  1. 1. Persian Orthography Modification or Changeover? (1850-2000)

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Forogh Hashabeiky; Uppsala universitet.; [2005]
    Keywords : HUMANIORA; HUMANITIES; Iranian languages; Persian; Persian orthography; Arabic alphabet; modification; changeover; romanization; orthographic conventions; bound and unbound writing; Iranska språk - allmänt; Iranian Languages; Iranska språk;

    Abstract : The present study provides a description of the standardization process of Persian orthography since the introduction of the Arabic alphabet, with a focus on this process in modern times (1850-2000). Using theories related to orthography standardization as its background, this work seeks an explanation for the prolonged standardization process of Persian orthography, and presents the frameworks within which this standardization has been carried out.

  5. 5. Modification of zeolites and synthesis of SAPO-templated carbon

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Yunxiang Li; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microporous material; zeolite; SAPO templated carbon; hydrothermal synthesis; CVD; post modification; direct modification; snowflake; materialkemi; Materials Chemistry;

    Abstract : Zeolites are crystalline aluminosilicates with diverse structures and uniform porosities. They are widely used as catalysts, adsorbents and ion-exchangers in industry. Direct or post modifications optimize the performance of zeolites for different applications. In this thesis, IZM-2 and TON-type zeolites were synthesized, modified and studied. READ MORE
