We hope that by studying a spinning weightless water droplet, something easily observable with the naked eye, we may help other researchers trying to understand much stranger objects such as black holes and atomic nuclei.”Scientists have been intrigued with spinning water droplets going back to 1863, when the Belgian physicist Joseph-Antoine-Ferdinand Plateau suspended a drop of olive oil in a water-alcohol mixture of the same density. He used a rotating shaft to spin the oil droplet and found that the droplet changed shape: it became flattened at the poles, and bulged at the equator (which, incidentally, is similar to the shape of the Earth due to its rotation). More recently, theoretical investigations have revealed that a droplet’s shape should change depending on its rotational velocity, assuming a series of shapes as it spins faster and faster. The reason for this distortion, the scientists explain, is that a droplet seeks the lowest energy state for a given rotational frequency. Specifically, it begins as a sphere when at rest, and then progresses into a two-lobed “peanut” shape.Theory predicts triangular (three-lobed) and square (four-lobed) shapes at higher rotational velocity, but these shapes should be unstable and should decay into the ellipsoid shape. Yet previous experiments on acoustically levitated droplets have shown that it’s possible to stabilize a spinning triangular shape. However, in these experiments, the droplet’s shape oscillates strongly as it spins, so the equilibrium shape is not clearly observed in these demonstrations.

Researchers Richard Hill and Laurence Eaves of the University of Nottingham in the UK have recently designed an experiment that exploits the possibilities of a spinning water droplet to the fullest. Their technique overcomes previous challenges, such as completely removing the effects of gravity, and minimizing the viscous drag caused by spinning in order to stabilize the droplet. Their study is published in the December 5th issue of Physical Review Letters.

How plague pathogens trick the immune system By magnetically levitating water droplets, and using a “liquid electric motor” technique to spin them, researchers can investigate how the droplets change shape. Rather than being just a curious experiment, the results could provide insights into systems that cannot be controlled in the laboratory, such as black holes and atomic nuclei. In the current study, Hill and Eaves used techniques that, for the first time, allowed them to see the equilibrium three-lobed shape clearly. To do this, they first found an innovative way to create a gravity-free environment, by using diamagnetic levitation. Because water is diamagnetic, the electrons in the water molecules rearrange themselves in the presence of an applied magnetic field, creating small currents. These currents oppose the applied magnetic field by Lenz’s Law, and generate a strong enough magnetic repulsion to balance the force of gravity, so that the droplet levitates. Once the droplet is weightless, the researchers used a novel “liquid electric motor” technique to spin the droplet. They inserted two thin wire electrodes in the droplet, and passed a current through the wires, creating a torque on the droplet that causes it to rotate. By adjusting the current, the researchers could easily control the frequency. More importantly, the flow of water past one of the electrodes sets up small waves on the surface of the droplet, and these side currents can help stabilize the droplet, preventing the many-sided shapes from decaying into an ellipsoid. The researchers found that the behavior of the peanut and triangular shapes agreed well with theoretical predictions.The researchers hope that understanding spinning water droplets could provide insights into other systems that have analogies with fluids. For instance, gravity and the strong nuclear force behave in a similar way to surface tension in that they are all cohesive forces. Understanding the surface tension in a spinning water droplet, then, could help scientists understand how astronomical bodies, as well as atomic nuclei, are held together.“Cosmologists believe that the event horizon of a black hole behaves as if it possesses surface tension, like a droplet,” Hill explained. “The stability of the shapes of a spinning droplet could tell us some new things about the stability of the event horizon of a spinning black hole.“The shapes of other more familiar astronomical objects such as planets and asteroids, which are held together by their own gravity, rather than by surface tension, also follow a similar pattern to that of the droplet,” he continued. “For example, recent observations of asteroids in the Kuiper belt beyond Neptune have revealed objects with an ellipsoidal shape, probably due to their rapid spin, similar to that observed in our experiments.”The scientists added that, in the liquid drop model of the atomic nucleus, recent work has been done investigating the stability of very rapidly spinning atomic nuclei. Researchers can use the behavior of a liquid droplet to gain insights into this problem, as well.In the future, the scientists plan to further investigate the possibilities of magnetic levitation.”We’re investigating whether magnetic levitation can be used to explore what happens to biological organisms, such as plants, in a weightless environment like that of space,” Hill said. “We can keep objects levitating for months using our magnet – the information we get from long-term experiments could be extremely useful for future missions to the Moon or Mars. However, like Plateau, studying floating oil droplets in 1863, we may have to wait several decades before this work finds applications!”Watch videos of the spinning water droplet as it changes shape at netserver.aip.org/cgi-bin/epap … =E-PRLTAO-101-065848 (Supplementary movies.zip).More information: Hill, R.J.A. and Eaves, L. “Nonaxisymmetric Shapes of a Magnetically Levitated and Spinning Water Droplet.” Physical Review Letters 101, 234501 (2008).Cardoso V. “The many shapes of spinning drops.” Physics 1, 38 (2008) physics.aps.org/articles/v1/38 Copyright 2008 PhysOrg.com.

