Telescoping nanotubes offer new option for nonvolatile memory

first_img Brewer Science, Nantero to commercialize carbon nanotube solution for nonvolatile memory As Kang and Jiang emphasize, getting the core nanotube to stay in contact with an electrode, even after removal of the electrical field, is vital for performance. This “bistability” requires balancing all the forces that act upon the sliding core nanotube, in an effort to obtain the correct collision time at a high speed. With platinum electrodes, the scientists’ simulation achieved switching times of around 10-11 seconds, and data erasing times of around 10-12 seconds—very competitive with top designs.“The demonstrated bi-stability, stable at two different telescoped positions, of this nanotube unit makes it feasible for the unit to behave as a switch, i.e., switching from one stable position to the other, and thus to serve as a non-volatile memory,” Jiang explained. Kang and Jiang’s research shows optimism for telescoping nanotubes, although the application is still in its early stages. For example, the scientists performed their simulations at the very low temperature of 1K, meaning further research must investigate the dynamics at room temperature.Overall, predictions vary widely in the field of next-generation nonvolatile memory technologies, especially regarding how long it will take for a fully mature and commercially viable type to accommodate a wide range of devices, and—in a more competitive spirit—exactly which technology(ies) that will be.“The prospects for the perceived revolutionary advancements have led to active research and development programs in many major corporations, such as Hewlett-Packard, IBM, Lucent, Motorola, Siemens, and Hitachi, etc.,” said Jiang. “It is likely that a functioning prototype of a molecular processor will be demonstrated in the next two to three years, but commercialization will face many challenges, such as the lack of infrastructure for mass production.”For more information on telescoping nanotubes, see Jiang’s Webpage: www.engr.ucr.edu/~qjiang/ .

All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. Although nonvolatile memories are common today—from cell phone cards to CDs to hard drives and flash disks—scientists envision a nonvolatile memory whose high speed and power would take the place of Random Access Memory (RAM). RAM’s high-speed currently makes it responsible for displaying applications and data while the computer is on, but it is a volatile memory, meaning all data is lost when the power is turned off. A next-generation nonvolatile memory would combine the speed of RAM and nonvolatility—enabling computers to boot up as fast as you can turn on the TV, as well as eliminating the need for secondary storage devices (such as external hard drives).“Research and development on molecular-scale memory and electronics, including data storage and computing devices, are extremely vibrant in the worldwide research communities,” scientist Qing Jiang told PhysOrg.com. “One of the widely perceived advantages is revolutionary advancements in density and speed, compared to the current silicon technology.”During the past few years, scientists have investigated the telescoping motion of nanotubes for nano applications, opening up the possibility for data storage. Now, Jiang and Jeong Won Kang have designed a device that could provide both nonvolatile RAM and terabit solid-state storage based on these telescoping nanotubes. The scientists also analyzed their design’s dynamic characteristics using molecular dynamics simulations to narrow down the best possible design.In the set-up, the movable core nanotube can slide inside a stationary nanotube by varying the electrostatic forces. This “telescope” lies between two electrodes, which are neutral when at rest. But by negatively charging one of the electrodes and positively charging the core nanotube, the nanotube can overcome the van der Waals force keeping the inner and outer nanotubes together, and move toward the oppositely charged electrode. Alternatively, by positively charging the other electrode and negatively charging the core nanotube, the nanotube would slide the other way. High damping would send the core nanotube back in the center.The contact between the core nanotube and an electrode creates a conduction pathway, and can be determined by measuring the resistance in this area, which marks a junction. With three possible positions (right electrode contact, left electrode contact, and no contact), the device could occupy three states, and therefore write one of three bits. In the midst of a widespread and potentially highly lucrative search for next-generation nonvolatile memory, scientists from the University of California have put to use an interesting characteristic of carbon nanotubes. When one hollow nanotube is inserted into a second (slightly larger) nanotube, scientists can achieve a rapid telescoping motion that can be applied to binary or triple digit memory for future molecular-scale computers.

The researchers, Qianyan Zhang, et al., from institutes in Beijing and Germany, have published their study on the tiny fullerene cage in a recent issue of Angewandte Chemie. While previous research has shown that fullerene cages can be used to surround molecules, here the chemists also designed a way to close (and re-open) the cage to let a water molecule in and out. One of the keys was making the cap the exact size to allow a single water molecule to pass through, and modifying the classic carbon-60 form of fullerene accordingly. Due to its chemical properties, the phosphate moiety used for the cap can be easily removed and re-attached to the edge of an orifice in the fullerene cage, and can sufficiently lock a single water molecule inside.The tiny container could have applications in transporting small molecules or radioactive atoms for medical purposes and other uses.

