Molten magnesium (blue) is the top electrode, in the middle is the electrolyte (green), and molten antimony (yellow) is the bottom electrode. Image credit: Arthur Mount. Recently, researchers from MIT have designed a new kind of battery that, unlike conventional batteries, is made of all-liquid active materials. Donald Sadoway, a materials chemistry professor at MIT, and his team have fabricated prototypes of the liquid battery, and have demonstrated that the materials can quickly absorb large amounts of electricity, as required for solar energy storage.”No one had been able to get their arms around the problem of energy storage on a massive scale for the power grid,” says Sadoway. “We’re literally looking at a battery capable of storing the grid.”The battery consists of three layers of liquids: two electrode liquids on the top and bottom (electrodes are usually solid in conventional batteries), and an electrolyte liquid in the middle. In the researchers’ first prototype, the electrodes were molten metals – magnesium on the top and antimony on the bottom – while the electrolyte was a molten salt such as sodium sulfide. In later prototypes, the researchers investigated using other materials for improved performance.Since each liquid has a different density, the liquids automatically form the three distinct layers. When charging, the solid container holding the liquids collects electrons from exterior solar panels or another power supply, and later, for discharging, the container carries the electrons away to the electrical grid to be used as electricity.As electrons flow into the battery cell, magnesium ions in the electrolyte gain electrons and form magnesium metal, rising to form the upper molten magnesium electrode. At the same time, antimony ions in the electrolyte lose electrons, and sink to form the lower molten antimony electrode. At this point, the battery is fully charged, since the battery has thick electrode layers and a small layer of electrolyte. To discharge the electrical current, the process is reversed, and the metal atoms become ions again. As Sadoway explained in a recent article in MIT’s Technology Review, the liquid battery is a promising candidate for solar energy storage for several reasons. For one thing, it costs less than a third of the cost of today’s batteries, since the materials are inexpensive and the design allows for simple manufacturing. Further, the liquid battery has a longer lifetime than conventional batteries, since there are no solid active materials to degrade. The liquid battery is also useful in a wide range of locations compared with other proposed solar storage methods, such as pumping water. Most importantly, the liquid battery’s electrodes can operate at electrical currents tens of times higher than any previous battery, making it capable of quickly absorbing large amounts of electricity.The researchers hope to commercialize the liquid battery in the next five years. As Sadoway explained, connecting the batteries into a giant battery pack to supply electricity for New York City would require nearly 60,000 square meters of land. Such a battery pack could store energy from enormous solar farms, which would replace today’s power plants and transmission lines as they become old.via: Technology Review© 2009 PhysOrg.com New superomniphobic glass soars high on butterfly wings using machine learning (PhysOrg.com) — One of the biggest challenges currently facing large-scale solar energy technology is finding an effective way to store the energy, which is essential for using the electricity at night or on cloudy days.

Prototype binoculars from NHK showstop CEATEC crowd

first_img(Phys.org)—NHK is drawing interest at this week’s CEATEC in Japan with its prototype 3-D binoculars. They take advantage of something called “8K” resolution so that the user can now zoom into an image without sacrificing image quality. 8K resolution means that you can zoom up to sixteen times and not have to make do with lower image quality. Ultra-high definition television now includes both 4K (2160p) and 8K (4320p) digital video formats. Broadcasts in 8K will offer a resolution sixteen times as sharp as current HD TVs with 2MP resolutions. NHK showed off the technology in London recently during the Olympics.The CEATEC binocular display, beyond TVs, allows NHK to demonstrate the benefits of 8K.which NHK also calls Super Hi-Vision. The binoculars showed 3-D diorama images of locales in Japan that were filmed with Super Hi-Vision cameras in 4K or 8K. The goggles have a lever for manipulation and by panning the viewer zooms in and out of the image. Suggested application could be as viewing tools for sightseeing spots and museums.

