    University dissertation from Sundsvall : Mid Sweden University

    Author : Thomas Öhlund; Håkan Olin; Hans-Erik Nilsson; Mattias Andersson; Patrick Gane; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; inkjet printing; silver nanoparticles; paper; flexible substrates; sintering; printed electronics; IPL sintering; flash sintering; copper films; coatings; thin films; AgNP; conductive films; metal films;

    Abstract : A new manufacturing paradigm may lower the cost and environmental impact of existing products, as well as enable completely new products. Large scale, roll-to-roll manufacturing of flexible electronics and other functionality has great potential. READ MORE

  2. 2. Liquid-Phase Exfoliation of Two-Dimensional Materials Applications, deposition methods and printed electronics on paper

    University dissertation from Sundsvall : Mid Sweden University

    Author : Viviane Forsberg; Magnus Norgren; Luis Miguel Pereira Nunes; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molybdenum disulfide MoS2 ; transition metal dichalcogenide TMD ; thin films; inkjet printing; 2D inks; liquid-phase exfoliation; shear exfoliation; printed electronics; organic electronics; PEDOT:PSS; photoresponse; photocurrent; cathodoluminescence;

    Abstract : After the unprecedented success of graphene research, other materials that can also be exfoliated into thin layers, like Transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2), have also become the subjects of extensive studies. As one of the most promising methods for large scale production of such materials, liquid-phase exfoliation (LPE) has also been the subject of extensive research and is maturing as a field to the point that devices using additive manufacturing and printed nanosheets are often reported.

  3. 3. Solution-Processable Conductive Graphene-Based Materials for Flexible Electronics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jie Zhao; Zhi-Bin Zhang; Shi-Li Zhang; Matti Mäntysalo; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Graphene oxide; Silver; Copper; Composite; Conductive inks; Flexible electronics; Printed electronics; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. READ MORE

  4. 4. Recognition of printed Sinhala characters by direction fields

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Hemakumar Lalith Premaratne; [2005]

    Abstract : Although substantial research has been carried out on Optical Character Recognition (OCR) where a printed or a handwritten document of script is read as an image and converted to the editable text format, for various languages during the last 30 years, majority of Brahmi descended south Asian scripts are yet to achieve a commercial OCR system....
