  1. 1. Biomimetic Formation of Calcium Phosphate Based Nanomaterials

    Författare :Wenxiao He; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; superstructure; lyotropic liquid crystal; self-assembly; Calcium phosphate; bone-like apatite; amphiphilic peptide; nanocomposite; biomimetic mineralization;

    Sammanfattning : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

  3. 2. Terpenoid Conidiation Factors in Penicillium cyclopium

    Författare :Yanhong He; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetals; hydrolysis; Biotechnology; Bioteknik; total synthesis; analogues; synthesis; conidiogenone; conidiogenol; terpenoid; Penicillium cyclopium; conidiation inducing activity; Natural product; fungal metabolites;

    Sammanfattning : Filamentous fungi produce asexual dispersive spores (conidia), when conditions are not suitable for apical extension growth. Conidiation (the process by which conidia produced) in genus Penicillium has attracted considerable interest because of its wide usage in different areas. LÄS MER

  4. 3. Iodine Isotopes and their Species in Surface Water from the North Sea to the Northeastern Atlantic Ocean

    Författare :Peng He; Ala Aldahan; Per Roos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iodine isotopes; 129I; 127I; oceans; North Sea; speciation; Atlantic Ocean; English Channel; Celtic Sea; AMS; iodine chemistry; geochemistry; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Huge amounts of anthropogenic 129I have been and still are released to the environment through liquid and gaseous discharges from the nuclear fuel reprocessing facilities worldwide and in particular the ones in Europe. Most of this 129I signal has been accumulated in the marine environment which plays a major role in the iodine natural pool. LÄS MER

  5. 4. A novel prophylactic strategy to minimize stem cell transplantation-related complications

    Författare :Rui He; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hematopoietic stem cell transplantation (HSCT) is a curative treatment and sometimes is the only option for patients with hematological malignancies and some types of solid tumors. It is also the first-line treatment for several severe genetic and metabolic disorders. LÄS MER

  7. 5. High-Capacity Cool Thermal Energy Storage for Peak Shaving - a Solution for Energy Challenges in the 21st century

    Författare :Bo He; KTH; []
    Nyckelord :Comfort cooling; peak shaving; phase change materials PCM ; cool thermal energy storage; DSC; phase change temperature; the heat of fusion; phase equilibrium; phase diagram.;

    Sammanfattning : Due to climatic change, increasing thermal loads inbuildings and rising living standards, comfort cooling inbuildings is becoming increasingly important and the demand forcomfort cooling is expanding very quickly around the world. Theincreased cooling demand results in a peak in electrical powerdemand during the hottest summer hours. LÄS MER