Study clarifies the role of the leaving group in gasphase bimolecular reaction

first_imgOne of the first reaction mechanisms students learn in undergraduate organic chemistry is the SN2 reaction. Named because it involves the collision of two molecules, its energy barrier is related to the nucleophile, the solvent, and the leaving group. Exactly how the leaving group influences what is going on at the molecular level, however, remains elusive. © 2015 Phys.org Study reveals peculiar mechanism of radical addition-elimination Using reaction cross-beam scattering and velocity map imaging combined with simulation studies a gas-phase SN2 reaction, F- + CH3Cl-, and comparing it to prior studies of F- + CH3I, Martin Stei, Eduardo Carrascosa, Martin A. Kainz, Aditya H. Kelkar, Jennifer Meyer, Istvan Szabo, Gabor Czako, and Roland Wester from the Institute for Ion Physics and Applied Physics, Universitat Innsbruck in Austria, the Institute of Chemistry, Eotvos University in Hungary, and the University of Szeged in Hungary have determined that the leaving group has a strong influence on reaction dynamics by influencing the orientation of the reactants. Specifically, they found that while both the chlorine and iodine reactions form a hydrogen bonding complex at the entrance channel, key differences cause one to be a direct rebound mechanism while the other is an indirect mechanism. Their work is reported in Nature Chemistry.Reaction dynamics is the study of individual molecular collisions. While kinetic theory describes a mechanism based on aggregate behavior, reaction dynamics looks at individual particles. Reaction dynamics answers questions such as “Do the reactants need to collide in a certain way in order for a reaction to occur?” To answer questions about particular collisions, reaction dynamics studies must be conducted in the gas phase. This particular study looked at collisions using ion beams to control reactant velocity and TOF-MS to measure product velocity. In the SN2 reaction F- + CH3Cl- à CH3F + Cl-, fluorine serves as the nucleophile, which engages in a “nucleophilic attack” on CH3Cl, and chlorine serves as the leaving group. This reaction occurs through an orchestrated process that, on the molecular level, shows that fluorine must collide directly with the electrophilic carbon, rather than the chlorine or hydrogens. Lower velocities did indicate an indirect complex-mediated mechanism, but for most velocities, this reaction undergoes a direct rebound mechanism. This is evidenced from scattering data that shows the chlorine leaving scattering in the backward direction. Lower velocities showed isotropic scattering. Even though there is evidence of a hydrogen bonding complex at the entrance channel, this reaction is not a slow, complex-dependent mechanism. The hydrogen complex, however, may affect reactant orientation. This is not the case for the analogous reaction with iodine as a leaving group: F- + CH3I- à CH3F + I-. Prior studies showed that while this reaction does display some backscattering, it seems to have a greater isotropic distribution and higher internal energy at most velocities, indicating an indirect complex-mediated mechanism. For this reaction, the collinear entrance channel plays a more important role in lowering the reaction energy barrier than forming a hydrogen complex. In other words, the reactants may impact each other in various ways.Simulation studies confirmed the experimental results of the chlorine reaction. Additional simulation studies showed that mass differences do not play a role in the differences between these reactions mechanisms, and impact parameter measurements indicate that reactant orientation is much more efficient in the case of the chlorine reaction compared to the iodine reaction. This is likely due to CH3Cl having a larger dipole moment compared to CH3I, which causes the fluorine ion to preferentially impact CH3Cl in a direct rebound orientation.This study shows that given by comparing seemingly analogous gas-phase SN2 reactions, at the molecular level, their reaction dynamics are distinctly different. These differences are due to properties of the leaving group that are beyond differences in mass, and likely have to do with molecular orientation upon impact.

