3. 2. Functionalization and processing of porous powders into hierarchically porous monoliths

   Författare :Petr Vasiliev; Lennart Bergström; Yoshio Sakka; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porous; zeolite; hierarchical; monolith; nanoparticle; functionalization; amorphization; PCP; SPS; pulsed current processing; spark plasma sintering.; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Inorganic porous materials are widely used in a number of applications, where is a need to functionalize and produce materials with a multiscale porosity. The first part of the thesis describes how a novel and facile powder processing approach, using pulsed current processing (PCP) or, as it is commonly called, spark plasma sintering (SPS), has been employed to produce mechanically stable, hierarchically porous bodies from different porous powders.

4. 3. Synthesis and Synchronization Support for Hierarchically Scheduled Real-Time Systems

   Författare :Mikael Åsberg; Thomas Nolte; Neil Audsley; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

   Sammanfattning : A piece of software, that we define as a software system, can consist of anything from a few lines of program code or the entire software stack in a vehicle. Software systems can be divided into smaller and partially independent parts called subsystems/partitions (we use the words partition and subsystem interchangeably). LÄS MER

5. 4. Var är meningen? : Elevtexter och undervisningspraktiker

   Författare :Ewa Bergh Nestlog; Gunilla Byrman; Ellen Krogh; Synnøve Matre; Linnéuniversitetet; []
   Nyckelord :HUMANIORA; HUMANITIES; teaching and learning writing; meaning making; pupils’ texts; upper primary school; discursive practice; literacy practice; argumentative text; explanatory text; rhetorical structure theory; relief theory; skrivundervisning; skrivlärande; meningsskapande; elevtexter; mellanstadiet; diskursiv praktik; skriftpraktik; argumenterande text; förklarande text; retorisk strukturteori; reliefteori; Swedish Didactics; Svenska språket med didaktisk inriktning;

   Sammanfattning : This is about how pupils in years 4 to 6 of compulsory school and their teachers make meaning in teaching activities and texts. The aim of the study is to investigate the teaching and learning of writing and the pupils’ discursive texts. LÄS MER

7. 5. Synthesis, characterization and applications of hierarchical porous inorganic materials: a multi-dimensional approach

   Författare :Junzhong Lin; Junliang Sun; Xinwen Guo; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zeolites; Porous material; Hierarchical; Synthesis; Catalysis; MFI zeolite; MWW zeolite; ZSM-5; TS-1; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Zeolites are a type of microporous crystalline materials that have been widely used in industrial applications including separation, adsorption, and catalysis. However, great limitations on diffusion through these materials can arise due to the small pores present in mircoporous frameworks, and this can impact catalytic reactions in particular. LÄS MER
