Minerals can be key to healing damaged tissue

May 06, 2022 (Nanowerk News) Every species, from bacteria to humans, is capable of regeneration. Regeneration is mediated by the molecular processes that regulate gene expression to control tissue renewal, restoration and growth. A collaboration between researchers in the Department of Biomedical Engineering and the College of Medicine at Texas...

A new age of 2.5D materials

May 06, 2022 (Nanowerk News) Scientists are exploring new ways to artificially stack two-dimensional (2D) materials, introducing so-called 2.5D materials with unique physical properties. Researchers in Japan reviewed the latest advances and applications of 2.5D materials in the journal Science and Technology of Advanced Materials ("Science of 2.5 dimensional materials:...

Intelligent metasurface could revolutionize our lives

May 06, 2022 (Nanowerk News) The manipulation of electromagnetic waves and information has become central to our daily lives. Intelligent metasurfaces have emerged as smart platforms for controlling the wave-information-matter interactions without manual intervention. They evolved from engineered composite materials, including metamaterials and metasurfaces. As a society, we have witnessed...

Self-propelled, endlessly programmable artificial cilia

May 05, 2022 (Nanowerk News) Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and...
