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.

“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.

Nikola Tesla is undoubtedly one of the most recognizable scientists in history, unfortunately much of his groundbreaking research lived in the shadows for the majority of his life. His pioneering contributions to science included alternating current, hydroelectricity, cryogenic engineering, the remote control, neon lighting, and wireless communication just to name a few.

While Tesla may have died around 30 years before the first call made made via a wireless cellphone, his advances in science helped make that reality achievable.

In an effort to offer the man at the core of wireless communication, a new statue has been erected in Tesla’s likeness in Silicon Valley that is equipped with free Wi-Fi.

The statue is the brainchild of Dorrian Porter, and entrepreneur that finds likeness with Tesla in that they were both immigrant that found scientific success in the U.S.

“This unique project… is also intended to inspire the entrepreneurs who come to the Silicon Valley to think big and selflessly—as Tesla did,” says Porter. “The free exchange of information and affordable access to sustainable energy have the potential to solve the critical issues of poverty and education, and inspire peace.”

President Obama has pushed through the first installment of a pledged $3 billion from the cabinet to help poor countries fight climate change.

The first chunk of change went to the Green Climate Fund, an international body created to assist developing countries adapt to and mitigate climate change.

The effects of climate change often hit the world’s poor the hardest. Millions of the poorest families around the world are farmers, suffering from the devastating effects of harmful emissions affecting local climates. This could sink those families even deeper into poverty, yet they are typically the ones least at fault for the rising levels of emissions such as carbon dioxide.

The $500 million is part of President Obama’s Clean Power Plan, which is aimed at cutting U.S. carbon emissions in order to fight climate change. The first transaction shows that the cabinet is committed to delivering on its pledge made at the United Nations’ climate change conference in Paris in late 2014.

“The United States provided a $500 million grant to the Green Climate Fund,” a State Department official said. “This grant is the first step toward meeting the president’s commitment of $3 billion to the GCF, and shows that the United States stands squarely behind our international climate commitments.”

Not only does this payment help enact measures to fight climate change, President Obama also hopes it will act as a signal to the national and international community after the supreme court block a major piece of the cabinet’s climate plan last month.

CO2 to CO

An important innovation is the optimized interface between gas, fluid and copper particles, allowing the very efficient supply of CO2 and removal of the product, CO.

In an effort to convert carbon dioxide into carbon dioxide, researchers have developed an electrode in the form of a hollow porous coper fiber that completes this transformation at an extremely efficient level.

The researchers, including ECS member Marc T.M. Koper, believe that this development could give the industrial industry an edge, where it would be extremely beneficial for chemical processes that require gas conversion.

(MORE: Read additional research by Koper.)

The process is not confined to the conversion of carbon dioxide to carbon monoxide, however. Because the manufacturing method is suited for other fibers, it could also be applied to the conversion of oxygen in a fuel cell or hydrogen conversion in the electrochemical production of ammonia.

While the principal idea behind the process is straightforward, the efficiency and selectivity of the reaction is the surprising factor.

There is no doubt that women have made an immense impact on the sciences. From Marie Curie to Esther Takeuchi, women have made outstanding contributions to innovation, research, and technology.

In honor of International Women’s Day and Women’s History Month, we’re celebrating by (briefly) highlighting a few women who have changed STEM.

Marie Curie

A list of pioneering women in STEM would be incomplete if it did not include the extraordinary Marie Curie. Her inspiring story and discovery or radium helped pave the way to inspire many future women in STEM. Curie was the first woman ever to win a Nobel Prize, the first person and only woman to win twice, and the only person to win in multiple sciences.

Irene Joliot-Curie

Continuing the work of her mother Marie Curie, Irene Joliot-Curie was awarded the Nobel Prize in 1935 for the synthesis of new radioactive elements. Her work included the study of natural and artificial radioactivity, transmutation of elements, and nuclear physics. Joliot-Curie’s work lead to research by German physicist that eventually resulted in the discovery of nuclear fission.

Lili Deligianni

Lili Deligianni’s innovative work in chemical engineering has led to cutting-edge developments in chip technology and thin film solar cells. She has been with ECS for many years, currently serving as the Society’s secretary. Her current research interests in the development of materials for low power on-chip converters and thin film solar cells are game changing technologies that could have applications in solar panel sand electric cars.
