Zero-carbon electric transport is already in reach for small islands The HYmini is a handheld universal charger that captures wind power, solar power, and power from electrical outlets to charge a variety of portable devices. Explore further Although the charger, called HYmini, should be initially charged via an electrical wall outlet (which takes about 4 hours), it can be topped off away from home in windy or sunny conditions. With enough solar batteries, it’s possible to fully charge the HYmini without any electrical power. Wind power is intended solely for supplemental charging, though. When fully charged, HYmini’s 5V/1A lithium ion battery can provide power for cell phones, PDAs, MP3 players, iPods, and even digital cameras. Gadgets are hooked up to the charger via a USB cable and various adapters that are included in the package. miniWIZ claims the charger´s battery can be recharged up to 500 times, providing at least 1000mA/h of storage capacity that can be transferred to mobile devices. HYmini’s built-in wind charger consists of a micro wind power generator activated by a tiny fan. At wind speeds between 9 and 40 mph, the turbine can provide up to 1W of power with a 65 mA capacity. A green LED lights up when charging, which can also be used as a night light. The input current depends on the wind speed: in tests, 20 minutes of 19-mph winds could generate enough charge to power an MP3 player for 40 minutes, a cell phone for 4 minutes, or a digital camera for 20 pictures. The company suggests that the charger would be ideal when biking, skiing, or participating in similar high-speed activities, although it caps off at 40 mph for safety reasons. The charger is moisture-proof, and the turbine is made of soft PVC that breaks on impact to avoid injury. Replacement turbines can be purchased online.Besides electrical and wind, the HYmini can also be charged by the sun. The package comes with four optional 6-inch solar miniSOLAR panels, which can be linked together to the charger to provide up to 5V. When charging, a side indicator turns red to note that sunlight is being converted into electricity and stored in the device´s internal battery.The HYmini is available starting at USD $50 in black, white, and green. The miniSOLAR panels are $25 each, and the site also provides data on the average percentage of sunlight and wind speeds for various US cities.

“In simple words, the relation between quantum groups and noncommutative geometry is as follows,” he explained. “Classically, we know that certain spaces are invariant under the action of some classical groups; for example, Euclidean space is invariant under rotations and translations. A quantum group is a deformation of a given classical group, and is such that no classical space can have it as a symmetry group. The invariant space has to be as well a deformation of a classical space, a deformation that makes it noncommutative. No relation of all this to fractals is known, but in my work I’ve found that they do have a common property, that is, a non-integer dimension (at some scale).”Compared to a Euclidean sphere, a quantum sphere’s curvature and uncertainty make it a noncommutative space. When calculating the spectral dimension of the quantum sphere, Benedetti found that it closely resembles a standard sphere on large scales; however, as the scale decreases, the dimensions of the quantum sphere deviate and go down to zero. He describes this phenomenon as a signature of the fuzziness, or uncertainty, of the quantum sphere, and also as resulting from fractal behavior at small scales.In the second kind of space, k-Minkowski spacetime, the dimensions also deviate from the constant behavior of classical Minkowski spacetime. While the latter always has four dimensions, independent of the scale, the number of dimensions in the quantum version decreases to three as a function of the scale. In both k-Minkowski spacetime and the quantum sphere, the dimensionality becomes non-integral, which is a typical signature of fractal geometry.Benedetti’s results match previous approaches to quantum gravity, which also point to the emergence of a ground-scale spacetime with fractal properties. Together, these studies may help scientists understand the unique Planck scale properties of spacetime, and possibly tie in to a quantum theory of gravity. For instance, as Benedetti explains, the fractal nature of quantum spacetime might enable gravity to cure its own ultraviolet behavior by dimensional reduction. “The main problem with gravity is that apparently it cannot be quantized as other field theories; in jargon it is said to be non-renormalizable,” he said. “This problem is specific to four-dimensional spacetime. If spacetime had only two dimensions, then quantum gravity would be much simpler and treatable. The problem with a two-dimensional theory is that it is unphysical, as we see four dimensions at our scales. Things can be solved combining four and two dimensions at different scales. That is, if gravity itself provides a mechanism by which the dimension of spacetime depends on the scale at which we probe it (four at our and larger scales and two at very short scales), then we could have a physical theory (compatible with observations) that is free of quantum (short scale) troubles.”More information: Benedetti, Dario. “Fractal Properties of Quantum Spacetime.” Physical Review Letters 102, 111303 (2009).Copyright 2009 PhysOrg.com.

