2. 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

4. 2. Crystal structures of human deoxyribonucleotidases

   Author : Agnes Rinaldo-Matthis; Pär Nordlund; David K Stammers; Stockholms universitet; []
   Keywords : crystal structure;

   Abstract : Human 5’-deoxyribonucleotidases are ubiquitous enzymes that catalyze the dephosphorylation of deoxyribonucleoside monophosphates to their nucleoside form. They participate in the regulation of deoxyribonucleotide pools and protect DNA replication from inbalance of precursors. READ MORE

5. 3. On the Formation of Supported Phospholipid Bilayers

   Author : Erik Reimhult; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; vesicle adsorption; formation kinetics; SPR; QCM-D; SPB; AFM; supported lipid bilayer; supported membrane; liposome;

   Abstract : Lipid bilayers are a central component of both the structure and function of biological membranes, like the one surrounding cells of living organisms. Since the lipid bilayer provides a host matrix for membrane proteins, which perform many of the specialized tasks in cells like energy, signal and material transduction, researchers have tried to develop artificial model membranes to study a variety of membrane protein functions.

6. 4. Numerical Modeling of Plasticity in FCC Crystalline Materials Using Discrete Dislocation Dynamics

   Author : Arash Hosseinzadeh Delandar; Pavel Korzhavyi; Rolf Sandström; Mikko Alava; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dislocations; crystal plasticity; discrete dislocation dynamics; Cu single crystal; high strain rate deformation; strain rate sensitivity; plastic anisotropy; slip band formation; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : Plasticity in crystalline solids is controlled by the microscopic line defects known as “dislocations”. Decisive role of dislocations in crystal plasticity in addition to fundamentals of plastic deformation are presented in the current thesis work. READ MORE

7. 5. Biomimetic Formation of Calcium Phosphate Based Nanomaterials

   Author : Wenxiao He; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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.
