Tracking particles containing charm quarks offers insight into how quarks combine

Nuclear physicists are trying to understand how particles called quarks and gluons combine to form hadrons, composite particles made of two or three quarks. To study this process, called hadronization, a team of nuclear physicists used the STAR detector at the Relativistic Heavy Ion Collider—a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE's Brookhaven National Laboratory—to measure the relative abundance of certain two- and three-quark hadrons created in energetic collisions of gold nuclei. The collisions momentarily "melt" the boundaries between the individual protons and neutrons that make up the gold nuclei so scientists can study how their inner building blocks, the quarks and gluons, recombine.

Twisting magnetic fields for extreme plasma compression

A new spin on the magnetic compression of plasmas could improve materials science, nuclear fusion research, X-ray generation and laboratory astrophysics, research led by the University of Michigan suggests.

Rsearchers suggest modification of quantum encryption system with compact detector

A new system can significantly lower the production costs costs of mass quantum key distribution (QKD) networks, which will make them available to a wider user audience. This will make it possible to use QDK in the regular fiber-optic cable infrastructure. The paper was published in Scientific Reports.

Shaking light with sound

Piezoelectric materials can convert electrical voltage to mechanical displacement and vice versa. They are ubiquitous in modern wireless communication networks such as in cellphones. Today, piezoelectric devices, including filters, transducers and oscillators, are used in billions of devices for wireless communications, global positioning, navigations, and space applications.

The smallest micro-gripper, grown on optical fibers, is operated remotely with light

Researchers at the Faculty of Physics, University of Warsaw, used the liquid crystal elastomer technology to demonstrate a series of micro-tools grown on optical fibers. The 200-micrometer gripers are controlled remotely, without electric wiring or pneumatic tubing, with green light delivered through the fibers—absorbed light energy is directly converted into the gripper jaws' action.

Transparent inorganic multicolour displays enabled by zinc-based electrochromic devices

Multicolour electrochromic displays are one of the most versatile applications because they can retain their colored states without the need to supply electrical power. However, the simultaneous colouration of the counter layer when operating a conventional electrochromic display restricts the color overlay effects. Additionally, the operation of conventional electrochromic displays requires external voltages to trigger the colouration/bleaching processes, which makes the conventional electrochromic displays far from a net-zero energy consumption technology.

New nuclear magnetic resonance method enables monitoring of chemical reactions in metal containers

Nuclear magnetic resonance (NMR) is employed in a wide range of applications. In chemistry, nuclear magnetic resonance spectroscopy is in standard use for the purposes of analysis, while in the medical field, magnetic resonance imaging (MRI) is used to see structures and metabolism in the body. Scientists at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), working in collaboration with visiting researchers from Novosibirsk in Russia, have developed a new method of observing chemical reactions.

New organic material unlocks faster electronic devices

Mobile phones and other electronic devices made from an organic material that is thin, bendable and more powerful are now a step closer thanks to new research led by scientists at The Australian University (ANU).

Sensor for non-spoofable biometric identification easily integrated in smart phones

Holst Center has demonstrated the world's first organic near-infrared large-area image sensor capable of detecting the unique pattern of veins in a person's hand via reflected light. The sensor opens the door to highly secure, non-spoofable biometric identification for security-critical applications such as passports and payment authentication, and can be easily integrated into devices such as smartphones.

Chasing particles with tiny electric charges

All known elementary particles have electric charges that are integer multiples of a third of the electron charge. But some theories predict the existence of "millicharged" elementary particles that would have a charge much smaller that the electron charge and could account for the elusive dark matter that fills the universe. An international team of researchers has now reported the first search at the Large Hadron Collider (LHC)—and more generally at any hadron collider—for elementary particles with charges smaller than a tenth of the electron charge.

'Celestial sleuth' sheds new light on Vermeer's masterpiece 'View of Delft'

Johannes Vermeer is one of the most celebrated artists of the 17th century's Dutch Golden Age period. Widely known today for his "Girl with a Pearl Earring," he was famed for his mastery in rendering the effects of light and shadow. Nowhere is this technical precision more evident than in his masterpiece, "View of Delft", a vibrant cityscape that has captivated viewers for centuries. Because few details of Vermeer's life survive to the present day, little is known about when "View of Delft" was painted. Art historians have long assumed Vermeer painted it sometime during late spring or early summer of 1660. Based on the lighting, scholars have offered a wide variety of times of day: morning, mid-day, afternoon and sunset have all been mentioned. Now, a team of researchers led by Texas State University astronomer, physics professor emeritus and Texas State University System Regents' Professor Donald Olson has applied his distinctive brand of celestial sleuthing to Vermeer's masterpiece, using the artist's signature gift for depicting light and shadow to resolve the long-standing uncertainty over when it was painted.

Researchers give robots intelligent sensing abilities to carry out complex tasks

Picking up a can of soft drink may be a simple task for humans, but this is a complex task for robots—it has to locate the object, deduce its shape, determine the right amount of strength to use, and grasp the object without letting it slip. Most of today's robots operate solely based on visual processing, which limits their capabilities. In order to perform more complex tasks, robots have to be equipped with an exceptional sense of touch and the ability to process sensory information quickly and intelligently.

Improved test methods for safer battery systems
