Citation: New hydrogen storage material could be added directly to fuel tanks (2011, January 31) retrieved 18 August 2019 from https://phys.org/news/2011-01-hydrogen-storage-material-added-fuel.html (PhysOrg.com) — If hydrogen is to ever play a role in powering vehicles on a large-scale, researchers must not only find a way to produce hydrogen, but also a safe method to store it. Currently, storing hydrogen requires either very low temperatures or very high pressures, both of which are expensive, require large amounts of energy, and involve safety risks. Now a new spin-out company from Rutherford Appleton Laboratory in the UK called Cella Energy Ltd. is developing an inexpensive, practical method to store hydrogen that could be added directly to conventional automobile engines. The method could lead to clean hydrogen fuels for vehicles that can be pumped like gasoline, fuel additives to lower emissions in vehicles with minimal modifications, and even batteries that allow laptops to last a week between charges, among other uses.

The new storage technique stems from research performed by Professor Stephen Bennington, Dr. Arthur Lovell, and others at Rutherford Appleton Laboratory, the University College London and the University of Oxford. The researchers developed a way to make tiny microfibers that are just 2-50 nm in diameter using low-cost automated processes called electrospinning and electrospraying. The microfibers can then be woven together to create a micro-porous polymer that resembles tissue paper, or a similar technique can be used to make micro-beads. The tiny pores in the polymer can encapsulate a variety of hydrides, which are chemical compounds that include hydrogen and other elements. When the hydrides are trapped inside the polymers, the hydrogen can be rapidly desorbed (released) at low pressures and ambient temperatures. According to Cella Energy, the micro-porous polymers can store as much hydrogen for a given weight as high-pressure tanks. The micro-beads, which also encapsulate hydrides, are especially interesting for vehicular applications. The micro-beads resemble a fine powder and could potentially be poured and pumped like a fluid into vehicles’ fuel tanks. The company explains that the encapsulated hydrogen could be safely used in either an internal combustion engine or fuel cell. Once the hydrogen is desorbed from a bead, the empty bead is stored in a separate lightweight plastic tank in the vehicle. When the vehicle needs to be refueled, the waste beads are removed from the vehicle and taken elsewhere to be rehydrided and recycled. Unlike hydrogen stored in high-pressure cylinders, new micro-beads could be refueled into vehicles just like vehicles today are refueled with gasoline. The company adds that the hydrogen storage materials are actually safer to handle than gasoline.According to the CEO of Cella Energy, Stephen Voller, the technology has the potential to provide a driving range of 300-400 miles between fueling. As for pricing, an article on Gizmag says that the storage materials could lead to synthetic fuel that costs just $1.50 per gallon, although it’s not clear where that price comes from.During the past year, the researchers at Cella Energy have been experimenting with ammonia borane as the hydride. When encapsulated, the accessible hydrogen content is 6% by weight. Although this percentage exceeds the DOE target of 4.5wt%, it is less than that of ammonia borane in its normal state. However, one of the advantages is that the hydrogen in the new polymer is desorbed an order of magnitude faster and at more convenient temperatures than ammonia borane in its normal state. The researchers noted that, while this will work for proof-of-concept work, it is too expensive to make for a commercial product and cannot be easily recycled. The company is currently looking into different hydrides that have slightly lower hydrogen contents, but that could be recycled many hundreds of times.At this point, Cella Energy has at least one investor, the chemical company Thomas Swan and Co. Cella Energy hopes to perform the first road tests next year, and, if they go well, could commercialize the product within the next five years. © 2010 PhysOrg.com Explore further Putting the fuel in fuel cells More information: www.cellaenergy.comvia: Gizmag (Left) Cella Energy CEO Stephen Voller and (right) micro-beads that make up the new hydrogen storage material.

