1. 1. Biodegradable Surfactants Containing Hydrolyzable Bonds

   Författare :Maria Stjerndahl; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amide; alkaline hydrolysis; cleavable surfactant; carbonate; ester; biodegradation; CMC; enzymatic hydrolysis; mixed micelle;

   Sammanfattning : Surfactants with built-in weak bonds, so-called cleavable surfactants, are interesting candidates in the search for more environmentally friendly alternatives to traditional surfactants. The objective of this thesis was to perform a systematic study in which cleavable surfactants with different hydrolyzable bonds were compared with regard to physicochemical properties, and chemical and biological stability.

3. 2. Structure and energetics of molecular recognition in galectin-3-ligand interactions

   Författare :Rohit Kumar; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein-ligand interactions; molecular recognition; weak bonds; thermodynamics; enthalpy; entropy; galectin-3; carbohydrate recognition domain; x-ray crystallography; fluorescence polarization; isothermal titration calorimetry; neutron crystallography; ;

   Sammanfattning : Molecular recognition is the key aspect of any cellular and biological function. Two or more molecules interacting with each other cause the effects that drives various basic functions that are fundamental to cells. Be these protein-protein, protein-nucleic acid or protein-ligand interactions, they all play important roles in a cell. LÄS MER

4. 3. Essays on the term structure of interest rates and long-run risks

   Författare :Henrik Hasseltoft; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Stocks, Bonds, and Long-Run Consumption Risks. Bansal and Yaron (2004) show that long-run consumption risks and time-varying economic uncertainty in conjunction with recursive preferences can account for important features of equity markets. LÄS MER

5. 4. Is building molecular solid-state structures as easy as playing with Lego?

   Författare :Cédric Borel; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MOF; framework; crystal structures; network; coordination chemistry;

   Sammanfattning : Crystal engineering is a science dealing with molecular solid-state compounds. One major development in the last ten years has been the description of structures as if they were forming network. In this simplified approach to the structures where atoms, molecules, and molecular ions are replaced by a construction of edges and nodes forming a net. LÄS MER

7. 5. Phthalates : On the issue of sources, human uptake, time trends and health effects

   Författare :Huan Shu; Carl-Gustaf Bornehag; Eewa Nånberg; Åke Svensson; Tina Kold Jensen; Karlstads universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phthalates; Asthma; Pregnant; Exposure; Endocrine disrupting chemicals; SELMA; Public Health Science; Folkhälsovetenskap;

   Sammanfattning : Human health depends on a well-functioning endocrine system to regulate hormone release for normal bodily functions. Endocrine disrupting chemicals (EDCs) constitutes a group of chemicals, included in many commonly used products, (e.g. LÄS MER
