Predicción de vida a fatiga por fretting incluyendo tensiones residuales

, 2010
This paper analyzes the behaviour of laser and shot-peened specimens subjected to fretting fatigue tests. The material was aluminium Al 7075-T651 and the contact pads had a spherical geometry. Fretting fatigue life is estimated taking into account the residual stress induced by the laser and shot-peening treatments and its relaxation during the test ...

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

Advanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

Advanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Dispensing Volumetric Additive Manufacturing

Advanced Functional Materials, EarlyView.
Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Distribución y evolución de tensiones residuales en materiales compuestos de matriz metálica [PDF]

, 2017
El objetivo de este trabajo es alcanzar, desde un punto de vista experimental, un conocimiento más profundo del modo en que las tensiones residuales, generadas por temple, se distribuyen a lo largo de un material y evolucionan con tratamientos termo-mecánicos.

BACH, a Bayesian Optimization Protocol for Accurate Coarse‐Grained Parameterization of Organic Liquids

Advanced Functional Materials, EarlyView.
We present a fully automated Bayesian optimization (BO) protocol for the parameterization of nonbonded interactions in coarse‐grain CG force fields (BACH). Using experimental thermophysical data, we apply the protocol to a broad range of liquids, spanning linear, branched, and unsaturated hydrocarbons, esters, triglycerides, and water.

Medición de tensiones residuales

, 2015
El present projecte tracta sobre les tensions residuals, les quals son molt a tenir en compte en enginyeria, ja que sovint són una causa de fallada prematura dels components crítics d'estructures, maquines, etc. No obstant, en algunes ocasions es possible beneficiar-se de les tensions residuals, quan aquestes son a compressió.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
