Tying molecules in knots Explore further Called a pentafoil, the five point knot is the most complex kind of molecule synthesized from other building blocks, other than those found in DNA, and having a means for building them could lead to all sorts of new materials that could be both strong and flexible.To build the molecule, the team started with a negatively charged chloride ion, to serve as a pulling force, or anchor. They then added other parts, such as iron ions with a positive charge, and chains of carbon atoms. They then chemically “programmed” the whole works to assemble itself into the pentafoil, with five chains looped over and under one another and connected to form one single knotted strand, with a single chloride ion sitting squarely in the center holding the whole knot together. The finished product is made up of just 160 atoms and very much resembles a traditional two-dimensional five pointed star.As an interesting side note, the researchers found that if they removed the single chloride ion after the knot was completed, they were left with a molecule that was hungry for that missing ion, which could mean they’ve found a new type of chlorine sensor.In devising a means to create a pentafoil, the researchers have created not just a new type of man-made molecule, but a blueprint for creating other types of knotted molecules which could lead to all sorts of new and exotic materials.

This is where atoms are bonded together to form strands, which are then twisted around one another in a way that looks very much like a length of rope tied into an everyday knot. Such molecules when used to make whole structures can provide both strength and elasticity. Unfortunately, forcing atoms to bind together in ways that result in knotted molecules has proven to be an especially difficult task; so much so, that until now, no one has been able to make a molecule that has more than three points. Now, researchers at the University of Edinburgh, have figured out a way to create one with five points, as they describe in their paper published in Nature Chemistry, essentially creating what looks like a flat five point star.center_img More information: A synthetic molecular pentafoil knot, Nature Chemistry 4, 15–20 (2012) doi:10.1038/nchem.1193AbstractKnots are being discovered with increasing frequency in both biological and synthetic macromolecules and have been fundamental topological targets for chemical synthesis for the past two decades. Here, we report on the synthesis of the most complex non-DNA molecular knot prepared to date: the self-assembly of five bis-aldehyde and five bis-amine building blocks about five metal cations and one chloride anion to form a 160-atom-loop molecular pentafoil knot (five crossing points). The structure and topology of the knot is established by NMR spectroscopy, mass spectrometry and X-ray crystallography, revealing a symmetrical closed-loop double helicate with the chloride anion held at the centre of the pentafoil knot by ten CH···Cl– hydrogen bonds. The one-pot self-assembly reaction features an exceptional number of different design elements—some well precedented and others less well known within the context of directing the formation of (supra)molecular species. We anticipate that the strategies and tactics used here can be applied to the rational synthesis of other higher-order interlocked molecular architectures. © 2011 PhysOrg.com Journal information: Nature Chemistry X-ray crystal structure of molecular pentafoil knot [6]Cl(PF6)9.

Image credit: NASA/JPL-Caltech Citation: New ideas add further mystery to why there is less lithium-7 in the universe than expected (2012, July 20) retrieved 18 August 2019 from https://phys.org/news/2012-07-ideas-mystery-lithium-universe.html © 2012 Phys.org (Phys.org) — Thirty years ago, cosmologists Monique and François Spite of the Paris Observatory, turned the world of astrophysics upside down when they noticed that there appeared to be a distinct lack of lithium-7 in old stars in the halo of the Milky Way, which led to questions about why there wasn’t more as expected by theories about the Big Bang. Since then, more research has shown that lithium-7 simply refuses to conform to models and theories about how the universe began; there’s just not enough of it. Now, things have grown worse as researchers Fabio Iocco and Miguel Pato from Stockholm University and Technische Universität in Munich, have published a study in Physical Review Letters describing what they believe is lithium-7 production by certain black holes. Astrophysicist team suggests axions could explain dearth of lithium-7 in dark matter theorycenter_img Journal information: Physical Review Letters Current theory holds that some fourteen billion years ago, the Big Bang occurred and everything we know came about as a result. In those first few moments afterwards, elements were formed and persist to this day. Modeling of the Big Bang has found that all of the elements in existence conform to theories suggesting how much of each should exist. Except for lithium-7. For some reason, there is approximately just a third of what there should be and astrophysicists don’t know why. Now, new research suggests that there should be even more, maybe twice what was originally thought.Iocco and Pato, in looking at x-ray sources that come from binary star arrangements that are thought to harbor black holes, have found what appears to be torus shaped matter (from one of the stars) swirling around and towards the gravity source. In doing the math, they calculate that the matter nears the speed at which light travels as it approaches, reaching temperatures of 100 billion K. Under those conditions, the duo suspect that helium nuclei colliding could result in the creation of lithium-7, which if true would mean that there is even more of the stuff missing than researchers had first thought. They write that if something on the order of 1% of such systems are producing helium-7, the amount of it produced would equal as much as is believed to have been created after the Big Bang.Astrophysicists have suggested a lot of theories to explain the dearth of helium-7, but thus far, none have panned out, and none of them are proposing that the original ideas used to describe how much there should be, are wrong.

