Australia: Scientists at the University of New South Wales  develop promising new approach to hydrogen storage.

Scientists at the University of New South Wales (UNSW), Australia, are developing a novel way to store hydrogen that could help turn it into a viable portable fuel source. The research centers on using synthesized nanoparticles of the compound sodium borohydride (NaBH₄ for those who love chemistry), which when encased inside nickel shells exhibits surprising and practical storage properties including the ability to reabsorb hydrogen and release it at much lower temperatures than previously observed, making it an attractive proposition for transport applications.

Hydrogen is a clean burning fuel that can be extracted from sources including natural gas, biomass, coal and water. One of the major problems in making it a viable alternative fuel is storage – the atoms are so tiny that they can easily escape from many kinds of containers. Also, hydrogen is more volatile than petrol. It can burn like blazes and can react badly to other substances. As no one wants to have a car that can burst into flames when you switch on the engine, this problem has drawn the attention of scientists around the world. When researchers from the UNSW Materials Energy Research Laboratory synthesized nanoparticles of the sodium borohydride and encased these inside nickel shells, the findings took them by surprise. Borohydrides (including lithium and sodium compounds) are known to be effective storage materials, but it was believed that once the energy was released it could not be reabsorbed. As a result, there has been little focus on sodium borohydride.

The new findings indicate that by controlling the size and architecture of these structures, their properties can be made reversible. In other words, NaBH4 absorbs the hydrogen like a sponge and then releases it, making it useful for application in vehicles. In its bulk form, sodium borohydride requires temperatures above 550°C just to release hydrogen. It’s pretty much the same even on the nano-scale, but this core-shell nanostructure saw energy release happening at just 50°C, and significant release at 350°C.

Dr Kondo-Francois Aguey-Zinsou from the School of Chemical Engineering at UNSW says this is a real breakthrough and his team hopes to have it commercialized in three to five years’ time. “No one has ever tried to synthesize these particles at the nanoscale because they thought it was too difficult, and couldn’t be done," he said. "We’re the first to do so, and demonstrate that energy in the form of hydrogen can be stored with sodium borohydride at practical temperatures and pressures.’’

The findings are published in the Journal ACS Nano.

Nano-structures to realise hydrogen’s energy potential

For the first time, engineers at the University of New South Wales have demonstrated that hydrogen can be released and reabsorbed from a promising storage material, overcoming a major hurdle to its use as an alternative fuel source.

 

Researchers from the Materials Energy Research Laboratory in nanoscale (MERLin) at UNSW have synthesised nanoparticles of a commonly overlooked chemical compound called sodium borohydride and encased these inside nickel shells.

 

Their unique "core-shell" nanostructure has demonstrated remarkable hydrogen storage properties, including the release of energy at much lower temperatures than previously observed. 

 

“No one has ever tried to synthesise these particles at the nanoscale because they thought it was too difficult, and couldn’t be done. We’re the first to do so, and demonstrate that energy in the form of hydrogen can be stored with sodium borohydride at practical temperatures and pressures,” says Dr Kondo-Francois Aguey-Zinsou from the School of Chemical Engineering at UNSW.

 

Considered a major a fuel of the future, hydrogen could be used to power buildings, portable electronics and vehicles – but this application hinges on practical storage technology.

 

Lightweight compounds known as borohydrides (including lithium and sodium compounds) are known to be effective storage materials but it was believed that once the energy was released it could not be reabsorbed – a critical limitation. This perceived “irreversibility” means there has been little focus on sodium borohydride.

 

However, the result, published last week in the journal ACS Nano, demonstrates for the first time that reversibility is indeed possible using a borohydride material by itself and could herald significant advances in the design of novel hydrogen storage materials.

 

“By controlling the size and architecture of these structures we can tune theirproperties and make them reversible – this means they can release and reabsorb hydrogen,” says Aguey-Zinsou, lead author on the paper. “We now have a way to tap into all these borohydride materials, which are particularly exciting for application on vehicles because of their highhydrogen storage capacity.”

