  • Comparing voting methods for budget decisions on the ASSU ballot Gelauff, L. L., Sakshuwong, S., Garg, N., Goel, A. Stanford University. Stanford, CA. 2018


    During the 2018 Associated Students of Stanford University (ASSU; Stanford’s student body) election and annual grants process, the Stanford Crowdsourced Democracy Team (SCDT) ran a research ballot and survey to develop insights into voting behavior on the budget component of the ballot (annual grants) where multiple grant requests (hereafter: ‘projects’) are considered. We provided voters with additional voting methods for the budget component, collected further insights through a survey and demonstrated the viability of the proposed workflow.

  • A molecular cage of nickel(II) and copper(I): a [{Ni(L)(2)}(2)(CuI)(6)] cluster resembling the active site of nickel-containing enzymes CHEMICAL COMMUNICATIONS Angamuthu, R., Gelauff, L. L., Siegler, M. A., Spek, A. L., Bouwman, E. 2009: 2700–2702


    A new mononuclear low-spin nickel(II) dithiolato complex, [NiL(2)] (1), reacts with copper iodide to form the hetero-octanuclear cluster [{Ni(L)(2)}(2)(CuI)(6)] (2) with four trigonal-planar CuI(2)S and two tetrahedral CuI(2)S(2) sites; anagostic interactions between the nickel(II) ions and aromatic protons have been demonstrated by variable-temperature NMR studies to pertain in solution.
