Enhanced Tantalum Superconducting Resonator Performance via All‐Surface Organic Monolayer Passivation

Advanced Functional Materials, EarlyView.
The internal quality factor of tantalum superconducting resonators is significantly increased by ∼140% in the low photon regime by passivating their surfaces with a high‐quality alkene self‐assembled monolayer. Our methodology promises to enhance the performance of superconducting quantum circuits.

THE VACUUM DNA - GEOMETRIC UNIFICATION OF PARTICLE PHYSICS AND COSMOLOGY VIA 3/2-BRANE RESONANCE

This framework formalizes the Emergent Resonance Brane (ERB) theory, providing a first-principles derivation of fundamental constants as geometric invariants. We demonstrate that the vacuum is not a void but a refractive, coupled S² × S² manifold. Reality is defined as the stationary wave solution of a 3/2-brane collision, whose structural topology ...

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

Advanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Three Modes of Universal Resonance Evidence from Riemann Zeta Function, Particle Physics, and Complex Dynamics

This paper completes the Resonant Ontology framework by identifying a third fundamental mode of universal resonance through analysis of the Riemann zeta function. Building upon six prior systems that revealed the Critical Mode (Δ ≈ 0.382) and Structural Mode (Δ ≈ 0.687), this work discovers a previously unknown equilibrium state—Homeostatic Mode (Δ ≈ 0.

Particle physics models with four generations [PDF]

, 2012
In this thesis we consider extending the standard model of particle physics (SM) to include a fourth generation of elementary particles (SM4). The fourth generation would have to be sufficiently heavy to have escaped detection; specifically, its neutrino

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

Advanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Excitation of toroidal Alfvén eigenmode by energetic particles in DTT and effect of negative triangularity

Nuclear Fusion
A linear gyrokinetic eigenvalue code is developed to study the stability of toroidal Alfvén eigenmode (TAE) in general axisymmetric toroidal geometry, with a self-consistent treatment of energetic particle drive and core plasma Landau damping in a non ...

Energy dependence of particle ratio fluctuations in central Pb+Pb collisions from [v]sNN=6.3 to 17.3 GeV [PDF]

, 2009
We present measurements of the energy dependence of event-by-event fluctuations in the K/π and (p+p̅ )/π multiplicity ratios in heavy-ion collisions at the CERN SPS.

Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing

Advanced Functional Materials, EarlyView.
Maskless direct laser writing enables local control of oxygen stoichiometry in epitaxial YBCO thin films under ambient conditions. Sub‐micrometer grayscale patterns with tunable optical response and superconducting transport properties are achieved.