 

The researchers observed remarkable improvements in the thermodynamic and kinetic properties of their material. This means the chemical reactions needed to absorb and release hydrogen occurred faster than previously studied materials, and at significantly reduced temperatures – making possible application far more practical.

 

In its bulk form, sodium borohydride requires temperatures above 550 degrees Celsius just to release hydrogen. Even on the nano-scale the improvements were minimal. However, with their core-shell nanostructure, the researchers saw initial energy release happening at just 50 °C, and significant release at 350 °C.

 

“The new materials that could be generated by this exciting strategy could provide practical solutions to meet many of the energy targets set by the US Department of Energy,” says Aguey-Zinsou. “The key thing here is that we’ve opened the doorway.”

Stanford scientists build the first all-carbon solar cell.

Stanford scientists build the first all-carbon solar cell.

Researchers have developed a solar cell made entirely of carbon, an inexpensive substitute for the pricey materials used in conventional solar panels.

Stanford Professor Zhenan Bao and her colleagues have developed the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today. Unlike rigid silicon solar panels that adorn many rooftops, Stanford's thin film prototype is made of carbon materials that can be coated from solution - a technique that has the potential to reduce manufacturing costs.

The Bao group's all-carbon solar cell consists of a photoactive layer, which absorbs sunlight, sandwiched between two electrodes.

Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today. The results are published in today's online edition of the journal ACS Nano.

"Carbon has the potential to deliver high performance at a low cost," said study senior author Zhenan Bao, a professor of chemical engineering at Stanford.  "To the best of our knowledge, this is the first demonstration of a working solar cell that has all of the components made of carbon. This study builds on previous work done in our lab."

Unlike rigid silicon solar panels that adorn many rooftops, Stanford's thin film prototype is made of carbon materials that can be coated from solution. "Perhaps in the future we can look at alternative markets where flexible carbon solar cells are coated on the surface of buildings, on windows or on cars to generate electricity," Bao said.

The coating technique also has the potential to reduce manufacturing costs, said Stanford graduate student Michael Vosgueritchian, co-lead author of the study with postdoctoral researcher Marc Ramuz.
"Processing silicon-based solar cells requires a lot of steps," Vosgueritchian explained. "But our entire device can be built using simple coating methods that don't require expensive tools and machines."

Carbon nanomaterials

The Bao group's experimental solar cell consists of a photoactive layer, which absorbs sunlight, sandwiched between two electrodes.  In a typical thin film solar cell, the electrodes are made of conductive metals and indium tin oxide (ITO). "Materials like indium are scarce and becoming more expensive as the demand for solar cells, touchscreen panels and other electronic devices grows," Bao said.  "Carbon, on the other hand, is low cost and Earth-abundant."


For the study, Bao and her colleagues replaced the silver and ITO used in conventional electrodes with graphene – sheets of carbon that are one atom thick –and single-walled carbon nanotubes that are 10,000 times narrower than a human hair. "Carbon nanotubes have extraordinary electrical conductivity and light-absorption properties," Bao said.  

For the active layer, the scientists used material made of carbon nanotubes and "buckyballs" – soccer ball-shaped carbon molecules just one nanometer in diameter.  The research team recently filed a patent for the entire device.

"Every component in our solar cell, from top to bottom, is made of carbon materials," Vosgueritchian said. "Other groups have reported making all-carbon solar cells, but they were referring to just the active layer in the middle, not the electrodes."

One drawback of the all-carbon prototype is that it primarily absorbs near-infrared wavelengths of light, contributing to a laboratory efficiency of less than 1 percent – much lower than commercially available solar cells.  "We clearly have a long way to go on efficiency," Bao said.  "But with better materials and better processing techniques, we expect that the efficiency will go up quite dramatically."

