Can alkaline earth metals be used in quantum computing

first_img Explore further Daley is a physicist in the Institute for Theoretical Physics at the University of Innsbruck and the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences in Austria. He, along with Martin Boyd and Jun Ye at the University of Colorado, and Peter Zoller at Innsbruck, are proposing a quantum computing scheme that would make use of overlaying optical lattices to store information as well as perform computations. Much of this work was performed when the authors were guests at the California Institute of Technology in Pasadena, and their ideas are shared in Physical Review Letters: “Quantum Computing with Alkaline-Earth-Metal Atoms.”Electrons play a vital role in quantum computing with atoms, and when atoms are controlled with light, the electrons are also controlled. “That’s what makes alkali atoms nice to deal with,” says Daley. “They only have one valence electron, which makes the system really simple.” He then points out that alkaline earth metals offer an advantage over alkali atoms: “There are two electrons weakly bound. Even though the system is a little more complicated, there are some very nice properties.”Daley explains that it is possible to excite an electron to higher energy states in which they remain for a relatively long time. “The idea is to create two different traps using two different colors of light, one for atoms where the electron is excited and the other for atoms where it is not. This is possible because the atoms react to light, and go where the light is. Basically, we can make an array of bright spots of laser light – an optical lattice – where there is an atom in every bright spot.”In order to store information, Daley says, the spin of the nucleus is adjusted, also with laser light. “Atoms are initially stored in the lattice for the state where the electron is not excited. They can then be transferred to the state with an excited electron and transported to different parts of the system by moving the two different traps relative to each other. This can be used to perform computations with information stored on atoms in different parts of the lattice.”The paper Daley and his peers wrote expresses theory rather than describing the results of an experiment. However, it is possible that a demonstration might be possible fairly soon. “While this paper is theoretical,” he insists, “we build on techniques demonstrated in the laboratory, making use of technology that is currently applied to make atomic clocks.”Some of the details still need to be worked out, but Daley feels that it should be possible to build something workable to demonstrate the principle in the relatively near future. “We’ve taken our ideas of what can be done and matched them up with real numbers from experiments. This could lead to the first few steps and then be refined to make larger quantum computations.”“Our paper is a type of road map to set a course for what could be possible,” Daley continues. “We believe that with our technology it is likely that the first demonstrations are feasible on a timescale of two to three years.”More Information: Andrew Daley, Martin Boyd, Jun Ye and Peter Zoller. “Quantum Computing with Alkaline-Earth-Metal Atoms,” Physical Review Letters (2008).

Transparent Carbon Nanotube Films Likely Successor to ITO for Commercial Applications

first_img( — Will the legacy of Nobel prize winner Richard Smalley finally be fulfilled? Ever since his pioneering work in the mid 1990’s on the synthesis of carbon nanotubes, companies have been struggling to find a commercial application for this amazing material. There was a nanotech “bubble” of start-up companies, none of which managed to successfully IPO due to lack of realizable commercial revenue. Is that about to change? Recent research by Rice University and Unidym indicate that a fully realizable application is finally here for carbon nanotubes. Fortunately, it’s in one of the fastest growing display markets, touch screens. Citation: Transparent Carbon Nanotube Films Likely Successor to ITO for Commercial Applications (2009, April 10) retrieved 18 August 2019 from Carbon nanotubes (CNTs) are tiny hollow cylinders of carbon with tremendous electrical and optical properties. It turns out that very thin CNT films as thin as 10 or 20 nanometers are transparent to visible light and can conduct enough electricity to make them useful for many applications where these properties are needed. These applications include thin film solar cells, organic LEDs, and touch screens. Currently, a ceramic material called indium tin oxide (ITO) is used in these applications. This material is deposited in vacuum and is quite brittle. Carbon nanotubes, on the other hand, can be deposited from solution, and are remarkably robust and flexible. Films can be coated about 50 times faster than ITO films, and are almost unbreakable when flexed, tapped, strained, or smashed with a hammer, while ITO films are brittle and easy to crack under strain. Researchers predict that the first applications for these transparent CNT films will be as the electrodes in touch screens. This is because they already meet all technical requirements, and ITO has an issue in that it tends to crack after repeated use, thus degrading the touch screen response. Touch screens are a rapidly expanding market due to the popularity of the iPhone amongst other devices. By the end of the year, CNT films will begin to replace ITO in touch screens. As the technology continues to improve it will continue to take market share from ITO. This will be a remarkable achievement, and may issue in a new day for carbon nanotubes in various markets. I think Smalley would be pleased.More information can be found in: “Continuous and Scalable Fabrication of Transparent Conducting Carbon nanotube Films” by Dan, Irvin, and Pasquali in ACS Nano, published on the web April 08, 2009.© 2009 Will carbon nanotubes replace indium tin oxide?

