Researchers from the University of Sydney have recently published their findings that quantum dots made of graphene can improve bio-imaging and LEDs.

The study was published in the journal Nanoscale, where the scientists detailed how activating graphene quantum dots produced a dot that would shine nearly five times bright than the conventional equivalent.

Essentially, the dots are nano-sized semiconductors, which are fluorescent due to their surface properties. However, this study introduces the utilization of graphene in the quantum dot, which produces an extra-bright dot that has the potential to help medicine.

Teams of scientists from around the world have been working on a way to produce spray-on solar cells for some time now. Recently, a team from the University of Toronto Faculty of Applied Science & Engineering has moved to the forefront of the race due to their latest breakthrough involving a new method for spraying solar cells onto flexible surfaces.

The prototype applies colloidal quantum dots via spray. These dots are a type of nanotechnology material that are light-sensitive.

This from Gizmag:

In such spray on solar cells, quantum dots would act as the absorbing photovoltaic material. Because they have a band gap that can be tuned by altering the size of their nanoparticles, they can be made to soak up different parts of the solar spectrum. This could prove particularly valuable if they were to be used in multi-junction solar cells, where dots small and large could sit alongside each other to widen the cells’ energy harvesting potential.

A recently conducted experiment may give us a better understanding of how the Earth possibly began.

Scientists took to the lab with a powerful 500-foot laser to re-create what might have been the original spark of life on Earth.

This from Associated Press:

The researchers zapped clay and a chemical soup with the laser to simulate the energy of a speeding asteroid smashing into the planet. They ended up creating what can be considered crucial pieces of the building blocks of life.

The Lowline is not just a design project. It’s not just an example of innovative technology. It’s not just an effort to revitalize a community. The Lowline is an example of how science and drive can improve and transform the landscape of modern cities.

If you haven’t yet heard of Lowline, it will essentially be an underground park powered by innovative solar technology located in the 116-year-old abandoned Williamsburg Bridge Trolley Terminal in the Lower East Side of Manhattan.

The technology is designed by James Ramsay of Raad Studio, who looks to overcome subterranean limitations with his underground oasis of plants and trees.

Since its launch, the Blu-ray disc has been promoted as the bigger, better, and more impressive way to view movies at home. But researchers from Northwestern University are now telling us that Blu-ray discs are good for more than just giving us a better home viewing experience.

An interdisciplinary team from the McCormick School of Engineering and Applied Science at Northwestern University has published research stating that Blu-ray discs can be used to improve the performance of solar cells.

A new chemical sponge out of the University of Nottingham has the potential to lessen the carbon footprint of the oil industry.

Professor Martin Schröder and Dr. Sihai Yang of the University of Nottingham led a multi-disciplinary team from various institutions, which resulted in the discovery of this novel chemical sponge that separates a number of important gases from mixtures generated during crude oil refinement.

Crude oil has many uses – from fueling cars and heating homes to creating polymers and other useful materials. However, the existing process for producing this fuel has not been as efficient as it could possibly be.

The ballistic test shows that graphene is excellent at both absorbing and spreading the energy of an impact.

We’ve been talking a lot about graphene – from its potential in energy storage to its ability to improve and revolutionize personal electronic devices, this material seems to be everywhere. Now, engineers out of the University of Massachusetts believe it could help save lives.

Engineers developed a mock-up of multilayered graphene body armor and tested it in a miniature shooting range. The results suggest that graphene may be able to absorb 10 times the amount of energy that its steel competitor can before failing.

While browsing through the vast array of Open Access articles that ECS hosts in its Digital Library, one title in particular caught our eye here at headquarters.

I mean, it is pretty hard to ignore an academic article titled “Wireless Communication by an Autonomous Self-Powered Cyborg Insect.”

The article, published in the Journal of The Electrochemical Society by researchers from Case Western Reserve University (one of the authors is ECS Board of Directors Senior VP Dan Scherson), details – to put it simply – how a cyborg cockroach can generate and transmit signals wirelessly.

Here at ECS, we love to talk about renewable resources – and we also like talking about poop. And with Britain’s first ‘poo-powered’ bus hitting the roads, we have a perfect excuse to talk about both.

GENeco has developed the new 40-seat Bio-Bus, which is powered by human waste. In technical terms, the bus runs on the biomethane gas that is produced at a sewage treatment works in Avonmouth.

According to BBC, the bus can travel up to 300 km – or 186 miles – on one tank of gas. One tank would be equivalent to the annual waste of five people. Further, the vehicle will emit up to 30 percent less carbon dioxide than conventional diesel vehicles.

More and more households are using LED light bulbs due to improved efficiency, reliability, and now a more affordable cost over their incandescent cousins. With droves of scientists researching in the area of LED and producing new developments, these bulbs are beginning to become the new norm.

Let’s take a look at the journey the LED bulb has gone though thus far.
