Introduction

Electron diffraction is one of the hottest topics in crystallography, gaining momentum in science and industry. The application of electron diffraction in performing nano-crystallography is a disruptive innovation that is opening up fascinating perspectives, particularly for organic compounds required in the fields of chemical, pharmaceutical and advanced materials research.

Purpose of this study

The purpose of this study is to explore how electron diffraction has emerged as an analytical technique in crystallography, and how is it perceived by industrial and academic scientists throughout various industries. 

Organising institutions

This survey is conducted collaboratively by the International Union of Crystallography (IUCr) and ELDICO Scientific Ltd.

Administrative information

The survey will be executed as an online survey. We use Surveymonkey, a proven online survey supplier. The participation will take 15 – 20 minutes to complete.

As a thank you for their participation, respondents will receive a complimentary report of the results. In addition, ELDICO will donate, for each completed survey, 10 USD to the IUCr Education and Outreach Fund or to the Prize Fund for the Gjønnes medal.

Confidentiality

We take confidentiality seriously. Personal and/or demographic data, as well as contact details will be kept separately from the questionnaire. All answers will be treated confidentially. The publication of the results will only refer to compound results. In case qualitative answers will be cited, the originator will not be disclosed.
