Abstract: Abstract The design of morphing structures requires attaining concurrently light-weight, load-carrying and shape adaptable systems that minimize complexity, actuation requirements and part count. Exploiting the external loads to produce local stiffness variations induced by elastic… read more here.

DOI: 10.1016/j.pnucene.2018.09.013
Abstract: Abstract Provided fluid velocity reaches a specific threshold value, the vibrational amplitude of the corresponding structure increases rapidly and becomes unstable. Even though nuclear industrial concerns have been focused primarily on heat exchangers, steam generators… read more here.

DOI: 10.1021/acsnano.2c02799
Abstract: Many crystallization processes, including biomineralization and ice-freezing, occur in small and curved volumes, where surface curvature can strain the crystal, leading to unusual configurations and defect formation. The role of curvature on crystallization, however, remains… read more here.
