Electrons are weird, but we’re starting to understand them a bit better.
You know how the old saying goes, that “diamonds are forever,” and giving your significant other a piece of diamond jewelry is considered to be a declaration of eternal love? Well, scientists working at the Borexino experiment in Italy may change the saying and send enamored young men scrambling for something that’s really eternal to profess their love — electrons.
A team of scientists from Switzerland, Russia, Denmark, Belgium and Canada has for the first time demonstrated that it is possible to track the movement of an electron inside a molecule in real time. Moreover, the scientists claim the electron movements can be manipulated allowing unprecedented control over chemical reactions and biological processes.
A team of Dutch and Belgian researchers demonstrated an electric circuit coupled with a magnetic insulator. The circuit uses so-called ‘spin waves’ instead of electrons to transmit information, something that was considered unpractical until not too long ago. The findings could help lead to a new class of electronics which are far more efficient since there’s less heat loss.
With the help of the most powerful laser in the world, scientists have achieved the highest energies yet in a compact particle accelerator. The tabletop-sized device accelerates electrons to high speeds by firing high power laser pulses in a controlled manner through a plasma tube only 9 centimeters in size. The accelerator ring at the Large Hadron Collider in CERN is
Many thousands of miles above our planet’s surface, electrons whiz through close to the speed of light. These electrons can streak past Earth in under five minutes, but can also become dangerous and have been known to destroy satellites and even injure astronauts in extreme cases. Most of the time, however, our gear and astronauts can rest safe since scientists have discovered
A team at University of Cambridge have harvested so-called ‘dark’ spin-triplet excitons with close to 100% efficiency, a breakthrough achievement which could vastly improve the efficiency of hybrid solar cells that use both organic and inorganic semiconductor junctions. An exciting solar future Excitons are basically electrons coupled to a hole (they’re attracted to each other and form a pair). An electron gets
Austrlian researchers have successfully developed transparent, ultra-thin, foldable solar cells.
The most basic principle of a solar cell is that it works by transferring the energy from an incoming photon (light) to a molecule, which causes one or more electrons to become displaced until an electrical current is formed. That’s the absolute gist of it, only besides electricity, some of the incoming photon energy gets lost as waste heat. Oddly
Typically in physics, your calculations and such are as precise as your use of constants. Meaning, if you have a skewed value for your constant, this will obviously affect all the computations where this constant is used. Today, all the important physical constants are rather precisely known, whether we’re talking about the speed of light or tau mass. For most
Photons are slippery fellas. Since they don’t have any electrons, they’re free to run through any matter, no matter how intense an electric field may be. Scientists at Stanford, however, have come by a monumental breakthrough after they devised a way to exert virtual force on photons using synthetic magnetism similar to the effect of magnets on electrons. The findings
Spintronics, or spin transport electronics, is a sort of emerging technology that scientists have been studying for a while in an attempt to leverage the encoding posibilities in an electron’s spin, in addition to its electrical charge. Recently, researchers at IBM Zurich have made a huge leap forward in turning spintronics into a viable technology for commercial solid-state memory devices
A Romanian scientist working at the University of Ohio captured the first-ever images of atoms moving within a molecule by applying a novel technique which basically turns the electrons of a molecule into flashbulbs; while this is currently only a new way to visualize molecules, researchers believe that one day it will be the key to controlling chemical reactions at
There are still many things we still don’t understand about the electron; only recently, a team from the Imperial College London concluded that the electron is actually incredibly round, thus making the most accurate estimate of its shape. The experiments, which spanned more than a decade, suggest that the electron differs from being round by less than 0.000000000000000000000000001 cm. Just
Paper is just paper, right ? Nothing fancy, nothing special, just plain old paper that we see and probably use every single day. Well, for Charles Kazilek at ASU, that statement couldn’t be further from the truth; incredible colours, from orange and purple to vibrant green, amazing textures, all of these were obtained from plain pieces of paper.
For physicists, antimatter is probably the most valuable substance ever; the slightest bit of it could provide extremely valuable information that can help clear out some of the most stressing issues in modern physics. However, the thing is these little gifts are pretty hard to wrap. However, the ALPHA project at CERN achieved this remarkable feat and took a huge
Since the Large Hadron Collider went back in business, all sort of rumors have been circling the scientific circles (and not only). However, until these rumors are proven wrong or right, the first official paper on proton collisions from the Large Hadron Collider has been published in this week’s edition of Springer’s European Physical Journal C. . Designed to reach
