Beyond some threshold in irradiance, radiation pressure overcomes the Laplace pressure. The liquid fiber is thus stabilized by the guided light and its radius is determined by the balance between pressure of radiation and Laplace pressure. Thus not only the liquid fiber is stabilized by the light, but its radius self-adapts spontaneously to the beam intensity. “The radius and the length of induced fibers being respectively micrometric and millimetric, these results allow us to advance a microfluidic approach of self-adapted optical guiding while proposing an original answer to the stabilization of liquid columns, a problem studied for the first time by Rayleigh more than one hundred years ago.”In their demonstration, the researchers used a near-critical phase-separated liquid mixture. They focused an argon ion laser beam down into the cell containing the liquid mixture, which was kept above a critical temperature of 35ºC (95ºF) to achieve a low interfacial tension of the meniscus separating the two coexisting fluid phases. When the beam had a high enough power (at least hundreds of milliwatts), and was aimed directly at the interface from the fluid phase of the largest index of refraction, the interface became unstable and formed into a liquid column, stable and perfectly guiding the exciting beam. The physicists explained that the liquid optical fiber strongly depended on the beam power, among other things. For instance, by adjusting the beam diameter inside the liquid, the scientists showed how the liquid optical fiber would change its properties to avoid collapsing. For example, when the beam “waist” (the narrowest part of the beam) is large, the liquid column’s diameter becomes varied across its length. Having different diameter values at a single time makes the system “multistable.” By understanding the underlying mechanisms of liquid optical fiber stability, the scientists hope their work will lead to the development of reconfigurable light-guiding applications, microdevices with fluid interfaces, and other optofluidics technologies, since droplet microfluidics always involves low interfacial tensions between oil and water by adding surfactants.More information: Brasselet, Etienne; Wunenburger, Régis; and Delville, Jean-Pierre. “Liquid Optical Fibers with a Multistable Core Actuated by Light Radiation Pressure.” Physical Review Letters 101, 014501 (2008).Copyright 2008 PhysOrg.com.

Liquid columns reach a fundamental limitation called the Rayleigh-Plateau instability which says that, in weightless conditions, a liquid column breaks when its length exceeds its circumference. Now, a team of physicists, Etienne Brasselet, Régis Wunenburger, and Jean-Pierre Delville, from the University of Bordeaux in France, has developed a model to explain how a liquid column of large aspect ratio can be stabilized by light radiation pressure. The physicists demonstrated how the characteristics of a liquid optical fiber can be tuned at will, opening the doors to the further development of stable liquid optical fibers and their applications.In 2004, Delville was part of a team that discovered that light radiation pressure has the unique ability to stabilize liquid columns and overcome the Rayleigh-Plateau limit. Further, their technique enabled the liquid columns to self-adapt to the laser that was used to form them, self-tuning their diameter and adjusting their bending angle. However, no one knew the mechanism behind this stabilizing technique, until now. In a recent issue of Physical Review Letters, the University of Bordeaux physicists explain liquid column stability by a balance between the radiation pressure, which tends to expand a cylindrical column outwards, and the inward constricting interface stresses exerted by the Laplace pressure. Based on their model, the researchers could generate liquid optical fibers with aspect ratios of up to 100 (fibers whose lengths were 100 times greater than their diameters).“Strictly speaking, here is the main idea,” Delville told PhysOrg.com. “Squeeze a drop of water between the thumb and the index finger, and then move the two fingers away from each other. The drop takes the form of a small liquid fiber. Stretch still a little more and this fiber breaks in two daughter drops under the influence of surface stresses in order to minimize the energy associated with the increase in water-air surface due to stretching. That is why liquid fibers are so difficult to stabilize.

