Edward Goodrich Acheson (1856-1931), one of the charter members of ECS, is best known for having invented and commercialized carborundum, an artificial graphite.

Biography

Acheson was born in southwestern Pennsylvania and raised its coal fields. At the age of 16, after his father died, he left school to help support his family. Nevertheless, Acheson devoted his nights to the scientific endeavors, especially electrical experiments.

In 1880, Acheson attempted to sell a battery of his own invention to Thomas Edison, who ended up hiring him to assist with his research. He experimented with creating a conducting carbon that Edison could use in his electric light bulbs.

After working for Edison for four years, Acheson left his employ to become an independent inventor. In 1891, Acheson acquired access to an electric
generating plant and attempted to use electric heat to impregnate clay with carbon. What resulted from this experiment was his discovery of a crystalline substance that had value as an abrasive, which Acheson named “carborundum” (also known as silicon carbide).

In 1894, he established the Carborundum Company in Monongahela City, Pennsylvania, which created grinding wheels, whet stones, knife sharpeners, and powdered abrasives. Later, Acheson used his electric furnace to produce artificial graphite, which  he commercialized, discovering that various organic substances allowed colloidal suspension of particles of graphite mixed in oil or water.

Acheson received 70 patents related to abrasives, graphite products, reduction of oxides, and refractories. ECS awarded him the first Acheson Award, named in his honor, in 1931.

Research highlighting transformative scientific discoveries

ECS published its first Editors’ Choice article on Tuesday, March 22, 2016 in the Journal of The Electrochemical Society. The article, entitled “Communication—Comparison of Nanoscale Focused Ion Beam and Electrochemical Lithiation in β-Sn Microspheres,” details transformative findings in the dosage and spatial distribution of lithiation.

Editors’ Choice articles are a special designation of ECS’s newly established Communication articles, which are designed to highlight breakthrough preliminary research and bolster the scientific discovery process. ECS journal editors designate exemplary Communication articles as Editors’ Choice when the research presented is transformative, detailing either novel advancements in a field or completely new discoveries.

“This paper introduces the use of a focused Li-ion beam (Li-FIB) as a new tool that is designed to probe lithiation mechanism at the nanoscale,” says Nick Wu, Associate Editor of the Journal of The Electrochemical Society. “This technique, which employs a focused Li-ion beam with spot size of a few tens of nanometers and kinetic energy of a few keV, enables precise dosage and spatial distribution of lithiation.”

Papers chosen as Editors’ Choice are regarded as having the highest quality, impact, significance, and scientific or technological interest to electrochemical and solid state science and technology. In order to disseminate these findings to the scientific community at large and open the door to faster developments of practical applications, all Editors’ Choice articles are published Open Access.

“Furthermore,” Wu says, “lithiation in this technique is carried out in the absence of electrolytes so that it allows the study of lithiation dynamics solely in the bulk or surface layers (coatings) of the electrode material without the confounding influences from the electrolyte interactions.”

Each paper undergoes the same rigorous peer-review process associated with ECS journals, with Editors’ Choice articles showing extraordinary direction, concept, interpretation, field, or way of doing something.

Rooftops can provide more than shelter from the elements; they may also provide a goldmine of untapped energy production.

The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recently issued a report stating that rooftop solar panels have the potential to power nearly 40 percent of the U.S.

“It is important to note that this report only estimates the potential from existing, suitable rooftops, and does not consider the immense potential of ground-mounted PV,” co-author of the report Robert Margolis said. “Actual generation from PV in urban areas could exceed these estimates by installing systems on less suitable roof space, by mounting PV on canopies over open spaces such as parking lots, or by integrating PV into building facades. Further, the results are sensitive to assumptions about module performance, which are expected to continue to improve over time.”

Essentially, solar panels could have limitless possibles. However, land is a precious commodity. Roofs, however, provide a space that typically goes unused to generate a huge amount of power for the U.S.

A research team aims to make a battery and solar cell hybrid out of two single systems.

People across the globe are looking toward renewable solutions to change the landscape of energy. But what happens when the sun goes down and the wind stops blowing? In order to guarantee green energy that is consistent, reliable energy storage systems are critical.

“Currently, single systems of photovoltaic cells which are connected together — mostly lead-based batteries and vast amounts of cable — are in use,” said Ilie Hanzu, TU Graz professor and past member of ECS. “We want to make a battery and solar cell hybrid out of two single systems which is not only able to convert electrical energy, but also store it.”

The idea of a battery and solar cell hybrid is completely novel scientific territory. With this project, entitled SolaBat, the team hopes to develop a product that has commercial applications. For this, the scientists will have to develop the perfect combination of functional materials.

“In the hybrid system, high-performance materials share their tasks in the solar cell and in the battery,” Hanzu said. “We need materials that reliably fulfill their respective tasks and that are also electrochemically compatible with other materials so that they work together in one device.”

In an effort to move away from fossil fuels toward a renewable future, researchers have invested time and resources into developing hydrogen fuel. The most efficient way to create this sustainable fuel has been through water-splitting, but the process is not perfect. Now, researchers from MIT, the Skoltech Institute of Technology, and the University of Texas at Austin believe they may have made a breakthrough that could lead to the widespread adoption of water-splitting to produce hydrogen fuel.

The key discovery in the paper published in Nature Communications is the mobilization of oxygen atoms from the crystal surface of perovskite-oxide electrodes to participate in the formation of oxygen gas, which can speed up water-splitting reactions.

The breakthrough could be a crucial step in helping the energy infrastructure efficiently move away from traditional energy sources to renewables.

“The generation of oxygen from water remains a significant bottleneck in the development of water electrolyzers and also in the development of fuel cell and metal-air battery technologies,” said J. Tyler Mefford, current ECS member and lead author of the study.

But the new results didn’t come out of the woodwork. The data illustrates collaborative work across experimental and theoretical fields. The new work essentially explains over 40 years of theory and experiments, looking at why some approaches worked and others failed.

“If we could develop catalysts made with Earth-abundant materials that could reversibly and efficiently electrolyze water into hydrogen and oxygen, we could have affordable hydrogen generation from renewables — and with that, the possibility of electric cars that run on water with ranges similar to gas powered cars,” Mefford said.

Glucose monitoring has had a long history with electrochemical science and technology. While ECS Honorary Member Adam Heller’s continuous glucose monitoring system for diabetes management may be the first innovation that comes to mind, there is a new electrochemical bio-sensing tool on the horizon.

Researchers have combined graphene with a tiny amount of gold to enhance the wonder material’s properties and develop a flexible skin patch to monitor blood glucose and automatically administer drugs as needed.

This from Extreme Tech:

[As] cool as a non-invasive blood-glucose monitor is, it’s nearly as revolutionary as what comes next: treatment. The patch is studded with “microneedles” that automatically cap themselves with a plug of tridecanoic acid. When high blood-glucose levels are detected, the patch heats a small heater on the needles which deforms the plug and allows the release of metformin, a common drug for treatment of type 2 diabetes. Cooling naturally restores the plug and stops drug release.

This development is a huge stepping stone in the transformation of graphene as a laboratory curiosity to a real product. While it has taken a while due to the questions of the new material’s intrinsic properties, researchers believe that graphene-based products could soon be hitting the market.
