    This report draws on the results of a self-assessment survey conducted on national adaptation policy processes in Europe. In May 2013, the survey was sent out by the European Environment Agency (EEA) to authorities in countries responsible for coordinating adaptation at national level (the EEA 32 member countries, and in Croatia in July 2013 as a new EU Member State and EEA member country). Some 30 EEA member countries provided their responses on a voluntary basis. Thanks to the high response rate and the wealth of information provided by these European countries, this report presents a unique collection of information and the largest and most comprehensive overview of national adaptation policy processes in Europe, to date.

    In this paper, the performances of two iron-based syngas-fueled chemical looping (SCL) systems for hydrogen (H2) and electricity production, with carbon dioxide (CO2) capture, using different reactor configurations were evaluated and compared. The first investigated system was based on a moving bed reactor configuration (SCL-MB) while the second used a fluidized bed reactor configuration (SCL-FB). Two modes of operation of the SCL systems were considered, namely, the H2 production mode, when H2 was the desired product from the system, and the combustion mode, when only electricity was produced. The SCL systems were modeled and simulated using Aspen Plus software. The results showed that the SCL system based on a moving bed reactor configuration is more efficient than the looping system with a fluidized bed reactor configuration. The H2 production efficiency of the SCL-MB system was 11 % points higher than that achieved in the SCL-FB system (55.1 % compared to 44.0 %). When configured to produce only electricity, the net electrical efficiency of the SCL-MB system was 1.4 % points higher than that of the SCL-FB system (39.9 % compared to 38.5 %). Further, the results showed that the two chemical looping systems could achieve >99 % carbon capture efficiency and emit ~2 kg CO2/MWh, which is significantly lower than the emission rate of conventional coal gasification-based plants for H2 and/or electricity generation with CO2 capture.

    Abstract In this article, we investigate the intergenerational transmission of sustainable consumption practices. Whereas previous studies have used self-reported attitudes and behaviour, this study uses data on actual energy consumption for space-heating and hot water combined with extensive panel data from Danish administrative registers. The paper shows significant intergenerational correlations between the energy consumption patterns of adults and their mothers, also when controlling for the energy consumption of the mother-in-law, where possible. Furthermore, it shows that the intergenerational correlation is slightly stronger for adults with lower income levels. These results suggest that energy consumption practices are shared and reproduced within the family. Following theories of practice, the intergenerational similarities in energy consumption practices refer to bodily learned practices that are indirectly transmitted and negotiated through family relations. In this way, these findings also contribute to a better understanding of how practical understanding regarding how to perform practices is transmitted within more ordinary aspects of consumption that play a less obvious role in distinction. To ensure more sustainable consumption practices in the future, this paper points to the importance of the role of family relations and the transmission of embodied practices.

    Nowadays, many construction companies use maturity-based approaches to support decisions that have strong impact on costs and sustainability of the construction process, such as: age of pre-stressing operations, decision of propping/formwork removal; instant of subjection to load, etc. Current approaches to quality control through maturity consist in evaluating the compressive strength evolution of the concrete mix at a reference curing temperature (usually 20°C), together with the determination of the apparent activation energy (Ea) of the mix. The value of Ea is usually obtained from one of these three sources: (i) reference recommendations based on the type of cement; (ii) calorimetric testing; (iii) testing of compressive strength evolution at several distinct temperatures. The only technique of determining Ea that really addresses a mechanical property is the latter one, demanding however the deployment of many specimens and tests. Furthermore, the destructive character of this technique limits the possibility of maintaining the same specimen for the entire Ea testing, thus increasing the variability/scattering of results. The present study intended to evaluate the possibility of assessing mechanical-based activation energy for concrete through continuous or quasicontinuous assessments of E-modulus since very early ages. E-modulus is a mechanical property depending on the advancement of the hydration reaction and the temperature stories during the curing, with the interesting characteristic of allowing non-destructive testing to be carried out. This paper presents an inter-laboratory and inter-technique comparative study of E-modulus evolution at several temperatures. Three laboratories were involved, contributing with specific testing techniques applied to a single mix of normal strength concrete: 1) BTJASPE (BéTon au Jeune Age, Suivi de la Prise et du module d'Elasticité), available at IFSTTAR in France; 2) EMM-ARM (Elasticity Modulus Measurement through Ambient Response Method) available at the University of Minho in Portugal; 3) TSTM (Temperature Stress Testing Machine), available at Université Libre de Bruxelles in Belgium.

