28-Jun-19 First NMR data added to the Database of Zeolite Structures
   

29Si MAS NMR spectra on some pure silica zeolites have been added to the database. Darren Brouwer and his students have been busy combing the literature for suitable spectra, digitizing these spectra, and performing a simple deconvolution. That information along with peak assignment (when available), references and experimental conditions has been inserted into the database structure by Christian Baerlocher, and now we can all enjoy the fruits of their hard work.

    So far, 18 spectra have been included and more will come as time permits.

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!
