Gold-Nanoparticle-Immobilized Desalting Columns for Highly Efficient and Specific Removal of Radioactive Iodine in Aqueous Media
ACS Applied Materials & Interfaces, 2016Co-Authors: Mi Hee Choi, Ha Eun Shim, Dae Seong Choi, Yong Jun Choi, Seong-jae Yun, Sang-hyun Park, Beom-su Jang, Jongho JeonAbstract:There has been worldwide attention on the efficient removal of radioactive iodine, because it is commonly released in nuclear plant accidents. Increasing concerns on environmental problems due to the radioactive iodine are leading us to develop stable and Sustainable Technology for remediation of radioelement contaminants. In this work, we report a highly efficient chromatographic method for specific and rapid capture of radioactive iodine. The gold nanoparticles immobilized dextran gel columns showed excellent removal capabilities of radioactive iodine in various conditions. These results suggested that our platform Technology can be a promising method for the desalination of radioactive iodines in water.

innovation system strengths and weaknesses in progressing Sustainable Technology the case of swedish biorefinery development
Journal of Cleaner Production, 2016Co-Authors: Hans Hellsmark, Johanna Mossberg, Patrik Soderholm, Johan FrishammarAbstract:Based on the combination of economic challenges and uncertain policy conditions in the United States, European Union, and elsewhere, the development of advanced biorefineries has progressed slower than anticipated. This has delayed the transition to a more Sustainable and less carbon-intensive economy. In this article, we adopt the technological innovation system (TIS) approach to analyze advanced biorefinery development in Sweden, a front-runner country in current development. The analysis highlights a number of system strengths (e.g., long-term research funding; significant research infrastructure; strong actor networks) that have contributed to developing the Swedish TIS, but also important system weaknesses (e.g., weak coordination among ministries; lack of industrial absorptive capacity; unclear roles) inhibiting it. The article highlights a combination of four policy measures that build on the system strengths to address the system weaknesses: (a) the implementation of a deployment policy for creating domestic niche markets; (b) improved policy timing and more structured coordination among different governmental agencies; (c) the provision of stronger incentives for mature industries to invest in RD and (d) improved organization and financing of existing research infrastructure. In addition to the empirical contribution, the article contributes with novel insights into the TIS framework by highlighting the dynamics between system strengths and weaknesses, and suggests that system strengths should be better emphasized in future TIS studies.

lipophilization of hydroxytyrosol enriched fractions from olea europaea l byproducts and evaluation of the in vitro effects on a model of colorectal cancer cells
Journal of Agricultural and Food Chemistry, 2017Co-Authors: Roberta Bernini, Isabella Carastro, Gaia Palmini, Annalisa Tanini, Roberto Zonefrati, Patrizia Pinelli, Maria Luisa Brandi, Annalisa RomaniAbstract:A hydroxytyrosol (HTyr)-enriched fraction containing HTyr 6% w/w, derived from Olea europaea L. byproducts and obtained using an environmentally and economically Sustainable Technology, was lipophilized under green chemistry conditions. The effects of three fractions containing hydroxytyrosyl butanoate, octanoate, and oleate, named, respectively, lipophilic fractions 5, 6, and 7, and unreacted HTyr on the human colon cancer cell line HCT8-β8 engineered to overexpress estrogen receptor β (ERβ) were evaluated and compared to those of pure HTyr. The experimental data demonstrated that HTyr and all fractions showed an antiproliferative effect, as had been observed by the evaluation of the cellular doubling time under these different conditions (mean control, 32 ± 4 h; HTyr 1, 65 ± 9 h; fraction 5, 64 ± 11 h; fraction 6, 62 ± 14 h; fraction 7, 133 ± 30 h). As evidenced, fraction 7 containing hydroxytyrosyl oleate showed the highest activity. These results were related to the link with ER-β, which was assessed through simultaneous treatment with an inhibitor of ERβ.
