A new study shows remarkable parallels between hydrogen and graphene under extreme pressures.
The study was conducted by Carnegie’s Ivan Naumov and Russell Hemley, and can be found in the December issue of Accounts of Chemical Research.
Because of hydrogen’s simplicity and abundance, it has long been used as a testing ground for theories of the chemical bond. It is necessary to understand chemical bonding in extreme environments in order to expand our knowledge of a broad range of conditions found in the universe.
It has always been difficult for researchers to observe hydrogen’s behavior under very high pressure, until recently when teams observed the element at pressures of 2-to-3.5 million times the normal atmospheric pressure.
Under this pressure, it transforms into an unexpected structure that consists of layered sheets, rather than close-packed metal – which had been the prediction of scientists many years ago.

Gerischer’s immense contributions continue to leave an indelible mark, not only in electrochemistry, but also in physical chemistry and materials chemistry.
An article by Adam Heller, Dieter Kolb, and Krishnan Rajeshwar in the Fall 2010 issue of Interface.
Heinz Gerischer was born on March 31, 1919 in Wittenberg, Germany. He studied chemistry at the University of Leipzig between 1937 and 1944 with a two-year interruption because of military service. In 1942, he was expelled from the German Army because his mother was born Jewish; he was thus found “undeserving to have a part in the great victories of the German Army.” The war years were difficult for Gerischer and his mother committed suicide on the eve of her 65th birthday, in 1943. His only sister, Ruth (born in 1913), lived underground after escaping from a Gestapo prison and was subsequently killed in an air raid in 1944.
In Leipzig, Gerischer joined the group of Karl Friedrich Bonhoeffer, a member of a distinguished family, members of whom were persecuted and murdered because of opposition to Nazi ideology. Bonhoeffer descended from an illustrious chemical lineage of Wilhelm Ostwald (1853-1932) and Walther Hermann Nernst (1864-1941), and kindled Gerischer’s interest in electrochemistry, supervising his doctoral work on periodic (oscillating) reactions on electrode surfaces, completed in 1946. He followed Bonhoeffer to Berlin where his PhD supervisor had accepted the directorship of the Institute of Physical Chemistry at the Humboldt University, and also became the department head at the Kaiser Wilhelm Institute for Physical Chemistry in Berlin-Dahlem (later the Fritz Haber Institute). Gerischer himself was appointed as an “Assistent.” Many years later, Gerischer would return to this distinguished institution as its director. With the Berlin Blockade and the prevailing economic conditions the post-war research was carried out under extremely difficult conditions.

Improvements in solar power are being developed all around the world, with scientist and researchers continuously attempting to apply electrochemistry and other sciences to solar cells in order to improve efficiency. Recently, the National Renewable Energy Laboratory (NREL) has reported one of the highest photovoltaic cell efficiencies achieved across all types of solar cells.
Researchers at the NREL have demonstrated a 45.7 percent conversion efficiency for a four-junction solar cell at 234 suns concentration.
Congratulations to all graduating ECS student members!

Hard-work and perseverance have paid off for The Electrochemical Society’s Telpriore “Greg” Tucker. From chemist, to mentor, to entrepreneur—the Arizona State University doctoral graduate aims to make an impact in renewable energy and transportation.
With his new degree in hand, Tucker plans to revisit his business plans for The Southwest Battery Bike Company, which focuses on developing electric bicycles that can provide a more affordable and greener source of transportation.
“I’ve always had an interest in transportation and how to make it more affordable and sustainable for the public,” Tucker says. “Since my degree focuses on batteries for renewable energy purposes, I began to see a lot of applications from my research. Some of the best jobs can spring from your hobby or projects that you enjoy doing.”

Request for Proposals
The Electrochemical Society with Toyota North America
Announces the ECS Toyota Young Investigator Fellowship
for Projects in Green Energy Technology
Proposal Submission Deadline: January 31, 2015
ECS, in partnership with the Toyota Research Institute of North American (TRINA), a division of Toyota Motor Engineering & Manufacturing North America, Inc. (TEMA), is requesting proposals from young professors and scholars pursuing innovative electrochemical research in green energy technology.
Global development of industry and technology in the 20th century, increased production of vehicles and the growing population have resulted in massive consumption of fossil fuels. Today, the automotive industry faces three challenges regarding environmental and energy issues: (1) finding a viable alternative energy source as a replacement for oil, (2) reducing CO2 emissions and (3) preventing air pollution. Although the demand for oil alternatives—such as natural gas, electricity and hydrogen—may grow, each alternative energy source has its disadvantages. Currently, oil remains the main source of automotive fuel; however, further research and development of alternative energies may bring change.
