All-fiber ellipsometer for nanoscale dielectric coatings
Measuring the refractive index and the thickness of thin films (films with a thickness from less than a nanometer to several microns) is essential to characterize them and improve the performance of sensors and devices that employ thin films. The mos.....»»
The technological challenge of non-stick pans: Teflon is still more effective than other coatings
A protocol designed by the University of Cordoba yields a simple and robust evaluation of the efficiency and durability of different commercial non-stick coatings used for food preparation.....»»
Ballistic transport in long molecular wires: Porphyrin nanoribbons
The conductance of classical electric components typically decays with increasing length. In general, this is also the same behavior found at the nanoscale with 1D molecular wires. Now, researchers have demonstrated that, once more, things are differ.....»»
Researchers demonstrate 3D nanoscale optical disk memory with petabit capacity
The most popular words of 2023 were recently released, with AI Large Language Model (LLM) unquestionably topping the list. As a front-runner, ChatGPT also emerged as one of the international buzzwords of the year. These disruptive innovations in AI o.....»»
CenturyLink left customers without Internet for 39 days—until Ars stepped in

Could fiber optic cable help scientists probe the deep layers of the moon?
An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth—but how would this technology fare on the moon, and what would it tell us about the deep layers of our nearest neighbor in space?.....»»
Research team develops a more durable coating against ice
Ice-repellent coatings have been around for some time, but until now they have been very sensitive and detach quite quickly from the surfaces they are meant to protect. A research team led by Anna Maria Coclite and Gabriel Hernández Rodríguez from.....»»
A New Startup Wants to Turn the Sugar You Eat Into Fiber
Americans eat too much sugar. Food tech company Zya is developing a substance to add to sweet foods that can convert some of that sugar into fiber in the digestive system......»»
Research team develops nanoscale device for brain chemistry analysis
Longstanding challenges in biomedical research such as monitoring brain chemistry and tracking the spread of drugs through the body require much smaller and more precise sensors. A new nanoscale sensor that can monitor areas 1,000 times smaller than.....»»
Study shows promise of transceiver-based sensing for active monitoring of fiber networks
Researchers have successfully used a coherent transceiver prototype to detect polarization changes that preceded a cable break in a live network. The work, which is one of the first demonstrations of field-based measurements for an active cable break.....»»
New process allows full recovery of starting materials from tough polymer composites
In a win for chemistry, inventors at the Department of Energy's Oak Ridge National Laboratory have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer, or CFRP, and later recovering all of its starting.....»»
Advanced measurements unravel nanoscale phenomena in tungsten diselenide
Semiconductor 2D materials are a few atoms thick, and some of them exhibit localized emission, where light is emitted from such a small part of the layer that only one photon at a time is produced. This localized emission has unique properties and is.....»»
Researchers reveal elusive bottleneck holding back global effort to convert carbon dioxide waste into usable products
Think of it as recycling on the nanoscale: a tantalizing electrochemical process that can harvest carbon before it becomes air pollution and restructure it into the components of everyday products......»»
Research team develops cold-hardiness kiwi fruit for immediate release to public
Kiwi fruits with their tangy green flesh are routinely purchased and devoured throughout the year by people across the nation. This is no surprise. Kiwi fruit is high in vitamin C, dietary fiber, and potassium. The subtropical fruit is also a favorit.....»»
A new way to visualize brain cancer at the nanoscale level
Researchers from Brigham and Women's Hospital and the Massachusetts Institute of Technology (MIT) have unveiled unprecedentedly detailed images of brain cancer tissue through the use of a new microscopy technology called decrowding expansion patholog.....»»
Fiber Optics Bring You Internet. Now They’re Also Listening to Trains
“Distributed acoustic sensing” looks for disturbances in fiber to detect earthquakes and even insects. Can it also improve rail safety?.....»»
A method to fabricate long rolls of subnanocomposite dielectric polymers
Engineers and material scientists have been trying to develop increasingly advanced devices, to meet the growing needs of the electronics industry. These devices include electrostatic capacitors, devices that can store electrical energy in a dielectr.....»»
Bessel-beam-based side-view measurement of seven-core fiber internal core distribution
Optical fiber, as the basic carrier of modern high-speed and high-capacity communication, is the key to the interconnection of the world. With the rapid development of the communications industry in recent decades, ordinary single-mode optical fiber.....»»
An efficient numerical program for studying light scattering at the nanoscale
When light encounters a particle, it interacts with the particle instead of just passing through smoothly. The light waves can get scattered in different directions because of the light-matter interactions......»»
Spray coating for grapes shows promise in battle between wildfire smoke and wine
Spray on coatings for grapes in the vineyard have promise in preventing off flavors in wines that result from contact with wildfire smoke, according to new Oregon State University research......»»