Official word has not been given yet on when this car will be available to the public, what markets it will be made available to, or what the car will cost. It does not take a brain surgeon to figure out that the car will be available in China, but who knows what other markets the McCar will find its way into. (PhysOrg.com) — Geely, an automotive manufacturer that is based in China, has created a new vehicle called McCar. Aside from creating a lot of Batman movie comparisons and jokes, it truly is an amazing vehicle. The McCar, which is not named for a famous sandwich created by a fast food chain that uses a clown as it mascot, is a hybrid car that is paired with a scooter in the rear. While this combination is a bit unusual, it provides the maximum in driver flexibility. The McCar was recently shown off to the public at Auto Shanghai auto show this week. Toyota shows off its new iQ electric-car prototype The McCar electric version features a 12kWh battery, which has a range of roughly 93 miles. This car will no doubt be for mostly city driving, since it has a top speed of only 52mp. Recharge time on the McCar’s battery is roughly six hours, which puts it ahead of some larger electronic cars. The hybrid version features a 8kWh battery that can run roughly 31 miles on electric power and up to 373 miles on a combination of gasoline and battery life, with a top speed of 80mph, which makes it the choice for longer trips. The hybrid is also good for impatient chargers, since it takes only two hours to recharge. The cars scooter has a range of 18 miles and a top speed of 18 miles per hour. Like the hybrid vehicle the scooter takes two hours to charge. Since this part charges while you drive, you won’t really have to wait. Explore further © 2010 PhysOrg.com The McCar is an ultra compact, two-door model with four-seats. The folding scooter in the back is entirely electric and has three wheels. Storing a bike in a car is nothing new, what makes the McCar unique is the fact that it can actually generate electricity with the movement of the car. The electricity can then be used to charge the electric scooter while it is docked in the trunk of the car. So, how could car could be greener than this? Since the main vehicle gives drivers a choice of a gas-electric hybrid or fully electric car, it really can’t.

Journal information: Proceedings of the National Academy of Sciences (Phys.org) —Fifteenth and sixteenth century Chinese workers transported enormous stones to the Forbidden City by carrying them in sledges along roads of artificial ice, according to Jiang Li of the University of Science and Technology in Beijing and his colleagues. The researchers translated a document showing that in 1557, workers used this method to transport a 123-ton stone more than 70 kilometers. Li and his team say that dragging large stones over ice, rather than over dry ground, reduced the amount of friction created and the number of workers needed for the job. The study appears in the Proceedings of the National Academy of Sciences. Construction of China’s Forbidden City, in present-day Beijing, began in 1417. The home of China’s emperors for almost 500 years, The Forbidden City incorporates stones weighing more than 100 tons extracted from the Dashiwo quarry, 70 kilometers away. The heaviest of these is the Large Stone Carving, which weighs more than 300 tons.Previous researchers assumed that the Chinese used wheeled vehicles to move the stones. The Chinese were using wheeled vehicles for transport by around 1500 BC, and there are no images of workers dragging stones over dry ground. However, none of the wheeled vehicles built before 1596 could carry more than 95 tons. Although some books mention that workers used an artificial ice path to transport the Large Stone Carving, there are no detailed historical records of this event.Li and his colleagues translated a Chinese text written in 1618 that describes how workers brought a 123-ton stone to the Forbidden City in 1557, during a mid-winter renovation project. The workers placed the stone on a sledge, which they then dragged along an artificial ice path, created by pouring well water onto the ground and then allowing the water to freeze. They dug wells every half kilometer. By pouring water over ice that had already frozen, they created a liquid surface that decreased the friction between the sledge and the ice. The workers had time to move the sledge across the liquid film before it froze.The team calculated that it would have taken 1,537 men to drag the load over dry ground. Dragging a sledge over ice would have required 338 men. Lubricating the ice would have reduced the workforce to 46 men. An ice road also eliminated the need to lay out wooden planks to create a smooth surface.Architects of the reconstruction debated whether to use sledges or mule-driven wagons. They chose sledges because they were safer and more reliable than wagons, although sledges required more time, money and manpower.The research suggests that, at the time, Chinese engineers knew more about friction than Western engineers did. Workers likely slid massive stones, such as this 300-ton marble carving in front of the Hall of Supreme Harmony in the Forbidden City, Beijing, China, along artificial ice paths.

