1. 11. Light-Emitting Electrochemical Transistors

   Författare :Jiang Liu; Magnus Berggren; Isak Engquist; Qibing Pei; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Since the discovery of conductive polymers in 1977, the implementation of organic conjugated materials in electronic applications has been of great interest in both industry and academia. The goal of organic electronics is to realize large-area, inexpensive and mechanically-flexible electronic applications. LÄS MER

3. 12. Electrochemical Capacitors for Miniaturized Self-powered Systems

   Författare :Qi Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Electrolyte materials; Electrochemical capacitors; AC line filters; Energy storage; Miniaturized self-powered systems; Electrode materials;

   Sammanfattning : Miniaturized self-powered systems with harvest-store-use architectures have been recognized as a key enabler to the internet-of-things (IoT), and further the internet-of-everything (IoE), 5G communication and tactile internet. Electrochemical capacitors (ECs), also known as supercapacitors, are promoted to be the energy storage component in such systems, because of their advantages such as an almost limitless cycle life that is ideal for the vision of “fit-and-forget” maintenance-free networks.

4. 13. Electrochemical Application and AFM Characterization of Nanocomposites : Focus on Interphase Properties

   Författare :Hui Huang; Per Claesson; Orlando Rojas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrochemical sensor; nanocomposite; graphene; carbon nanotubes; phytic acid; polyaniline; corrosion protection; silica nanoparticles; atomic force microscopy; interphase; Kemi; Chemistry;

   Sammanfattning : The use of graphene and conductive polyaniline nanomaterials in the field of electrochemistry is increasing due to their excellent conductivity, rapid electron transfer and high specific surface area. However, these properties are strongly dependent on the preparation processes. LÄS MER

5. 14. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques

   Författare :Marie Långberg; Jinshan Pan; David Lindell; Ulf Kivisäkk; Edvin Lundgren; Sannakaisa Virtanen; KTH; []
   Nyckelord :Passive film; duplex stainless steel; synchrotron X-ray reflectivity; X-ray diffraction; X-ray fluorescence; hard X-ray Photoelectron emission microscopy; X-ray Photoelectron spectroscopy; Electrochemical impedance; Kemi; Chemistry;

   Sammanfattning : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. LÄS MER

7. 15. Electrochemical investigations on lipid cubic phases

   Författare :Mohammad Yaser Khani Meynaq; Britta Lindholm-Sethson; Solomon Tesfalidet; Ehud M. Landau; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

   Sammanfattning : Electrochemical Impedance Spectroscopy (EIS) was used to develop a novel methodology for studying ionic interaction with lipids arranged in a lipid cubic phase (LCP). Studying different types of ions, both cations and anions, validated the method. LÄS MER
