Summary of "Two-dimensional materials with intrinsic auxeticity: progress and perspectives."

Materials with a negative Poisson's ratio, termed auxetic materials, will expand (contract) in the transverse direction when they are stretched (compressed) longitudinally. They provide exciting prospects for enhancing mechanical properties and a wide range of promising applications. Driven by the current demand for nano-devices with specific functionalities, research studies on two-dimensional auxetic materials with an intrinsic negative Poisson's ratio are intensively simulated. Herein, we summarize the recent efforts and progress in material discovery and property characterization on two-dimensional auxetic materials. We categorize the rich variety of the proposed two-dimensional auxetic materials based on their structures and whether they have been synthesized experimentally. The underlying mechanisms for forming a negative Poisson's ratio as well as the modulation of negative Poisson's ratio are discussed. Finally, we close by assessing the challenges and perspectives faced by future research and development of this compelling class of materials.

Medical and Biotech [MESH] Definitions

Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)

The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.

The transport of materials through a cell. It includes the uptake of materials by the cell (ENDOCYTOSIS), the movement of those materials through the cell, and the subsequent secretion of those materials (EXOCYTOSIS).

An interdisciplinary study of the microstructure and composition of various materials such as metals, semiconductors, ceramics, and polymers, in relation to their macromolecular physical and chemical properties.
