Dielectric Behaviour of Acrylic and Natural Rubber Dielectric Elastomers: Combined Effects of Frequency, Temperature and Mechanical Pre-stretch

This study investigates how frequency, temperature, and mechanical pre-stretch jointly influence the dielectric constants of acrylic (VHB 4910) and natural rubber (Oppoband 8001) elastomers, revealing that the acrylic variant exhibits significantly higher sensitivity to these factors due to its polar backbone, thereby providing critical data for optimizing material selection in soft robotic applications.

Evolution of TRi-structural ISOtropic (TRISO) Fuel Material Properties Under Simulated Repository Irradiation Conditions

This study demonstrates that alpha and gamma irradiation under deep geological repository conditions induce structural and mechanical changes in TRISO fuel's PyC and SiC layers, including increased brittleness and lack of thermal recovery, which could compromise long-term containment integrity.

Nanoparticulate selective emitters for effective radiative cooling in urban heat islands

This study demonstrates that nanoparticulate selective emitters (Nano-SEs) significantly outperform broadband alternatives in mitigating urban heat islands by achieving lower surface temperatures under the restricted sky view factors typical of dense cityscapes, thereby offering a scalable solution for enhancing urban thermal resilience.

Impact-Triggered Seismicity: Essential Physics and a Hierarchical Modeling Framework

This paper establishes a hierarchical modeling framework demonstrating that impact-triggered seismicity on the San Andreas Fault is primarily governed by elastic wave propagation and velocity-dependent friction within the first 100 seconds, predicting that meteorite impacts exceeding 10¹⁴–10¹⁵ J at distances of 20–100 km could trigger major earthquakes based on a derived scaling law linking critical energy to fault stress and distance.

A 2D Hydrothermodynamic Analytical Model for Rapid Tumor Ablation using High-Intensity Focused Ultrasound

This paper presents a self-consistent 2D hydrothermodynamic analytical model that derives explicit scaling laws for rapid, non-invasive tumor ablation by demonstrating how a stationary cellular matrix converts acoustic momentum into static pressure gradients and identifying an optimal absorption-depth relationship to achieve sharp thermal lesion boundaries while preventing upstream overheating.

Circuit models for quasi-static bands in metallic photonic crystals

This paper introduces a wiring-based circuit model that analytically determines the zero-frequency touching sets and multiplicity of quasi-static bands in slender, lossless metallic photonic crystals by leveraging return-translation subgroups and electrostatic properties, thereby unifying the derivation of screening behaviors and plasma cutoffs across various periodic geometries without relying on specific inductive parameters.

Mechanical and Interfacial Properties Characterization of Physical Vapor Deposited Metallic Films after Rapid Thermal Annealing

This study investigates the effects of Rapid Thermal Annealing temperature on the mechanical properties, interfacial adhesion, and microstructural evolution of Physical Vapor Deposited aluminum and copper films, revealing that while annealing reduces hardness and elastic modulus, it can enhance adhesion strength through grain growth and surface morphology changes, thereby providing critical insights for optimizing processing parameters in semiconductor applications.

A Comparative Study of Coherent and Incoherent Error Models for superconducting Transmon Arrays

This paper presents an end-to-end simulation framework that maps fabrication-induced Josephson junction variations to qubit frequency detuning and demonstrates that a coherent ZZZZ error model, unlike a probabilistic depolarizing model, is essential for accurately capturing oscillatory fidelity revivals and identifying non-perturbative regimes in superconducting transmon arrays.
