CHPC - Research Computing Support for the University

In addition to deploying and operating high performance computational resources and providing advanced user support and training, CHPC serves as an expert team to broadly support the increasingly diverse research computing needs on campus. These needs include support for big data, big data movement, data analytics, security, virtual machines, Windows science application servers, protected environments for data mining and analysis of protected health information, and advanced networking. Visit our Getting Started page for more information.

Figure 1: Snapshots from simulations of two types of nanomaterials. (a) A highly porous metal-organic framework (ZIF-8), consisting of Zn ions (yellow spheres) and methylimidazolate linkers (nitrogen atoms are colored blue, carbon atoms are colored gray, hydrogen atoms are not shown). (b) A superstructure formed from octahedral silver nanocrys- tals. The pink frame indicates the boundaries of the simulated region. A few nanocrystals are colored yellow and blue to highlight features of the complex structure they form.

Watching Nanomaterials Assemble at CHPC

By Prof. Michael Grünwald, Department of Chemistry 

My son and I like to build remote control cars. The path that leads from a disordered pile of plastic parts and metal screws to a ne race car is straightforward and fun: step after step, we collect the pieces that need to be assembled and put them together according to the instructions. In fact, this assembly strategy is the blueprint for much human building activity and applies almost generally to the con- struction of houses, machines, furniture (in particular the Swedish kind), and many other objects of our daily lives.

Large objects, that is. Building small things, as it turns out, requires a strikingly different approach. Consider, for in- stance, the “objects” illustrated in Figure 1: A porous crys- tal structure made from intricately arranged metal ions and organic molecules (a “metal-organic framework”), and an ordered arrangement of nanoparticles (a “superstructure”), which themselves consist of many thousands of atoms. These structures are examples of “nanomaterials”, objects that derive their unusual properties from their fascinating microscopic structure. Because of their large pores, metal- organic frameworks like the one in Figure 1a can be used to store hydrogen gas, lter CO2, or separate molecules by shape. Depending on the kinds of nanoparticles used, superstructures such as the one in Figure 1b can be used to alter the direction of light, or act as new kinds of solar cells.