Britain unveils desalination plant for London reservoirs

first_img More information: Explore further Citation: Britain unveils desalination plant for London reservoirs (2011, April 25) retrieved 18 August 2019 from Reverse osmosis water purification is a filtration process whereby brackish water is pressurized in a tank which pushes it through a thin membrane, allowing only the pure water to emerge out the other side. Because of the extra energy needed for pressurization, reverse osmosis generally costs up to twice as much as regular purification processes, which in turn causes taxpayers, especially in such a wet climate as Britain, to wonder about the wisdom of installing such a plant.But Thames Water, the company in charge of supplying drinking water to London, believes such a plant will be necessary in the future, citing the water restrictions put in place during the last extended drought in 2005/06, which was a catalyst for the construction of the plant. Critics have been quick to point out, however, that had the water company fixed its leaking pipes, some of the worst in the world, there would not have been a need for a new plant at all.Construction of the plant was finished in June of last year, but it wasn’t until just last month that the plant began actively pumping clean water into nearby reservoirs, albeit at only one sixth capacity. Simon Evans, spokesman for Thames Water, claims they are only doing so to test the system and train workers. The idea after all, is to fill the reservoirs if they fall low due to lack of rainfall, which coincidently or not, is exactly what Britain has been experiencing this spring.It’s likely the construction of the plant will cause other metropolitan areas to take notice as city planners the world over fall victim to criticism from thirsty city dwellers who suddenly find themselves at the mercy of varying weather patterns. Traditionally reverse osmosis plants have been built for areas with few other options, such as those in the Middle East; with this new plant in London, however, that could change. © 2010 ( — Britain has brought online a new desalination plant near London capable of providing the city with 150 million gallons (568 million litres) of water per day, should the need arise. At a cost of £270 ($445) million, and built over the past four years, the plant uses reverse osmosis to remove salt from the brackish water pumped in from the Thames Estuary, which it then pumps into local reservoirs, thus staving off the threat of drought.

Astronomers detect a doubly eclipsing quadruple star system

first_img More information: EPIC 219217635: A Doubly Eclipsing Quadruple System Containing an Evolved Binary, arXiv:1805.09693 [astro-ph.SR] have discovered a doubly eclipsing, bound, quadruple star system in the field of K2 Campaign 7. EPIC 219217635 is a stellar image with Kp=12.7 that contains an eclipsing binary (`EB’) with PA=3.59470 d and a second EB with PB=0.61825 d. We have obtained followup radial-velocity (`RV’) spectroscopy observations, adaptive optics imaging, as well as ground-based photometric observations. From our analysis of all the observations, we derive good estimates for a number of the system parameters. We conclude that (1) both binaries are bound in a quadruple star system; (2) a linear trend to the RV curve of binary A is found over a 2-year interval, corresponding to an acceleration, γ˙=0.0024±0.0007 cm s−2; (3) small irregular variations are seen in the eclipse-timing variations (`ETVs’) detected over the same interval; (4) the orbital separation of the quadruple system is probably in the range of 8-25 AU; and (5) the orbital planes of the two binaries must be inclined with respect to each other by at least 25∘. In addition, we find that binary B is evolved, and the cooler and currently less massive star has transferred much of its envelope to the currently more massive star. We have also demonstrated that the system is sufficiently bright that the eclipses can be followed using small ground-based telescopes, and that this system may be profitably studied over the next decade when the outer orbit of the quadruple is expected to manifest itself in the ETV and/or RV curves.

