In this paper, a computational hierarchical multiscale method is presented to investigate the effect of temperature on mechanical behavior of heterogeneous nanomaterials. The embedded-atom method many-body interatomic potential is employed to investigate the complex interaction between the atoms of copper–aluminum (Cu-Al) alloy at various temperature levels. The thermo-mechanical properties of Cu-Al alloy are studied at various percentages of Cu-Al. The Nose-Hoover thermostat is proposed for the molecular dynamics analysis.

We have one postdoc position on soft matter tribology (focused on theory and simulations) at the Italian Institute of Technology (IIT) in Lecce, Italy (Center for Biomolecular Nanotechnologies, CBN, https://cbn.iit.it/). The activities will be performed in strict collaboration with the University of Salento, located in the same city, as well as with an international industrial partner. The salary is highly competitive and depends on scientific skills.

ABSTRACT: Cell migration is essential for regulating many biological processes in physiological or pathological conditions, including embryonic development and cancer invasion.

I hope some of you will find this work interesting. We present a new Weibull framework for cleavage fracture that incorporates strain gradient plasticity and can estimate the three parameters of Weibull-type models without any prior assumptions. A post-print is available at www.empaneda.com

The programmable shape transition of a two dimensional sheet to a three-dimensional (3D) structure in response to a variety of external stimuli has recently attracted increasing attention. Among the various shape changing materials, shape memory polymers (SMPs) can fix their temporary shape and/or their length and recover under proper thermal treatment.

Many living organisms undergo conspicuous or abrupt changes in body structure, which is often accompanied by a behavioral change. Inspired by the natural metamorphosis, robotic systems can be designed as reconfigurable to be multifunctional. Here, a tissue-engineered transformable robot is developed, which can be remotely controlled to assume different mechanical structures for switching locomotive function.
