In a paper to be published in the forthcoming issue in NANO, researchers from the National Institute of Technology, India, have synthesized blue-green-orange photoemissive sulfur and nitrogen co-doped graphene quantum dots (SNGQDs) using hydrothermal method. These GQDs showed strong UV-visible photoabsorption and excitation dependent photoemission which have low-cost, eco-friendly solar cell application.

Quantum dots, which have potential uses in medical imaging and solar cells, could be made with help from the polyphenols found in tea leaves.

The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts—two petawatts—for an incredibly short duration, approximately a trillionth of a second or one picosecond.

Values this large are difficult to grasp, but we can think of it as a billion times more powerful than a typical stadium floodlight or as the overall power of all of the sun’s solar energy that falls on London. Imagine focusing all that solar power onto a surface as wide as a human hair for the duration of a trillionth of a second: that’s essentially the LFEX laser.

LFEX is only one of a series of ultra-high power lasers that are being built across the world, ranging from the gigantic 192-beam National Ignition Facility in California, to the CoReLS laser in South Korea, and the Vulcan laser at the Rutherford Appleton Laboratory outside Oxford, UK, to mention but a few.

If I were to make a prediction, I’d think there’s a good chance that it is not batteries. But capacitors.”

Today he may be making good on his prediction. The electric vehicle manufacturer confirmed that it has acquired a small San Diego lab that owns ultracapacitor patents and technology.

Maxwell Technologies provides dry electrode manufacturing technology that can be used to make to make batteries that power electric vehicles and renewable energy systems. The company announced that in an all-stock transaction it will merge and become a wholly owned by a subsidiary of Tesla.

Interesting concept.

Architectural students working with the European Space Agency (ESA) have created a new concept for a sustainable lunar habitat.

The ESA’s astronaut center in Cologne, Germany, partners with universities and research institutions to study moon-related concepts in preparation for future missions. Angelus Chrysovalantis Alfatzis is one of the researchers who has contributed to the development of a promising concept for a moon base, according to a statement from ESA.

A team of researchers from Michigan State University managed to develop a fully transparent solar panels – a breakthrough that could lead to countless applications in architecture, as well as other fields such as mobile electronics or the automotive industry. Previous attempts to create such a device have been made, but results were never satisfying enough, with low efficiency and poor material quality.

The new design stores heat generated by excess electricity from solar or wind power in large tanks of white-hot molten silicon, and then converts the light from the glowing metal back into electricity when it’s needed. The researchers estimate that such a system would be much more affordable than lithium-ion batteries, which have been proposed as a viable, though expensive, method to store renewable energy. They also estimate that the system would cost about half as much as pumped hydroelectric storage—the cheapest form of grid-scale energy storage so far.

Delivering solar- or wind-generated power on demand, the system, which uses molten silicon, should be cheaper than other leading options.

Scientists have characterized the quantum behavior of buckminsterfullerene molecules, also known as buckyballs, with the hope of perhaps one day turning them into miniature quantum computers.

Buckyballs are the Nobel Prize-winning molecules that consist of sixty carbon atoms arranged in a closed, soccer ball-shape. Their peculiar structure bestows them with strange observable quantum properties, and has given them uses in solar panels and even medicine. But a team of scientists from JILA, a research institute run by the National Institute of Standards and Technology and the University of Colorado, has made measurements in preparation for exploiting buckyballs’ quantum properties in even stranger ways.
