Interfacial Dissipative Phenomena in Tribomechanical Systems
Dear Colleagues,
In the last twenty years, tribology and nonlinear dynamics have included several major contributions related to key topics such as rough contact, friction, damping mechanisms, and dynamical behaviour of nonlinear systems, which are paving the way for future engineering challenges. The two fields are largely intertwined as, among the others, contact nonlinearities are almost omnipresent in any technical application ranging from the development of NEMS/MEMS to bioengineering, automotive, civil/mechanical industry, and aerospace.
USACM Virtual Seminar by John Evans, UC Boulder

We have a number of seats available to anyone interested. We just ask attendees to register at this page:
Deformation Mechanisms in Gold Nanoporous
Our recent work on nanoporous gold addresses defrmation mechanisms in nanoporous gold through molecular dynamics simulations, proposing the use of load transfer between nanopores for biosensing applications.

Honeycomb Nanoporous Silicon with Magic Properties
Our recent study through molecular dynamics simulations represents a new approach to improve the mechanical behaviour of nanoporous silicon through controlling the pore shape. In this work, a high strength and ductile structure is obtained for honeycomb nanoporous strucutres.

Freeze casting of novel materials
Freeze casting presents exciting new avenues towards high performance materials with aligned pore structures.
Bone scaffolds, highly elastic composites and nacre mimetic materials can all be produced by means of freeze casting methods.
This comprehensive review presents recent development in terms of materials and processing
Hard-magnetic Elastica
Stroke is #1 cause of long-term disability and #4 cause of death in the US. Most of the patients are not treated in time due to unavailability of professional neurosurgeons on site. We have developed a ferromagnetic soft continuum robot for tele-operated and autonomous navigation and treatment of strokes. The foundation is the hard-magnetic elastica theory which offers a fast and accurate prediction of the large deformation of the ferromagnetic soft continuum robot.
