Description: 
Co-authorship suggestions
Please note that single crystal diffraction/model prices do not fluctuate based on effort or time and are not waived even if the diffraction model warrants co-authorship. Should you publish data collected in our center, please acknowledge our facility in your manuscripts or grant applications as follows:
 
This research made use of the Chemical and Biophysical Instrumentation Center at Yale University (RRID:SCR_021738).
 
Dr. Mercado is available to assist with the diffraction components of experiments and review manuscripts. Co-authorship should be considered if:
  1. The structural information in the report is derived primarily from diffraction data and constitutes a significant part of the writing.
  2. The structure determination is non-routine, such as involving variable temperature studies, phase changes, or specialized collection environments.
  3. The final structure required a substantial amount of time and technical expertise. For instance:
    • Problematic twinning or significant disorder in structure refinement.
    • Careful consideration of anomalous dispersion (e.g., absolute stereochemistry).
    • Determination of the model by MicroED.

Center Use Policy

  • Staff mounted samples will be mounted at the convenience of their schedule. 

  • Samples can be submitted on the table outside KCL 3

  • To independently use the single crystal diffractometers, you must meet one of the following subpoints:

    • Completed an instrument orientation workshop held in the CBIC (~4 hour time commitment) 

    • Completed CHEM 511 and 512

    • Completed an equivalent course/training at a different institution with a recommendation from the instructor/instrument manager.

  • Independent access enables X-ray facility use for your own research.

  • Independent use does not enable facility use for you to collect data on behalf of other researchers at Yale.

    • Exceptions are granted on a case-by-case basis.
