Regulating the absorption spectrum of polydopamine

Polydopamine (PDA) is an advanced functional material and its emergent light absorption properties make it crucial for applications in materials science. However, it is challenging to rationally design and regulate PDA absorption ...

Fish-inspired material changes color using nanocolumns

Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material.

Trisulfur anion helps explain gold deposits on Earth

(Phys.org)—People have been excavating gold for thousands of years as a precious rare metal. Gold is in relatively low abundance in the Earth's crust likely coming from the metallic core and from meteorites. For reasons ...
