The hunt for hot nuclear matter (PhysOrg.com) — Later this year, the world’s largest and most powerful particle accelerator, the Large Hadron Collider near Geneva, Switzerland, will begin operating, sending beams of protons hurling around circular tracks in opposite directions at nearly light-speed and then forcing them to collide, producing a spray of energy and matter. Explore further Scientists’ hopes are high for the LHC, with many yearning that its detectors will record evidence of undiscovered theorized particles and new physics. In that respect, a group of physicists considers a new possible discovery: a new dimension. At the LHC, the proton collisions will be powerful enough to probe incredibly minute size scales, perhaps minute enough to open a tiny new dimension.”While the LHC may uncover what appears to be an extra dimension, it could really be a hologram of some more complicated physics theory,” said physicist Veronica Sanz of Boston Univeristy and York University in Ontario, Canada, to PhysOrg.com. Sanz is one of three physicists involved in the study.By “hologram,” Sanz and her colleagues aren’t referring to a flat image that appears three dimensional. Rather, in the context of particle physics, holography imagines an extra dimension to handle the calculations of strongly interacting systems, like LHC collisions. Added physicist Adam Martin of Yale University, “LHC could discover a new type of strong interactions wildly different from the strong nuclear force we already know from the Standard Model.”The strong nuclear force is one of the four fundamental physics forces and is what keeps atomic nuclei together, mediated by gluons. The other three forces are the electromagnetic, gravitational, and weak forces. The strong, weak, and EM forces, and the particles that experience them, are all described by a sweeping physics theory known as the Standard Model (gravity is ignored because it is so weak by comparison).But the Standard Model isn’t quite complete: One particle, the proposed “Higgs boson,” has yet to be discovered. It is the missing piece of the Standard Model and perhaps the “Holy Grail” of LHC results. If found, it could tell scientists about the origins of mass itself, and why matter can be made of elementary particles that are essentially massless. The Higgs, they think, is responsible for assigning masses to those elementary particles.But the Higgs may not exist, or may not be found. And if not, Standard Model calculations become unwieldy, as only with the Higgs do the calculations make sense. But a new physical dimension, if only an imaginary one, could make such calculations easier.”For all we know, extra dimensions may be nature’s way of computing the masses of particles,” says the study’s corresponding scientist, Yale University physicist Johannes Hirn.This research is published in the May 23, 2008, online edition of the Journal of High Energy Physics.Citation: Johannes Hirn et al JHEP 05 (2008) 084Copyright 2008 PhysOrg.com.

Researchers working at the US Smithsonian Tropical Research Institute on Barro Colorado Island in the Panama canal have found the ants glide back to the tree by flipping in mid-air and gliding backwards, seeing where they are going by looking between their legs, and steering using their unusually long hind legs. The elongated rear legs of the centimeter-long ants also help them latch onto the tree when landing.

Scale bar = 1 mm. © 2010 PhysOrg.com Leader of the research team, Stephan Yanoviak of the University of Arkansas at Little Rock, said it was important for the ants to avoid falling to the leaf litter on the ground or into water because they would most likely be eaten. Their gliding abilities allow them to steer back to the tree (usually the tree they fell from), and then climb back up to the safety of the nests built into the branches and trunk at the top of the trees.The study also learned that if the ants are attacked by predators they release an alarm pheromone that warns nearby ants to jump off the tree to safety.Yanoviak said studying the ant’s control of its fall is relevant to understanding the behavior, and also the flight of insects generally. The study is published in the journal Proceedings of the Royal Society B. Play This video shows a control drop (to indicate a straight fall) followed by three different C. atratus workers. Ant #4 exhibits a typical controlled descent. It starts to head away from the tree, but then makes a quick 180-degree turn and glides to the trunk. Ant #5 makes a nice recovery from a tumbling fall. Ant #6 was caught by an unexpected breeze coming from the top right of the screen, but was able to adjust its descent in the form of a long curving glide that ends on the leeward side of the tree. Credit: Stephan Yanoviak. The scientists studied the ants by collecting some ants and painting them with white nail polish to make them easier to spot. They plucked one or two legs off some of the ants, then climbed to the top of the trees and dropped the ants from the treetops and videoed their fall. They then verified their findings in the laboratory, where they used a high-speed video camera. The results showed the ants could still glide back to the tree even if both rear legs were removed, but they were not able to steer as well. Intact ants were able to land on a tree trunk over 90 percent of the time; ants with the mid legs removed succeeded less than 70 percent of the time, but in those with hind legs removed the success rate was reduced to about 40 percent.

