The call for functional materials and sustainable devices has become a long-standing priority on the agendas of many countries around the world. One class of these materials comprises metamaterials and architected or functional materials, which are characterized by having properties and functions planned and programmable. Examples include the development of smart medicines, wearable devic…
Some materials are special because of their special, different, not intuitive, unexpected, exceptional, surprising properties. Graphene is a known example due to its combination of very spcial physical properties. Auxectic materials that expand (contract) when stretched (compressed) are also examples of special materials. Not only the graphene, which reminds us about the interesting prope…
The advancement of experimental techniques is allowing the production and manipulation of different types of materials at the nanoscale with great precision. This motivates the search for new functional materials to fulfill a large number of scientific and technological challenges. In particular, modeling and computer simulations in the reasearch on new materials provide two important con…
The special properties of nanomaterials will not be useful if they cannot be transfered to macroscopic devices and applications. The research on nanostructured materials aims to fulfill this purpose. There are two forms to produce nanostructured materials: combining several nanostructures to build 2D or 3D materials, or mixing nanostructures with matrices to form composites. This project …

In 2021, a paper published in Nature reported the findings of a study on two-dimensional polycatenated materials, the stiffness of which was controlled by pressure. A recent preprint from the same research group reported the results on three-dimensional polycatenated metamaterials (PAMs), which have since been published in the January 17, 2025, issue of Science. These materials are formed…
Auxetic structures are defined as those that possess a property referred to as negative Poisson's ratio (PR). The PR is defined as the ratio between the lateral and longitudinal deformations in a material under the action of a longitudinal stress. Consequently, auxetic materials are characterized by an inherent tendency to undergo expansion (or contraction) when subjected to tensile (or c…
Two-dimensional materials, or simply "2D", are defined as one-atom-thick crystalline solids characterized by two types of physicochemical interactions: i) short-range or covalent bonds in the two-dimensional plane of the structure and ii) long-range van der Waals-type bonds between adjacent layers of the structure. Even 20 years after the publication of Novoselov and Geim's seminal paper …
Filaments of different sizes have a similar and universal behavior when subjected to large torsional stresses. When their ends are kept fixed or connected one to each other forming a closed filament, these structures can undergo a phenomenon of topological transformation known as twist to-writhe conversion (TWC). This transformation consists of the formation of contortions or helical turn…
One of actual challenges in science and technology is the development of more efficient methods to provide refrigeration that do not harm nature. Applications range from heat dissipation in electro-electronic devices, to air conditioning and food refrigeration. The increasing trends towards miniaturization of technological devices had stimulated research on new forms of refrigeration at t…
Origami is an old Japanese art of folding. Although well studied in its geometrical aspects, origami structures have been, recently, considered in applications in Engineering because of their discovered special mechanical properties. Due to the great interest in building 3D nanostructures, there are several studies of how to make nano-origamis (NOs) from combinations of 1D and 2D nanostru…

It is known that the properties of materials are directly related to their chemical composition and their micro and nanostructures. In general, man-made materials and structures are formed by combinations of periodic networks and/or geometric patterns. These materials are called regular or regular micro and nanostructures. However, the scientists' perception that the microstructure of man…
It is well known that technology reached the nanoscale. This is mainly the consequence of the very special physical properties of materials at nanoscale. At this scale, one system possesses from milion to bilion of atoms and the quickly growth of the computational capacity is allowing the numerical simulation of some physical properties of these systems directly from the dynamics of their…
