With smart technology on the rise, researchers are looking for ways to develop smaller sensors that can help building the landscape of the internet of things. However, this could potentially demand huge sums of power in an era where people are working hard to conserve energy. A research team from Eindhoven University of Technology may have found a solution to this problem with the development of their new extra-small, wireless sensors that are powered by radio waves that make up its wireless network.

With a router nearby, the tiny sensors can pull the necessary energy to give them functionality. The sensor is just 2 millimeters and can communicate temperatures.

This from Gizmodo:

Aboard the chip, a small antenna captures energy from the signals transmitted by the router. Once it’s charged, the sensor quickly switches on, measures the temperature, and then transmits a small signal for the router to detect. The frequency of the transmitted signal relates to the measured temperature.

The researchers predict that the primary use for this sensor will be embedding the device within buildings to monitor conditions. Currently priced at 20 cents per sensor, researchers hope that with continued research, its potential could increase to detecting movement, light, and humidity.

The major issue right now lies in the fact that the sensor can only transmit its signal 2.5 centimeters. While the device is currently not practical, the team believes that its reach can grow to 16 feet with more research.

We are collecting stories from you about how having our peer-reviewed content from the ECS Digital Library has made a difference in your work.

Did you find content in our digital library that you would not have otherwise had access to that shaped your thinking and your research?

In 2014 ECS Digital Library started offering a portion of our published articles as open access. It was the start of our bold commitment to what we are calling — Free the Science. Through this mission-driven initiative, we are striving to open access to the entire ECS Digital Library–making all content from ECS journals freely available to all readers, while remaining free to publish for authors.

We caught a glimpse of the Free the Science ultimate vision during Open Access Week in October 2015: We made 100% of the content in the ECS Digital Library completely free to access for seven straight days and saw a 51% increase in the Journal of the Electrochemical Society usage compared to the same week in 2014.

We want to tell your story. Or maybe you know someone who our open access research has helped. Please contact me at Rob.Gerth@electrochem.org.

The Earth is getting warmer and greenhouse gas emissions are on the rise. With carbon dioxide levels at their highest in 650,000 years, scientists across the global are grappling with the question of how to stop global warming.

For many, alternative energy sources are the answer. While the implementation of this technology is crucial for the development of a carbon-free society, flipping the grid is easier said than done. The U.S. alone is highly dependent on fossil fuels, which emit high level of greenhouse gases. Additionally, transitioning the grid to 100 percent renewables would not fully solve the issue. Emissions will still exist in the atmosphere, with warming happening right now.

“When people emerge from poverty and move toward prosperity, they consume more energy,” said Adam Heller in a recent plenary lecture.

The Need for a Solution

Currently, 13 percent of carbon dioxide emissions stem from two industries: steel and cement. According to Heller, these industry are directly correlated to global wealth—what he deems the driving force of acceleration in climate change. To put that in perspective, the solar energy technology that is currently in place in the U.S. saves only 0.3 percent through the use of solar energy, according to Heller. With carbon dioxide emissions constantly accelerating, increasing by 2 percent every year, scientists are looking for solutions to this pressing issue.

“This will lead to a catastrophe,” Heller said. “The question is, what do we do about this catastrophe?”

For Heller and other scientists, part of the answer lies in solar geoengineering (SGE).

“We need to learn something about geoengineering,” Heller said. “We need to learn something about reflecting light from the sun through aerosols in the atmosphere.”

What does Doublemint gum have to do with biomedical research? Apparently, a lot more than would be expected.

A combined research effort from the University of Manitoba and the Manitoba Children’s Hospital has recently created a stretchy, highly sensitive biosensor using chewed gum and carbon nanotubes.

After the gum in chewed for about 30 minutes, it is then cleaned with ethanol and laced with carbon nanotubes. The biosensor has the potential to monitor berating patterns and blood flow.

Even more impressive, the cost for the sensor come in under $3. Researchers believe the cheap, highly flexible biosensor could aid in a multitude of health care applications.

In light of U.N. Climate Talks in Paris and the crippling air pollution levels in China, Bill Nye continuing the good fight against climate change with his latest pitch for a solution against the catastrophic force.

His possible solution? Bubbles.

Through a simple experiment, Nye explores the possibility of purposely inducing bubbles to potentially help satisfy water and sanitation demands as well as reflect light into space—helping control the global temperature.

In the full interview with Yahoo! News Live, Nye also discusses a carbon fee, the real threats of climate change, and “climate deniers.” Check out the full video.

A new form of carbon that has unprecedented strength and magnetism properties is making its mark in the world of materials science.

Researchers from North Carolina State University have recently developed a new phase of carbon called Q-carbon—an extraordinarily strong material that differs from carbon’s other two solid forms.

The first solid phase of carbon is graphite. Graphite is composed by lining up carbon atoms to form thin sheets, which results in a thin and flaky material. The other phase of carbon, diamond, occurs when carbon atoms form a rigid crystal lattice.

Third Phase of Carbon

“We’ve now created a third solid phase of carbon,” says Jay Narayan, lead author of the research. “The only place it may be found in the natural world would be possibly in the core of some planets.”

Q-carbon differs from both existing phases of carbon, with unique characteristics that researchers did not even think were possible prior to its development, such as its magnetic and glowing qualities. To fully understand its novel qualities, it’s essential to understand how Q-carbon was developed.
