Applications are invited for an immediate  postdoctoral position within the Marine Additive Manufacturing Centre of Excellence at the University of New Brunswick. The candidate will perform research in the area of materials characterization of additively manufactured metals (aluminum or steels) developed through powder bed fusion techniques. The candidate will use several experimental techniques to characterize the 3D printed metals such as OM, SEM, EBSD measurements, fractography, and TEM.

Our recent review paper on how origami and kirigami techniques that could be used to create curved geometries has been just publised online. It is available as an open access article, which is why I am posting it here. We have also included some beautiful photos of our hand-folded origami and kirigami.

“Metamaterials” are the fabled materials exhibiting properties and functionalities that defy expectations. Or at least that's how I have always defined them to myself. These first emerged on the scientific scene in the nineties; or perhaps that is when an extensive flurry of activities on this subject can be traced to. The initial focus was on designing (what appeared to me as) composites with a specific geometrical inner structure that allowed the emergence of electromagnetic properties not typically seen in nature; such as negative refractive index.

The Institute of Mechanical Engineering is soliciting applications for a faculty position at the level of tenure-track assistant professor in Thermal Sciences.

I do not think in Imechanica there has been an obituary for Paul Paris, whose work in fatigue crack propagation is extraordinary and one of the few important and lasting contributions ----- today our aircrafts, both civil and military, all rely on "damage tolerance", which is based on Paris' law.   Paris' law, as every great innovations, was published in 1961 only after rejection by three of the leading journals in the fracture mechanics field.  It bears the name of "law" although of course it is not like Newton's law.  It is a power law, based perhaps on what Baren

The School of Mechanical and Mechatronic Engineering at the University of Technology Sydney is seeking PhD students to work on projects related to:

a) Energy Harvesting: harnessing renewable energy from wind, vibration, human motion, ocean wave, etc.

b) Smart Materials and Structures: adaptive structures with composite materials, smart materials (piezoelectric/flexoelectric/triboelectric/magnetorheological,etc) for energy conversion and vibration control; acoustic metamaterials

A fulltime researcher is sought for an open research position effective immediately. Research project is in the field of biomimetics – fabrication of bioinspired surfaces for water collection and repellency. Project involves microfabrication of surfaces using various coating composites and characterization as well as some modeling.