Explore further In their search to find new ways to cram more electronics onto the same size chips, researchers have turned to FETs. Transistors on chips are the parts that control the flow of electricity—figuring out a way to make them smaller is a vital part of keeping Moore’s Law alive. One way to do this is to do away with wires and instead use nanowires. However, because of their small size, nanowires aren’t capable of carrying enough current to do the work necessary on a chip. To get around that, researchers have tried creating bundles of nanowires; but thus far, the gates to control them have been too unwieldy. In this new effort, the researchers tried a different approach.First they created a forest of 225 nanowires by etching a slab of silicon—the bottom half of each nanowire is submersed in a material that serves as a source. Just up from that base, the researchers applied a chromium layer wrapped all the way around the nanowire to serve as the gate. Above that was another layer of material that serves as the sink. This simple design allows each nanowire to be controlled by its individual gate, and the researchers report the thickness of the gate is what makes it all work. At 14nm, the gate can be made short enough to continue to allow for the control of the current. The result is a transistor that thus far appears to be a workable way for increasingly more circuitry to be added to a computer chip. More information: Vertical nanowire array-based field effect transistors for ultimate scaling, Nanoscale, 2013,5, 2437-2441. DOI: 10.1039/C3NR33738CAbstractNanowire-based field-effect transistors are among the most promising means of overcoming the limits of today’s planar silicon electronic devices, in part because of their suitability for gate-all-around architectures, which provide perfect electrostatic control and facilitate further reductions in “ultimate” transistor size while maintaining low leakage currents. However, an architecture combining a scalable and reproducible structure with good electrical performance has yet to be demonstrated. Here, we report a high performance field-effect transistor implemented on massively parallel dense vertical nanowire arrays with silicided source/drain contacts and scaled metallic gate length fabricated using a simple process. The proposed architecture offers several advantages including better immunity to short channel effects, reduction of device-to-device variability, and nanometer gate length patterning without the need for high-resolution lithography. These benefits are important in the large-scale manufacture of low-power transistors and memory devices.via IEEE Spectrum Journal information: Nanoscale (Phys.org) —Two French researchers, Guilhem Larrieu and Xiang‑Lei Han, may have succeeded in possibly setting back the date to which Moore’s Law would no longer apply by creating a new kind of nanowire Field-Effect Transistor (FET). In their paper published in the journal Nanoscale, the two describe how they built a “gate-all-around” made of 225 nanowires, each with its own 14nm-thick chromium layer that serves as a gate.

Should the new design pan out, it won’t keep Moore’s Law alive forever, of course. One day, researchers will reach a point where it’s no longer possible—due to the laws of physics—to add more processing power to a computer chip. As such, new research will necessarily be focused on ways to build smarter computers using different ideas, rather than new materials. © 2013 Phys.org This document is subject to copyright.

Methane has been identified as a greenhouse gas, one that is perhaps more of a problem even than carbon dioxide because it traps more heat (some studies have suggested 25 times as much)—fortunately, not nearly as much of it is emitted by humans into the atmosphere. It makes its way into the atmosphere due to animal flatulence and some industrial processes. It is also a byproduct at gas wells, where it is generally burned.Methanol, on the other hand, has been considered a good alternative to gasoline for use in automobile engines. It is currently made using a variety of techniques and basic materials including coal, natural gas and even municipal waste. One approach is to use high-pressure and high-temperature oxidation of the gas, but most consider such methods too technically challenging to use in places such as drilling sites. In this new effort, the researchers describe a simpler way to make methanol using water (as an oxidant instead of oxygen) and methane.In their process, water is used to oxidize methane over a bed of copper containing zeolite—the unique structure of the mineral lets the water behave as an oxidant. The team claims the process is 97 percent efficient, emitting only methanol and hydrogen. The method, the researchers note, is simple and easy enough that it could be used at drilling sites and the resulting methanol could be used as a liquid fuel or as an ingredient in making resins or plastics. The hydrogen could be used in any number of ways, including in fuel cells.The researchers acknowledge that their work was a proof-of-concept study, which means that it is still not clear if their technique could be modified to convert methane on a very large scale in a cost-efficient manner. (Phys.org)—A team of researchers from the Paul Scherrer Institut and ETH Zurich, both in Switzerland, has developed a one-step process that uses water to convert methane to methanol. In their paper published in the journal Science, the group describes their technique, noting that in addition to offering a simple and relatively cheap way to make methanol, the only other byproduct is hydrogen.

