Physicists want to create novel compounds that surpass diamonds in heat resistance and nearly rival them in hardness. In a paper in the journal Materials, they investigate how the addition of boron, while making a diamond film via plasma vapor deposition, changes properties of the diamond material.
Research and development around new applications and industries based on the advanced material graphene – hailed as the “miracle material of the 21st century” – is the focus of a new Graphene Research Hub being launched at the University of Adelaide today.
A coral reef-dwelling starfish that creates highly resistant lenses from chalk has given an international team of researchers a biostrategy that could lead to new ways for toughening brittle ceramics in applications including optical lenses, automotive turbochargers and biomaterial implants.
A research team led by faculty at Binghamton University, State University of New York has developed an entirely textile-based, bacteria-powered bio-battery that could one day be integrated into wearable electronics.
Physicists at the U.S. Department of Energy’s Ames Laboratory compared similar materials and returned to a long-established rule of electron movement in their quest to explain the phenomenon of extremely large magnetoresistance (XMR).
For decades, scientists have been trying to make a true molecular chain: a repeated set of tiny rings interlocked together. In a study in Science published online Nov. 30, University of Chicago researchers announced the first confirmed method to craft such a molecular chain.
If you have looked closely at a microwave’s warnings or have experienced an accidental explosion, you know that certain foods pose a risk due to an increase in their internal pressure, and potatoes and hard-boiled eggs are among the most common culprits. Researchers from Charles M. Salter Associates will present their research on the sound pressures generated by exploding eggs at the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans, Louisiana.
What is the difference between linear chains and rings composed of the same material? The molecular building blocks are identical, but from a mathematical point of view the two structures have distinct topologies, namely ring and linear chain. This difference is readily recognizable on a macroscopic scale, as for example a golden ring and a gold bar, but represents a tricky task on the microscopic scale. The physicists Lisa Weiss and Christos Likos of the University of Vienna and Arash Nikoubashman of the Johannes-Gutenberg University of Mainz investigated strategies to separate nano- and microparticles of distinct topology. Their results are published in the high-impact journal ACS Macro Letters.
University of Washington engineers have developed the first 3-D printed plastic objects that can connect to other devices via WiFi without using any electronics, including a laundry bottle that can detect when soap is running low and automatically order more.
Physicists at West Virginia University have discovered a way to control a newly discovered quantum particle, potentially leading to faster computers and other electronic devices.
The results described in this work show the electrical resistivity measurement method has the potential to be an accurate means for measuring the water absorption of very fine particles. Such advances in characterization methods for fine particles support the broader acceptance of recycled concrete.
An innovative conductive composite, ionically conductive mortar, is developed in this study.
Researchers from the University of Minnesota College of Science and Engineering have found yet another remarkable use for the wonder material graphene—tiny electronic “tweezers” that can grab individual biomolecules with incredible efficiency. This capability could lead to a revolutionary handheld disease diagnostic system that could be run on a smart phone.
Scientists at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have shown that copper-based superconductors, or cuprates – the first class of materials found to carry electricity with no loss at relatively high temperatures – contain fluctuating stripes of electron charge and spin that meander like rivulets over rough ground.
Earlier this year, amorphous diamond was synthesized for the first time using a technique involving high pressures, moderately high temperatures and a tiny amount of glassy carbon as starting material. A father-son team at Clemson University has now successfully calculated a number of basic physical properties for this new substance, including elastic constants and related quantities. The results are reported this week in Applied Physics Letters.
New developments may now propel nanoswimmers from science fiction to reality thanks to unexpected help from bacteria. An international research team has demonstrated a new technique for plating silica onto flagella, the helix-shaped tails found on many bacteria, to produce nanoscale swimming robots. As reported this week in APL Materials, the group’s biotemplated nanoswimmers spin their flagella thanks to rotating magnetic fields and can perform nearly as well as living bacteria.
Scientists unlock the key to efficiently make a new class of engineering polymers.
An entirely human-made architecture produces hydrogen fuel using light, shows promise for transmitting energy in numerous applications.
Novel defect control in graphene enables direct imaging of trapped electrons that follow Einstein’s rules.
Metal-organic frameworks with chains of iron centers adsorb and release carbon monoxide with very little energy input.