CRESST team finds new evidence of dark matter

first_img(PhysOrg.com) — In the never ending search for proof that dark matter really exists, new findings have emerged from a team working under a big mountain in Italy. The group, from the Max Planck Institute in Germany, have pre-published a paper on arXiv, and have also given a talk at the Topics in Astroparticle and Underground Physics conference in Munich where they describe how their CRESST II detector has recorded 67 events which they say cannot be explained by anything other than Weakly Interacting Massive Particles (WIMPS), a type of dark matter. Dark matter is of course, at least theoretically, the stuff that holds everything in the universe together. WIMPS are thought to be a kind of dark matter that doesn’t interact much with normal matter such as the stuff that we call the Earth and everything on it. Thus, such WIMPS wouldn’t have any trouble passing through the mountain above the detector, which is comprised of bunches of tungsten held very near absolute zero. The idea being that if a WIMP were to strike the tungsten, a tiny bit of light would be given off that could be observed and recorded. Of course regular old run of the mill cosmic rays can pass through mountains as well and collide with tungsten too. But those kinds of strikes are easily discernable and thus can be discounted; hence the excitement of team and their findings.The team using the CRESST II detector isn’t the only game in town, and the problem is, some of them aren’t able to obtain the same results. Other’s looking to discredit the whole notion of dark matter such as the CoGeNT project going on in Minnesota, wound up finding evidence of the opposite, as did the DAMA/LIBRA team, which has been running experiments for the past 12 years. Unfortunately, other teams such as XENON and CDMS II haven’t been able to find any evidence of dark matter at all.In addition to recording the strikes on their tungsten detector, the team also recorded the amount of energy released when such collisions occur, which can be used to calculate the mass of the particle that did the striking. In this case, the team found that they weighed somewhere between 10 and 20 gigaelectronvolts, which is lighter than researchers have expected. This new bit of evidence helps boost the idea that dark matter really does exist, though it doesn’t go far enough to prove it. As is the usual case, more science will have to be done before anything definitive can be declared.

Angloher et al., arXiv:1109.0702v1 [astro-ph.CO] arxiv.org/abs/1109.0702AbstractThe CRESST-II cryogenic Dark Matter search, aiming at detection of WIMPs via elastic scattering off nuclei in CaWO$_4$ crystals, completed 730 kg days of data taking in 2011. We present the data collected with eight detector modules, each with a two-channel readout; one for a phonon signal and the other for coincidently produced scintillation light. The former provides a precise measure of the energy deposited by an interaction, and the ratio of scintillation light to deposited energy can be used to discriminate different types of interacting particles and thus to distinguish possible signal events from the dominant backgrounds. Sixty-seven events are found in the acceptance region where a WIMP signal in the form of low energy nuclear recoils would be expected. We estimate background contributions to this observation from four sources: 1) “leakage” from the e/gamma-band 2) “leakage” from the alpha-particle band 3) neutrons and 4) Pb-206 recoils from Po-210 decay. Using a maximum likelihood analysis, we find, at a high statistical significance, that these sources alone are not sufficient to explain the data. The addition of a signal due to scattering of relatively light WIMPs could account for this discrepancy, and we determine the associated WIMP parameters.CRESST website: www.cresst.de/cresst.php One of the CRESST detector modules.