Improving efficiency

The Stanford team is looking at a variety of ways to improve efficiency. "Roughness can short-circuit the device and make it hard to collect the current," Bao said. "We have to figure out how to make each layer very smooth by stacking the nanomaterials really well."

The researchers are also experimenting with carbon nanomaterials that can absorb more light in a broader range of wavelengths, including the visible spectrum.

"Materials made of carbon are very robust," Bao said. "They remain stable in air temperatures of nearly 1,100 degrees Fahrenheit."

The ability of carbon solar cells to out-perform conventional devices under extreme conditions could overcome the need for greater efficiency, according to Vosgueritchian. "We believe that all-carbon solar cells could be used in extreme environments, such as at high temperatures or at high physical stress," he said. "But obviously we want the highest efficiency possible and are working on ways to improve our device."

"Photovoltaics will definitely be a very important source of power that we will tap into in the future," Bao said. "We have a lot of available sunlight. We've got to figure out some way to use this natural resource that is given to us."

Other authors of the study are Peng Wei of Stanford and Chenggong Wang and Yongli Gao of the University of Rochester Department of Physics and Astronomy. The research was funded by the Global Climate and Energy Project at Stanford and the Air Force Office for Scientific Research.

Science: Revive a mammoth is possible.

This is not science fiction. The cloning of an animal it is possible and, oddly controversial, revive a mammoth species extinct for 4500 years is considered a scientifically viable project.

The investigator and veterinarian Hwang Woo-suk, stem cell specialist, leads the initiative.

Through an agreement with the Federal University Northeastern Russia, South Korean scientists Sooamd Research Foundation will attempt to clone a woolly mammoth through their tissue samples with eggs from a current Indian elephant.

After applying the cell nuclear transfer process, common step in the process of cloning, the egg is implanted in the uterus of a live elephant, the mammoth  gestates for 22 months.

The agreement with the Russian university comes six months after the two sides signed an initial pact for South Korean researchers could use the samples taken from mammoth remains found in the glaciers of the Sakha Republic in the Russian Federation. Hwang Woo-suk was once considered a pioneer in the field of stem cells to clone a dog in 2005.

Experts believe that it is possible to clone a mammoth, since prehistoric animal cells that can be found both in the blood and internal organs such as the skin and bones. A César Paz y Mino, academic and geneticist, not surprised with this possibility. "The mammoth cloning is possible because the animal is found male and female Indian elephant is. The egg is always more important than sperm. "

Although for Eugenia del Pino, director of the Laboratory of Developmental Biology at the Catholic University of Quito,Ecuador this type of cloning has already been made with live animals, the mammoth and the elephant, even if they have close relationship, are different species.

 Paz y Mino holds that in any case, after cloning animals will try to play to achieve purification of information. However, from a hybrid gene never achieve a 100% pure. What is the desire to clone a mammoth? "There's always the hope of resurrecting an extinct species," said Del Pino, who in his role as biologist would see again the kind of Lonesome George, of the Pinta Island.

She is aware that science has advanced, but the project certainly stem cell specialist because previous attempts have falsified evidence to confirm their novel theories about human cloning.

 In 2009, a Seoul court sentenced him to two years in prison for falsification of genetic data and use public funds for their scientific projects. Additionally, the hypothetical cloning could affect the environment. "It is best to protect our planet, with its plant and animal species. You have to let the mammoths as beings of the past, "adds the researcher. Geneticist Ecuadorian emphasizes that cloning projects are also ethical questions. 

"Why do not respect the essence of the animal species?, Do we need to relive?" Asks Paz y Mino. "While it is true that doing so violates the essence of the species, the scientific whim always wanted to demonstrate their ability and progress."

