One of the biggest barriers between renewables and widespread grid implementation has been the issue of intermittency. How can we meet a nation’s energy demands with solar when the sun goes down?

In an effort to move past these barriers toward a cleaner energy infrastructure, a new paper published in the Journal of The Electrochemical Society describes an effective, low-cost solution for storing solar energy.

The research team from Ecole Polytechnique Fédérale de Lausanne is looking to covert solar energy into hydrogen through water electrolysis. At its core, the concept revolves around using solar-produced electricity to split water molecules into hydrogen and oxygen, leaving clean hydrogen to be stored as future energy or even as a fuel.

But this idea is not new to the scientific community. However, the research published in JES provides answer to continuous barriers in this field related to stability, scaling, and efficiency.

NASA recently announced that all research funded by the space agency will be accessible to anyone looking to access the data at absolutely no cost.

The new public web portal, called PubSpace, was established in response to NASA’s new policy, which requires that all research funded by NASA and published in peer-reviewed journals must be open to the public within one year of its initial publication.

“At NASA, we are celebrating this opportunity to extend access to our extensive portfolio and scientific and technical publications,” NASA Deputy Administrator Dava Newman said in a press release. “Through open access and innovation we invite the global community to join us in exploring Earth, air, and space.”

However, the entire body of NASA-funded research will not be accessible in PubSpace. Materials and patents governed by personal privacy, proprietary, or security laws will not be housed in the new database.

NASA’s new policy and PubSpace is a direct response to a request from the White House Office of Science and Technology Policy for federal funding agencies to make papers and data more easily accessible to other researchers and the public.

A large-scale study on the impact of open access has recently been released, finding that OA papers have a 50 percent greater citation advantage than papers published in subscription-based journals.

The analysis of more than three million papers determined that a journal’s move toward open access publishing is necessary to retain relevance in the field. Additionally, further results point to the face that traditional subscription-based journals will lose their relevance for researchers and governments if they continue to block access to research via paywalls.

This from Digital Journal:

The new research also shows that the widely held belief that open access papers have a greater impact due to them being available earlier than their commercially published versions is not consistent with the large-scale data collected by 1science. In fact, based on a tie series comprising more than 17.4 million papers published between 2000 and 2015, it is clear that open access still suffers from the effect of embargoes enforced by traditional publishers who maintain that they require that delay to keep the subscription model alive.

Enzyme-based sensors detect lactate levels in sweat

It may be clammy and inconvenient, but human sweat has at least one positive characteristic – it can give insight to what’s happening inside your body. A new study published in the ECS Journal of Solid State Science and Technology aims to take advantage of sweat’s trove of medical information through the development of a sustainable, wearable sensor to detect lactate levels in your perspiration.

“When the human body undergoes strenuous exercise, there’s a point at which aerobic muscle function becomes anaerobic muscle function,” says Jenny Ulyanova, CFD Research Corporation (CFDRC) researcher and co-author of the paper. “At that point, lactate is produce at a faster rate than it is being consumed. When that happens, knowing what those levels are can be an indicator of potentially problematic conditions like muscle fatigue, stress, and dehydration.”

Utilizing green technology

Using sweat to track changes in the body is not a new concept. While there have been many developments in recent years to sense changes in the concentrations of the components of sweat, no purely biological green technology has been used for these devices. The team of CFDRC researchers, in collaboration with the University of New Mexico, developed an enzyme-based sensor powered by a biofuel cell – providing a safe, renewable power source.

Biofuel cells have become a promising technology in the field of energy storage, but still face many issues related to short active lifetimes, low power densities, and low efficiency levels. However, they have several attractive points, including their ability to use renewable fuels like glucose and implement affordable, renewable catalysts.

Overcoming barriers in scholarly publishing

In 1995, Forbes published an article entitled, “The Internet’s first victim?” In the article, author John Hayes predicted the world of commercial, for-profit scholarly publishing would suffer under the thumb of the internet and begin the slow process of fizzling out for lack of ability to turn a profit.

Turns out he was wrong.

Commercial scientific publishing has adapted to the times, becoming a multi-billion dollar industry; a $25.2 billion industry to be exact.

The rise of the for-profits

According to CBC News, the top for-profit scientific publishers report profit margins of nearly 40 percent, making some of those margins even higher than that of companies like Apple and Google.

The divide between ECS publications and that of top commercial publishers has deep roots. In the early days of scientific publishing, most journals came out of nonprofit scientific societies like ECS. However, the digital age changed things. It did not stifle the commercial publisher as Hayes thought, instead it hurt the scientific societies. Because the cost to make the switch from print to digital was so high, many societies sold their journals to large, for-profit publishers.

The top five largest, for-profit, academic publishers now publish 53 percent of all scientific papers in natural and medical sciences, but ECS still remains as one of the last independent scientific society publishers, and is still committed to the initial vision of the journals: to disseminate scientific research to the broadest possible audience with the fewest barriers.

Now that more and more publishers are requiring ORCID iDs, and with the advent of ORCID’s Collect & Connect program, ORCID has been receiving an onslaught of questions about how to properly display ORCID iDs.

When ORCID first released its guidelines on collection and display in 2013, the publishing environment was very different and ORCID was still very young. The constantly changing publishing landscape coupled with the widespread uptake of ORCID iDs has created a need to reevaluate these practices and address any gaps or frequently asked questions.

In order to accomplish this, ORCID has gathered a group of publishing professionals to look at the document and create recommendations for a new set of guidelines. To be successful, these professionals must use their publishing experience, coupled with suggestions from the community. (more…)
