A High-Density Supercritical Fluid of H2
Abstract This study aimed to elucidate the structural evolution of supercritical fluid hydrogen (SCF H2) under high pressure. X-ray diffraction was performed on SCF H2 using synchrotron radiation at room temperature. The structure factor S(Q) was observed in a low-Q region at eac...

A Well-Being-Centric Walkable Tourism Platform Using AI Agent
We propose a Well-Being-Centric Walkable Tourism Platform Using AI Agent that fuses heterogeneous urban data—an OSM pedestrian graph, a city-scale microclimate field, and a walkability layer for Sofia, Bulgaria—with an AI agent that converts freetext user requests into a constrai...

Impact of Inhibitor Size and Flexibility on the Binding Pathways to c-Src Kinase
Abstract The conformational plasticity of protein kinases poses a challenge for inhibitor design, motivating the use of molecular dynamics (MD) simulations to study their dynamic binding processes. While conformational changes are increasingly discussed, the impact of drug compou...

A Capsid Tyrosine Residue Governs the Proteolytic Inactivation of Echovirus 11 in Lakewater
Abstract Enteroviruses are environmentally transmissible human pathogens whose stability in natural waters varies widely, yet the molecular determinants underlying this variability remain largely unknown. Echovirus 11 (E11), a reemerging cause of severe neonatal infections, is ef...

Staggered Quadruple-Rutile Oxides as Low-Strain and High-Power Anodes for Lithium-Ion Batteries
Abstract Tunnel-structured oxides provide attractive hosts for lithium-ion storage. However, their application is frequently limited by structural instability or sluggish ion transport at high lithium contents. Here, we demonstrate that the staggered quadruple-rutile framework re...

Controlling Valence Band for Cu2Sn0.38Ge0.62S3 Particles via Li Substitution at Cu Sites
Abstract Cu2(Sn,Ge)S3 (CTGS) is a promising near-infrared-responsive photocathode material whose conduction band minimum can be tuned by varying the Sn/Ge ratio, whereas direct control of the valence band maximum (VBM) remains challenging because of the large Cu 3d contribution t...

A Programmable Nanovesicle Platform for MegapascalPressure Sensing
Abstract Hydrostatic pressure (HP) is a subtle yet pervasive force that shapes chemistry and biology from the ocean floor to living cells─yet real-time HP sensing at the microscale remains elusive. Here, we report pyrene-modified polyionic complex vesicles (Pyr-PICsomes) as a cla...

A ComplexSpin-Transition Thermal Hysteresis Unlockedby Two Competing Symmetry-Breakings
Abstract The spin-crossover material [Fe(NH2trz)3](NO3)2 belongs to the class of 1D triazole-based polymeric SCO complexes. It exhibits a thermal phase transition, with a 28 K wide thermal hysteresis, characterized by phase transition temperatures T↑ = 346 K upon warming and T↓ =...

Coordination-Driven Transport in Chloroaluminate Electrolytes
Abstract Transport in electrolytes reflects both the stability of coordination complexes and their dynamic reorganization through chemical bond association and dissociation. Establishing an atomistic description of how the dynamic coordination governs equilibrium speciation and t...
