Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Influence of an Al‐Doped ZnO Interface Layer on the Thermochromic Properties of VO2 Thin Films Deposited by RF Magnetron Sputtering

open access: yesAdvanced Engineering Materials, EarlyView.
Herein the metal‐to‐insulator transition is investigated when depositing vanadium dioxide (VO2) on glass or aluminum‐doped zinc oxide (AZO). O2 flow tuning during the deposition and additional post annealing are effective to control the metal‐to‐insulator transition. However, the VO2/AZO/glass stack reveals an increase in the transition temperature and

Effects of the institutional change based on democratization on origin and diffusion of technological innovation [PDF]

open access: yesarXiv, 2020
Political systems shape institutions and govern institutional change supporting economic performance, production and diffusion of technological innovation. This study shows, using global data of countries, that institutional change, based on a progressive democratization of countries, is a driving force of inventions, adoption and diffusion of ...

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams

open access: yesAdvanced Engineering Materials, EarlyView.
The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.