Although in China spoked wheels appeared ca. 1500 B.C., in the 15th and 16th centuries sliding sledges were still used in transporting huge stones to the Forbidden City in Beijing. We show that an ice lubrication technique of water-lubricated wood-on-ice sliding was used instead of the common ancient approaches, such as wood-on-wood sliding or the use of log rollers. The technique took full advantage of the natural properties of ice, such as sufficient hardness, flatness, and low friction with a water film. This ice-assisted movement is more efficient for such heavy-load and low-speed transportation necessary for the stones of the Forbidden City. The transportation of the huge stones provides an early example of ice lubrication and complements current studies of the high-speed regime relevant to competitive ice sports.

Journal information: Nature Citation: A new way to create macrolides—from scratch—may help in battle against bacterial resistance (2016, May 19) retrieved 18 August 2019 from https://phys.org/news/2016-05-macrolidesfrom-scratchmay-bacterial-resistance.html For many years, the go-to drugs of choice for treating a variety of bacterial infections has been macrolides, which are all drugs that have been created by altering a natural form of erythromycin—but in recent years, bacteria have become resistant to many of the drugs that have been developed. New ones have been slow in coming, due to the difficulty in finding new ways to alter the original bacteria which means R&D costs have been rising. This development has led to near-panic in the health community as it appears that if something does not change soon, the arsenal of weapons used to fight many infections will be vastly depleted. In this new effort, the researchers report that they have found a new way to create new variations of macrolides that does not require using native erythromycin as a source—instead, they create them from scratch. This development means that many more variants can be created at far lower cost, helping to keep ahead of bacterial resistance.To create new macrolides, the team reports, they used a method that allows for modular building, which they liken to the way cell phones are made—they start by building small-chemical blocks and then “weld” them together using a process that requires very few steps. They report also that the technique can be applied on a multigram scale, which means enough can be created at a time for use in experiments geared towards testing the results in killing bacteria.To date, the team has produced 300 macrolides using their technique, which include some that have had already been created using the original method. They report that some have already been tested to see how well they fight bacteria and have met with some initial success. They acknowledge that a lot more work needs to be done to find out if drugs produced using the method are truly effective in fighting bacterial infections and if so, if they will prove to be safe for use in humans.

A platform for the discovery of new macrolide antibiotics, Nature (2016). DOI: 10.1038/nature17967AbstractThe chemical modification of structurally complex fermentation products, a process known as semisynthesis, has been an important tool in the discovery and manufacture of antibiotics for the treatment of various infectious diseases. However, many of the therapeutics obtained in this way are no longer effective, because bacterial resistance to these compounds has developed. Here we present a practical, fully synthetic route to macrolide antibiotics by the convergent assembly of simple chemical building blocks, enabling the synthesis of diverse structures not accessible by traditional semisynthetic approaches. More than 300 new macrolide antibiotic candidates, as well as the clinical candidate solithromycin, have been synthesized using our convergent approach. Evaluation of these compounds against a panel of pathogenic bacteria revealed that the majority of these structures had antibiotic activity, some efficacious against strains resistant to macrolides in current use. The chemistry we describe here provides a platform for the discovery of new macrolide antibiotics and may also serve as the basis for their manufacture. © 2016 Phys.org Explore further Linking antibiotic to antibody found able to kill MRSA hiding in mice cells (Phys.org)—A team of researchers at Harvard University has found a way to create new macrolides—a class of drugs used to fight bacterial infections.

