A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

open access: yesAdvanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Assessment of Omega-3 Fatty Acid Food Intakes in Online Motorcycle Taxi Drivers [PDF]

open access: yes, 2021
Online motorcycle taxi drivers have risk of being exposed to vehicle air pollution, especially with smoking habits. Cigarette smoke can increase lipid peroxidation from PUFA (Polyunsaturated Fatty Acid) by triggering oxidative stress.

Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition

open access: yesAdvanced Engineering Materials, EarlyView.
A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Importance of a balanced omega 6/omega 3 ratio for the maintenance of health: Nutritional recommendations Importancia del equilibrio del índice omega-6/omega-3 en el mantenimiento de un buen estado de salud: Recomendaciones nutricionales

open access: yesNutrición Hospitalaria, 2011
The modification of dietary patterns has led to a change in fatty acid consumption, with an increase in the consumption of ω-6 fatty acids and a markerd reduction in the consumption of ω-3 fatty acids.

A Review of the Effects of Omega-3 and Omega-6 on Alcoholic and Non-Alcoholic Fatty Liver

open access: yes
Non-alcoholic fatty liver disease (NAFLD) is characterized by fat accumulation in the liver not caused by excessive alcohol consumption. In contrast, alcoholic liver disease (ALD) is directly caused by it.

Omega-3 fatty acid supplementation in horses

open access: yes, 2014
Polyunsaturated omega-3 fatty acids (n-3 PUFA) are a family of essential fatty acids with many biological activities. These fatty acids are incorporated into cell membranes, changing their structural and functional characteristics.

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
