Oil spills have had an extensive history of disrupting the environment, killing ecosystems, and displacing families. Impacts of massive oil spills are still felt in many parts of the world, including the undersea spill at the BP oil rig in the Gulf of Mexico that dumped an approximate 39 million gallons of oil into the gulf.

But what if these devastating oil spills could be easily cleaned up with a piece of fabric rooted in electrochemistry?

That may be a reality soon thanks to researchers at Queensland University of Technology (QUT). According to a release, the QUT researchers have developed a multipurpose fabric covered with semi-conducting nanostructures that can both mop up oil and degrade organic matter when exposed to light.

The fabric, which repels water and attracts oil, has already has promising preliminary results. In the early stages of research, the scientists have already been able to mop up crude oil from the surface of both fresh and salt water.

Researchers from The Scripps Research Institute (TSRI) have developed a new technique that has the potential to boost a traditional chemical reaction, opening doors for new developments in pharmaceuticals and other industries.

The researchers developed an easier, cheaper, and greener way to preform allylic oxidation – a process that typically employs toxic or expensive reagents and has previously been difficult, if not impossible, to implement on a large scale. By using the power of old-fashioned electrochemistry, the TSRI researchers discovered a way to make the process scalable through the use of safe chemicals.

“Turns out one of the best reagents you can buy is sitting in your wall socket,” said principal investigator Phil Baran. “The scope of the reaction is just phenomenal. It’s super easy to do, and the overall improvement in environmental sustainability is dramatic.”

In early December of 2015, Sen. Jeff Flake (R-Ariz.) penned what he deemed the “Wastebook” – a report detailing what the senator believes to be wasteful federal spending, specifically targeted at research dollars.

The report took aim at research the fiscal conservative considered a waste of federal cash, including projects he summed up as a “shrimp fight club,” a study of cows in China, an exploration of why obese women can’t get dates, and a look at shrimp on a treadmill.

Earlier this month, those very same scientists that Flake criticized and reduced their research to mere waste took to Pennsylvania Avenue to reinforce the legitimacy of their work.

Researchers respond

“I am rock solid about my research. I know it is very good,” said Sheila Patek, an associate professor of biology at Duke University who led the so-called shrimp fight club study. “But this ‘Wastebook’ targeted a short paper that was the first paper in my young graduate student’s career. He is from a long line of firefighters. His father, his uncle, his grandfather. There aren’t any other scientists in his family. They are very proud of him. He is extremely civic-minded. I don’t think I’ve had anyone in my lab like that. And this has been crushing for him.”

AA Battery CarThere may soon be a shift in the transportation sector, where traditional fossil fuel-powered vehicles become a thing of the past and electric vehicles start on their rise to dominance.

In fact, we may be seeing that shift already. Last year, battery prices fell 35 percent, which contributed to the 60 percent increase in sales of electric vehicles. If that growth continues along the same path, electric vehicles have the potential to displace oil demand of two million barrels a day as early as 2023.

The key technology at the heart of these vehicles is energy storage. Whether it be the lithium-ion, lithium-air, or fuel cells – electric vehicles depend on affordable, highly efficient electrochemical energy storage to operate.

But what if the future of these vehicles depend on a different type of energy technology?

Saturday Night Live recently made a play on the future of electric vehicles by imagining a world where cars didn’t run off of a singular, efficient battery — but rather tons of AA batteries.

Check out what a car powered entirely out of AA batteries could look like.

Open access continues to gain momentum globally

openaccessroundGlobally, open access can help create a world where everyone from the student in Atlanta to a researcher in Haiti can freely read the scientific papers they need to make a discovery; where scientific breakthroughs in energy conversion, sensors, or nanotechnology are unimpeded by fees to access or publish research.

The global open access effort aims to break down barriers and make online scholarly information free to everyone, promote the global exchange of scientific discoveries, and open the door to the faster development of practical applications that could address some of the world’s most pressing issues.

