This tutorial launches a short series introducing data structures and algorithms. In Part 1, you’ll learn what a data structure is and how data structures are classified.

Heterogeneities in space and time Figure 1 illustrates the complexity of heterogeneous catalysts at different length- and timescales for the two types most often used in industrial processes.

Scientists develop a means of creating 'hopfion' crystals, complex, knot-like patterns of light that repeat across both space and time.