Citation: Spacetime May Have Fractal Properties on a Quantum Scale (2009, March 25) retrieved 18 August 2019 from https://phys.org/news/2009-03-spacetime-fractal-properties-quantum-scale.html As if extra dimensions weren’t strange enough, new research has probed an even more mind-bending possibility: that spacetime has dimensions that change depending on the scale, and the dimensions could have fractal properties on small scales. In a recent study, Dario Benedetti, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, has investigated two possible examples of spacetime with scale-dependent dimensions deviating from classical values at short scales. More than being just an interesting idea, this phenomenon might provide insight into a quantum theory of relativity, which also has been suggested to have scale-dependent dimensions. Benedetti’s study is published in a recent issue of Physical Review Letters.“It is an old idea in quantum gravity that at short scales spacetime might appear foamy, fuzzy, fractal or similar,” Benedetti told PhysOrg.com. “In my work, I suggest that quantum groups are a valid candidate for the description of such a quantum spacetime. Furthermore, computing the spectral dimension, I provide for the first time a link between quantum groups/noncommutative geometries and apparently unrelated approaches to quantum gravity, such as Causal Dynamical Triangulations and Exact Renormalization Group. And establishing links between different topics is often one of the best ways we have to understand such topics.”In his study, Benedetti explains that a spacetime with quantum group symmetry has in general a scale-dependent dimension. Unlike classical groups, which act on commutative spaces, quantum groups act on nocommutative spaces (e.g. where xy doesn’t equal yx), which emerges through their unique curvature and quantum uncertainty. Here, Benedetti considers two types of spacetime with quantum group symmetry – a quantum sphere and k-Minkowski spacetime – and calculates their dimensions. In both spaces, the dimensions have fractal properties at small scales, and only reach classical values at large scales. Generally Speaking: A Primer on General Relativity As scale decreases, the number of dimensions of k-Minkowski spacetime (red line), which is an example of a space with quantum group symmetry, decreases from four to three. In contrast, classical Minkowski spacetime (blue line) is four-dimensional on all scales. This finding suggests that quantum groups are a valid candidate for the description of a quantum spacetime, and may have connections with a theory of quantum gravity. Image credit: Dario Benedetti.

Explore further (PhysOrg.com) — Usually, we think of spacetime as being four-dimensional, with three dimensions of space and one dimension of time. However, this Euclidean perspective is just one of many possible multi-dimensional varieties of spacetime. For instance, string theory predicts the existence of extra dimensions – six, seven, even 20 or more. As physicists often explain, it’s impossible to visualize these extra dimensions; they exist primarily to satisfy mathematical equations.
(Phys.org) —Researchers at the University of California, Berkeley, have discovered that a nanocrystal moving through a nanotube due to an electric charge is able to pass through a portion of the nanotube that is smaller in diameter than the crystal, without melting or undergoing compression. In their paper published in the journal Physical Review Letters, the team describes how they observed an iron nanocrystal move through a narrow channel in a nanotube without its properties being changed in the process.

