Record-breaking Terahertz Laser Beam
Record-breaking Terahertz Laser Beam
A new, extremely efficient source of terahertz radiation has been developed at TU Wien (Vienna): Lasers turn air into plasma, thereby producing terahertz rays for many possible applications. Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry.

A New Look at
A New Look at "Strange Metals"
For years, a new synthesis method has been developed at TU Wien (Vienna) to unlock the secrets of "strange metals". Now a breakthrough has been achieved. The results have been published in "Science". Superconductors allow electrical current to flow without any resistance - but only below a certain critical temperature.

Finds billions of quantum entangled electrons in 'strange metal'
Finds billions of quantum entangled electrons in ’strange metal’
Physicists provide direct evidence of entanglement's role in quantum criticality In a new study, U.S. and Austrian physicists have observed quantum entanglement among "billions of billions” of flowing electrons in a quantum critical material. The research, which appears this week in Science, examined the electronic and magnetic behavior of a "strange metal” compound of ytterbium, rhodium and silicon as it both neared and passed through a critical transition at the boundary between two well-studied quantum phases.

Researchers break the geometric limitations of moiré pattern in graphene heterostructures
Researchers at the University of Manchester in collaboration with CMT theorists (M. Andelkovic, S. Milovanovic, L. Covaci and F. Peeters) have uncovered interesting phenomena when multiple two-dimensional materials are combined into van der Waals heterostructures (layered 'sandwiches' of different materials).

A new approach to making airplane parts, minus the massive infrastructure
A new approach to making airplane parts, minus the massive infrastructure
Carbon nanotube film produces aerospace-grade composites with no need for huge ovens or autoclaves. A modern airplane's fuselage is made from multiple sheets of different composite materials, like so many layers in a phyllo-dough pastry. Once these layers are stacked and molded into the shape of a fuselage, the structures are wheeled into warehouse-sized ovens and autoclaves, where the layers fuse together to form a resilient, aerodynamic shell.

An 18-carat gold nugget made of plastic
An 18-carat gold nugget made of plastic
ETH researchers have created an incredibly lightweight 18-carat gold, using a matrix of plastic in place of metallic alloy elements. Lovers of gold watches and heavy jewellery will be thrilled. The objects of their desire may someday become much lighter, but without losing any of their glitter. Especially with watches, a small amount of weight can make all the difference.

Bandage material helps stop bleeding without adhering to the wound
Bandage material helps stop bleeding without adhering to the wound
Researchers from ETH Zurich and the National University of Singapore have developed a new kind of bandage that helps blood to clot and doesn't stick to the wound. This marks the first time that scientists have combined both properties in one material. "We did not actually plan this, but that is just how science works sometimes: you start researching one thing and end up somewhere else," says ETH Professor Dimos Poulikakos.

Early humans optimised stone tool use at Tanzania’s Olduvai Gorge
Early Stone Age populations living up to 1.8 million years ago made complex decisions in selecting different types of stone to optimise a variety of cutting tools, according to a new study by UCL, University of Kent and the Centre for Human and Social Sciences, Spain. The study, published in the Journal of Royal Society Interface , offers new insight into the complexity of stone tool use, design and production.

Materials ’remember’ past stresses as they age
A new study by University of Chicago and University of Pennsylvania scientists shows that as materials age, they 'remember' prior stresses and external forces, which researchers can then use to create new materials with unique properties.    The study, published Dec. 20 in  Science Advances , found that certain types of materials have a "memory" of how they were processed, stored, and manipulated.

How a ’vegetable ion’ helped scientists unlock theory behind transitions of materials
A puddle freezing on the sidewalk, your humidifier pumping out water vapor, salt trucks melting icy streets-wintertime in Chicago is full of examples of a physics phenomenon called a "phase transition," in which a material changes state. Physicists are fascinated by this phenomenon, which is useful in technology from the basic steam turbine all the way to MRIs.   In a paper published Dec.

New archaeological discoveries reveal birch bark tar was used in medieval England
New archaeological discoveries reveal birch bark tar was used in medieval England
Scientists from the University of Bristol and the British Museum, in collaboration with Oxford Archaeology East and Canterbury Archaeological Trust, have, for the first time, identified the use of birch bark tar in medieval England - the use of which was previously thought to be limited to prehistory.

Skin and Mucous Membrane Lesions as Complication of Pneumonia
Skin and Mucous Membrane Lesions as Complication of Pneumonia
Painful inflammatory lesions of the skin and mucous membranes may occur in children who develop bacterial pneumonia. A research group at the University Children's Hospital Zurich has recently developed a new diagnostic blood test, which reliably diagnoses bacteria as the causative pathogen at an early stage, allowing more specific treatment and prediction about prognosis.

Making chocolate colourful
Making chocolate colourful
ETH researchers are making chocolates shimmer in rainbow colours without the addition of colourants. They have found a way to imprint a special structure on the surface of the chocolate to create a targeted colour effect.

New coating hides temperature change from infrared cameras
An ultrathin coating developed by University of Wisconsin-Madison engineers upends a ubiquitous physics phenomenon of materials related to thermal radiation: The hotter an object gets, the brighter it glows. The new coating - engineered from samarium nickel oxide, a unique tunable material - employs a bit of temperature trickery.

How Electrons Break the Speed Limit
In work that may have broad implications for the development of new materials for electronics, Caltech scientists for the first time have developed a way to predict how electrons interacting strongly with atomic motions will flow through a complex material. To do so, they relied only on principles from quantum mechanics and developed an accurate new computational method.

Gaining insight into the energy balance of earthquakes
Researchers at EPFL's Computational Solid Mechanics Laboratory and the Weizmann Institute of Science have modeled the onset of slip between two bodies in frictional contact. Their work, a major step forward in the study of frictional rupture, could give us a better understanding of earthquakes - including how far and fast they travel.
