Researchers turn coal powder into graphite in microwave oven

Using copper foil, glass containers and a conventional household microwave oven, researchers have demonstrated that pulverized coal powder can be converted into higher-value nano-graphite.

A better pen-and-ink system for drawing flexible circuits

Scientists have developed inexpensive conductive inks for clog-free ballpoint pens that can allow users to 'write' circuits almost anywhere -- even on human skin.

Physicists observe competition between magnetic orders

Researchers have used ultracold atoms to gain new insights into previously unknown quantum phenomena of 2D materials. They found out that the magnetic orders between two coupled thin films of atoms compete with each other.

A breakthrough manufacturing process of ultra-thin sensor for smart contact lenses

Smart contact lenses could soon become mainstream thanks to a new manufacturing process that has allowed researchers to develop a multifunctional ultrathin sensor layer.
