Molybdenene—the "metallic" relative of graphene
Two-dimensional materials like graphene show fascinating properties such as superconductivity, extraordinary strength and exotic quantum phenomena. Scientists at Forschungszentrum Jülich, together with partners from the Indian Institute of Technolog.....»»
A path to graphene topological qubits
In the quantum realm, electrons can group together to behave in interesting ways. Magnetism is one of these behaviors that we see in our day-to-day life, as is the rarer phenomena of superconductivity. Intriguingly, these two behaviors are often anta.....»»
Gamified connecting rowing machine maker Ergatta raises $30M
As the world takes its first steps back to relative normalcy, there remains a major question mark around how profoundly our day-to-day is going to be changed for good. Nowhere does that question loom larger than fitness. Connected home machines have.....»»
Polymer-based coatings on metallic implants improve bone-implant integration
Traffic accidents, tumor resections, and congenital diseases can cause significant trauma, which can lead to large bone deformations and/or bone loss. Although bone has some capacity to regenerate, large bone defects cannot be healed without major me.....»»
Discovery of an elusive cell type in fish sensory organs
One of the evolutionary disadvantages for mammals, relative to other vertebrates like fish and chickens, is the inability to regenerate sensory hair cells. The inner hair cells in our ears are responsible for transforming sound vibrations and gravita.....»»
"Planar and curved" pyrrole-fused azacoronenes
Recent study on synthetic approaches toward polycyclic aromatic hydrocarbons (PAHs) such as graphene with a well-defined structure have attracted much attention. A research group at Ehime University has been studying the synthesis and fundamental pro.....»»
This miniature version of Starry Night was made with a “laser paintbrush”
New tool creates color on metal surfaces that can be changed, erased, rewritten Blurring the lines between science and art: researchers used a "laser paintbrush" to create art on metallic canvases. Researchers at ITMO University in Russia.....»»
Hungry fruit flies are extreme ultramarathon fliers, traveling up to six million times body length
In 2005, an ultramarathon runner ran continuously 560 kilometers (350 miles) in 80 hours, without sleeping or stopping. This distance was roughly 324,000 times the runner's body length. Yet this extreme feat pales in comparison to the relative distan.....»»
Tracking topological conditions in graphene
Scientists have been able to demonstrate that graphene nanostructures can be generated by annealing of a nanostructured silicon carbide crystal for a few years. "These two-dimensional, spatially strongly restricted carbon bands exhibit a vanishingly.....»»
Generation of super-resolved optical needle and multifocal array using graphene oxide metalenses
In a new publication from Opto-Electronic Advances, researchers led by Professor Baohua Jia at Swinburne University of Technology, Victoria, Australia, Professor Cheng-Wei Qiu at National University of Singapore, Singapore and Professor Tian Lan at B.....»»
Finally, 3D-printed graphene aerogels for water treatment
Graphene excels at removing contaminants from water, but it's not yet a commercially viable use of the wonder material......»»
Childbirth versus pelvic floor stability
Human childbirth is comparatively difficult because our babies' heads are large relative to our birth canals. This tight 'fetopelvic' fit increases the risk of obstructed labor, which in turn has potentially dire outcomes for both mother and child. I.....»»
The Thrusters Behind NASA"s Mission to the Asteroid Psyche
Hall thrusters have been used in satellites for years. Now, they'll play a crucial role in reaching a metallic asteroid called Psyche......»»
A graphene system that freezes electrons as the temperature rises
Two teams of researchers have independently found that there exists a certain type of graphene system where electrons freeze as the temperature rises. The first team, with members from Israel, the U.S. and Japan, found that placing one layer of graph.....»»
Research team demonstrates control mechanism for quantum material
How can large amounts of data be transferred or processed as quickly as possible? One key to this could be graphene. The ultra-thin material is only one atomic layer thick, and the electrons it contains have very special properties due to quantum eff.....»»
Entropy measurements reveal exotic effect in "magic-angle" graphene
Most materials go from being solids to liquids when they are heated. One rare counter-example is helium-3, which can solidify upon heating. This counterintuitive and exotic effect, known as the Pomeranchuk effect, may now have found its electronic an.....»»
Seismic coda used to locate and define damage from explosions
Comparison of coda waves, the scattered waves that arrive after the direct waves of a seismic event, can be used to determine the relative locations of two underground explosions, according to a new study published in the open-access journal The Seis.....»»
Graphene "smart surfaces" now tunable for visible spectrum
Researchers at The University of Manchester's National Graphene Institute have created optical devices with a unique range of tunability, covering the entire electromagnetic spectrum, including visible light......»»
Oxygen-promoted synthesis of armchair graphene nanoribbons on Cu(111)
On-surface synthesis has received great attention as a method to create atomically-precise one-dimensional (1D) and two-dimensional (2D) polymers with intriguing properties. In particular, graphene nanoribbons (GNRs), a category of quasi-1D nanomater.....»»
Researchers develop third and final "made-to-order" nanotube synthesis technique
The current method of manufacturing carbon nanotubes—in essence rolled up sheets of graphene—is unable to allow complete control over their diameter, length and type. This problem has recently been solved for two of the three different types of n.....»»
New insights into the formation of bulk metallic glasses
With the ability to produce metallic glass in bulk quantities, the distinct mechanical behavior of these materials has opened up new application opportunities. However, the poor room temperature plasticity of bulk metallic glasses (BMGs) impedes many.....»»