Scientists have known for some time that if metal crystals are inserted into a nanotube, then the crystals will move through the tube if an electric current is applied. The speed and direction of the crystals can be controlled by modifying the amount and direction of the current. However, that was always done with uniform width nanotubes. In this new effort, the researchers created a nanotube that had a diameter of 20 nm for most of its length—in its middle section however, they caused the nanotube to constrict to a diameter of just 5 nm. The assumption was that when an electric charge was applied to an iron nanocrystal introduced into the nanotube, it would be stopped-up by the constriction until either the crystal melted due to the heat of the current applied, or was squished as it was forced through the smaller space. Instead, the researchers found, by watching through an electron microscope, that the crystal was able to move through the constriction before either occurred, without undergoing any changes at all. Instead, it simply rearranged itself. They noted also that the crystal moved through the constriction at the same speed, regardless of its length, so long as the current remained stable.The researchers aren’t sure exactly how the crystal was able to move through the constriction, but theorize that atoms on the back side of the crystal structure somehow migrated, or diffused to the front—over and over again until the crystal had, in essence, re-formed itself on the other side of the blockage. The discovery of this phenomenon could lead to new ways to synthesize metal crystals or to increase their purity.

Rev. Lett. 110, 185901 (2013) prl.aps.org/abstract/PRL/v110/i18/e185901AbstractUnder the application of electrical currents, metal nanocrystals inside carbon nanotubes can be bodily transported. We examine experimentally and theoretically how an iron nanocrystal can pass through a constriction in the carbon nanotube with a smaller cross-sectional area than the nanocrystal itself. Remarkably, through in situ transmission electron imaging and diffraction, we find that, while passing through a constriction, the nanocrystal remains largely solid and crystalline and the carbon nanotube is unaffected. We account for this behavior by a pattern of iron atom motion and rearrangement on the surface of the nanocrystal. The nanocrystal motion can be described with a model whose parameters are nearly independent of the nanocrystal length, area, temperature, and electromigration force magnitude. We predict that metal nanocrystals can move through complex geometries and constrictions, with implications for both nanomechanics and tunable synthesis of metal nanoparticles.

(Phys.org)—Scientists have found that an intricately beautiful yet poorly understood type of crystal found in soap bubbles follows the same mathematical rules as a much better understood type of crystal called martensite. Due to its extreme hardness, martensite has been used since the Iron Age to make swords and horseshoes. The soap-bubble crystals, on the other hand, which are called smectic liquid crystals (where “smectic” is derived from the Greek word for “soap”), have turned out to be what the scientists describe as “the world’s weirdest martensite.” While all crystals are known for their highly ordered, aesthetically appealing structure, smectic liquid crystals stand out because their microstructure is particularly unusual. Full of beautiful patterns of ellipses and hyperbolas that bend, rotate, and curve around each other, the microstructure of smectic liquid crystals has fascinated researchers since they first turned their microscopes upon them over a century ago. Martensite microstructure, on the other hand, is characterized by a simpler striped pattern.Discovering the connection between the two seemingly different types of crystals required the meeting of two experts in these areas: Randall Kamien, a physicist at the University of Pennsylvania who studies smectic liquid crystals, and Cornell University physicist James Sethna, who specializes in martensites.In a new paper published in Physical Review Letters, Kamien, Sethna, and their coauthors have modified the mathematical theory of martensites so that it also explains the unusual features of smectic microstructure. It turns out that the rules that describe how all of the ellipses and hyperbolas fill 3D space in the smectic microstructure are very similar to the rules that describe the relatively simpler patterns in martensitic crystals.”I’m excited because a weird, anomalous scientific backwater with beautiful phenomena has now been fit into a standard framework,” Sethna told Phys.org. “The mathematically beautiful theory of martensites, which until now mostly predicted layered structures, now has an amazingly rich example, smectic liquid crystals.”The resulting new theory of smectic microstructure captures observations made as far back as 1922, when the French mineralogist Georges Friedel discovered that smectic layers bend in a very specific way, into so-called “cyclides of Dupin.” These layers of curved surfaces have centers of curvature that all lie along another single curve. As the curved surfaces somewhat resemble flower petals curving around the center of a flower, the cyclides of Dupin give the crystals a “flower texture.” All of this highly ordered curvature also enables the complex surfaces to pack together very tightly. (Left) Simulations of smectic liquid crystals and (right) experimental martensites, which have a characteristic striped pattern. Small images of smectic liquid crystals in the middle show close-ups of ellipses and hyperbolas, which form curved patterns known as cyclides of Dupin. The microstructure also exhibits Apollonian packing, where the small gaps between ellipses are filled with smaller and smaller ellipses. The concentric circles can be described by the same mathematics used to describe light cones in special relativity. Credit for smectic liquid crystals: Liarte, et al. ©2016 American Physical Society. Credit for martensites: Chu and James. Besides the connection between the two crystals, there is another mathematical connection in this work, which is that to special relativity. In smectic liquid crystals, the cyclides of Dupin form concentric circles of increasing size that form cones which look like the “light cones” in special relativity. Light cones represent the path of light as it broadens in all directions, like light emerging from a flashlight. Since the crystal and light models are geometrically identical, the same math used in special relativity, such as manipulating the shapes with Lorentz transformations, can be used to describe these crystals.”The links to Einstein’s relativity are both real and theoretically cool,” Sethna said.Although the new theory of smectic liquid crystals and martensites describes many characteristics of both crystals, questions still remain regarding some of the unique geometrical features, and the researchers hope to continue to investigate these tiny structures in future work.”We’re hoping to extend our tools to analyze experimental smectic microstructures,” Sethna said. “There are some new imaging methods that should allow the layer orientations to be understood in three dimensions, and we should be able to use our numerical methods to figure out how the cyclides of Dupin (each with an ellipse and a hyperbola) fit together to fill the volume, adapt to changing boundary conditions, and evolve as the smectic flows.” More information: Danilo B. Liarte, et al. “Weirdest Martensite: Smectic Liquid Crystal Microstructure and Weyl-Poincaré Invariance.” Physical Review Letters. DOI: 10.1103/PhysRevLett.116.147802 Another characteristic that results in tight packing in the smectic microstructure is called “Apollonian packing.” Since there are small gaps between the ellipses, these regions are filled with smaller ellipses, and the gaps between them are likewise filled with even smaller ellipses, all the way down to the molecular scale. Both the Apollonian packing and cyclides of Dupin occur for the same reason: they offer the most energetically favorable arrangement for this crystal.

