Nanoscale Bubbles can Have a Large Impact on Medical Ultrasound Imaging

If you were given "ultrasound" in a word association game, "sound wave" might easily come to mind. But in recent years, a new term has surfaced: bubbles. Those ephemeral, globular shapes are proving useful in improving medical imaging, disease detection and targeted drug delivery. There's just one glitch: bubbles fizzle out soon after injection into the bloodstream.

New Technology Helps Improve Performances of Fiber Optoelectronic Components

Advances in wearable devices have enabled e-textiles, which fuse lightweight and comfortable textiles with smart electronics, and are garnering attention as the next-generation wearable technology. In particular, fiber electronic devices endowed with electrical properties, while retaining the specific characteristics of textiles, are key elements in manufacturing e-textiles.

Engineering the Boundary Between 2D and 3D Materials

In recent years, engineers have found ways to modify the properties of some “two- dimensional” materials, which are just one or a few atoms thick, by stacking two layers together and rotating one slightly in relation to the other.