More information: J. Zheng et al. Universal dependence of hydrogen oxidation and evolution reaction activity of platinum-group metals on pH and hydrogen binding energy, Science Advances (2016). DOI: 10.1126/sciadv.1501602AbstractUnderstanding how pH affects the activity of hydrogen oxidation reaction (HOR) and hydrogen evolution reaction (HER) is key to developing active, stable, and affordable HOR/HER catalysts for hydroxide exchange membrane fuel cells and electrolyzers. A common linear correlation between hydrogen binding energy (HBE) and pH is observed for four supported platinum-group metal catalysts (Pt/C, Ir/C, Pd/C, and Rh/C) over a broad pH range (0 to 13), suggesting that the pH dependence of HBE is metal-independent. A universal correlation between exchange current density and HBE is also observed on the four metals, indicating that they may share the same elementary steps and rate-determining steps and that the HBE is the dominant descriptor for HOR/HER activities. The onset potential of CO stripping on the four metals decreases with pH, indicating a stronger OH adsorption, which provides evidence against the promoting effect of adsorbed OH on HOR/HER. © 2016 Phys.org In order to make a better catalyst for these fuel cells, Jie Zheng, Wenchao Sheng, Zhongbin Zhuang, Bingjun Xu, and Yushan Yan from the University of Delaware and Columbia University studied the factors that affect the hydrogen oxidation reaction (HOR) and the hydrogen evolution reaction (HER) in a hydroxide exchange fuel cell. Their previous studies showed that the dominant controlling factor in the HOR/HER reactions is hydrogen adsorption on the platinum electrode, i.e., hydrogen binding energy. In this study they determined that the hydrogen binding energy was directly related to electrolyte pH, not metal identity or the metal’s oxophilicity. Their work appears in Science Advances.Previous studies have shown that there is some correlation between the hydrogen oxidation reaction, hydrogen binding energy, and electrolyte pH. These factors seemed to be independent of the metal’s properties. In this study Zheng, et al. sought to better understand the effect of pH on hydrogen binding energy and how hydrogen binding energy affects the HOR/HER kinetics. They tested this by investigating current densities over a large pH range on carbon-supported platinum-metal nanoparticles (e.g., Pt, Ir, Pd, and Rh).Using cyclic voltammetry, Zheng, et al. determined desorption peak potentials for deposited hydrogen on each of the supported metal nanoparticles at various pH values. They observed a similar linear correlation for all of the metals in which higher pH lead to a positive shift. The results of this study indicate that there is a generalizable trend between hydrogen binding energy and electrolyte pH that is independent of the metal used.If pH affects hydrogen binding energy, then does it also affect the hydrogen oxidation and evolution reactions? In order to relate pH to HOR/HER activities, they used a rotating disk electrode and calculated exchange current density. They found that as pH increased, current density decreased, demonstrating that, indeed, higher hydrogen binding energy leads to lower HOR/HER activity.Armed with this data, Zheng, et al. then used mathematical manipulations to generalize the trends between exchange current density and hydrogen binding energy. From these they could calculate the activation energy of the hydrogen oxidation and evolution reactions in 0.1M KOH for all of the metal nanoparticles. Their results verify that the reaction’s high activation energy is due to hydrogen binding energy, and therefore, it is the dominant factor in HOR/HER kinetics in alkaline electrolytes.Finally, their last study looked at whether hydroxide ions played a role in the hydrogen oxidation reaction. Since hydrogen binding to the metal electrode is the key factor in HOR kinetics, Zheng, et al. wanted to determine whether adsorbed hydroxide ions also affected the kinetics. By looking at potentials where carbon monoxide is stripped from the electrode, they were able to deduce that hydroxide likely does not play a key role in HOR/HER activities.This research provides important insight into why the reaction kinetics is significantly slower in hydroxide exchange fuel cells. The pH apparently affects hydrogen binding energy, which directly affects HOR/HER kinetics. Of particular significance is that this trend holds regardless of the platinum-group metal used. Further research will look into ways to tailor hydrogen adsorption. Citation: Hydrogen oxidation and evolution reactions in fuel cells slow down because of hydrogen binding (2016, March 31) retrieved 18 August 2019 from https://phys.org/news/2016-03-hydrogen-oxidation-evolution-reactions-fuel.html Journal information: Science Advances (Phys.org)—As scientists look for alternative energy sources, fuel cells that operate in a basic environment have garnered much attention. Typically fuel cells require an expensive catalyst, such as platinum. Hydroxide exchange fuel cells involve the movement of hydroxide ions (OH-) across a polymer membrane. The alkaline environment is conducive to the oxidation and reduction reactions without the need for expensive metals. However, these reactions are quite slow requiring a better catalyst.last_img read more