(Phys.org)—A team of researchers from several institutions in Australia has developed a model that sheds light on the social factors involved in getting users to cooperate on water conservation efforts. In their paper published in the journal Nature Human Behavior, the group describes the factors they used to build their model and what it revealed. More information: Juan Carlos Castilla-Rho et al. Social tipping points in global groundwater management, Nature Human Behaviour (2017). DOI: 10.1038/s41562-017-0181-7AbstractGroundwater is critical to global food security, environmental flows, and millions of rural livelihoods in the face of climate change. Although a third of Earth’s largest groundwater basins are being depleted by irrigated agriculture, little is known about the conditions that lead resource users to comply with conservation policies. Here we developed an agent-based model of irrigated agriculture rooted in principles of cooperation and collective action and grounded on the World Values Survey Wave 6 (n = 90,350). Simulations of three major aquifer systems facing unsustainable demands reveal tipping points where social norms towards groundwater conservation shift abruptly with small changes in cultural values and monitoring and enforcement provisions. These tipping points are amplified by group size and best invoked by engaging a minority of rule followers. Overall, we present a powerful tool for evaluating the contingency of regulatory compliance upon cultural, socioeconomic, institutional and physical conditions, and its susceptibility to change beyond thresholds. Managing these thresholds may help to avoid unsustainable groundwater development, reduce enforcement costs, better account for cultural diversity in transboundary aquifer management and increase community resilience to changes in regional climate. Although we focus on groundwater, our methods and findings apply broadly to other resource management issues. Throughout history, humans have been pulling water from rivers, lakes and streams to drink and to grow crops. More recently, humans have found it possible to access underground sources and have tapped into those, as well. Historically, there has been enough water to suit needs, but most scientists agree that is about to change. Underground water reservoirs such as aquifers are being depleted, and will soon run dry if something does not change. In this new effort, the researchers looked at the social factors involved when people in areas where water is likely to become scarce are pressed to cooperate in water conservation efforts.To create their model, the researchers chose three real-world locations that are believed to be at risk: the Murray–Darling Basin in Australia, the Punjab on the India/Pakistani border and California’s Central Valley in the U.S. They analyzed historical and physical data from all three regions, along with information from sources describing measures previously taken to coax such water users to conserve water, such as the Sustainable Groundwater Management Act in California. The group also added factors that account for social norms using cultural theory (grid–group or plural rationality)—all to answer three basic questions. The first involved revealing the relationship between those seeking to monitor water usage and their enforcement abilities, and the degree to which farmers and other water consumers complied. The second sought to better understand how social norms are involved in resource conservation efforts; the third was to find out which of the three regions under study was most likely to succeed in their efforts.The model showed that punishing water abusers in cooperative cultures such as in the Punjab was reasonably effective, whereas in places like the U.S. and Australia, the best approach appeared to involve inserting cooperative role models into a region who could persuade others to adopt conservation efforts.