Do laser printers emit harmful particles? Citation: Scientists Make Ink Disappear, Make Paper Reusable (2009, October 27) retrieved 18 August 2019 from https://phys.org/news/2009-10-scientists-ink-paper-reusable.html (PhysOrg.com) — Despite ongoing efforts to save the trees, many offices print high volumes of paper documents on a daily basis. Although many companies encourage paper recycling, both disposing of and recycling paper have negative environmental impacts. What if there was a way to reuse printed paper by removing the ink and quickly transforming it back into clean, white paper? That’s the idea from Thomas Counsell and Julian Allwood of the University of Cambridge, who have investigated print removal techniques in a recent study. Of course, as Counsell and Allwood note, the idea is not new. Since medieval times, monks have removed the print from parchment to allow it to be reused, and a handful of patents already exist on the concept, though the techniques used are unclear.In 2006, Counsell and Allwood outlined a program of research into toner removal, and their most recent study, published in the Proceedings of the Royal Society A, demonstrates a promising toner removal method. They found that a combination of solvents can remove toner print from paper without harming the paper to make it reusable, although the resulting paper is not quite as white as new paper.In experiments, the researchers used a single toner-paper combination: the toner came from an HP 4200 dtn black-and-white laser printer, while the paper was white, uncoated, wood-free 80 gm-2 Canon copy paper. Upon experimenting with several solvents and combinations, the researchers found that applying a mixture of 60% dimethylsulphoxide and 40% chloroform, followed by an application of ultrasound agitation to separate the pigment from the paper, could make the paper sufficiently reusable. As the researchers found, dimethylsulphoxide alone is poor at removing print but results in white paper, while chloroform is better at removing print but leaves a grey surface. Together, the solvents provide a paper that has a slightly off-white color and a slightly rougher surface than a new sheet of paper, but is still re-printable. The scientists suggest that, in the future, a technique for removing print from paper might be carried out at a central recycling plant or in an office, such as by being integrated into a copy machine, printer, or recycling bin. But while solvents like chloroform would probably be acceptable to use at a plant, some solvents would probably not be considered safe for office use. Before the researchers start considering implementing the technique, more work is needed, particularly in investigating the economic, safety, and environmental implications. For one thing, the researchers want to perform repeated tests on the paper over multiple cycles of reuse and over extended periods, in order to determine the lifespan of the paper. In addition, other paper types and printer types would likely work better with different solvents.In addition to paper lifetime, there are sustainability issues to consider as well. For instance, in the experiments, at least 100 ml of solvent was required to clean a sheet of paper that had been covered with the standard 5% coverage of print that is quoted by printer manufacturers. At 10 sheets of paper cleaned per liter of solvent, the process raises questions about viability and the possibility of reusing the solvent, which would likely have further safety and economic issues. Despite these challenges, the basic principle of removing toner print from paper with solvents appears plausible, and may have benefits if investigated further.More information: Thomas A. M.

Leidenfrost wheels, Nature Physics (2018). DOI: 10.1038/s41567-018-0275-9AbstractAs reported in 1756 by Johann Gottlob Leidenfrost, volatile liquids on hot solids form “gleaming drops resembling quicksilver”, a consequence of their levitation on a vapour cushion. This makes the drops spectacularly mobile, moving away as soon as they are deposited—an observation commonly attributed to gravity or surrounding airflows. This mobility has been exploited to manipulate drops, because tiny forces such as those generated on asymmetric substrates can move them in well-defined directions, a situation that also provides heat evacuation. Here we report that Leidenfrost droplets initially at rest on horizontal substrates self-rotate and self-propel in the direction they are rolling, in the absence of any source of asymmetry or external force. Their rapid internal flow is found to be accompanied by a tilting of their base, which creates a permanent ratchet-like mechanism, entraining the rolling liquid despite the fact that it is not in contact with its substrate.

A water drop with radius R = 1.10 mm is dispensed from a needle at the centre of a hot wafer (T = 350 °C). Tracers (predispersed in the liquid) reveal an internal rolling motion before and after the drop detaches from the needle and self-propels in the rolling direction, like a liquid wheel. Credit: Nature Physics (2018). DOI: 10.1038/s41567-018-0275-9 The researchers also found that the unbalance inside the drop caused the drop to tilt downwards in the same direction that the drop was moving—sort of like a miniature tidal wave. That tilt, they note, worked like a ratchet to keep the drop moving until the drop evaporated completely. They also noted that the drops tended to roll towards a cooler part of the heated surface, suggesting that their movement might be controllable. If so, that could lead to a new type of self-propelled devices.

Droplet friction found to be similar to that of solid objects When drops of water land on a hot surface they begin moving around in the pan like a hockey puck on ice. Prior research has shown the slipperiness of the drops is due to a thin layer of steam that is created between the drop and the pan—causing the drop to be levitated. As to why the drop moves without prompting, prior researchers have suggested it is due to slight bits of air movement or gravity acting on them. In this new effort, the researchers have found that there is another force involved.To find out why the drops move without apparent cause, the researchers set up an experiment that involved placing a pan on a hot plate surrounded by high-speed cameras which were attached to motion-tracking software. To find out what goes on inside of the droplets, the group injected tiny glass spheres into a small sample of water which was used for generating droplets.In examining the results on their computer screen, the researchers found that larger drops behaved as expected—the glass spheres flowed in a smooth manner and the drops on the hot plate hardly moved. But as the drops on the pan grew smaller due to evaporation, they flattened out and the flow inside of the drops became unbalanced—the unbalance caused the drop to move forward.

