Glowing dyes help scientists see inside the body and diagnose ailments, but they needed a certain type of molecule to improve the imaging depth. They invented a long wavelength near-infrared fluorescent molecule, and it works.
An international team of scientists has developed what may be the first one-step process for making seamless carbon-based nanomaterials that possess superior thermal, electrical and mechanical properties in three dimensions.
First developed in China in about the year A.D. 150, paper has many uses, the most common being for writing and printing upon. Indeed, the development and spread of civilization owes much to paper's use as writing material.
