• On Bezier surfaces in three-dimensional Minkowski space

  Ugail, Hassan; Marquez, M.C.; Yilmaz, A. (2011)

  In this paper, we study Bézier surfaces in View the MathML source three-dimensional Minkowski space. In particular, we focus on timelike and spacelike cases for Bézier surfaces. We also deal with the Plateau¿Bézier problem in View the MathML source, obtaining conditions over the control net to be extremal of the Dirichlet function for both timelike and spacelike Bézier surfaces. Moreover, we provide interesting examples showing the behavior of the Plateau¿Bézier problem in View the MathML source and illustrating the relationship between it and the corresponding Plateau¿Bézier problem in the Euclidean space R3.
• Biomaterial Functionalized Surfaces for Reducing Bacterial Adhesion and Infection

  Katsikogianni, Maria; Wood, David J.; Missirlis, Y.F. (2016)

  This chapter describes the current approaches to reduce bacterial adhesion to various biomaterial surfaces, focusing on nonfouling surfaces through patterning and hydrophobicity plasma-assisted surface treatment and deposition; incorporation of antimicrobials, antibiotics, antibiofilms, and natural extracts that are either immobilized or released; dual function antimicrobial surfaces; incorporation of nonpathogenic bacteria, bacteriophages, and biofilm dispersal agents but also reduced bacterial adhesion through tissue integration. To facilitate the design of new materials, the role of physical, chemical, and biological surface properties on bacterial adhesion is reviewed in each case, as an insight into the chemical and physical cues that affect bacterial adhesion and biofilm formation can provide ideas for creating successful antifouling or antimicrobial surfaces. The application of these surfaces is explored based on the clinical needs and the market gaps. How multidisciplinary research on surface design and engineering may have an impact on both fundamental understanding of bacterial adhesion to biomaterials and applied biomaterial science and technology is finally discussed.
• Polymer Technologies for the Control of Bacterial Adhesion - From Fundamental to Applied Science and Technology

  Katsikogianni, Maria; Missirlis, Y.F. (2014)

  This article describes how an insight into the chemical and physical cues that affect bacterial adhesion and biofilm formation can provide ideas for creating successful antifouling or antimicrobial surfaces. To facilitate the design of new materials, the role of physical and chemical properties on bacterial adhesion is reviewed. The current approaches to reduce bacterial adhesion to various polymeric surfaces are discussed, as well as how multidisciplinary research on surface design and engineering may have an impact on both fundamental and applied microbiological science and technology.
