T1 - Agenda 2020 for a European Certification System for CBRNE Sensor Systems and Devices - the Concept for a Road Map T2 - 1st International symposium on development of CBRN defence capabilities N2 - Developments for technologies were initiated by the European Commission to improve future response capabilities and strategies to prevent terrorist attacks, to reduce the vulnerability to terrorism and to minimize the extent of damage from terrorist attacks. CBRN civil protection faces a growing significance in this concept and modern detectors and detection systems play the key role for a future reliable functioning that counters terrorism in Europe. The European Union is supporting the project CREATIF which is dedicated to provide a communication platform for technology users and decision makers, providers, and testers. First ideas were designed, strategies developed, preconditions and rules were named for a future internationally recognized certification system. A concept for a future European Certification System for CBRNE Sensor Systems and Devices and Processes has been developed, which is described in more detail.

T1 - Hierarchically porous and mechanically stable monoliths from ordered mesoporous silica and their water filtration potential JF - Nanoscale Advances N2 - Mechanically stable structures with interconnected hierarchical porosity combine the benefits of both small and large pores, such as high surface area, pore volume, and good mass transport capabilities. Hence, lightweight micro-/meso-/macroporous monoliths are prepared from ordered mesoporous silica COK-12 by means of spark plasma sintering (SPS, S-sintering) and compared to conventionally (C-) sintered monoliths. A multi-scale model is developed to fit the small angle X-ray scattering data and obtain information on the hexagonal lattice parameters, pore sizes from the macro to the micro range, as well as the dimensions of the silica population. For both sintering techniques, the overall mesoporosity, hexagonal pore ordering, and amorphous character are preserved. The monoliths' porosity (77–49%), mesopore size (6.2–5.2 nm), pore volume (0.50–0.22 g cm-3 ), and specific surface area (451–180 m2 g-1) decrease with increasing processing temperature and pressure. While the difference in porosity is enhanced, the structural parameters between the C-and S-sintered monoliths are largely converging at 900 C, except for the mesopore size and lattice parameter, whose dimensions are more extensively preserved in the S-sintered monoliths, however, coming along with larger deviations from the theoretical lattice. Their higher mechanical properties (biaxial strength up to 49 MPa, 724 MPa HV 9.807 N) at comparable porosities and ability to withstand ultrasonic treatment and dead-end filtration up to 7 bar allow S-sintered monoliths to reach a high permeance (2634 L m-2 h-1 bar-1), permeability (1.25 x 10^-14 m2), and ability to reduce the chemical oxygen demand by 90% during filtration of a surfactant-stabilized oil in water emulsion, while indicating reasonable resistance towards fouling.

T1 - High specific surface area ordered mesoporous silica COK-12 with tailored pore size JF - Microporous and Mesoporous Materials N2 - Ordered mesoporous silica materials such as COK-12, analogous to the well-known SBA-15, are characterized by high surface areas and unique features such as defined pore sizes in the meso-size range and high pore ordering. The aim of this work was to prove the washing step and choice of calcination and aging temperature during the COK-12 synthesis as effective tools in tailoring, markedly improving the specific surface area, pore size, and pore volume. By controlling the aging temperature, the pore size was linearly adjusted between 5.7 and 8.1 nm, while preserving the hexagonal ordering of the pores. The synthesized COK-12 powders possess pore volumes and specific surface areas up to 1.23 cm3 g−1 and 860m2 g−1, respectively, which is markedly higher than what has previously been reported about COK-12. The presented results and the environmentally friendly character of the synthesis will make COK-12 more interesting for future adaption to the industrial processes, for example in catalysis, adsorption, or drug delivery.
