Is it a solar cell? Is it a rechargeable battery? Well, technically it’s both.

The scientists at Ohio State University have developed the world’s first solar battery that can recharge itself using light and air. The findings from the patent-pending device were published in the October 3, 2014 issue of the journal Nature Communications.

This from Ohio State University:

Key to the innovation is a mesh solar panel, which allows air to enter the battery, and a special process for transferring electrons between the solar panel and the battery electrode. Inside the device, light and oxygen enable different parts of the chemical reactions that charge the battery.

The university plans to license the solar battery to industry.

“The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy,” said Yiying Wu, professor of chemistry and biochemistry at Ohio State University. “We’ve integrated both functions into one device. Any time you can do that, you reduce cost.”

The device also tackles the issue of solar energy efficiency by eliminating the loss of electricity that normally occurs when electrons have to travel between a solar cell and an external battery. Where typically only 80 percent of electrons make it from the solar cell into the battery, the new solar battery saves nearly 100 percent of electrons.

The 2014 Nobel Prize in Physics has been awarded to Shuji Nakamura, professor of materials and of electrical and computer engineering at the University of California and 2010 ECS Plenary speaker.

The prize is for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources, and is shared with ECS member Isamu Akasaki of Meijo University and Nagoya University, Japan; and Hiroshi Amano of Nagoya University.

In his plenary talk at the 218th ECS Meeting in Las Vegas, Nevada, Nakamura described the current status of III-nitride based light emitting diodes (LEDs) and laser diodes. Nitride-based white LEDs have been used for many application such as LCD TV backlight, lighting for inside/outside applications and others.

According to the Royal Swedish Academy of Sciences, when Nakamura, Akasaki and Amono “produced bright blue light beams from their semiconductors in the early 1990s, they triggered a fundamental transformation of lighting technology. Red and green diodes had been around for a long time, but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.”

The LED lamp “holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids,” the academy continued.

A paint-on, see-through bandage – fully equipped with oxygenation sensors – has been developed with the purpose of better aiding wounded soldiers and improving the success of surgeries to restore limbs and physical functions.

Not only does it protect wounds and burns as any bandage should, but it also enables direct measurement and mapping of tissue oxygen.

The “smart” bandage was developed by an international, multidisciplinary team of researchers led by Assistant Professor Conor L. Evans at the Wellman Center for Photomedicine of Massachusetts Generall Hospital (MGH) and Harvard Medical School (HMS). The group’s findings have been recently published in The Optical Society’s (OSA) open-access journal Biomedical Optics Express.

This from The Optical Society:

Now, the “smart” bandage developed by the team provides direct, noninvasive measurement of tissue oxygenation by combining three simple, compact and inexpensive components: a bright sensor molecule with a long phosphorescence lifetime and appropriate dynamic range; a bandage material compatible with the sensor molecule that conforms to the skin’s surface to form an airtight seal; and an imaging device capable of capturing the oxygen-dependent signals from the bandage with high signal-to-noise ratio.

With our Energy and Water Summit right around the corner, we’ve only got one thing on our mind: poop.

Forty percent of the world’s population – 2.5 billion people – practice open defecation or lack adequate sanitation facilities, and the consequences can be devastating for human health as well as the environment.

The Electrochemical Society and the Bill & Melinda Gates Foundation know there is no easy solution to this problem, but we are dedicated to finding and funding innovative research to reinvent the sanitation infrastructure.

In Francis de los Reyes’ TEDTalk entitled, “Sanitation is a basic human right,” the environmental engineer and sanitation activist makes his case for the total reinvention of the sanitation landscape as we know it.

“For the past 14-years, I’ve been teaching crap,” Reyes says.

And that he has. Reyes has dedicated his time to studying and researching human waste. The problem is especially relevant in India, where open deification is putting citizens at major health risks.

This from Reuters:

Less than a third of India’s 1.2 billion people have access to sanitation and more than 186,000 children under five die every year from diarrheal diseases caused by unsafe water and poor sanitation, according to the charity WaterAid.

The United Nations said in May half of India’s people defecate outside – putting people at risk of cholera, diarrhea, dysentery, hepatitis A and typhoid.

Read the full article here.

With India accounting for 818 million of the 2.5 billion people who lack adequate sanitation, most of the country’s rivers and lakes are polluted with sewage and industrial effluents.

So why can’t we just build western style flush-toilets in countries such as India?

“It’s just not possible,” Reyes says.

In these developing worlds, there is often time not enough water or energy to take on such a feat. Also, laying out sewer lines would cost governments tens of trillions of dollars.

Through our partnership with the Bill & Melinda Gates Foundation, we hope to help solve these issues.

