Machines have evolved to meet the demands of daily life and industrial use, with molecular-scale devices often exhibiting improved functionalities and mechanical movements. However, mastering the control of mechanics within solid-state molecular structures remains a significant challenge.

Researchers at Ulsan National Institute of Science and Technology (UNIST), South Korea have made a groundbreaking discovery that could pave the way for revolutionary advancements in data storage and beyond. Led by Professor Wonyoung Choe in the Department of Chemistry at UNIST), a team of scientists has developed zeolitic imidazolate frameworks (ZIFs) that mimic intricate machines. These molecular-scale devices can exhibit precise control over nanoscale mechanical movements, opening up exciting new possibilities in nanotechnology.

The findings have been published in Angewandte Chemie International Edition (“Zeolitic Imidazolate Frameworks as Solid-State Nanomachines”).

Advanced materials, including two-dimensional or atomically thin materials just a few atoms thick, are essential for the future of microelectronics technology. Now a team at Los Alamos National Laboratory has developed a way to directly measure such materials’ thermal expansion coefficient, the rate at which the material expands as it heats. That insight can help address heat-related performance issues of materials incorporated into microelectronics, such as computer chips.

The research has been published in ACS Nano (“Direct measurement of the thermal expansion coefficient of epitaxial WSe 2 by four-dimensional scanning transmission electron microscopy”).

“It’s well understood that heating a material usually results in expansion of the atoms arranged in the material’s structure,” said Theresa Kucinski, scientist with the Nuclear Materials Science Group at Los Alamos. “But things get weird when the material is only one to a few atoms thick.”

What would Brian Greene do if he could travel through time, and which future technology is he most excited about?

After our full interview, I had the privilege to sit down with Brian and ask him a few more questions. Enjoy this exclusive Q\&A with one of the most renowned physicists of our time!

China has released video footage of its rifle-toting robot dogs, and it’s about as scary as you were probably imagining.

Last week, Agence France-Presse reported that China had flaunted the gun-carrying robodogs in a 15-day joint military exercise with Cambodia dubbed the “Golden Dragon.”

And if images of the literal killing machines weren’t troubling enough, a new video of the robots released yesterday by the state-owned broadcaster China Central Television shows the killing machine dutifully hopping and diving, leading teams in reconnaissance, and shooting its back-strapped machine gun at targets.

For decades, inflation has been the dominant cosmological scenario, but recently the theory has been subject to competition and critique. Two renowned pioneers of inflation — Alan Guth and Andrei Linde — join Brian Greene to make their strongest case for the inflationary theory.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.