Astronomers detect new massive stars in the young cluster VVV CL074

first_img Astronomers detect 130 short period variable stars © 2019 Science X Network Massive stars evolve into different types of objects depending on their initial mass. However, many aspects of this process remain unknown as the evolution of massive stars is still not fully constrained. One of the methods that could be helpful in resolving these uncertainties is the study of young, massive clusters hosting various populations of massive stars.So a group of astronomers led by Fabrice Martins of the University of Montpellier, France, performed observations of a massive young cluster known as VVV CL074. For this purpose, they used the Spectrograph for INtegral Field Observations in the Near Infrared (SINFONI) instrument on VLT.”In the present paper, we describe new spectroscopic observations of the young massive cluster VVV CL074. Using integral-field spectroscopy, we characterize the spectral properties of the brightest members and identify new OB and WR [Wolf-Rayet] stars,” the astronomers wrote in the paper.In general, the team has investigated the presence of hydrogen, helium, and sometimes carbon and nitrogen lines in the K-band spectra of 25 massive stars in VVV CL074. The results show that 19 of the studied objects are newly discovered stars. Fifteen of the newfound stars are most likely the members of the cluster, while the remaining four were classified as foreground stars.From the sample of the 25 studied objects, three of them were found to be WR stars, while the rest turned out to be O and B stars. Besides these stars, the astronomers additionally identified 21 objects with spectra exhibiting strong carbon monoxide absorption.According to the study, the distance to VVV CL074 was calculated to be about 33,000 light years, which makes it one of the farthest young massive clusters identified to date. The astronomers estimate that most of the stars in the sample are between 3 and 6 million years old. They also found that the initial mass of two WR stars (designated WN8 and WC9) was apparently between 40 and 60 solar masses.By comparing the results with properties of other similar clusters in the Milky Way galaxy, the researchers drew final conclusions that could improve our understanding of evolutionary pathways of massive stars.”The central cluster of the galaxy is older than VVV CL074. Its WR population comes from stars with lower initial masses compared to the progenitors of the WR stars in VVV CL074. WN8 and WC9 stars being present in both clusters, this shows that such spectral types are encountered during the evolution of stars with a range of initial masses,” the authors of the paper concluded. Using ESO’s Very Large Telescope (VLT), an international team of astronomers has investigated a population of massive stars in the young cluster VVV CL074. The observations resulted in disclosing fundamental properties of 25 stars, out of which 19 were identified for the first time. The findings were presented in a paper published July 4 on arXiv.org.

