News from the Structure Commission

22-Jul-22 At the IZC in Valencia, Spain, the Structure Commission
  welcomed three new members
    Hubert Koller
Junliang Sun
Tom Willhammar
  and thanked three retiring members for their service
    Mike Anderson (2016-2022)
Russell Morris (2004-2022)
Stef Smeets (2019-2022)
28-Jun-22 Two new Framework Type Codes have been approved
  JZO Type material: ZEO-1
        Lin, Q.F., Gao, Z.R., Lin, C., Zhang, S., Chen, J., Li, Z., Liu, X., Fan, W., Li, J., Chen, X., Camblor, M.A., Chen, F.J.
          "A stable aluminosilicate zeolite with intersecting three-dimensional extra-large pores"

          "EMM-25: the structure of two-dimensional 11x10 medium-pore borosilicate zeolite unraveled using 3D electron diffraction"

24-Jun-22 Dealing with Disordered Zeolite Framework Structures
    Zeolite materials with disordered framework structures cannot be described properly within the layout of the Database of Zeolite Structures, because that layout assumes that the framework structures are perfectly ordered in 3 dimensions. In view of the fact that there are an increasing number of such zeolites, a second database, designed specifically to describe such materials, has been created and integrated into the Database of Zeolite Structures under the tab Intergrowths. These frameworks are not assigned 3-letter codes, but are grouped into Intergrowth Families that share a common Periodic Building Unit (PerBU) that can be connected in different ways.

The hard work has been done by
Christian Baerlocher: project coordination, structure of the database, construction of webpages
Lynne McCusker: creation of images for the connectivity patterns and the polymorphs
Hermann Gies: simulation of XRD powder patterns for intergrowth series using DIFFaX
Bernd Marler: providing the measured powder patterns and input for the disorder examples

The database is still under development, but a first version has now been uploaded and made available to the zeolite community.

Corrections, comments, suggestions and other feedback are welcome, and should be sent directly to Christian Baerlocher.

22-Mar-21 Francis Taulelle (1951-2021)
  It is with great sadness that we must report that one of our members, Prof. Francis Taulelle, passed away on February 17, 2021.

His experience in the application of modern NMR techniques to address subtleties in zeolite structures was a valuable addition to the expertise of the Structure Commission, and his input will be sorely missed. Indeed it was his enthusiasm for combining different techniques to solve scientific puzzles that led to the SMARTER conference series that started in 2007 in Aveiro, Portugal. He was passionate about looking at the larger picture, and encouraging scientists from different fields to collaborate to achieve this goal.

Francis' took great pleasure in scientific discussions, often contributing unusual ideas and questions. We are all saddened that we will not be able to continue these animated discussions with him in the future.

15-Aug-17 The Database of Zeolite Structures continues to develop
Several features have been added to the database recently:

      The origin of the type material name and the derivation of the associated three letter code has been added to the Type Material page.

      The number of topologically distinct T-atoms in the idealized framework structure has been added as a search option on the Advanced Search/Channel System page.

      The dropdown menus now work on mobile devices as well.

    Older framework drawings are being replaced by newer ones as time permits (42 done so far).

  Many thanks to our users for the suggestions and to our Database guru Christian Baerlocher for their implementation!
