SPECIAL REPORT: Defense Community Slow to Grasp Potential of Quantum-Based Devices
Posted by Klaus Baldauf in categories: materials, quantum physics
CHICAGO — Four stories underground — encased in several feet of concrete — is the University of Chicago’s new nanofabrication facility, where researchers apply the principles of quantum physics to real-world problems and technologies.
A small cadre of faculty and graduate students in a clean room bathed in yellow light wear protective clothing to ensure the integrity of the experiments they are conducting, which involves the very matter that comprise the universe: electrons, photons, neutrons and protons.
The William Eckhardt Research Center where they are working is located across the street from where a team led by Enrico Fermi, the architect of the nuclear age, carried out the first self-sustaining nuclear reaction.

Dead whale found with 88 pounds of plastic in stomach in the Philippines
Posted by Xavier Rosseel in categories: government, materials
Messed up is the right phrasing for it, I figure.
March 18 (UPI) — After a dead whale washed ashore in the Philippines, scientists pulled 88 pounds of plastic debris from the mammal’s intestines. The young Cuvier’s beaked whale died from gastric shock, according to biologists.
The necropsy was conducted by scientists at the D’ Bone Collector Museum. They were assigned by biologists with the Philippines Bureau of Fisheries and Aquatic Resources.

Research set to shake up space missions
Posted by Caycee Dee Neely in categories: materials, space
New 2D materials research shows their capacity to survive and work well in the environment of space.
A new study from The Australian National University (ANU) has found a number of 2D materials can not only withstand being sent into space, but potentially thrive in the harsh conditions.

Ultrathin and ultrafast: Scientists pioneer new technique for two-dimensional material analysis
Posted by Quinn Sena in categories: materials, particle physics
Discovery allows scientists to look at how 2-D materials move with ultrafast precision.
Using a never-before-seen technique, scientists have found a new way to use some of the world’s most powerful X-rays to uncover how atoms move in a single atomic sheet at ultrafast speeds.
The study, led by researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and in collaboration with other institutions, including the University of Washington and DOE’s SLAC National Accelerator Laboratory, developed a new technique called ultrafast surface X-ray scattering. This technique revealed the changing structure of an atomically thin two-dimensional crystal after it was excited with an optical laser pulse.

Breakthrough process welds metal and glass together using ultrafast lasers
Posted by Quinn Sena in categories: innovation, materials
Traditionally, welding has been limited to materials that share similar properties, so it’s tough to make even aluminum and steel join forces. But now, scientists from Heriot-Watt University are claiming a breakthrough method that can weld together materials as different as glass and metal, thanks to ultrafast laser pulses.

Chirality yields colossal photocurrent
Posted by Quinn Sena in categories: biotech/medical, materials
A recently discovered Weyl semimetal delivers the largest intrinsic conversion of light to electricity of any material, an international team lead by a group of Boston College researchers reports today in the journal Nature Materials.
The discovery is based on a unique aspect of the material where electrons can be separated by their chirality, or handedness—similar to DNA. The findings may offer a new route to efficient generation of electricity from light, as well as for thermal or chemical sensing.
“We discovered that the Weyl semimetal Tantalum Arsenide, has a colossal bulk photovoltaic effect—an intrinsic, or non-linear, generation of current from light more than ten times larger than ever previously achieved,” said Boston College Associate Professor of Physics Kenneth Burch, a lead author of the article, titled “Colossal mid-infrared bulk photovoltaic effect in a type-I Weyl semimetal.”

Smart material made from squid teeth a potential plastic alternative
Posted by Genevieve Klien in category: materials
A newly-discovered material made from squid teeth could one day replace man-made fibres like nylon and polyester, according to a review by scientists at Pennsylvania State University. This would help to reduce microplastic pollution in the oceans, as well as paving the way for new possibilities such as self-repairing safety clothing, or garments with built-in, flexible screens.

Researchers develop fire-retardant coating featuring renewable materials
Posted by James Christian Smith in category: materials
Texas A&M University researchers are developing a new kind of flame-retardant coating using renewable, nontoxic materials readily found in nature, which could provide even more effective fire protection for several widely used materials.
