Simulación del comportamiento elastoplástico de estructuras bifásicas policristalinas de aceros “Dual-phase”

Boletín de la Sociedad Española de Cerámica y Vidrio, 2000
In order to model the elasto-plastic behaviour of polycrystalline dual-phase steel microstructures (ferrite/martensite), uniaxial tension is simulated using a 3-D finite element code.

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

Advanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Assurring microstructural homogeniety in dual phase and trip steels

, 2004
The presence of ferrite/pearlite bands in dual phase and TRIP assisted steels is a consequence of micro-chemical segregation which causes mechanical properties anisotropy.

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

Advanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Unlocking Exceptional Strengthening in Aluminum Alloys via Interstitial Cottrell Atmosphere Formation

Advanced Functional Materials, EarlyView.
Cyclic unloading‐aging‐reloading micro‐tensile tests under various aging durations and temperatures, combined with comprehensive microstructural characterization reveal that the yield point phenomenon in Aluminum‐Carbon (Al‐C) thin films originates from Cottrell atmosphere formation.
