  1. 1. Pharmaceutical cocrystals : formation mechanisms, solubility behaviour and solid-state properties

    Author : Amjad Alhalaweh; Peter York; Luleå tekniska universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crystal engineering; cocrystal; formation; solubility; pH; dissolution; surface properties; solid-state properties; Health Science; Hälsovetenskap;

    Abstract : The primary aim of pharmaceutical materials engineering is the successful formulation and process development of pharmaceutical products. The diversity of solid forms available offers attractive opportunities for tailoring material properties. READ MORE

  2. 2. Improving cellulose fibre properties by controlled adsorption of xylans

    Author : Tobias Köhnke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Isolation; Lignin-carbohydrate complexes; Adsorption; Extraction; Tensile strength; Aggregation; Softwood kraft pulp; Cellulose fibre; Hornification; Xylan;

    Abstract : Hemicelluloses are, together with cellulose and pectins, the polysaccharide constituents in the cell walls of higher plants. Xylans are the most common hemicelluloses, and are considered to be the second most abundant biopolymer in the plant kingdom. READ MORE

  3. 3. Factors Related to the Formation of Gas Porosity in Grey Cast Iron: Investigation of Core Gas Evolution and Gas Concentrations in Molten Iron

    Author : Jessica Orlenius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; core binders; Gas porosity; hydrogen; grey iron; gas absorption; nitrogen; oxygen; gas evolution rate; green sand; mould filling; gas volume; gas solubility;

    Abstract : Since gas porosity is a major casting problem, it is of greatest importance to increase the knowledge about the foundry process in order to minimise the presence of gas porosity and thereby improving the casting quality. Gas porosity is generally considered to originate from gases precipitated during solidification of iron and from entrained gas picked up by the metal during the mould filling. READ MORE

  4. 4. Fabrication and Testing of Doped Uranium Nitride as an Accident Tolerant Fuel Alternative

    Author : Luis Guillermo Gonzalez Fonseca; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; internal gelation; density; Uranium nitride; sintering; microspheres; doping; waterproofing.; ATF;

    Abstract : Nuclear energy is a carbon-free energy source often considered less harmful to the environment than fossil fuels. However, accidents have shown that there are some safety concerns regarding nuclear energy that need to be continuously assessed and further improved. READ MORE

  5. 5. Diffusion Controlled Drug Release from Slurry Formed, Porous, Organic and Clay-derived Pellets

    Author : Erik Jämstorp Berg; Maria Strømme; Håkan Engqvist; Susanne Bredenberg; Pentti Tengvall; Nanoteknologi och funktionella material Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion; Drug delivery; Antithrombotic drugs; Highly potent opioids; Modeling; Clays; Polymers; Pellets; Beads; Materialvetenskap; Materials Science;

    Abstract : Coronary artery disease and chronic pain are serious health issues that cause severe discomfort and suffering in society today. Antithrombotic agents and highly potent analgesics play a critical role in improving the recovery process for patients being treated for these diseases. READ MORE
