A new platform to stretch 2D materials

Wed, 06/17/2020 - 10:27
The electronic and optical properties of 2D materials can be controlled by mechanical deformations of their crystal structure. This route to tailor the properties of materials is called strain engineering and it is a rapidly evolving field of research in nanomaterials. Straintronics, however, is somewhat hampered by technical issues related to the fast and reliable control of the applied strain. Researchers have now developed a versatile and straightforward platform to control the biaxial strain in atomically thin layers.

Bio-inspired sensor systems based on ion transport, not electronics

Tue, 06/16/2020 - 12:31
Many biological systems transmit signals via ions or molecules, whereas man-made sensors are mainly based on electron transport systems, i.e. electronics. The concept of ionic sensory systems is inspired by ion transport in biological systems, which is the movement of ions across a membrane, passively through ion channels or actively through ion pumps. Although sensory systems based on accurate ion transport are still in their early development, recent progress in nano-ionic sensory systems underlines their significant potential.
