Researchers witness nanoscale water formation in real time

Posted by in category: nanotechnology

“It’s a known phenomenon, but it was never fully understood,” said Yukun Liu, the study’s first author and a Ph.D. candidate in Dravid’s laboratory. “Because you really need to be able to combine the direct visualization of water generation and the structure analysis at the atomic scale in order to figure out what’s happening with the reaction and how to optimize it.”

But viewing the process with atomic precision was simply impossible—until nine months ago. In January 2024, Dravid’s team unveiled a novel method to analyze gas molecules in real time. Dravid and his team developed an ultra-thin glassy membrane that holds gas molecules within honeycomb-shaped nanoreactors, so they can be viewed within high-vacuum transmission electron microscopes.

With the new technique, previously published in Science Advances, researchers can examine samples in atmospheric pressure gas at a resolution of just 0.102 nanometers, compared to a 0.236-nanometer resolution using other state-of-the-art tools. The technique also enabled, for the first time, concurrent spectral and reciprocal information analysis.

Incredibly Rare 13 In 100 Billion Event Seen At CERN Particle Accelerator

Posted by in category: particle physics

In 2020, the team reported evidence of this rare form of decay being detected by the experiment. Now, after far more collisions, including higher-energy collisions, the team reports a 5-sigma detection, meaning there is a 0.00006 percent chance that the detection is a statistical fluke.

“With this measurement, K+ → π+νṽ becomes the rarest decay established at discovery level – the famous 5 sigma,” Cristina Lazzeroni, Professor in Particle Physics at the University of Birmingham, said in a statement. “This difficult analysis is the result of excellent teamwork, and I am extremely proud of this new result.”

Boom Supersonic’s New Overture Aircraft is Set to Be Faster Than the Concorde

Posted by in categories: sustainability, transportation

American start-up Boom Supersonic is planning to develop the very first supersonic aircraft powered by 100% sustainable fuel. The aircraft, named Overture, would succeed Concorde in providing ultrafast connections between Europe and the United States, more than 20 years after the latter ceased operation. The new aircraft also echoes its predecessor’s unique, long and slender design.

Boom Supersonic is currently flying a demonstrator, the XB-1, over the Mojave Desert in California. A first supersonic flight (at Mach 1) is now expected by the end of 2024, following the green light given from the Federal Aviation Administration (FAA). All these tests are designed to ensure the aircraft’s reliability and maneuverability. Above all, they lay the foundations for the firm’s future Overture plane.

MIT scientists use a new type of nanoparticle to make vaccines more powerful

Posted by in categories: biotech/medical, nanotechnology

Many vaccines, including vaccines for hepatitis B and whooping cough, consist of fragments of viral or bacterial proteins.


“Not only are we delivering the protein in a more controlled way through a nanoparticle, but the compositional structure of this particle is also acting as an adjuvant,” Jaklenec says. “We were able to achieve very specific responses to the Covid protein, and with a dose-sparing effect compared to using the protein by itself to vaccinate.”