    Authors: Molberg, Martin;

    Dielectric elastomers are highly promising as functional materials for the rapidly developing field of flexible actuator and generator technology. They offer a unique combination of low densities and large reversible deformations of up to more than 100% in area, and consequently have great potential for many new types of application. However, implementation has been impeded by the lack of specialized materials. The elastomers that have so far been investigated suffer from a number of disadvantages, including the need for very high activation voltages and limited service lifetimes. This thesis describes an investigation of the use of elastomeric composites as dielectric elastomers with the aim of optimizing and improving their performance in actuators. The influence of materials properties on actuation was first analyzed on the basis of a simple physical model and materials properties derived from standard test methods. The implications for the actuation performance of three conventional dielectric elastomers were then considered in detail. A preliminary conclusion was that the actuation performance could be improved if the permittivity of the elastomers were to be increased by modification with ceramic or conductive fillers. However, actuation performance was shown to depend not only on the permittivity, but also on the elastic modulus, the electrical breakdown strength, and strain hardening. Thus, although significant increases in permittivity were achieved by this approach, actuation performance was compromised by an increase in modulus in the case of the ceramic fillers, and a dramatic drop in electrical breakdown strength, in the case of the conducting fillers. A more promising approach was therefore suggested to be the use of an organic conducting filler encapsulated in an insulating matrix. It was demonstrated that it is indeed possible to increase the permittivity of a given elastomer while maintaining a high electrical breakdown strength. Different processing routes were investigated in order to control the dispersion of the filler and tailor performance. The optimum filler concentration, i.e. that providing the best compromise between permittivity and stiffness, was determined to be approximately 16 vol%, resulting in an improvement by a factor of 2 in actuation strain for a given applied voltage over that obtained with the unmodified matrix. Higher filler concentrations were also argued to have considerable potential for use in generators, given that the observed increased permittivity was also associated with high electrical breakdown strengths and increased strains at break. A threefold increase in converted energy per working cycle was predicted for a composite containing 25.5 vol% fillers based on a simplified model for a dielectric elastomer generator. Whilst these results are extremely encouraging, it is concluded that the composite approach has, in general, only limited potential as a means of obtaining further increases in actuation performance. The major difficulty remains that the use of a relatively rigid second phase to increase dielectric performance will inevitably also increase the elastic modulus beyond a certain filler concentration. As argued in the final part of the thesis, the way forward may therefore ultimately depend on the development of new types of synthetic elastomeric matrix materials that combine intrinsic improvements in electrical response with reduced moduli.

    We report on surface channeling experiments of singly charged ions on single crystal surfaces of Pt(1 1 0) and Pd(1 1 0). Using a time-of-flight system installed in forward direction we analyze the energy distribution of the scattered projectiles. By variation of the primary energy and the angle of incidence we investigate effects of the perpendicular energy on the channeling features. The perpendicular energy is defined as E-perpendicular to = E(0)sin(2)psi with psi the angle of incidence. In combination with precise azimuthal rotations of the crystal, we are sensitive to axial channeling and obtain information about the limits of axial surface channeling. From a comparison with detailed trajectory calculations we find that axial channeling effects are most pronounced for a perpendicular energy between 5 and 20 eV. As a result, we obtain an exemplary channeling map for the interaction of nitrogen ions with the (1 x 2) reconstructed Pt(1 1 0) surface identifying different channeling regimes.