Scientists at the University of Rochester have developed a real-world invisibility cloak. This Harry Potter-esque cloak has the ability to hide objects from view, and is surprisingly inexpensive due to the readily available materials in its novel configuration.

“There’ve been many high tech approaches to cloaking and the basic idea behind these is to take light and have it pass around something as if it isn’t there, often using high-tech or exotic materials,” said John Howell, a professor of physics at the University of Rochester.

The Rochester Cloak is different from its predecessors, because unlike invisibility cloaks of the past, this cloak maintains an object’s invisibility even when the viewer changes his or her angle and creates a different viewpoint.

“This is the first device that we know of that can do three-dimensional, continuously multidirectional cloaking, which works for transmitting rays in the visible spectrum,” said Joseph Choi, a PhD student at Rochester’s Institute of Optics who is working with physics professor John Howell at the university.

A group of Swedish-based academics have been in a heated competition for the past 17 years – a competition over who can sneak the most Bob Dylan lyrics into articles, that is.

A group of five scientist from the Karolinska Institutet have revealed their long-running race to quote Dylan as many times as possible before retirement. The victor is to be awarded a free lunch at a local restaurant.

The competition began in 1997 after John Lundberg and Eddie Weitzberg published “Nitric Oxide and Inflammation: The Answer Is Blowing In the Wind” in Nature.

“We both really like Bob Dylan so when we set about writing an article concerning the measurement of nitric oxide gas in both the respiratory tracts and intestine, with the purpose of detecting inflammation, the title came up and it fitted there perfect,” says Weitzberg.

A few years later, the two saw an articles titled, “Blood on the Tracks: A Simple Twist of Fate,” by Jonas Frisen and Konstantinos Meletis. With this double Dylan reference, Lundberg and Weitzberg could not resist the competition. Shortly after, the two introduced “The times they are a-changin’” into an article and the battle was on.

This from The Guardian:

Word spread quickly through Stockholm’s Karolinska Institute, where all four men work, and before long there was a fifth competitor: Kenneth Chien, a professor of cardiovascular research, who is also keen to win a free lunch. By the time he met the others, he already had one Dylan paper to his name – Tangled Up in Blue: Molecular Cardiology in the Postmolecular Era, published in 1998. With five competing rivals, the pace of Dylan references accelerated. Lundberg and Weitzberg’s The Biological Role of Nitrate and Nitrite: The Times They Are a-Changin’, in 2009; Eph Receptors Tangled Up in Two in 2010; Dietary Nitrate – A Slow Train Coming, in 2011.

Read the full article here.

Weitzberg explained in an interview with The Local that they didn’t quote Dylan with strict scientific papers, only articles wrote about research by others, book introductions, and editorials.

Take a listen to the playlist we’ve compiled of some of the Dylan tracks that inspired these scientists.

“Stella” is the name on every climate-cautious, pollution-loathing environmentalist’s lips.

Who is Stella? Well, she’s a car.

She may not be “pretty” by conventional standards, but Stella is the first family car powered by solar energy. The car – driven by a team of students from Eindhoven University of Technology – has just finished its road trip from Los Angeles to San Francisco, fueled solely by the California sunshine.

While the car is capable of traveling 500 miles (800km) on a single charge and can clock up to 80 miles per hour, there is still one pressing question on everyone’s mind – who will drive it?

“Do you want it in your daily life? Would you want to take it to get groceries?” asked one of Stella’s drivers, Jordy de Renet, in an interview with Popular Science.

The car’s strange shape stems from a compromise for aerodynamics and allowing comfort for at least two people. Also, the wedge-shaped vehicle’s flat surface allows for more solar cell coverage.

This from Popular Science:

Stella is CO2-neutral and the first energy-positive car in the world. The solar array charges while the car is in motion as well as when it is parked. “We get more energy out of the car than is needed to drive it,” said de Renet. That power, as much as twice what the car uses, can be returned to the grid.

A team of scientists have recently discovered how to produce ultra-thin “diamond nanothreads.” These nanothreads, which construct a structure more than 20,000 times smaller than average human hair, are expected to yield extraordinary properties. The new nanothreads will be stronger and stiffer than current nanotubes, and they will also be light in weight.

This means creating the potential for more fuel efficient vehicles, and even fictional-sounding endeavors – such as a “space elevator.”

This from Carnegie Science:

The team—led by John Badding, a chemistry professor at Penn State University and his student Thomas Fitzgibbons—used a specialized large volume high pressure device to compress benzene up to 200,000 atmospheres, at these enormous pressures, benzene spontaneously polymerizes into a long, thin strands of carbon atoms arranged just like the fundamental unit of diamond’s structure—hexagonal rings of carbon atoms bonded together, but in chains rather than the full three-dimensional diamond lattice.
