  1. 6. 2D-material nanocomposites with nonlinear optical properties for laser protection

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

    Author : Nils Ross; [2021]
    Keywords : optical power limiting; OPL; laser protection; nanocomposites; 2D-materials; graphene oxide; MXene; Ti3C2; melting gel; graphene; two-dimensional materials; nonlinear optical properties; NLO; spectroscopy;

    Abstract : Lasers are increasingly used for a wide range of different applications for both civil and military purposes. Due to the distinct properties of laser light, use of lasers often comes with a risk of damage to the human eye and other optical sensors. Therefore, an effective laser protection is needed.

  3. 7. Stretchable Barrier Coatings For Fiber-Based Materials : A laboratory study into the development of extensible/stretchable barrier coatings with nanoclay implementation, focusing on water vapour barrier properties.

    University essay from Karlstads universitet

    Author : Kajin Muradparist; [2021]
    Keywords : Stretchable; Barrier; Coating; WVTR; WVP; Hydroforming; Töjbar; Barriär; Bestrykning; WVTR; WVP; Hydroforming;

    Abstract : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. READ MORE

  4. 8. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

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

    Author : Cecilia Nemeth; [2020]
    Keywords : high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

    Abstract : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. READ MORE

  5. 9. Properties of Near-Infrared Type Ia Supernovae Light Curves

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Timothy Faerber; [2020]
    Keywords : Supernova; SNe Ia; Cosmology; Photometry; NIR;

    Abstract : As a result of the standardizability of SNe Ia light curves over a wide range of photometric bands, they are used as standard candles to accurately measure distances in the cosmos up to z ≈ 1 [22]. As dust extinction is smaller in the NIR than in the optical [21] there is less dispersion seen in the peak brightnesses of SNe Ia, making them truly standard candles. READ MORE

  6. 10. Transparent paper: Evaluation of chemical modification routes to achieve self-fibrillating fibres

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

    Author : Paulina Sandberg Birgersson; [2020]
    Keywords : Transparent paper; nanopaper; nanocellulose; chemical modification of cellulose; cellulose nanofibrils CNF ; Transparent papper; nanopaper; nanocellulosa; kemisk modifiering av cellulosa; cellulosa nanofibriller CNF ; nanopapper;

    Abstract : Transparenta papper tillverkade av cellulosa nanofibriller (CNF), visar stor potential att kunna ersätta petroleumbaserade plaster inom många användningsområden, till exempel för mat- och varuförpackningar. CNF, även känt som nanocellulosa, kombinerar viktiga cellulosaegenskaper, med unika egenskaper hos nanomaterial. READ MORE
