bonding the metals that make up the flexible circuits, usually happens at 572 degrees Fahrenheit.

“The skin surface cannot withstand such a high temperature, obviously,” Penn State engineer and lead author Hanyu “Larry” Cheng said in a press release. “To get around this limitation, we proposed a sintering aid layer — something that would not hurt the skin and could help the material sinter together at a lower temperature.”

Stacking and twisting graphene unlocks a rare form of magnetism

Posted by in categories: materials, particle physics

Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity.

Now, a team of researchers at Columbia University and the University of Washington has discovered that a variety of exotic electronic states, including a rare form of magnetism, can arise in a three-layer structure.

The findings appear in an article published Oct. 12 in Nature Physics.