DOI: 10.1126/science.aam9035AbstractDirect functionalization of methane in natural gas remains a key challenge. We present a direct stepwise method for converting methane into methanol with high selectivity (~97%) over a copper-containing zeolite, based on partial oxidation with water. The activation in helium at 673 kelvin (K), followed by consecutive catalyst exposures to 7 bars of methane and then water at 473 K, consistently produced 0.204 mole of CH3OH per mole of copper in zeolite. Isotopic labeling confirmed water as the source of oxygen to regenerate the zeolite active centers and renders methanol desorption energetically favorable. On the basis of in situ x-ray absorption spectroscopy, infrared spectroscopy, and density functional theory calculations, we propose a mechanism involving methane oxidation at CuII oxide active centers, followed by CuI reoxidation by water with concurrent formation of hydrogen.
The scientists characterized optical traits of the cavity-coupled plasmonic system in the study and categorized them by geometrical features relative to the wavelength of incident light (λinc). To demonstrate this effect, two devices were primarily defined and simulated in the study led by the research group to operate in the MWIR and LWIR atmospheric transparency windows. The multispectral reflectance spectra of the respective surfaces were calculated as a function of the diameter of the hole using the FDTD method.When the incident light was considerably larger than the pattern, the system behaved as a metallic plane or mirror. As the incident light decreased, extraordinary light transmission occurred through the subwavelength hole-disk array, due to induced plasmon resonance, coupling the electromagnetic wave into the cavity. As the incident light became comparable to the array’s structural dimension, the system supported higher-order plasmonic and interference resonances due to the onset cavity-internal diffraction. Using the parameter study, Franklin et al. identified two possible routes to achieve infrared encoding; (i) the diameter of holes and (ii) the relief depth—while maintaining uniform visible absorption. When the cavity-coupled plasmonic system was excited at resonance, coherent interactions between photons and the free electron density within the metal produced collectively charged oscillations known as surface plasmons. High-density charge localization and microcurrents resulted from the interactions on the edges of the metallic elements, whose energy dissipated by ohmic loss. By varying the system’s parameters, the scientists encoded images on the surface within a desired spectral range, while these images did not appear visible within others. For example, an image encoded within the mid-wave infrared (MWIR) window, appeared as a grayscale image when viewed through a MWIR camera, although the appearance within the visible range and long-wave infrared (LWIR) regime remained a constant color. By varying the laser writing parameters (power and speed) of the master writing process, the scientists obtained a variety of hole diameters for the mid-wave infrared (MWIR) and long-wave infrared (LWIR) devices. Depending on the angle of incident light and viewing angle, when viewed by the eye or using a visible regime camera, the encoded surface appeared as a uniform block of color. Meanwhile the infrared camera showed the encoded grayscale images at a resolution depending on the surface plasmonics.The scientists conducted visible and infrared spectrometer measurements of the fabricated plasmonic systems. The infrared resonant surfaces were imaged using cameras designed for their respective bands of operation. A cooled indium antimonide detector was used to view the MWIR surfaces and an uncooled VOx microbolometer camera was used to view the LWIR surface. Dipolar coupling between the array of holes/disks and their interaction with optical cavity dictated the infrared response. Diffraction in to Fabry-Perot cavity modes dominated the visible regime. Grayscale images and data were encoded into the surfaces by mapping the diameter of holes of the plasmonic system to respective pixels.