Unraveling biological networks (Phys.org)—A trio of math and computer scientists has developed a means for developing generalized frameworks that allow for clustering networks based on higher-order connectivity patterns. In their paper published in the journal Science, Austin Benson and Jure Leskovec with Stanford University and David Gleich with Purdue University outline their framework ideas and offer real life examples of ways their techniques can be applied to help understand complex networks in simpler ways. Nataša Pržulj and Noël Malod-Dognin with University College London offer an analysis of the work done by the trio in a Perspectives piece in the same journal issue. Journal information: Science Social network diagram. Credit: Daniel Tenerife/Wikipedia More information: A. R. Benson et al. Higher-order organization of complex networks, Science (2016). DOI: 10.1126/science.aad9029AbstractNetworks are a fundamental tool for understanding and modeling complex systems in physics, biology, neuroscience, engineering, and social science. Many networks are known to exhibit rich, lower-order connectivity patterns that can be captured at the level of individual nodes and edges. However, higher-order organization of complex networks—at the level of small network subgraphs—remains largely unknown. Here, we develop a generalized framework for clustering networks on the basis of higher-order connectivity patterns. This framework provides mathematical guarantees on the optimality of obtained clusters and scales to networks with billions of edges. The framework reveals higher-order organization in a number of networks, including information propagation units in neuronal networks and hub structure in transportation networks. Results show that networks exhibit rich higher-order organizational structures that are exposed by clustering based on higher-order connectivity patterns. As the authors note, it is not difficult to make out patterns in very small networks, a person trying to do so need only watch the system at work for a period of time. It is when networks become bigger and more complex that they become unwieldy. Even in such cases, however, low-order patterns are often still easy to discern—counting nodes or edges for example, offers some degree of network size, though doing so tells you very little about what the network does and how—that is where high-order organizational principles come into play. Unfortunately attempts to create a means for providing more information or detail about such systems has to date, not met with much success. In this new effort, the researchers describe a framework they have developed that offers some of the pattern recognition seen in smaller networks, with more complex networks.They start, Pržulj and Malod-Dognin note, with one of the more common higher-order structures known as small network subgraphs, which they refer to as network motifs—those that are statistically significant can be used as building blocks for the building of a mathematical framework, which is of course what the researchers have done. Relationship identification among the motifs was done by applying clustering algorithms. The result is a framework that highlights and/or identifies which of the motifs are the most critical when a network is in operation.The trio tested their framework technique by using it to analyze part of the neuronal network of a roundworm, and report that it revealed the particular cluster of 20 neurons responsible for performing actions such as standing and wiggling its head. They also gained insights into air traffic patterns by using it to perform an analysis of airports in the U.S. and Canada. They suggest such frameworks may be used in a wide variety of applications.

Panel c) illustrates the Doppler signal induced by planet d, and panel d) shows the residuals of the 3PKM. Credit: Trifonov et al., 2017. Gas giant planet HD 27894 b appears to have at least two massive companions, according to a new study published June 1 in a paper on arXiv.org. One of the newly discovered alien worlds is a Saturn-mass planet, while the other one is a cold exoworld several times more massive than Jupiter. Located about 138 light years away from the Earth, HD 27894 is a non-active solar-type star of spectral type K2V approximately 20 percent less massive than the sun. In 2005, HD 27894 b was detected using radial velocity measurements conducted with the use of the European Southern Observatory’s (ESO) High Accuracy Radial velocity Planet Searcher (HARPS) at the La Silla Observatory in Chile.Given that HD 27894 has a low declination, visual brightness of 9.36 mag and a slow rotation period of about 44 days, it is an excellent target for HARPS observations. So after the discovery of HD 27894 b, researchers monitored the star using this spectrograph during three observational campaigns in 2006, 2013 and 2016.Now, an international team of astronomers led by Trifon Trifonov of the Max Planck Institute for Astronomy in Germany has analyzed the available archival and new HARPS data in order to find additional planets in the HD 27894 system. The study detected the presence of two gas giant exoplanets, which received designations HD 27894 c and HD 27894 d.”In this paper, we present an updated orbital configuration for the HD 27894 system; according to our self-consistent N-body analysis of the RV data, the system is composed of three planets, the inner two likely in a 2:1 MMR (mean motion resonance),” the researchers wrote in the paper.According to the research, HD 27894 c has a mass of about 0.16 Jupiter masses, an orbital period of 36 days and is circling its host at a distance of 0.2 AU. HD 27894 d is much more massive, with a mass of approximately 5.4 Jupiter masses. The Jovian planet is also orbiting the star at a much larger distance than the other two worlds in the system. It takes HD 27894 d over 14 years to complete one full orbit, as it is located almost 5.5 AU from the host. Moreover, the researchers noted that their new findings show that this planetary system has a unique configuration.”The co-existence of a massive, distant, and moderately eccentric Jovian planet and a possibly resonant inner pair of massive planets makes the HD 27984 system truly unique,” the paper reads.The authors reveal that such a configuration provides important hints about the formation and evolution of this system. They assume that the inner pair of planets has probably been trapped in a 2:1 MMR by smooth migration capture, while the outer planet migrated to its current distant position before the circumstellar disk evaporated, thus halting the migration.”The planetary system around HD 27894 is important for probing planetary formation and evolution scenarios and illustrates the importance of further follow-up of radial velocity planet hosts,” the astronomers concluded.

