In a response to a recent call for photos, Galina Strukova sent us some great shots of the microworld of palladium-nickle alloy.

You’re looking at pictures of real objects of the palladium-nickel alloy, the size of the samples ranging from tens of micrometers to 1-2 millimeters.

They are produced via self-organization of nano-sized (several nanometer in diameter) wires growing on porous membranes under the action of electric current pulses. The authors have managed to isolate and photograph them by means of a modern electron microscope. They have described this 3D sculptures in scientific journals.

Such antenna-like samples are expected to find application in nanotechnology. Now we can produce such “sculptures” from various metals “by order,” examine them and admire their elegant forms.

However, it is still a riddle. Why does it so closely resemble plants and seashells? Does this mysterious self-organization have anything in common with formation of plant leaves, fungi, and seashells?

Read Strukova and Strukov’s previous installment, “The Beauty and Mystery of the Microworld.”

ECS Takes Down the Paywall for OA Week

oa_week_reg2ECS is celebrating Open Access Week this year by making all the content—over 120,000 articles—in the ECS Digital Library freely accessible from October 19 through 25, 2015.

The ECS Digital Library is home to the Journal of The Electrochemical Society, the flagship journal of ECS, published continuously since 1902, and to the ECS Journal of Solid State Science and Technology, ECS Electrochemistry Letters, ECS Solid State Letters, Electrochemical and Solid-State Letters, ECS Transactions, ECS Meeting Abstracts, and Interface.

We have been increasing the number of articles we publish as open access at no cost to the author for almost two years now, but we wanted to take the opportunity of Open Access Week to show the world our vision: all of our content freely available to anyone who wants to read it.

The research in these journals directly addresses the sustainability of our planet. Our scientists are looking to solve some of the most pressing problems the world is facing today:

  • energy storage and conversion, from small-scale to large scale: batteries, fuel cells, biofuels, supercapacitors, grid-scaling;
  • environmental remediation of materials used in research;
  • corrosion of infrastructures;
  • clean water and sanitation;
  • the growth of nanotechnology;
  • processes to develop safer and more effective drugs;
  • improving and developing new medical devices; and
  • sensors for environmental cleanup, emissions monitoring, detection of illegal and dangerous materials, home and workplace safety, and medical diagnosis and care.

ECS believes that open access—especially in electrochemistry and solid state science—is an important goal for scientific and technological development and, quite simply, creating a better world.

Ensuring that everyone working on these issues—wherever they are in the world, and for whomever they work—has access to the latest research is in our best interests as a nonprofit professional society supporting researchers everywhere, and in the best interests of all the sciences.

ECS has not yet reached a place where it can sustainably make all of its publications open access, but it is our goal and we want to celebrate our vision of the future during Open Access Week.

Take advantage of the free content in the ECS Digital Library October 19 through 25, 2015.

trees_to_power2Researchers are not only looking for alternative ways to generate energy, they’re also looking for alternative ways to store it. From ECS member Vilas Pol’s packing peanut batteries to innovative flow batteries; scientists are looking for a way to securely store and deliver clean energy to the grid.

Now, engineers from McMaster University are turning trees into energy storage devices that could potentially power everything from small electronic devices to electric vehicles. With any luck, this technology could be taken to large-scale grid applications.

This from McMaster University:

The scientists are using cellulose, an organic compound found in plants, bacteria, algae and trees, to build more efficient and longer-lasting energy storage devices or capacitors. This development paves the way toward the production of lightweight, flexible, and high-power electronics, such as wearable devices, portable power supplies and hybrid and electric vehicles.

WEB-salmonella-cucumber-c-1020x1028A nationwide outbreak of Salmonella-tainted cucumbers has afflicted states with increased illnesses and hospitalizations. While the U.S. Food and Drug Administration (FDA) has determined the source and cause of the outbreak, the damage has been done, and the case count is expected to rise in spite of the recent recall. Many are now asking the question: how can we better control food safety?

Shin Horikawa and his team at Auburn University believe their novel biosensor technology could resolve many of the current issues surrounding the spread of foodborne illnesses. As the principal scientist for a concept hand-picked for the FDA’s Food Safety Challenge, Horikawa is looking to make pathogen detection faster, more specific, and cheaper.

Faster, Cheaper, Smarter

“The current technology to detect Salmonella takes a really long time, from a few days to weeks. Our first priority is to shorten this detection time. That’s why we came up with a biosensor-based detection method,” says Horikawa, Postdoctoral researcher at Auburn University and member of ECS.

Developing Carbon Nanotube Transistors

carbon_nanotubesx519Since the development of the transistor in 1947, the semiconductor industry has been working to rapidly and continuously improve performance and processing speeds of computer chips. Following Gordon Moore’s iconic law—stating that transistor density would double every two years—the semiconducting silicon chip has propelled technology through a wave of electronic transformation.

Next Electronics Revolution

But all good things must come to an end. The process of packing silicon transistors onto computer chips is reaching its physical limits. However, IBM researchers state that they’ve made a “major engineering breakthrough” that provides a viable alternative to silicon transistors.

The team from IBM proposes using carbon nanotube transistors as an alternative, which have promising electrical and thermal properties. In theory, carbon nanotube transistors could be much faster and more energy efficient than currently used transistors. Nanotube transistors have never been utilized in the past due to major manufacturing challenges that prevented their wide-spread commercialization. However, the IBM researchers are combating this issue by combining the nanotubes with metal contacts to deliver the electrical current.

Research out of the Institut National de la Recherche Scientifique (INRS) has yielded a novel micro-supercapacitor that has reportedly reached an energy density 1,000 times greater than current electrochemical capacitors.

This unmatched energy storage performance was made possible through a new electrode, producing density levels comparable to that of current lithium-ion micro-batteries.

Applications of this new technology could range from small electronics to autonomous sensor networks, opening the door to better water quality and air pollution monitoring.

“The extent of the electrode’s surface and the presence of pores of various sizes are key to a large storage capacity. We designed this new 3D electrode using an electrochemical process to synthesize a very porous gold structure. Ruthenium oxide, a pseudocapacitative material featuring high electrical conductivity and very good cyclability, was then inserted into the structure, resulting in unsurpassed energy density. For this type of application, component sizes are reduced to a few square millimeters, making it possible to use such expensive materials,” said Daniel Guay, ECS member and co-author of the study.

Peer Review Week: Tips for Peer Reviewers

Peer Review Week is still going strong, with publishers and reviewers across the globe chiming in with astute articles and intelligent commentary. Here at ECS, we’ve gotten insight from one of our associate editors, looked at how the peer review process works, and examined how it has become the heart of scholarly publication.

Now we’d like to take a moment to thank our reviewers, who use their technical expertise to help us maintain high-quality publication standards in all four of our peer reviewed journals. Take a look at these tips for peer reviewers.