    This report draws on the results of a self-assessment survey conducted on national adaptation policy processes in Europe. In May 2013, the survey was sent out by the European Environment Agency (EEA) to authorities in countries responsible for coordinating adaptation at national level (the EEA 32 member countries, and in Croatia in July 2013 as a new EU Member State and EEA member country). Some 30 EEA member countries provided their responses on a voluntary basis. Thanks to the high response rate and the wealth of information provided by these European countries, this report presents a unique collection of information and the largest and most comprehensive overview of national adaptation policy processes in Europe, to date.

    In this paper, the performances of two iron-based syngas-fueled chemical looping (SCL) systems for hydrogen (H2) and electricity production, with carbon dioxide (CO2) capture, using different reactor configurations were evaluated and compared. The first investigated system was based on a moving bed reactor configuration (SCL-MB) while the second used a fluidized bed reactor configuration (SCL-FB). Two modes of operation of the SCL systems were considered, namely, the H2 production mode, when H2 was the desired product from the system, and the combustion mode, when only electricity was produced. The SCL systems were modeled and simulated using Aspen Plus software. The results showed that the SCL system based on a moving bed reactor configuration is more efficient than the looping system with a fluidized bed reactor configuration. The H2 production efficiency of the SCL-MB system was 11 % points higher than that achieved in the SCL-FB system (55.1 % compared to 44.0 %). When configured to produce only electricity, the net electrical efficiency of the SCL-MB system was 1.4 % points higher than that of the SCL-FB system (39.9 % compared to 38.5 %). Further, the results showed that the two chemical looping systems could achieve >99 % carbon capture efficiency and emit ~2 kg CO2/MWh, which is significantly lower than the emission rate of conventional coal gasification-based plants for H2 and/or electricity generation with CO2 capture.

    Abstract In this article, we investigate the intergenerational transmission of sustainable consumption practices. Whereas previous studies have used self-reported attitudes and behaviour, this study uses data on actual energy consumption for space-heating and hot water combined with extensive panel data from Danish administrative registers. The paper shows significant intergenerational correlations between the energy consumption patterns of adults and their mothers, also when controlling for the energy consumption of the mother-in-law, where possible. Furthermore, it shows that the intergenerational correlation is slightly stronger for adults with lower income levels. These results suggest that energy consumption practices are shared and reproduced within the family. Following theories of practice, the intergenerational similarities in energy consumption practices refer to bodily learned practices that are indirectly transmitted and negotiated through family relations. In this way, these findings also contribute to a better understanding of how practical understanding regarding how to perform practices is transmitted within more ordinary aspects of consumption that play a less obvious role in distinction. To ensure more sustainable consumption practices in the future, this paper points to the importance of the role of family relations and the transmission of embodied practices.

    Nowadays, many construction companies use maturity-based approaches to support decisions that have strong impact on costs and sustainability of the construction process, such as: age of pre-stressing operations, decision of propping/formwork removal; instant of subjection to load, etc. Current approaches to quality control through maturity consist in evaluating the compressive strength evolution of the concrete mix at a reference curing temperature (usually 20°C), together with the determination of the apparent activation energy (Ea) of the mix. The value of Ea is usually obtained from one of these three sources: (i) reference recommendations based on the type of cement; (ii) calorimetric testing; (iii) testing of compressive strength evolution at several distinct temperatures. The only technique of determining Ea that really addresses a mechanical property is the latter one, demanding however the deployment of many specimens and tests. Furthermore, the destructive character of this technique limits the possibility of maintaining the same specimen for the entire Ea testing, thus increasing the variability/scattering of results. The present study intended to evaluate the possibility of assessing mechanical-based activation energy for concrete through continuous or quasicontinuous assessments of E-modulus since very early ages. E-modulus is a mechanical property depending on the advancement of the hydration reaction and the temperature stories during the curing, with the interesting characteristic of allowing non-destructive testing to be carried out. This paper presents an inter-laboratory and inter-technique comparative study of E-modulus evolution at several temperatures. Three laboratories were involved, contributing with specific testing techniques applied to a single mix of normal strength concrete: 1) BTJASPE (BéTon au Jeune Age, Suivi de la Prise et du module d'Elasticité), available at IFSTTAR in France; 2) EMM-ARM (Elasticity Modulus Measurement through Ambient Response Method) available at the University of Minho in Portugal; 3) TSTM (Temperature Stress Testing Machine), available at Université Libre de Bruxelles in Belgium.

