Addendum: Magnetic field screening in hydrogen-rich high-temperature superconductors

In our paper 1 , we studied the magnetic response of H 3 S and LaH 10 superconductors to an applied magnetic field using Superconducting Quantum Interference Device (SQUID) magnetometry. Prof. Hirsch, in his Matters Arising entitled “On the Author Correction to “Magnetic field sc...

Comparison of the Error Incurred in the Measurement of Nonblinking, Nonpoint-Source Objects Using Classical and Quantum Imaging

Abstract We present another step in our efforts to expand far-field imaging beyond the diffraction limit and beyond the limitations imposed by fluorescent labels. The model system we examine is based on the exploitation of entangled photon pairs at 810 nm generated by spontaneous...

Mixed Valence-Driven Phase Evolution and Property Tuning in PdSe2

Abstract Layered palladium diselenide (PdSe2) is an emerging functional dichalcogenide whose structural flexibility enables tunable electronic, magnetic, and transport properties. However, controlled access to compositionally substituted and metastable polymorphs remains challeng...

A Live Single-Cycle RSV Vaccine with Immune Responses Focused on Prefusion F and the Central Conserved Region of Attachment Protein G

Respiratory syncytial virus (RSV) is a major cause of severe lower respiratory tract disease in infants and children, and a pediatric vaccine is not available. Among various approaches, live vaccines are attractive as they induce broad multi-antigenic responses and have never bee...

Development of a Ca-K-Li-RE-Cl (RE = La, Ce, Pr, Nd) rare-earth molten salt database: RE-Cl and CaCl2-RECl3 binary systems

During molten salt electrolysis of rare earths, the presence of multiple oxidation states of the rare earths can greatly affect Faradaic yields. The stability of these different oxidation states can be controlled by the composition of the molten salt. To assess the stability of t...

Reproducibility, Replicability, and Research Quality in Homogeneous Catalysis

Abstract Researchers from all sectors of homogeneous catalysis convened in response to concerns regarding reproducibility in science to analyze the issue and provide recommendations. In addition to an in-person workshop, the group engaged the broader homogeneous catalysis communi...

Robust Antiferroelectric Response in the Pbca Phase of Hafnium Zirconium Oxide via Aluminum Substitution

ABSTRACT Hafnium zirconium oxide (HZO) has attracted attention for applications in nonvolatile memory and energy harvesting devices. However, it faces practical challenges such as insufficient endurance. One promising strategy to address this limitation is the utilization of anti...

miR172 ‐ AP2 Controls Age‐Dependent Regeneration Competence in Populus

ABSTRACT Plants maintain remarkable regenerative potential, yet this capacity declines with developmental age, limiting clonal propagation and biotechnological applications. Here, we show that the miR172‐AP2 module serves as a central determinant of regeneration competence in Pop...