The chronology:

1996 Dolly the sheep was the first mammal cloned from an adult cell. Ryuzo Yanagimachi 1997 The researcher cloned 22 mice alive, with good parenting. 2000 In Scotland also made history and controversy when the first cloned pigs. 2001 On this date, the American researcher Mark Westhusin Copycat created. 2002 cats were obtained and cloned and genetically modified to glow under ultraviolet light. 2003 Futi was created thanks to the DNA of a cow with a record in milk production. 2006 The researcher Hwang Woo-suk cloned the first dog, an Afghan named Snyppy. 2009 In Camel Reproduction Centre in Dubai for the first time cloned a camel. Got 2010 was the first cloned fighting bull in Spain. With it opened the possibility of creating a tissue bank. 2012 The Research Foundation Sooamd Federal University in Seoul and Northeast of Russia initiated a project to clone a mammoth with an Indian elephant.

Science: A drainage system of the brain is discovered.

Neuroscientists Medical Center, of the University of Rochester (USA) have discovered a drainage system by which the brain eliminates waste, according to a study published today in Science Translational Medicine, they expect to have application in Alzheimer's research and Parkinson's. 

The system acts like pipes that leverage the brain's blood vessels and seems to do the same function in the brain that the lymphatic system in the rest of the body, drain waste products. 

The lead author and co Neuromedicina Center at the University of Rochester, Maiken Nedergaard said "waste cleanup is vital to all organs and have long been questions about how the brain gets rid of their waste .

 "This work shows that the brain is being cleaned in a more organized and a much larger scale than was previously believed," Nedergaard said he expressed his wish that this finding is useful for treating brain diseases.

 " We hope that these results have implications for many conditions affecting the brain such as traumatic brain injury, Alzheimer's disease, stroke and Parkinson's disease, "he added. Nedergaard's team has called the new system" the glinfático system "because it acts similarly to the lymphatic system, but is managed by brain cells called glial cells. 

The team made the discovery in mice, whose brains are very similar to the human brain. Scientists have known that CSF has an important role in cleaning the brain tissue, charged with waste products and nutrients to the brain tissue through a process known as diffusion. 

The newly discovered system circulates through all parts of the brain more efficiently through what scientists call the global flow. "It's as if the brain has two garbage collectors - one slow and one fast we knew we just met," Nedergaard said "Given the high rate of metabolism in the brain and high sensitivity, it is not surprising that its mechanisms for disposal of waste is more specialized and extensive than previously thought, "he added.

Scientists warn of possible solar storm in 2014.

An expert panel found that this phenomenon, more and more common, occur within the next two years and may affect global electrical systems and satellites in orbit.

Usually we are used to understand the concept of "natural disaster" in phenomena such as earthquakes, volcanoes, tidal waves and tsunamis. However, a group of NASA scientists warned of an event that is still contingency plans in the world, solar storms.

Solar storms are phenomena which have been heard enough in recent times but could increase with the years.

The panel found that by 2014 the world will face a wave could affect solar electricity systems, communications and satellites around the world.

This could be the biggest event in a cycle of 10 years in the activity of the star and, if filed, would be the first in more than 100 years.

Among the possible consequences that could cause the magnetically charged plasma on earth, is the melting of the electrical transformers in the world, damage satellites and communication systems.

The last solar storm of this magnitude occurred in 1859. At the time, the British astronomer Richard Carrington observed the large solar flare and timed the arrival of geomagnetic storms caused by the phenomenon to Earth with a delay of about 17 hours.

According to reports at the time, the solar storm was so massive that formed northern lights that could be seen much further south than where they usually are.

The question that remains for NASA experts is what the actual impact of a storm of this nature, taking into account the number of satellites in orbit and the effects of their damage globally.

Chile: Astronomers find evidence of dark galaxies.

Astronomers in Chile using a powerful telescope have observed what appears to be evidence of the existence of dark galaxies, the European Southern Observatory (ESO) announced Wednesday.

Dark galaxies are small, gas-rich galaxies from the early universe that are believed to be the building blocks of today's bright, star-filled galaxies, said the ESO, an intergovernmental organization supported by 15 countries.

