To achieve carbon targets,the European Union(EU)aims to promote nearly zero-energy buildings(nZEB).To enable the necessary transition,technical solutions need to converge with socio-economic factors,such values and awareness of stakeholders involved in the decision-making *** this light,the aim of this paper is to characterise perceived drivers and barriers to nine energy-efficient technologies(EET),according to key decision-makers’and persuaders of the technology selection in the EU residential building *** are collected across eight EU countries,***(BE),Germany(DE),Spain(ES),France(FR),Italy(IT),Netherlands(NL),Poland(PL),and United Kingdom(UK).The stakeholders’selected are architects,construction companies,engineers,installers and demand-side *** from a multi-country survey is analysed to calculate the share of 15 drivers and 21 barriers(aggregated to 5 groups),being selected for each EET and *** 5 groups considered to analyse drivers and barriers are environmental,technical,economic,social,*** perceived barriers and drivers were further studied for their association across the countries using the Pearson’s Chi2 and a Cramer’s V *** results demonstrate that across all EETs and countries,the technical and economic driver groups are perceived to have the highest potential to increase the implementation rate of *** terms of barriers,economic aspects are seen as the foremost reason that EET are not scaling *** both drivers and barriers legal aspects are the least often *** overall the barrier groups show significant variation across countries compared to driver *** findings provide an evidence-basis to better understand arguments in favour and against specific EETs and,in this way,support policy makers and other interested parties to increase the market share of the selected solutions.

Tetraamido-oxacalix[4]arene Derivatives： Synthesis, Structures and Supramolecular Assemblies

Chinese Journal of chemistry 2013年第5期31卷 684-688页

作者： Lingwei Kong Mingliang Ma Xiaoli Zhao Yahua Liu Xianqiang Mi Biao Jiang Ke Wen ~hanghai Engineering Research Center of Molecular Therapeutics and New Drug Development East China Nor- mal University Shanghai 200062 China Shanghai Key Laboratory of green chemistry and Chemical Processes and Department of Chemistry East China Normal University Shanghai 200062 China Medicinal chemistry ChemBridge Research Laboratories Inc. San Diego CA 92127 USA sustainable technology Research Center Shanghai Advanced Research Institute Chinese Academy of Sciences Shanghai 201203 China

Tetraamido-oxacalix[4]arene derivatives have been synthesized via the reactions of tetraamino-oxacalix[4]arene with excess butyryl chloride, octanoyl chloride, benzoyl chloride and p-toluenesulfonyl chloride, respectively. JH NMR results suggest that these oxacalix[4]arene derivatives preferentially adopt the 1,3-alternate （saddle-like） con- formation in solution, which were also the case in the solid state as demonstrated by single crystal X-ray analysis. A dimerized slipped capsule could be formed by tetra-butyramido-oxacalix[4]arene in the solid state via intermolecu- lar hydrogen bond interactions under the assistance of two encapsulated methanol molecules. On the other hand, a molecular cavity was formed by tetra-p-toluenesulfonamido-oxacalix[4]arene which can encapsulate a solvent molecule of ethyl acetate.