US Homeland Security reportedly set to deploy ultrasensitive spectrometer

first_img(Phys.org) — Online tech magazine, Gizmodo has stirred up a hornet’s nest of paranoid editorials across the globe by printing an article written by an unknown PhD student who claims that the US Homeland Security department is planning to deploy a new kind of scanning device that is so sensitive it will make all other security measures at airports moot; and worse will be able to do so at a distance allowing the process to occur without the knowledge of the person being scanned. 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. In the piece, the author, designated simply as NAC, says that the device has been developed by a private company called Genia Photonics, which is apparently chock full of physicists and engineers. It’s described as being able to pick up on the presence of mere molecules of suspicious substances (using apparently harmless, terahertz radiation) such as chemical weapons, gunpowder residue or even heightened levels of adrenaline in the bloodstream, all from a distance of up to 50 meters. What’s more it’s really fast, doing its work in picoseconds, and portable, meaning that DHS could set up the scanner at airports, train stations, border crossings or wherever else they believe a possible threat exists.What appears to worry some though, is the possibility of being mistakenly labeled as a suspect, criminal, terrorist, etc. People encounter many innocuous substances every day that could be construed as dangerous or even illegal. Stepping on a leftover marijuana stub without knowing it, could for example cause such a scanner to go off, as could applying fertilizer to the home garden prior to heading for the airport.Something else that seems to cause alarm is the fact that the technology behind the device appears to be sound, and in fact has apparently been done before. The difference this time is the speed at which it works; because of that, a single device could conceivably be used to scan every single person passing through an airport’s terminals, which means, that if deployed the days of singling out individuals for extra security measures would be over. If a person goes to an airport, they will be scanned, and most won’t even know it’s happened. The author of the article says an undersecretary at DHS has stated that the scanner will be ready for deployment within one or two years.

Hot Jupiter KELT16b offers unique opportunity for research

first_img Hot Jupiters are exoplanets that are roughly the size of Jupiter and that orbit their stars very closely. KELT-16b has been found to be within a radius of approximately 3 stellar radii above its host’s surface, and orbits its star in just .97 days—only five other transiting exoplanets have been found that orbit their star in less than one day. It has also been found to be approximately 2.75 times the mass of Jupiter and has an equilibrium temperature of approximately 2453 K. Such a short period, the researchers note, will allow scientists to watch and record a transit every day, providing a unique opportunity to learn more about the planet and others like it. Researchers are able to learn more about an exoplanet’s atmosphere when the exoplanet crosses its star—the starlight passing through can offer information not obtainable any other way. Also, the exoplanet’s large size should provide a relatively easy-to-study target.KELT-16b’s host star, KELT-16, is approximately 1,300 light-years from Earth and about 1.2 times the mass of our sun—it also has a companion red dwarf. The researchers also believe that its gravitational pull has coaxed KELT-16b closer for the past billion years, and likely will pull the exoplanet apart in as few as 550,000 years.The researchers believe study of the exoplanet by others working on different missions such as Hubble, Spitzer and the forthcoming James Webb Telescope will offer clues about such things as what happens at the boundary between day and night on such planets—such extreme temperature changes are likely to result in rain composed of vanadium and titanium oxide, for example. They also suggest that study of KELT-16b will help better understand how exoplanets evolve and move over time, including planet mortality.

DOI: 10.3847/1538-3881/153/3/97 , On Arxiv: https://arxiv.org/abs/1608.00618AbstractWe announce the discovery of KELT-16b, a highly irradiated, ultra-short period hot Jupiter transiting the relatively bright (V=11.7) star TYC 2688-1839-1. A global analysis of the system shows KELT-16 to be an F7V star with Teff=6236±54 K, logg⋆=4.253+0.031−0.036, [Fe/H] = -0.002+0.086−0.085, M⋆=1.211+0.043−0.046M⊙, and R⋆=1.360+0.064−0.053R⊙. The planet is a relatively high mass inflated gas giant with MP=2.75+0.16−0.15MJ, RP=1.415+0.084−0.067RJ, density ρP=1.20±0.18 g cm−3, surface gravity loggP=3.530+0.042−0.049, and Teq=2453+55−47 K. The best-fitting linear ephemeris is TC=2457247.24791±0.00019 BJDtdb and P=0.9689951±0.0000024 d. KELT-16b joins WASP-18b, -19b, -43b, -103b, and HATS-18b as the only giant transiting planets with P<1 day. Its ultra-short period and high irradiation make it a benchmark target for atmospheric studies by HST, Spitzer, and eventually JWST. For example, as a hotter, higher mass analog of WASP-43b, KELT-16b may feature an atmospheric temperature-pressure inversion and day-to-night temperature swing extreme enough for TiO to rain out at the terminator. KELT-16b could also join WASP-43b in extending tests of the observed mass-metallicity relation of the Solar System gas giants to higher masses. KELT-16b currently orbits at a mere ∼ 1.7 Roche radii from its host star, and could be tidally disrupted in as little as a few ×105 years (for a stellar tidal quality factor of Q′∗=105). Finally, the likely existence of a widely separated bound stellar companion in the KELT-16 system makes it possible that Kozai-Lidov oscillations played a role in driving KELT-16b inward to its current precarious orbit. (Phys.org)—A large international team of researchers has found that a hot Jupiter called KELT-16b is likely to offer a unique opportunity for research for many years to come. In their paper published in The Astronomical Journal, the team describes known characteristics of the exoplanet and why they believe it offers an opportunity to learn more about several aspects of exoplanet characteristics and development.