"For the first time, dark galaxies -- an early phase of galaxy formation, predicted by theory but unobserved until now -- may have been spotted," the ESO said in a statement.

"Using ESO's Very Large Telescope, an international team thinks they have detected these elusive objects by observing them glowing as they are illuminated by a quasar," it said.

The ESO is the most advanced astronomical observatory in the world, and operates three sites in Chile.

The Very Large Telescope (VLT) array -- a cluster of four telescopes that can view objects four billion times fainter than objects visible to the naked eye -- is housed at the ESO's Paranal site in Chile's Atacama Desert.

"Our approach to the problem of detecting a dark galaxy was simply to shine a bright light on it," researcher Simon Lilly said in the release.

"With this study, we've made a crucial step towards revealing and understanding the obscure early stages of galaxy formation and how galaxies acquired their gas," added his colleague, Sebastiano Cantalupo.

The ESO is supported by Austria, Belgium, Brazil, Britain, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden and Switzerland.

An artist's impression released by the European Southern Observatory (ESO) on June 11, 2012 shows the European Extremely Large Telescope (E-ELT) in Chile's Atacama Desert. Astronomers in Chile using a powerful telescope have observed what appears to be evidence of the existence of dark galaxies, the European Southern Observatory (ESO) announced Wednesday.

Hubble telescope finds fifth moon near Pluto.

US astronomers have found a fifth moon orbiting far-away Pluto, NASA said on Wednesday.

The irregular-shaped moon, nicknamed S/2012 for now, is about six to 15 miles (10 to 24 kilometers) across, the US space agency said.

Last year, astronomers reported finding the fourth moon around the icy dwarf planet some three billion miles away.

"The moons form a series of neatly nested orbits, a bit like Russian dolls," said Mark Showalter of the SETI Institute in Mountain View, California.

Pluto's largest moon, Charon, is 648 miles across. The other two, Nix and Hydra, are between 20 and 70 miles in diameter, NASA said.

Hubble -- a potent space telescope that has transformed the field of astronomy since it was first launched in 1990 -- discovered Nix and Hydra in 2005. Astronomers at the US Naval Observatory glimpsed Charon in 1978.

Pluto, once known as the ninth planet from the Sun, was declassified as a full-fledged planet in August 2006 and joined the new category, dwarf planet.

At about 1,430 miles wide, it is about two-thirds the size of the moon and has a mass less than one percent of the Earth's.

Vatican astronomer: alien life is possible although there is no evidence.

Vatican astronomer: alien life is possible although there is no evidence.

The head of the Vatican Astronomical Observatory, Jesuit José Gabriel Funes (pictured), said from Castel Gandolfo (Italy), there are great chances that life exists outside the planet Earth.

In statements to CNA and discussing the possibility of finding intelligent life beyond Earth, the priest said that "it would be the existence of life in the universe."

If so, "Catholics have no need to change our view of the universe," he said, and "God in his freedom, could have created other creatures also smart and be part of creation," he added.

According to P. Funes, these beings "could be related to God, as we have done", and its existence would not be lidiada with the existence of Jesus Christ. "I see no difficulty for the Catholic faith," he said.

The P. Funes said that it comes down to probability. Considering that the universe is made of a hundred billion galaxies and "if we divide the galaxies by the world's population each would play him 14 galaxies, each of these galaxies are made of a hundred billion stars."

It is possible, then, "that each of these stars have planets orbiting other stars, as they do around the Sun and therefore would be the existence of life in the universe."

"There is much to know, because we can reconstruct the history of the universe from the very beginning until the formation of the earth, planets, this is not in contradiction with faith. What we learn the biblical message, and also with reflection theological. What we know by faith, and also by reason, not only by faith that God is the creator, a good father, who sustains us in being in there, "he said.

