From solar cells to fuel cells to body armor, graphene has more potential applications than one could briefly summarize. Now, this wonder material is entering into a new realm of possibility.

According to new research from the University of Belgrade in Serbia, graphene has amazing sound detection qualities. Because of this, the researchers have developed the world’s first graphene-based condenser microphone. At about 32 times the strength of some of today’s best microphones, the graphene-based device has the ability to detect a range of audible frequencies. Further, the researchers believe that with a little more tweaking, it will be able to pick up sound that is well beyond the range of human hearing.

This from Gizmodo:

The researchers used a chemical vapor deposition process to “grow” sheets of graphene on a nickel foil substrate. They then etched the nickel away and placed the remaining graphene sheet (about 60 layers thick) in a commercial microphone casing. There, it acts as a vibrating membrane, converting sound to electric current.

With energy demands increasing every day, researchers are looking toward the next generation of energy storage technology. While society has depended on the lithium ion battery for these needs for some time, the rarity and expense of the materials needed to produce the battery is beginning to conflict with large-scale storage needs.

To combat this issue, a French team comprised of researchers primarily from CNRS and CEA is making gains in the field of electrochemical energy storage with their new development of an alternative technology for lithium ion batteries in specific sectors.

Beyond Lithium

Instead of the rare and expensive lithium, these researchers are focusing on the use of sodium ions—a more cost efficient and abundant materials. With efficiently levels comparable to that of lithium, many commercial sectors are showing an increasing interest for sodium’s potential in storing renewable energy.

While this development takes the use of sodium to a new level, the idea has been around since the 1980s. However, sodium never took off as the primary battery building material due to low energy densities and short life cycles. It was then that researchers chose to power electronics with lithium for higher efficiency levels.

The effort to harvest atmospheric carbons and transform the greenhouse gases into renewable fuels has taken one step closer to practicality due to new research out of Monash University.

Through the novel combination of cheap materials to develop an energy efficient catalyst, the researchers believe they could electrochemically reduce carbon dioxide into syngas. This produced syngas would be comprised of a combination of carbon monoxide and hydrogen—the elements widely used as the starting point to produce sustainable fuels and materials.

“Our research found that a combination of cheap materials—Molybdenum Sulphide catalytic nano-particles with a conductive layer of graphene and a well-known polymer called polyethylenimine acted together to create this energy efficient catalyst. Each component in the catalyst played a specific role in the reaction and it was only when the three were combined that the energy efficiency of the process was realized,” said Jie Zhang, lead author of the study.

In a practical effort to address climate change, researchers are looking at the possibility to capture harmful greenhouse gasses and transforming them into something useful for society. Recently, researchers from the University of South Carolina started exploring this topic, opening the door for more research in green fuels produced by carbon. Now, a team from the University of South Australia is taking that concept and applying nanoporous carbon nitride to help solve global warming.

With carbon dioxide levels at their highest in 650,000 years, scientists are developing innovative ways to help contain the greenhouse gas. The team at the University of South Australia, led by Ajayan Vinu, is working to capture and convert carbon dioxide molecules with the help of nanoporous materials.

“Their interesting properties—a semiconducting framework structure and ordered pores—make them exciting candidates for the capture and conversion of [carbon dioxide] molecules into methanol which can then be used as a source of green energy with the help of sunlight and water,” Vinu said.

When viruses emerge—spreading in a rapid and extensive way—researchers must scramble to create life-saving vaccines. At Brigham Young University, researchers are working to speed up that process.

A team of chemical engineers has devised a way to create machinery for vaccine production en masse, freeze drying the produced vaccines and stockpiling them for future use. This development could aid in relief efforts when new viruses hit populations, allowing researchers to rapidly produce vaccines.

“You could just pull it off the shelf and make it,” says Brad Bundy, senior author of the study. “We could make the vaccine and be ready for distribution in a day.”

This from Brigham Young University:

Bundy’s idea is a new angle on the emerging method of ‘cell-free protein synthesis,’ a process that combines DNA to make proteins needed for drugs (instead of growing protein in a cell). His lab is creating a system where the majority of the work is done beforehand so vaccine kits can be ready to go and be activated at the drop of a dime.

Researchers from MIT have unveiled new opportunities in diagnostics through the development of an ingestible sensor with the ability to continuously monitor vital signs. The device, which measures heart rate and breathing from within the gastrointestinal track, has the potential to offer beneficial assessment of trauma patients, soldiers in battle, and those with chronic illness.

“Through characterization of the acoustic wave, recorded from different parts of the GI tract, we found that we could measure both heart rate and respiratory rate with good accuracy,” says Giovanni Traverso, one of the lead authors of the study.

The development of pulse sensors such as this are beginning to outpace the traditional stethoscope. However, the pulse sensors that currently exist wrest on the patient’s skin, which is problematic for those with skin sensitivity such as burn victims.
