  1. 1. Fundamental Study of two Selected Tropical Biomasses for Energy : coconut and cashew nut shells

    Författare :Alberto Júlio Tsamba; Wlodzimierz Blasiak; A. K. Gupta; KTH; []
    Nyckelord :Cashew nut shells; coconut shells; biomass; thermogravimetry; pyrolysis; kinetics; combustion; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning :  Cashew nut and coconut shells are two potential renewable and environmentally friendly energy sources that are commonly found as agro-industrial wastes in tropical countries. Despite this fact, they are not yet widely studied as such. LÄS MER

  3. 2. Pyrolysis profiles and global kinetics of tropical biomass : coconut and cashew nut shells

    Författare :Alberto Júlio Tsamba; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermogravimetry; cashew nut cocnut shells; pyrolysis; kinetics; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Biomass has been recognised as renewable and environmentally friendly source of energy since decades. Tropical biomasses which are available in large quantities as residues in Latin America, Africa and Asia, have high energy potential for exploitation through thermochemical conversion process, as pyrolysis, gasification or combustion.

  4. 3. Beyond average crystal structures: understanding extended and local environments in proton-conducting Sc-substituted BaTiO3 perovskites

    Författare :Nico Torino; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; proton conducting oxide; IR; thermogravimetry; perovskite; neutron scattering; Raman; Reverse Monte Carlo; ordering; BaTiO3;

    Sammanfattning : Proton conducting ceramics are very promising for applications concerned with energy sourcing with cleaner, safer, more abundant and cheaper alternatives to fossil fuels. These materials are still in development and advances in the field depend on a better understanding of the role of defects, their identification and location in the host framework, and the assessment of their short- and long-range dynamics and kinetics.

    Sammanfattning : This thesis investigates sustainability measures for quicklime and cement clinker production. It is the aim of this thesis to contribute to the effort of creating a more sustainable modus of industrial production. LÄS MER

  7. 5. Toward Safer Energy Storage Solution by Development of Fluorine-Free Battery Electrolyte

    Författare :Elham Hosseini Bab Anari; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries SIBs ; aqueous electrolyte; lithium-ion batteries LIBs ; safer electrolyte; fluorine-free salt;

    Sammanfattning : Portable electronic devices such as mobile phones, laptops, cameras and electronic vehicles (EVs) which contain lithium-ion batteries (LIBs), are indispensable part of our modern society. The safety of conventional electrolytes of LIBs, composed of fluorinated lithium salts and organic solvents is the source of some concerns. LÄS MER
