  • Design of organic structure directing agents to control the synthesis of zeolites for carbon capture and storage 

    Daeyaert, Frits; W. Deem, Michael (2019)
    We have de novo designed organic structure directing agents (OSDAs) for zeolites that have been predicted to be effective materials for carbon capture and storage. The zeolites were selected for their reduced parasitic energy when used as CO2 adsorbants in a pressure–temperature swing process in coal- or natural gas-fired power plants. Synthetically ...

  • First Results on the Scalar WIMP-Pion Coupling, Using the XENON1T Experiment 

    XENON Collaboration (2019)
    We present first results on the scalar coupling of weakly interacting massive particles (WIMPs) to pions from 1 t yr of exposure with the XENON1T experiment. This interaction is generated when the WIMP couples to a virtual pion exchanged between the nucleons in a nucleus. In contrast to most nonrelativistic operators, these pion-exchange currents can ...
