This is such a cool example of overlapping scientific domains in applied research. A study shows that neutrons can bind to nanoscale atomic clusters, known as quantum dots. This exciting discovery may provide valuable insights into material properties and quantum effects. #Science #Technology #QuantumDots

Researchers at MIT have found that neutrons can actually be made to cling to particles called quantum dots, which are made up of tens of thousands of atomic nuclei, held there just by the strong force. The new finding may lead to useful new tools for probing the basic properties of materials at the quantum level, including those arising from the strong force, as well as exploring new kinds of quantum information processing devices. The work is reported this week in the journal ACS Nano, in a paper(https://lnkd.in/ejnB_Azs) by MIT graduate students Hao Tang and Guoqing Wang and MIT CQE members, MIT professors Ju Li and Paola Cappellaro of the Department of Nuclear Science and Engineering. The reason this new finding is so surprising, Li explains, is because neutrons don’t interact with electromagnetic forces. Of the four fundamental forces, gravity and the weak force “are generally not important for materials,” he says. “Pretty much everything is electromagnetic interaction, but in this case, since the neutron doesn’t have a charge, the interaction here is through the strong interaction, and we know that is very short-range. It is effective at a range of 10 to the minus 15 power,” or one quadrillionth, of a meter.

It was great to have so much representation at the MaThRad: Mathematical Theory of Radiation Transport Workshop, based at UKAEA (Culham) this year. Alex Valentine, Ross Worrall and Lee Evitts from the Applied Radiation Technology group presented some of our most challenging Monte Carlo and inverse problems to an audience keen to use modern mathematical methods to explore and address these key areas for fusion research. The challenges we raised were around:  1. scaling with the increasing complexity of geometries, including efficiently tracking algorithms for large heterogeneous problems, optimising geometry construction, and how we might couple detailed neutronics calculations with computational fluid dynamics. 2. quantification and propagation of nuclear data uncertainty in the total Monte Carlo method, including methods to handle the non-continuous behaviour of perturbed cross-section files, identifying the biggest contributor of uncertainty for a particular geometry, and coupling total Monte Carlo with variance reduction techniques. 3. identifying, quantifying and mitigating the unknown unknowns of neutron spectrum unfolding - information that is lost during the unfolding process due to the highly underdetermined nature of the problem, and propagating uncertainties. We received encouraging feedback from attendees, and would be keen to hear if anyone is interested in exploring these challenge areas with us.

I'm thrilled to share that we have two new papers published, pushing the limits of high-field EPR spectroscopy: 1️⃣ "High-field pulsed EPR spectroscopy under magic angle spinning" in Science Advances. We demonstrate the first pulsed EPR experiments under magic angle spinning (MAS) at 7 T, revealing unique effects on EPR line shapes, intensity, and signal dephasing. This opens new avenues for studying MAS-DNP mechanisms. https://lnkd.in/diPj2vfc 2️⃣ "On the peculiar EPR spectra of P1 centers at high (12–20 T) magnetic fields" in Physical Chemistry Chemical Physics. This study investigates the complex behavior of P1 centers in diamonds at ultra-high fields, showing how state mixing under the cancellation condition affects their EPR spectra and spectral diffusion, with implications for DNP applications. https://lnkd.in/dBH7QpPj Both works advance our understanding of spin systems at high magnetic fields. Excited to see where this leads next!

