1. 1. Multilayer Structures for Biomaterial Applications : Biomacromolecule-based Coatings

   Författare :Tobias Halthur; Per M. Claesson; Bjørn Stokke; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilayer; layer-by-layer deposition; physical chemistry; surface chemistry; adsorption; ellipsometry; QCM-D; DPI; protein adsorption; polypeptides; biomaterials; biosurfaces; amelogenin; solid liquid interface; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : The cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied.

   Sammanfattning : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. LÄS MER

4. 3. Probing the Nano-Bio Interface Using Surface Based Analytical Techniques

   Författare :Rickard Frost; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanotoxicology; cell membrane; nanomedicine; melanophores; QCM-D; nanomaterial; DPI; AFM; supported lipid bilayer;

   Sammanfattning : In recent years, the use of manufactured nanomaterials has been rapidly increasing in a wide range of application areas. Among others, these areas of application include cosmetics, medicine, clothing, and sporting goods. The small size of nanomaterials offers unique properties that are not possible to obtain by the same material in bulk. LÄS MER

5. 4. Mechanisms of adhesive mixing for drug particle inhalation (Numerical investigation of the interplay between formulation variables)

   Författare :Mohammadreza Tamadondar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Element Method; Agglomerate; Carrier Particle; Adhesive mixing; Dispersion; DPI-formulation;

   Sammanfattning : Formulation of therapeutic dry powders for lung drug delivery via inhalation is done via adhesive mixing. In this process, micron-sized active pharmaceutical ingredient particles are blended with relatively coarse carrier particles until stable adhesive units of carrier and drug particles are formed.

7. 5. Biogas Production from Lignocellulosic Biomass : Impact of pre-treatment, co-digestion, harvest time and inoculation

   Författare :Chao LI; Bioteknik; []
   Nyckelord :Anaerobic digestion; Lignocellulosic biomass; Pretreatment; Co-digestion; Inoculation;

   Sammanfattning : Biogas or methane production through anaerobic digestion (AD) is gaining increasing attention worldwide due to concerns over global warming, energy security and the need for sustainable waste management. AD of lignocellulosic biomass is one facet that is highly appreciated since the conflict over biomass for food/feed or energy can be avoided. LÄS MER
