The paper below was recently published by researchers at Argonne National Laboratory (ANL) and explores innovative methods for investigating mesoscale grain structures with a focus on dark field X-ray microscopy (DFXM). The paper demonstrates the capability of BrillianSe approaching nanoscale resolution which is particularly crucial when investigating weak diffraction signals in magnetic systems, quantum materials, and thin films. In addition to providing insights into the breakthrough applications mentioned above, the researchers at ANL compared the BrillianSe X-ray detector with routinely used scintillator-based optical detection. The results were impressive, showing an order of magnitude improvement in exposure times. This enhancement allows for the imaging of weakly diffracting ordered systems, opening new possibilities for research. Are you attending the APS/CNM Users Meeting next week at ANL? Make sure you stop by our booth to talk more about potential applications for our innovative line of detectors. https://lnkd.in/gSdcKrK6 #synchrotron #xrayimaging #ANL #APS #CNM

In five new Nature Communications papers, the team behind NASA’s successful Double Asteroid Redirection Test (DART) mission sheds new light on the structure and origins of the asteroid system encountered in 2022. https://jhuapl.link/fhk Researchers from Johns Hopkins APL and several international partner institutions provide a detailed overview and interpretation of the geological findings at Didymos and Dimorphos. Analysis suggested that both Didymos and Dimorphos have weak surface characteristics, which led the team to posit that Didymos has a surface age 40-130 times older than Dimorphos, with the former estimated to be 12.5 million years old and the latter less than 300,000 years old. The low surface strength of Dimorphos likely contributed to DART’s significant impact on its orbit. These latest findings form a more robust overview of the origins of the Didymos system and add to the understanding of how such planetary bodies were formed. They also provide new insights into why DART was so effective in shifting Dimorphos’ orbit. #JHUAPL | #DARTMission | #PlanetaryDefense | NASA - National Aeronautics and Space Administration

🌌 CENTRA Research News! 🌌 Masato Minamitsuji, #FCT postdoc at Instituto Superior Técnico, recently published the paper titled "Even-parity black hole perturbations in minimal theory of bigravity" in Physical Review D - American Physical Society! In this work, they study even-parity black hole perturbations in the minimal theory of bigravity, using the Schwarzschild solution in spatially flat coordinates as the background. They analyze the gauge transformations for the ℓ=0, 1, and ℓ≥2 modes, focusing on the effectively massless case where the ratio of proper times between the physical and fiducial sectors is set to unity. The study reveals that ℓ=1 perturbations vanish when regularity is imposed at spatial infinity, and for ℓ≥2 modes, they identify two propagating modes and four instantaneous modes in the effectively massless scenario. 🔗 Dive into the paper here: https://lnkd.in/dBxuxCHq Fundação para a Ciência e a Tecnologia (FCT) #Physics #BlackHoles #GravitationalTheory #Bigravity #ScientificResearch #Astrophysics #CENTRA #GeneralRelativity #TheoreticalPhysics

Time-dependent Kohn-Sham (TDKS) can be used to simulate X-ray absorption spectra, but transitions to the continuum often contaminate the predicted spectra in ways that obscure key information. In the paper linked below, the developers of this feature demonstrate a new dipole filtering approach (now available in Q-Chem 6.2), which can be used to remove these continuum artifacts in the TDKS spectra, providing a useful approach for X-ray spectroscopy modeling!

Interesting: Fusion fuel could burn 10x more efficiently by aligning its quantum spin first! 🌀 Researchers Jason Parisi, Ahmed Diallo, and Jacob Schwartz at Princeton Plasma Physics Laboratory (PPPL) have shown that spin-polarizing deuterium and tritium fuel makes tritium burn far more efficiently. This approach reduces tritium use, shrinks reactor size, cuts costs, and enhances safety—paving the way for more practical fusion power plants.
