Image: Katru Eco-Energy Citation: New omni-directional wind turbine can capture wind energy on building rooftops (2011, May 16) retrieved 18 August 2019 from https://phys.org/news/2011-05-omni-directional-turbine-capture-energy-rooftops.html More information: via New Inventors (video) Sureshan, who has been in the business of designing mechanical systems (such as the first hybrid rooftop solar air-conditioning unit to go up on a commercial building in Queensland, Australia), for over 25 years, says he began working on the design after spending a lot of time working on building rooftops and noting how there was a lot of very nearly constant wind flying around, and thought there ought to be a way to capture it and put it to good use.After studying then current ideas for capturing wind, Sureshan hit on the idea of building an enclosure of sorts, or shroud, with airfoil blades for “walls” that allowed air to travel inside the chamber, but because of the angle, would force it to flow upwards inside the chamber, rather than allow it to pass through and out the opposite side; all that wind (or at least 87% of it) would then flow upwards towards the horizontal blades connected to the turbine, which would spin, producing electricity. The result is a wind turbine that has just one moving part, is much quieter than most other turbines and doesn’t harm birds because they are too large to fit through the sidewall blades. It looks pretty cool as well. This document is subject to copyright.

It is considered to be a vertical wind generator, as its main rotor shaft is arranged vertically, and while it’s not the first to incorporate such technology it is unique in that it has horizontal blades, and because it’s likely the first to have been tested by Honda Formula 1’s racing team to validate its unique ability to capture wind and hold onto it, rather than letting any escape out the opposite side. © 2010 PhysOrg.com Smart wind turbines can predict the wind The Katru Eco-Energy website indicates the IMPLUX wind turbines should be ready for sale by mid 2012. (PhysOrg.com) — Katru Eco-Energy, headed by founder and inventor, Varan Sureshan, has developed a new kind of wind turbine meant to capture the winds that fly in all directions atop big buildings, and unlike conventional devices, the IMPLUX, as it’s called, can capture wind from any direction as it stands; meaning without having to be repositioned or pointed. The IMPLUX achieves this feat by means of horizontal turbine blades that sit atop a vertical axis and are turned by wind that is pushed up through what Sureshan calls a “fluid dynamic gate.”
Explore further Working principle of a thermoelectric generator. Credit: (c) Nature, VOL 508, 327 As the planet continues to experience the impact of global warming, scientists around the world frantically pursue alternate ways to produce electricity—one such possibility is to convert waste heat from industrial process into electricity. To make that happen, a thermoelectric generator must be constructed and used. Such generators operate by taking advantage of differences in temperature experienced by a single material. Two thermoelectric semiconductors are exposed to a temperature gradient and are connected together by conducting plates. Thus far, however, the process has not proved to be efficient enough to warrant the expense of building and using such generators, despite doubling in efficiency over just the past fifteen years—from zT 1 to 2.The increase in efficiency has been due mostly to research work involving nanotechnology, and the materials used have generally been based on lead telluride. The difficulty in finding better materials has been stymied by the dual properties required: low thermal conductivity and high electrical conduction. SnSe has been used by scientists for a variety of purposes, but due to its stiff bonds and distorted lattice was not really considered as a possibility. But that was because others had not taken into account the compound’s low anharmonicity. When the team at Northwestern tested it as a possible material for use in a thermoelectric generator they found it had the highest zT ever found, 2.6. © 2014 Phys.org More information: Ultralow thermal conductivity and high thermoelectric figure of merit in SnSe crystals, Nature 508, 373–377 (17 April 2014) DOI: 10.1038/nature13184AbstractThe thermoelectric effect enables direct and reversible conversion between thermal and electrical energy, and provides a viable route for power generation from waste heat. The efficiency of thermoelectric materials is dictated by the dimensionless figure of merit, ZT (where Z is the figure of merit and T is absolute temperature), which governs the Carnot efficiency for heat conversion. Enhancements above the generally high threshold value of 2.5 have important implications for commercial deployment1, 2, especially for compounds free of Pb and Te. Here we report an unprecedented ZT of 2.6 ± 0.3 at 923 K, realized in SnSe single crystals measured along the b axis of the room-temperature orthorhombic unit cell. This material also shows a high ZT of 2.3 ± 0.3 along the c axis but a significantly reduced ZT of 0.8 ± 0.2 along the a axis. We attribute the remarkably high ZT along the b axis to the intrinsically ultralow lattice thermal conductivity in SnSe. The layered structure of SnSe derives from a distorted rock-salt structure, and features anomalously high Grüneisen parameters, which reflect the anharmonic and anisotropic bonding. We attribute the exceptionally low lattice thermal conductivity (0.23 ± 0.03 W m−1 K−1 at 973 K) in SnSe to the anharmonicity. These findings highlight alternative strategies to nanostructuring for achieving high thermoelectric performance.Press release (Phys.org) —A team of researchers working at Northwestern University has found that tin selenide (SnSe) has the highest Carnot efficiency for a thermoelectric cycle ever found, making it potentially a possible material for use in generating electricity from waste heat. In their paper published in the journal Nature, the team describes work they’ve conducted on SnSe and how their discovery might lead to even more efficient materials. Joseph Heremans gives a short history of thermoelectric research in a News & Views companion piece and offers some insights into why SnSe might be so efficient and how it might lead the way to the discovery of even better materials. SnSe is the world’s least thermally conductive crystalline material. Heat cannot travel well through this material because of its very “soft”, accordion-like layered structure which does not transmit vibrations well. It reminds us of the TV commercial for posture-pedic mattress where one can jump up and down on one side of the mattress and a few feet away a glass of wine does not feel the vibrations. By analogy SnSe can get hot on one side and the other side remains cool. The cool side does not feel the vibrations (also known as phonons). In SnSe this means that all heat must go to the other side of the crystal “riding” on the electronic carriers, not lattice vibrations. Thus, the hot carriers can generate useful electricity during their transport. That is enabled by the high thermoelectric power of SnSe. The poor ability to carry heat through its lattice enables the resulting record high thermoelectric conversion efficiency. Credit: Lidong Zhao The increase in efficiency is clearly welcome, but is still not enough to revolutionize the field—what might would be the discovery of another material with an even higher efficiency—something that might be similar to SnSe.

