  1. 1. Extending Access : Perspectives on Business Model Innovation in Water and Sanitation Service Provision

    Författare :Caroline Jennings Saul; Anders Gustafsson; Nina Veflen; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business Innovation; Water business; WASH; Sanitation; Digitalization; Base of the pyramid; Business Administration; Företagsekonomi;

    Sammanfattning : Many organizations are attempting to improve the well-being of people living in poverty, whether it be philanthropic, through offering transformative services, or buying into the doing well by doing good ethos of corporate Base of the Pyramid (BoP) strategies. Some of these efforts are being directed towards extending access to safely managed water and sanitation services to everyone. LÄS MER

  3. 2. Nanocellulose Oxidation - Fundamentals and Application in Hydrogels

    Författare :Saül Llacer Navarro; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sulfate half-ester group; cellulose oxidation; polysaccharide hydrogels; Nanocellulose;

    Sammanfattning : The adaptable surface chemistry of cellulose nanocrystals (CNCs) makes them outstanding; it provides colloidal stability, which is essential for engineering use, to commercially-available CNCs. Colloidal stability is achieved by the bulky negatively-charged sulfate half-ester groups on the surface that it manufactures itself via the use of sulfuric acid. LÄS MER

  4. 3. Role of Sulfate Half Ester Groups on Modifications and Network Formation of Cellulose Nanocrystals

    Författare :Saül Llacer Navarro; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cellulose nanocrystals (CNCs) are nanomaterials with unique mechanical, physical, and chemical properties, which make them suitable as films and foams. To tap into the potential of CNCs and develop materials with tailored properties and a wider range of applications, it is essential to overcome existing challenges. LÄS MER

  5. 4. Multi-Band Multi-Standard CMOS Receiver Front-Ends for 4G Mobile Applications

    Författare :Saul Alejandro Rodriguez Duenas; Ana Rusu; Mohammed Ismail El-Naggar; Erik Bruun; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; LNA; mixer; 4G; Electronics; Elektronik;

    Sammanfattning : The development of the transistor and its continuous down-scaling has allowed during the last decades the appearance of cheap wireless communication systems targeting consumer products. The complexity of these systems has increased dramatically during the last years, mainly fueled by both the Moore law and improvements in communication theory. LÄS MER

  7. 5. Spintronic and Electronic Oscillators for Magnetic Field Sensing and Ising Machines

    Författare :Dagur Ingi Albertsson; Ana Rusu; Johan Åkerman; Saul Rodriguez Duenas; Atila Alvandpour; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spintronic Oscillator; Behavioural Modeling; Macrospin Approximation; Magnetic Field Sensor; Ising Machine; Duffing Oscillator; Kuramoto Model; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Oscillators can exhibit a range of complex dynamics which are often encountered in nature. These characteristics include synchronization, injection locking, chaos, bifurcations, etc. To date, the applications of electronic oscillators has mostly been limited to communication systems.