How to Maybe Be Less Indecisive or Not

first_imgIf you’re like me, even the simplest decisions can make your pulse race. And when it comes to big, life-altering choices, the need to get it right (because life is short!), combined with ever-looming F.O.B.O. (fear of better options), can cause a state of near paralysis. Should you order tacos or tikka masala? Stay at the hotel with the free breakfast or the one with all the succulents? Melt into the couch or drag yourself to happy hour? While this abundance of choice is a result of incredible privilege — not everyone has the freedom to select where they work or live, or how to spend their time or money — it can still be overwhelming. As Barry Schwartz, the author of “The Paradox of Choice,” said, “I’m reasonably confident we’re operating with far, far more options in most parts of our life than we need and that serve us.”center_img Here are five strategies for spending less time agonizing over decisions and more time appreciating the results: Read the whole story: The New York Timeslast_img read more

Body of wife found hanging at rented flat near Haldirams husband held

first_imgKolkata: Baguiati police station has arrested a person for allegedly abetting his wife to commit suicide.According to police, Antara Sarkar Acharjee’s body was found inside a room of his hired flat at a housing complex near Haldiram’s on Wednesday. Her husband claimed that he does not know why his wife committed suicide. On Sunday, Antara’s father Ranjit Acharjee, a resident of Khalisakota Pally near Birati, lodged a complaint against his son-in-law Surajit Sarkar alleging that he used to torture his daughter. Also Read – Rain batters Kolkata, cripples normal lifeSources informed that Ranjit said her daughter and Ranjit were married in February 2006. It was alleged that after a few years of their marriage, Surajit started torturing Antara as she could not give birth to a child.

The body has been set for an autopsy which might throw some light on the cause of her death.last_img read more

Happy songs trigger pleasant memories

first_imgListening to happy or peaceful music can make pleasant memories spring into your mind, while sad or scary tunes may invoke negative emotions, a new study has found.Researchers from McGill University in Canada studied 48 participants, who were made to listen to 32 newly composed piano pieces unknown to them in 30 seconds.The pieces were grouped into four retrieval cues of music, happy (positive, high arousal), peaceful (positive, low arousal), scary (negative, high arousal) and sad (negative, low arousal). Also Read – Add new books to your shelfParticipants were then asked to recall events in which they were personally involved, that were specific in place and time and that lasted less than a day. As soon as a memory came to mind, participants pressed a computer key and typed in their accessed memory.The researchers noted how long it took participants to access a memory, how vivid it was and the emotions associated with it. The type of event coming to mind was also considered and whether for instance it was quite unique or connected with an energetic or social setting. Also Read – Over 2 hours screen time daily will make your kids impulsiveMemories were found to be accessed most quickly based on musical cues that were highly arousing and positive in emotion and could therefore be classified as happy.A relationship between the type of musical cue and whether it triggered the remembrance of a positive or a negative memory was also noted. The nature of the event recalled was influenced by whether the cue was positive or negative and whether it was high or low in arousal.”High cue arousal led to lower memory vividness and uniqueness ratings, but both high arousal and positive cues were associated with memories rated as more social and energetic,” said Signy Sheldon from McGill University. Researchers found that a greater proportion of clear memories were recalled when highly arousing positive cues were played in a blocked fashion.Positive cues also elicited more vivid memories than negative cues. In the randomised condition, negative cues were associated more vividly than positive cues, researchers said. The study was published in the journal Memory and Cognition.last_img read more

Experts list some more options on revamping your interiors with rugs: By popular belief, rugs are meant to be used on the floor under your furniture, but the new trend is to use them as wall art, especially semi-geometric patterns.

A smaller rug over a bigger one or a printed rug over a solid-coloured one would be ideal. But be wary of layering too many “warring” patterns in a room; the key is to complement the palette of the room. Use a rug as a focal point in a room. Pick a colour from the rug and reflect it throughout . It’s easier to nip choices in a room to complement the rug, rather than the other way around.

Opt for a large rug with a soft feel underfoot to place under your bed to completely change the look of your bedroom spaces. Rugs aren’t just for winter. Opt for a summer-appropriate soft update in calming hues, geometric pattern, or lighter texture to make your scheme work for the current season and beyond. In larger rooms, use an understated design with a border to ground the space together.

