Even though atoms and their component parts are incredibly tiny, it's impossible to understand the biggest things in the universe —stars, nebulas, and galaxies — without knowing how these invisible particles behave and interact. Up and atom! Word Generation Science - Introductory Chemistry Concep...
Besides Max von Laue’s experiments, another crucial argument for ending debates over the atomic hypothesis at the beginning of the twentieth century was its role in explaining the Brownian motion. More on the disagreements concerning the atom in the field of chemistry during the nineteenth century...

For classical systems with a continuum of energy levels, the density of states is essentially infinite, meaning any energy is allowed in a given energy range. However, for quantum systems, such as atoms and molecules with a discrete energy manifold, the density of states is finite. This begs...
In addition, polymer brushes can be used to generate the Janus character without the intrinsic particle composition or particle core being of the Janus type (Fig. 8.1A) [38,40–44]. In fact, in addition to particles of the Janus type in the strict meaning of the term, being composed of...

However, most assume a fixed fractal dimension, meaning that the structure of the flocs is preserved throughout the process, which is not generally the case. In many cases, the measured flocculation kinetics show that particles are added to structures that increase in size until they reach a ...
Osmosis refers to the movement of fluid across a membrane in response to different concentrations of solute on the two sides of the membrane. The word “osmosis” originates from the Greek, meaning “thrust” or “impulse.” Pfeffer also observed that the flow was proportional to the sucrose ...