Within this context, he recalled that the universe "exists thanks to the will of God, and as the Bible says, 'when to finish creating saw that it was good ...', we also have to help us see the goodness of the universe , also look with favor on the history of humanity and our history on earth. "

"Anyway, for now, we have no result. There is no evidence that life exists beyond Earth. This discovery could happen tomorrow. Perhaps a thousand years or may never happen", and "some Once we have evidence that there is life, depends on science, otherwise it is useless to speculate, "he said.

The P. Funes degree in Astronomy in 1985, later joined the Society of Jesus, and after his ordination, his doctorate in astrophysics at the University of Padua, Italy. Subsequently, the superior of his congregation sent him as an astronomer at the Vatican Observatory, and in 2006, Pope Benedict XVI appointed him head of the agency.

For P. Funes, direct the Observatory is a challenge, "because it is acting as a bridge, a bridge between the Catholic Church and scientists, particularly astronomers. It is a challenge that excites, that also allows to reach more audience, because there are issues very interesting, the origin of the universe, the possibility of extraterrestrial life. "

In this regard, said that the relationship between science and faith plays a very important for the Holy Father, "can be seen in his sermons, in his speeches ... especially for the Vatican Observatory and other observatories in the world also 2009 was a very important time because it was the international year for astronomy during that year, the Pope referred several times to astronomy in particular, and in that year, Pope inaugurated the new facilities of the observatory. "

We can say that the origin of the Vatican Observatory, as it is known today, can be set to 1891, when Pope Leo XIII wanted to show that the Church is not opposed to scientific development and, conversely, promotes science high quality.

Today, the Vatican Astronomical Observatory is divided into two groups, one with a historical home in the papal gardens of Castel Gandolfo, and another on Mount Graham, Tucson, Arizona (United States), where researchers, primarily Jesuit priests, have their largest telescope. One of the most important astronomical centers in the world.

Scientists convert skin cells in heart muscle.
LONDON, May 28. 12 (CNA / EWTN News). - A group of scientists succeeded in Haifa (Israel), remove skin cells from two men with heart failure 51 and 61 years and turn them into heart muscle.
The study was released Wednesday by the journal "European Heart Journal." The team said that clinical trials of the technique could begin within 10 years.
Lior Gepstein, the "Institute of Technology Technion-Israel and author of the research, said it has been shown" that you can take skin cells from an elderly patient with advanced heart failure and end up getting in the laboratory cells that beat, healthy and youngequivalent to their heart cells when just born. "
Reportedly, the scientists studied for over ten years, stem cells from various sources to capitalize on its ability to transform into a variety of other cell types and treat various diseases.
There are two main forms of stem cells, embryonic death involving embryonic and adult and induced pluripotent (iPS called), which usually come from the skin or the blood and do not involve ethical issues.
In statements to CNA, the specialist in medical genetics, Yasser Sullcahuamán, highlighted the use of adult stem cells because they create an ethical conflict.
"They do a lot of work to avoid this ethical problem where an individual (embryo) becomes a means not an end," he said. He said that the dignity of the embryo is protected not only "by the Church, but for us as human beings, respect for the individual as part and supreme goal of society."
Sullcahuamán, who works at the National Institute of Diseases Neeoplásicas (INEN) of Peru, said that life begins at the time of fertilization. "Therefore we could not manipulate embryonic stem cells," he said.
The scientist said that "we could handle another group of cells that are just as promising as are stem cells that originate from adult tissues, where there would be no ethical confrontation of any kind because they are cells that we are going to differentiate and which could cure many diseases, including diabetes, heart attack or stroke. "
This is not the first science to adult stem cells. In April 2007 a team of scientists led by Sir Magdi Yacoub in London managed to create a fabric that works as a heart valve based on adult stem cells.
Also in March 2009 it was announced that the girl Dakota Clarke, two years old, recovered his sight by treatment with adult stem cells from umbilical cord. Treatment provided in a hospital in Qingdao, China.