Two sub-Jovian exoplanets orbiting bright stars discovered Citation: Astronomers detect a doubly eclipsing quadruple star system (2018, June 4) retrieved 18 August 2019 from © 2018 The Kepler exoplanet-hunting telescope lost its two reaction wheels in 2013. Its mission was repurposed, and is now known as K2. The main goal of the revived spacecraft is to perform high-precision photometry of selected fields in the ecliptic. So far, the K2 mission has detected over 300 extrasolar worlds and many new stellar systems.EPIC 219217635 was initially identified by K2 as a potential quadruple star system during the spacecraft’s Campaign 7, which took place in late 2015. Afterward, a team of astronomers led by Tamas Borkovits of the Baja Astronomical Observatory of Szeged University, Hungary, has conducted follow-up observations of this star, which included radial-velocity spectroscopy, adaptive optics imaging, as well as ground-based photometric observations.”In this work we report the discovery with NASA’s Kepler space telescope during Campaign 7 of its two-wheeled mission (hereafter referred to as ‘K2’) of a quite likely physically bound quadruple system consisting of two eclipsing binaries,” the researchers wrote in the paper.The astronomers found that EPIC 219217635, located some 2,800 light years away from the Earth, is composed of two eclipsing binaries with orbital periods of about 3.6 and 0.62 days. The binaries are most likely in a 20 AU orbit around each other.EPIC 219217635 A consists of a star about 20 percent larger and more massive than the sun, and its smaller companion – with a radius of 0.74 solar radii and a mass of 0.68 solar masses. The larger component is about 2.24 more luminous than the sun and has an effective temperature of 6,473 K. The smaller star is less luminous and cooler, with a luminosity of 0.19 solar luminosities and an effective temperature of 4,421 K.The primary star of EPIC 219217635 B is approximately 30 percent larger and more massive than our sun. It has an effective temperature of 6,931 K and a luminosity of 3.66 solar luminosities. When it comes to the secondary star, it is similar in size to the sun (1.04 solar radii) and has a mass of only 0.41 solar masses. Its effective temperature is 4,163 K and its luminosity was calculated to be about 0.29 solar luminosities.Additionally, the researchers found that EPIC 219217635 B is evolved, and in this binary cooler and currently less massive star has transferred much of its envelope to the currently more massive star.In concluding remarks, the astronomers noted that EPIC 219217635 is a promising target for future observations even with small telescopes.”The system is sufficiently bright that the eclipses can be followed using small ground-based telescopes, and that this system may be profitably studied over the next decade when the outer orbit of the quadruple is expected to manifest itself in the eclipse-timing variation and/or radial velocity curves,” the paper reads. Using NASA’s Kepler spacecraft, an international group of astronomers has discovered a doubly eclipsing, bound quadruple star system. The newly found system, designated EPIC 219217635, consists of stars similar in size to our sun, with masses ranging from 0.41 to 1.3 solar masses. The finding was presented May 24 in a paper published on Explore further The disentangled and folded lightcurves of the 3.595-day ‘A’ binary and the 0.618-day ‘B’ binary (red dots).

Investigating the dynamics of nanoparticle formation from a precursor at atomic resolution

first_imgFor TEM observation, K2PtCl4 was first dissolved in deionized water in preparation to image its crystal structure. In the bright field TEM image, the crystallite was 50 nm x 60 nm in size. Gao et al. weakened the electron beam dose to the angstrom scale for less than 1 e/A2∙s to limit beam-induced sample reduction during the process of imaging. The scientists conducted high-resolution electron microscopy (HREM) at 300,000 x magnification to obtain 64 images from the same area. By averaging the images, the atomic columns were clearly resolved in the study. The high-resolution TEM image showed periodic lattice squares with an atom (yellow) surrounding those without bright atomic contrast (blue) in the center. Gao et al. compared the atomic resolution images with the existing atomic structure of K2PtCl4 to identify each individual element. The scientists identified the atoms in the corners as potassium (K), atoms in the middle of the edges of the squares as chlorine (Cl) and those in the center of the square in yellow as platinum (Pt). When Gao et al. increased the electron beam dose to 30 e/A2∙s, the lattice from K2PtCl4, which was originally viewed across the entire area developed into individual Pt clusters. In time, the nanoclusters grew more pronounced under the microscope. Low-dose atomic resolution imaging of K2PtCl4.

