A bizarre "Rule of Four" has been identified in the basic structure of the majority of inorganic materials—and scientists are stumped as to why. The pattern is found in the so-called "unit cell" of ...

The image taken with a scanning electron microscope shows a complex material system consisting of chitosan and nanocellulose. The chitosan scaffold was freeze casted with a cooling rate of 10 ° C/min.

Mesoporous materials are a class of nanomaterials characterized by their highly ordered porous structure with pore sizes ranging from 2 to 50 nanometers. These materials possess large surface areas, ...
