  1. 16. Thermomechanical characterisation of newly developed UHMWPE composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Petra Jan; [2019]
    Keywords : UHMWPE; nanocomposites; thermomechanical characterisation;

    Abstract : Ultra high molecular weight polyethylene (UHMWPE) is a polymer commonly used in various applications, particularly in hip joint replacements. Despite its good performance, it is susceptible to oxidation degradation, which can be mitigated with the addition of vitamin E, and to excessive wear against metal countersurfaces, which can potentially be improved with the addition of nanoparticles.

  3. 17. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced composites

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jiacheng Lin; Haoran Teng; [2019]
    Keywords : Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification.; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

    Abstract : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. READ MORE

  4. 18. Nano-Graphene Oxide Surface-Functionalized Poly(e-caprolactone) Scaffolds with Drug Delivery Capability

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Yao Jenevieve Linell; [2018]
    Keywords : Poly e-caprolactone PCL ; aminolysis; graphene oxide; tissue scaffolds; ciprofloxacin;

    Abstract : Grafenoxid (GO) ar en lovande kandidat som nano-tillsats i medicinska byggnadsstallningar for benregenerering. GO kan forbattra den biologiska kompatibiliteten och osteogena prestandan hos polymerbaserade byggstallningar, och ocksa vasentligt bidra till forbattringen av materialets mekaniska egenskaper.

  6. 20. Modelling Graphene Field-Effect Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sofia Sjölander; [2017]
    Keywords : Graphene; FET; GFET; Field Effect-transistor; QMUL; Technology and Engineering;

    Abstract : Today, transistors with 20 nanometer (nm) channel length are in mass production and many researchers believe that we are reaching a limit with downsizing conventionally used silicon metal-oxide-semiconductor field-effect transistors (MOSFETs) [1]. To keep up with the trend of making the transistor smaller, new channel materials are studied, and graphene has come into the spotlight. READ MORE