Meanwhile, researchers at Arizona State University found that magnetic fields frozen into some meteorite grains were telling a shocking tale of the birth of the solar system. They suggest that shock waves moving through the material surrounding the early sun had a major impact on how the solar system was formed.

Infanticide has been documented in a variety of species, including lions, rodents, whales, and many types of primates, including humans. The general consensus in the scientific community is that the behavior occurs because it makes the mother more available to the male that does the killing. Less common is feticide, where a male causes harm to a pregnant female that results in the death of the fetus. In this new effort, the researchers report on the first-ever evidence of feticide in baboons.Prior research has shown that baboons engage in infanticide, but until now, it was not known that sometimes males also engage in feticide. In studying baboons in the Amboseli basin in Kenya the researchers report that they observed a number of feticide episodes by males that were new to a group. They note also that such attacks often left the mother dead as well, thus defeating the purpose of the attack. They report that causing a mother to abort a fetus reduced both pregnancy and lactation times, making the females more readily available for mating if they managed to survive the attack. They noted also that in cases when the female did survive, it was often the case that she would mate with her attacker.The researchers report that such attacks happened more often during periods of scarce resources; when new males managed to achieve high status quickly; when there were a lot of infants in a group; or if the males remained with a new group for more than three months. The team notes that it was obviously much more difficult to spot feticide than infanticide—they had to change their study habits to follow females after intercourse for a period of time to note changes in physiology or behavior that likely signaled a pregnancy and then to watch for episodes of violence against them and what followed afterwards. © 2017 Phys.org (Phys.org)—A team of researchers from several institutions in the U.S., some with ties to the Institute of Primate Research, National Museums of Kenya, has found that male baboons in the wild at times engage in feticide.