    Authors: Molberg, Martin;

    Dielectric elastomers are highly promising as functional materials for the rapidly developing field of flexible actuator and generator technology. They offer a unique combination of low densities and large reversible deformations of up to more than 100% in area, and consequently have great potential for many new types of application. However, implementation has been impeded by the lack of specialized materials. The elastomers that have so far been investigated suffer from a number of disadvantages, including the need for very high activation voltages and limited service lifetimes. This thesis describes an investigation of the use of elastomeric composites as dielectric elastomers with the aim of optimizing and improving their performance in actuators. The influence of materials properties on actuation was first analyzed on the basis of a simple physical model and materials properties derived from standard test methods. The implications for the actuation performance of three conventional dielectric elastomers were then considered in detail. A preliminary conclusion was that the actuation performance could be improved if the permittivity of the elastomers were to be increased by modification with ceramic or conductive fillers. However, actuation performance was shown to depend not only on the permittivity, but also on the elastic modulus, the electrical breakdown strength, and strain hardening. Thus, although significant increases in permittivity were achieved by this approach, actuation performance was compromised by an increase in modulus in the case of the ceramic fillers, and a dramatic drop in electrical breakdown strength, in the case of the conducting fillers. A more promising approach was therefore suggested to be the use of an organic conducting filler encapsulated in an insulating matrix. It was demonstrated that it is indeed possible to increase the permittivity of a given elastomer while maintaining a high electrical breakdown strength. Different processing routes were investigated in order to control the dispersion of the filler and tailor performance. The optimum filler concentration, i.e. that providing the best compromise between permittivity and stiffness, was determined to be approximately 16 vol%, resulting in an improvement by a factor of 2 in actuation strain for a given applied voltage over that obtained with the unmodified matrix. Higher filler concentrations were also argued to have considerable potential for use in generators, given that the observed increased permittivity was also associated with high electrical breakdown strengths and increased strains at break. A threefold increase in converted energy per working cycle was predicted for a composite containing 25.5 vol% fillers based on a simplified model for a dielectric elastomer generator. Whilst these results are extremely encouraging, it is concluded that the composite approach has, in general, only limited potential as a means of obtaining further increases in actuation performance. The major difficulty remains that the use of a relatively rigid second phase to increase dielectric performance will inevitably also increase the elastic modulus beyond a certain filler concentration. As argued in the final part of the thesis, the way forward may therefore ultimately depend on the development of new types of synthetic elastomeric matrix materials that combine intrinsic improvements in electrical response with reduced moduli.

    We report on surface channeling experiments of singly charged ions on single crystal surfaces of Pt(1 1 0) and Pd(1 1 0). Using a time-of-flight system installed in forward direction we analyze the energy distribution of the scattered projectiles. By variation of the primary energy and the angle of incidence we investigate effects of the perpendicular energy on the channeling features. The perpendicular energy is defined as E-perpendicular to = E(0)sin(2)psi with psi the angle of incidence. In combination with precise azimuthal rotations of the crystal, we are sensitive to axial channeling and obtain information about the limits of axial surface channeling. From a comparison with detailed trajectory calculations we find that axial channeling effects are most pronounced for a perpendicular energy between 5 and 20 eV. As a result, we obtain an exemplary channeling map for the interaction of nitrogen ions with the (1 x 2) reconstructed Pt(1 1 0) surface identifying different channeling regimes.
