  1. 1. 3D Printing Hydrogel Artificial Muscles and Microrobotics

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Malin Alterby; Emily Johnson; Anton Jonason; Denize Svensson; [2023]
    Nyckelord :3D printing; MXene; CNT; CNF; hydrogel; actuator;

    Sammanfattning : The purpose of this lab was to investigate the printability of cellulose nanofiber/carbon nanotubes, their functions as actuators, and to compare these properties with MXene/nano cellulose gels. Data on MXene/nano cellulose gel was obtained from previous research made by Hamedi labs. LÄS MER

  3. 2. Investigation of the interaction of A-MYB and TCFL5 on pachytene PIWI-interacting RNA genes in two sub-species of mice, mus musculus musculus and mus musculus castaneus

    Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Most Shova Banu; [2023]
    Nyckelord :;

    Sammanfattning : Spermatogenesis is a complex process that involves the production of sperm cells from germ cells in order to transmit genetic information to progeny. The PIWI-interacting RNA (piRNA) is a non-coding small silencing RNA that guides the PIWI protein to silence target transposon transcripts to regulate the production of germ cells. LÄS MER

  4. 3. Investigating Yttrium Ruthenate Pyrochlore as an Anodic Electrocatalyst in Proton Exchange Membrane Water Electrolysis

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Kneev Sharma; [2023]
    Nyckelord :;

    Sammanfattning : As the energy transition progresses, the demand for green storage solutions is ever-increasing. Hydrogen storage is receiving increased interest and support due to its promising sustainability and flexibility. Proton-exchange, or polymer electrolyte, membrane (PEM) electrolyzers are a key technology supporting hydrogen storage systems. LÄS MER

  5. 4. Optimising microfluidic preparation of lipid sponge phase nanoparticles for biomolecule encapsulation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Owais Khalil; [2023]
    Nyckelord :Sponge phase; lipid nanoparticles; microfluidics; SAXS; cryo-TEM; DLS; chemical engineering; Chemistry;

    Sammanfattning : Drug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. LÄS MER

  7. 5. In Situ and Ex Situ Study of Nanoparticles Stability and Transformation in Simulated Aquatic Natural Media

    Kandidat-uppsats, KTH/Kemi

    Författare :Dinh Nguyen; Jonathan Samuelsson; Vilma Grönvall; [2022]
    Nyckelord :nanoparticles; freshwater; natural organic matter NOM ; agglomeration; dissolution; genotoxicity; atomic absorption spectroscopy AAS ; nanoparticle tracking analysis NTA ; inductively coupled plasma ICP ; nanopartiklar; färskvatten; naturligt organiskt material NOM ; agglomerering; upplösning; genotoxicitet; atomabsorptionsspektroskopi AAS ; nanopartikelspårning analys NTA ; induktivt kopplad plasmaanalys ICP ;

    Sammanfattning : Nanopartiklar är partiklar med storlekar i området 1 till 100 nm, och som uppvisar nanospecifika egenskaper. Egenskaperna kan variera helt mellan olika typer av nanopartiklar, även bland partiklarna och deras respektive material i bulk format på grund av deras unika storlekar, former och strukturer. LÄS MER
