Colloids are defined as any particle that is between 1 nanometer and 1 micrometer in diameter and can consist of mineral material and clays, microbes, and decayed plant matter. Due to their small size ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

There is growing evidence for the kinetics of homogeneous nucleation being a multi-step process. Colloid experiments and simulations now suggest that heterogeneous nucleation is no exception. You have ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
