Graphene is one of the most recently-discovered materials in the scientific community, at the tender age of 5 years old. In spite of only being discovered in 2004, it is already considered to be one of the possible replacements for silicon, the chemical that at this point provides the basis for the world of electroni... |

Whilst conducting a new series of experiments involving the analysis of protons, scientists at the US Department of Energy's (DOE) Thomas Jefferson National Accelerator Facility (Jefferson Lab) discovered that the companions protons had inside the atomic nuclei changed the positive particles' internal stru... |

In their quest for ever-smaller and ever-faster computer chips and transistors, scientists have, over the past few years, dedicated enormous amounts of time, energy, and money to producing electronics at the smallest scale possible. This has gone all well and good for some years, but now this field of research is app... |

The beautiful depth that crystals have is one of the things that have fascinated people since the early days of civilization. Fortune tellers use it to scout the future, while some believe that the stones channel mystical powers, which can be harnessed for various purposes. But scientists have no ambition of learning... |

A team of physicists from the University of Michigan (UM) announce the creation of the world's first atomic-scale map of the promising quantum dots, semiconductors whose excitons are confined in all three spatial dimensions. Quantum dots potentially have the ability to influence a large number of production proc... |

One of the deepest mysteries related to modern physics is the phenomenon of high-temperature superconductivity, in which regular chemicals become superconductors at specific temperatures and pressures. In an attempt to further the scientific understanding of these processes, the US Department of Defense (DOD) awarded... |

Atomic physicists were recently puzzled to discover a type of gas that could have the ability to start a new type of physics all by itself. The chemical exhibits some very peculiar properties, when its initial conditions are changed. For instance, when its temperature is dropped to the ultra-cold range, it begins to ... |

Weighing any and all types of atoms individually has been a long-standing goal in science, and now efforts done by experts from the University of Melbourne, in Australia, have brought these attempts one nano-step closer to success. In their studies of gold nanoparticles of highly uniform shapes and sizes, the investi... |

A lot of people have thankfully heard of carbon nanotubes in recent years, and most of them know that they are incredibly small constructs, built at the nanoscale, and which are made of single layers of carbon atoms, stuck together in the shape of tubes. But not many people know that these tubes, also known as buckyt... |

In a research published in the June 25th issue of the scientific journal Nature, experts from the University of Michigan report the development of a new laser technology that allows for a greater magnetic field stability in quantum dots (QD), which are one of the candidates for the main components of quantum bits (QB... |

As every doctor who ever operated inside a patient without actually seeing what they were doing can tell you, having a device that shows precisely what is happening in a non-intrusive manner could be the decisive advantage in saving a patient's life. For a long time, physicists have postulated that it could be p... |

Drawing inspiration from the classic spinning electric motor, theoretical physicists have proposed the construction of a full quantum-mechanic version of it, entirely made up of two atoms spinning incredibly fast in a ring of light. The weird thing about it is that researchers say it could be built at today's kn... |

Experts at the University of Texas in Austin have recently announced the creation of the world's thinnest stretch of superconducting material. Made entirely out of lead, the sheet measures only two atoms in thickness, a true achievement, given the physical and chemical properties of the metal. In charge of the r... |

Researchers at the University of California in Los Angeles (UCLA) have just recently created the smallest incandescent light bulb in history, which is about 100,000 times narrower and 10,000 times shorter than the one first designed by Thomas Edison. The filament of the new bulb is only 1.4-micrometer long and approx... |

There is a growing consensus at the international level that quantum computers are the future of complex calculations, but the goal of having such devices that actually work remains distant, on account of the fact that the very basic principles on which quantum technology is based are very unstable. This means that a... |

In 2008, the US Defense Advanced Research Projects Agency (DARPA) has commissioned three multi-university scientific teams to investigate the possibility of developing a technology that would allow for trapping various types of atoms into micro-scale “light crystals,” also designated as optical lattices. ... |

Using an atomic force microscope to detect all the subtle changes that occur within a material when it's pulled apart or compressed is a very good method of scientific observation. Unfortunately, it's also one of the most expensive, so researchers at the University of Illinois have only recently devised a n... |

An international team of scientists has recently discovered a hidden magnetic "quantum order" that manifests itself over long chains of almost 100 atoms in a material that normally displays a magnetic disorder.This finding could help the development of new materials and devices for super quantum computers, that make... |

Thousands of atoms form pairs and start shaking theirs booties on a mid-air dance floor, in fact a lattice of light formed by six laser beams. Their ability to move with the beat is not only a beautiful experiment, but it could be a breakthrough that could bring the quantum computers closer to reality.The quantum co... |

A team of scientists successfully performed what can be called "molecular surgery." What they did was snip off a single hydrogen atom from a molecule and then added it back on again. This is the first time a single chemical bond between two atoms has been broken and reforged.Moreover, the scientists claim to be able ... |

There is a place on Earth, deep underground, where whole atoms of antimatter are being built. This is no top secret government installation, it's just the largest physical experiment in the world. CERN's Large Hadron Collider, built below ground level, spanning in at the border of two countries, Switzerlan... |

This was what a team of Australian and Chinese scientists were trying to find: simple equations describing complex behaviors of atomic systems. This has been the central aim of physics for some time now, and this team says they've got observational evidence of a universal behavior.Peter Drummond and Xia-Ji Liu,... |

A team of scientists in the US developed a new device that can trap large numbers of atoms in a 3-D array, and can then image each one individually. This new method could be very useful in the development of the quantum computer, due to the fact that it can address each atom individually.The basic principle of quant... |

The fastest enterprise hard disks spin at 15,000 RPM, and can achieve sequential media transfer speeds of up to and beyond 110 MB/s.Modern hard drives use the spinning motion of a disk to move magnetic regions past a component that can read and change the data encoded on these regions. They record data by magnetizing... |
