  1. 11. Carbon nanomaterials as electrical conductors in electrodes

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

    Author : Delan Shukr; [2021]
    Keywords : carbon; nanomaterials; graphene;

    Abstract : In this project, different molecules have been investigated with the purpose of creating anohmic contact between metals and carbon nano materials. In particular, we considered simplemolecules connecting a graphene layer and a copper-slab. READ MORE

  3. 12. Study of Monitoring Circuitry for Ageing in FPGAs

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

    Author : Pengxiang Cheng; [2021]
    Keywords : FPGAs; Ageing; Technology and Engineering;

    Abstract : Along with the down-scaling of CMOS technology, ageing has become one of the most important reliability challenges in CMOS devices. Ageing is defined as degradation in certain device characteristics such as delay, which can result in failure. READ MORE

  4. 13. Formulation of nanoemulsions stabilized by cellulose nanocrystals

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

    Author : Marco Maccagno; [2020]
    Keywords : nanocellulose; hydroxypropyl methilcellulose; Pickering emulsions; microfluidization; drug delivery; nanocellulosa; hydroxipropylmetylcellulosa; Pickering emulsioner; microfluidization; drogleverans;

    Abstract : Cellulose nanocrystals (CNCs) are bio-based nanoparticles with the ability to stabilize oil and water emulsions thanks to their intermediate wettability and nanometric size. These and other types of particle-stabilized emulsions, commonly referred to as Pickering emulsions, are of great academic and industrial interest due to their superior stability against drop coalescence compared to classical surfactant-stabilized emulsions.

  5. 14. Characterizing optical and electrical properties of monolayer MoS2 by backside absorbing layer microscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Nathan Ullberg; [2020]
    Keywords : backside absorbing layer microscopy; BALM; monolayer MoS2; TMD; TMDC; 2D materials; nanomaterials; nanotechnology; refractive index; extinction coefficient; absorption coefficient; field-effect transistor; FET; semiconductors; optoelectronics; optics; raw image processing; chemical vapor deposition; CVD; in situ characterization;

    Abstract : Nanomaterials are playing an increasing role in novel technologies, and it is important to develop optical methods to characterize them in situ.  To that end, backside absorbing layer microscopy (BALM) has emerged as a powerful tool, being capable to resolve sub-nanometer height profiles, with video-rate acquisition speeds and a suitable geometry to couple live experiments.
