Advanced Functional Materials, EarlyView.The intrinsic distortion‐rich lattice of HEPBA with GQD‐enabled microstrain engineering establishes a mechanistic route toward high‐performance alkaline hydrogen evolution reaction. HEPBA inherently feature heterogeneous local coordination environments arising from multimetal incorporation, while properly introducing GQD during coprecipitation ...

Dynamic Quantum Vacuum and Relativity [PDF]
, 2016 A model of a three-dimensional dynamic quantum vacuum with variable energy density is proposed. In this model, time we measure with clocks is only a mathematical parameter of changes running in quantum vacuum. Mass and gravity are carried by the variable

Advanced Functional Materials, EarlyView.Programmable 2D magnetic clusterphenes are realized through a ligand‐mediated cluster‐assembly strategy. Direct linking of magnetic superatomic clusters enhances electron delocalization and symmetry breaking, enabling the concurrent strengthening of magnetic exchange interactions and spin–orbit coupling.

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.

Take a Ride on a Time Machine [PDF]
, 2003 We discuss the possibility to build and operate a time machine, a device that produces closed timelike curves (CTCs). We specify the spacetime structure needed to implement a time machine and assess attempted no-go results against time machines in ...

Theoretical Calculation of Vacuum Energy Density Based on the Fractal Quantum Gravity Theory
Reports in Advances of Physical SciencesThere has been a huge discrepancy between the vacuum energy density calculated based on the existing quantum theories and the observational values. The calculated vacuum energy density is about 120 orders of magnitude greater than its observational ...

Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal
Advanced Functional Materials, EarlyView.Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...
