Researchers have developed a unique way to create full-color holograms with the aid of surface plasmons.
Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster than similar devices (see video). This opens up completely new areas of application, such as in medicine.
(PhysOrg.com) -- A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos – nearly massless particles that travel at almost the speed of light. The message was sent through 240 meters of stone and said simply, "Neutrino."
Blisteringly fast Internet speeds, more robust connections and a big increase in network capacity at little extra cost, even in rural areas? It
(PhysOrg.com) -- IBM scientists today will report on a prototype optical chipset, dubbed “Holey Optochip”, that is the first parallel optical transceiver to transfer one trillion bits – one terabit – of information per second, the equivalent of downloading 500 high definition movies. The report will be presented at the Optical Fiber Communication Conference taking place in Los Angeles.
We know since the dawn of modern physics that although events in our everyday life can be described by classical physics, the interaction of light and matter is down deep governed by the laws of quantum mechanics. Despite this century-old wisdom, accessing truly quantum mechanical situations remains nontrivial, fascinating and noteworthy even in the laboratory. Recently, interest in this area has been boosted beyond academic curiosity because of the potential for more efficient and novel forms of information processing.
Scientists have created a new way to overcome many of the issues associated with bringing high-speed digital communications across challenging terrain and into remote areas, commonly referred to as the "last mile" problem. The researchers developed a record-speed wireless data bridge that transmits digital information much faster than today
New laser light source has a global market in consumer electronics. Mobile phones currently on the market are capable of showing high quality images and video, but the phones
Researchers have discovered the means by which a polymer known as PVDF enables capacitors to store and release large amounts of energy quickly. Their findings could lead to much more powerful and efficient electric cars.
Many of the communication tools of today rely on the function of light or, more specifically, on applying information to a light wave. Up until now, studies on electronic and optical devices with materials that are the foundations of modern electronics -- such as radio, TV, and computers -- have generally relied on nonlinear optical effects, producing devices whose bandwidth has been limited to the gigahertz (GHz) frequency region. (Hertz stands for cycles per second of a periodic phenomenon, in this case 1billion cycles).
(PhysOrg.com) -- Thanks to the flexible yet robust properties of carbon nanotubes, researchers have previously fabricated transistors that can be rolled, folded, and stretched. Now a team from Japan has made an all-carbon-nanotube transistor that can be crumpled like a piece of paper without degradation of its electrical properties. The new transistor is the most bendable reported to date that doesn’t experience a loss in performance.
(PhysOrg.com) -- Oxford University spinoff company, Oxford Nonopore has announced at this year’s Advances in Genome Biology and Technology conference in Florida, two new machines for sequencing genes. Of particular note is the MinION, a machine small enough to fit in the hand which can be plugged into a laptop’s USB port. The other, the GridION, is a larger version that can be stacked to increase processing power. Both rely on a technology known as strand sequencing whereby a nanopore (engineered protein) is used to pull strands of DNA through a hole where a microchip measures minute changes in the electrical current in the membrane around it as individual bases, or pairs are pulled through. Because of the way it is done, much longer sections of DNA can be examined at once, doing away with the need to examine small sections independently and then knitting the results together with a computer afterwards.
(PhysOrg.com) -- The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers at the University of Pennsylvania are pushing circuitry forward in a different way, by replacing electricity with light.
Traditionally, a super-yacht is a vast, luxurious vessel where its opulence is only matched by its fuel consumption. However recently, the super wealthy have been making an attempt to show their green credentials by purchasing greener and more efficient ships. Sauter Carbon Offset Design (SCOD) have not set the standard by which all other green super-yachts will now be measured with the 42m Ocean Supremacy - the largest, greenest super-yacht in the world.
