Two worlds, one material
Until now, it has been clear: you can have a metal or a plastic, but not both in one. However, things don't have to stay that way. In the journal Angewandte Chemie, a Chinese research team has now reported a polymer with a metallic backbone that is conductive, thermally stable, and has interesting optoelectronic properties.

A quasiparticle that can transfer heat under electrical control
Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally.
Stuck in the Rough: How Aging Reactor Walls May Exhibit Lower Erosion
The plasma in a fusion device can erode device walls, releasing particles in a process called sputtering. These particles can reduce a device's performance and lifespan. In this study, researchers examined how the smoothness of device surfaces changes at small scales over time and how this affects erosion. This research will aid in the future design and operation of fusion power plants.
Time Projection Chamber Installed at sPHENIX
Experts assembling sPHENIX, a state-of-the-art particle detector at the U.S. Department of Energy's Brookhaven National Laboratory, successfully installed a major tracking component on Jan. 19. The Time Projection Chamber, or TPC, is one of the final pieces to move into place before sPHENIX begins tracking particle smash-ups at the Relativistic Heavy Ion Collider (RHIC) this spring.
Researchers reveal microscopic quantum correlations of ultracold molecules
Physicists are increasingly using ultracold molecules to study quantum states of matter.
New research computes first step toward predicting lifespan of electric space propulsion systems
Electric space propulsion systems use energized atoms to generate thrust. The high-speed beams of ions bump against the graphite surfaces of the thruster, eroding them a little more with each hit, and are the systems' primary lifetime-limiting factor.
Anna Lee Appointed AIP Foundation Executive Director
AIP is pleased to announce Anna Lee as the new executive director of AIP Foundation. Starting February 1, Lee will lead the foundation as it magnifies philanthropic support of the Institute. Her appointment as executive director will bring valuable leadership and strategic direction to the foundation as it continues to share the history of the physical sciences, motivate and encourage a new generation of scientists, attract and inspire new partners, and support AIP priorities through critical fundraising opportunities.
Researchers take a step toward novel quantum simulators
If scaled up successfully, the team's new system could help answer questions about certain kinds of superconductors and other unusual states of matter.
Lawrence Livermore's Popular Science on Saturday Lecture Series Moves to Las Positas College
Lawrence Livermore National Laboratory's (LLNL) popular lecture series, "Science on Saturday," returns Feb. 4 and runs through Feb. 25 at a new location: Las Positas College.
First Kilonova Progenitor System Identified
Astronomers using data from the SMARTS 1.5-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF's NOIRLab, have made the first confirmed detection of a star system that will one day form a kilonova -- the ultra-powerful, gold-producing explosion created by merging neutron stars. These systems are so phenomenally rare that only about 10 such systems are thought to exist in the entire Milky Way.
Desde Chile identifican una futura Kilonova
Utilizando datos del telescopio SMARTS de 1,5 metros ubicado en Cerro Tololo, un programa de NOIRLab de NSF y Observatorio AURA, un equipo de astronomos descubrio un sistema estelar que en el futuro formara una kilonova, es decir una explosion ultra poderosa, generadora de oro, que se produce por la fusion de estrellas de neutron. Este tipo de sistemas estelares son tan inusuales que se cree que existen apenas cerca de 10 en toda la Via Lactea.
Analog Mixed-Signal and Photonic Integrated Circuits expert presenting at ISSCC and OFC
Vishal Saxena is an associate professor in the University of Delaware's College of Engineering exploring Analog Mixed-Signal and Photonic Integrated Circuits (AMPIC).
New Non-Invasive Method to Assess Burns Shows High Accuracy
A team of Stony Brook University researchers believe they created a new method to significantly improve burn assessment. They are employing a physics-based neural network model that uses terahertz time-domain spectroscopy (THz-TDS) data for non-invasive burn assessment. Details of their method are published in a paper in Biomedical Optics Express.
Investigations reveal more evidence that Mimas is a stealth ocean world
When a Southwest Research Institute scientist discovered surprising evidence that Saturn's smallest, innermost moon could generate the right amount of heat to support a liquid internal ocean, colleagues began studying Mimas' surface to understand how its interior may have evolved.
Scientists Probe the Source of Stochastic Occurrence of Super-Knock in Engines Running on Hydrogen/Methane Fuels
Blends of hydrogen and methane are a promising alternative vehicle fuel that could help reduce carbon dioxide emissions. To make these fuels viable, researchers need to understand how they burn, especially in small, turbocharged internal combustion engines. In this study, researchers examined the impact of non-thermal chemical kinetics on "super-knock," a combustion mechanism that can cause severe engine damage.
Scientists release newly accurate map of all the matter in the universe
A group of scientists, including several with the U.S. Department of Energy's Fermi National Accelerator Laboratory, have released one of the most precise measurements ever made of how matter is distributed across the universe today.
Researchers complete first real-world study of Martian helicopter dust dynamics
Mars is a dusty planet. From tiny dust devils to vast storms that shroud the planet, dust is a constant challenge for research missions.
