Optimization of Pulsed Saturation Transfer MR Fingerprinting (ST MRF) Acquisition Using the Cramér–Rao Bound and Sequential Quadratic Programming

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 3, Page 1778-1790, March 2026.
ABSTRACT Purpose To develop a method for optimizing pulsed saturation transfer MR fingerprinting (ST MRF) acquisition. Methods The Cramér–Rao bound (CRB) for variance assessment was employed on Bloch–McConnell‐based simulated signals, followed by a numerical sequential quadratic programming optimization and basin‐hopping avoidance of local minima ...

Nonlocal Electrical Detection of Spin‐Polarized Surface Currents in the 3D Topological Insulator BiSbTeSe2

open access: yesphysica status solidi (b), Volume 263, Issue 3, March 2026.
Nonlocal (NL) electrical measurements in the topological insulator BiSbTeSe2 reveal spin‐polarized surface currents, which vanish around 20 K due to increased interactions between bulk and surface states. An enhanced spin‐to‐background ratio in the NL geometry compared to the local geometry provides new insights into spin transport and current pathways

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

open access: yesSmall, Volume 22, Issue 13, 3 March 2026.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Ions as Architects of DNA Nanostructures: Mechanisms, Simulations, and Technological Frontiers

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Ions are not merely passive electrolytes but active regulators of DNA nanostructures. This review shows how ion valence, hydration, and specificity govern electrostatic screening, correlation, and confinement, enabling DNA origami, metallized DNA, nanopores, hydrogels, DNAzymes, molecular machines, and energy devices through integrated experimental and

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

A dedicated beamline for wide‐energy‐range X‐ray spectroscopy at SSRF: combining soft and hard X‐ray capabilities

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 2, Page 523-530, March 2026.
A wide‐range beamline (130–10000 eV) combining both soft X‐ray and hard X‐ray photons has been constructed at SSRF for in situ X‐ray photoemission spectroscopy investigations of the solid–gas interface, and for hard X‐ray photoemission spectroscopy studies with layer‐by‐layer resolution.The advancement of renewable energy critically depends on the ...
