Phys.org / Physicists investigate onset of effective mass
(Phys.org) —Although mass may seem to be a fairly straightforward concept, from a physics perspective it can be much more complex than weighing an object and reading off a number in grams. For instance, an object's mass can ...
Phys.org / Network paradox may help algorithms overcome 'universal limitation'
(Phys.org) —Sometimes paradoxes can be frustrating, but other times they can reveal something that was previously hidden. A new paradox in the field of network science, presented in a recent issue of EPL by Filippo Radicchi, ...
Phys.org / Quantum correlations make you never fail a test again
(Phys.org) —In the burgeoning field of quantum metrology, quantum effects are exploited to improve the precision when measuring a variety of parameters, such as phase, frequency, and magnetic fields. A main goal of this research ...
Phys.org / One-nm-thick graphene engine mimics two-stroke engine
(Phys.org) —It may sound impossible that a 1-nm-thick piece of graphene—made of just a single layer of carbon atoms and containing some chlorine and fluorine atoms—can function as a two-stroke combustion engine. After all, ...
Phys.org / Scientists overcome fundamental atom laser limit to build brightest atom laser to date
(Phys.org) —In an atom laser, millions of individual atoms propagate through space with minimal spreading, just like photons propagate in a coherent photon laser beam. Although both types of lasers are similar, atom lasers ...
Phys.org / Flexible all-carbon electronics integrated onto plants, insects, and more
(Phys.org) —Carbon-based electronics are being widely explored due to their attractive electrical and mechanical properties, but synthesizing them in large quantities at low cost is still a challenge.
Phys.org / Cascade solar concentrator greatly reduces solar cell footprint
(Phys.org) —Solar cells are often made of expensive materials, which is why much research is focused on finding cheaper materials in order to reduce the overall cost of solar energy. Another way around this problem is to ...
Phys.org / Micro-macro entangled 'cat states' could one day test quantum gravity
(Phys.org) —In Schrödinger's famous thought experiment, a cat's quantum state becomes entangled with the quantum state of a decaying nucleus, resulting in the odd situation that the cat is both alive and dead at the same ...
Phys.org / Solar cells made from polar nanocrystal inks show promising early performance
(Phys.org) —Achieving a balance between low-cost fabrication and high efficiency is key to the future success of solar cells. Over the past several years, researchers have been working on developing low-cost methods to manufacture ...
Phys.org / Mechanobiology: Enzyme micropump autonomously delivers insulin in response to glucose levels
(Phys.org) —For next-generation smart devices, autonomy is key. These devices will be able to power themselves, independently respond to stimuli, and perform different kinds of work, all without human intervention. With these ...
Phys.org / What does physics reveal about the sizes of sports fields?
(Phys.org) —From ping pong tables to golf courses, the sizes of sports fields vary widely. Although the sizes of sports fields were originally defined empirically—that is, by simply playing the sport rather than performing ...
Phys.org / Statistical physics algorithm helps basketball fans fill out NCAA bracket
(Phys.org) —Back in the early 2000s, Ed Feng was a Ph.D. student at Stanford studying chemical engineering. At the time, he never thought that his research on the dynamics of liquids using statistical physics would one day ...
Phys.org / What are the chances that a particle collider's strangelets will destroy the Earth?
(Phys.org) —At the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) in Long Island, New York, scientists study high-speed ion collisions that reveal what the universe may have looked like moments ...
Phys.org / Quantum engineering pushes refrigerator beyond classical efficiency limits
(Phys.org) —The laws of thermodynamics determine what is possible and impossible in classical systems. Lately, scientists have been working on establishing quantum analogues of these fundamental laws to determine the performance ...
Phys.org / Does the internet promote fairness of income distribution? (w/ Video)
(Phys.org) —The question of how an economic system should be structured in order to best promote fairness and equality is one of the most debated subjects of all time. By approaching the complexities of this question from ...
