'Shadow waveguide' casts complex acoustic patterns to control particles

Engineers at Duke University have devised a new approach to using sound waves to manipulate tiny particles suspended in liquid in complex ways. Dubbed a "shadow waveguide," the technique uses only two sound sources to create a tightly confined, spatially complex acoustic field inside a chamber without requiring any interior structure. The technology offers a new suite of features to the fast-developing platform of acoustic tweezers that has applications in fields such as chemical reaction control, micro-robotics, drug delivery, and cell and tissue engineering.

High-speed camera captures a water jet's splashy impact as it pierces a droplet

Squirting a jet of water through a drop of liquid may sound like idle fun, but if done precisely, and understood thoroughly, the splashy exercise could help scientists identify ways to inject fluids such as vaccines through skin without using needles.

Exploring how tantalum behaves at high pressures and temperatures

Lawrence Livermore National Laboratory (LLNL) researchers have explored high-pressure behavior of shock-compressed tantalum at the Omega Laser Facility at the University of Rochester's Laboratory for Laser Energetics (LLE). The work showed tantalum did not follow the predicted phase changes at high pressure and instead maintained the body-centered cubic (BCC) phase until melt.

Two-dimensional supersolid quantum gas produced in the laboratory for the first time

Quantum matter can be solid and fluid at the same time—a situation known as supersolidity. Researchers led by Francesca Ferlaino have now created for the first time this fascinating property along two dimensions. They now report in the journal Nature on the realization of supersolidity along two axes of an ultracold quantum gas. The experiment offers many possibilities for further investigation of this exotic state of matter.

Experimental confirmation of wave-particle duality

The 21st century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early 20th century and has been used to develop unprecedented technologies which include quantum information, quantum communication, quantum metrology, quantum imaging, and quantum sensing. However, in quantum science, there are still unresolved and even inapprehensible issues like wave-particle duality and complementarity, superposition of wave functions, wave function collapse after quantum measurement, wave function entanglement of the composite wave function, etc.

A new type of super-resolution chemical microscopy

Conventional experiments in chemistry and biology study the behavior of the two, but it has been an abiding scientific challenge for scientists to observe, manipulate and measure the chemical reactions of individual molecules.

An emberometer could gauge the threat of wildfire-spreading embers

As wildfire fronts advance through landscapes or communities on the ground, they also attack from above, launching volleys of glowing embers into the air. Also known as firebrands, these specks of burning debris can glide for up to 40 kilometers (approximately 24 miles) before landing and can cause up to 90% of home and business fires during wildfires.

'Triangle singularity' is responsible for transformation in the particle zoo

An international study led by the University of Bonn has found evidence of a long-sought effect in accelerator data. The so-called "triangle singularity" describes how particles can change their identities by exchanging quarks, thereby mimicking a new particle. The mechanism also provides new insights into a mystery that has long puzzled particle physicists: Protons, neutrons and many other particles are much heavier than one would expect. This is due to peculiarities of the strong interaction that holds the quarks together. The triangle singularity could help to better understand these properties. The publication is now available in Physical Review Letters.

Nanostructure-based lasers for information and communication technologies

The internet of things (IoT) enables the interconnection and data transmission among a plethora of physical objects such as terminal devices, vehicles, and buildings that are embedded with electronics, software, sensors, actuators, and network connectivity. In 5G and 6G optical networks, high-speed and low-latency communications enable interconnection among a wide variety of endpoints through the IoT. Furthermore, quantum technologies are on the way to reshape the future of internet by providing considerably faster and largely more secure data transmission owing to new encryption protocols based on quantum laws. The rule of thumb of such key applications is that they all require the utilization of laser sources to perform complex tasks at ultra-fast speed and to enable broadband, secure and energy efficient communications.

CERN to provide second DUNE cryostat

Neutrinos are tricky beasts. Alone among known fundamental particles, they suffer from an identity crisis—if it were possible to put them on a weighing scale, you would unpredictably measure one of three possible masses. As a result, the three neutrino "flavors" merge into each other as they race through space and matter, opening up the potential for matter-antimatter asymmetries relevant to open questions in cosmology. Neutrinos are today the subject of a vibrant worldwide research program in particle physics, astrophysics and multi-messenger astronomy.

The secrets of perspective of Jan Van Eyck's paintings unveiled by computer vision

Perspective is the technique that enables objects to be represented in three dimensions on a flat surface by giving them an effect of depth. During the Renaissance, linear perspective revolutionized Italian painting, notably with Giotto and the notions of convergence points and the horizon line. In 1425, the architect Filippo Brunelleschi invented the first augmented reality device called Tavoletta, a wooden panel with an eyepiece. Finally, Leon Battista Alberti confirmed these notions in 1436 in his treatise De Pictura, in which he evoked orthogonals meeting at a single point. The Italian painters were thus considered to be a step ahead of their Flemish counterparts.

The Basque Country's industrial waste heat could be reusable

Many traditional industrial processes generate heat that is normally released into the atmosphere but that could be reused. In production processes such as smelting, iron and steel, paper or cement, between 35 and 50 percent of the heat generated is lost. The efficient reuse of this industrial waste heat or its recovery for use in other processes displays a significant potential for increasing energy efficiency in industry. However, in order to design strategies for exploiting this potential, data on the quantity and flow characteristics of this industrial waste heat needs to be available. This information is not always easy to obtain and many companies do not even have a systematic record of the energy flows present in their production processes.
