Published Arrays of quantum rods could enhance TVs or virtual reality devices


Using scaffolds of folded DNA, engineers assembled arrays of quantum rods with desirable photonic properties that could enable them to be used as highly efficient micro-LEDs for televisions or virtual reality devices.
Published Quantum material exhibits 'non-local' behavior that mimics brain function


New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Single drop of ethanol to revolutionize nanosensor manufacture


Engineers have developed a breakthrough technique to make the processing of nanosensors cheaper, greener and more effective by using a single drop of ethanol to replace heat processing of nanoparticle networks, allowing a wider range of materials to be used to make these sensors.
Published Current takes a surprising path in quantum material


Researchers used magnetic imaging to obtain the first direct visualization of how electrons flow in a special type of insulator, and by doing so they discovered that the transport current moves through the interior of the material, rather than at the edges, as scientists had long assumed.
Published Sensing and controlling microscopic spin density in materials


Researchers found a way to tune the spin density in diamond by applying an external laser or microwave beam. The finding could open new possibilities for advanced quantum devices.
Published Quantum discovery: Materials can host D-wave effects with F-wave behaviors


In a potential boon for quantum computing, physicists have shown that topologically protected quantum states can be entangled with other, highly manipulable quantum states in some electronic materials.
Published Thermal imaging innovation allows AI to see through pitch darkness like broad daylight


Engineers have developed HADAR, or heat-assisted detection and ranging.
Published How heat treatment affects a milk alternative made from rice and coconut water


Whether they're made from soybeans, almonds, oats, or just sourced straight from the cow, milk products must go through heat treatment to prevent harmful bacterial growth and keep them safe. But understanding how these processes affect new, plant-based milk formulations could make the beverages more pleasant to drink as well. Researchers have discovered how pasteurization and sterilization affects the look and feel of one such drink made from coconut and rice.
Published Scientists create novel approach to control energy waves in 4D


Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.
Published When electrons slowly vanish during cooling


Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.
Published Way cool: 'freeze ray' technology


An unusual discovery is now being developed as an on-demand cooling solution for high-flying military electronics.
Published Fusion model hot off the wall


Heat load mitigation is critical to extending the lifetime of future fusion device. Researchers have found a way to explain the rotational temperatures measured in three different experimental fusion devices in Japan and the United States. Their model evaluates the surface interactions and electron-proton collisions of hydrogen molecules.
Published A new type of quantum bit in semiconductor nanostructures


Researchers have created a quantum superposition state in a semiconductor nanostructure that might serve as a basis for quantum computing. The trick: two optical laser pulses that act as a single terahertz laser pulse.
Published Novel thermal sensor could help drive down the heat


Excess heat from electronic or mechanical devices is a sign or cause of inefficient performance. In many cases, embedded sensors to monitor the flow of heat could help engineers alter device behavior or designs to improve their efficiency. For the first time, researchers exploit a novel thermoelectric phenomenon to build a thin sensor that can visualize heat flow in real time. The sensor could be built deep inside devices where other kinds of sensors are impractical. It is also quick, cheap and easy to manufacture using well-established methods.
Published Catalyst can control methane emissions in natural gas engines


A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the advance in single atom catalysis has the potential to lower exhaust emissions of methane, one of the worst greenhouse gases that traps heat at about 25 times the rate of carbon dioxide. Researchers showed that the single-atom catalyst was able to remove methane from engine exhaust at lower temperatures, less than 350 degrees Celsius (662 degrees Fahrenheit), while maintaining reaction stability at higher temperatures.
Published A non-covalent bonding experience


Putting a suite of new materials synthesis and characterization methods to the test, a team of scientists has developed 14 organic-inorganic hybrid materials, seven of which are entirely new.
Published Droplet levitation is a new way to explore airborne viruses and microorganisms


Researchers report achieving self-sustaining and long-term levitation of millimeter-sized droplets of several different liquids without any external forces. To get the droplets to levitate, they use solutocapillary convection, which occurs when a surface tension gradient is formed by nonuniform distribution of vapor molecules from the droplet at the pool surface. Further exploring the effects of various external conditions on self-sustained droplet levitation will reveal whether it can be harnessed and adapted for microbiology and biochemistry applications.
Published Researchers establish criterion for nonlocal quantum behavior in networks


A new theoretical study provides a framework for understanding nonlocality, a feature that quantum networks must possess to perform operations inaccessible to standard communications technology. By clarifying the concept, researchers determined the conditions necessary to create systems with strong, quantum correlations.
Published Small-winged and lighter colored butterflies likely to be at greatest threat from climate change


Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.
Published New superconductors can be built atom by atom


The future of electronics will be based on novel kinds of materials. Sometimes, however, the naturally occurring topology of atoms makes it difficult for new physical effects to be created. To tackle this problem, researchers have now successfully designed superconductors one atom at a time, creating new states of matter.
