Chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Stony Brook University (SBU), and their collaborators have uncovered new details of the reversible assembly and disassembly of a platinum catalyst. The new understanding may offer clues to the catalyst’s stability and recyclability.

The work, described in a paper published in the journal Nanoscale (“Unravelling the origin of reaction-driven aggregation and fragmentation of atomically dispersed Pt catalyst on ceria support”), reveals how single platinum atoms on a cerium oxide support aggregate under reaction conditions to form active catalytic nanoparticles — and then, surprisingly, fragment once the reaction is stopped.

Fragmentation may sound shattering, but the scientists say it could be a plus.

Introduction to Quantum Teleportation

Quantum teleportation, a term that sounds like it’s straight out of science fiction, is a very real and advancing field in quantum physics. This groundbreaking technology is not about transporting matter from one place to another but rather involves the transfer of information between quantum particles. This article delves into the science behind quantum teleportation, its potential applications, and the impact it could have on various aspects of our lives.

There’s a hot new BEC in town that has nothing to do with bacon, egg, and cheese. You won’t find it at your local bodega, but in the coldest place in New York: the lab of Columbia physicist Sebastian Will, whose experimental group specializes in pushing atoms and molecules to temperatures just fractions of a degree above absolute zero.

In May 2022, the Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU), launched its precision measurement program. Staff from FRIB’s Low Energy Beam and Ion Trap (LEBIT) facility take high-energy, rare-isotope beams generated at FRIB and cool them to a lower energy state. Afterward, the researchers measure specific particles’ masses at high precision.

Nanoscale materials offer remarkable chemical and physical properties that transform theoretical applications, like single-molecule sensing and minimally invasive photothermal therapy, into practical realities.

The unparalleled features of nanoparticles make them promising for various research and industrial uses. However, effectively using these materials is challenging due to the absence of a rapid and consistent method to transfer a uniform monolayer of nanoparticles, a crucial step in device manufacturing.

One potential solution to this challenge lies in electrostatic assembly processes, where oppositely charged nanoparticles adhere to a surface, forming a monolayer that repels other similarly charged particles from attaching further. While effective, this process is often slow. Nature provides an innovative model to address this limitation through underwater adhesion strategies, which have evolved to circumvent similar problems.

Since Nobel-Prize-winning physicist Frank Wilczek first proposed his theory over a decade ago, researchers have been on the search for elusive “time crystals”—many-body systems composed of particles and quasiparticles like excitons, photons, and polaritons that, in their most stable quantum state, vary periodically in time.

Wilczek’s theory centered around a puzzling question: Can the most stable state of a quantum system of many particles be periodic in time? That is, can it display temporal oscillations characterized by a beating with a well-defined rhythm?

It was quite rapidly shown that time crystal behavior cannot occur in isolated systems (systems which do not exchange energy with the surrounding environment). But far from closing the subject, this disturbing question motivated scientists to search for the conditions under which an open system (i.e., one that exchanges energy with the environment) may develop such time crystal behavior.

Transferring information from one location to another without transmitting any particles or energy seems to run counter to everything we’ve learned in the history of physics.

Yet there is some solid reasoning that this ‘counterfactual communication’ might not only be plausible, but depending on how it works could reveal fundamental aspects of reality that have so far been hidden from view.

Counterfactual physics isn’t a new thing in itself, describing a way of deducing activity by an absence of something. In one sense, it’s pretty straight forward. If your dog barks at strangers, and you hear silence when the front door opens, you’ve received information that says a familiar person has entered your house in spite of the absence of sound.

A new discovery could pave the way for supercapacitors that can charge phones and laptops in 60 seconds and electric cars in a mere ten minutes.

In a press release, the University of Colorado at Boulder announced that its researchers have achieved a breakthrough when it comes to our understanding of the way charged ion particles behave — a discovery that could be the key to figuring out the logistics for the long-anticipated energy storage capabilities of supercapacitors.

Supercapacitors have long been proposed as a means of charging electronics lightning-fast, but until now, figuring out how to increase the energy density to match or exceed those of lithium-ion batteries has, for the most part, eluded scientists. Compared to conventional batteries, which can store as much as ten times more energy than today’s supercapacitors, this technology has remained in the realm of the possible but not yet practical.

Fewer miniature black holes found:

Researchers at the University of Tokyo have found that the universe contains far fewer miniature black holes than previously thought, potentially shaking up current theories about dark matter.

Using advanced quantum field theory, typically reserved for subatomic particles, they applied this understanding to the early universe. They discovered new insights into primordial black holes (PBHs), which have been a strong contender for dark matter. Upcoming observations could soon confirm their surprising findings.
