Scientists Achieve Million-Fold Energy Enhancement in Diamond Optical Antennas

Posted by in categories: energy, engineering, physics

Theory has become practice as new work from the University of Chicago Pritzker School of Molecular Engineering taps diamond defects’ remarkable ability to concentrate optical energy.

Researchers have developed atomic antennas using germanium vacancy centers in diamonds, achieving a million-fold optical energy enhancement. This advancement allows the study of fundamental physics and opens new research avenues. The collaboration between theoretical and experimental teams was essential to this breakthrough.

Atomic antennas: harnessing light for powerful signals.

‘Once-in-a-lifetime’ explosion will bring a new star to the night sky

Posted by in categories: energy, space

Astronomers are expecting a “new star” to appear in the night sky anytime between now and September in a celestial event that has been years in the making, according to NASA.

“It’s a once-in-a-lifetime event that will create a lot of new astronomers out there, giving young people a cosmic event they can observe for themselves, ask their own questions, and collect their own data,” said Dr. Rebekah Hounsell, an assistant research scientist specializing in nova events at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement. “It’ll fuel the next generation of scientists.”

The expected brightening event, known as a nova, will occur in the Milky Way’s Corona Borealis, or Northern Crown constellation, which is located between the Boötes and Hercules constellations.

Scientists make and test efficient water-splitting catalyst predicted by theory

Posted by in categories: chemistry, energy, sustainability

Hydrogen (H2) is a promising fuel for reducing greenhouse gases, especially if produced by using renewable energy to split water molecules (H2O). But as simple as it may seem to break water into hydrogen and oxygen, the chemistry is complex.

A major US offshore wind hub just broke ground in New York City

Posted by in categories: energy, futurism

Today, the South Brooklyn Marine Terminal (SBMT) broke ground, kicking off the transformation of the historic port into an East Coast offshore wind hub.

SBMT will support Norwegian energy giant Equinor’s first US offshore wind project, Empire Wind 1. Brooklyn’s new offshore wind hub is designed to be a central, scalable hub for the expanding East Coast offshore wind market, and as a port for future offshore wind developments.

When the terminal is complete, it will be one of the largest dedicated offshore wind hubs in the US.

New energy company hopes to boost Texas’ fragile power grid

Posted by in category: energy

Base Power is led by Zach Dell — the son of Dell Technologies founder and CEO Michael Dell — and Justin Lopas.

The company provides a distributed battery storage to homeowners, which allows them to have a “reliable and affordable” backup source if there is an outage. The battery itself, according to Lopas, allows the grid to be more efficient.

Surface Bubbles Could Have Evolved into Earth’s First Cells

Posted by in categories: energy, materials

(Inside Science) – Primitive “protocells” like those that evolved into the first living cells can form in bubbles on mineral surfaces that were plentiful on the early Earth, according to new research.

The researchers created artificial protocells that they believe may be similar to the protocells that may have formed on Earth about 3.8 billion years ago. The artificial protocells can absorb other small molecules by forming a barrier membrane around them — behavior that is strikingly like that of modern living cells when they absorb cellular fuel and other essential materials while blocking off harmful substances.

And the artificial protocells also exhibit a primitive form of “division,” where the outer membrane of a protocell ruptures and leaves behind several “daughter” protocells with the same capabilities.
