  1. 1. Determining the interwall spacing in carbon nanotubes by using transmission electron microscopy

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Tobias Tyborowski; [2016]
    Keywords : MWCNT Multiwall Carbon Nanotubes Interwall Interlayer Spacing TEM Transmission Electron Microscopy Defocus;

    Abstract : The interwall spacing of multi-walled carbon nanotubes has an effect on their physical and chemical properties. Tubes with larger interwall spacing - compared to the spacing where the carbon atoms are in their natural distance to each other - are for instance expected to be mechanically less stable. READ MORE

  2. 2. Fabrication of surface enhanced Raman spectroscopy (SERS) active substrates based on vertically aligned nitrogen doped carbon nanotube forest

    University essay from Umeå universitet/Institutionen för fysik

    Author : Md Khorshed Alam; [2015]
    Keywords : Photolithography; Physical Vapor Deposition; Chemical Vapor Deposition; Annealing; Scanning Electron Microscopy; Surface Enhanced Raman Spectroscopy;

    Abstract : This thesis work describes the fabrication and surface enhanced Raman spectroscopy (SERS) characterization of vertically aligned nitrogen (N) doped multi walled carbon nanotube (MWCNT) forests coated by silver (Ag) and gold (Au) nanoparticles. In the present work, the CNT forests were grown from a catalyst metal layer by the chemical vapor deposition (CVD) process at temperature of 800 oC and a physical vapor deposition (PVD) and annealing processes were applied subsequently for the evaporation and diffusion of noble metal nanoparticles on the forest.

  3. 3. NANOMATERIALS FOR THE DECONTAMINATION OF WASTE WATER CONTAINING PHARMACEUTICAL DRUGS

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Joydip Paul; [2015]
    Keywords : ;

    Abstract : The existent of pharmaceutical drugs in our aquatic media is a preeminent burden for the environment effect including health fitness issues. The presence of tiny amount of organic and inorganic pharmaceutical drugs including hormones, birth control pills, NSAID, antibodies can causes a huge destruction for our living entity now a days.

  4. 4. Mobilization and transport of different types of carbon-based engineered and natural  nanoparticles through saturated porous media

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maryeh Hedayati; [2014]
    Keywords : Nanoparticle; MWCNT; C60; Transport and mobilization; DLVO theory; Ionic strength; Input concentration; Clean-bed filtration theory; Column test;

    Abstract : Carbon –based engineered nanoparticles have been widely used due to their small size and uniquephysical and chemical properties. They can dissolve in water, transport through soil and reach drinkingwater resources. READ MORE
