In a paper in the scientific journal Laser and Particle Beams today, lead author Heinrich Hora from the University of New South Wales in Sydney and international colleagues argue that the path to hydrogen-boron fusion is now viable, and may be closer to realization than other approaches, such as the deuterium-tritium fusion approach being pursued by US National Ignition Facility and the International Thermonuclear Experimental Reactor under construction in France.
A team of scientists from Krasnoyarsk Scientific Center (Siberian Department of Russian Academy of Sciences) and Siberian Federal University synthesized thin crystal ferromagnetic films and developed a technology for their shaping. Processed films can be used in electronic and spintronic chips. The results of the study were published in Thin Solid Films journal.
Where do the molecules required for life originate? It may be that small organic molecules first appeared on earth and were later combined into larger molecules, such as proteins and carbohydrates. But a second possibility is that they originated in space, possibly within our solar system. A study, published in this week's The Journal of Chemical Physics, shows that a number of small organic molecules can form in a cold, spacelike environment full of radiation.
Researchers at the University of Pittsburgh, Pennsylvania have created glass that lets through a large amount of light while appearing hazy, a combination of properties that could help boost the performance of solar cells and LEDs.
Physicists from Konstanz, Princeton and Maryland created a stable quantum gate as a basic element for the quantum computer.
You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a UC Berkeley team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.
Excitonium has a team of researchers at the University of Illinois at Urbana-Champaign... well... excited! Professor of Physics Peter Abbamonte and graduate students Anshul Kogar and Mindy Rak, with input from colleagues at Illinois, University of California, Berkeley, and University of Amsterdam, have proven the existence of this enigmatic new form of matter, which has perplexed scientists since it was first theorized almost 50 years ago.
The way in which electronic devices operate relies on the interaction between various materials. For this reason, researchers need to know exactly how specific chemical elements inside a computer chip or a transistor diode behave, and what happens when these elements bond. Physicists of University Jena, Germany, have now developed an innovative method that enables them to obtain several different types of information simultaneously from the interior of a nanoscale building block, and this while it is in the active state.
An international research team reveals the subtle properties of mirror molecules. The researchers examined camphor photoionization using an ultrafast laser. Circularly polarized light directed at camphor molecules allowed the measurement of electron emission, giving the first precise measurement of the asymmetry in the reaction of a camphor molecule. It confirms that more electrons are emitted in one direction, but also leads to the discovery that they are emitted seven attoseconds earlier than in the opposite.
While magnetic monopoles in the form of elementary particles remain elusive, there have been some recent successes in engineering objects that behave effectively like magnetic monopoles. Now, scientists at IST Austria have shown that there is a much simpler way to observe them: they have demonstrated that superfluid helium droplets can act as magnetic monopoles. Such droplets have been studied for decades, but until now, this fascinating characteristic had gone entirely unnoticed.