Zipple et al. Conditional fetal and infant killing by male baboons, Proceedings of the Royal Society B: Biological Sciences (2017). DOI: 10.1098/rspb.2016.2561AbstractSexually selected feticide—the death of infants in utero as a result of male behaviour—has only rarely been described or analysed, although it is presumed to be favoured by the same selective pressures that favour sexually selected infanticide. To test this hypothesis, we measured the frequency of feticide and infanticide by male baboons of the Amboseli basin in Kenya, and examined which characteristics of a male and his environment made him more likely to commit feticide and/or infanticide. We found a dramatic increase in fetal and infant death rates, but no increase in death rates of 1- to 2-year-old individuals, following the immigration of males who stood to benefit from feticide and infanticide. Specifically, fetal and infant death rates were highest following immigrations in which: (i) the immigrant male rapidly attained high rank, (ii) that male remained consistently resident in the group for at least three months, (iii) food availability and social group range overlap was relatively low and (iv) relatively many pregnant females and/or dependent infants were present. Together, these results provide strong evidence for the existence of both sexually selected feticide and infanticide in our population, and they indicate that feticide and infanticide are conditional male behavioural strategies employed under particular circumstances.Press release

(Phys.org)—Polycyclic aromatic hydrocarbons, such as graphene, have several potential uses as its π-conjugated structure lends itself to high stability and conductivity. Researchers are interested in exploring polycyclic aromatic hydrocarbons with boron and nitrogen atoms in an effort to explore the functionality and potential uses for polycyclic aromatic hydrocarbons. Journal information: Nature Chemistry Amino acids formed from the single-electron activation of carbon dioxide One polyatomic six-member ring that has not been isolated and studied is 1,3-dioxa-5-aza-2,4,6-triborinane, or DATB. DATB has a core B3NO2 ring that evidences some aromatic character. Hidetoshi Noda, Makoto Furutachi, Yasuko Asada, Masakatsu Shibasaki and Naoya Kumagai of the Institute of Microbial Chemistry in Tokyo (Bikaken) isolated and analyzed DATB using an m-terphenyl template. They demonstrated its ability to catalyze the direct coupling of several carboxylic acids with a variety of amines. Their DATB catalyst is thermally stable, structurally planar, and does not undergo hydrolysis. Their work appears in Nature Chemistry.The m-terphenyl template came out of the necessity to combine the B-N-B fragment to the O-B-O fragment to make the 1,2-dioxa-5-aza-2,4,6-triborinane ring. Using a stepwise synthesis, the first compound they made had the m-terphenyl template attached to the B-N-B portion of the DATB and a phenyl group attached to the boron of the O-B-O portion. The other compound that resulted from their initial syntheses had another m-terphenyl attached to the boron in the O-B-O portion of DATB instead of phenyl.The presence of DATB was confirmed with multinuclear NMR, mass spectrometry, and single-crystal x-ray diffraction. Notably, the DATB portion is planar and it exhibited offset face-to-face pi stacking. Additionally, it displayed slight aromaticity based on bond length and showed resistance toward hydrolytic cleavage.The next step was to determine if the DATB derivatives were able to catalyze amide bond formation. Boron has an affinity for amines, making this compound a possible option for catalyzing the direct coupling of amines and carboxylic acids. Noda et al. tested a variety of carboxylic acids because one of the major setbacks with amine and carboxylic acid coupling is that current methods are not generalizable for a variety of carboxylic acids, particularly bulky carboxylic acids. They tested a range of acids and amines whose coupling reactions were successfully catalyzed using DATB. They found that their DATB derivative successfully catalyzed the amide bond formation for sterically bulky aliphatic and aromatic carboxylic acids. They also found that indole-containing substrates did not require a protecting group. And, their method worked with benzoic acid and primary amines, α-branched amines, cyclic secondary amines. Using higher temperatures, they successfully coupled α-tertiary amines and acyclic secondary amines to benzoic acid. Additionally, they showed that the stereochemistry of α-chiral carboxylic acids and α-chiral amines were maintained.Their DATB derivative also worked well in the presence of various functional groups showing that the catalyst displayed good selectivity. Additionally, Noda et al. tested the catalyst’s ability to make peptide bonds with amino acids and biologically relevant amines by coupling Bz-Val-OH with H-Leu-NH2.This catalyst is remarkably versatile compared to other catalysts used for amine-carboxylic acid coupling. The authors contend that this is due to the distinct mechanism in which the three Lewis acid sites on the DATB core are used to bind the carboxylic acid and the amine countering the entropy cost in forming the bond.