DOI:10.1103/PhysRevLett.109.021102 (Arxiv pre-print: http://arxiv.org/abs/1206.0736 )AbstractWe study the synthesis of lithium isotopes in the hot tori formed around stellar mass black holes by accretion of the companion star. We find that sizable amounts of both stable isotopes 6Li and 7Li can be produced, the exact figures varying with the characteristics of the torus and reaching as much as 10-2M⊙ for each isotope. This mass output is enough to contaminate the entire Galaxy at a level comparable with the original, pregalactic amount of lithium and to overcome other sources such as cosmic-ray spallation or stellar nucleosynthesis.last_img read more

Qcloud project to allow online users a taste of quantum computing

first_img Quantum computing with recycled particles Officials with Bristol University in the U.K. have announced at this year’s British Science Festival, that they intend to put their two-quantum bit (qubit) processor online for use by some people on the Internet. Called the Qcloud project, the idea is to get scientists, those in academics and even the general public used to the idea of quantum computing so as to be prepared when real quantum computers arrive. © 2013 Phys.org Explore further Citation: Qcloud project to allow online users a taste of quantum computing (2013, September 13) retrieved 18 August 2019 from https://phys.org/news/2013-09-qcloud-online-users-quantum.htmlcenter_img More information: www.bristol.ac.uk/physics/rese … ntum/qcloud/project/ This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Quantum computers are based on quantum processors that use qubits instead of electricity to represent data. The processor at Bristol computes results by first firing two photons from a blue laser—special optics cause them to become entangled. Programming is done via phase shifters which alter the speed of the photons. The idea is that quantum computers—because a qubit can exist in multiple states at once, allowing it to generate multiple solutions to a problem simultaneously—should be able, eventually, to far outstrip the abilities of current machines. Most computer scientists believe it’s only a matter of time before truly useful quantum computers are built and put into service—estimates range from a couple of years to a couple of decades.The Qcloud quantum “computer” is housed at the Centre for Quantum Photonics on the University’s campus. Because it uses just two qubits, the machine isn’t capable of doing much, but that isn’t the point. Instead, it’s to get people ready for the time when such computers become a reality. Bristol officials note that currently there are just a handful of people who have any idea of how to program a real quantum computer.To prevent a glut of programs that don’t work from accessing the real computer, Bristol will first require prospective programmers to create a program on a web based simulator. If users are optimistic about their results, they can then submit them for review. If the program they’ve written is deemed worthy, it will be run on the real quantum processer. The university has already made the simulator available online—the processor will be made accessible via the Internet next week, September 20.By providing access to a real quantum computer, officials at Bristol are hoping to excite the next generation of programmers who will be creating new types of code that hasn’t even been envisioned yet.last_img read more

Quantum thermal transistor can control heat currents

The content is provided for information purposes only. World’s first successful use of an electric circuit to compensate for distortions in electric signals due to heat The researchers, Karl Joulain et al., at the University of Poitiers and CNRS in France, have published a paper on the quantum thermal transistor in a recent issue of Physical Review Letters.”To manage electricity, one uses electronic diodes, transistor and amplifiers,” Joulain told Phys.org. “We would like to do the same thing with thermal currents. We would like to make logical thermal circuits in the same way electronic thermal circuits have been designed. In this way, wasted heat could be guided, switched on or off, amplified or modulated.”Although this is not the first thermal transistor, it is the first that is made of quantum objects. Other thermal transistors are made with macroscopic materials, such as solids or phase change materials. The new quantum thermal transistor consists of three two-level systems, meaning they have two states. These systems can be implemented as spins, where each spin can be in either the up state or the down state. Any one of these spin systems can control the heat current flowing through the other two. The researchers theoretically demonstrated that the thermal current can be controlled, modulated, and amplified by a sufficiently large amount so that it can switch the spins between their two states, producing a transistor effect. The transistor could be used to control thermal currents in a variety of nanostructures made of quantum objects. In the future, for instance, the device could in principle be fabricated with quantum dots embedded in nanoparticles.”My future research plans are to optimize the device and of course to find collaborations to make the experiment at the quantum level,” Joulain said. The quantum thermal transistor consists of three two-level systems, which can be implemented as spins with an up and a down state. Any one of these systems can control the heat current that flows to the other two, resulting in switching their spins. Credit: Joulain et al. ©2016 American Physical Society (Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in applications that recycle waste heat that has been harvested from power stations and other energy systems. Currently, there are methods for transporting and guiding this heat, but not for controlling, amplifying, and switching the heat on and off, as the quantum thermal transistor can do.

