In the Journal of Vacuum Science & Technology A, researchers deploy an array of microscopic coils to create a magnetic field and stimulate individual neurons. The magnetic field can induce an electric field in any nearby neurons, the same effect created by an electrode but much more precise.
In Applied Physics Letters, researchers use laser treatments to transform ordinary cork into a powerful tool for treating oil spills. They tested variations of a fast-pulsing laser treatment, closely examining the nanoscopic structural changes and measuring the ratio of oxygen and carbon in the material, changes in the angles with which water and oil contact the surface, and the material’s light wave absorption, reflection, and emission across the spectrum to determine its durability after multiple cycles of warming and cooling.
AIP is delighted to announce the appointment of Alejandro de la Puente as director of the Society of Physics Students and AIP’s first Student Engagement Officer.
While asleep, the area of birds’ brains dedicated to singing remains active, triggering vocal muscles without producing sound. In Chaos from AIP Publishing, researchers translate the muscle activity to synthesize the songs of avian dreams. Reproducing distinctive bird calls provides a window into the contents of the bird’s dreams.
With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. In Physics of Fluids, an AIP Publishing journal, researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding.
Polymer-based hydrogels are used to treat skin ailments and in tissue engineering because of their ability to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture and not very resilient to external forces like rubbing against clothing, sheets, or wound dressings.
By evaluating sound vibrations produced by the airflow induced within the lungs and bronchial tree during normal breathing as well as those produced by the larynx during vocalizations, doctors can identify potential disease-related abnormalities within the respiratory system.
For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. In the Journal of Vacuum Science & Technology Aresearchers in China turned to atomic layer deposition and developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. The team used alternating layers of aluminum-doped titanium carbide and silicon nitride and together the materials prevent nearly all light from reflecting off the coated surface. The coating absorbs 99.3% of light while being durable enough to survive in harsh conditions.
Despite the technological advances keeping meat fresh for as long as possible, certain aging processes are unavoidable. Adenosine triphosphate is a molecule produced by breathing and responsible for providing energy to cells. When an animal stops breathing, ATP synthesis also stops, and the existing molecules decompose into acid, diminishing first flavor and then safety. Hypoxanthine and xanthine are intermediate steps in this transition. Assessing their prevalence in meat indicates its freshness. In AIP Advances, researchers developed a biosensor using graphene electrodes modified by zinc oxide nanoparticles to measure HXA. The team demonstrated the sensor’s efficacy on pork meat.
In JVSTB, researchers report successful results from a hand-held breast cancer screening device that can detect breast cancer biomarkers from a tiny sample of saliva.
AIP is delighted to announce the appointment of Trevor Owens as its first Chief Research Officer.
China’s Chang’e-5, the first lunar sample return mission since the Soviet Union’s Luna 24 in 1976, delivered 1.73 kilograms of regolith from the Oceanus Procellarum, a plane named for its vast size.
AIP and APS are pleased to announce David Brydges as the recipient of the 2024 Dannie Heineman Prize for Mathematical Physics “for achievements in the fields of constructive quantum field theory and rigorous statistical mechanics, especially the introduction of new techniques including random walk representation in spin systems, the lace expansion, and mathematically rigorous implementations of the renormalization group.”
Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors publishing in the American Journal of Physics analyzed the pressure chamber’s Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.
AIP Publishing is excited to announce the appointment of Julia R. Greer as the new editor-in-chief of Journal of Applied Physics. Greer is the Mettler Chair Professor of Materials Science, Mechanics, and Medical Engineering at the California Institute of Technology and the Fletcher Jones Foundation Director of Caltech’s Kavli Nanoscience Institute. As editor-in-chief, Greer’s vision for Journal of Applied Physics is to build upon its long and distinguished history and establish an even broader reach.
The Heineman Foundation, AIP, and American AAS are pleased to announce John E. Carlstrom as the winner of the 2024 Dannie Heineman Prize for Astrophysics.
Shuttlecocks, also known as birdies or birds, are traditionally made from duck feathers, but nylon shuttlecocks have become more widely used because of their superior durability. Their flight behavior, however, is far different from that of traditional feather birdies. In Physics of Fluids, scientists in India explored the aerodynamic performance of nylon shuttlecocks at various flight speeds. Through computational analyses based on two-way fluid-structure interactions, the team coupled equations governing air flow with equations determining skirt deformation of a shuttlecock in flight.
In Physics of Fluids, researchers from the University of Utah report snowflake accelerations in atmospheric turbulence.
Researchers from Shanghai Jiao Tong University have developed a promising new solar-powered atmospheric water harvesting technology that could help provide enough drinking water for people to survive in difficult, dryland areas: They synthesized a super hygroscopic gel capable of absorbing and retaining an unparalleled amount of water. .
In Physics of Fluids, scientists demonstrate how bloodstains can yield valuable details by examining the protrusions that deviate from the boundaries of otherwise elliptical bloodstains. The researchers studied how these “tails” are formed using a series of high-speed experiments with human blood droplets less than a millimeter wide impacting horizontal surfaces at various angles. They found that the tail length can reflect information about the size, impact speed, and impact angle of the blood drop that formed the stain.
