ECS senior vice president and professor at the University of Texas at Arlington, Krishnan Rajeshwar, recently visited the University of Iowa’s ECS Student Chapter to discuss research, meet with faculty, and deliver a lecture on solid state materials.

Rajeshwar’s research touches areas ranging from the first demonstrated use of ionic liquid electrolytes for electrode stabilization in photoelectrochemical (PEC) devices to novel approaches to the electrosynthesis of binary and ternary semiconductor thin films.

Recently, his studies have addressed the use of solid state chemistry principles to the design of electrodes for energy conversion and solar fuel generation. Rajeshwar applied some of these concepts to his lecture, “In a Solid State Materials Chemistry Wonderland: A 40-Year Odyssey,” which he delivered to the ECS Student Chapter at the University of Iowa.

Throughout his visit, Rajeshwar met with the faculty from the university’s departments of chemistry and engineering, discussed science and current events with student members, and was hosted to dinner by ECS 2nd vice president Johna Leddy.

A recent pistachio recall is bringing Salmonella and other foodborne illnesses back into the national spotlight. The popularity of the in-shell pistachio brands recalled paired with the long shelf-life of the nut has health experts concerned for the potential of the foodborne illness to spread rapidly. Many are again asking: 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,” Horikawa, Postdoctoral researcher at Auburn University and member of ECS, says.

Horikawa and his team’s concept revolves around the placement of a tiny biosensor—a sensor so small that it’s nearly invisible to the human eye—on the surface of fresh fruits and vegetables to detect the presence of pathogenic organisms such as Salmonella. This on-site, robust detection method utilizes magnetoelastic (ME) materials that can change their shape when a magnetic field is applied. The materials respond differently to each magnetic field, changing their shapes accordingly. This allows the researchers to detect if a specific pathogen—such as Salmonella—has attached to the biosensor.

The 2015 Outstanding Student Chapter Award Recipient 

The 2015 ECS Outstanding Student Chapter Award recipient was Indiana University. Founded in 2015, Indiana University brings together members from a variety of research backgrounds such as mechanistic organic, environmental, bioanalytical, and materials, to promote interdisciplinary discussions about electrochemistry and solid state science. Led by faculty advisors Professor Dennis Peters and Professor Lane Baker, this group has hosted guest speakers, including Allen J. Bard and Nate Lewis, on their campus to not only present seminars, but also give career advice. The mission of the Indiana Student Chapter is to spread knowledge of electrochemical science to the younger members of their community.

Together with his team, ECS member Wolfgang Schuhmann develops new electrodes, for the production of hydrogen.

New research out of Ruhr Universitaet Bochum is showing big gains for water electrolysis, with new efficiency levels double that of previous efforts.

By applying a layer of copper atoms in conventional platinum electrodes, researchers were able to desorption easier for the catalyst surface. This system then generated twice the amount of hydrogen than a platinum electrode without a copper layer.

This breakthrough could help water electrolysis gain a better reputation as a method for hydrogen production. Prior to this breakthrough, too much energy was lost in the process to prove it efficient. Now, the efficiency level has been doubled.

This from Ruhr Universitaet Bochum:

The researchers modified the properties of the platinum catalyst surface by applying a layer of copper atoms. With this additional layer, the system generated twice the amount of hydrogen than with a pure platinum electrode. But only if the researchers applied the copper layer directly under the top layer of the platinum atoms. The group observed another useful side effect: the copper layer extended the service life of the electrodes, for example by rendering them more corrosion-resistant.

“To date, hydrogen has been mainly obtained from fossil fuels, with large CO2 volumes being released in the process,” said Wolfgang Schuhmann, ECS member and lead author of the study. “If we succeeded in obtaining hydrogen by using electrolysis instead, it would be a huge step towards climate-friendly energy conversion. For this purpose, we could utilize surplus electricity, for example generated by wind power.”

Measuring the pH level of a solution is usually a relatively simple process. However, that process begins to get more complicated as things get smaller.

Examining changes in acidity or alkalinity at the nanoscale, for example, has been a nearly impossible feat for researchers. Now, a team from the Polish Academy of Sciences in Warsaw, including 11 year ECS member Gunter Wittstock, has developed a novel method of pH measurement at the nanoscale.

The group has developed a nanosensor with the ability to continuously monitor changes in pH levels.

This from the Polish Academy of Sciences in Warsaw:

Used as a scanning electrochemical microscope probe, it allows for the precise measurement of changes in acidity/alkalinity occurring over very small fragments of the surface of a sample immersed in a solution. The spatial resolution here is just 50 nm, and in the future, it can be reduced even further.

Read the full article.

“The ability to monitor changes in the acidity or alkalinity of solutions at the nanoscale, and thus over areas whose dimensions can be counted in billionths of a meter, is an important step toward better understanding of many chemical processes. The most obvious examples here are various kinds of catalytic reactions or pitting corrosion, which begins on very small fragments of a surface,” said Marcin Opallo, lead author in the study.

The team hopes that this new method could lead to monitoring of pH changes taking place in the vicinity of individual chemical molecules.

An interdisciplinary team, including 32 year ECS member Stuart Licht and ECS student member Matthew Lefler, has developed a way to make electric vehicles that are not only carbon neutral, but carbon negative – capable of reducing the amount of atmospheric carbon dioxide as they operate by transforming the greenhouse gas.

By replacing the graphite electrodes that are currently being used in the development of lithium-ion batteries for electric cars with carbon materials recovered from the atmosphere, the researchers have been able to develop a recipe for converting collected carbon dioxide into batteries.

This from Vanderbilt University:

The team adapted a solar-powered process that converts carbon dioxide into carbon so that it produces carbon nanotubes and demonstrated that the nanotubes can be incorporated into both lithium-ion batteries like those used in electric vehicles and electronic devices and low-cost sodium-ion batteries under development for large-scale applications, such as the electric grid.

Read the full article.

The research is not the first time scientists have shown progress in collecting and converting harmful greenhouse gases from the environment.

Typically, carbon dioxide conversion revolves around transforming the gas into low-value fuels such as methanol. These conversions often do not justify the costs.

However, the new process produces better batteries that are not only expected to be efficient, but also cost effective.
