Access to clean drinking water is something many take for granted. Crises like that of Flint, MI illuminate the fragility of our water infrastructure and how quickly access can be taken away. Even now, hundreds of millions of people around the world still lack access to adequate water.

Gaining access

But it’s not all negative. In the past 25 years, 2.6 billion people worldwide gained access to clean drinking water. This initiative stemmed from part of the Millennium Development Goals set by the United Nations in 1990, attempting to cut the number of global citizens without access to clean drinking water in half. While this goal was achieved in 2010, there are still about 663 million without proper water and sanitation.

The divide

So who doesn’t have clean drinking water? Overall, urban areas tend to have greater access due to improved water infrastructure systems set in place. Access in rural areas has improved over the years, but people in these areas are still hit the hardest.

The major divide is most visible when analyzing the numbers by regions. Africa, China, and India are among the hardest hit, making up the majority of the 663 million citizens without access to water.

It doesn’t matter how green you thumb is, there will always be fruits and vegetables in your garden that just don’t quite make it. The same concept goes for commercial farms, where farmers accumulate tons of fruit and vegetable waste every year.

In fact, the state of Florida alone produces an estimated 369,000 tons of waste from tomatoes each year. But what if you could turn that waste into electricity?

That’s exactly what one team comprised of researchers from South Dakota School of Mines & Technology, Princeton University, and Florida Gulf Coast University are doing.

In order to produce the electricity, the team developed a microbial electrochemical cell that can use tomato waste to generate electric current.

“We have found that spoiled and damaged tomatoes left over from harvest can be a particularly powerful source of energy when used in a biological or microbial electrochemical cell,” says Namita Shrestha, a graduate student working on the project.

This from Tree Hugger:

The bacteria in the fuel cell trigger an oxidation process that releases electrons which are captured by the fuel cell and become a source of electricity. The tomatoes have proven to be a potent energy source. The natural lycopene in the tomatoes acts as a mediator to encourage electricity generation and the researchers say that while waste material usually performs poorly compared to pure chemicals in fuel cells, the waste tomatoes perform just as well or better.

While their first trial resulted in just 0.3 watts of electricity per 10 milligrams of tomato waste, the researchers believe that more trials will result in improved electricity generation.

In December of 1992, the premier issue of Interface was published with a cover celebrating Rudolph Marcus’s winning of the Nobel Prize that year. But did you know that prior to that first issue of Interface, ECS published its members magazine prototype named the Quarterly? It was published in January 1992 and its cover showed a porous silicon sample luminescing in the visible when irradiated by an argon ion laser.

In that prototype issue, then ECS president Larry Faulkner said in his Letter from the President, “The periodic self-analysis of the Society’s agenda and structure is an extremely important part of our life. Without it, we will fail to adapt effectively to a changing environment, so the work is essential in the strictest sense.” Still good advice today.

Now, over 90 issues later, we’re celebrating the 25th anniversary of Interface. Throughout the issues this year, readers will be treated to special excerpts looking back at some of the top moments in the magazine’s history.

We’re inviting readers to share their thoughts about Interface, in particular how the magazine may have impacted your research or career. Send your thoughts to Interface@electrochem.org.

When we think of carbon and the environment, our minds often develop a negative association between the two in light of things such as greenhouse gases and climate change. But what if carbon is the answer to clean energy?

A team of researchers at Griffith University is looking toward carbon to lead the way in the clean energy revolution. Their latest research showed that carbon could be used to produce hydrogen from water. This could offer a potential replacement for the costly platinum materials currently used.

“Hydrogen production through an electrochemical process is at the heart of key renewable energy technologies including water splitting and hydrogen fuel cells,” says Professor Xiangdong Yao, leader of the research group. “We have now developed this carbon-based catalyst, which only contains a very small amount of nickel and can completely replace the platinum for efficient and cost-effective hydrogen production from water.”

This from Griffith University:

Proponents of a hydrogen economy advocate hydrogen as a potential fuel for motive power including cars and boats and on-board auxiliary power, stationary power generation (e.g., for the energy needs of buildings), and as an energy storage medium (e.g., for interconversion from excess electric power generated off-peak).

The researchers also believe that these findings could open the door for new development in large-scale water electrolysis.

Wrinkles and crumples, introduced by placing graphene on shrinky polymers, can enhance graphene’s properties.

By now we’ve heard about the seemingly endless possibilities for the wonder material graphene. The engineers at Brown University are looking to make those possibilities even more appealing through a process that could make the nanomaterial both water repellant and enhance its electrochemical properties.

The research team is looking to improve upon the already impressive graphene by wrinkling and crumpling sheets of the material by placing it on shrink polymers to enhance its properties, potentially leading to new breakthroughs in batteries and fuel cells.

This from Brown University:

This new research builds on previous work done by Robert Hurt and Ian Wong, from Brown’s School of Engineering. The team had previously showed that by introducing wrinkles into graphene, they could make substrates for culturing cells that were more similar to the complex environments in which cells grow in the body. For this latest work, the researchers led by Po-Yen Chen, a Hibbit postdoctoral fellow, wanted to build more complex architectures incorporating both wrinkles and crumples.

Crumpling the graphene makes it superhydrophobic, a property that could be used to develop self-cleaning surfaces. Additionally, the enhanced electrochemical properties could be used in next-generation energy storage and production.

“You don’t need a new material to do it,” said Po-Yen Chen, co-author of the study. “You just need to crumple the graphene.”

Businessman, author, and one of the foremost minds behind the development of the semiconductor, Andy Grove, passed away on Monday at the age of 79.

Technological giant

During his three decades with Intel, Grove helped transform the chip-making colossus into the world’s largest manufacturer of semiconductors. He grew with the company as it obtained more and more success, acting as Intel’s president in 1979 and becoming CEO in 1987.

“We are deeply saddened by the passing of former Intel Chairman and CEO Andy Grove,” said current Intel CEO Brian Krzanich in a news release. “Andy made the impossible happen, time and again, and inspired generations of technologists, entrepreneurs, and business leaders.”

Many considered Grove as one of the giants in the world of technology, leaving his mark on everything from memory chips to the digital revolution at large. Without Grove’s contributions to the development of the semiconductor, much of modern life would be very different. Items such as handheld electronics, LED displays, and even solar cells would not exist if not for the semiconductor.

Grove’s influence on ECS

Here at ECS, Grove’s contributions to technology have helped shape some of our divisions and topical interest areas. In 2013, the Society established the Bruce Deal & Andy Grove Young Author Award to recognize the best paper published in the ECS Journal of Solid State Science and Technology (JSS) by a young author. The award was named in Deal, another Fairchild employee, and Grove’s honor for a seminal paper that was published in the Journal of The Electrochemical Society (JES) describing the Deal-Grove model, which is used to analyze thermal oxidation of silicon in semiconductor device fabrication and has had a lasting influence on the semiconductor technology industry.