Physicists propose first method to control single quanta of energy

first_imgIn the proposed experiment, two energy reservoirs (S and D) made of trapped ions transport energy quanta to each other by coupling to the spins in a quantum magnet placed between them. Credit: Alejandro Bermudez and Tobias Schaetz, New Journal of Physics. CC-BY-3.0 (Phys.org)—Physicists have proposed what they believe to be the first method to control the transport of energy at the level of single energy quanta (which are mostly phonons). They show that it’s theoretically possible to control the flow of single energy quanta through a quantum magnet using lasers with carefully controlled frequencies and intensities. Explore further Journal information: New Journal of Physics More information: Alejandro Bermudez and Tobias Schaetz. “Quantum transport of energy in controlled synthetic quantum magnets.” New Journal of Physics. DOI: 10.1088/1367-2630/18/8/083006 Citation: Physicists propose first method to control single quanta of energy (2016, August 29) retrieved 18 August 2019 from https://phys.org/news/2016-08-physicists-method-quanta-energy.html If implemented, the method could allow researchers to explore quantum energy transport phenomena that are expected to be completely different than what is observed in macroscopic energy transport. In general, understanding energy transport in small-scale devices could lead to the development of methods for reducing the energy dissipation in shrinking computer hardware (however, the researchers note that computer hardware differs from the particular setup proposed here).The scientists, Alejandro Bermudez, at the Institute of Fundamental Physics in Madrid, Spain, and Tobias Schaetz, at the Albert Ludwigs University of Freiburg and the Freiburg Institute for Advanced Studies, both in Freiburg, Germany, have published a paper on their proposed method in a recent issue of the New Journal of Physics. “We have identified a new quantum mechanism that would allow to control the transport of energy/heat at the level of single energy quanta,” Bermudez told Phys.org. “This mechanism can be considered as an analogue of Coulomb blockade in electronic nanodevices, and we have proposed to test it using experiments with crystals of self-assembled trapped atomic ions.”In the study, the scientists propose building an energy reservoir using trapped magnesium ions. By using a laser to heat and cool the ions, the ions can be made to absorb or release tiny amounts of energy, acting as tiny energy reservoirs. Then to transport the energy, the researchers propose placing a synthetic quantum magnet—which consists of a long line of magnetic spins that form a chain—between two energy reservoirs. When the reservoirs are coupled to the spins in the magnet, they can exchange energy with each other in the form of single phonons. In this way, quantum-scale energy transport occurs across the spin chain. The scientists explain that energy transport at the quantum level can be thought of as analogous to charge (electron) transport at the quantum level, which has already been well-documented. Just as single-electron transport is very different than bulk electron transport, quantum energy transport is expected to be very different than energy transport on a large scale. © 2016 Phys.org Long-distance transport of electron spins for spin-based logic devices One particular phenomenon associated with single-electron transport, which is not observed at larger scales, is called the Coulomb-blockade effect. In nanoscale electronic devices, electrons must gain a certain level of charging energy in order to tunnel across a barrier. When one electron manages to gain this energy and tunnel, it blocks the simultaneous tunneling of other electrons because additional electrons would require additional energy. The resulting blockade effect violates Ohm’s law of charge transport, and results in only one electron tunneling at a time.In the new study, the physicists theoretically demonstrated that an analogous Coulomb-blockade effect occurs with nanoscale heat transport, which again does not appear at larger scales. The scientists derived a quantum master equation for the transport of energy that shows that there is a “transport window” that defines the energy level needed for energy quanta to travel through a quantum magnet. Similar to the situation with electrons, energy transport is blockaded when the energy quanta do not have sufficient energy. This effect, which the researchers call the Ising blockade effect, violates Fourier’s law of heat conduction and results in the transport of only one energy quantum at a time.If the proposed experiment can be realized, the researchers expect to observe the Ising blockade effect along with many other interesting quantum effects in energy transport that so far have been restricted to electronic currents. At this stage, it’s difficult to tell what applications quantum energy transport may have.”If the same effect can be shown to be more general, and applicable to other physical setups, it may yield unexpected applications similar to single-electron electronics in Coulomb-blockaded devices,” Bermudez said.One of the biggest challenges to realizing the experiment will be to design a device that can directly measure such tiny amounts of heat energy.”We are considering exploring this type of physics in the laboratory of my coauthor, Professor Schätz, at the University of Freiburg,” Bermudez said. “Although the experimental requirements to implement the proposed scheme are stringent, Professor Schätz leads a world-class team of fantastic researchers with the required technology to face this challenge.” This document is subject to copyright.

