Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields

Angewandte Chemie, EarlyView.
Four heavy Hg(II) coordination networks with paramagnetic Fe(II) sites reveal strong and halogen‐tunable low‐frequency (LF) sub‐terahertz phonons and field‐dependent magnetic transitions. LF phonon spectroscopy and Raman magnetospectroscopy are powerful probes of structure, low‐energy vibration, zero‐field splitting, and spin–phonon coupling supported ...

Pyrolyzed Photoresist as a Continuous‐Tone Mask for Grayscale Lithography

Advanced Science, EarlyView.
True grayscale contact photolithography masks are created by pyrolysis of 3D multiphoton resist patterns. The resulting carbon masks retain micrometer‐scale patterned features while providing continuous‐tone optical transmission. This approach provides access to high‐quality grayscale lithography without requiring exotic materials or commercial mask ...

Hydrogen‐Bonding Order Associated With Radical Delocalization in Layered Organic Cathode Materials

Angewandte Chemie, EarlyView.
“TAQ” and TAPT share the same pyrazine‐based molecular structure but differ in degree of crystallinity. Combined x‐ray scattering, solid‐state NMR, MicroED, and EPR reveal that “TAQ”'s higher crystallinity and ordered hydrogen‐bonding network are associated with enhanced radical delocalization and conductivity, highlighting structural order as a design

Finslerian extension of an anisotropic strange star in the domain of modified gravity

European Physical Journal C: Particles and Fields
In this article, we apply the Finsler spacetime to develop the Einstein field equations in the extension of modified geometry. Following Finsler geometry, which is focused on the tangent bundle with a scalar function, a scalar equation should be the ...

Advances in Josephson Junction Materials and Processes Toward Practical Quantum Computing

Advanced Science, EarlyView.
Emerging materials for quantum computing, including crystalline materials, two‐dimensional van der Waals materials, two‐dimensional electron gas systems, ferromagnets, and unconventional (e.g., d‐wave) superconductors, offer opportunities to engineer next‐generation Josephson junctions.

Injectable Peptide‐Based Functional Amyloid Hydrogels as Tunable Depots for Sustained Drug Delivery

Advanced Science, EarlyView.
An injectable and tunable peptide‐based functional amyloid hydrogel provides sustained insulin release while preserving insulin stability and bioactivity. The hydrogel enables prolonged glycemic regulation in vivo, exhibits excellent biocompatibility, and shows no detectable IAPP and α‐Syn heterologous cross‐seeding, highlighting its potential as a ...

CR immersions and Lorentzian geometry Part II: A Takahashi type theorem

, 2013
Using tools from Lorentzian geometry (arising 1 from the presence of the Fefferman metric) we prove a Takahashi type theorem (for a class of pseudohermitian immersions covered by connection-preserving equivariant immersions among the total spaces of the

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

Advanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.
