  1. 1. A Multi-Scale Approach To Adhesive Mixing

    Författare :Duy Nguyen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive particle mixing; CFD simulation; multiscale; dry particle coating; regime map.; DEM simulation; dry powders for inhalation;

    Sammanfattning : Adhesive particle mixing is a fundamental process in many applications, especially in dry powders for inhalation. Despite its importance, a mechanistic process description for designing the structure of interest is still lacking. LÄS MER

  3. 2. 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.

  4. 3. Understanding Adhesive Mixtures for Inhalation : Particle Dynamics Modelling and Segregation Experiments

    Författare :Sohan Sarangi; Göran Frenning; Göran Alderborn; Kyrre Thalberg; Johannes Khinast; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inhalation; adhesive mixtures; dry powder inhaler; discrete element method; segregation; stability; modeling; Galenisk farmaci; Pharmaceutics; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Pulmonary route has been used as a source of drug delivery to lungs for centuries. Drugformulation decides the type of inhaler devices such as pressurized metered-dose inhalers(pMDIs), nebulizers and dry powder inhalers (DPIs). LÄS MER

  5. 4. Novel Microfluidic Devices Based on a Thermally Responsive PDMS Composite

    Författare :Björn Samel; Göran Stemme; Jörg Kutter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEMS; microsystem technology; micro total analysis system; lab-on-a-chip; microfluidics; composite actuator; expandable microspheres; PDMS; poly dimethylsiloxane; disposable; wafer bonding; adhesive bonding; PDMS bonding; adhesive PDMS bonding; selective PDMS bonding; microcontact printing; Electrical engineering; Elektroteknik;

    Sammanfattning : The field of micro total analysis systems (μTAS) aims at developments toward miniaturized and fully integrated lab-on-a-chip systems for applications, such as drug screening, drug delivery, cellular assays, protein analysis, genomic analysis and handheld point-of-care diagnostics. Such systems offer to dramatically reduce liquid sample and reagent quantities, increase sensitivity as well as speed of analysis and facilitate portable systems via the integration of components such as pumps, valves, mixers, separation units, reactors and detectors.
