Textile maker Delta teams up with startup Sonovia to pilot innovative fabrics

Delta Galil Industries, Ltd., a textile manufacturer of branded and private label apparel, is setting up a strategic partnership with Israeli startup Sonovia, a maker of textiles with sustainable and antimicrobial properties, to pilot the use of new fabrics for its product lines. Under the agreement, Sonovia and its machinery manufacturing partner, Brückner Textile Machinery, will install an ultrasonic fabric-finishing applicator at Delta Galil’s innovation center in Karmiel, Israel, to pilot the application of new, eco-responsible fabric finishes offering antimicrobial and anti-odor protection and other traits to products Delta manufactures for its global customers. Delta Galil Industries, founded in 1,975 is a maker of men and women’s underwear, bras, socks, baby clothing, leisurewear and nightwear. The brands it supplies its products for include Schiesser, Eminence, Athena and PJ Salvage. To date, Sonovia has developed two applications for its technology: an anti-bacterial, anti-odor and anti-viral application, and a spray to make textiles water-repellent.

The Ramat Gan, Israel-based startup, founded in2013by Shay Herchcovici and Joshua Herchcovici, uses a patented nanotechnology process developed at Israel’s Bar-Ilan University to embed particles, compounds, and molecules of desired properties directly into textiles, creating a fabric that retains its properties through multiple washings.

The company’s partnership with Delta Galil “constitutes a significant landmark” in Sonovia’s path to commercialize its technology and strengthens Delta Galil’s position as a specialist in high-performance, sustainable manufacturing innovation, the statement said.

“This strategic agreement with Delta Galil constitutes a vote of confidence in Sonovia’s eco-friendly, performance fabric-finishing technology from one of the world’s leading manufacturers of activewear and apparel,” said Sonovia’s chairman and CEO Joshua Herchcovici.

The Smallest Engine in the World Is Literally an Ion

Circa 2019

An international team of physicists have created what they’re calling the world’s smallest engine. How small is it? The entire engine is a single calcium ion, making it around 10 billion times smaller than a car engine.

The experimental engine was conceived by an international team led by Professor Ferdinand Schmidt-Kaler and Ulrich Poschinger of Johannes Gutenberg University in Mainz, Germany. The engine is electrically charged, which makes it easy to trap using electric fields. The moving parts of the engine are the ion’s “intrinsic spin.” On an atomic level, spin is a measurement of an atom’s angular momentum.

Within the engine, spin is used to capture and convert heat absorbed from laser beams into oscillations, or vibrations, of the trapped ion. The vibrations act as a flywheel and its energy is placed into units called “quanta,” predicted by quantum mechanics.

New Electronic Material: Engineers Create Double Layer of Borophene for First Time

New material maintains borophene ’s electronic properties, offers new advantages.

For the first time, Northwestern University engineers have created a double layer of atomically flat borophene, a feat that defies the natural tendency of boron to form non-planar clusters beyond the single-atomic-layer limit.

Although known for its promising electronic properties, borophene — a single-atom.

Scientists discover quantum mechanical switching in ferritin structures similar to those found in neural tissue

Quantum mechanics generally refers to the wave-like properties of things that are commonly considered to be particles, such as electrons. This article discusses evidence of a quantum mechanical switching function that is performed by strictly biological structures—ferritin protein layers that are found in cells including neural tissue.

Many scientists are investigating quantum biology, which is the application of quantum mechanics to investigate biological functions. It has recently been used to answer a number of previously unanswered questions, such as the mechanisms behind photosynthesis and the way birds can perceive magnetic fields. These quantum biological effects generally involve electrons hopping or tunneling over distances of several nanometers, behavior that is incompatible with particles but which makes sense with waves.

Ferritin is a spherical iron storage protein that is found in plants and animals. Early studies of ferritin to look for quantum mechanical effects were conducted at cryogenic temperatures, because it was thought that biological structures were too “warm and wet” to exhibit such effects. Those studies were somewhat inconclusive. But when ferritin was subsequently electrically tested at room temperature, it was discovered that electron tunneling was occurring.

Metallic Nanostructures for Generating Exotic Forms of Light

LSU Quantum researchers rearrange photon distribution to create different light sources.

For decades, scholars have believed that the quantum statistical properties of bosons are preserved in plasmonic systems, and therefore will not create different form of light.

This rapidly growing field of research focuses on quantum properties of light and its interaction with matter at the nanoscale level. Stimulated by experimental work in the possibility of preserving nonclassical correlations in light-matter interactions mediated by scattering of photons and plasmons, it has been assumed that similar dynamics underlie the conservation of the quantum fluctuations that define the nature of light sources. The possibility of using nanoscale system to create exotic forms of light could pave the way for next-generation quantum devices. It could also constitute a novel platform for exploring novel quantum phenomena.

Ultrafast electron microscope opens up new avenues for the development of sensors and quantum devices.

Everyone who has ever been to the Grand Canyon can relate to having strong feelings from being close to one of nature’s edges. Similarly, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have discovered that nanoparticles of gold act unusually when close to the edge of a one-atom.

Experimental Confirmation of the Fundamental Principle of Wave-Particle Duality

Complementarity relation of wave-particle duality is analyzed quantitatively with entangled photons as path detectors.

The twenty-first century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early twentieth 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.

To test the fundamental principle of wave-particle duality and complementarity quantitatively, a quantum composite system that can be controlled by experimental parameters is needed. So far, there have been several theoretical proposals after Neils Bohr introduced the concept of “complementarity” in 1,928 but only a few ideas have been tested experimentally, with them detecting interference patterns with low visibility. Thus, the concept of complementarity and wave-particle duality still remains elusive and has not been fully confirmed experimentally yet.