In a recent study, now published in Science Advances, interdisciplinary materials scientists Wenpei Gao and co-workers in the USA and China, studied the reaction kinetics of a solid-state platinum (Pt) precursor compound. In the study, they used an aberration-corrected transmission electron microscope (TEM) combined with low-dose electrons and in situ imaging. The scientists imaged the beam-sensitive Pt precursor; potassium tetrachloroplatinate (II) (K2PtCl4), at the atomic resolution to determine the individual atoms (K, Pt and Cl) involved in the synthesis of platinum nanoclusters. Gao et al. captured the material’s transformation to Pt nanoclusters in real time to show three-stage reaction kinetics, including (1) breaking of the ionic bond, (2) formation of PtCl2 and (3) reduction of the divalent Pt to Pt metal nanoclusters. In the new method, the scientists combined techniques to understand the transformation of chemicals at the atomic scale in real time without damaging the substrates and provided a new platform to study reaction kinetics. Gao et al. captured, identified and revealed the dynamics at different stages of decomposition, reduction and nucleation of the material. The work allowed them to understand the transformation kinetics of platinum from precursor to nanocluster as a promising avenue to study atomic-scale reaction dynamics.

Gao et al. revealed this process using FFT of the high resolution image under a low electron dose and high acquisition efficiency. On removal of the K species from the precursor, the lattice became unstable and compounds including PtCl2, KCl and Cl2 could move freely. When PtCl2 was reduced in to Pt, the molecules of Cl2 transitioned into the gas phase for removal from the TEM column. The zerovalent Pt species formed small nuclei or migrated and grew into large Pt nanoparticles.In this way, the scientists elegantly demonstrated the reduction kinetics in the study and illustrated the concept using atomic models. The observed findings of nucleation and reduction of Pt agreed with that of previously calculated free energy in the chemical reaction. This method can be applied to study additional material transformations in depth. The results will benefit the applications of nanostructures in nanophysics for new materials development, new energy processes in environmental remediation and in nanomedicine.

The scientists selected a sub-area of the sequential images and applied a fast Fourier transform (FFT) to discern the structure and the constituents. Gao et al. were able to obtain a time series of FFT patterns in the K2PtCl4 lattice, which also reflected the radial distribution function (RDF) (to find adjacent particles). The scientists then investigated the additional surface orientation of atoms in the material, aside from the Pt nanoclusters, to understand the location of K and Cl species. In the work, they used a series of imaging and analytical methods of materials science, starting with high-angle annular dark-field (HAADF) scanning transmission electron microscopy (STEM) and the 2-D energy-dispersive spectra (EDS) map to characterize the material. The results showed the signals from K and Cl in the background as evenly distributed across the area. When the scientists used electron energy loss spectroscopy (EELS) they further observed the existence of K and Cl from KCl, after the formation of Pt nanoparticles. Gao et al. gathered sufficient information from the reaction dynamics captured in real space via spectroscopy and characterization techniques in materials science. They proposed a microscopic process of reduction kinetics for K2PtCl4. Accordingly, the precursor K2PtCl4 first decomposed in to K+ and PtCl42- by breaking the weak ionic bond.