Bacteria found to produce compounds that activate sweet taste receptors in the

first_img More information: Robert J. Lee et al. Bacterial d-amino acids suppress sinonasal innate immunity through sweet taste receptors in solitary chemosensory cells, Science Signaling (2017). DOI: 10.1126/scisignal.aam7703AbstractIn the upper respiratory epithelium, bitter and sweet taste receptors present in solitary chemosensory cells influence antimicrobial innate immune defense responses. Whereas activation of bitter taste receptors (T2Rs) stimulates surrounding epithelial cells to release antimicrobial peptides, activation of the sweet taste receptor (T1R) in the same cells inhibits this response. This mechanism is thought to control the magnitude of antimicrobial peptide release based on the sugar content of airway surface liquid. We hypothesized that D-amino acids, which are produced by various bacteria and activate T1R in taste receptor cells in the mouth, may also activate T1R in the airway. We showed that both the T1R2 and T1R3 subunits of the sweet taste receptor (T1R2/3) were present in the same chemosensory cells of primary human sinonasal epithelial cultures. Respiratory isolates of Staphylococcus species, but not Pseudomonas aeruginosa, produced at least two D-amino acids that activate the sweet taste receptor. In addition to inhibiting P. aeruginosa biofilm formation, D-amino acids derived from Staphylococcus inhibited T2R-mediated signaling and defensin secretion in sinonasal cells by activating T1R2/3. D-Amino acid–mediated activation of T1R2/3 also enhanced epithelial cell death during challenge with Staphylococcus aureus in the presence of the bitter receptor–activating compound denatonium benzoate. These data establish a potential mechanism for interkingdom signaling in the airway mediated by bacterial D-amino acids and the mammalian sweet taste receptor in airway chemosensory cells.Press release Bitter taste receptors regulate the upper respiratory defense system, research shows Explore further Citation: Bacteria found to produce compounds that activate sweet taste receptors in the sinuses allowing infections (2017, September 7) retrieved 18 August 2019 from https://phys.org/news/2017-09-bacteria-compounds-sweet-receptors-sinuses.html © 2017 Phys.org Researchers have found that as many as 10 percent of the people living in America suffer from chronic sinus infections, leading to suffering due to the pain they cause and burdensome health care costs. Current treatments generally involve using antibacterial agents and/or drugs that reduce inflammation. But as the researchers note, such remedies are not always effective, and they do not prevent reoccurrence. Health scientists would prefer to find a way to prevent such infections rather than fighting them once established. To that end, research is ongoing regarding the nature of such infections and why some people are more susceptible to them than others. In this new effort, the researchers focused on interactions between bacteria and taste receptors, which are similar to those on the tongue, but which also exist on the surfaces of sinuses.Prior research has shown that when bitter taste receptors in the sinus are activated (when sensing the presence of bacteria), the immune system kicks in and starts fighting the bacteria. In contrast, when sweet taste receptors are activated, the opposite occurs.To learn more about what happens when Staphylococcus bacteria, frequently responsible for sinus infections, make their way into the sinuses, the group enlisted the assistance of patients with chronic infections, taking nasal swabs from each. The mucus from the swabs was then cultured in a lab where the bacteria was tested to see which types of amino acids it produced. The team found two sweet amino acids—D-Leu and D-Phe. The team did the same with Pseudomonas aeruginosa and found that neither of the two acids were produced. This suggested the two acids were used by the Staphylococcus bacteria to dampen an immune response. The team next grew human sinus cells in a petri dish and treated them with a chemical that stimulated the bitter taste receptors—they then added D-Leu and D-Phe. The team found that the acids prevented the receptors from sending out an alarm to instigate an immune response. They conclude by suggesting that Staphylococcus bacteria use the two sweet amino acids to dampen an immune response, allowing them to thrive in the sinuses.center_img Journal information: Science Signaling Credit: CC0 Public Domain (Phys.org)—A team of researchers affiliated with several institutions in the U.S. has found that a certain type of bacteria produces compounds that cause sweet taste receptors in the sinuses to activate—this in turn shuts off an immune response allowing the bacteria to thrive.

