MD simulations reveal chaos in electron transport

Using Martini, we were able to simulate the spontaneous binding and unbinding of electron carriers to photosystem II, one of the key protein complexes in photosynthesis. For more details, please see the full paper:

Martini Solar Cells

Martini is also suited for non-biological applications. Check out our latest work on bulk heterojunction morphologies for organic solar cells. Mixtures of poly(3-hexyl-thiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM), solvated in chlorobenzene, slowly dried and cooked to perfection !

Polarizable water model

A refined polarizable water model is now available, developed by the group of Jens Smiatek. The new model improves the behavior of Martini with long range electrostatic interactions. Available from the download section. See: J. Michalowsky, L.V. Schäfer, C. Holm, J. Smiatek. http://dx.doi.org/10.1063/1.4974833 for details.