Despite the rich chemistry of boron-containing heterocycles, the 1,3-dioxa-5-aza-2,4,6-triborinane (DATB) ring system, which is characterized by a six-membered B3NO2 core, remains elusive. Here, we report the synthesis of m-terphenyl-templated DATB derivatives, displaying high stability and peculiar Lewis acidity arising from the three suitably arranged boron atoms. We identify a particular utility for DATB in the dehydrative amidation of carboxylic acids and amines, a reaction of high academic and industrial importance. The three boron sites are proposed to engage in substrate assembly, lowering the entropic cost of the transition state, in contrast with the operative mechanism of previously reported catalysts and amide coupling reagents. The distinct mechanistic pathway dictated by the DATB core will advance not only such amidations, but also other reactions driven by multisite activation. Explore further © 2017 Phys.org

Explore further © 2017 Phys.org Three ‘super-Earth’ exoplanets orbiting nearby star discovered (Phys.org)—NASA’s prolonged Kepler exoplanet-hunting mission, known as K2, has revealed the presence of another “super-Earth” alien world. The newly found planet, designated EPIC 246393474 b (or C12_3474 b), is more than five times more massive than the Earth and orbits its parent star in less than seven hours. The discovery is reported November 6 in a paper published on the arXiv pre-print repository. Kepler is so far the most prolific planet-hunting telescope. The spacecraft has discovered more than 2,300 exoplanets to date. After the failure of its two reaction wheels in 2013, the mission was repurposed as K2 to perform high-precision photometry of selected fields in the ecliptic. Since then, the revived Kepler spacecraft has detected nearly 160 extrasolar worlds. Researchers have used K2 to detect so-called “super-Earths” – planets with masses higher than Earth’s but lower than that of the solar system’s gas giants. In September, astronomers have confirmed the discovery of three super-Earths orbiting a nearby star, which were first spotted by this spacecraft. Now, an international group of researchers led by Oscar Barragán of the University of Turin in Italyusing K2 has detected one more such planet.”In this paper we present the discovery of EPIC 246393474 b (hereafter C12_3474 b), an ultra-short-period planet transiting a K7 V star,” the astronomers wrote in the paper.The Kepler spacecraft observed a K-type main sequence star known as EPIC 246393474 from December 2016 to March 2017 during its Campaign 12. The star is about 740 million years old with a radius and mass approximately 33 percent smaller than that of the sun.As a result of these observations, the researchers identified a transit signal in the light curve of this star. The planetary nature of this signal was later confirmed by follow-up observational campaign using ground-based telescopes, including the WIYN 3.5-Meter Telescope at Kitt Peak National Observatory in Arizona.According to the study, EPIC 246393474 b has a radius of 1.54 Earth radii and is 5.3 times more massive than our planet, indicating a density of approximately 8.0 g/cm3 and suggesting a rocky-iron composition. The exoplanet has an equilibrium temperature of 2,039 K.”The planetary density is consistent with a composition made of a mixture of iron and rocks. We estimated that the iron content of C12_3474 b cannot exceed about 70 percent of the total planetary mass,” the paper reads.What is most interesting about EPIC 246393474 b is that it has an ultra-short orbital period. Barragán’s team found that it orbits its host every 6.7 hours at a distance of about 0.007 AU. This makes it the shortest-period planet known to date with a precisely determined mass.The researchers noted that the close distance of EPIC 246393474 b to its parent star suggests that it has lost its entire atmosphere due to stellar irradiation. However, they added that further mass measurements of transiting ultra-short-period planets should be performed in order to confirm this theory. More information: EPIC 246393474 b: A 5-M⊕ super-Earth transiting a K7 V star every 6.7 hours, arXiv:1711.02097 [astro-ph.EP] arxiv.org/abs/1711.02097AbstractWe report on the discovery of EPIC 246393474 b, an ultra-short-period super-Earth on a 6.7-hour orbit transiting an active K7 V star based on data from K2 campaign 12. We confirmed the planet’s existence and measured its mass with a series of follow-up observations: seeing-limited MuSCAT imaging, NESSI high-resolution speckle observations, and FIES and HARPS high-precision radial-velocity monitoring. EPIC 246393474 b has a mass of 5.31±0.46 M⊕ and radius of 1.54+0.10−0.09 R⊕, yielding a mean density of 8.00+1.83−1.45 gcm−3 and suggesting a rocky-iron composition.
