    Sammanfattning : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.

  3. 7. Organic Bioelectronics : Electrochemical Devices using Conjugated Polymers

    Författare :Joakim Isaksson; Magnus Berggren; Ananth Dodabalapur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Since the Nobel Prize awarded discovery that some polymers or “plastics” can be made electronically conducting, the scientific field of organic electronics has arisen. The use of conducting polymers in electronic devices is appealing, because the materials can be processed from a liquid phase, much like ordinary non-conducting plastics. LÄS MER

  4. 8. Mesostructured materials : Synthesis towards applications

    Författare :Nina Andersson; Osamu Terasaki; Peter Alberius; Anders Palmqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : A new class of materials with well-defined structures on mesoscopic (2-50 nm) length scales has attracted considerable interest during the last decade. These mesostructured mataterials are formed from the self-assembly of amphiphillic molecules and inorganic precursors. LÄS MER

  5. 9. Functionalization of Synthetic Polymers for Membrane Bioreactors

    Författare :Hamidreza Barghi; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioreactor; Functionalization; Hydrophilic; Membrane; Polyamide 46; Synthetic polymer; Resursåtervinning; Resursåtervinning; Resource Recovery;

    Sammanfattning : Membrane bioreactors (MBRs) show great promise for productivity improvement and energy conservation in conventional bioprocesses for wastewater reclamation. In order to attain high productivity in a bioprocess, it is crucial to retain the microorganisms in the bioreactors by preventing wash out. LÄS MER

  7. 10. Organic functionalization of graphene for applications in energy storage devices and optoelectronics

    Författare :Cheng Peng; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene; aqueous energy storage; optoelectronics; organic functionalization; 2D materials;

    Sammanfattning : The emergence of one-atom layer thick materials, exemplified by graphene following its first exfoliation by Geim and Novoselov, has sparked significant research interest. Owing to their unique electronic structure, 2D materials are regarded as promising candidates for diverse applications, including field-effect transistors (FETs), solar energy harvesting, biological systems, water purification, and energy storage devices.