A slice of nature on canvas

first_imgIt isn’t everyday that the city gets to see the works of masters who are no longer among us. However, the works of one such, Gopal Ghose — widely known for his sketches of the infamous man-made famine of 1943 — is now displayed in the Capital’s National Gallery of Modern Art. Gopal Ghose, the exhibition, has been organised in association with Akar Prakar gallery, Kolkata to commemorate his birth centenary. Born in Calcutta, Ghose spent his childhood and adolescence shifting between Shimla, Benaras and Allahabad, since his father was recruited in the army. It was his father who spotted his artistic talents and gave him John Ruskin’s Elements of Drawing. Ghose’s pictorial language is inspired by Deviprosad Roy Chowdhury, under whom he studied at the Government School of Art, Madras. Also Read – ‘Playing Jojo was emotionally exhausting’He later shifted to a more contextually relevant pictorial diction during his association with the collective Calcutta Group. Ghose’s 1947 exhibition at the Exhibition Hall, Parliament Street, was appreciated by then Prime Minister Jawaharlal Nehru.‘To a Bengali, the name Gopal Ghose is certainly not alien. However, he is usually identified by a signature style that is marked by brilliant passages of pure hue and the elan of flourish in the calligraphic line. That this is but one aspect of his creative self, would be apparent through the range of  works in the present exhibition, which in itself is a selection from what is a much larger body spread out in various collections,’ says curator Dr Sanjay Mallik. Also Read – Leslie doing new comedy special with NetflixGhose’s pictorial language was was initially inspired to a great extent by the Bengal School diction, but his personal language transformed during the 1940s. His sketches of the infamous man-made famine of 1943 and the paintings executed during his association with the collective Calcutta Group testify his shift to a more contextually relevant pictorial diction that was oriented towards a boisterous exploration of the chromatic. However, in the decades that followed, Ghose’s works were more profound and had a serene note to them. ‘In the 1970s, the inward gaze crystallised further, as locale-specificity increasingly made space for the visionary, while his final paintings from 1980 returned once more to the flourish that transfixed fleeting impulsive impressions into momentous images,’ adds Mallik.Take a look at the paintings.

Abhimanyus bravado comes to Capital stage

first_imgHow well do you know Abhimanyu, the character from the epic Mahabharata? If not well, here is your chance to learn and watch him live on stage. The play Arjun Ka Beta, is a poetic rendition of the braveries of the warrior Abhimanyu, the son of Arjun and Subhadra.Directed by Atul Satya Koushik and organised by The Films and Theatre Society, the theatrical saga is of one hour 15 minutes duration. ‘The epic of Mahabharata, its characters and the hidden philosophies and interpretations behind its different incidents have always attracted the attention of young writers as well as its elements of this finds a tangible presence in today’s world,’ says Atul. Also Read – ‘Playing Jojo was emotionally exhausting’The play narrates the 13th day of the battle of Mahabharata, where Abhimanyu, inspite of being a skilled warrior gets killed while breaking and finding his way out of the chakravyuh. Later it goes on to show a dialogue between king Yudhisthira and the great warrior Bheeshama along with how Bheeshma’s inability to face Arjun who is unaware of his son’s death.How challenging was the part to create the mythological drama on stage along with precise sequence of activities and scheme of thoughts? Also Read – Leslie doing new comedy special with Netflix’It was a feat in itself. The actors did not have any scope of improvisations since the whole play has poetic verses instead of dialogues. The actors had to learn all the parts of poems by heart. Second, we had to understand the essence of Mahabharata through very limited resources and references avaialable in folk lores and texts. Third, portraying the characters with their typical behaviours and aura was a challenge too,’ Atul points out.The play also has a philosophical value to it with respect to how the chakravyuh is presented. ‘The chakravyuh is not only instrumental in killing Abhimanyu but it is metaphorical too. It depicts our life and our continuous striving through it. The chakravyuh is a circle of life and the only way out is to fight constantly untill you are dead,’ says Atul.Arjun ka Beta has been performed before in July 2011 in Mumbai and is now gearing up for Delhi audience to watch. ‘Mythologies definitely have an interest value to them and I am hoping that we will see a grand audience for it. Though I still have to take this play far and wide with its reach,’ concluded Atul.DETAILAt: Sri Ram Centre, Safdar Hashmi Marg, Mandi HouseWhen: 6 AprilTimings: 7 pm onwardsTickets: Rs 300, 200, 100 and 50last_img read more