In this new effort, the researchers have isolated one of the proteins involved in transporting other proteins from the cytoplasm, where they are made, into a chloroplast. Chloroplasts have two membranes called TOC and TIC that proteins must pass through in order to do their work.In their effort, the researchers sought to find the answers to two major questions: How do protein complexes that are known to exist at the boundaries of the membranes help transport other proteins through the membranes? And how did the TOC/TIC system evolve?In taking a close look at chloroplasts, the researchers discovered that there was a previously unidentified protein located at the TIC—they named it TIC236. They found that TIC236 served as a link between the TOC and TIC. Normally, it is fixed to and interacts with the inner membrane, but part of it also extends into the area between the TIC and the TOC, where it interacts with another protein that does roughly the same job for the TOC, called TOC75. Thus, the two proteins serve as intermediaries.To answer their second question, the researchers suggest that their discovery of TIC236 adds credence to theories that propose that plants came into existence when a bacterium was consumed by a host cell, leading eventually to the development of chloroplasts. They offer a side-by-side comparison of a plant and bacterium cell, showing the similarities, which now includes TIC236.

A quartet of researchers from the University of Tokyo in Japan and the University of Reading in the U.K. has found an association between the evolution of foot posture and body size in mammals. In their paper published in Proceedings of the National Academy of Sciences, Tai Kubo, Manabu Sakamoto, Andrew Meade and Chris Venditti describe their study of foot posture in a large variety of extant mammal species and their subsequent development of a phylogenetic tree. Journal information: Proceedings of the National Academy of Sciences Explore further The researchers note that all modern mammals can be classified by one of three types of foot posture: flat-footed, tiptoed and hooved. Flat-footed creatures include species like humans and mice. Tiptoed species include animals such as dogs and cats and hooved species include creatures such as horses and deer. In this new effort, the researchers began by classifying 880 species of extant mammals by their respective foot-posture type. They note that most species were easy to classify, while some, such as elephants (flat-footed) and rhinos (tiptoed) were not.Once the team completed the classifications, they plotted the species under study on a family tree that included all mammalian species—they also added some extinct species with known foot types. They were able to see associations in the tree between species based on foot type. In so doing, they found that foot type could be generally associated with body size. Animals with hooves, for example, tended to be large. They also found that tiptoed animals were, on average, twice as big as flat-footed animals, though there were some notable exceptions. People are generally bigger than dogs and housecats, for example. They also found that hooved animals were actually a lot bigger on average than tiptoed animals—57 times as big. The researchers noted that the association between foot type and size posed the question of which came first—did the development of hooves allow certain species to grow bigger, or did hooves come about because larger animals needed them?The researchers also used their tree to analyze historical specimens and found evidence that suggested the first mammals to evolve likely belonged to the flat-footed category.
