  1. 1. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

    Författare :Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. LÄS MER

  3. 2. Magnesium and the Insulin Resistance Syndrome

    Författare :Arvo Hänni; L Resnick; Uppsala universitet; []
    Nyckelord :Medical sciences; magnesium; calcium; insuline resistance syndrome; hypertension; lipids; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Sammanfattning : Insulin resistance, defined as a state of reduced insulin-mediated glucose uptake in peripheral tissues, and disorders such as obesity, hypertension, and dyslipidemia, have been found to be associated in the conglomerate of the insulin resistance syndrome. Some antihypertensive drugs have been shown to decrease insulin sensitivity further. LÄS MER

  4. 3. Amorphous magnesium carbonate nanomaterials : Synthesis, characterization and applications

    Författare :Jiaojiao Yang; Ken Welch; Mika Lindén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high surface-to-volume ratio; nanoparticles; mesoporous; magnesium carbonate; amorphous drugs; supersaturated concentration; general adhesives; UV-shielding;

    Sammanfattning : High surface-to-volume ratio materials, including nanoparticles and mesoporous materials, have a number of applications due to their large surface area and special structures. Traditional approaches for synthesizing high surface-to-volume ratio nanomaterials are often complicated, expensive or environmentally unfriendly. LÄS MER

  5. 4. Biodegradable magnesium implants, immunomodulation, and tissue repair/regeneration

    Författare :Heithem Ben Amara; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipose tissue; Biodegradable implants; Bone–implant interface; Bone marrow; Inflammation; Cellular mechanotransduction; Gene expression; Immunohistochemistry; Magnesium; Neovascularization; Osseointegration; Soft tissue injuries;

    Sammanfattning : The century-old paradigm of holding fractures with a metallic implant to enable bone repair, known as osteosynthesis, is still used today without alteration. Patients are increasingly being treated with metallic implants made of magnesium (Mg) that secure osteosynthesis and are reabsorbed in situ without the surgical re-entry that requires their permanent analogs.

  7. 5. As-cast AZ91D magnesium alloy properties : Effects of microstructure and temperature

    Författare :Hoda Dini; Anders E.W. Jarfors; Nils-Eric Andersson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnesium; Magnesium Alloy; AZ91D; High-Pressure Die-Casting; Mechanical Property; Microstructural Characterisation; Physical Modelling; Dislocations; Distortion; Residual Stress; Magnesium; Magnesiumlegering; AZ91D; Pressgjutna; Mekanisk Egenskap; Mikrostrukturkarakterisering; Fysikalisk Modellering; Flytspänning; Dislokationer; Geometrisk Tolerans; Restspänning;

    Sammanfattning : Today, there is an essential need for lightweight, energy-efficient, environmentally benign engineering systems, and this is the driving force behind the development of a wide range of structural and functional materials for energy generation, energy storage, propulsion, and transportation. These challenges have motivated the use of magnesium alloys for lightweight structural systems. LÄS MER
