Different ancient mortar samples of Pamplona Cathedral have been analyzed to characterize their binder and aggregate fractions. A complete characterization has been carried out including chemical (complete macrochemical analysis, analysis of the soluble fraction in hot HCl (1:5) and of the insoluble residue, trace elements and soluble salts, using traditional chemical procedures, ion chromatogr...

the photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°c) and 500°c. the formed anatase nanoparticles were further modified as titania-silica...

Binder using ground granulated blast-furnace slag with specific surface area 20000cm2/g (GGBS20000) for ultra-high strength concrete were examined. As a result, it was possible to improve flowability of mortar by use proposal binder GGBS20000. And GGBS20000 also had the effect on improvement early-age mortar. However, which used silica fume more effective than produce high long-term strength.

Despite the numerous advantages of using concrete with high strength capacity, the brittle behavior of high strength concrete (HSC) and higher production cost has limited its use in the construction industry. This research aims to develop a cost-effective approach for production of high strength self-compacting concrete with desirable performance in either compressive or tensile loading conditi...

Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...

Title of Document: NEW ELECTROLYTE AND ELECTRODE MATERIALS FOR USE IN LITHIUMION BATTERIES Veidhes R. Basrur, Master of Science, 2010 Directed by: Prof. Srinivasa R. Raghavan & Prof. Chunsheng Wang Department of Chemical & Biomolecular Engineering Lithium-ion batteries have emerged as the preferred type of rechargeable batteries, but there is a need to improve the performance of the electrolyte...

We report a novel purification system for 6 His-tagged proteins by magnetic affinity separation. We have developed superparamagnetic Fe3O4@SiO core-shell particles with immobilized surface iminodiacetate groups to chelate with Ni. This Ni magnetic silica nanoparticle has been shown as an efficient carrier, binder and anchor to obtain his-tagged protein directly from total cell lysate. The struc...