Playing the devils advocate

first_imgPerhaps the typical first question – why the pseudonym/pen-name? Why not just be co-authors?We like to keep our fiction separate from our non-fiction. We weren’t originally intending that anyone should know who Alex Rutherford is. Also, we understand that publishers prefer a single name on the cover but you’d better ask them. We’ve now got very used to ‘Alex’ who’s a real person to us.What inspired you to write Empire of the Moghul series? Our travels in India first sparked our interest in the Moghuls as well as the country’s other cultures and dynasties. We’ve spent over 18 months of our lives in India at different times. It inspired us, among many other things, to start reading the Moghul chronicles and then to write a non-fiction book on the Taj Mahal (under our real joint names!) before embarking on the Empire of the Moghul series. Also Read – ‘Playing Jojo was emotionally exhausting’Since it is history you are dealing with – whose side are you on? The victors as always or do you have some sympathy for the losers as well (in this case the rest of India that the Moghuls conquered)?It’s true that history favours the victor because that’s who generally writes the history. Victory often goes to the strong, not to the best or nicest people, so, of course, we have sympathy for those who do not win and have to live with consequences and still preserve their culture, which the Indian people did magnificently. Even within the Moghul hierarchy, there are winners and losers. We have great sympathy for Dara and Jahanara for example. Also Read – Leslie doing new comedy special with NetflixWho is your favourite Moghul and why? Gosh, that’s a hard one. We liked Babur for his determination to succeed in the face of all the odds and for writing such frank memoirs, even though Baburnama now only exists in parts. We also have huge admiration for Akbar for trying to make his empire inclusive of all peoples and all religions – something very rare for his time anywhere in the world, especially when different sects of the Christian religion (Protestants and Catholics) were killing each other in Europe and fighting cruel wars. Why write about the Moghuls and not go further back in time and write about the Guptas? Or Ashoka? (Alternately – would you ever write about another dynasty?) We are currently thinking of going back further – with the encouragement of Hachette India – perhaps to Ashoka, but first we still have one more Moghul book to write, about Aurangzeb.Does the fact that the dynasty had Islam as its religion give it a more global appeal than writing about a Hindu dynasty or one Hindu ruler with a glorious career?That wasn’t a factor in our choice. We chose the Moghul dynasty for its richly-textured story. We hope the books are about characters and universal themes, such as love and ambition.From a publisher’s point-of-view, how feasible is historical fiction? We think historical fiction is still very popular and we’re very grateful to people in India for reading our works and hopefully enjoying them. The question about how marketable historical fiction is really should be aimed at the publishers.Is it harder to write historical fiction than a mythological one?Never having tried to write a story based on mythology, so this is hard to answer. But perhaps historical fiction imposes more constraints, particularly where there are detailed chronicles and other sources to which the writer has to have access.In The Serpent’s Tooth, your sympathies tend to lie with Shah Jahan and not with Aurangzeb. Will the loyalties shift by the next book to Aurangzeb?Aurangzeb is a complex character who had problems in his personal life – imprisoning and fighting several of his children as well as killing some of his brothers. In his public life, he alienated by his actions the majority of his subjects. We will try to understand what in his character and early experiences led him to do these things. For example, in a letter he wrote that his father never loved him. Perhaps, there lies a clue.There have been problems with revisiting Mughal history, as there is a rise in Hindu nationalism at present in India. Does that bother you?We always try to be true to what happened. We try to look at people’s characters and hopefully to cause offence to no one. We want people to enjoy our books and not be offended by them.last_img read more

Bridge collapses in Kakdwip

first_imgKolkata: Following Posta and Siliguri, another under-construction bridge collapsed at Kakdwip in South 24-Parganas on Monday morning. However, no one was injured. A detailed investigation has already been ordered by Sundarban development minister Manturam Pakhira. According to locals, the bridge was sanctioned and work started approximately two years ago. It was being constructed to connect West Steamer Ghat and West Gangadharpur. On Monday at around 10 am, locals heard a loud noise. When they moved towards the source of the sound, they found that a large portion of the bridge had collapsed. Administrative wings of the Sub-Division and the District Magistrate were immediately informed. Police also reached the spot to secure the area. Later, government officials arrived and inspected the situation thoroughly. “Some children were playing nearby. But all of them are safe,” said a local resident. Some of the locals claimed that during the construction of the bridge, a crack was found. But following an inspection by the engineers, a green signal was given to continue with the construction work. According to the government officials, there might have been some fault in the girders. Sources informed that the agency which was given the contract, has been showcaused by the Sundarban development department. The Sundarban development minister also raised finger toward the construction agency. A high power committee has also been formed following the incident. Four contractors have been ordered to appear before government officials on Tuesday by Pakhira.last_img read more
