Friction influence on brake squeal in disc and drum brakes using complex eigenvalue analysis [PDF]
Revista Brasileira de Ensino de FísicaBrake noise, is a complex issue in automotive and industrial systems caused by friction-induced vibrations between the brake pad and disc. This noise impacts vehicle performance, accelerates component wear, and diminishes consumer satisfaction.

Advanced Materials, EarlyView.Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Defect‐Templated Phase Engineering in Atomically Thin Metals
Advanced Materials, EarlyView.Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Unstable simultaneous whirl of two cylinders in a concentric double rotating cylinder system
Mechanical Engineering JournalThis study investigated the unstable simultaneous whirl of two cylinders in a concentric double rotating cylinder system, with both co- and counter-rotation. The axes of both cylinders were radially elastically supported independently of each other.