While nucleation is the initial step in materials synthesis, it is difficult to control nucleation kinetics without understanding how atoms interact. Platinum nanoparticles are usually synthesized in a liquid-phase reaction with C-H or Cl- as a precursor. During growth in such a system, the precursor is reduced by the reducing agent to form metal monomers with atomic arrangements based on metal-metal interactions. However, a microscopic mechanism that details the intermediate reaction steps is yet unavailable. As an alternative to materials synthesis in the liquid phase, nanostructures can also be grown in the solid phase. Studying the reduction process in the solid state can decipher materials transformation for fine control of materials synthesis. Understanding the kinetics of materials transformation from precursors to nanostructures at the atomic scale based on ionic bond breaking is therefore of considerable significance. The scientists opted to study the nucleation process in the solid phase without the liquid environment using characterization tools of X-ray nanodiffraction and TEM, which offered ultra-high resolution. The method resolved the evolving structures in real and reciprocal space, although the sensitivity of most chemical precursors to the electron beam due to photo illumination had previously made it nearly impossible to observe the initial atomic structure of the precursor. Explore further A key to materials synthesis is the ability to control the process of reduction kinetics and nucleation (phase transition) in materials. Understanding the reduction dynamics during the initial stage of material synthesis is limited due to the difficulty of investigating chemical reactions at the atomic scale. This is mainly because the chemical precursors used to synthesize materials can degrade when exposed to electron beams that are typically used to image compounds at atomic resolution.

Jupiters magnetic field could be moving Europas ocean

first_img © 2019 Science X Network Citation: Jupiter’s magnetic field could be moving Europa’s ocean (2019, March 12) retrieved 18 August 2019 from The Galileo spacecraft took this image of Europa, which is about the size of Earth’s moon, in 1996. Credit: NASA. Water plumes on Europa: Tasting an extraterrestrial ocean The researchers started by noting that Jupiter has a very strong magnetic field—strong enough to reach and impact its moons. They also noted that Europa’s underground ocean is salty. A magnetic field influencing a salty sea would result in the conduction of electricity, likely creating a jet stream in the ocean. To find out what sort of movement might occur and to uncover other possible impacts of the magnetic field on the moon’s ocean, the researchers created numerical simulations. The simulations showed a jet stream forming somewhere near the moon’s equator, moving as fast as a few centimeters per second and flowing opposite of the moon’s spin. Such an opposite flow, the researchers further noted, would result in stress on the moon’s surface, which could occasionally form cracks. This would explain the surface cracks observed on Europa by other researchers. They further note that not all of the energy from the magnetic field would be transferred to the ocean—some of it would dissipate off the moon, likely around the poles. And if that were the case, there would be evidence of the moon’s ice shell becoming thinner as melting water made its way to the surface. And again, that is just what has been observed—plumes of water spurting out from spots near the poles.The researchers suggest a jet stream on Europa could be compared to the Gulf Stream back here on Earth. Notably, our jet stream has been found to move compounds around in the ocean that are important for life. If Europa harbors life, its jet stream could be serving the same purpose.

Sale of meat goes up in Bengal thanks to govt infomercial

first_imgKolkata: The infomercial that was telecast on different channels following the direction of Chief Minister Mamata Banerjee to sensitise buyers about the right quality of meat, has ensured a rise in its sale.The sale of both raw and cooked meat in eateries in the state had witnessed a huge drop, after the carcass meat row came to light in mid-April. Now, being aware of the steps needed to be taken to buy the right quality meat, people are now once again purchasing the same, after assessing its quality properly.

According to an official of the state government, the telecast of the infomercial had been appearing for the past few weeks on television channels. “It (the infomercial) has become very effective as all aspects that people need to know to buy meat have been told in a nutshell and it was presented in a very simple way as well. It has helped people to pick up the information easily,” the official said.Though it would take some time to create awareness among the entire populace in the state, the Chief Minister’s initiative to telecast the infomercial on television channels has helped in regaining confidence of a large section of people.It may be recalled that the sale of chicken and meat preparations in eateries had dropped by around 40 percent, soon after the carcass meat row came to light. With constant monitoring by the local civic bodies in their respective areas, sale of stale meat has also been checked.When contacted, B P Gopalika, principal secretary, Animal Resources Development department, was not available for any comment.last_img read more