Astronomers detect a strong outburst of an embedded young stellar object

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. UKIDSS-J185318.36+012454.5 is located in the vicinity of the IRAS 18507+0121 source and probably belongs to the massive star-forming region associated with GAL 034.4+00.23 HII region. The object is at least 5,000 light years away from the Earth and its neighborhood contains massive protostars with an age of about 100,000 years, as well as a low-mass stellar population approximately 1 million years old. The stellar object was classified as an intermediate mass YSO less than 100,000 years old.Recently, a team of researchers led by Elena Nikoghosyan has combed through the data and images provided by the United Kingdom Infrared Telescope (UKIRT) in Hawaii to search for evidence of outbursts in star-forming regions. They used the archival infrared and submillimeter data from UKIRT Galactic Plane Survey (UKIDSS GPS) and found that an outburst occurred in UKIDSS-J185318.36+012454.5 in the period of 2004-2006.”UKIRT Galactic Plane Survey is a deep survey with good space resolution. Therefore, it provides very useful information for researchers who study star forming regions. In particular, for detection of UKIDSS-J185318.36+012454.5 outburst, UKIRT Galactic Plane Survey was the basic source of information,” Nikoghosyan told Phys.org.According to the paper, the amplitude of brightness of the detected outburst is at least five mag. The object remained at this level of brightness until 2014.The results of the research allowed the scientists to re-classify UKIDSS-J185318.36+012454.5 as an eruptive variable with mixed characteristics, namely a MNor-type object, and Nikoghosyan emphasized the significance of the study.”Eruptions of pre-main sequence stellar objects are rare events, thus a new outburst is always noteworthy. And I think that the discovery of a new eruptive variable UKIDSS-J185318.36+012454.5 with a so strong outburst (delta K > 5 mag) was a big success,” she said.The authors of the paper also sought the most plausible explanation for eruptive variability of young stars. They noted that several physical mechanisms, such as rotation, cool or hot spots, accretion-driven wind and outflow can explain the near-infrared variability, but these mechanisms often produce short-term variability with amplitude that is not expected to exceed one mag in the K band.”In our opinion, all of the proposed explanations of this phenomena to date (eruptive variability of young stars) do not explain it completely, most likely due to lack of information. With respect to this object, we can only assume that this outburst corresponds to the transition between two evolution stages: Class 0 (no optical and near-infrared emission) and Class I (generally optically obscured). But this is only an assumption,” Nikoghosyan concluded.The researchers now plan further observations of UKIDSS-J185318.36+012454.5. However, these studies could only be conducted in collaboration with scientists from other countries due to the fact that in Armenia, there is no opportunity to observe this object in the infrared range.

We report the discovery of a strong outburst of the embedded young stellar object (YSO), namely UKIDSS-J185318.36+012454.5, located in the star-forming region associated with IRAS 18507+0121 source and GAL 034.4+00.23 HII region. Methods. Using the archival photometric data and images we determined the amplitude and the epoch of the outburst, as well as the evolution stage and the basic parameters of the object. Results. According to the near and mid-infrared colors and spectral energy distribution, we classify the object as an intermediate-mass young stellar object (YSO) with Class 0/I evolution stage. The outburst occurred in the period of 2004-2006. The amplitude of brightness is as least Ks = 5.0 mag. The summation of the photometric and spectral data does not allow to classify UKIDSS-J185318.36+012454.5 as FUor or EXor. We can consider it as an eruptive variable with mixed characteristics or MNor type object. (Phys.org)—Astronomers from the Byurakan Astrophysical Observatory in Armenia have discovered a strong outburst of the embedded young stellar object (YSO) designated UKIDSS-J185318.36+012454.5. This newly detected event could provide important insights for the understanding of eruptive variability of young stars.