Recent advances in nanotechnology and materials science and their combined capacity to develop controlled geometries at the nano-scale continue to evolve, as observed with optical properties of amplitude, phase and wave fronts for materials in optics. Although researchers have focused on individual frequencies and wavelengths, few studies have attempted to control fundamental properties across multiple electromagnetic frequency regimes. For instance, multispectral systems can establish new surfaces with combined functions, such as reflective multilayers that selectively absorb and emit infrared light in transparent atmospheric windows for thermal management. Similarly, plasmonic filters with tunable resonance can be used for multispectral color imaging. These concepts can be applied to achieve camouflage and anti-counterfeiting techniques. a) Schematic of the cavity-coupled plasmonic device consists of a backmirror, an imprinted array of holes in a polymer, and a second evaporation of gold to create disks and a perforated film. b) A false-colored scanning electron microscope image of the plasmonic system and a schematic with the various structural parameters. c) An encoded surface where pixel data are mapped to structural features of the plasmonic system.

Credit: Light – Science & Applications, doi: 10.1038/s41377-018-0095-9. Resonances in such systems occur as excited electric and magnetic multipole modes that depend on the geometries and dimensions of constituent materials due to inherent features of plasmon hybridization and plasmon-phonon-coupling. Such traits can be effectively used to engineer optical surface properties of a material. However, attempts to control structural parameters and accommodate a specific spectral regime can influence higher-order resonances in lower-wavelength ranges, resulting in a lack of independent control of optical character in specific spectral regions. In a recent study, a new device employed plasmonics to control a variety of wavelengths of light using a multilayer cavity-coupled nanostructured system. The plasmonic system maintained continuously tunable absorption throughout the mid-wave (3-5 µm) and long-wave (8-12 µm) infrared (MWIR and LWIR) atmospheric transparency windows, while maintaining near-invariant visible properties. The device was designed and developed by Daniel Franklin and colleagues in the Department of Physics and fabricated with a dielectric layer patterned with regularly-spaced nano-sized holes. By design, the nanostructures were sandwiched between a reflective metallic mirror and a thin upper gold layer with holes corresponding to the middle disc. Functionally, the spectral response of the multilayered cavity-coupled nanostructure depended on interactions among plasmonic resonances, diffraction and cavity feedback. The resonance mode of each regime was defined and explored using finite-difference time-domain (FDTD) numerical simulations. The parameters were identified and varied to create an experimental infrared (IR) color palette. Such images were made visible with IR cameras but were concealed in the visible domain by consistent pixel-to-pixel plasmonic absorption and diffraction. The study used a multispectral engineering setup to demonstrate cavity-induced plasmonics for applications in camouflage and anti-counterfeit technologies. The work is now published on Light: Science and Applications. Two systems are explored for operation in the mid wave infrared (MWIR) and long wave infrared (LWIR) transparency windows. a) Schematic of the plasmonic device designed for the MWIR and b) corresponding finite-difference time-domain (FDTD) simulations of reflectance as a function of hole diameter. c) A schematic of the LWIR device and d) the equivalent FDTD sweep of hole diameters.

Coupling of plasmonic and optical cavity modes in quasi-three-dimensional plasmonic crystals, Nature Communications (2011). DOI: 10.1038/ncomms1487 The scientists quantified diffraction efficiency in the study for the MWIR and LWIR devices as a function of hole diameter using FDTD. Results indicated that devices could be tuned for different wavelengths; primarily through the infrared transparency windows by modifying the hole/disk diameter and maintaining pixel-to-pixel brightness in the visible domain. The encoded information was not ‘invisible’ for different wavelengths, in contrast the dimensions of the plasmonic hole-disk system exceeded the diffraction limit of the visible light. Individual features were visible with high magnification objectives. The study combined ease of fabrication and compatibility on flexible substrates to engineer the device architecture. The results will lead to new plasmonic surfaces with multispectral functions to encode information. As a proof-of-principle, Franklin et al. encoded images and data onto material surfaces and observed them using infrared and visible cameras to demonstrate the potential of the cavity-coupled plasmonic system. In the technique, the scientists created a map between diameters of a given pixel and grayscale values of the surface to view through infrared camera imaging. The image was first encoded using direct laser writing onto a master template polymer that was used to fabricate the nanostructured surface using nanoimprint lithography (NIL). Before and after the NIL process the three-layered metallic cavities produced were imaged using scanning electron microscopy (SEM) for surface characterization.