Grace Kellys Wedding Gown – The Most Popular Bridal Dress of All

first_imgThe wedding of Hollywood actress Grace Kelly and Prince Rainier of Monaco took place on April 19, 1956, in Monaco. To this day, it is considered as the most stylish, dreamy wedding on record. What is most remembered about this royal wedding is Grace Kelly’s wedding dress. It is the most popular wedding dress in the world and continues to inspire brides and designers for creating new models.It was assumed that Edith Head, a close friend of Kelly and a famous American costume designer, would be asked to design the wedding dress.Grace Kelly Wedding. Photo by Caroline Picard CC BY-SA 4.0However, Kelly asked Helen Rose, a double Academy winning designer who worked in the wardrobe department of MGM.Helen Rose worked closely with Kelly in designing the dress that used over 400 yards of fabric, including a 125-year-old rose point Brussels lace.L. to R. : Annabella Levy (hairdresser), Elizabeth Taylor, and Helen Rose (costume designer) on the set of Rhapsody (1954) – publicity still.The dress broke down into ten parts, all created piece by piece. The skirt was made of ivory faille with three petticoats: a smoothing petticoat, ruffled petticoat, and foundation petticoat. The gown was made of 100 yards of silk net. There was also the skirt support, the under bodice, and the lace bodice which came with a slip.The veil, 90 yards long, was made of very fine, lightweight netting, and it was specially designed to keep her face as visible as possible. As an A-list movie star, Kelly’s wedding attracted the attention of 30 million viewers who observed from afar, while the ceremony was attended by 600 guests.Princess Grace Kelly in her wedding dress at Prince’s Palace.

Finally, a train insert and silk faille cummerbund completed the outfit.Instead of lots of flowers, in the style of devout mid-20th-century brides, Kelly carried a Bible. She received the book as a gift which was later embellished with silk, lace, and pearls at MGM. She also carried a petite bouquet of lilies-of-the-valley.Princess Grace and Prince Rainier before Pope John XXIII at Saint Peter’s Basilica in Rome, 1959.At the time, the estimated manufacturing and material cost of Kelly’s bridal dress was $7,266, without the designer’s fee, and the fee for the 30 seamstresses that worked for six weeks.And it was the wedding gift from MGM Studios to their beloved actress Kelly Grace.Since Prince Rainier’s height stood close to Kelly’s height, she wore just 2½-inch heels. The pumps were designed by David Evins, the “King of Pumps” and the “dean of American shoe designers.” He added lace and seed pearls. In the left shoe, Evins embossed Kelly’s name and his own in the right shoe. He also put a copper penny in the right shoe for good luck.(Photo by 3777/Gamma-Rapho via Getty Images)The wedding involved two separate celebrations – the civil ceremony and the church marriage held on consecutive days. Kelly wore her wedding dress on the second day, while at the civil ceremony she wore a pink floral ensemble, accessorized with a Juliet cap. Again, the design was by Helen Rose.Two days before the wedding, details of the dress were disclosed and it was described in the media as “serenely regal.”There was one columnist who wrote that Kelly’s dress was beautiful but hardly an outstanding one. However, the consensus was that the gown was magnificent. And it still is.Read another story from us: Vintage Supermodels – “Glamorous” Dresses in the 1860sToday, the dress is owned by the Philadelphia Museum of Art. In 2006, for the celebration of the 50th anniversary of Grace Kelly’s wedding, the museum displayed the dress through the months of April and May, later reporting that it was probably the most popular exhibition in the Museum.last_img read more

LSU puts Les Miles out to pasture

first_imgLes Miles has chewed on his last blade of grass as head coach of the LSU football team, after 12 years leading the program. Today, the school announced it has officially fired “The Hat”, and his offensive coordinator Cam Cameron, following LSU’s 18 -13 loss to a mediocre Auburn team.The loss dropped LSU to a disappointing 2 -2 for the year, after many preseason polls had them ranked in the Top 5. Apparently, LSU had finally seen enough, after a year and a half of dry humping the idea of firing Miles. Defensive line coach Ed Orgeron will act as interim coach through the end of the season, as he did when Lane Kiffin was canned from USC.Miles took over after Nick Saban left LSU for the Dolphins in 2005. He won a national title in 2007, but despite wave after wave of elite NFL talent, failed to win another.His endearing quirks, like eating grass off the field, and steel spined 4th down calls, eventually gave way to fan and program frustrations with an offense that refused to evolve in the era of the spread, and could never find an elite quarterback. Advertisement Adapt, mutate, or die running an antiquated 1990’s high school offense at a major college football power. That’s from Charles Darwin or something.Colin is on record saying Bob Stoops would be a perfect fit to replace Miles. If it’s offense you want, it’s offense you’ll get. Houston’s Tom Herman may be the leader in the clubhouse.Here’s Colin’s full rant  on why Stoops to LSU makes sense.center_img “If Bob Stoops wants to be the best Bob Stoops, he should take that LSU job.” – @ColinCowherd #HerdHere pic.twitter.com/6PZ1MobY87— Herd w/Colin Cowherd (@TheHerd) September 17, 2016last_img read more
