  1. 1. Convolutional neural networks for semantic segmentation of FIB-SEM volumetric image data

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Fredrik Skärberg; [2020-11-26]
    Keywords : Deep learning; convolutional neural networks; image analysis; semantic segmentation; focused ion beam scanning electron microscopy; porous materials; controlled drug release;

    Abstract : Focused ion beam scanning electron microscopy (FIB-SEM) is a well-established microscopy technique for 3D imaging of porous materials. We investigate three porous samples of ethyl cellulose microporous films made from ethyl cellulose and hydroxypropyl cellulose (EC/HPC) polymer blends. READ MORE

  3. 2. Fused deposition modeling of API-loaded mesoporous magnesium carbonate

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Andreas Abdelki; [2020]
    Keywords : Additive manufacturing; 3D-printing; Fused deposition modeling FDM ; Fused filament fabrication FFF ; Drug delivery; Amorphous drugs; Mesoporous magnesium carbonate; Upsalite; Cinnarizine; Hydroxypropyl cellulose HPC ; Hydroxypropyl methylcellulose acetate succinate HPMCAS ; Klucel ELF; AquaSolve LG;

    Abstract : In this thesis, the incorporation of drug loaded mesoporous magnesium carbonate as an excipient for the additive manufacturing of oral tablets by fused deposition modeling was investigated. Cinnarizine, a BCS class II drug, was loaded into the pores of the mesoporous material via a soaking method, corresponding to a drug loading of 8.68 wt%. READ MORE

  4. 3. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Segervald; [2019]
    Keywords : AFM; NIL; SPR; SERS; nanohole; nanohole array; nanoimprint lithography; physical vapor deposition; plasma treatment; plasmonic; plasmons; surface plasmon resonance; localized surface plasmon resonance; metal enhanced fluoresence; surface enhanced raman spectroscopy; transmittance; nanoplasmonic; signal enhancement;

    Abstract : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. READ MORE

  5. 4. Effect of manufacturing conditions and polymer ratio on the permeability and film morphology of ethyl cellulose and hydroxypropyl cellulose free-films produced by using a novel spray method.

    University essay from Institutionen för farmaci

    Author : Annica Jarke; [2009]
    Keywords : free-film; confocal laser scanning microscopy; water permeability;

    Abstract : This thesis considers the effect of manufacturing conditions and polymer ratio on water permeability and morphology of free-films. A novel spray method for producing ethyl cellulose (EC) and hydroxypropyl cellulose (HPC) free-films was developed where several process parameters was controlled. READ MORE