Auroras on Earth occur when magnetic reconnections (magnetic fields colliding) cause solar flares on the sun. When it happens, plasma carrying a magnetic field is shot out into space, some of which makes its way to Earth. When it collides with our planet’s magnetic field, auroras occur. The same process has been observed on Venus, Mars, Jupiter, Saturn and Uranus.In this new effort, the researchers were studying data sent back from the Cassini spacecraft, which orbited Saturn for 13 years. They were looking specifically at data that would provide more information regarding magnetic reconnections on the planet—prior research had shown that they occur on the dayside of the magnetopause (the point where the planet’s magnetic field meets the solar wind). There was also evidence that they occur on the nightside of its magnetodisk, which is a plasma ring formed near the equator by water and other materials emitted from its moons. But prior research had also suggested that there would be no reconnections on the dayside of the planet’s magnetodisk because the solar winds made the ot too thick for them to occur. But the researchers found evidence of reconnections in the magnetodisk at noontime anyway. The researchers suggest this apparent anomaly is likely due to Saturn’s high spin rate (a day is just 10 hours). The high rate, they note, likely compresses the magnetodisk , making it thin enough for reconnections to occur. The team also suggests that the reconnections they measured appear to be strong enough to create auroras.The researchers suggest that their findings indicate that unknown auroras might be happening on other planets as well, but have been overlooked because planet spin speed was not factored into calculations. They further suggest that similar reconnections might also be behind some unexplained pulses seen from Jupiter. Journal information: Nature Astronomy More information: R. L. Guo et al. Rotationally driven magnetic reconnection in Saturn’s dayside, Nature Astronomy (2018). DOI: 10.1038/s41550-018-0461-9AbstractMagnetic reconnection is a key process that explosively accelerates charged particles, generating phenomena such as nebular flares, solar flares and stunning aurorae. In planetary magnetospheres, magnetic reconnection has often been identified on the dayside magnetopause and in the nightside magnetodisc, where thin-current-sheet conditions are conducive to reconnection. The dayside magnetodisc is usually considered thicker than the nightside due to the compression of solar wind, and is therefore not an ideal environment for reconnection. In contrast, a recent statistical study of magnetic flux circulation strongly suggests that magnetic reconnection must occur throughout Saturn’s dayside magnetosphere. Additionally, the source of energetic plasma can be present in the noon sector of giant planetary magnetospheres. However, so far, dayside magnetic reconnection has only been identified at the magnetopause. Here, we report direct evidence of near-noon reconnection within Saturn’s magnetodisc using measurements from the Cassini spacecraft. The measured energetic electrons and ions (ranging from tens to hundreds of keV) and the estimated energy flux of ~2.6 mW m–2 within the reconnection region are sufficient to power aurorae. We suggest that dayside magnetodisc reconnection can explain bursty phenomena in the dayside magnetospheres of giant planets, which can potentially advance our understanding of quasi-periodic injections of relativistic electrons6 and auroral pulsations.Press release: phys.org/wire-news/289642898/m … anetary-differe.html Hubble spots auroras on Uranus This document is subject to copyright.
