  4. 2. Anions and Additives for Lithium Battery Electrolytes

    Author : Johan Scheers; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lithium batteries; additives; Raman spectroscopy; anions; ab initio; electrolytes; ion pairs;

    Abstract : Based on the atomic postulate, which is now more than 2400 years old, scientists have developed very advanced tools for studying the material world. With the potential realized with modern computers, more and more sophisticated methods are available for predicting real material properties, even from simple theoretical model systems. READ MORE

  5. 3. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

    Author : Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

    Abstract : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. READ MORE

  6. 4. Amphiphilic Polymers as Additives in Biomedical Polyurethanes. Surface Properties and Morphology

    Author : Maria Kober; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer micelles; phase separation; migration; poly ethylene oxide ; surface enrichment; morphology; polyurethane; additives; Surface modification; amphiphilic polymers; polymer blends; Polymer technology; biopolymers; Polymerteknik;

    Abstract : The aim of this work was to achieve surface modification of two biomedical polyurethanes and one poly(urethane urea) through the addition of small amounts of amphiphilic copolymers in solution. The matrix polymers used were the poly(ether urethane)s Pellethane 2363-80AE (P80) and 2363-75D (P75) and a poly(ether urethane urea) similar to Biomer (PUUR). READ MORE

  7. 5. Improving alternatives assessment of plastic additives : exploring in silico tools to identify less hazardous flame retardants

    Author : Ziye Zheng; Patrik L. Andersson; Hans Peter Arp; Gregory Peters; Gerrit Schüürmann; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical alternatives assessment; plastic additives; flame retardants; hazard; emission; in silico; modeling; quantitative structure-activity relationship QSAR ; multi-criteria decision analysis MCDA ; environmental science; miljövetenskap; organisk kemi; Organic Chemistry; ekotoxikologi; Ecotoxicology; Toxicology; toxikologi;

    Abstract : Alternatives assessment is applied for replacing hazardous chemicals with viable, safer substitutes. High quality experimental hazard data, however, are usually unavailable for this purpose, and obtaining in silico data is the only approach to fill in data gaps. READ MORE
