Nanoplastics put stress on trees and impair photosynthesis

Posted by in categories: biological, nanotechnology, particle physics

And, if its in trees, guess where else it is, Crisis Yet? or nah.


It is well known that more and more plastic waste is ending up in soil and bodies of water. Researchers are particularly concerned about tiny micro-and nano-sized particles. It remains unclear how and to what extent they are able to enter living organisms—and what effect they may have on metabolism.

Rare earth single atoms enhance manganese oxide’s electrochemical oxygen evolution

Posted by in categories: chemistry, particle physics, sustainability

An international group of researchers has developed a novel approach that enhances the efficiency of the oxygen evolution reaction (OER), a key process in renewable energy technologies. By introducing rare earth single atoms into manganese oxide (MnO2), the group successfully modulated oxygen electronic states, leading to unprecedented improvements in OER performance.

Investigating nonlinear magnetohydrodynamics in an optimized, reactor-scale quasi-axisymmetric stellarator

Posted by in categories: evolution, particle physics

We use the new simulation capabilities of the extended-magnetohydrodynamic (MHD) code, M3D-C1, to investigate the nonlinear MHD properties of a reactor-scale quasisymmetric stellarator equilibrium. Our model captures the self-consistent evolution of the magnetic field, temperature, density, and flow profiles without imposing restrictions on the structure of the first. We include the effects of resistivity using a realistic temperature-dependent Spitzer model, along with a model for heat transport that captures the key physical characteristic, namely, strongly anisotropic diffusion in directions perpendicular and parallel to the magnetic field. We consider a quasi-axisymmetric, finite-pressure equilibrium that was optimized for self-consistent bootstrap current, quasi-symmetry, and energetic particle confinement. Our assessment finds that the equilibrium is highly unstable to interchange-like pressure-driven instabilities near the plasma edge. The initially unstable modes rapidly destabilize other modes in the direction of the N-fold rotational symmetry (toroidal, in this case). For this equilibrium, N = 2, meaning destabilization of a large number of even-numbered toroidal Fourier modes. Thus, field-periodicity is likely to be an important factor in the nonlinear MHD stability characteristics of optimized stellarators.

Microwave Control of the Tin-Vacancy Spin Qubit in Diamond with a Superconducting Waveguide

Posted by in categories: computing, particle physics, quantum physics

The tin-vacancy center in diamond has properties that could be useful for quantum networks.

In a new study, researchers show how this defect’s electron spin can be controlled — and coherence prolonged — using a superconducting microwave waveguide.


Even the most pristine diamonds can host defects arising from missing atoms (vacancies) or naturally occurring impurities. These defects possess atomlike properties such as charge and spin, which can be accessed optically or magnetically. Over the past few decades, researchers have studied various defects to understand and harness these properties. One in particular—the tin-vacancy center, in which a tin atom resides on an interstitial site with two neighboring vacancies—exhibits exceptionally useful optical and spin properties, making it highly relevant in the field of quantum communication. Here, we explore how the spin properties behave under different magnetic field directions.

New research suggests a way to capture physicists’ most wanted particle—gravitons

Posted by in categories: particle physics, quantum physics

A team led by Stevens professor Igor Pikovski has just outlined how to detect single gravitons, thought to be the quantum building blocks of gravity—and making that experiment real should be possible with quantum technology, they suggest, in the near future.

A history of the electron: JJ and GP Thomson

Posted by in category: particle physics

J.J. Thomson won the Nobel Prize in physics in 1906 showing that the electron is a particle: ironically, his son, G.P. Thomson, won the Nobel Prize in physics in 1937 showing that it is not (or rather that the electron can also behave as a wave)


A tale of two Thomsons.