Kolkata: In a sensational incident, a 45-year-old leather engineer who is a resident of Behala’s James Long Sarani, preserved the body of his mother inside a commercial chest freezer at his house for nearly three years after dissecting her body.The accused, Subhabrata Majumdar (45), has already been arrested. According to the preliminary investigation, police suspect that the accused used to withdraw his mother’s pension of Rs 50,000 per month by obtaining the thumb impression of the deceased. Also Read – Heavy rain hits traffic, flightsThe deceased, Bina Majumdar, was a retired employee of the Food Corporation of India (FCI). Her husband and the accused’s father, Gopal Majumdar, who also worked with the FCI, was probably threatened with dire consequences if he revealed the incident.Police said the accused worked in a leather company and had detailed knowledge about how chemicals could be applied for preservation of a dead body. What appears to be more shocking to the cops is that the accused dissected the deceased’s body from throat to lower abdomen to remove various organs which could trigger a foul smell in the neighbourhood. The incident came to light after the police, on specific information, raided the house on Wednesday night. Police are also investigating the role of the victim’s husband as to why he kept mum for almost three years despite knowing everything. It aroused the suspicion of the local residents who found that two air-conditioning machines were recently installed at the ground floor where the freezer was kept. Their suspicions rose as no one stayed on the ground floor and the machines used to run all the time. It was also learnt that the accused who did not mix with the neighbours for the past couple of years told some of them that he had kept his mother in the peace heaven.

Instead of cremating the body it was kept in a chest freezer and the accused son used to administer various chemicals to preserve the body. Police are also interrogating the hospital officials in this connection. Preliminary investigation suggests that the accused used to blackmail his father by saying if he makes the incident public then the accused would leave the house. The elderly father might not have revealed the incident due to his constant threats. He also concealed the death certificate inside the house. He used to withdraw the pension with the help of fudged documents. Police also found ink marks on the deceased’s thumb. The investigators seized various chemicals from the house. During interrogation, the accused has told the police that he could not bear the shock of his mother’s death as he was very close to her. He also told the police that he believes that human cells do not die. The accused further clarified that keeping the cells alive meant keeping the dead person alive. This was the reason behind preserving the body, he claimed.Police are also investigating as to why the accused, who used to work as a senior official at a leather company, had preserved the body of his mother inside a freezer for three years. He might have committed the crime to get his mother’s pension, police suspect. The accused used various foreign languages during the course of interrogation. Cops are also probing if he had any mental ailment. However, cops are investigating all possible angles behind the incident, including interrogation of the victim’s husband.

The beauty of Sufism lies in the translation of poetry into music, which not only makes up for an enriching experience for the listeners but also let them embark on a journey of soul-searching. Nizami Bandhu has a 700-year old rich legacy which they have upheld through centuries of dedication and tireless striving to perfection. They embraced Qawaali seven centuries back and since then, have contributed to the growth of this soulful genre of Sufism. The responsibility of carrying the legacy forward is presently being shouldered by Ustad Chand Nizami, Shadab Faridi Nizami, and Sohrab Faridi Nizami i.e., the Nizami Brothers. In a free-wheeling conversation with Puja Banerjee, the artists talk about the evolution of Sufi music, their views on remix culture and a lot more. Also Read – Add new books to your shelf How has the Sufi music evolved through the years?Sufi music has a long and golden history of more than 700 years. We have carried the legacy, which was handed over to us by Late Ghulam Farid Nizami. It has always been our responsibility to maintain the authenticity of Sufi music while we try to sync it with modern demands. Earlier, the sole objective of Sufi music was to spread the message of love, faith, and happiness. It was used to inspire people to do good deeds, however, with the passage of time, the music got transformed, and now we have the commercial version of it. Originally Sufi music was performed in shrines of dargahs, but now it is performed for the people across the globe. Also Read – Over 2 hours screen time daily will make your kids impulsiveWhy do you think Sufi music is popular in Hindi movies?Sufi music has a different beat and appeal. It transcends you into a different world. Moreover, we also feel that any new work is always appreciated by people, especially when it comes to music. Sufi music has added a new flavour to the traditional forms of music that we have, and this is the reason why Sufi music has been able to carve a discernible niche for itself in the film industry. Your views on fusion music and remixes? Music is the reflection of our culture, thinking, and beliefs. Any kind of change is indispensable, but it should be for the betterment. The way music is nowadays mixed and presented to people hampers the originality of the song and its essence. We are not against remixes or fusion music, but it should keep the real meaning of the song alive. Apart from this, what concerns us the most is the kind of lyrics we have in today’s songs, they are demeaning and sometimes derogatory. Many singers now use offensive language which unfortunately gets propagated to millions of people. As creative people, it’s our responsibility to spread the message of goodness. Your opinions on the reigning government banning Pakistani artists in India, which is the land of Sufi music?Well, if the government has decided to stop them, we abide by their decision. But at the same time, we would like to mention that music and creativity have no boundaries. Although there has been a taboo on the work of Pakistani artists in India, we cannot stop their creativity reach our land. We would like to keep politics and creativity separate.