Accelerating discovery in Africa

Recently, Senegal started building this framework for African countries that often lack access to scientific and education information. During April’s Council for the Development of Social Science Research in Africa, representatives from the west-African country decided to begin the process to ensure the establishment of a national open access policy, making them the first African country to establish such a policy.

Leaders hope this new policy will encourage the creation of open platforms free and accessible for all researchers, innovators, teachers, students, media professionals, and the public and will encourage collaboration, production, dissemination, and knowledge economies.

HIV and hepatitis C are among the leading causes of worldwide death. According to amfAR, an organization dedicated to eradicating the spread of HIV/AIDS through innovative research, nearly 37 million people are currently living with HIV. Of those 37 million, one third become co-infected with hepatitis C.

The threat of HIV and hepatitis C

The regions hit the hardest by this co-infection tend to be developing parts of the world, such as sub-Saharan Africa and Central and East Asia.

While these developing regions have measures to diagnosis HIV and hepatitis C, the rapid point-of-care tests used are typically unaffordable or unreliable.

An electrochemical solution

A group from McGill University is looking to change that with a recently developed, paper-based electrochemical platform with multiplexing and telemedicine capabilities that may enable low-cost, point-of-care diagnosis for HIV and hepatitis C co-infections within serum samples.

With the increasing popularity of solar power and ongoing dialogue about the effects of climate changes comes inevitable discussions about the viability of renewable energy. While efficiency levels have grown tremendously over the years, many still worry about the feasibility of solar panels during inclement weather when the sun is not shining its brightest.

To address that issue, more attention has been focused on energy storage. However, a group of Chinese scientists are turning to the solar panels themselves to answer some of these questions.

In a recently published paper, scientist detailed a new way for solar panels to produce electricity from rain water. The way it works is pretty simple: researchers apply a thin layer of graphene to the bottom of the solar panel; when it rains, you simply flip the panel and allow the positively charged ions from the rain drops to interact with the graphene and produce electricity.

“Although great achievements have been made since the discovery of various solar cells, there is still a remaining problem that the currently known solar cells can only be excited by sunlight on sunny days,” wrote the researchers in the paper.

Carbyne

The material Carbyne hit the benchtop years ago. Scientists were able to calculate the properties of this exotic material, but not able to stabilize it. Carbyne promised to be stronger and stiffer than any other material known to man, but the question of how to synthesize it remained.

Now, researchers from the University of Vienna in Austria were able to do just that. The researchers took the highly reactive, one-dimensional chain of carbon atoms and synthesized it by wrapping it in a double-walled tube of graphene that provided a protective casing, allowing the material to remain intact.

This from Gizmodo:

The record for stringing together carbon atoms like this in the past had been 100 in a row; now, the team can put 6,400 atoms together, and have them remain in a chain for as long as they want. That is, of course, as long as they sit inside the carbon Thermos. It remains to be seen how useful Carbyne will be whilst wrapped up, but for now it’s the best that researchers can achieve.

Read the full article.

While not much is known about Carbyne, the material is believed to be stronger than both graphene and diamonds, and twice the stiffness of any known material. Maybe (just maybe) this could bring us one step closer to space elevators.

Artificial limbs have experience tremendous evolution in their long history. Throughout history, we’ve gone from the peg leg of the Dark Ages to technologically advanced modern day prosthesis that mimic the function of a natural limb. However, most prosthesis still lack a sense of touch.

Zhenan Bao, past ECS member and chemical engineer at Stanford University, is at the forefront of the research looking to change that.

(MORE: Read Bao’s past meeting abstracts in the ECS Digital Library for free.)

Recently on NPR’s All Things Considered, Bao described her work in developing a plastic artificial skin that can essentially do all the things organic skin can do, including sensing and self-healing.


The self-healing plastic Bao uses mimics the electrical properties of silicon and contains a nano-scale pressure sensor. The sensor is then connected to electrical circuits that connect to the brain, transmitting the pressure to the brain to analyze as feeling.

Additionally, the skin is set to be powered by polymers that can turn light into electricity.

While there is still much work to be done, Bao and her colleagues believe that this product could help people who have lost their limbs regain their sense of touch.