As a writer I am also happy when I have completed a story or poem or essay and feel pleased with it,” he writes. Also Read – Leslie doing new comedy special with NetflixFeeling “pleased” is imperative, according to him. “Failed creations make me unhappy,” he writes. Bond’s first advice towards achieving happiness is, “To find happiness, look halfway between too little and too much,” It is followed by an African proverb that draws an analogy where, “Happiness is as good as food.” He goes on to tell his readers from his experience how for most of his life, he relied on his instinct rather than intelligence and found himself in a “modicum of happiness.” “Life hasn’t been a bed of roses. And yet, quite often, I’ve had roses out of season,” writes an optimistic Bond. The book is peppered with the words of wisdom by stalwarts from different walks of life – authors, political leaders, scientists. Some of them include – Jane Austen, Dalai Lama, Charlotte Bronte, Osho, Pablo Neruda, Sylvia Plath, Stephen Fry, Benjamin Franklin, Leo Tolstoy, Oscar Wilde, William Shakespeare, and Rumi among others.According to the author, who has written extensively for children, a sense of satisfaction obtained from the vocation one practises is indispensable, for it is also a source of happiness. The author seems to have consciously left a couple of empty pages titled “Notes” after every few entries, perhaps for the reader to jot down their own musings on happiness and add to the book.

I got my period. As many of you know, I have PCOS, so to get your period is such an amazing feeling. I immediately ran to my sanitary napkin stash, but found I had run out of them.”She quipped via a social media post: “Instead, I saw my mom, dad, grandmother and my building’s secretary posing with them and taking pictures. I asked them what they are doing with my pads, and they said, ‘Shut up silly girl, we’re taking part in a movement that will change the course of history. We’re going to make periods a taboo a thing of the past! The Padman Challenge will empower women! Don’t forget to use the hashtag otherwise you’re not empowering anybody. “I felt so empowered and inspired and I wanted to do the challenge too, but at this time everyone had thrown away the opened pads and I continued to bleed through my clothing.”She took her own challenge by posting an image in which she holds up a notepad that reads: “Don’t waste sanitary napkins on stupid marketing gimmicks. Trust me guys it’s the best feeling to not have access to pads when you’re bleeding and the Pad Man challenge is all that is needed to destigmatise a woman’s period. Kudos to champion of all causes Akshay Kumar and his amazing marketing team for championing this cause.”Her sarcasm didn’t end there as she concluded her message with: “Pads are just selfie accessories any way!”Comedienne Mallika Dua also poked fun at the #PadManChallenge.In a series of Instagram stories, she wrote: “Always remember. Each time you feel weak, each time you feel lesser than your equals, each time you feel you’ve been made to feel lesser for no reason and that the fight has just about begun, when you feel society and the government have not given you your due, hold up a sanitary pad and post a picture of it on Instagram. You will feel empowered. So empowered. Bye.”One Twitter user wrote: “Sonam Kapoor is against her own film’s marketing gimmick. Hahahaa. PadManChallenge.” The user shared a tweet that was liked by Sonam. It read: “Cute how Bollywood celebrities start doing stupid trends like #PadManChallenge but automatically lose their spine when asked to take stand on ‘Padmaavat or when Swara was being slut shamed. Such hypocrites!”A Facebook user tired of the challenge, suggested: “If you really want to do something, buy a packet of pads and give it to someone who can not afford it. That will be the real #padmanchallenge.”Akshay has maintained that the film has sparked discussions about the subject, and “there will be a day when it will change”.Miss World Organisation CEO Julia Morley is here as part of a world tour led by Miss World 2017 Manushi Chhillar.”We should know that it’s no use when we can do a lot of talking and we don’t have the action. That’s what scares me. One has to put your money where your mouth is, and make sure it continues,” she said.
