Dual-phase nanostructuring as a route to high-strength magnesium alloys, Wu, Chan, Zhu, Sun, Lu, Science, 2017

Novelty/impact/significance:

Create a magnesium-based supra-nanometer-sized dual-phase glass-crystal (SNDP-GC) material that approaches the near-ideal strength, 3.3 GPa and a Young’s modulus of 65 GPa. The fabrication is easy to scale up (magnetron sputtering) and the material is 10cm x 10cm with 10 µm in thickness, which is promising for various industrial applications.

Scientific question:

The IRDS analytics lab (https://alouhghalam.sites.umassd.edu) at the University of Massachusetts Dartmouth (UMassD) has a fully-funded PhD position. The graduate student will be working on an exciting project related to the dynamics of locally resonant structures and machine learning techniques with application to source localization. This position will involve working closely with a multidisciplinary team from UMassD, UMass Lowell and NUWC.

Heterogeneous lamella structure unites ultrafine-grain strength with coarse-grain ductility, Wu, Yang, Yuan, Wu Wei, Huang, Zhu, PNAS, 2015

Novelty/impact/significance:

A novel heterogeneous lamella structure in Ti is created, which is as strong as the ultrafine-grained Ti and simultaneously as ductile as the coarse-grained Ti, with higher strain hardening than the coarse-grained Ti.

Hello again iMechanica! My name is Ryan and I am the Founder of Mechanical Engineering HQ. I am writing today to share an interesting development in water sanitation technology. Scientists and engineers have developed a new solar powered water purifier that can create drinking water from wastewater and seawater. Read on to find out how they have achieved this!