Scientists and engineers at MIT discover neutrons (n) cling to nanoparticles of lithium hydride.  I, Reginald B. Little (RBL), take interest in such experimental discovery (by these MIT researchers led by Prof Ju Li and Prof Paola Cappellaro) because I have for over 20 years speculated and given theory of such strong forces (SF) of bare n and bare p interacting with some molecules and nanoparticles by nuclear magnetic moments (NMMs) for catalyzing chemical reaction dynamics. But in 2002-03, Reginald B. Little proposed that the SF can act (bleed) outside the nucleus and action many atoms even nanosize group of atoms. Such extranuclear action of SF was reasoned by RBL as due to perturbations for altering SF internal dynamics for fractional reversible fissing and fusing beyond the nuclei. RBL in 2003 applied his theory of thermal n interacting by their strong forces (SF) by complex magnetism rather than kinetic collisions with nano-catalysts of iron, cobalt and/or nickel to alter carbon nanotube, graphene and nano-diamond formations. Such theory of RBL was presented in 2003 in a proposal submitted to Oak Ridge National Laboratory (such proposal was in 2003 also reviewed independently by program officers at Canadian Nuclear Laboratories and NIST). RBL's 2003 proposal asserted: "On the basis of these successes, this work now predicts and attempts to better stimulate high spin carbon intermediates by neutron irradiation during carbon chemical vapor deposition." In 2004, RBL then submitted US patent to protect his idea of thermal n by SF releasing complex magnetic fields for interacting with molecules and nanoparticles by Little's Effect. In 2005, RBL develop his idea more of n and p interacting with surrounding atoms, molecules and nanoparticles in unique ways by their SF(s) releasing complex dense magnetic fields by Little's Effect as RBL present a theory of the origin of the SF based on complex rotating and revolving magnetic fields produced within up and down quarks for binding 2 up and a down quark (for proton) and binding 2 down and an up quark (for neutron) for agitations by Little's Rules disrupting the triples of dense spinrevorbitals for seeping the strong force (SF) outside the quarks for manifesting gluons and the further seeping and bleeding of these complex magnetic fields outside n and p to manifest nuclear force and further seeping of such fields outside nuclei into surrounding electronic shells. RBL applied such in 2005 to explain the structure of p and n and transmutations of p+ and e- to n. In 2021, RBL applied such theory of p+ and n strong force (SF) binding surrounding atoms to propose mechanism for separating Lithium and hydrogen from alkali, alkaline earth and transition metal cations in geothermal salar brines based on their different NMMs by magnitudes and chiralities and emphasizing stronger interactions by s orbital. In 2018, RBL summarized these series of papers and this effect of SF of n and p creating novel magnetism.

🎉 Exciting News from our Lab! 🎉 We are thrilled to announce a new publication from the lab, authored by Akanksha Gautam. 📚✨ 📝 Title of the Paper: Phase retrieval in inverse ghost diffraction using Sagnac interferometer 🔍 Journal: Journal of Optics The article presents a novel technique for retrieval of two-dimensional phase objects in the ghost diffraction scheme from inversion of the experimentally measured two-point complex correlation function in a first-order interferometer. Ghost diffraction (GD) involves using non-local spatial correlations to image objects with light, which has not interacted with them. The GD scheme is experimentally implemented by a specially designed experimental setup wherein one of the orthogonal polarization components of the transversely polarized light interacts with the object and the other polarization component of the light remains intact and directly reaches the detector. The Fourier spectrum of the object is encoded into the two-point spatial correlation of these two orthogonal polarization components which is experimentally detected in an interferometer with a radial shearing in the Sagnac geometry. We experimentally demonstrated imaging of spatially varying phase objects and results are presented for three different cases.

Sir Ernest Rutherford, a pioneer in atomic and nuclear physics, won the 1908 Nobel Prize in Chemistry. His coat of arms says: "To seek the first principles of things". Before machine learning’s triumph, the first-principles or physical model is a major method to predict the folding of proteins. Yet, we need an expensive supercomputer or designed ASIC (like Anton) to achieve the long-time-scale folding simulation. Nowadays, everyone can use our local personal computers or even laptops for protein structure prediction, thanks to the decades of "stamp collecting". This protein discovery process is decentralized and achieves so-called research "democracy". #nobelprize #chemistry #physics #drug #CADD #drugdiscovery #Biotechnology #Pharmaceuticals ------ This offensive sentence, "All Science Is Either Physics or Stamp Collecting", may not said by Sir Ernest Rutherford directly. It first appeared in the 1939 book “The Social Function of Science” by physicist John Desmond Bernal who ascribed the idea to Ernest Rutherford, but Bernal did not present a precise quotation. 

2025 marks the 100th anniversary of the formulation of quantum mechanics! It is so far the best theory we have to understand our physical world. Among other things, it has led to the development of modern electronics; it is providing a platform, e. g. quantum simulators, for the engineering of novel materials; and it is enabling the development of technologies for nuclear fusion in order to address the energy crisis.
