A 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.

Since 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 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.

Topic Close-up #5

SYMPOSIUM I05: Heterogeneous Functional Materials for Energy Conversion and Storage.

FOCUSED ON the science that controls emergent properties in heterogeneous functional materials as a foundation for design of functional material devices with performance not bounded by constituent properties.

PROVIDING a unique venue for both contributed and invited speakers to present the latest advances in novel modeling approaches, advanced 3-D imaging and characterization techniques, novel material synthesis and manufacturing methods to create highly ordered material structure, and applications of heterogeneous functional materials in devices for energy conversion and storage. This symposium especially encourages and welcomes contributed presentations.

The 2015 MacArthur Foundation geniuses have just been revealed, with seven prolific scientists receiving the prestigious title. Of those scientists, inorganic chemist Peidong Yang was named as one of this year’s geniuses for his pioneering work in nanomaterials science. His work is not only transformative for the science of semiconductor nanowires and nanowire photonics, it is also opening new paths for clean, renewable energy.

His research has led to innovative commercial productions for the conversion of waste heat to electricity, chemical sensors, and optical switches. Currently, Yang’s focus is directed toward artificial photosynthesis, where he and his research group have created a synthetic “leaf” that is a hybrid system of semiconducting nanowires and bacteria.

Scott Lillard is currently the Professor & Carboline Endowed Chair in Corrosion at the University of Akron, where he leads academic research and is and major contributor to the establishment the university’s new Corrosion Engineering program. He has recently been appointed to the ECS Electrochemical Science & Technology (EST) Editorial Board as an Associate Editor for a two-year term beginning July 1, concentrating in the Corrosion Science and Technology Technical Interest Area.

What do you hope to accomplish in your new role as the EST Editorial Board Associate Editor?
I have some experience working on the board of some other journals, but I don’t think that’s what I really contribute. What I contribute is this idea of customer service. There are a number of reasons why people publish in the journal. It might be the appropriateness of the content or the impact factor, but the third reason is probably customer service. What does that mean? That means getting good peer reviews in a timely manner and treating the authors in a professional manner.

How do you think peer reviewed journals have changed over the years?
I think the goals of authors are the same as they were 20 years ago. They want to get their publication out to people in their field so they can read it. They want to do that in as timely a manner as possible. The way in which the process is expected to occur is much different now than it was 20 years ago. It would take you six or nine months to get reviews back. That’s just not expected anymore. Everything is expected to be much more efficient now. I think efficiency, speed, and customer service are the things that are changing.

September 28-October 2, 2015 is the first Peer Review Week, and it’s a good a time to put a spotlight on good practice in peer review and celebrate all it brings to the scholarly communication process. At ECS, we are marking Peer Review Week with a look at how peer review works here, and what happens to your manuscript after you submit it.

Our authors already know that the preparation and submission of a scientific manuscript for peer review can be a lengthy process, involving not just the research work and writing of the paper, but also the collection of supporting pieces of information required to enable publication.

But what happens after you hit the “Submit” button?
