Agricultural food production and consumption covers activities ranging from agriculture to food consumption. Pollution and food contamination related to the use of production technologies and processes, as well as from the use of products aimed at increasing agricultural yields and facilitating food conservation, have significant environmental consequences. There are a number of important issue...

Majority of materials employed for food packaging are non-biodegradable materials which do not meet increasing demands in society for sustainability and environmental safety. Thus, numerous biopolymers have been exploited to develop biodegradable food packaging materials. Nonetheless, the usage of biopolymers has been limited due to the poor mechanical and barrier properties. These properties c...

Information on how cells interface with nanomaterials in biological environments has important implications for the practice of nanomedicine and safety consideration of nanomaterials. However, our current understanding of nanobiological interactions is still very limited. Here, we report the direct observation of nanomaterial bio-complex formation (other than protein corona) from nanomaterials ...

In this paper, a novel robust tracking control law is proposed for constrained robots under unknown stiffness environment. The stability and the robustness of the controller are proved using a Lyapunov-based approach where the relationship between the error dynamics of the robotic system and its energy is investigated. Finally, a 3DOF constrained robotic arm is used to prove the stability, the ...
