  1. 1. Nanoconfined imidazolium ionic liquids

    Författare :Szilvia Vavra; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface active ionic liquids; protic ionic liquids; nanoconfinement; oriented and parallel nanochannels;

    Sammanfattning : Long-chain ionic liquids are attracting interest as alternatives to their short-chain analogues as electrolytes. At the same time, they are also considered as alternatives to mesogens and conventional surfactants as templates. LÄS MER

  3. 2. Different paths to explore confined crystallisation of PCL

    Författare :Nima Sanandaji; Ulf W. Gedde; Mikael S Hedenqvist; Javier Martinez de Salazar; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; crystallisation; poly-ε-caprolactone; end groups; morphology; nanoconfinement; melting; monodisperse; RESS; injet printing;

    Sammanfattning : In this work, different paths to confined crystallisation of poly(ε-caprolactone) (PCL) havebeen explored. Innate confinement effects due to the presence of bulky end groups wereshown to affect crystalline characteristics for strictly monodisperse ε-caprolactone oligomers. LÄS MER

    Författare :Irina Zubritskaya; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photonics; magnetoplasmonics; magneto-optics; magneto-optical Kerr effect MOKE ; plasmon ruler; nickel; cobalt; gold; silicon; localized surface plasmon resonance; dimer; trimer; chiroptics; chiral transmission; 2D nanoantennas; dynamic tuning; metal-dielectric; 3D nanoantennas; metasurface; magnetic modulation; perpendicular magnetic anisotropy.;

    Sammanfattning : Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple electromagnetic (EM) radiation on a sub-wavelength length scale to free electrons, forming propagating or localized surface plasmons, provide many exciting functionalities due to their ability to manipulate light via the local EM field shaping and enhancement.
