A Unified Configurational Framework for Interface and Bulk Defects in Eshelbian Linear Elasticity

Salvatore Di Stefano, Claudia Binetti, Giuseppe Puglisi, Stefano Giordano

Within the framework of Eshelbian mechanics and linear elasticity, we develop a kinematic and energetic formulation for treating different classes of defects. Central to the approach is a defect map, through which interface discontinuities and bulk material inhomogeneities are described within a…

Chamfer-engineered microcantilever probes for controlled electrical contact formation

Steve Arscott

<div><p>In miniature silicon-based microcantilever probes used for high-frequency on-wafer electrical measurements, microfabrication processes such as etching can produce sharp probe-tip edges and poorly controlled contacting geometries. During electrical contact formation, such…

Visible-Light-Driven Porphyrin/ZnO Nanohybrids for Ultrasensitive Room-Temperature Triethylamine Sensing

van Duy Lai, Thi Nguyet To, Valerio Allegra, Roberto Paolesse, Gabriele Magna, Franco Biasioli, Matteo Tonezzer, Alexandro Catini, Corrado Di Natale

Abstract Real-time monitoring of toxic triethylamine (TEA) at room temperature remains a significant challenge for metal oxide chemiresistors due to their typically high-power consumption and thermal requirements. This work presents a highly responsive, visible-light-activated gas sensor based on…

Nanoscale capacitive tuning of three dimensional terahertz meta-atoms

Usama Iqbal, Dmytro B. But, Théo Hannotte, Peretti Romain, Alexis Jouan, Cheryl Feuillet-Palma, Yanko Todorov

We report terahertz (THz) meta-atom resonators whose resonance can be tuned solely by varying the geometry of nanoscale capacitive elements while keeping the geometry of the inductive loop fixed. The capacitive parts employ a metal–dielectric–metal architecture with subwavelength dimensions,…

Vibrational transportation of deformable axisymmetric particles

Marina Terzi, Vladislav Aleshin, Jules Ghesquiere, Vincent Tournat

A particle on a substrate supporting a surface acoustic wave can experience horizontal drift excited by the dry friction force. The effect is referred to as vibrational transportation, or as a surface acoustic wave motor, and is used in a number of industrial applications. A traditional theory of…