A team of researchers with members from Singapore, Indonesia, Ireland and the U.K. has found more evidence of a tsunami approximately 600 years ago that destroyed communities in the same part of Sumatra as the 2004 tsunami. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of gravestones and pottery in the area and what they found.center_img © 2019 Science X Network The Indian Ocean tsunami of 2004 was devastating, killing over 280,000 people and displacing millions. The tsunami was caused by an earthquake just off the coast of Sumatra, one of the islands that make up Indonesia. One of the hardest-hit areas was the province of Aceh—fatalities there were approximately 160,000. In this new effort, the researchers have found more evidence of a similar tsunami striking the same region in 1394.Geologic evidence uncovered after the 2004 tsunami showed that there had been another tsunami 600 years earlier, but there was little evidence indicating how powerful or devastating it had been. The work by the new team began when one of its members came across several Muslim gravestones that had been uncovered by the 2004 tsunami. The researchers began searching in earnest for other evidence of people living in the area before and after the earlier tsunami.The researchers report that they found evidence of 10 settlements in the area, nine of which had been completely destroyed by the 1394 tsunami. The 10th settlement was on a hilltop beyond the reach of the giant waves. Study of ceramics from the period showed the destroyed communities dated back to the 11th and 12th centuries. Study of the surviving settlement showed that the ceramics in the area from that time period came from as far away as Syria and China. It, too, suffered from the tsunami, however, as it went into decline after the tsunami. The researchers also found evidence that showed Muslim traders moving in to establish new communities where the old ones had stood. The researchers believe these people eventually established an Islamic kingdom known as the Aceh Sultanate. They further suggest that studies like theirs could provide more information regarding what happens to regions that are destroyed by tsunamis.

Cocaine worth Rs 50 cr recovered at IGI Airport

first_imgIn what is believed to be the largest cocaine recovery so far in India, two South African women and a Ghana national have been apprehended, with around 9.6 Kgs of cocaine recovered from their possession, at the Indira Gandhi International Airport in Delhi on Tuesday morning. The value of the cocaine consignment was estimated to be around Rs 50 crore in the international market The accused women took an Emirates flight from Brazil and arrived at India after a short halt in Dubai. They were reported to be caught red-handed by sleuths of Narcotics Control Bureau (NCB) at terminal 3 of the IGI airport around 9.20 am on Tuesday, said an NCB official. He further informed that the accused women had hidden the drugs in cavities inside their baggage. The Ghana national, who has been living in Delhi for around the past two years, had allegedly come to receive the consignment.“Investigation of the case is underway and we are expecting to recover more from them, who are suspected to be members of an international drugs syndicate,” the NCB official added.NCB sources believe this to be the highest cocaine recovery by any agency so far, in India. In 2012, NCB had recovered 7 kg cocaine in Delhi, which was reported to the highest recovery till Tuesday.last_img read more

SC seeks details of cases lodged in trafficking of girls

first_imgThe Supreme Court on Tuesday asked all states and Union Territories (UTs) to furnish details to the Centre of cases registered by them for the offence of trafficking of girls for sexual exploitation during 2014 to September 30, 2015.Expressing concern over trafficking of girls, a three judge bench headed by Justice A R Dave asked the Union Cabinet Secretary to set up a high-powered inter-ministerial committee to deal with the issue.The bench, also comprising Justices Madan B Lokur and Kurian Joseph, sought a report by November 15 on the progress made in setting up of the Organised Crimes Investigating Agency (OCIA) for investigating the cases of human trafficking as such offences involve many states.It asked all states and UTs to provide the data of FIRs, registered between 2014 to September 30, 2015 with regard to girl child trafficking under certain provisions of the IPC and the Immoral Traffic (Prevention) Act, to the Ministry of Home Affairs (MHA) within a fortnight. The MHA will collate the data and will file an affidavit before November 18, the next date of hearing, the court said.During the hearing, the court hailed the steps taken by the Centre and National Legal Services Authority (NALSA) on issues like prevention, rescue and rehabilitation of the victims of trafficking for commercial and sexual exploitation.The counsel for the Centre on Tuesday referred to the recent Central Advisory Committee meeting in which states and UTs were invited and they discussed the report of NALSA.NALSA had suggested roles of various stakeholders in the prevention, rescue and rehabilitation of victims of trafficking for commercial and sexual exploitation and had sought a direction to the Centre that the OCIA be set up to investigate the cases of human trafficking and organised crime.last_img read more
